Toy Sun Wuyuan thinks he is the Monkey King, but he is ridiculed in the toy world because he can't get the gold hoop stick. By coincidence, Sun Wuyuan entered the world by himself and was occasionally driven back to Huaguo Mountain by Sun Wukong. Sun Wukong had no choice but to put forward the condition that Sun Wuyuan should worship him as a teacher and give him the Golden hoop stick after he had learned it. Unexpectedly, the Devil of the Ox secretly provoked and abetted the five yuan to steal the gold hoop stick and take it away. Running back to the toy world in a hurry, the five yuan discovers that the world has been ruled by cattle.
