After Tang Seng and his disciples returned from studying for Buddhist scriptures, they each lived a seemingly peaceful life. However, there is an undercurrent surging under the calm, and mysterious monsters appear and do many evil things. Sun Wukong summons Bajie and Sha Seng to investigate the origins of monsters and discovers that they are controlled by mysterious forces. Encountering a mysterious woman in the process, the four masters and apprentices gradually fell into trouble. During a battle, Sun Wukong accidentally discovered a mysterious jade pendant. He followed the clues to find the source - an ancient cave hidden in the mountains. He learned that the evil demon god was sealed here thousands of years ago. Now that the seal has been loosened and wants to be resurrected by the monster, the mysterious woman is his subordinate. Later, the demon god used a young man to successfully revive, and the world fell into a new crisis. Wukong was the first to notice the strangeness of the demon god's resurrection, and the four masters and disciples launched a final decisive battle with the tide of demon souls. Although it was extremely difficult, with faith and concerted efforts, they finally defeated the demon souls and protected the peace of the world.
