Please Destroy the Main Timeline

Due to an accident, Mo Yu shuttles to a post-apocalyptic world, becoming the last Human on a Space Station. Just as he expects a 'Space Debris' bad ending, he discovers he can use a Shuttle to travel back to past timelines. He shuttles through the history of humanity's extinction, witnesses the changing of eras, fights against various Monsters and alien races, achieves the good ending for every timeline, and saves all of humanity. Bloodline Emperor? Spider Mother? Beast Lord? Corpse Emperor? Eight Sages? Dragon Venerable?... Facing the legendary Monsters that stirred up the world in historical records, Mo Yu says: "As long as I catch them when they are young and start a cultivation plan, I can get a Legendary Grade Pal, and then have them fight themselves. What? Can't beat them? Then I'll just go catch some legendary Human heroes. With an all-legendary lineup, how could I possibly lose?" — Description from novelcodex.orgFull novel: Please Destroy the Main Timeline — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
