Era: Starting from When the Forest Rangers in the Mountains Started Eating Meat.

In 1978, deep in the Qinling Mountains, a down-and-out young man named Lin Hai voluntarily applied to work as a ranger in the inaccessible Qingsong Ridge due to family changes. The villagers all thought he was going to die, but Lin Hai took the "Mountain God Cave Sky" with him. Heavy snow has sealed the mountains, and the villagers are starving and chewing tree bark. Lin Hai eats roasted sheep and drinks Fenjiu in the underground shelter. The most beautiful intellectual, Liu Wanqing, got lost in a snowstorm and fell in front of a wooden house. Lin Hai handed her a bowl of hot chicken soup. From then on, she began the journey of building a paradise in the depths of the mountains, subduing ferocious beasts, and fighting against external forces.
