As the standard-bearer of the "Seven Sages" to which Niu and Jiao Mo belong, he is an ancient strong man who survived fierce battles with many gods. Although all the seven demon kings under the Seven Days Great Sage hold the title of Great Sage, only the Monkey King loves to be called "Great Sage", and her demon fairy and the land gods agree that she is an outstanding person who can be called Great Sage. There are not a few people who believe that "Monkey King" is the king of God. Even other gods have people who believe so.
However, after forming a grand alliance with the six demon kings, the Great Sage of Qitian started a great war with the Heavenly Emperor and the Taoist God, and was finally defeated by the protector of the Twelve Days and Sakyamuni. After being imprisoned for 500 years, he took Genjyo Sanzo as his teacher and went to Tianzhu.
