The old archaeologist Wang Jingshan received a mysterious map pointing to the Kunlun Forbidden Land, which is related to the legend of "Snake Bones and Buddha Sloughing". He teamed up with graduate Qin Xinran and guide Liu Yidao to explore the secrets. After going deep into the restricted area, the three of them experienced the life-and-death test of misty traces, numerous mechanisms, terrifying beasts and illusory light arrays, and discovered the lost underground city-state of the "Sun Eater" civilization. They were shocked to learn that the "Snake Bone Buddha Sloughing" is a cruel ritual that integrates with the consciousness of ancient earth veins, and often leads to failure, mutation or destruction.
On the way, they were pursued and plotted by well-equipped foreign competitors who coveted this power. Under their conspiracy, they were almost destroyed by internal strife due to the disappearance of the map. In the end, after breaking into the core of the earth's veins, Liu Yidao and Professor Wang died heroically one after another in order to stop their opponents and seal the "eyes" of evil consciousness caused by the failure of the ritual. Qin Xinran, who has a special resonance with the energy of snake bones, successfully purified/sealed the core crisis with the help of the key relic Snake Bone Dagger and the remaining will of his companions.
Qin Xinran, who escaped alone, suffered physical and mental changes and returned carrying a heavy secret. However, new clues indicate that the threat in the Forbidden Land is not really over, and that a greater crisis is quietly brewing elsewhere in the world.
