The Useless-Father System Takes Me to the Top

System: Hey, kid, want to get stronger? We've got everything here: spirit weapons, magical treasures, immortal artifacts, divine weapons, beauties, and goddesses. Sign this contract and they're all yours~ Ye Chen, who had transmigrated here, heard the System's voice and his eyes lit up. Without a second thought, he nodded. “I'll sign!” When the System started issuing one inhuman task after another, with pitifully small rewards, just like that certain shopping app, Ye Chen finally realized he'd been scammed... Ye Chen: “You damn System, I'm breaking this contract!” System: “Heh. Break the contract and I'll erase you on the spot! Get to work for me, kid.” This ridiculous System cracks jokes while I, Ye Chen, take a drag on my cigarette. The synopsis won't do this story justice, so please head straight to the main text.
