Qin Jiuyou, lord of all demons, was cast into reincarnation by the God King’s sacrifice during the final battle between gods and demons. When he awoke, he had become Qin Ling, a bullied boy in a high-martial-arts city. His parents were weak, his younger sister was critically ill, and he was drowning in debt. At the brink of despair, the [Abyss Sign-In System] awakened! Sign in at the toilet where he was bullied and receive the [Indestructible Demonic Heart]! Sign in at his gravely ill sister’s bedside and receive the demonic tome [Life Devourer]! Sign in at an underground boxing ring and receive the [Asura Battle Spirit]! Qin Ling smiled. If this hypocritical light cannot accept me, then I’ll return to the abyss and make this world hear the name Qin Jiuyou once more!
