Jiang Ning slid the polygraph to the side, and Qi Xingzhou tacitly took it.
Miao Bin's cell phone was still in Jiang Ning's hands when she turned her head to look at Zhang Lang, "Officer Zhang, come and take a look."
Zhang Lang had been standing on the side for a long time and now, seeing that he finally had a role to play, hurried over.
"We've all used WeChat and should know that, even if you're kicked out of a group chat, as long as you don't delete the chat window, you can still see the chat history that took place in the group," Jiang Ning said.
Hearing Jiang Ning's words, Miao Bin, who had been hiding behind his parents, seemed to remember something, and he suddenly looked up at Jiang Ning.
Jiang Ning didn't pay attention to Miao Bin's reaction; she was already showing Zhang Lang the chat history she had just discovered on Miao Bin's phone.
Before coming here, Jiang Ning had already checked Miao Bin's information from the System.
