The heroine in the previous life was not named Yiyi. She was not a carefree little Yimi flower demon who walked out of the desert, but a little pearl in the sea. Although she had also cultivated into a human form, she met the dragon, Mr. Mo Sang, by chance. The little pearl was lucky enough to save Mo Sang's life, and later became a lover with Mo Sang. Later, Mo Sang was hurt by someone and his heart was broken. Little Pearl had to do her best. In order to repair Mo Sang's heart, both body and soul were destroyed. Mo Sang had no choice but to put the last bit of life of Little Pearl into the Yimi flower in the desert to save her, while he built a Mingyue Tower on the Mingyue Sea to wait for her return, and placed the key to the Mingyue Sea on Yiyi. The story unfolds slowly.
