Magical God in Tensura

An otaku boy after going to sleep the next day wakes up and realizes that he died and reincarnated in the verse of "tensei shitara slime datta ken" as the Magical God Othinus and all his powers as a magical god. After finding out where he was, he decided to embark on his adventure in the new world while getting stronger. (N\A: I hope you like this tension fanfi and I hope you forgive the mistakes you make. If the mistakes are very annoying, then comment and I will try to fix them. With all this said, I hope you enjoy my story).
