Infinite Realms: Starting Out as a Fatui Lab Rat

Wang Lei, an ordinary wage earner, had an up-close encounter with an airplane on an elevated highway. Then he was struck by this new century's transmigration starter and transmigrated to another world. Unfortunately, Wang Lei soon discovered that in this new world, he was a Reincarnator in the Transcendent Paradise. And the fate awaiting him was to become a guinea pig in the Fatui's laboratory. Fortunately, Wang Lei endured the experiments and acquired the bloodline of a dragon. In the Fairy Tail world: Wow, this Take Over Magic sure is useful. In the Akame ga Kill! world: That Imperial Arms of yours looks nice. Mind if I have it? In the Holy Grail War: How do I deal with being born with a debuff? Feige, I was wrong! The Paradise's overseers watched on: ...How did this weirdo end up in our plan? The overseer named Nothingness: I don't know. I'm just a slacker. He's not my messenger, so don't ask me. The overseer named Aha: Haha, what a riot.
