Gu Xiaoman, who possesses the soul of an adult, is reborn overnight as an infant in swaddling clothes. By a twist of fate, she falls into the wolf den of Langlang Mountain and is rescued and adopted by the fierce yet soft-hearted mother wolf Xue Lan. The outwardly soft, clueless "potato cub" has a mature inner mind and also commands a special ability to stimulate plant growth. She grows up under the protection of the pack, treating the wolves as family, and Xue Lan also regards her as her own cub, sparing no effort to keep her safe. The mountains and forests are fraught with danger, with beast battles and human explorers arriving one after another.
