"The Wild Monkey" is a humorous adventure novel that combines Eastern mythology and American western pioneering. The story begins in 1875. Sun Wukong, who had completed the study of scriptures from the West, lost control of his experiment in heaven. He traveled to the Wild West with the white dragon horse Zhui Feng, and his magic power was greatly reduced. In order to make a living and find a way to return home, Sun Wukong transformed into the bounty hunter "Big Dart Monkey" to punish rape and eliminate evil in Tombstone Town. He successively met Tang Seng who preached, Zhu Bajie who opened a tavern, and Sha Seng who worked as a miner, and the master and apprentice reorganized the team.
The West is not peaceful: the legendary bandit leader Jesse James colludes with the Eastern monster Black Wind Laoyao to compete for the "Five Elements Mine" that contains the energy of time travel. As the investigation deepens, the conspiracy of the mastermind behind the scenes comes to light - this ancient demon intends to collect the Five Elements Mines, open the rift in time and space, and conquer the Eastern and Western worlds at the same time. Sun Wukong has to join forces with Sheriff Reed, Chief Sitting Bull, Billy the Kid and other western allies to launch an ultimate showdown that spans myth and reality.
The novel uses intensive complaints and the collision of Eastern and Western cultures to create jokes: the Great Sage Monkey King uses a revolver, Monk Tang uses Buddhism to influence cowboys, Bajie wants to open a tavern into a chain store... Under the humorous tone, it explores belonging, justice and growth. In the end, Sun Wukong faces a choice: return to Huaguo Mountain, or stay in the west, which has become his second home, and become the "Big Dart Monkey" who protects the legend.
