The Longevity Monk has been captured by a demon, and the remaining Monkey King, Piggy, and Monk Sha are in a critical situation as they are arguing over a crisis of trust. It turns out that Monk Sha was once a half-demon who went astray, but in the nick of time, he was enlightened by the Dragon Subduing and Tiger Fighting Lohan and returned to the right path. Buddha gave a very important task to Monk Sha, which was to secretly help the Monkey King, the Monkey King, the Star of the West.
