I Rescued a Real Ancestor from a Fake Book

Jin Yaoning was an utterly ordinary college student majoring in esports. He’d transmigrated into a book before, so what? He had plenty of experience and could handle all sorts of scenarios with ease and care. Plus, he came with a book-transmigration System and spoilers. What could he possibly not know? He was the golden finger incarnate! But once he transmigrated, he realized the character and plot didn’t quite match up. So be it, he told himself to stay calm. He and the System had a clear goal: even in a heavily rewritten fanfic, he only had to find the one true male lead in this world, then use his broad-as-the-sea heart, love, and selflessness to move him, help him, and take him around in search of opportunities so he could quickly become the protagonist. Then, once the male lead had mastered his cultivation, he would split open the Heavenly Gate with a single sword strike and send Jin Yaoning back to his original world. That would complete his and the System’s mission. Everyone would be happy. He just hadn’t expected that after mastering his cultivation, the male lead would rather abandon this world brimming with spiritual energy and return with him to a world without cultivation. Jin Yaoning: O.o Was I a little too caring?
