How Do You Hold the Protagonist's Lap When He Is Born Hundreds of Years Later?

My name is Lin Bei, and I am wearing a book. Traveling into a doomsday novel, he became a passerby whose name never appeared. The only information I know is: more than three hundred years later, a savior named Jun Buyan will be born, and then the world will be destroyed. Yes, the savior was born, but the world was still destroyed. The original plot is so outrageous. In order to survive, I made a perfect plan: live to be more than three hundred years old, hug the lap of the savior, save the world, and then go home. The first step is to build a sect. Anyway, idle time is idle, why not save some wealth in advance for future bosses. But I never expected that my apprentice would gradually go astray in his painting style. The eldest disciple Chu Zheng, the last prince of the Great Chu Dynasty, the hegemonic body of the sky, whose mantra is "this is it". I took on such a disciple, and my main job every day was to argue with him. The second disciple, Liu Ruoyi, suffered from severe social anxiety. Her specialty was scolding me fifty times in front of my face, and then writing a short essay to keep on file after the scolding. Half of her sect diary is devoted to recording my various embarrassing moments. The third disciple, Huo Xiaoyu, is a naturally gifted lolita with strange powers. When she goes berserk, she can dismantle a mountain with her bare hands. When she is calm, she is afraid of crushing even a bowl. It took me two days to teach her one thing: you are not a monster, you are just strong. Later a few more came. The top assassin who is always sleeping, the profiteer who regards wealth as his life but always donates "slip-of-hand", the foodie who never has enough to eat, the narcissist who looks in the mirror anytime and anywhere... By the time I realized it, Lying Pingmen had become a "mental hospital" recognized by the world of cultivation, and I, the leader, was the director.
