The messy concrete fragments suddenly turned into a digital virtual three-dimensional drawing. This made Zhang Zhitong and the policemen widen their eyes.

When did they ever deal with such advanced equipment?

Ten seconds later, the modeling was complete.

Just as the police were curious about what the next step would be, these messy concrete shards models flew up on the big screen.

"...... in Model Calculus"

“5%… 55%… 100%…”

As the progress bar moves quickly, these broken models magically come together one by one.

It's like a digital wall that has been shattered and restored. When the progress bar reached 100 times, the original messy and broken virtual model had turned into a square virtual concrete wall full of cracks, and the whole process took less than a minute.

The policemen's eyes widened a little wider, because the reassembled virtual wall could clearly see that there was an irregular deep hole the size of a potato chip bucket in the center.

There are many defects around the deep cave that have crumbled into particles and cannot be restored. But this does not prevent people from intuitively judging that this is a deep circular hole.

Concrete cracks spread from around the deep hole in the form of a net. It's like a piece of car glass, the kind of crack that is shattered by a bullet.

"Hiss......"

The policemen gasped, could it be that this wall was shattered by armor-piercing bullets?

How loud was that, and how daring?

"If it is a high-speed object impact, the passage created by the gangsters in the wall should be circular. But the passage left at the scene is obviously square. A policeman from the trace examination room whispered: "And we have not detected traces of gunpowder residue on the concrete fragments." ”

"It's not a high-velocity object impact. Ye Qing carefully looked at the restored three-dimensional simulation diagram and explained: "If I guessed correctly, this should be the principle of static blasting. ”

"It's not blasting with explosives, as everyone understands, it's blasting with mechanical energy. ”

"Rock and concrete, which have extremely high external compressive strength, but low internal and outward tensile strength. If the external compressive strength is 100, then the internal strength is only 2 to 10. ”

"Hydraulic splitter, I don't know if you've seen it?"

"To mine stones, you only need to drill a few small holes, put a splitter into the holes, and in two minutes, you can collapse a piece of granite from the inside, hundreds of tons. ”

"And this kind of thing?" Zhang Zhitong was completely eye-opening today: "Then you mean that this concrete wall was damaged by a hydraulic splitter?"

"The principle is similar, but it's not a hydraulic splitter. ”

"The splitting machine is only suitable for breaking rock and pure concrete, and the plant is a reinforced concrete structure. Take it as an example because this kind of device is more widely used. ”

Ye Qing took out a drawing and said while drawing: "After the fragments you collected from the scene are restored, there must be some defects around the area that have become dust particles. ”

"There should be four to eight more of these holes around the perimeter of the concrete. It's just that the diameter of these small holes is too small, and after blasting, the traces are covered. ”

"They were supposed to use a hydrostatic blaster, with a round hole in the center where the blaster was placed. Then make a few small holes around it, so that the concrete will break and always stay within the range of the small hole construction. ”

Every time Ye Qing said a word, the eyes of these policemen brightened a little.

"That'...... Is this kind of equipment loud or not?" Zhang Zhitong asked with some excitement.

"The sound of the blaster is very small, and the hydraulic pump that provides it with dynamic and hydraulic pressure is divided into diesel engine and motor, and the diesel engine is louder, but if it is put in the car to work, the sound is not a problem. ”

"The reinforced concrete, after being broken by the pressure of the expansion from the inside outward, is still attached to the steel bar. As for the steel inside, you have detected it, and it was cut by fire. Ordinary steel bars are not much stronger than cream in the face of fire cutting. ”

"You can go buy one of these pieces and come back and simulate it. ”

Zhang Zhitong's beautiful eyes bloomed with indescribable joy: "Xiao Wang, you immediately contact the bureau and ask them to purchase a hydraulic static blaster." The model is bought according to the size of the round hole in the middle of the concrete after restoration. After the model is determined, a comprehensive visit to the equipment suppliers in the city is also required. Find out to whom the equipment has been sold in the last month. ”

The other policemen were all admiration and envy, so it was~So it was~

Hydraulic static blasters, they haven't even heard of them. But after Ye Qing introduced how it works. These technical policemen immediately had a feeling of enlightenment and enlightenment.

"Ye Ye...... In short, I wonder where you can buy this kind of software that automatically puts things back together in pieces?"

"This software is so powerful that it can restore broken concrete in a matter of seconds. ”

A male policeman wearing glasses said embarrassedly: "In our technical department, we often encounter criminals who smash and destroy the items involved. Sometimes when it is restored, it can torture people and want to hit the wall. ”

"It's no problem to give the software to you for free. ”

"But ......" Ye Qing's next sentence made these policemen have the idea of hitting the wall.

"But software doesn't work on your computer, and this software uses the rudeest and most accurate exhaustive algorithm. ”

"The more fragmented objects, the more the exhaustive algorithm eats up the hardware. Ye Qing pointed to the ground: "At your feet, there is a super server cluster composed of 10,000 server units. ”

"The super server cluster, it took billions to build, and it was just this super server, computing that software. ”

“……”

“…………”

A server built by one billion yuan, and the Zhongyun General Administration Branch was packaged and sold together, and it couldn't be sold for so much money.

What else is there to say, just praise Mr. Ye honestly in your heart.

"If you encounter similar problems in the future, you can contact the person in charge of the laboratory. The expressions of these policemen made Ye Qing very useful.

"Okay, let's move on to the next test. ”

Several male policemen nodded hurriedly and pushed the bulky safe over like a truck.

The cover inside the door of the safe has been removed by the police, revealing the password turntable structure and the mechanical locking structure inside.

The three internal wheel disc notches of the cipher disc have coincided together, and the horizontal lever on the latch falls into the notch.

"It looks like it was ablated by high temperatures. Ye Qing squatted down and carefully observed the two large coin holes on the main door of the safe: "Start the atomic absorption spectrometer, let's first analyze what foreign elements remain in this hole." (To be continued.) Your support is my biggest motivation. ):03:53
