There is a fairy mountain outside the world of Shenzhou, named Fengyun. On top of the fairy mountain is the Xuanzong lineage, which has guarded the spirit of Shenzhou for generations and protected Shenzhou from being disturbed by evil spirits and treachery.
A hundred years ago, a great battle severely damaged Xuanzong's vitality. The evil demon sneaked into Xuanzong's interior, took the opportunity to lure away the two elders, and transformed into a substitute to severely damage Xuanzong's vein-protecting and demon-sealing formation from the inside out. In the end, the war ended with both sides hurting, and the evil demon was completely isolated. The sect leader died, among the ten elders of Liuxian Siqi, one died, one suffered from demonization, two lost their bodies, three were seriously injured and fell into coma. Daozi suffered countless casualties.
Now, a hundred years later, Xuanzong, after a long period of recuperation, is at a time when everything is in ruins and waiting to be revitalized.
