I sat on Gu Bei's desk, and she sat next to me, wearing a pair of plastic gloves, and carefully took out the big red agate ring from the evidence bag.

"How long has it been since the blood splattered on it?" Gu Bei checked the ring against the ultraviolet light and said lightly.

I nodded, picked up an open sausage on her table and ate it, "About half a year ago." ”

Gu Bei glanced at me expressionlessly, took a test tube containing one-third of yellow powder from the table, and proportioned a bottle of hydrogen peroxide with another bottle of aqueous solution, slowly forming an activator.

"It turned out to be a luminol reaction, but are you really good at doing this, making such reagents, and you don't even wear a mask?" I sat in my position, and said at the same level as Gu Bei's chest with his chest against his back.

She glanced at me, lightly dipped the agate on the ring with a little luminol reagent, and laid it flat on top of a tissue to keep it from lying down.

"I've made this reagent hundreds of times in school, and this time it's already very diluted, wait ten minutes, and you'll know the answer in ten minutes." Gu Bei untied his gloves and put them on the table with a click, then turned around and walked in front of me, and the pair of hands slowly reached into my hands and snatched the sausage from my hand.

"Why don't you just eat a sausage of yours? What's the big deal? I'll just go out and buy one for you. I said angrily.

She glanced at me and said softly, "This is what I fed the stray dogs outside, and you came over halfway through feeding......"

With that, she nodded meaningfully to me, and then Muna turned back to her seat.

I shrugged my shoulders, not looking particularly disgusted, after all, I could finish a bowl of family photos in the stinking men's bathroom, which was a side dish.

Ten minutes passed quickly, and the luminol reaction began to appear on the ring gradually, because the reagent that Gu Bei debugged was diluted, so the reaction on it was not particularly strong, and only a blue-white fluorescence could be faintly seen.

As time went by, this blue-white fluorescence became more and more intense, I glanced at Gu Bei, and then grabbed a disposable mask from the side and grabbed the ring, the area that emitted blue-white fluorescence is very wide, most of them are in the agate part, of course, there are more or less on the finger ring of this ring, but not much.

The luminol reaction in forensic science, in layman's terms, is that as long as there is blood splashed and stained on any object at the scene of the murder, no matter how it is removed afterwards, as long as it is sprayed on it with luminol reagent and observed in a dark environment, the original bloodstained place will have a blue-white fluorescence due to fluorescence reaction, and this reagent does not affect DNA extraction.

"Hehe, Gu Bei, otherwise, you can help me make a DNA Bei by the way, and I'll let you send it to you secretly in a while......" I pushed Gu Bei, who was reading the report, pulled an arc from the corner of my mouth, and pulled her cuffs obscenely and smiled.

She indifferently retracted her cuffs and said, "Why don't you go to the group of people in the forensic examination center to do it?" They have better equipment. ”

Hearing her words, I immediately said righteously: "Can the group of animals in the forensic identification center compare with you?" Your skills are ranked second in Jiashi, who dares to try first, I broke his legs, hehe, isn't this the DNA report not so fast, if you do it, the time will be shortened a little bit, after all, you also know that the procedures over there are really not ordinary annoying. ”

Don't talk about you, even I realize that my brazenness has reached a realm, anyway, I am not familiar with the people in the forensic identification center, and occasionally talking bad about them can make Gu Bei's mood feel comfortable, and my life will be a little better.

"Okay, okay, you can really say anything, I really don't know if Pei Jingyao likes your shamelessness, or if she falls in love with any part of your body, I'll do it for you, but give me a little time." Gu Bei was a little impatient with what I said, so he immediately shook his hand, picked up the ring on my hand and went up to the second floor.

"Bang" A sound of the door closing came from the second floor, and I looked up to see that Guo Yongjia was hurriedly walking out of the lounge, and the mobile phone in his hand, looking at the color, should be Pei Jingyao's.

"Why are you here? Aren't you supposed to be in the Criminal Investigation Brigade? Guo Yongjia asked as he went downstairs.

He walked downstairs quickly, and there were beads of sweat just on his forehead, and he looked a little anxious.

I nodded and told him that there was a new development in the case, and I came back to Gu Bei to make a DNA match.

"I also have new progress here, that girl just woke up suddenly......" Guo Yongjia said excitedly with a smile on his face for the first time.

Seeing that he was so excited, a fool could guess what Ni Hanyao must have said after waking up, I looked at the watch on my wrist, and then sat on the sofa next to me unhurriedly, listening to Guo Yongjia narrate the facts that the woman said.

He said that after the woman woke up, she was still the same as before, doing all kinds of weird postures, and Pei Jingyao proposed to let the woman return to the scene of the crime, which might be rewarding.

Guo Yongjia thought about it right, and immediately called Zhong Li to ask if it was okay to do this, and finally, Pei Jingyao, Ni Hanyao, and Guo Yongjia returned to the scene of the crime accompanied by two criminal policemen.

Since leaving this department, Pei Jingyao's mobile phone has been playing a kind of light music, according to Pei Jingyao, in a state of extreme nervousness, listening to music can relieve tension, and I also know that Pei Jingyao took them back to the scene of the crime and wanted this woman to do something.

After Ni Hanyao walked into the door, Pei Jingyao asked everyone around her not to speak, and not to make as many faces and footsteps as possible, which made the two criminal policemen and Guo Yongjia behind her a little confused, but who made the family a psychological expert, and they could only do what she said.

"I don't know what magic Pei Jingyao used, as soon as this woman entered the door, she walked to the door of the other bedroom, stood stunned for five minutes, and then reached out to open the door, and when we entered, this woman disappeared out of thin air, do you want to know where she is?" Guo Yongjia chattered and spat in front of me, probably because he was too excited, and there were a few times when I couldn't help but want to hit him.

"What? Under the bed? I asked, raising an eyebrow.

He was slightly stunned and said in surprise: "How do you know?" When we went over to look for it, the woman was literally lying under the bed. ”

I rolled my eyes at the tiger and continued to listen to him say what he had tasted.

Guo Yongjia lifted her cuffs and wanted to pull her out from under the bed, but was stopped by Pei Jingyao, and after about ten minutes, she actually crawled out from under the bed by herself, and then walked to the living room against the wall.

According to Guo Yongjia's narration, Ni Hanyao opened her eyes when she walked in that room, and she didn't blink her eyes during the whole process, which looked really weird.

And when she reached the door of the master bedroom, she did not enter as she used to walk, but grabbed the wall next to the master bedroom with one hand, and then slowly stretched out of the master bedroom door with half of her face exposed.

Immediately afterwards, a dramatic scene happened, the woman's whole body began to shake violently, and then, she was helpless on the back of her head, and her whole face was extremely hideous, Guo Yongjia wanted to step forward to help this woman, but was stopped by Pei Jingyao.

They waited in place for a few minutes, and then, like Sichuan's face, the woman's face changed instantly, and her hideous face instantly became calm, she slowly got up, and then raised her legs to walk out of the door.

At this time, Pei Jingyao's mobile phone suddenly sounded a sound of gongs and drums, very noisy, very noisy, and even asked Guo Yongjia and the old men to cover their ears and ask her to turn on the sound a little lower, Pei Jingyao didn't pay attention to it, on the contrary, she turned up the volume of the mobile phone even louder.

Slowly, Ni Hanyao seemed to be stimulated by something, covered her ears with both hands, and revealed a hideous face, and then, her whole person instantly lay on the ground weakly.
