Xu Yanxin was the lowest servant disciple in the sect. She was dressed in a gray-black disciple uniform and had an eye-catching mustache. Those who didn't know better thought she was a male disciple. After returning from the demon-slaying battlefield, she found some strange changes in herself.

She herself has also undergone some changes, and her ears and eyesight have become much brighter. Until one day, she discovered that she could actually understand the voices of the spiritual beasts... Her status in the sect began to rise. Finally, she met the legendary sect master. Senior Brother is very humble and polite when dealing with others. But I have a problem with her. She even found her senior brother jumping out of her window in the middle of the night... This... This is not good...
