The journey of the Tang Monk and his disciples takes a dramatic turn as they arrive in the Black Rooster Kingdom. The core of the conflict centers on the revelation that the current ruler is an "evil Taoist" rather than the true sovereign. The Tang Monk initiates this confrontation by revealing his identity and mission—traveling to the "western paradise to get scriptures from Buddha." To prove his claims, he presents a "jade coin," a "royal treasure" that serves as the undeniable evidence to convince the skeptical prince. Upon seeing the heirloom, the prince realizes the grim truth: "My poor father... All this time, people thought that evil Taoist was him."
Sun Wukong, ever the tactician, realizes that mere testimony is insufficient to overthrow the imposter. He identifies the need for tangible "proof that he killed the real king." To achieve this, Wukong employs a clever ruse against his companion, Bajie. By falsely promising that "treasure" lies within a palace well, Wukong manipulates the gluttonous pig into investigating the depths. This act of "rotten monkey" behavior—as Bajie calls it—leads the pig to discover the "well dragon king," who has been guarding the preserved body of the true king. This discovery provides the party with the physical evidence necessary to challenge the fake ruler.
The narrative takes a humorous yet tense turn as Bajie, seeking revenge for being tricked, attempts to trap Wukong. Upon returning with the king's body, Bajie falsely claims that Wukong possesses the power to "bring him back to life." This creates a difficult predicament for the Monkey King. While the Tang Monk expresses hope that the king can be resurrected, Wukong insists, "I don't know how to do that." Bajie’s persistent sabotage—urging the Tang Monk to "use the tight headband spell"—highlights the dynamic of distrust and rivalry that often permeates the group's interactions. The story concludes on a cliffhanger, with the protagonists possessing the body of the true king but facing internal friction that threatens to derail their mission to restore justice to the Black Rooster Kingdom.
