Lin Dongzhi, a medical student, never thought that he would go from being a student chewing on medical books to being a prodigy under the Changbai Mountains. Grandpa, a strange incident happened in the first seven nights of the old Monument King's life, forcing him to embark on the path of becoming a hero. When he moved the pole to set up a hall, the person who appeared was not the famous immortal family, but Bai Xian, the fox fairy whom Grandpa had suppressed for half his life. With the words "Give me back the end of my life", he was dragged into the abyss of the immortal family's grievances. He takes the talkative horse Huang Xiaopao and the clever snake fairy Chang Qingyu to break into the secret realm of Changbai, break the maze of the Immortal Family, and the soldiers and horses of the Huiyin Hall, and solve the mystery of the 30-year civil strife in the Immortal Sect; he not only has to fight against the developers who hired the head-dropping masters to steal the dragon veins, but also the Internet celebrity who made money from the immortal fate. Keep the Five Precepts in mind, and keep the Three Not Accepted and the Four Not Saved in your deeds. The secret of the two foxes in Grandpa's coffin, Bai Xian's true purpose, and the entanglement of three generations of stele kings are all hidden in the wind and snow of Changbai Mountain and the green smoke of the incense table. This is a two-way journey between the younger brother and the immortal family, and it is also the persistence and redemption of the traditional horse culture in the new era. The legend of the Changbai Mountain Monument King has since been written by Lin Dongzhi.
