Li Lei, who died from nuclear radiation, traveled to Demon Slayer: Kimetsu no Yaiba and became the Lower Moon 5 Lei, where he met Muzan Kibutsuji.

Facing the Ghost King who can read minds, he survived because of his special physique?

He also gained the favor of the Demon King Muzan. After that, he lived in Demon Slayer. During his time in Demon Slayer, Li Lei discovered the evil of people and the helplessness of becoming a demon.

If it is instinctive for ghosts to eat humans, then it is pure evil for humans to eat humans.

Soon Li Lei discovered that he had great power and could kill those who disliked him at will and save those who had a tragic fate.

From then on, Li Lei liked to become stronger. For this reason, Li Lei would try every possible means to become stronger, so strong that no one could hurt him, so strong that the world would revolve around him.

Whether it's the breathing techniques of the Demon Slayer Corps or the blood demon arts of the demons, they will all be nutrients for one to become stronger.

"A wild girl from the streets suddenly becomes a living Yama? Su Qi merely saved a child rolling his eyes in a dilapidated temple, yet she uncovered a series of bloody cases—black blood seeped from the coffin of an old woman at the village entrance, sharp teeth grew on the clay statues in the local temple, and most horrifyingly, the blue spots on the child's neck were exactly the same as the wounds her wet nurse suffered before her death. Until half a page of the Qingnang Notes popped up in the system space: 'The day the Heart-Eating Gu revives will be the beginning of the end for medical cults.' When she used the spiritual energy of the medicinal veins to activate the thousand-year-old ginseng and used needles to nail the vengeful ghosts attached to the woman in labor into a sieve, the truth hidden beneath the tide of cults finally surfaced—those who besieged the Qingnang Sect a hundred years ago were not the Alliance of Cults, but traitors of the medical path controlled by the Heart-Eating Gu! Watch as the little female doctor, stepping over the corpses of cults, rises from a poor girl gathering herbs to become the healer of the world's medical alliance!"

In his new life, he chose to hunt for destiny, keep the supreme inheritance for himself, and live only to pursue immortality.
