After Death, I Became the System

When the blood butterfly, which symbolizes death, flaps its wings, people with evil hearts become bloodthirsty demons, but the birth of a demon requires a sacrifice, and this sacrifice is life. Li Yanxi, who was innocently sacrificed, became the Purification System of All Realms after his death. Since then, it has traveled through the heavens, entrusting different hosts to purify all realms. Let the young man whose emotions and passion have been taken away by the gods become a god-killer. Let the good-for-nothing who refuses to be mediocre walk on the path of immortality, rise to the top, and become invincible in the world. Enlighten the people's wisdom and spread magical powers, so that the human race, which has become the food of all races, can once again become the masters of this ancient world.
