Monster Factory Chapter 553: : Crack the mystery

On the immense monitor, a digital model of concrete blocks are scanned line by line.

The messy concrete debris suddenly turned into a digital virtual 3D map. This made Zhang Zhitong and the other policemen stare wide-eyed.

When did their technical department deal with this advanced device?

After ten seconds, the modeling is complete.

Just as the police were wondering when the next step would be, these messy concrete fragment models flew on the big screen.

"Model calculation..."

"5%...55%...100%..."

As the progress bar moves quickly, these broken models are magically combined one by one.

Like a digital wall, it is broken and restored. When the progress bar reached one hundred, the original messy and shattered virtual model had become a square, a virtual concrete wall covered with cracks. The whole process took less than a minute.

The police glared a little bigger again, because the virtual wall after the recombination can be seen very clearly, with an irregular deep hole the size of a potato chip bucket in the center.

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

Concrete cracks spread from around the deep hole in the form of a net. It's like a car glass, the kind of fissure shattered by bullets.

"His..."

The police took a breath. Could it be that this wall was shattered by armor-piercing bullets?

How loud is that, and how bold?

"If it is hit by a high-speed object, the passage created by the gangster on the wall should be circular. But the passage left on the scene is obviously square." A police officer in the trace inspection room said in a low voice: " And we did not detect any traces of gunpowder on the concrete fragments."

"It is not a high-speed object impact." Ye Qing carefully looked at the restored 3D simulation diagram and explained: "If I guessed right, this should be the principle of static blasting."

"It is not the kind of blasting that everyone understands, but the use of mechanical energy to blast."

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

"Hydraulic splitting machine, I don't know if you have seen it before?"

"For mining stone, you only need to drill a few small holes, put the splitter into the hole, and in two minutes, you can collapse a piece of hundreds of tons of granite into two pieces from the inside."

"There is this kind of thing?" Zhang Zhitong is considered to be a complete an eye opener world today: "Then you mean, this concrete wall was damaged by a hydraulic splitter?"

"The principle is similar, but not a hydraulic splitter."

"The splitting machine is only suitable for breaking rocks and simple concrete, and the factory building is a reinforced concrete structure. Take it as an example because this device is more widely used."

Ye Qing took out a drawing and said as he drew: "After restoring the fragments you collected from the site, there must be some defective parts around it that turned into dust particles."

"There should be four to eight small holes drilled around the concrete. The diameter of these small holes in merely is too small, and may be as thick as a pencil. After blasting, the traces are covered."

"They should be using a more advanced hydrostatic blasting machine. The big round hole in the center is used to place the blasting machine. Then a few small holes are punched around to keep the concrete from cracking. Within the scope of the small hole construction."

Every time Ye Qing said, the eyes of these policemen became brighter.

"Then...Is this device sound loud?" Zhang Zhitong asked a little excitedly.

"The sound of the blasting machine is very small. The hydraulic pump that provides hydraulic pressure to it is divided into diesel engine and electric motor. The diesel engine has a louder sound, but if it is used in a car, the sound is not a problem."

"Reinforced concrete, after being broken by the expansion pressure from the inside, is still connected to steel bars. As for the steel bars inside, you have detected that they were cut by fire cutting. ordinary steel bars are not much stronger than butter before fire cutting. ."

"You can buy an device of this kind, and come back to simulate it."

Zhang Zhitong’s beautiful eyes burst with unspeakable joy: "Xiao Wang, you immediately contact the bureau and ask them to purchase a hydrostatic blasting machine. The model is based on the restoration of the circle in the middle of the concrete. After confirming the model, we have to visit the device suppliers in the city to find out who the device has been sold to in the past month."

The other policemen admire and admire it, so ~ is so ~

Hydraulic static blasting machine, they have never even heard of it. But after Ye Qing introduced its working principle. This group of technical policemen immediately felt enlightened and suddenly enlightened.

"Ye Ye...In general, I don't know where can I buy this kind of software that automatically puts broken objects back together?"

"Your software is too strong. It can restore the broken concrete in a few seconds."

A male policeman wearing glasses said embarrassedly: "Our technical department~IndoMTL.com~ often encounter criminals who smash and destroy the items involved. Sometimes it can be restored, which can make people want to hit the wall."

"It's okay to give the software to you for nothing."

"But..." The following sentence from Ye Qing made the policemen think about hitting the wall.

"But the software won't run on your computer. This software uses the most rude and most accurate exhaustive algorithm."

"The more fragmented objects, the more the exhaustive algorithm eats up the hardware." Ye Qing pointed to the ground: "Under your feet, there is a Exceed Grade Server Cluster composed of ten thousand server units."

"Exceed Grade Server Cluster, it took billions to set up. Just now this Exceed Grade server is computing that software."

"..."

"..."

A server built for one billion yuan, packaged and sold together with the branch of the China Cloud General Administration, can not sell so much money.

Monster Heavy Industry and Mr. Ye, that's true, not bragging.

What else can I say, I honestly praise Mr. Ye then it will be alright.

"If you encounter similar problems in the future, you can contact Person-in-Charge in the laboratory." The expressions of these police officers made Ye Qing very useful.

"Okay, let's start the next test."

Several male policemen nodded quickly and pushed the heavy safe over like a truck.

The cover inside the safe door has been removed by the police, revealing the cipher dial structure and the mechanical locking structure inside.

The three wheel disc gaps inside the cipher disc have been overlapped, and the horizontal lever on the latch fell into the gap.

"It looks like it was ablated by high temperature." Ye Qing squatted down and carefully observed the two large coin holes on the front door of the safe: "Turn on the atomic absorption spectrometer. Let's analyze first. In this hole, there is Which foreign elements remain." (To be continued.)
