Xunya, an exploration team member who understands Oroqen folk customs, went deep into the Saji Mansheng Mountain to explore for uranium deposits. Strange things happened one after another in the camp: the old captain died suddenly after the fire ceremony, and strange runes were left next to the body; shaman drumbeats were heard at night, and the instrument data disappeared the next day. Xunya discovered that all accidents were synchronized with violations of folk taboos, and the leaked intelligence accurately pointed to the progress of exploration.
He relied on the knowledge of the Oroqen people to investigate: predicting danger from the dryness and wetness of campfire ashes, using birch fire fungi to preserve key samples, and finding warning marks left by predecessors on the totems of Shaman Mountain. During the process, the seemingly amiable deputy captain Qi Mo was full of doubts - he was familiar with the sacrificial process but deliberately violated taboos, and always acted alone before data was stolen.
Seeking and setting up a trap: Pretending to leak the false news that "the core area of the uranium mine is under the altar of the god of fire", and at the same time holding a bonfire night ceremony according to folk customs. When Qi Mo sneaked into the altar late at night in an attempt to deliver information, the folk mechanism set up by Xun Ya was triggered - the bonfire triggered by rosin lit up specific patterns, illuminating his secret message to communicate with foreign forces. In the end, the inner ghost was caught, and Xunya also went through a complete fire sacrificial ceremony, gained recognition from the indigenous people, and protected the safety of the uranium mine and the camp.
