As a result, she accidentally broke a bunch of red threads. In order to make up for her fault, she stayed in Yue Lao Palace to repair the red threads with Yue Lao's only apprentice, Yue Hua Xianjun. During this period, Yue Hua gradually understood Xiaoyu develops feelings. At the same time, Dongxu Shangshen, the son of the sun who has experienced calamity in the human world, accidentally gets married to Xiaoyu, who travels to the world through the Universe Mirror to repair their marriage. In order to recover his little daughter-in-law, he will be found wherever there is Xiaoyu, regardless of the human world, the demon world or the fairy world.
