Shen Mian is the useless young master of the Yunlei Demon Clan who cannot awaken the demonic veins. He is regarded as useless by his tribe and thrown into the extremely dangerous Emperor Thorn Cage. During the long days, only his close friends Lu Ge and the demon dragon Akao were by his side to accompany him through the endless difficult years.
Something happened suddenly, and fate cruelly took away his only warmth and light. Lu Ge unfortunately died to protect him. When he was dying, he only hoped that he would become a unique demon king in the future. Shen Mian, who was extremely grieved, chose to self-destruct the demon core and kill the enemy with his hands, and then struggled to break through the demonic barrier with the help of Akao.
On the verge of death, Judge Li Jiuyan of Mingchuan offered him a deal: as long as he sneaked into the Zhengdao Sect and acted as an undercover agent, he would help him resurrect his dead friend. In order to see her old friend again, Shen Mian resolutely entered the game. He only wanted to fulfill the agreement perfunctorily, but unexpectedly he met his senior brother here who was always targeting him. From then on, the two became entangled, and in the end they formed a life-and-death bond that was difficult to break away from.
