Naruto: Reborn as Neji Hyuga After Dying in One Piece - Chapter 2. The Cheat Code!

Crying blood and tears, she pledged a poisonous vow. The gods did not fail her. She was sent back to a decade ago. The legitimate daughter of Jiang family returned from hell.

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”.

The once-bustling and noisy streets were now filled with an eerie blanket of silence.

Hoarse and frenzied whispers lingered high above the heavens, and an indescribable ancient giant lurked in the shadows of the bottomless ocean.

A mysterious plague had outbroken, and natural disasters wrought the Earth. Global pandemic and catastrophes had the panicked masses seeking illusory shelters from the devastation, day and night.

A bloody shower poured over the land as the streaks of lightning tore across the sky, illuminating the ill-intentioned gathering of ravens above. Nevermore, nevermore, quoth the ravens.

“We can see that this malformed creature has twelve pairs of ribs like humans, but also has a “transverse bone” that humans do not possess…”

In the medical school, Gu Jun continued bringing down his scalpel, illustrating the abnormal thoracic structure of the malformed cadaver on the dissection table to the surrounding students.

Ominous and treacherous times had descended! Truth and logic had crumbled, order warped into a frenzy. Humanity can only forge ahead through the power of intelligence and wisdom.

A reader has been watching Hanyu for so many years and can’t help but revolt!

This is a Korean entertainment in my imagination, not a stallion, not a red palace. Korean entertainment that is as close to real life as possible
