More than a thousand years ago, the sweet-osmanthus god Tongxiang, the princess of the divine world, fell in love with the water god Huanxi. However, the queen mother did not allow it, and the sweet-osmanthus flower god was demoted to the mortal world and suffered the pain of reincarnation. The Queen Mother ordered the Tantai family that whenever they encounter these two people, they must be separated. If you let them go out of compassion, you will be punished by genocide. Therefore, the Tantai family has been looking for the reincarnation of Princess Tongxian for more than a thousand years to prevent her from meeting the water god again. Princess Tongxun was reincarnated as Xiahou Tingxi, the only daughter of Xiahou Yanyuan, the richest man in the capital. The water god declared himself isolated in Changling City, and Tantai Zhi, the son of the current head of the Tantai family, Tantai Zhi, was the artifact of Princess Tongxun. In the end, he sacrificed himself in order to fulfill the thousand-year love between Princess Tongxun and the water god, and chose to be destroyed.
