When Li Entropy climbed out of the pile of corpses in the underground black market, his memory was only blood and fire. He can devour other people's powers, but can no longer remember who he is. Chu Xiao, once the deadliest scavenger in the black market, now wears a human skin mask and hides in the dark, just waiting for someone who can avenge him. When the rules of the black market collapse, living people become commodities, and people with supernatural powers become prey. The two meet again in the blood alley - one wants to tear this hell apart, and the other wants to burn all the truth. They are not allies, but they can only go into the abyss together. No one knows that Li Entropy's erased childhood is hidden under Chu Xiao's blade.
