Things that solve crimes

Yang Zhenghui didn't know when he came behind Qin Henian. Looking at Qin Henian's series of actions, he felt dizzy.

Yang Zhenghui was dizzy here, while Qin Henian successfully marked 3 feature points and marked 2 feature points from the other corner.

"That's all, let's run for a while."

"Ah, let's start running now." Before Yang Zhenghui could recover, the software had already started running.

Qin Henian nodded, "That's almost it." After saying this, Yang Zhenghui came over and said, "Yang Suo, why are you here."

Yang Zhenghui smiled and said, "There is nothing to do, so come and take a look."

After a few minutes, 20 fingerprints appeared in the candidate list. After Qin Henian observed them one by one, he eliminated them one by one, and finally marked them again.

The software started running again, and 20 fingerprints appeared in the candidate list. They were observed, eliminated, and re-marked.

Qin Henian took the trouble to repeat this process.

Doing fingerprint inspection, especially comparing fingerprints, is a tedious process, and the person doing it must be patient.

If you don't have any patience, you won't be able to do a trace inspection.

Comparing fingerprints is like searching for an egg's siblings.

First compare among a bunch of eggs. If you don't match, you have to find similar eggs all over the world, and then compare them again until you match.

As the old saying goes: One after another, there are so many of them.

After comparing for a whole morning, Qin Henian reluctantly announced that the first fingerprint comparison failed.

Yang Zhenghui stood in front of the computer in a daze, wondering where he was? The feeling of what he was doing.

There was also the sleepiness and sluggishness that he had in physics and math classes before.

"Qin Station, we're looking for someone." A young police officer knocked on the door, and the door opened. In addition to the young police officer, there was also... Bai Yanci.

The little police officer took the person and left, and Yang Zhenghui also left with a wink.

After closing the door, Bai Yanci put down the two thermos buckets in his hands and touched Qin Henian's head, "Today we have boiled pork slices, fish-flavored shredded pork, three shredded cold salads, and mushroom chicken soup."

He didn't ask about work, he just took out the meals one by one. If anything didn't go well, just have one meal. If not, just two meals.

Smelling the aroma of the food, Qin Henian quickly put aside his helpless mood and was filled with the delicious food in front of him.

"Who made this?" Qin Huinian was a little curious. Qi Yu could cook, but only those two dishes. Lu Dongyu, it's impossible, so the person in front of you did it?

Bai Yanci handed him the chopsticks and said with a smile, "I did it." Then he said reluctantly, "Qi Yu and Lu Dongyu also helped."

"You are so awesome." Qin Henian praised, smiling so hard that his eyebrows curved, making Bai Yanci soften and soften.

"Eat quickly." Bai Yanci's voice was soft, as soft as the spring rain in March.

Qin Henian first stretched out his chopsticks to the cold salad. The red oil was bright, and the red, white and green colors looked good together. He fell in love with it at first sight.

Seeing that he had eaten the cold salad first, Bai Yanci raised the corners of his mouth slightly.

Qin Henian took a bite of the cold salad, which was soft, crispy, smooth, and not greasy. Then he asked, "Have Yan Ci eaten? If not, let's eat together."

"Okay" Bai Yanci said with a smile. He came here without eating. Wasn't it just to have lunch with his family?

……

After eating, Bai Yanci packed up his things and went home.

As soon as he opened the door, Qi Yu rushed over, "How is it? How is it? Do you like to eat it?"

Bai Yanci said while changing his shoes, "I've finished eating."

Lu Dongyu said quietly, "You and Xiu Xiu ate it together."

Bai Yanci smiled and said nothing, Qi Yu said slightly jealously, "Tomorrow, I will also go to deliver food to Xiu Xiu."

……

in the afternoon

Yang Zhenghui came again, and Qin Henian launched an attack on the second fingerprint.

To no avail

Two hours later, Qin Henian gave up on the second fingerprint and started comparing the third fingerprint.

The third fingerprint is better than the first two fingerprints. Although it is still incomplete, the details are richer.

So he paid more attention to the details.

Enlarge the fingerprint image until the entire screen is the fingerprint part, move the mouse, and lightly outline it.

Yang Zhenghui looked at the pictures on the computer and rubbed his forehead. In his eyes, the pictures on it were ghost drawings.

No longer embarrassing himself, Yang Zhenghui found a seat and sat down, took out his mobile phone, and began to look through previous cases to see if there was any case that could "boost their performance."
