How did you explore the bottomless pit in the Monkey King? What kind of image does it show in the Monkey King?

This is the eighty-two and eighty-three episodes of Journey to the West. In order to find out, the Monkey King jumped into the hole and turned into a fly. He tried to get into the monster's stomach while drinking water, but failed. On the second expedition, Wukong turned into a fly and a heart, and entered the monster's stomach, forcing the monster to send Tang Yan out of the hole. As a result, after the hole came out, the monster took Tang Yan away. On the third visit, Wukong went straight in, but the monster hid. Wukong found the tablet of Nezha, the king of Li Tian, and complained to God. Finally, with the help of Li Tianwang Nezha, the monster was caught and the Tang Priest was rescued. From this process, we can see Wukong's perseverance, high morale and great intelligence.
