Baishi Village hunter Zhou Qingshan devoted his life to filial piety towards his parents and supporting his eldest brother, giving all the game he worked hard to hunt to the Zhou family, while ignoring his wife and daughter. During a hunting trip into the mountain, Zhou Qingshan tragically died deep in the mountains. Waking up again, he unexpectedly was reborn as his family's domestic mongrel dog Dahai, and obtained the Mountain God's inheritance. As long as he devours spiritual objects in the mountain, he can gain abilities, eventually transforming into a human and becoming the mountain-guarding divine beast. Reborn and returning, Zhou Qingshan saw his family turn hostile and mercilessly drive his helpless wife and daughter out of the house. Filled with regret, he vowed that what he failed to protect in his past life, even if he is just a dog in this life, he will never let them suffer again. From then on, Zhou Qingshan began the path of gathering mountain treasures to get rich.
