Prophecy of the Old Gods

Zhang Zilu, who was frustrated in life, accidentally traveled to the world after the death of the old gods. This is a world of Taoism, devils, and superpowers. Some people say that our Taoist sect will resist the great catastrophe in the world; some people say that those who slay dragons will eventually become evil dragons. Zhang Zilu does not believe in evil. He wants to break the prophecy, enter Taoism, become an immortal, and kill gods.
