Cursed Fantasy World

Ronkai is a brilliant inventor who was on the verge of creating the most powerful invention of all time, a cure for cancer and all diseases. However, it backfired when he injected the serum on himself and led him to his death. Through this unfortunate fate, he meets a Japanese god who is not fond of Ronkai being American. He was sent to the wrong afterlife and reincarnated into a fantasy world that feels like a curse. The racist god gave him no abilities, no weapons, or anything to help. Now he must wander around, surviving in this world, building what he can, and trying to live a somewhat decent life.
