500 years ago, Chen Xi was devoured by a crack in the void and was transported into a cultivation world.

“Zhong Nuannuan, your charges have been withdrawn. The courts have declared you innocent and pronounced you not guilty for murder. You can leave prison now. Your family is waiting for you in the waiting room outside.” Zhong Nuannuan was startled. She pushed the female prison guard to the side and ran toward the waiting room. She did not even bother to put on her shoes. If not for the icy feeling she felt at every step of the way reminding her that this was not a dream, Zhong Nuannuan would not have believed that she had resurrected.
As she burst through the doors and saw him again, she knew in her heart, that this time she would get it right. This time she would cherish him properly and hopefully, just hopefully, turn her own fate around.

The next time he opened his eyes, the boy had become an “Undead” of the lowest rank through the power of an evil Necromancer.

The boy rejoices at having his earnest desire fulfilled, which is a body that will never feel pain. However, he realizes that he is still under someone’s control and how it was no different from when he was cooped up in the hospital ward.

But the world would not leave alone the boy who only wished for peace.

The Necromancer who revives the boy from the dead, names him “End” and attempts to gain control over him.
