What is the red occurrence in the perfect world?

Source Shi Tian will have red hair in his later years and become a monster. It's not a monster, it's a corpse.

This kind of corpse is called a Promethean. Because of Shi Tian's blood, I am jealous, and I won't let them live long, but I can't kill them myself. Only turning them into Prometheans, Prometheans, is a kind of corpse change. That is to say, when the source Shi Tian stole the nature of heaven and earth, it was equivalent to selling his life again, but he could not die. Dusk is also the weakest time for Yuan Shi Tian, and it is also the time to change the body.
