Xiao Ya told Xie Jing what had happened back then. After all, Yunbao had only seen the memories left behind and not the entire truth.
She didn't know what was wrong with herself at first. She thought it was because she was tired that she felt uncomfortable every day. It wasn't until she couldn't get out of bed and move that I realized what had happened.
Xiao Ya's family had records of Innate Spirit Bodies. A few hundred years ago, there was someone with such a physique. However, after that person died, the family became ordinary people. There was no longer a situation of Innate Spirit Bodies. Everyone thought that this physique would not appear again.
Therefore, when she realized that she was born with a spirit body, the first thing she did was to confirm if Xie Jing had inherited this physique. When she performed the ritual with blood, the light emitted had already told her the answer.
