Sorry, I'm Allergic to Superpowers!

A genetic war tore open Truman's world, bringing the mutants hidden behind it into the light... As it turned out, there was no such thing as peaceful years. It was simply that someone was shouldering the burden for us behind the scenes... The two great divine nations of ice and fire descended. Humans mutated, gained supernatural powers, and became slaves to the gods... Unwilling to let its citizens be enslaved, Huaxia established an undercover unit to keep all mutants outside its borders. The protagonist, Zhang Wei, is allergic to supernatural powers. By chance, he made a contract with a devil, got caught up in the scheme, and gained powers of his own. Seeing how ordinary people were being enslaved, Zhang Wei understood: the abnormal... must be purged! The world has no need for supernatural powers!
