The essence of the Chaotic Demon Ape was so powerful that after Sun Wukong assimilated it, his temperament had difficulty controlling this power, and instead became affected by the remaining will of the Demon God inside, falling into madness.
With the energy accumulating within him, Sun Wukong felt unbearable. Hence, he needed to vent it through battle, to let this power out so as to return to normal, and to awaken from his madness.
If not, the power would accumulate even more, and if it was unable to be vented for a long time, the residual thoughts of the Chaos Demigod would become stronger, completely distorting Sun Wukong's will, turning him into a Fierce Beast from which there would be no return.
Although Sun Wukong had lost his sanity, he still wanted to live without turning into a Fierce Beast. Therefore, driven by innate instinct, he began to vent.
"Roar!"
