Monster Factory

Chapter 453: Solving the Mystery

On the huge display, a block of concrete digital models was scanned line by line and the messy concrete fragments suddenly turned into a digital virtual three-dimensional map. This made Zhang Zhitong and the other policemen stare wide-eyed. When their technical department would do deal with such advanced equipment?

After ten seconds, the modeling was complete.

Just as the police were wondering what the next step was, these messy concrete fragment models flew on the big screen.

"Model calculation... 5%... 55%... 100%..."

As the progress bar moved quickly, these broken models were magically combined one by one. It was like a digital wall, which was broken and restored. When the progress bar had reached one hundred, the original messy and broken virtual model had become a square, a virtual concrete wall covered with cracks. The whole process took less than a minute.

The policemen’s eyes widened again because the recombined virtual wall could clearly show there was an irregular deep hole the size of a potato chip bucket in the center.

There were many defects around the deep hole that were broken into particles and could be unrestored. But this did not prevent people from intuitively judging this was a circular deep hole with cracks in the concrete that have spread from around the deep hole in the form of a net. It was like a car glass, the kind of crack shattered by a bullet.

"Hiss..."

The policemen took a breath. Could it be said that this wall was broken by armor-piercing bullets?

How loud was 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: "Moreover we also did not detect any traces of gunpowder on the concrete fragments."

"It’s not the impact of a high-speed object." Ye Qing carefully looked at the restored three-dimensional simulation map and explained: "If I guessed right, this should be the principle of static blasting. It is not the kind of blasting that everyone knew, it is the use of mechanical energy to explode hard objects, rocks and concrete have extremely high external compressive strength, but the internal outward tensile strength is poor. If the external compressive strength is 100, the internal strength is only 2 to 10. A hydraulic splitting machine, I don’t know if you have seen it before?"

"For mining stone, you only need drilling 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 such a thing?" Zhang Zhitong was completely eye-opening today: "Then you mean, 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 rocks and simple concrete, and the factory building is a reinforced concrete structure. Take it as an example because this kind of equipment is more widely used."

Ye Qing pulled out a drawing-paper and said as he drew: "After you restore the fragments, you collected from the site, and there must be some defects in the surrounding area that turned into dust particles. There should be four to eight small holes drilled around the concrete. It’s just the diameter of these small holes is too small, and maybe as thick as a pencil. After blasting, the traces are covered. They should have used 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 cracking in the small holes but in the scope of construction."

Every time Ye Qing was saying a piece of information, and the eyes of these policemen became brighter.

"Then...Is this equipment loud?" Zhang Zhitong asked with a little excitedly.

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

"The reinforced concrete, after being crushed by the expansion pressure from the inside was also connected to steel bars. As for the steel bars inside, you have to detect them and cut them with fire. Ordinary steel bars are not much stronger than butter before fire cutting. You can buy one of these equipment and come back to simulate it."

Zhang Zhitong’s beautiful eyes filled with unspeakable joy: "Dear Wang, you immediately contact the bureau and ask them to purchase a hydrostatic blasting machine. The model is based on the size of the round hole in the middle of the concrete after restoration. After confirming the model, we have to visit the equipment suppliers in the city to find out to whom this equipment has been sold during the past month."

The other policemen had admired, and they were envious. They had never heard of a hydrostatic blasting machine, but after Ye Qing introduced its working principle. This group of technical policemen immediately had a kind of enlightenment, and suddenly felt enlightened: "That’s it~ that’s it~."

"Mr. Ye... In general, I don’t know where I can 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 often encounters criminals, smashing and destroying the items involved. Sometimes the restoration can give the impression for the person being blind in front of a wall."

"It’s okay to give the software to you for nothing... But..." Ye Qing’s following sentence made the policemen think about hitting the wall.

"But the software won’t run on your computer. This software uses the rudest and most accurate exhaustive algorithm. The more fragmented objects, the more the exhaustive algorithm will use the hardware." Ye Qing pointed to the ground: "Under your feet, there is a super server cluster consisting of 10,000 server units. The super server cluster took billions to build it. It was just this super server that was computing the software."

"..."

"..."

A server built by a billion Yuan cannot be bought even if they would pack and sold the branches of the China Cloud General Administration, they could not have so much money. Monster Heavy Industry and Mr. Ye were really bullish, not bragging. If there was anything else to say, just praise Mr. Ye from the heart.

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

"Okay, let’s start the next test."

The policemen nodded quickly and pushed the bulky safe over like pushing a truck. The cover plate 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 a high temperature." Ye Qing squatted down and carefully observed the two holes the size of two coins on the front door of the safe: "Turn on the atomic absorption spectrometer, let’s first analyze what foreign elements are in the residual hole."
