She could also tell

After the second elder Bai left, Zheng Qiu poked Gu Xin, " "Xinxin, there's something wrong with this person."

Gu Xin looked at Zheng Qiu in shock. you can actually see the problems of the living? I thought you only understood the dead.

Zheng Qiu,"hehe."

Gu Xin laughed,'alright, I'll stop joking. This third master Bai should be here rather quickly. Let's talk after we're done with our questions."

Zheng Qiu understood immediately. Gu Xin must have noticed the problem too.

She knew it. Xinxin wasn't so careless the last two times. How could she only ask these few questions? it seemed that she had already seen the problem and asked this on purpose.

As expected, the third master Bai arrived very quickly.

Back at the mourning hall, the Bai family members were being watched by the soldiers as they returned to their rooms. Gu Xin thought that the second and third master Bai had changed their identities, so they had not changed back yet.
