All realms have enabled me to achieve the Great Dao.

A laborer suddenly gains a cheat ability: he can travel to the 1970s and 80s, to a world he knows from movies and TV shows. He becomes a black marketeer. Later, he discovers that his cheat ability allows him to travel not only to the 70s and 80s but also to other worlds. He then freely roams the myriad realms, doing whatever he loves.
