Before Yun Shu was sold by her parents, she didn't even have a name, she was called Daya. She got the name because she worked as a maid at Xinglin Villa. Later, she met a monk who took her as his disciple and left her to roam in the mountains.
When I was sixteen years old, I was injured by my master. She went down the mountain and met Cheng Yuwan, the heroine in the painting book, and had a conflict.
Only then did she realize that she was just a small character living in the world of picture books, a passerby without a plot.
Cheng Yuwan always wanted her to die because Yun Shu ruined the plot, so of course Yun Shu had to fight back.
Counterattack after counterattack, she rose to become the biggest villain.
The world thought that she was able to defeat Cheng Yuwan again and again because of her high talent in cultivation, but she was just an experiment for her master.
