At the end of the war between immortals and demons, gunpowder smoke fills the air, and destiny comes to an end. Su Mengyao slowly took back the whip in her hand, seeing through the entanglement and misunderstandings of three generations, she became coldhearted and decided to die on her own initiative. The moment she passed away, a ray of light suddenly enveloped Chu Yichen, dragging him into the reincarnation of time, and looking back in flashbacks to the first three lives of their fateful entanglement.
In the first life of the human dynasty, Su Mengyao was the female general galloping on the battlefield, and Chu Yichen was the bodyguard who never left her side. Love secretly arose, and the world was troubled. In the end, the bodyguard died to protect the general and defended him with his life.
In the second life, the two entered the Immortal Sect together and became Taoist disciples. They practiced together and their love was deeply rooted. When danger comes, Chu Yichen is seriously injured in order to save Su Mengyao. Only the sacred objects of the demon world can save his life, and the only way is to transform into a demon king. He endured the pain to absorb the holy object, but his fate suddenly reversed. Instead of falling into the devil's path, he overcame the tribulation and ascended to the immortal class.
In this life of reincarnation, Su Mengyao was reincarnated as a demon king, carrying with him the complete memories of his two lives. She clearly remembered his sacrifice in protecting him in his two lives, but she did not understand his choice to ascend to immortality, and mistakenly thought that he had betrayed his love for the sake of the great road. But Chu Yichen lost all memories of his past life and only recognized the different paths of immortals and demons.
One person is full of obsessions and grievances, and the other is ignorant of the confrontation between good and evil. Misplaced memories and contradictory positions lead to layer upon layer of misunderstandings, entangled love and hate, and ultimately lead to the tragic ending of the battle between immortals and demons, leaving three lifetimes of regrets and a fate that is hard to break.
