The seven princes in heaven had to go through tribulations of mortal love before they could become immortals. Their souls joined the world of "The Return of the Princess" and incarnated as Yongqi, Erkang and other seven people. Their memories were sealed and only the instinctive ties to the destined people were preserved. In order to protect their loved ones, the seven fairies also transformed into women such as Xiaoyanzi and Ziwei. They carried spiritual stone tokens to accompany them, abiding by the rules of heaven and not revealing the magical secrets.
King Yin Eclipse colluded with Xinrong to cause chaos, using the palace's suspicions and the secrets of his life experience to stir up resentment, in an attempt to destroy the foundation of the prince's experience. Broom Star was ordered by the Emperor of Heaven to transform into a Taoist priest. He secretly resolved crises many times and became an invisible protector.
Everyone has experienced disasters such as Hanxiang entering the palace and Ziwei recognizing her relatives, and their celestial destiny has gradually awakened: Yongqi (Yu Ri) protects Xiao Yanzi (Lv'er) with his mechanical skills, Erkang (Dong Yong) sacrifices his life to protect each other for Ziwei (Zi'er), and Xiao Jian (Liu Yixuan) and Qing'er (Lan'er) are attracted by their jade pendants. At the final ceremony to sacrifice to the heaven, everyone's memories were restored, and the "Seven Star Evil Exorcism Formation" was deployed to suppress the Yin Eclipse King, and he was happy and repented.
During the journey, seven couples finally got married and stayed in love with each other after their wedding. Ziwei, Xiaoyanzi, and Qing'er all became pregnant with twins three times. When Xiaoyanzi gave birth, auspicious clouds descended from the sky and hundreds of birds chirped, and the eldest son was named Mingye.
Many years later, Yongqi relied on her resourcefulness and responsibility to gain a firm foothold in the court, and eventually became the supreme ruler, working hard to govern and protect the party. Liu Qing (God of Cookery) runs the restaurant with great success, Mai Erdan (Ma Tianlong) and Han Xiang (Qing'er) retreat to the Western Regions, and the other couples are also happy. After their mortal mission was completed, the seven immortal couples returned to heaven with their children. They were all granted the title of immortals and continued their bond for thousands of years.
