A cold wave swept through the mountains and forests, and the Silver Wolf tribe faced an existential crisis of food shortage. Lin Wan, who knew farming and was good at storing grain, unexpectedly broke into this primitive tribe and became the key to breaking through the predicament. She took potato seeds and farming wisdom and took root in the Yinlang tribe. While teaching the tribe to cultivate land and store food, she formed a deep bond with the tribe's warriors Yin Lie and Feng Yi.
From fighting Mo Lin, the leader of the Black Scale tribe who kidnapped her, to resolving the conflict between the two tribes and joining forces to fight against the blizzard; from accepting the homeless White Ear tribe, to the three tribes working together to reclaim farmland and celebrate the harvest, Lin Wan used kindness and wisdom to connect the scattered tribal forces, turning the cold winter into a warm time together. The waves of wheat in the fields, the bonfire in the wooden house, the hot porridge late at night, and the murmurings on the pillow not only bear witness to the survival and transformation of the primitive tribe, but also hide the deep love between Lin Wan, Yin Lie, and Feng Yi that spans ethnic groups and environments. When spring planting and autumn harvest became the agreement of the three tribes, and when protection and companionship integrated into every day and night, Lin Wan finally understood that this mountain forest that once frightened her had become an eternal home she had built with love and trust.
