At the Beginning, the Demon Lord Was Integrated, and the First Sword Was Slashed at Tianjiao.

[Urban High Martial Arts] + [System] + [Sign In] + [Demon God] + [Decisive Killing] + [Sister Control] + [Pretend to Be a Pig and Eat a Tiger] + [Invincible Flow] Qin Jiuyou, the lord of all demons, was sacrificed by the god king in the final battle between gods and demons and sent into reincarnation. When he woke up, he was Qin Ling, a bullied young man in the high-tech city. His parents are weak, his sister is critically ill, and he is heavily in debt. In times of despair, [Abyss Sign-in System] awakens! Sign in in the toilet where you were bullied and you will be rewarded with [Immortal Demonic Heart]! Sign in at the bedside of your seriously ill sister and you will be rewarded with the [Life Deprivation] magic book! Sign in at the underground black boxing arena and be rewarded with [Shura Fighting Spirit]! Qin Ling smiled. Since this hypocritical light cannot tolerate me, then I will return to the abyss and let this world hear my name, Qin Jiuyou again!
