Chen Shang's world shattered completely on that silent night in the convenience store. A doctor who could not save his own loved ones, he was forced to sign a devil's contract: a System called the "Price Balance" took root inside him, letting him wage war on the uncanny by paying with his flesh and blood. His fingers, his eyesight, his memories... Everything he owns comes with a clearly marked price. When the evil god "The Tailor," who sews together countless corpses, lists him as a collectible, and the official organization "Night's Watch" sees him as a high-risk bomb, Chen Shang grips his right hand as it continues to disappear, trapped between them. He gradually realizes that in this mad world, for a mortal to slay a god, he must first forge himself into a blade. Every payment is a sacrifice that takes him one step closer to the abyss, and also a spear hurled toward the divine throne. This is a desperate gamble that begins in despair and ends in destruction. The day his body is covered in wounds will be the day a mortal cuts down a god.
