Hu Yong'er encountered a saintess by chance, and was taught magic skills from the heavenly sealed book. She uses the skills to help the poor, but was arrested by the government. Hu Yong'er has nowhere to escape, and could only run back to the saintess, who turned out to be the leader of the Tushan Sect and her birth mother. Hu Yong'er also discovers that the one who is pursuing her is her own elder brother, Zuo Mo, who betrayed Tushan Sect for his own selfish gains. Zuo Mo wants to capture Hu Yong'er to learn about the secret magic of the sealed book and revive the fox tribe. Jin Chengyu assisted Yong'er to find the scattered books of the heavens, learned the magical arts from the book and defeat the evil forces to save the world. Adapted from 《三遂平妖传》written by 罗贯中 & 冯梦龙.
