Ling Qinghan was originally the supreme genius of the Lingyun Immortal Sect, but in fact he was the descendant of the ancient nine-tailed fox from Qingqiu. The bloodline of the young fox clan was forcibly sealed by his biological mother, and he was able to transform into a human with pure spiritual roots and hide in the Immortal Sect to avoid trouble. Taoist companion Ji Lingxiao and best friend Yin Suni have long been aware of her demon origin. The two of them teamed up to plot to destroy the spiritual roots and extract the immortal bones. They were not just jealous, but were ordered by the corrupt immortal way to kill Qingqiu's last bloodline and use her fox clan's reincarnation power to refine immortality. The abandoned Nine Nether Reincarnation Tower was the secret trial realm created by the ancient Nine-tailed Fox Ancestor before his death. Eight hundred years of endless dungeon fighting in the tower is both a purgatory and a furnace for bloodline unsealing. In countless reincarnations of life and death, Ling Qinghan awakened the fox clan's natal magical power, Karma Fire Reincarnation Eye, and the nine fox tails gradually recovered after clearing the dungeon and settling the karma.
The Immortal Sect's method of detecting spirits could not detect the physique of the demon clan, so she took advantage of the situation and disguised herself as a useless person, hiding in the labor yard, and started on the road of pretending to be a pig and eating the tiger. With the experience of three thousand small worlds and the power of the nine-tailed karma fire in her hands, she coldly tore apart the dark secret of Lingyun Immortal Sect's ability to refine immortality with the flesh and blood of all people and monsters. The phenomenon of the Tower of Reincarnation spreads, the dungeon rift invades reality, and the hypocritical masks of the former betrayers are shattered layer by layer. She disdains to regain the glory of the Immortal Dao. She is burdened with the blood sea of Qingqiu's genocide and the hatred of eight hundred years of purgatory. She uses the nine-tailed karma fire as a blade and the law of reincarnation as a punishment to liquidate her enemies step by step. She vows to overthrow the hypocritical way of heaven, slaughter the Numb Immortal Sect, and let all the powerful Immortal Dao who slaughter demons and trample on living beings sink into reincarnation and be buried with the souls of Qingqiu and thousands of innocent souls.
