My System Can Only Deliver Food

Wu Yanzu gained the ability to teleport, but the System was a real scoundrel: it restricted him to using this power for food deliveries and even imposed a time limit. Furious, Wu Yanzu tried to uninstall the System, only for it to start a countdown to his death. To stay alive, he was forced to become a delivery guy. A wish-fulfillment story with multiple heroines, guaranteed to be a great read.
