Yu Wanchao travels through various worlds, correcting the changed novel world, eradicating those who try to change the world, not interfering too much, and ruling by inaction. The tide comes and goes without a trace, until it is accomplished and retired, it never stays in a certain world for long until a certain day. First of all, there is no cp, and secondly, there is no cp, thank you! Uh, no cp refers to the protagonist having no cp, just to add.
Purpose: Don't try to change the world unless you can endure the butterfly effect.
