Tang Seng was captured by the monster, and the remaining Monkey King, Zhu Bajie and Sha Seng were arguing over a crisis of trust. For a while, the situation was very critical. It turned out that Sha Seng was a half-demon who had gone astray, but at the critical moment, he was enlightened by the Arhat who subdued dragons and tigers and returned to the right path. The Buddha gave Sha Seng a very important task, which was to secretly help the Western Star Monkey Monkey Sun Wukong. After some twists and turns, the three brothers finally resolved the misunderstanding and followed the clues to the different space. Here, the powerful Four Heavenly Kings of the Netherworld were waiting for them. Only by breaking through the Four Evil Palaces guarded by them could they break the barrier and rescue Tang Seng. However, Sha Seng and others who fought bravely to save their master did not know that they had fallen into a trap carefully set by the leader of the Tai Sui Special Forces.
