Sun Wukong received news from the Underworld.
After pondering for a moment, he sent Black and White Impermanence back.
The changes in the Underworld were significant, yet seemed irrelevant.
It made Sun Wukong realize something.
"What exactly is Buddha trying to hide?"
Buddha's actions were so overt, it made Sun Wukong increasingly suspect that the origins of the anomalies were complex.
He seemed to sense the unease in Buddha's heart.
How could such a nuanced Buddha reveal his intentions so thoroughly?
He was trying his best to hide something, seemingly even at the cost of inciting conflict to divert Sun Wukong's attention.
But what could it be that he did not want Sun Wukong to know?
After contemplating, Sun Wukong returned to Wanling Country and found the Jade Emperor.
"I am already aware of the situation in the Underworld."
The Jade Emperor knew why Sun Wukong had come.
