Five hundred years later, the four masters and disciples of Tang Monk passed by Yudai Forest. Because Wukong had forgotten the past, they beat her to death. After going to the West to learn scriptures, Tang Monk and Dragon Girl accidentally got into the black hole where time was reversed. When time was reversed, the tomorrow they lived was the day after tomorrow for normal people. Due to time and space going back, Tang Seng saw the former corpse demon waiting for Wukong to come back in Huaguo Mountain. In order to save her from the pain, Tang Seng told her that the monkey had gone to the West.
Longnu once saved a baby boy named Jiang Liu'er in the past. She couldn't bear to watch Jiang Liu'er reincarnate in ten lives, so she forced him to eat the flesh of the old monk Tang Seng, hoping that he could live forever. However, Jiang Liu'er, who didn't want to eat Tang Seng's flesh, changed from an enlightened monk to a crazy ruffian monk. Later, he happened to meet himself who got into the black hole of reversing time after studying in the West. So after studying in the West, Tang Monk made a mistake after eating his own flesh. The crazy Tang Monk went to the West to obtain Buddhist scriptures.
