沙悟浄
Chapter 100, the final chapter, quickly describes the return journey to the Tang Empire, and the aftermath in which each traveller receives a reward in the form of posts in the bureaucracy of the heavens. Sun Wukong (Monkey) and Tang Sanzang (monk) achieve Buddhahood, Sha Wujing (Sandy) becomes an arhat, the dragon horse is made a nāga, and Zhu Bajie (Pig), whose good deeds have always been tempered by his greed, is promoted to an altar cleanser (i.e. eater of excess offerings at altars).
