During a famine year, hunter Xu Shanhe was tricked by his own mother and elder brother into the deep mountains and abandoned, dying at the Mass Grave Ridge. Waking up again, he unexpectedly was reborn as a large yellow dog guarding by his wife and daughter's side, and acquired the Mountain Lord's inheritance. Unable to speak and recognize each other, Xu Shanhe could only protect Su Maisui and his daughter in a dog's body, leading them to dig arrowroot, hunt wild game, seek medicinal herbs, and survive the famine, while also uniting with villagers to form a hunting team to fight against greedy relatives and poaching gangs. As the five Mountain Lord spiritual patterns gradually gathered, his wife finally recognized his true identity. In the end, Xu Shanhe completed his inheritance, reshaped his human body, reunited with his wife and daughter, and also led Shilinggou out of famine.
