Like a dream, the Buddha sat down on the bodhi tree, attained enlightenment and transformed into a human form. The Queen Mother held a banquet. After getting drunk, Yue Lao accidentally threw out the red thread, which entangled Rumeng and others. The Buddha sighed and was about to give up on Rumeng, but because of the love between master and disciple and the way of Buddhism, he allowed her to break the red thread in the mortal world and return to sit down. Rumeng has gone through many lives in the mortal world and finally reached the last red thread. She was born into a farmer's family in this life, and she also has a younger sister - her mirror-like double. When Rumeng was ten years old, the village was attacked by bandits. She escaped with her younger sister and was recruited as a disciple by Sikong Yuan, a Taoist priest of Xuanmen, who devoted herself to practicing Xuanmen arts. One day, Yuan Zheng led her into the painting, but she didn't want Yuan Zheng to be trapped in the painting. Many years later, Rumeng got a painting by chance and entered the painting again. Rumeng saw Si Xie who was sealed in the painting. Because of Si Xie's help, the painting was released, and Si Xie could freely enter and exit the painting.
