Bookmarks of All Realms

I have a bookmark and I will travel all over the world. Smiling proudly in the rivers and lakes, on the top of Huashan Mountain, fighting with swords against the heroes; under one man, fighting Zhuge Qing at night on Longhu Mountain; among the eight deities and dragons, leading the crowd to fight for immortality, I am the Supreme Being; in the zombie world, ghosts and corpses surround Yizhuang, but I am invincible... In each world, I try to turn the tide again and again. This is a story about an outsider who is treated as a protagonist, gets opportunities in various worlds, and fights against demons.
