Is there really no superman or superpower in this world? Are the myths about gods, emperors of heaven, kings of hell, etc. That have been passed down from ancient times all fiction? Not really.
In this world, everyone can become a superman.
Maybe you fell down, or you were bitten by a spider, it may cause genetic mutation and awaken to become a superman. When you successfully awaken and become Superman, you will receive a notice, an admission notice from the Superman Academy...
PS: An admission notice from the Superman Academy completely changed his destiny, but after a big wedding, Pigfoot suddenly discovered that there was a larger and more mysterious world waiting for him... (I used my powers as a guide, but I am bound to reach the pinnacle of myth! Liu Jianyun's words.)
