One Piece - I Am A Different Luffy! - Chapter 456 - 454 - Wano 09.

Three Souls lay in one body,

One soul belonging to a man who had reached the peak, the strongest there ever was, the one who had the talent to do so. Yet he suffered because of his talent. His soul shone as bright as a galaxy once, but now is but a sun. His talents made him the envy of all.

And He lost it all.

The Second soul belonged to a man soon to be the richest in the world.

A man who had his face charred, a man who seemingly had every odd placed against him from the very beginning.

He went against the family that abused him and triumphed over them. Yet he was left broken inside, He craved a release, and the first soul brought him that release.

And he became a psychopath that scared the manifestation of evil itself.

And the Third?

The child born from their souls was anything but ordinary. Cursed with a fate no one wanted. Cursed with the fact that the Universe wanted him dead.

He was born from Chaos And Ice and a fraction of light, Yet manipulated Space.

His abilities were so powerful they were harmful to his body.

His talent is as infinite as the boundless cosmos.

His enemies were greater than one could count.

His luck is worse than shit.

And Yet, he continued to fight. Despite whatever was thrown at him, he would brute force through it or outsmart it, befitting the other two above.

He continued to fight, not believing in the bullshit that was destiny.

There is no rebirth through time, and there is no system of heaven to cut melons and vegetables;

There is no secret book under the cliff, and there is no great return pill from the dead;

There is no such thing as a full-fledged lust with a strange root and a sacred blood.

If it is said that Shi Jianren is an expert who has attained the Tao and joined the WTO,

Then Bai Haonan was a dazed fellow who smashed his head into blood.

The key is that he still feels that he is living a very happy life!

A story similar to the golden right foot,

A story about a dream,

It depends on what tinted glasses you are wearing.

In this world, orphans or just anyone without any hope for this world can apply to become a “walking target”. Their sole purpose is to be a practicing dummy for the students of the sect who train to become “Demon Hunters”. These students need “walking targets” to test their training on living, walking beings of flesh and blood.
In exchange, they will be provided with food & shelter.
Their existence value is lower than a slave, but if they manage to survive a few years they can receive a life long pension.

Xiao Han is such a “walking target”. One time he witnessed a powerful Demon Hunter disposing a demon. When the demon died, a fragment of the demon that managed to escape entered Xiao Han’s heart. No one saw that, and even Xiao Han himself only felt some discomfort for an instant.

But that thing in his heart soon gave Xiao Han visions, and the first one is of a cultivation method which allows Xiao Han to absorb damage to enhance his body. A perfect cultivation method for a “walking target”.
