Arifureta Shokugyou de Sekai Saikyou (WN) - Chapter 514

An accident gave Su Hao the ability to reincarnate infinitely.

But who can tell him why he can’t live past five years of age every time he is reincarnated?

The universe is dangerous and unfriendly to children.

Su Hao decided on his first small goal — to become an adult.

“How could I not even become an adult!”

…

Amidst Su Hao’s millions of reincarnations, one time after another. After obtaining enough knowledge, he discovered the way to become a god.

This is a mortal’s path to divinity. Maybe… you can too!

Chu Yang, the Ninth Master of the Nine Tribulations Sword, sacrificed almost everything he had for the sake of improving his martial arts, including the love of his life. After spending three years locating the fifth fragment of the Nine Tribulations Sword, he was ambushed by all sides at that very place. Mortally injured with no means of escape, Chu Yang executed a sacrificial technique by plunging the Nine Tribulations Sword into his very own heart. “With the blood of my heart, ten thousand tribulations will collapse!”

After witnessing the death of all his ambushers, Chu Yang’s vision began to darken. At a distance, moments before his death, he saw the mastermind who had plotted his downfall — Mo Tian Ji. With that, his eyes finally closed.

However, with a start, Chu Yang once again awoke to find that he had returned to when he was sixteen years of age! Furthermore, the Sword Spirit of the Nine Tribulations Sword now resided within his Dantian, the energy center of his body! From that very moment, Chu Yang would then begin to right all of his past regrets, and carve his very own legend by fulfilling his destiny as the final Master of the Nine Tribulations Sword, and defeating the Heavenly Devils beyond the realm of the Nine Heavens Continent.
