The novel revolves around the love-hate entanglement and sacrifice of a pair of lovers in three reincarnations.
In the first life, she was Feng Qiwu, the leader of an ancient tribe who guarded one side, strong and lonely; he was Xiao Yao, a wandering Taoist priest who was carefree in the world, romantic and uninhibited. In order to seal the World-Destroying Demon Lord, Xiao Yao had to sacrifice the soul of his beloved with his destiny bloodline as the center of his formation. He stabbed her in the heart with a fatal blow and swore with tears: "If there is an afterlife, I, Xiao Yao, will definitely live up to you."
In the second life, she was the most popular disciple of the Immortal Sect, while he was an unruly and unruly cultivator. The demon king's seal is loosened, catastrophe strikes again, and she has the destiny to repair the seal. She calculated all the secrets, but she couldn't figure out her own heart. In the end, she set up a trap to lure him into the battle, and using his pure love as a guide, she sacrificed him and completed her mission. She cried and swore: "If there is an afterlife, I will protect you and never let you go."
In the third life, they both became mortals and forgot their past lives, but they still fell hopelessly in love with each other. When the Demon King completely broke the seal and the world was on the verge of destruction, their remaining memories were awakened. This time, they finally understood that the power of "love" between the two of them was the only way to purify the Demon Lord. They no longer chose to sacrifice one of them, but walked into the center of destruction hand in hand, and both died in the embrace. They exchanged eternal death for life, and fulfilled their vow to never be separated from each other.
