The Dark Frost Season descends, the flames go out, and the entire tribe is on the verge of freezing to death. Zhu Qi, a transmigrator, is tied to the sacrificial altar. With his life hanging by a thread, he uses ice as a mirror and borrows the sun's light to make fire, turning the tide and becoming the settlement's new chief. Eighty-one people, forty jin of dried meat, and a long, bitter winter: he leads the primitive tribespeople in breaking through the ice to fish and hunting beasts to survive. Demons and monsters roam the Northern Wasteland, and humanity is as insignificant as grass. But he will make the flame burn again.
