Chương 861: Yu Shi

After Crystal walked out of the bathroom, a voice suddenly rang out. "Where were you yesterday?"

Crystal was startled and immediately made a fighting stance. At that time, she instantly forgot that she was only wearing a towel.

However, when she saw the person who had just spoken, Crystal let out a sigh of relief.

'Sigh. She always appears out of nowhere.'

Crystal's expression instantly turned normal.

In front of her, an old woman about sixty years old was sitting on the couch. She was sipping her tea and behaving as if it was her apartment.

That old woman was Yu Shi, Crystal's martial arts teacher.

After Crystal sat next to her, she inquired, "Master, when did you arrive? And what are you doing in my apartment? Can you stop appearing out of nowhere like this? You can give me a heart attack, you know?"
