In which literary works did the role of the Monkey King first appear?

In Shihua, there is an important figure "Walker"-as far as Shihua is concerned, his role should not be exaggerated. In the Buddhist story of Shihua, the main function of the walker is only to act as an intermediary between the Tang Priest and the "Great Brahma King" (the representative of mana), so that the Tang Priest can rely on the power of the Buddha through him. The added ingredients are very heavy. If we delete all the deeds of the walkers in Poetry Talk and replace them with the Brahma King or other figures, the story will still hold water. In addition, this character is not only attached, but also incomplete. Starting from "The Eleventh Girl Country", the walker's play has basically ended, and the next role is only to "lead the way". The most basic element of success in learning Buddhism is the "incredible" virtue of Tang Priest. The significance of this character lies not in how many plots have been added to the story of Buddhist scriptures in Shihua, but in the fact that "appearance" itself has greatly increased the means to solve the conflict between Buddhist scriptures and difficulties. From then on, as long as there is no limit to the power of the walker, there is no limit to the development of Buddhist stories, as long as there is a suitable way to contact Tang Yan, regardless of whether it is reasonable for Tang Yan. In fact, this is a way to learn stories and get rid of the shackles of historical truth. It is somewhat accidental for Monkey to be the assistant of Tang Priest, but the appearance of this role is inevitable. In order to make the story of Buddhist scriptures develop under the framework of skill setting, there must be a character to replace Tang Priest as the protagonist of the story. Later Buddhist stories all noticed the significance of the appearance of the walker, so the scenes of the walker in the Buddhist stories of the Song and Yuan Dynasties increased rapidly, which was the second adjustment of the relationship between the parts of the work. The core of this adjustment is to design an internal structure that is compatible with Tang Priest and the Monkey King without changing the conflict of drama. We believe that it is understandable that the story of the traveler and the story of the scriptures have not yet formed a complete internal structure of the drama. However, under the background of the rapid development of scripts and zaju in Song and Yuan Dynasties, it is impossible to design an internal structure compatible with Tang Priest and the Monkey King without changing the major drama conflicts.
