Monitor: Become a Legend from Scratch

Kill kill kill, don't create an absolutely perfect peace line + have a female protagonist + private setting + some weird things (referring to allies and enemies in the multiverse) [General introduction] This is a blue star, but it's not that blue star. Toilet Man, a guy with a human head but a toilet body. No one knows where they come from since the war broke out. In order to fight against this kind of alien, humans began to develop half-robots called monitors to fight against them. And "I"? "I" is Jiang Yun, a person who has traveled through this strange world... The difference from them is that I know the possible plot of the world developing backwards, but as the world view is established, the story gradually begins to advance in another direction. A few years later, when a mechanical life form named Lan stood on the moon and looked at the darkness in the distance and the real enemy from the darkness, he realized that he had become a true legend.
