Chen Xu, a garbageman at the bottom of the giant city, digs out leftovers from the radioactive waste every day. Today, he pulled out a rusty metal piece from a pile of discarded prosthetics, with the inscription on it: "The thirty-seventh time traveling, for me at the age of twenty-seven - don't use that card." The next second, a mechanical sound rang in his mind: [The contract system was successfully bound, and the reward was a supply box from the "Future Chen Ruins"]. Opening the box, there was half a bottle of purified water, a pack of antibiotics, and a note: "Don't save me, she will die." When the search team from the upper-level Spiritual Weapon Sect rushed into the Rust Sea area and captured the child who was hiding the prosthetic limb, Chen Xu crushed the note. He activated the summons for the first time - his future self walked out of the light door, half of his body had become mechanical, and asked him with empty eyes: "Have you thought clearly?" Tonight, the rules of the entire giant city will be rewritten by a garbage man. And he in the future is waiting to kill his current self with his own hands.
