When Shen Mo was collecting scraps in a village in the city, he picked up a black cube that could travel through the heavens. The first time he traveled through time, he was almost shot through the head by a battlefield arrow. Others relied on the system to get through quickly, but he relied on collecting rags to get through quickly - exchanging scrap metal for martial arts secrets, using old batteries for interstellar technology, and using a cart of plastic bottles to exchange a storage ring with the immortal cultivator. While other time travelers were busy attacking the heroine, Shen Mo squatted on the edge of the battlefield, pulling out the still usable energy cores from the pile of dead people.
