This story is a derivative novel based on the platform of "The Patriarch of the Demonic Way" and can be read as an extra.
One day, a little demon wolf broke into the Cloud Recesses. Why didn't the mountain protection barrier work? After investigating, Lan Wangji and Wei Wuxian discovered that the little demon wolf actually had a jade plaque from the Gusu Lan Sect hanging around his neck, as well as a small bamboo tube. The jade plaque turned out to be a jade plaque made two hundred years ago and used by the direct relatives of the Gusu Lan family. It was engraved with the word "spirit" and a small note written "Save me" was attached to the bamboo tube. So Wangxian took Lan SiZhui, Lan JingYi and the Ghost General, the juniors of the Lan family, on a night hunt, embarking on a journey to rescue their ancestors and uncover the mystery of their ancestors' history two hundred years ago.
Lan Ling'er is the youngest of five brothers and sisters in the fifth generation of the Gusu Lan family. This aunt of the Lan family is extremely talented and has strong spiritual power. She debuted at the age of thirteen. She is invincible in slaying demons and demons. She has rescued countless villagers and is regarded as the "Gusu Saint." At that time, the demon clan was powerful, and a large number of little demons swarmed into the human world to do evil, causing all life to be ruined. In order to save the common people, Lan Ling'er used herself as bait to lure the demons back to the demon world, and sealed them with a powerful barrier. This barrier could only be entered but not exited, so the words "died at the age of twenty-five" were recorded in the annals of ancestors. But why does the jade plaque belonging to Lan Linger appear here after disappearing for more than two hundred years?
When Hua Rong was seven years old, she was rescued by Lan Ling'er by chance and became a disciple of the Gusu Lan Sect. She stayed with this aunt of the Lan Sect until she was sixteen years old. For some reason, she became a demon and destroyed the Immortal Sword Sect, the largest sect in the world of cultivation at that time, and was expelled from the Gusu Lan Sect.

Concept: The distinction between good and evil in the world is difficult to define. There are bad people and good monsters. Just like becoming a demon does not necessarily mean you become a bad person, becoming a demon can also save the common people.
