It wasn't Zou Ba and Zou Shisi's first time in Pingan Town. Furthermore, Xue Sifu had long known that Xue Yan was the Crown Prince. It had been so long since the first time he heard about it. Xue Sifu might not know the other secret guards, but he knew Zou Ba and Zou Shisi.
Moreover, once Xue Yan saw the note he wrote, he knew that Xue Yan would send a few people over.
He guessed that the people sent by Xue Yan should be here soon, so he opened the window to let them in.
"She's in the room opposite me," Xue Sifu said without wasting time. He still had a smile on his face as he lowered his voice so that only Zou Ba and Zou Shisi could hear him. "When you investigate, be careful. She looks skilled."
Before Xue Sifu could finish, he saw Zou Shisi and Zou Ba looking like they wanted to talk. He stopped himself and asked, "Is there something wrong?"
"Yes." Zou Bayi nodded and lowered his voice.
