Adalos was once the first wise man under the command of the god king Korra in the divine world. He was named the envoy in charge of the most powerful holy book and the descendant of the holy goddess Venus.
After the teacher, the Queen God King fell in a battle with the demon god Diavolo, the war god Yak rebelled and wanted to unify the god world. The two parties launched a god war. Adalos exhausted the holy books, the gods fell, and the holy books descended to earth. Adalos possessed Wu Cheng, the younger brother of Wu Yan (the one possessed by Diavolo), the leader of the black forces in Yincheng. After awakening, he started a battle for the Holy Book with Yak and his men. In the process, he reunited the major gods and the saint Venus, and also met his lover Chen Yao. Finally, Wu Cheng led the gods to launch a divine war with Yak, and finally successfully annihilated and restored the Kingdom of God.
