Sequels
The brief satirical novel Xiyoubu (西游补, "A Supplement to the Journey to the West," c. 1640) follows Sun Wukong as he is trapped in a magical dream world created by the Qing Fish Demon, the embodiment of desire (情, qing). Sun travels back and forth through time, during which he serves as the adjunct King of Hell and judges the soul of the recently dead traitor Qin Hui during the Song Dynasty, takes on the appearance of a beautiful concubine and causes the downfall of the Qin Dynasty, and even faces Pāramitā, one of his five sons born to the rakshasa Princess Iron Fan, on the battlefield during the Tang Dynasty. The events of Xiyoubu take place between the end of chapter 61 and the beginning of chapter 62 of Journey to the West. The author, Dong Yue (董說), wrote the book because he wanted to create an opponent—in this case desire—that Sun could not defeat with his great strength and martial skill.
