Hearing that Qiao Xi said there was a way, CHEN Si looked at Qiao Xi in some panic.

"What method?" asked the counselor.

"Check your fingerprints."

Hearing Qiao Xi's method, CHEN Si was relieved at first, and then CHEN Si spoke to Qiao Xi with some contempt, "check your fingerprints? Who do you think you are? You can check your fingerprints if you want to? Don't tell me you're ready to call the police."

Deng Xiangyue laughed and felt as if he had heard a big joke.

The Counselor's expression was also a little embarrassed. "Qiao Xi, there's no need to alarm the police about this kind of thing? Moreover, the police won't accept it."

The Counselor's embarrassment and CHEN Si's ridicule did not pay attention to Qiao Xi. "I have a relative who works in the police department. This morning, I have handed over the mop and mop bucket in the library bathroom to my relative. I think he should have passed the results to me now."

Qiao Xi pointed to the computer, "teacher, can I log in to my email?"

Counselors always feel that there is something wrong with this matter, but they can't say it again. They can only nod their heads.

Qiao Xi logged into her mailbox on the Counselor's computer. Sure enough, she saw an email in her inbox. She opened it and there was a fingerprint inspection report.

CHEN Si didn't expect Qiao Xi to have such a skill, but they didn't pay much attention to it.

"You don't even have our fingerprints. How can you prove that we did it? Can any of the fingerprints on it be said to be ours?" Deng Xiangyue put her hands around her chest and hung her mouth while chewing gum.

Qiao Xi ignored them, but clicked the photos in the mailbox. "Teacher, the three pens in this picture are Deng Xiangyue, CHEN Si and LV Fangfei, and their names are engraved on the cap.

Each pen collected a set of fingerprints, belonging to the three of them. On this mop, the same fingerprints were found in both places. This is the inspection report. The fingerprints are Deng Xiangyue's.

There are also fingerprints at the bottom of the mop bucket and the position of the handle. There are two groups, which are the fingerprints of LV Fangfei and CHEN Si. Of course, there is another group of the same fingerprints on the mop and mop bucket, which are the fingerprints of aunt cleaning.

Therefore, what they just said about not touching the mop and mop bucket is totally lying, which is enough to show that they shut Xiaoxiao in the toilet and took Xiaoxiao's schoolbag. "

Tao Yun, who had already lost their chin, stared at Qiao Xi dumbfounded.

They swore that when they came, they really didn't know that Xi Xi was so well prepared! This pile of evidence, not to mention counselors, they were shocked!

After hearing Qiao Xi's words, CHEN Si suddenly approached the computer screen. When he saw those pens, CHEN Si looked frightened, "how can you have our pens!"

"I found it in Xiaoxiao's schoolbag." Qiao Xi said lightly.

"You just stole it! It must have been stolen when you went to our dormitory yesterday! How can we put the pen in Huang Xiaoxiao's schoolbag!" Lv Fangfei said loudly, pointing to Qiao Xi.

Qiaoxi shrugged. "This is about to ask yourself, how do I know, and, you say I steal, is there any evidence?"

In fact, these three pens were taken by Yu Xue's dormitory when everyone was asleep in the middle of the night last night.

As a killer in her previous life, it was not difficult for her to escape the school camera and sneak into the student dormitory.
