The White Bone Demon who was beaten to death in the original work was transported by future consciousness at the moment before his death in the third round, and obtained the complete script of Journey to the West and a "relic of reincarnation" from Tathagata. She found that every time she died, she made a note in the Buddhist "karma book". The more merit she accumulated after her death, the higher her reincarnation status would be. So she planned a "serial substitute plan on the way to learn the scriptures": let Sun Wukong kill three false selves to accumulate merit, and then reincarnate as the most powerful Princess Zhenxi in the Tang Dynasty, stirring up troubles between the upper class and heaven, and finally intervened as a legal disciple of Buddhism in the dungeon of Flame Mountain and the real and fake Monkey King.
