One Punch System: Obtain the Emperor Engine at the Beginning

I was originally a kind of farmer, living an ordinary life of farming year after year, but my life was completely changed by a crystal. The leader of a sect? Sorry, I was dead with one punch. Everything in this world will be reduced to nothing the moment I swing out my fist. Are you faster than me? I, Flash Flash, am dissatisfied. Are you the best puppet master in the world? Sorry, I, Metal Knight, will be gone with a nuclear bomb. In short, I am just an ordinary little genius who can do everything. This novel and its characters are purely fictitious.
