Once Yu Ziyi passed through the book, he was taken away by the Demon Lord. He knew the ending of the story, so he tried his best to escape, but the direction of things still did not change. The truth about passing through the book gradually emerged, and he also understood that some things cannot be changed, but the ending developed in another direction because of his changes.
Concept: Fate is destined by God, but opportunities must be fought for by oneself, and results must be changed by oneself.
