A 15-year-old Chinese boy, Shen Yizhou, obsessed with the legend of Tianchi, came to Changbai Mountain with his parents. Chasing a red-tailed tit, he mistakenly entered an undeveloped forest area, and suddenly encountered a whiteout blizzard, losing contact with his family. Cui Batou, who understands the ways of the mountain, led a ginseng-gathering team into the mountain through wind and snow to search and rescue. The secret realm slowly revealed itself through the wind and snow, as ancient trees and underground sacrificial halls emerged, and ginseng spirits and mirage dragons appeared one after another. The Zhaoshan Mirror left by his grandmother and ancient mountain ballads were the key to his homecoming in a desperate situation. A thrilling and magical adventure in the mountains and forests begins; the boy grows and transforms amidst crises, grasping the true meaning of awe for nature. This drama is an artistic fiction; please do not trespass into undeveloped areas of the reserve.
