Adapted from the game "Meeting the Dragon" by Orange Light, it tells the love story of the Dragon King and a little maid for three lives and three worlds. Liuying (played by Zhu Xudan) is a little maid next to Xiahou Xue. She accidentally encountered a snake and was almost scared to death. Liuying quickly caught the snake, but she didn't know that the snake was a Yinglong who had practiced for thousands of years, named Yuchi Longyan (played by Wang Hedi). Yuchi Longyan took Liuying away to repay her gratitude, but by mistake, Xiahou Xue, who cared about Liuying, mistakenly thought that she was missing. On the way to find her, she encountered a wolf demon and finally died accidentally in the hands of Yuchi Longyan. Yuchi Longyan fulfilled Liuying's wish, rescued the lady and protected her for three lives. In this way, Yuchi Longyan fulfilled his promise while privately protecting Liuying for life after life. It was not until the fourth life, Gu Qingyan, that he knew the existence of Yuchi Longyan. In order to save Yuchi Longyan who was punished by the Heavenly Rule, his soul was absorbed by the Fate Star Lord. In the end, the other half of his soul merged with Yuchi Longyan, helping Yuchi Longyan defeat the villain.
