"Journey to the West: System Era" reconstructs the classic Journey to the West narrative. Tang Monk uses the "merit system" to bind Buddhist promotion tasks, Wukong uses the "Combat Power Analysis System" to explore the key to breaking the tight hoop, Bajie uses the "Desire Exchange System" to secretly investigate the secret of the flat peach in heaven, and Sha Monk relies on the "Cause and Effect Liquidation System" to trace the sinful debt of Liusha River. The four of them all knew the script of the 81st Incident, but they had their own obsessions due to the system information being blocked. From testing each other when they first met at Wuxing Mountain, to Gao Laozhuang seeing through the truth that "the system is actually a chess piece of the three world bosses", they gradually formed a disobedient alliance.
They reversely used the disaster nodes: three dozen white-bone spirits exposed the Buddhist control, three-tune the banana fan to rescue the red boy and confront Guanyin, Shituoling teamed up with the Taoist sect to defeat the Dapeng, and finally revealed that the essence of the system was the "destiny program" left by Pangu, and the Buddha and Tao were only the program administrators. In the final chapter of 81 Dilemma, the master and apprentice used their original combat power and faith in the Three Realms to reprogram the program, smash the formatted conspiracy, and allow the creatures in the Three Realms to gain their own destiny. They turned the path of learning into a counterattack from "chess pieces" to "chess players", opening a new era of freedom and sustainability in the Three Realms.
