Su Wanxing, the reincarnation of the Moon Soul Flower, went to find "Mr. Cloud" Yun Xuanci and became a disciple of Yunhe Peak in Cangwu Mountain. Little did he know that he had a "Heart-Eating Curse" due to the "Heart-Eating Curse" received by the spirit who protected the flower three hundred years ago, and he began to eat his heart when he was in love. The master and disciple hide warmth in their daily lives: guarding the sick on snowy nights and guarding against danger in secret realms, but the truth is also revealed due to the Xuanyin Sect's conspiracy. Finally, on the night of Chinese Valentine's Day, the two used their heart's blood and the power of flower spirits to break the curse and hold a wedding banquet in a flower setting. The days after the marriage were full of fireworks: they made herbal ointments together, helped the world save rice fields, raised flower seedlings "from morning to night", and even recorded every detail in "Yunhefeng Ji", turning three hundred years of waiting into a warm and loving relationship.
