Dragon Clan: I Have the Law of Cause and Effect.

Ling Heng travels through the Book Dragon Clan but ends up reaching the finale. The awakening of the Word Spirit causes first and then the cause, but what he has to face is Nidhogg who has fully awakened. "I definitely can't beat this. What if I go back to thirteen years ago for some reason?" Nidhogg:? Why did people disappear? "What if after the death of the King of Bronze and Fire, his body split into an old Tang who knew nothing?" Old Tang: Lu Mingfei, I'm going to torture you tonight on StarCraft! "If the King of Earth and Mountain chooses to hand over power to Ling Heng in the end, he will be with Chu Zihang as a hybrid." Xia Mi: Chu Zihang, you promised to get married, and you are not allowed to go back on it. "Suppose the king's clapper breaks at a critical moment" Eri: Sakura, let's go to China together, okay? Ling Heng: What does it mean that if I kill Nidhogg, I will become the new king of the world? [Single heroine][Female protagonist Su Enxi]
