Journey to the West is a carefully packaged "god-making movement". The real battle to defeat the Buddha is not Sun Wukong, but the six-eared macaque. The real Wukong has been secretly refined by Tathagata in the real and fake Monkey King. His body and fighting strength were stripped away, leaving only a trace of his soul to be tortured.
The pattern of the three realms: Buddhism and Taoism maintain order on the surface, but in fact harvest the fate of all living beings through the "merit system". Heavenly Court and Lingshan have already reached a community of interests and regard all living beings as pawns and nourishment.
