Su Yibai is the owner of Longtang Inn, and the Su family is a family of exorcists. Su Yibai took over this inn after graduating from university. When she was young, her grandfather told her that there was a thousand-year-old ghost locked under the inn. The Su family must guard this inn for generations to prevent the evil spirits from escaping. Su Yibai's mother divorced her father when she was five years old. Her father was afraid of this and had been doing business abroad for many years. Apart from giving Su Yibai some living expenses every month, he didn't care about her. Over time, the mission of exorcizing the family fell on her shoulders.
Purpose: Protecting justice and kindness is Su Yibai's mission as an exorcist
