MTL - Super Manufacturing Force-Chapter 452 Impossible clue

"What is this?" Zhong Zheng asked in surprise.

Zhao Xu pursed his lips: "If I didn't guess wrong, this should be a fragment of the battery used in the bomb detonation device!"

Whether it is a time bomb or a remote-controlled bomb, the start-up device requires a battery to support operation, and when the battery is installed, it is easy to leave fingerprints.

However, once the bomb explodes, all parts will be destroyed, and fingerprints are of course no exception, so even professional killers generally do not care about this.

Sure enough, Zhong Zheng frowned slightly: "You want to look for fingerprints on this fragment? I'm afraid it's difficult, the whole battery has been blown up into such fragments, and that kind of high temperature is hard to keep fingerprints!"

Zhao Xu smiled slightly: "That's not necessarily. According to the law of the" Lockard's Material Exchange Principle ", any object in contact with each other will exchange material information with each other. This is a rule that does not take human will as the transfer!

Edmond Lockard, a famous French investigator at the beginning of the twentieth century, authored a book called "Locard's Principle of Matter Exchange".

According to the description of this principle, when criminals commit crimes, they must exchange material information with the objects they contact, leaving behind clues, such as fingerprints, footprints, and traces caused by crime tools. Or bruises or scratches during a fight.

In addition to these, criminals may also have hair, dandruff, sweat, body surface oil and other secretions, or clothing fibers, dust sticking, or even the exchange of odors emitted by humans or objects, such as perfume or furniture. Special smell.

All of these are clues to track down the criminal. The fingerprint on the battery chip appears to have been destroyed, but in fact there are still traces left on it. It is just a general scientific and technological method that cannot be used. These traces serve as clues to the investigation.

What is a fingerprint?

In fact, the fingerprint is a raised stripe on the surface of the finger, and the fingerprint itself will not be printed on the object.

The human body secretes sweat, oil, and so on. These things are wrapped in fingerprints, and they stay on the surface when they touch the object.

This is like a seal. A dry seal can't print anything when it is killed. Only after it is stained with ink, can the pattern on the seal be printed on the paper.

So a fingerprint is equivalent to a seal, and sweat, grease, etc. are equivalent to printing ink.

Sweat, grease, etc. are actually substances and are composed of individual molecules. Although the fingerprint was destroyed, Zhao Xu believes that there must be sweat and grease molecules on the battery fragments.

These things may not be useful to others, but Zhao Xu can use the manufacturing power to extract these molecular residues, and then use the positions of these molecular residues as spatial nodes to let the Holy Spirit calculate the most likely fingerprint pattern combination. Come.

Zhao Xu took a deep breath and created the original energy to shroud the battery fragments. The consciousness followed closely, and quickly opened the microscopic state. Suddenly, the entire battery fragments were continuously enlarged, and a scene of molecular accumulation soon appeared.

He carefully extracted the molecules that belong to sweat and grease, and remembered the spatial arrangement of these molecules. Finally, in the elementary crystal, he formed a messy pattern model composed of countless molecules.

"Holy spirit, it's your turn!" Zhao Xu said in his heart.

"Okay, wait a minute!" The Holy Spirit replied, and immediately began to deduce the messy pattern model, and saw a striped line that began to continuously connect between the various molecules.

After a while, one fingerprint model appeared in the original crystal, these are the most likely fingerprint pattern combination calculated by the Holy Spirit.

In the monitoring room, Zhao Xu closed her eyes silently, while Zhong Zheng waited anxiously.

About ten minutes later, suddenly, Xu Xu opened his eyes.

"How's it? Are there any clues?" Zhong Zheng asked immediately.

"Yes, you wait!" Zhao Xu nodded, immediately lowered the table, then spread his hands.

As manufacturing energy surged, a piece of white paper appeared in his hands, and then seven clear fingerprints appeared on the white paper.

Zhao Xu handed the blank paper to Zhong Zhengdao: "Lao Zhong, let someone check these seven fingerprints, and one of them must belong to the killer!"

"Really?" Zhong Zheng asked suspiciously. There was no way. Zhao Xu's work was too incredible. It was hard not to make people doubt.

However, despite suspicion, Zhong Zheng took out his mobile phone, scanned all seven fingerprints, and then used software to find the internal criminal fingerprint records.

As he waited, Zhong Zheng asked with a strange look: "Is this okay? I said Zhao Xu, aren't you fool me? You just made seven fingerprints, which is too ridiculous?"

"Hey, Lao Zhong, you'll know when you wait and see!" Zhao Xu grinned, showing a white tooth.

"So get mysterious!" Zhong Zheng muttered.

"Dididi ..."

Suddenly, the phone rang a message to remind, Zhong Zheng immediately looked down, surprised: "It really does? Your kid is really amazing, let me see who the fingerprint belongs to? Well, it is this guy ... "

"Who is it?" Zhao Xu frowned slightly.

Zhong Zheng handed the phone over: "This guy is code-named Viper. No one knows the real name. He is one of the top killers in the world today. He is known for his cruel means and secretive actions. Hidden, one-hit kills are the main reason, so this code was given. His mission success rate has reached more than 95%. He is a pretty terrible killer! "

Zhao Xu took the mobile phone and looked at the photo above, and found that the poisonous snake was a white man who was less than forty years old and had a normal appearance and a very friendly manner.

At first glance, this man looks exactly like the kindness of an uncle next door, and it is difficult to associate him with the world's top killer.

It's also scary to think about it. Who will be really prepared for such a person when he approaches the target?

"How are you going to check?" Zhao Xu asked.

"Now that he has a clear goal, he can blow up the monitoring room of the police station, but he cannot eliminate the surveillance video everywhere!"

Zhong Zheng sneered, and immediately called a subordinate next to him: "Xiao Liu, immediately call the traffic command and control center and ask them to call up the surveillance video of all the streets near Qiaoxi Branch today. We will hurry up! "

Zhao Xu nodded and agreed that the streets were full of cameras this year. The poisonous snake can destroy the police station's monitoring room, but it is impossible to destroy all the surveillance cameras around the police station. 2k novel reading network
