Forest ranger Zhu Qingfeng rescues a hungry tiger cub with a disabled hind leg while patrolling the mountain, beginning a lively mountain forest life. Relying on system points, herbal medicine, and sincere care for animals, tiger cubs, giant pandas, golden eagles, beavers, hedgehogs, pangolins, wild boars, tigress mothers, and others appear one after another. Along the way rescuing cute beasts, fighting poachers, and protecting the forest, he also turns the desolate small courtyard into the most reassuring home for the animals.
