The Bald Devil with a Contract, I Was Laughed at by the Whole Internet

[Contract One Punch Superman Hero + Pure Coolness + Decisive Killing + No Pressure] Global changes occur and monsters attack. Fortunately, humans can also contract heroes. If the contract is successful, they can obtain the hero's abilities. Lu Chenzhou, who traveled through time, discovered that all these heroes came from the One Punch Man anime. Everyone is pursuing A-level/S-level heroes. Only Lu Chenzhou knows that the C-level hero - the bald devil Saitama is the most invincible. On the day of the contract, Lu Chenzhou decisively contracted with the bald devil Saitama, and was ridiculed by the entire network. "I can't understand how to contract an S-class hero instead of an S-class hero." "Hahaha, there is really a fool who wants to contract a C-level hero. Is this person crazy?" "I guess he did it on purpose so that he could take advantage of the opportunity to become an Internet celebrity and then sell goods through live broadcast." Three years later. "Holy shit, why is the sky cracking? What happened." "Holy shit, a monster at the peak of dragon level was beaten into mud with one punch." "Holy crap, is this still a C-level hero?"
