Lin Che awakened the S-level power "Time Merchant", but was sent to the Doomsday Reincarnation Sequence because she was too useless. At the beginning of the zombie siege, others were struggling to survive, but he set up a stall: "Sell one hour of safe time, and accept life span, memory, and soul fragments as payment!" While all the survivors were struggling for the next bite of bread, Lin Che had already used the "time" she had collected to exchange for Star Destroyer blueprints, and "memory" to exchange for mythical skills. Later, the reincarnations were horrified to find that this young man who looked like a profiteer was sitting leisurely at the top of all the apocalyptic worlds, smiling at the evil gods and the supreme system: "Guest, do you want to buy a timeline? The price... Is negotiable."
