Arc 0 - Chapter 1: My Life

(Unknown)

Year 1: The Start

I was told that I was a bit different from the other children. For one, my first words weren't something like Father or Mother. Instead of just one word, I had nine words that appear in my mind out of nowhere one day.

A clear mind, and a silent and serene heart.

These nine words would always forever be with me throughout my life. I just never knew how much they affected me. But, no one knew about this. Not even my parents, as it took a few more weeks before I spoke out my 'first' word.

Year 2: The Strong Live, The Weak Die

Following up the next year; I realized another thing that I find myself curious about the surrounding around me. And something that's important for me to follow for the rest of my life.

Seeing my own Father kneel before a stranger, who I later learn was someone with a powerful background.

I learned that this world ruled by strength and the weak shall always have to lower themselves to the strong.

Year 3: Why Mother?

On the day I became three years old. My own Mother explained to me that she and I belong to an ancient family, but only us two are left while the rest is long dead. Killed by our family's enemies with no allies to help us. As our own allies betrayed us and join hands with the enemy side.

This is when my Mother hand me our family's [Forbidden Martial Arts: The Black Heaven & Earth Style] instead of the regular Martial Arts.

The reason why it's forbidden was that many users will fall into the side-effects of training this [Forbidden Marital Arts], where the users will be overwhelmed by extreme negative emotions and will kill everything around them.

As a child, I didn't even understand everything that my Mother said to me back then. All, I know is that I need to learn everything and practice the family's Martial Arts. And regain get our revenge on our family's killers.

Year 10: Please Get Better... Mother

It only took me 7 years to master the [Black Heaven & Earth Style].

However, my Mother wasn't in the right state of mind by then. I just wished I had spent more time with my Mother more than continue training the [Black Heaven & Earth Style].

As my Mother had become ill after Father left Mother and me behind for a rich lady, who took a liking to Father's look.

That is the first time I felt myself hating someone for the first time. Leading to the [Black Heaven & Earth Style]'s [Dark Intimidating Aura] to affect me at a young age.

However, thanks to my [Mantra: A clear mind, and a silent and serene heart]. I wasn't affected by the negative emotions from training the [Black Heaven & Earth Style]. But, that didn't stop the [Dark Intimidating Aura] from growing.

Now, my own Mother could barely do anything, causing me to learn how to take care of myself and my Mother. But, she continues to force me to work on my Martial Arts until no one could defeat me in battle.

Year 20: Family? My Mother Is My Only Family!

I learned many things while taking care of my Mother for over 10 years while keeping up my training as I promise my Mother to continue working on it. Which I continue up to now.

One: Never trust so easily. As I lost more money than I should thank, to the many people wanting to take advantage of me and my Mother, who could no longer get of bed at this point.

Two: Almost everyone would want something in return as an exchange for their help. Showing that no one in this world would do anything for free to a stranger, even to a close one. After all, the family on my Father side tried to offer a low price on the house my Mother and I own, as a way to help us by giving us the money to buy medicine for Mother to get better.

Sadly, the amount of money my so-called family. No. They no longer my family, but just strangers from my former Father's family. As the amount of money wasn't enough to even buy to help Mother.

Year 30: The Secret

It's a miracle my Mother lasted this long and enough to see me grow up.

At the age of 30; I buried my own Mother in the backyard of home by myself. No one came by to help. No one cared about the death of Mother. Not even my own Father. No, I shouldn't even call him Father at all. Like that man's family.

I found the diary of my Mother hidden underneath her bed, but it wasn't really a diary and more of a message to me. Like Mother knew I would find it the moment she died.

I learned that Mother never even married the man and got pregnant with me. It was out of the goodness of Mother's heart that allowed that man to stay with us for a while until he left for another woman after Mother allowed him to stay with us.

After what my Mother did for him, but he still abandoned us. That man will wish he has never abandoned Mother and me.

However, much to my horror, I found out that Mother wasn't ill at all. But, poisoned by the very same woman that man picked over Mother and me.

The only reason I'm still alive was that Mother uses a [Forbidden Technique] to give my body to be immune to all poison. At the cost of 80% of her lifespan.

Mother even gave up her Martial Arts by using another family's [Forbidden Technique] to transfer her Martial Arts into me, which allowed me to train the [Black Heaven & Earth Style] without any bad side-effects at the early age.

It's no wonder I managed to master the [Black Heaven & Earth Style] at the age of 10. And the reason why Mother continues to demand me to master all I could with the [Black Heaven & Earth Style]. As Mother went the same thing I did early on. And only useful up to the age of 12.

I would have gone and avenge Mother by killing the woman that poisoned my Mother. But, in the diary, mention that I need to go on a journal to find our family's main home. To gain the family's treasure, which is one of the many reasons why almost everyone desire to destroy my family.

Year 60: Immortal

It took me 30 years to find my family's main home, where it's at the peak of the tallest mountain, and one of the forbidden land, where dangerous beasts rest. And the only reason my family didn't come here to stay safe was due to the family's rules of only those that masted the [Black Heaven & Earth Style] may come here.

Upon arriving, I found out that it's in ruin and look like a battle has taken place. So, it looks like I won't be able to find any member of my family. And even this place wasn't a safe haven either.

Looking around the place; I found almost everything is destroyed. But, thankfully, I carried around my Mother's diary, even if it isn't really a diary in the first place. Near the end of the book; there are many draws of maps. Showing that Mother knew that the main home of our family would be ruined.

And I was smart enough to connect the dots, to know that my Mother was here before.

It took some time, but I follow the direction on the diary Mother wrote down, where she wanted me to go. Upon finding a hidden entrance, that leads to an underground room, where I found only a small room, that only has a table in the middle.

On the table; there are a few things. One of them is a note, that's covered in dust and a small red box that barely takes any space on the table.

Carefully take the note first, afraid that I may damage what may be a warning of some sort. However, it wasn't a warning, but a note from my dead Mother. Who really did come here before I was born.

As I read the note, I found out that this is a note to me and explained to me what's inside the red box, where I discovered that inside the red box was a pill of immortality and a pill to regain back one prime age.

The first pill will make anyone that eat this to become an ageless immortal. One of the many rare treasures of the world. Not the best immortal treasure, but still rare that would drive many Clans into madness to get their hands on this. Even if this one of the lowest-ranked immortal pill. Only making one ageless, that's it.

The second pill will make an old person regain back their youth, the prime of their life without any side-effect, other than they won't regain back those years from time itself. Only the appearance and the body of youth is regained back, while the lifespan of that person will remain the same. Very valuable towards people that desire to have a younger appearance than being so old looking.

Of course, even if these two are rare treasures, doesn't mean others haven't managed to get one themselves. In fact, Mother explained on the note, that the immortal pill was created by her own Father, while the youth pill was created by her Mother.

Both were meant for herself, but Mother didn't have the will to continue on in this endless torture called life. The only reason she continues on was to give birth to someone that can. Me.

I notice how Mother didn't write down my first name and just left the family's name instead, but I know this was for either me or someone that she gave birth to before me.

Either way, Mother experiences many things that would have made her kill herself right away. But, those things she will never tell me and take them to her grave.

Nonetheless, I know that Mother only continues to live as she could be to help raise me to become who I am.

Opening the red box, where I found two pills, one is white, while the other one being blue. The white one is the immortal pill and the blue being the youth pill.

I found another note, that has a few words, where I could stop now and just live my life how I wanted. If not, I must avenge the family upon eating these two pills as payment to eating them.

I've already promised myself to avenge Mother. So, I took both pills. Giving me back my youth, turning me back to my body back to my early 20s.

Even after 30 years of travels to come here, where I have taken many lives and escaped to keep my life, even if it means exchanging for someone else lives for mine.

For now, I'll start training again until I deem myself ready to take on my family's killers.

Year 100: Blessing Or A Curse?

40 long years. That's how it took me to completely master the [Black Heaven & Earth Style] and create other [Techniques] to go with it. Where I have created the [Heaven Destruction's Techniques]. A set of [Techniques] that could destroy the land itself by using [Ki] itself.

And the [Earth Rebellion's Techniques], another set of [Techniques] that mostly used in a defensive approach, but could still be used for an offensive. However, it lacks the destruction power in a wide range unlike the [Heaven Destruction's Techniques].

However, this wasn't enough as I found out that the woman and that man somehow gained a pseudo-immortal pill, where the consumers will require to consume the same pseudo-immortal pill every month to continue living.

A bit uncommon, but easier to obtain than the ageless immortal pill I have taken.

Honestly, this was a good thing for me. Because I lost track of time and was afraid I lost my chance of avenging Mother.

Knowing this, I didn't dare rush like I was about to. And throw myself back into training, to master those [Heaven Destruction's Techniques] and [Earth Rebellion's Techniques] I have created.

Year 200: Joining The Ranks

In the hundred years of training. I have made a name for myself in the world of Murim. People have started calling me one of the old monsters, where I have obtained the same rank as the other immortal beings.

Year 500: Lifeless

I've killed all those that killed my family. And even avenged my Mother's death by killing the same woman that poison her, along with the man that left Mother and me. Even after he begged for mercy. Sadly, I was out of mercy.

It took me hundreds of years to accomplish my goals. But, in the end, I was left with nothing. All I had was my Martial Arts and experience in countless battles.

I had no goal, making the world seem lifeless to me. But, the promise I kept with Mother, to continue to train the [Black Heaven & Earth Style]. So, I continue to fight and fight, until it becomes the number 1 Martial Arts in Murim in the process.

Year 1,000: Now, Immortals Are Involved

It took 500 years to make the [Black Heaven & Earth Style] the number one Martial Art in the mortal ranks. Now, all those that haven't reached the peak of their Martial Arts or immortal beings, will die before my fists.

But, I know this wasn't enough as countless of other Martial Artists have done the same as me. Now, I start the next level of battles. The battles of the immortals.

Of course, I made more enemies than allies. In fact, thanks to how I grow up in the environment of only just Mother and me. I have developed a trust issue, where my trust is almost impossible to be obtained.

Which is why many immortals have continued to hunt me down for killing their family members, I have killed for a simple reason to something complex.

Nonetheless, I have gained the title of Immortal Killer, for killing many immortal beings that are above my own ageless immortality, where they can revive themselves with just a drop of their own blood.

Well, I just had to use enough [Ki] to the point that even not a single drop of blood would remain, killing that immortal in the process. Which wasn't unheard of, but very rare to happen.

Now, more immortals started hunting me down to gain access to the [Black Heaven & Earth Style] upon learning that it has the power to kill immortal beings, even those that gained the top-ranked immortality.

Nonetheless, this didn't stop me from continuing to develop my Martial Arts. As I know there are other Martial Arts stronger than mine. So, I need to continue until I reach the peak.

Year 7,000: I'm Not There Yet

6000 years. That's how long it took me to kill 50% of the immortals in Murim. Now, the remaining 25% went into hiding, hoping that someone among them could kill me before revealing themselves back in Murim. While the other 25% continue to chase after me, where the 25% didn't have anything stopping them from entering a life and death fights.

I became one of the most wanted criminals in the Murim.

No longer able to enter any nearby cities without leading to an army trying to stall me long enough for the other immortals to come after me.

I wasn't at the point, where I can take a squadron of powerful immortal Martial Artists yet. So, I would always escape right away, not that these mortals could stop me.

Also, during these years I have to relearn how to cook my own meal by hunting down wild animals around me or just rob others for their supply of food.

Year 50,000: Battle Manic

New immortals have started rising as someone discovered the long forgotten methods to create the immortal pills. But, require very rare materials to do so. Turning this into the era of immortals.

Therefore, those immortals that I sent into hiding. Have started revealing themselves, and teamed up with the remaining leftover immortals that continue to chase after up to now.

Of course, this excited me, not scare me. Seeing how new Martial Artists will rise and will give me the challenge I needed, to continue improving my Martial Arts.

Even if I had developed to the point of taking on a team of 8 powerful immortals by myself. That doesn't mean I have reached the point of facing an army of powerful immortals.

Year 100,000: Era of Hatred

Nowadays; it wouldn't be shocking to see the immortals walking among mortals. However, thanks to the immortal pills created over the time. A new barrier has created between everyone, where in the past, all non-Martial Artists are weakling.

Now, it has become to the point of almost all immortal looking down on non-immortal beings, causing the mortals to hate the immortals. Making some of the new immortals to create a faction, to hunt down the previous generation of immortals.

Leading this to the end of the era of immortal, and entering the era of hatred. Where everyone will fight each other to the bitter end.

This shocked me for a short while until I continue what I did. Fight. Fight until no one can defeat me.

Year 1,000,000: Come, Come, And Fight Me!

At this point, I can't even remember my own Mother's face. Even her name is long forgotten. Even her diary has long been turned into dust through time. The only things I can remember my Mother by is the name she has given to me, my first name and allowing me to know my family's name: Tendou. Along with the [Black Heaven & Earth Style].

By now, I have gained the title: The Ancient One. As the new generation of immortals has killed the leftover immortals of the previous generation. Leaving me to the only one left.

Of course, there were a few powerful ones that could easily take care of the new generation of immortals.

However, it was thanks to me, that I have hunted them down to continue developing my Martial Arts.

So, I'm all that's left of the older generation of immortals and the one that faces the entire Murim by myself. Not like I haven't been by myself this entire time.

I continue to fight, and fight, and fight, until I'm the only one left on this mountain of corpses.

Year 300,000,000: Any Challenge At All?

I've already realized at some point, that the resources that the world provide to us will soon be at the point, those common herbs back in my time as a mortal Martial Artist will be a treasure at this time period.

The era of hatred had ended when I have reached the point of taking on an army of immortal Martial Artists on my own, without resting for years.

Now, it becomes the era of mortal once more. As there are no longer new immortal every single year like last time. Seeing how many people have long overused the resource this world has to offer us.

So for the time being, there will be only rare cases of new immortal, but by then, they are likely to be killed by those remaining immortals that rule of a territory and will kill those that have even the potential of overthrowing them.

Or I would end up hunting them down to see if they are any challenge at all. Of course, I could have left them alive to wait for them to get stronger, but I didn't. Seeing how I tried that many times already and I still end up killing them.

Therefore, I would wait in a hundred years or so, to see if they even have the potential to fight later on after they grow up to the point of giving me a challenge. If not, I would just kill them and toss it up on them being lucky to get their hands on some methods to become immortal.

Year 1,000,000,000: Not All Memories Survives

I have seen kingdoms rise and fall, even some of the immortals that have a worldly desire, like ruling over others are killed off at some point, either by a fellow immortal or by some methods that could kill immortals.

The world of Murim continues on; Martial Artists over the entire world continue to develop their Martial Arts, and prove themselves they are the top of everyone. A never ending of repeats.

Among the immortals, there are very few compared to the time when I was still mortal.

I tried to return back to my birthplace. Sadly, the place I used to grow up is long gone. I can't even find it anywhere now. Even the Tendou's main home has ceased to exist as well.

I continue on fighting, and fighting, as that's all I know at this point. The only thing I can remember is to make the [Black Heaven & Earth Style] the strongest Martial Arts there is. That no other Martial Arts could face it. And my own name.

I can no longer remember why I must continue on this endless path of mine. All I know is that I must continue moving forward.

I had no desire of teaching my family's [Forbidden Martial Arts] to strangers. Even if they offer the most valuable treasures for just learning the basics.

I just send them off, rejecting them all. Some even tried to threaten me when they thought I was some ordinary Martial Artist. Well, they end up being killed by just a blast of my [Ki].

Then those people's families came for revenge, but like those before them. They also lost their lives to me.

Then the next, and the next, until friends and allies involved themselves into this as well. By then, no one remains, and causing some immortals to look for me, but upon finding out who I was. They ran off with their tail between their legs.

I no longer had any desire to chase after them. As it's very rare to find any challenge. If there was any, then it would the new opponent will only last for a few seconds at best before dying by my hands.

Year Unknown: I Lost Track of Time

A clear mind, and a silent and serene heart.

This mantra continues to stay with me along with the other things I did my best to remember forever.

A clear mind, and a silent and serene heart.

I continue using this mantra to stop myself from being affected by the negative emotions or any emotions at all.

I have reached my goal and made my Martial Arts the best under Heaven itself.

Then, I had this one small idea that crazy enough to be my new goal.

Seeing how the [Black Heaven & Earth Style] became the number 1 under the Heaven. Why not go against the Heaven itself as well, and make it the strongest Martial Arts that surpass anything that the Heaven could come up with?

Making the [Black Heaven & Earth Style] a Heaven-defying level Martial Arts.

I knew this was a foolish goal, but I needed something to help me continue to moving forward and develop my Martial Arts.

I started exploring the world, to see if there any methods to enter the Heaven Realm.

I lost track of time. But, I heard someone accidentally found a pathway to an unknown realm.

I have no idea if this was the entrance to the Heaven Realm, but I took my chance. After all, my body has long developed to the point, where it's the toughest thing in this world. Even lava can't melt my skin, but I didn't test my luck in drinking the lava.

It took some time, but I have found it after having to go through many things to get me here. Well, it may be a lot to others, but for me, it may as well be just a simple walk.

Then again, the concept of time is kind of bad somewhat, with how I lost track of how old I am.

Anyway, while on this travel to the passage to the Heaven Realm. I started working on my Martial Arts in a different approach. Where instead of aiming to kill everything in my path.

I wanted to see if I could make it possible to use it to protect others as a way to see if I could develop my Martial Arts even further while restricted by having to protect someone or something from being attacked by others.

So, I delay my travel to the passage for a bit; well, to me a bit is just a bit, but for a mortal. It would be decades or even longer. Which I may have lost track of time while developing my Martial Arts to be able to face multiple enemies while protecting.

Took some time, for me, but I managed to get it the level I deem enough for me to resume my travel to the hidden passage to the Heaven Realm.

And I never knew it protecting is a lot harder than killing. Who knew? Well, even at my old age. You'll learn something new once in a while.

Now, that's out of the way. I've already arrived at the location where I heard the rumor about the passage to the Heaven Realm. No clue if it's true or not, but I'm taking my chances with it.

However, I took my chance just to see if it's truth or not. And boy did it take some time for me to get to the location, which happens to be inside a forest of all things.

Then again, the forest I'm entering is among the most dangerous in Murim, with this forest being called the Entrance to the Underworld from what the nearby folks told me when I asked for the directions.

At this point, I didn't care if this passage leads me to the Heaven Realm or the Hell Realm. As long I get a challenge to continue to improve my Martial Arts and make it the strongest there is. I'm fine either way. I just have to find another way to enter the other realm.

Of course, there was someone tagging along with me after a few decades ago. And it just happens to be one of the people I protected while I was using a different training method by defending at all time instead of going in the offensive.

Mikumo Kushinada is a curvaceous and very well-endowed woman who appears to be in her mid 20's. She has long waist length black hair, wears an open kimono to show off her bosom, and usually wears a wooded bead necklace around her neck.

Also, she is a fellow ageless immortal, and a genius in Martial Arts and that's saying something when it comes to me.

She literally managed to learn to recreate a few of my [Black Heaven & Earth's Techniques]. Mostly with the [Earth Rebellion's Techniques] than the other ones.

Of course, I didn't stop her from trying to recreate my own [Techniques]. As others did the same in the past, but almost all of them died from doing something stupid. Like trying to use one of the dangerous [Techniques] I created for the [Black Heaven & Earth Style].

By almost, I mean that Mikumo is the only one that managed to survive and learn a few of my [Techniques]. Also, she came up a method to prevent her from aging.

Did I mention that Mikumo is a genius in Martial Arts? Well, that and she a genius in medicines related subjects as well. So, yeah, Mikumo became an ageless immortal through her own effort instead of taking an immortal pill like I did in the past.

Now, you are thinking, why didn't I fight her if she such a genius to manage to recreate a few of my [Techniques] and figure out her own method to become the same type of immortality as me?

I do, in fact, fight her daily, and she improving at a rate that makes other immortal beings jealous of her talent.

Also, let just say, Mikumo helped me in more than one way that I could have known, even with the experience I have gained as an immortal.

Furthermore, the fact that she among the very few that survive on using my [Techniques] and last against me for an entire minute after learning [Techniques] she wanted from me and face me while using them afterward, to test her version against mine.

End result: she only lasted for a minute. Way better than the other immortals, that has more experience than her, but unlike them, she lasted an entire minute while they only lasted for a few seconds or less, and with me going easy on them. Same with Mikumo, but still managed to last longer than others.

No way was I'm going to kill her off, because she is the first one to do what many can't in this present era.

One: She did something that's impossible for others and successfully did.

Two: She can last against me an entire minute in a fight, even if it's just me using a few basic moves while limiting myself from not using any [Ki].

Three: She tricked me into making her, my wife. Shamefully enough, that I married someone that was a mortal before she became an immortal herself. But, I have some bit of honor in me to keep this vow. As long she don't betray me, then it's fine.

Not to mention how excited I am when the time comes where Mikumo arrives at my level. No matter how long I have to wait. After all, both of us got all the time in the world.

What? I should kill Mikumo for tricking me into marriage? Yeah, I honestly don't care if I get tricked or not. I have met many people, male or female, all the same to me. Hell, there were a few females, mortal or immortal, that tried the same thing like Mikumo. But, all of them failed and didn't have the same qualifications as Mikumo.

Yeah, being a bit biased, but who cares? I got a wife that has the same potential as I am.

Arrogance? Get to my level and defeat me! I'll accept it with a smile on my face as you kill me! Prove to me that you're nothing like me! Prove to me, you've surpassed me, then I'll find my own way to come back to life and find you, so we shall fight again!

This is what I continue to say to many decreased enemies whenever they ask the same questions to me about how Mikumo stayed with me and was taught by me. Again, I didn't teach anything, she recreated it on her own effort. I didn't do anything. Not even giving out pieces of advice on how to use those [Techniques].

So, I may have got a bit annoyed by the same questions being asked, to the point, I could recite the answers in order, word by word, by now.

Even Mikumo found this amusing, which is something rare as Mikumo is mostly emotionless. Which she believes keeping emotions in control is important for battle and that losing one's temper will dull one's skills.

Very true in some way, in fact, I even follow this as well by using my mantra. Who knew this was one of the main reasons why she tricked me into marrying her. Oh, sure, there love involved, after I relearned the whole concept of love again, from Mikumo of all people before she became emotionless after learning my mantra.

Also, learning to trust Mikumo after the multiple times she saved my life when I didn't know it at the time, but was mainly a useless effort on Mikumo's end. As I built up a resistance enough to counter all the things that can kill me over the years of my immortal life.

So, I guess it's kind of my fault for making Mikumo into an emotionless person, temporarily that is. At some time, there are rare moments Mikumo will show emotions, and it would be mostly related to me.

Now, instead of a single person heading into a new realm by themselves. I got a wife, still a bit of shocked that I got married and it took who knows how long before it took Mikumo, to force herself onto me after finding out I have close to no experience in love.

In a way to thank me for protecting her and giving her the chance to learn Martial Arts, even if it just a few basics needs to know, like how to use [Ki]. And it only took a few years to realize that those so-called basics need to know were something only my era knew, while the ones in this present era require external methods to be able to control their own [Ki] and manipulate them.

Now, it's just Mikumo and me, heading to the Heaven Realm or Hell Realm, either way, both of us are heading to the point of no return.

Mikumo is willing to follow me to the deepest of hell itself after what we have been through together. I can't say the same, but I'm getting there.

Therefore, Heaven or Hell, Meng Tendou and Mikumo Kushinada are coming your way! Prepare for the fight of your life!
