In order to repay online loans, Han Gan, Liu Yun and Sun Hao broke into the entrance of the Three Realms of Western Yunnan. They wanted to find some antiquities in exchange for money, but unexpectedly ran into a giant red-crowned snake and a strange stone statue. By accident, they discovered a hidden compartment under the stone statue, and became involved in a secret that spanned thousands of years - a fictional royal tomb during the Southern and Northern Dynasties was hidden in the mountain. The giant snake was actually the beast guarding the tomb. The villagers of Heiyan Village lived with snakes and sacrificed human beings to the "snake mother".
From the burial bronze tripod in the ancient cemetery palace to the miasma enchantment formation in the primitive jungle, the three of them must avoid the pursuit of the corpse-turned-master of the royal tomb, the piranha and the heel-footed beast, and also expose the conspiracy of the Snake Village. The jade juke, the bronze tripod and the broken map connect clues together, and every step is on the edge of life and death. Deep in the Three Realms Pass, there seems to be a more terrifying truth waiting in the fog.
