Du Jing said: "The bucket and the dustpan don't prove anything, but the fingerprint has two characteristics, one is the same lifelong characteristic, compared to everyone knows, the other is unique, that is, the same fingerprint can not find a second similar in the whole world!"

"How is it possible! I feel that the bucket is round, how can it be different?"

Those present expressed their doubts, and even raised their fingers to compare with the others.

In this comparison, I really found some similarities.

"That's really the case! The bucket in my hand is different from the bucket in his hand!"

"Oh my God! This is amazing. ”

Du Jing smiled and ignored the monks who were busy comparing themselves with the rest of the people who were busy with novelty.

Instead, the fingerprint comparison began.

Fingerprint comparison is divided into automatic comparison of system library and manual comparison.

The system library is its own algorithm and law, according to the details of the normal law, such as the location of the feature point, the flow of the grain line to the pattern structure for comparison, but the alien fingerprints of some crime scenes cannot be distinguished.

However, even if there is a way to tell, Du Jing does not have a fingerprint library to use, and the fingerprint module of the current system has not yet been opened.

The other is manual comparison, manual comparison is the most test of the patience of the trace police, generally only in the encounter with fingerprints on the surface or other fingerprints of the opposite sex will be used for manual comparison, this thing is to see the experience and patience.

The main focus is on the position, pattern, location of feature points, and the type of detail features.

The first thing to determine is that the pattern should match!

The so-called pattern is bigger, it is a bucket or a dustpan, and Du Jing was stunned and directly ruled out the person who had the middle finger of his right hand on the glazed tile.

To put it mildly, the bucket in the pattern is also divided into different bucket types such as the fingerprint center spiral bucket and the fingerprint center small stick bucket.

Obviously, this fingerprint is very round, obviously the center spiral type, after leaving this pattern of glazed tiles, it is necessary to analyze the direction of the fingerprint lines.

The fingerprint lines on the suspected tiles are clockwise spirals, and then the clockwise spirals are left, and the rest are excluded.

At this time, there are not many tiles left, but there are still about seven or eight.

The next step is to compare the feature points, select the triangular area centered on the feature points, and compare them one by one.

Time passed slowly, maybe it was a little long, and someone said impatiently: "Du Zhutou, you have been comparing the people in our hall, but this tile was taken off the roof, maybe the suspect has already escaped from the roof." ”

As soon as these words came out, they immediately aroused everyone's approval.

"yes! How could a suspect move the tiles and not leave the roof?"

"Moving the tiles for no reason, isn't this taking off your pants and farting, an extra move?"

Wang Zhishuang snorted coldly and said: "This person prefers to play tricks, I think he and the suspect are in the same group, deliberately delaying time!"

It seems that the robot just now made the simple-minded Zhang Lei learn to recall the details, and he suddenly said: "Yes! After this Du Jing came, not only did he not buy anything, but when I asked him about his face, he took out a kettle to sell, and when he sold it, it caused such a big movement!"

Maybe he just deliberately provoked the incident, wanted to get everyone's attention, and then let his accomplices go in and steal!

Now it's even more here to keep delaying time, and saying that the handprints are different for everyone, this is completely creating a chance for the suspect to escape!"

"That's right, if I find that there is a problem with that tile, I will definitely chase it out as soon as possible, where will I cook kelp soup and what will color the tile!"

For a while, everyone pointed the finger at Du Jing, and even Qian Zhihong couldn't help but suspect Du Jing.

When he found out about the theft, Du Jing had just had a conflict with someone and was about to leave the Ministry of Industry, so he must be ready to get out quickly after he succeeded!

And his request, he was not afraid of trouble at all to refuse, it must be to delay time!

Yes, Du Jing was the first to discover the gap, and he didn't inform himself, and he was blocking himself after he knew.

Although there was no trace found when he went up with him, if Du Jing was really an accomplice, he must have been prepared.

Did you really believe him wrong?

"Du Jing!" Qian Zhihong stared at Du Jing, who was still holding the glazed tiles and kept comparing, and said coldly: "In vain, the old man trusts you so much, and quickly tell who your accomplice is, and the old man can also see that the emperor's face is not like you!"

Du Jing carefully identified the fingerprints on the glazed tiles in front of him, rubbed his eyes, raised his head and said, "Qian Shangshu, others don't have brains, don't you either?"

Qian Zhihong was stuck by Du Jing's words, and he was furious, but he was not the only one who was angry.

Zhang Lei scolded angrily: "You kid really gave you face! Who do you say has no brains?"

"What about you!" Du Jing continued to compare the fingerprints on the glazed tiles, and said to the base without raising his head: "There are no footprints on the roof, and there are no fingerprints even on this tile."

Why don't you let me do it, how do you move only one tile and go out of the roof without leaving any traces? ”

Zhang Lei said without thinking about it: "I'll go out!"

"Edgeworth will produce spiritual power fluctuations, and are you sure that your Sky Magic Weapon can drill through that gap?

Only by shrinking the bones can you climb out of that gap, and obviously crawling is to leave fingerprints. However, there were no fingerprints left on the top of this tile or several nearby tiles.

And the ash under the gap in the back hall is only ash, not the soil on the roof!"

Du Jing looked at Zhang Lei with a smile and continued to ask, "So if you think about it again, what other way can you leave from the roof?"

Zhang Lei racked his brains and finally thought of a way to continue the bar, and said: "In case that thief's magic weapon is very small, and he is proficient in clavicle technique, he can directly remove the tiles and leave without leaving a trace!"

Du Jing smiled, put the tile aside, and said, "Let's not talk about your conditions, and we won't talk about how the suspect didn't move the top of the tile and closed the tile from the inside.

Let's just talk about it, what I just said, the sword will produce spiritual power fluctuations, and the guards outside the door are monks in the Dan cultivation period, how can they not notice it at all?

Why don't you explain this to me?"

All these conditions were set by Zhang Lei, so Du Jing threw the question back to Zhang Lei, hoping that he could say the answer he wanted.

Because for the suspect, Du Jing already had an inference in his heart.
