In 1938, war broke out, Liu County, Liuzhou was calm on the surface, but the undercurrent was turbulent. The fortune teller wanders around the market indiscriminately, looking like a charlatan, but in fact he is a strange man with extraordinary skills. When he first arrived in Pujiangwei, he met Mr. Wei, a country doctor, and was involved in a mystery: in the Shiwan Mountains, the Japanese army made a detour and made a surprise attack. A battalion of soldiers under Governor Yang Hong disappeared mysteriously, and the only remaining madman was saved by Zhang Si's spell. In order to find out the truth, Zhang Si was forced to join forces with Shuangqing squad leader Lin Tianshui, warlord Yang Hong and chamber of commerce wealthy businessman He Ziying to embark on a dangerous journey.
The deep mountain is filled with miasma, and the strange sound of the flute attracts a group of beasts to attack, seemingly controlled by a "mountain god". Zhang Si speculated that this was caused by a mandrill, but suspected that there was another mastermind behind the scenes. In order to survive in danger, everyone turned to the underground gambling house to search for clues, and played a game with Zhou Jinhong, a master of thousands of arts, which involved a secret connection between the smuggling force and the God Team. Gambling, gun battles, and human calculations intertwined He Ziying's northwest trade routes, Yang Hong's military stance, and Lin Tianshui's Jianghu background, and Zhang Si's past—the Chongqing prison robbery and old debts owed to his life—also surfaced.
The fog in Shiwandashan has not yet cleared, the Japanese landing is imminent, and the torrent of the times is carrying all living beings. Can Zhang Si and his party uncover the mystery of the missing soldiers? Behind the mysterious flute and mandrill, is it a man-made conspiracy or a supernatural force? In troubled times, loyalty and betrayal, survival and morality are all uncertain.
