Description

Killed by a goddess and reincarnated into another world, a genius scientist awakens in a realm ruled by magic. But instead of spreading modern Earth technology as expected, he follows his boundless curiosity—doing whatever he pleases. No cheats, no overpowered magic. Just pure intelligence and psychological warfare. Thus begins a reincarnation fantasy unlike any other, where science clashes with sorcery!
