Su Xuange was born with the ability to communicate with monsters and was expelled as a monster by his tribe. After escaping into the monster forest, she rescued the seriously injured Nine-tailed Fox Lord Bai Ze. Su Xuange summoned monsters in the language of beasts to heal Bai Ze, and Bai Ze taught her to control the power of beast languages. The two went on an adventure together to tame ferocious monsters and form an army of beast spirits to fight against evil cultivators who wanted to capture the monsters to refine medicine. In the end, Su Xuange became the master of the beast spirit world and spent the rest of his life with Bai Ze deep in the forest.
