Chu Ning was also a little embarrassed, it was really difficult to judge that both sides held their own words, even if he believed what Tan Yunzhi said, he couldn't draw conclusions without any evidence.

But Chu Ning, who has been a forensic doctor for more than ten years, is not a vegetarian, although he has not studied criminal investigation systematically, but he has never eaten pork and has seen pigs run, forensic doctors and colleagues who do criminal investigation are on the scene together every time, and they will discuss the case together, even if they don't study deliberately, they have mastered some ideas for handling cases.

Traces will be left when something happens, this is a wise saying, so Chu Ning thought about it for a while, and then paced to the location of the "crime scene".

The broken porcelain pieces had already been cleaned up, and the ground had been wiped, leaving only some water marks, Song Qianqian was standing next to her, seeing Chu Ning coming over, she let it go slightly, Chu Ning noticed that there were tea stains on the corner of her skirt, and suddenly she had an idea, Chu Ning thought of a key, and a smile appeared on the corner of her mouth.

Chu Ning turned to face Zhou Liu'er and said with a smile: "What were you doing when it happened just now?" Chu Ning secretly despised herself, every time she saw her colleagues interrogating prisoners, she felt bored, it was nothing more than all kinds of psychological warfare, I didn't expect that I would have such a day, but I was too pediatric, and I was probably going to laugh off my big teeth when my colleagues knew it, alas, I guess I wouldn't have a chance to go back.

Zhou Liu'er didn't expect Chu Ning to be the first to ask her, and if she wanted to ask, she would have to ask Song Qianqian first! Seeing Chu Ning's eyes that seemed to be very contemptuous (in fact, she was despising herself), she was inexplicably weak-hearted, but she pretended to be calm, stood up steadily, and said, "If you go back to the house, I was embroidering just now." “

"Do it for me. Chu Ning said softly.

Zhou Liu'er was confused, she didn't know what Chu Ning meant, but she couldn't help but do it, so she sat down and picked up the needle and embroidered it according to her words, but she kept beating the drum in her heart.

Zhou Liu'er embroidered is to wipe the forehead, the big embroidery frame is not used, only an embroidery bandage is used, fixed on the front embroidery frame, because embroidery needs to be drawn behind the embroidery bandage, so each embroidery girl embroiders the body is leaning forward, so that the feet fall to the ground to support, and will not be warped, this era is wearing a skirt, so both feet are blocked by the skirt, Chu Ning noticed that Zhou Liuer's skirt did not have traces of tea splashing.

Seeing this, Chu Ning felt a little more sure in his heart.

"Stick your left foot out. Chu Ning's voice carried a hint of irrefutable.

Zhou Liu'er was shocked, and had a bad premonition, but if she didn't do it, she might not be able to pass this level, so she had to slowly stretch out her left foot.

There are no men here, Chu Ning stepped forward and lifted her skirt up slightly, and her heart was suddenly determined! As long as she has done it, she will definitely leave traces! Sure enough, what she said is right!

There were a lot of splashed tea stains on Zhou Liuer's left shoe, under the legging pants, and even two or three points of tea foam.

Everyone also gathered around to see, only two or three people showed a clear look, and the rest were very dazed, not knowing what this meant!

"What do you say about this!" Chu Ning's voice revealed a coldness, she would still be able to pretend to be cold after staying with Chu Yunzhou for a long time.

"It was splashed with tea just now!" Zhou Liu'er looked innocent, but she was cold in her heart, knowing that she would bite to death no matter what, and she couldn't admit anything else, otherwise she would be deprived of the right to participate this time, and looked around and pointed to Song Qianqian's skirt and said, "She also has it on her skirt!"
