After delivering his last takeout order, Feng Yu was driven to a dead end by malicious negative reviews. The company wanted to fire him, and the landlord wanted to evict him - a complete social death. In a desperate situation, a sentence suddenly popped up in his mind: "Ding! The sign-in system of the world has been activated. The first sign in the novice village will be rewarded with the full level of "Nine Yang Magic"!" From then on, he traveled through the world on an e-donkey: signing a strange fire to light the kitchen in the Battle of the Sky, and signing an infinite gem as a keychain in the Marvel world. The female white-collar worker who knelt down and licked him yesterday was crying and begging him to give him a piece of abalone; the security captain who called him a dog yesterday kowtows to recognize his elder brother. Don't ask why the delivery guy is so crazy - just ask him to sign into all realms, and the heavens are moving sideways!
