Three hundred years of peace, once the wall was broken.
Sun Wukong, the victorious Buddha, yawned on the lotus platform for three hundred years, thinking that he would only listen to sutras for the rest of his life. Until his junior brother Sha Seng disappeared silently in the Liusha River and turned into a "specimen" imprisoned in a bead. The remains of the Dragon King of the West Sea were discovered at the bottom of the river. The river flowed backwards and the three stars gathered together.
A man in black robes who calls himself "Wu" comes from outside the Three Realms and hunts gods and Buddhas in the name of "Eternal Specimens". He dug up dragon tombs, dyed spiritual roots, destroyed caves, planted trees full of black fruits in Huaguo Mountain, and built countercurrent formations in Liusha River. He wants to make the five Buddhist scriptures—along with the struggle, faith, and friendship they represent—into a static collection.
If the Buddha is not happy, why should he become a Buddha?
Wukong tore off his cassock and picked up the golden hoop that had been lying dormant for three hundred years. He wants to drag the aggrieved Bull Demon King, find his old friends scattered in the three realms, and step out of the "three realms" that even Tathagata dare not talk about lightly. Ahead is the existence "outside the wall" that even the ancient war can only seal, the hand of annihilation that can reduce all things to "nothing".
But he is Sun Wukong.
The madness of the Monkey King and the anger of the Buddha are always just to break "this is how it should be".
