Ye Wuchen, who was once the humblest servant disciple of the sect, unexpectedly awakened due to the "mad bloodline" that had been dormant for thousands of years in his body. He stained the trial stage with blood overnight, beheaded the elders, and was wanted by the entire sect. He didn't know that he was the reincarnation of an ancient demon god, nor did he know that the awakening of his bloodline would cause turmoil in the nine realms. In order to find out the mystery of his life experience, he stepped out of the sect and formed an alliance with the mysterious female assassin Su Liyue - she possesses the art of sealing, but is devoured by nightmares every night because she is the descendant of the saint who sealed the demon with her own hands. As the blood rage intensified, Ye Wuchen began to lose his mind, and Su Liyue's sealing power actually resonated with his blood. Destruction or redemption? The gate to the Nine Realms is about to open, and the real enemy is hidden in their most trusted memories.
