Who is the founder of Bodhi in Journey to the West?

According to The Journey to the West's description, the fictional characters in the novel are both Buddhists and Confucians, so they should be more Buddhist. Judging from the source of his novel creation thought, the main image comes from Xu Bodhi, one of the top ten disciples under the Buddha's throne, who is famous for "solving the void first".

According to the setting of Journey to the West, Bodhi should be equal to Buddha. Because the Tathagata Buddha knows everything in the world, but he doesn't know who the Monkey King's master is, there are only two reasons: First, he really doesn't know, so it is obvious that two people are on the same level; Second, I know, but the Buddha pretends not to know, which shows that the Buddha has a very close relationship with the Bodhi ancestor, or it is to promote the Tang Priest to learn from the scriptures, introduce Buddhism to the Tang Dynasty in the East, and reach a private tacit understanding.
