The earth was once a spiritual world filled with spiritual energy. Two thousand years ago, a "War between Immortals and Demons" penetrated the spiritual veins of heaven and earth, and nine "void abyss" were formed at the breaks of the nine main spiritual veins. The abyss erupts once every three hundred years with a "spiritual erosion tide". Wherever the tide passes, spiritual energy is corroded into "erosive energy". Monks who are exposed to it will collapse their cultivation, and mortals who are exposed to it will go crazy and die.
In order to suppress the abyss, practitioners of all ages used "immortal veins as locks and souls as keys" to cultivate themselves layer by layer into the cracks of the abyss. Each of the "Zhenyuan people" could not live to be five hundred years old - the physical body became part of the seal, and the soul was trapped in the abyss and suffered from the corrosion day and night.
The previous Zhenyuan person was "Xuanqing Immortal", and she guarded the Ninth Abyss for three hundred years. For three hundred years, she raised a baby girl by herself, named Su Mian, and lived on the top of an unknown mountain, isolated from the world.
Three hundred years later, Xuanqing Immortal Lord passed away. Su Mian held her token and went down the mountain.
Under the mountain is a world that is completely unfamiliar to her: high-rise buildings, mobile phones, scan-code payment, hot search lists, and milk tea shops. The "senior brother Shen Du" she is looking for is the richest man in Jiangnan City, and he is troubled by the "haunting" of his company's servers.
What she didn't know was that she was a "living seal" created artificially. Her master, her sister in the previous life, spent three hundred years making up a gentle lie - making Su Mian think that she was "saving the world", but actually she was "protecting Su Mian from being found by the Lord of the Abyss".
The Lord of the Abyss slaughtered half of the fairy mountain for a mortal woman three hundred years ago. That woman was Su Mian's previous life.
