The male protagonist Lin Ye, who comes from a declining beast-controlling family, was ridiculed for contracting a spirit fox, which was regarded as a "trash" by the world. On the surface, he is cynical, but in fact, with wisdom and strategy far beyond ordinary people, he has maximized the potential of the "waste" spirit fox, and embarked on a path to control the beast by outsmarting and subverting traditional perceptions. On the way, he met Yun Shang, a peerless pharmacist with a mysterious life experience. The two worked together to explore ancient ruins, conquer legendary mythical creatures, and compete for rare resources. Lin Ye single-handedly fought against clan oppression, imperial conspiracy, and the darkness from ancient times, and finally uncovered the ultimate secret of "Ling Yu". He grew from an underappreciated little person to a legend who truly defines the word "Beast Tamer".
