Transmigrated Big Shot: The Villain Starts by Conquering the Elves!

[Refining and fusion + multiple heroines + villains + transmigration + having fun at others’ expense...] Protagonist: Meng Tian. My name is Meng Tian, and I have the ability to refine and fuse things. I transmigrate through one world after another, encountering Gu Cicadas, Hallucinogenic Slimes, the Starfury Realm, Human Emperor Banners... Elves, princesses, noblewomen, witches, beast-eared girls, princess consorts, school beauties, swordswomen, female sword immortals... Treasures, beauties, resources, and Systems: I’m taking them all for myself! “Don’t try to reason with me. You’ll be dead before you get the chance!” “In my eyes, there are only people who are useful to me and people who aren’t.” “Either die or become my slave. Pick one. You have ten breaths to decide.”
