On National Day in 1983, Xu You'an is reborn back to the age of twenty! Having his family ruined and destroyed in his past life, he awakens the Beast Taming System, contracting weasels, divine eagles, blue Tibetan mastiffs, and giant eagle owls to form a beast pet legion. He ventures into the mountains to hunt rare mountain delicacies and giant game, getting rich overnight to save his father and repay his debts, fiercely tearing apart the blood-sucking patriarchal family clan, and using beast pets to punish evil and protect his elder sister. Relying on his beast pets to rescue his niece from miles away, he annihilates a deep-mountain human trafficking gang, winning official commendation! He breaks the monopoly on game meat, deters vicious neighbors and bullies, and later rescues the female college student Shen Qingci in the Heishi Mountains, starting an even more passionate legend of mountain foraging!
