The story takes place in a parallel world where the demon world and the god world coexist. The demon girl Xue Diexuan, along with her maid and Shan Jingzi, came to Tianqing Mountain to become a disciple for some reason. Here they met an ascetic master who could live forever, a naughty and infatuated younger brother, and others. When she wanted to accompany the master for the rest of her life, the master passed away because of herself. Xue Diexuan was disheartened and planned to go down the mountain to try her luck. However, she met her younger brother Ximen Yufeng and was told that she could find all seven-color crystal stones to resurrect her master, so she embarked on the road to find crystals. Unexpectedly, there are many obstacles in the future. The former personal maid turned out to be an enemy spy; the reclusive old Dragon King turned out to be his biological father; the handsome guy from the God Clan who he was obsessed with turned out to be close to him just to fight for power or something... In the end, he succeeded in cultivation and collected all the crystal stones, but found that his master could not survive, and everything was just Ximen Bu's plan. After learning everything, Xue Diexuan was heartbroken and decided to abandon everything, only wishing to return to Tianqing Mountain and guard her master's soul for the rest of her life...
