Tianchi in Changbai Mountain is the skylight leading to Guixu and the source of the eight-hundred-year immortality curse of the Eastern Xia Kingdom. Meteorites from outside the sky can grant people a life span of 320 years, but they will rewrite genes and cause underground civilization to perish in aberrations - longevity against the will of heaven, all at the cost of death.
In order to explore the mystery of the water source of Tianchi, the Yanjing University scientific expedition team went deep into the uninhabited land of Changbai Mountain and unexpectedly stepped into this mystery of immortality. Thunderstorms lock the mountain, the compass reverses, the human-faced crickets laugh ferociously, and the ghost tree vines kill people. Under the stone tablet of "not of my kind", there is a fatal warning of "whoever enters, will live forever."
Lin Hao, who carries his family's "Book of Enlightenment", is forced to face the unknown. The gentle and elegant Li Mingyuan is actually a descendant of the Eastern Xia survivors. Special operations veteran Chen Ye is investigating the truth behind the tragic death of his comrades. The charming Zhao Wan is a descendant of a traitor, but is used as a pawn by his family.
The Guixu Bead on the head of the Tianchi water monster, the glowing crystal core deep in the cave, the ancient beasts guarding the meteorites, and the traitor forces that are pressing every step of the way, push the scientific expedition team into a desperate situation. When the lie of immortality is exposed, will they flock together, or work together to end this eight-hundred-year-old curse? The gate to the ruins is open and no one can escape.
