A radial hole two fingers wide was clearly visible on the stainless steel cabinet door that was intact, smooth and flat a few dozen seconds ago.

The edge of the hole was covered with spider-web-like cracks, and the steel plates penetrated seemed to be popcorn that had just been out of the pot, rolling upwards to the inside of the cabinet at a strange angle.

The front end of the electromagnetic gun, which is used as the gun barrel, has turned black and gray, and the burning marks are clearly visible.

Liang Yuan and the two girls stared at each other for a long time, before they recovered from the shock, several muffled screams and scoldings came from the filing cabinet.

"Who did this? There is still a large group of people in the house. Are you planning to demolish the house or what?"

The three of them looked at each other and hurriedly ran to the near the filing cabinet and opened the punched cabinet door. Liang Yuan found that not only the cabinet door of the filing cabinet and the cabinet body behind the filing cabinet were penetrated at the same time, but also a two-finger-wide hole was also made into a color steel insulation wall behind the filing cabinet.

The workshop Zhou Heng found for Liang Yuan was the office building of the Administrative Department at the time of the Science and Technology Park being built and opened.

With the expansion of the scale of the science and technology park, the office equipment of the administrative department has increased sharply, and the office area is becoming increasingly tight.

After the completion of the gas turbine workshop, in order to alleviate the dilemma of insufficient office area of ​​the administrative department, Li Yuanling and Huachen's staff moved directly into the newly built gas turbine workshop and gave the four floors he used to the administrative department.

The administrative department that obtained the new office building finally breathed a sigh of relief. There was no need for two people to squeeze into the same desk to work. After the administrative department moved out, the old building was used as a warehouse by the administrative department to store daily office supplies, labor protection supplies, holiday benefits and other miscellaneous things.

In order to increase the use area, the administrative department demolished most of the non-load-bearing walls of the building and used ordinary heat-insulated color steel to make several partitions, which was considered to have built this simple warehouse.

The so-called color steel insulation wall is commonly referred to as a thick insulation board between two iron sheets. This thing can bend with an adult with his feet, and it has nothing to do with his strength.

Looking at the big hole in the color steel insulation wall, Liang Yuan was frightened. He didn't expect that someone would kill him. After this electromagnetic gun superconducting, he had such great invasion power, and he might have a life of death.

He didn't care about cursing from the other side, Liang Yuan put his head into the filing cabinet and shouted into the bullet hole: "Is anyone injured?"

An angry eye suddenly appeared at the other end of the bullet hole, which scared Liang Yuan.

He suddenly looked up and Liang Yuan forgot that he was in the filing cabinet. With a bang, he hit the file partition firmly on his head, causing someone to grin and suck in a cold air.

"You did it? You are so capable. You can even make the drill bit fly if you use an electric drill to drill holes. Do you know if you almost hurt someone just now?"

It was obvious that the person on the opposite side had not figured out the situation yet, but in terms of the situation on the scene, although the thing that was like a broken drill bit was bare and looked very strange. But except for this reason, ordinary people really couldn't think of what could make such a big hole in the wall.

Hearing that he didn't hurt anyone, Liang Yuan relaxed and his originally beating heart gradually calmed down.

"Uncle, uncle, I'm very sorry, very sorry. I'll go over and apologize to everyone." Liang Yuan smiled flatteringly.

He and the two girls who were slightly shocked came out of the door. After turning two bends along the building, Liang Yuan entered the building from the main entrance.

In the corridor, there were three or four employees of the administrative department looking around. When they saw Liang Yuan and two girls walking in, waved to the three of them, turned around and returned to the room.

Liang Yuan walked into the next door of his workroom but was shocked. There were more than 20 people in the room of hundreds of square meters, all concentrated in the right half of the room, and it seemed that he was collecting something.

On the left side of the room is a hole just made by the electromagnetic gun. The aluminum warhead that caused the accident was unrecognizable and placed on an office desk. At first glance, it looks like the abandoned iron slag next to the blast furnace of a steel mill, no longer as smooth and neat as it had been a few minutes ago.

Before Liang Yuan could apologize, several names such as "Big Young Master" and "Yuan Da Jun" appeared in the crowd.

For employees of the Science and Technology Park, Liang Yuan may not be recognizable. At first glance, he looks no different from an ordinary boy next door, but the two girls are so easy to recognize.

Twins with such a high similarity, let alone the Science and Technology Park. Even if they are thrown in Shengjing or the whole province, they may not be able to find similar examples.

As the establishment of the science and technology park increased and the number of exchanges with local Benxi companies such as the Northeast Locomotive Factory, the childhood sweethearts and messy things that Liang Yuan and the two loli were finally slowly spread in the science and technology park.

Even if you have never met Liang Yuan, you can tell from the information you get from your usual chat that most of the teenagers who can stay with two girls are undoubtedly Liang Yuan.

"Well……."

Liang Yuan, whose identity was exposed, blushed and kept saying that he had done it, and he was the first time he was operating the equipment. I'm sorry to everyone.

Although no one knew that Liang Yuan was Yuanjia’s boss, Li Yuanling’s son’s signature was very useful. In the eyes of ordinary employees, the smart and capable, Mr. Li, who was the boss of the Science and Technology Park, was the boss of the Science and Technology Park.

The uncle who showed one eye just now angrily scolded Liang Yuan and laughed, saying a few words like "be careful of safety and equipment" fooled the matter.

However, when Liang Yuan was about to go out, Xu Xiaohe, the head of the warehouse, asked curiously how the electromagnetic gun that Liang Yuan participated in the Qingke Competition was doing.

Liang Yuan’s workshop was what Zhou Heng asked Xu Xiaohe for the name of Liang Yuan participating in the Youth Science Competition. There was no need to hide someone’s products. Xu Xiaohe asked Zhou Heng casually and knew that Liang Yuan was going to get an electromagnetic gun.

There were all the evidence and evidence, and there was a worse file cabinet next door that was not processed. Liang Yuan did not hide the truth. He smiled bitterly and said, "Aunt Xu, I made the hole in the wall with an electromagnetic cannon."

As soon as Liang Yuan said this, the air in the room stagnated. Liang Yuan, who knew that there was something wrong, said sorry and bowed, and fled in panic with two girls, sneaked out of the warehouse.

I went to the administrative office to find Zhou Heng to arrange someone to change the color steel insulation wall, remove the superconducting coil of the electromagnetic gun and put it away. At night, I went to the joint camp with two girls who were just as guilty as they were, and went shopping with dinner. It was not until nine o'clock in the evening that the three of them wandered back to the 909 community.

Liang Yuan opened the door and saw that Li Yuanling was indeed sitting in the living room, looking at the three of them with a stern face.

"Uh, mom came back so early today."

"Yeah yeah."

"Aunt Liang hasn't come back so early in a long time."

The two girls also followed Liang Yuan and had nothing to say.

Li Yuanling looked at the three of them like fat-headed fish that had made a big mistake, and tiptoed into the sofa opposite him and sat down. Then she looked like I was wrong and you were criticizing casually, and finally couldn't continue to maintain a serious expression.

He glared at Liang Yuan with a laugh and cry, and said with some hatred: "Jia Jia and Feifei don't often play with those strange things. I don't know that it's understandable. My mother has told you since she was a child that no matter what you invent or test, safety is put first. Do you regard your mother's words as a breeze in your ears?"

Liang Yuan stayed honestly on the sofa and nodded sincerely to admit his mistakes, admitting that he was not considerate.

How could the two girls not hear Li Yuanling's tone relaxed, and they smiled and leaned beside Li Yuanling, holding Li Yuanling's arm half-slapped and acting coquettishly. As a result, it took only five minutes to fool the dangerous accident.

"Mom. Before I prepared the superconducting coil, I had already used the BVR4.0 copper coil as a reference for data. According to the data I calculated, the aluminum bar can only barely be injected into a coin. How can I change it to a superconducting coil and the effect is so exaggerated?" Liang Yuan asked curiously.

Li Yuanling thought for a moment and said with a smile: "Xiaoyuan must not consider the loss and heat generation of copper wire when calculating. For a capacitor with a constant capacity, the loss and heat generation of copper wire will consume 30%-50% of the energy carried by the capacitor, and the magnetic field strength generated is far lower than the calculated value in the ideal state. After Xiaoyuan switches to superconducting coils, this loss is almost negligible. The significant increase in the magnetic field strength is the reason why the electromagnetic gun loses control."

Liang Yuan patted his head and finally realized that the superconducting wire rolled by the three people was one millimeter thick and two millimeters wide, and the maximum carrying current value could reach 40A. It is twice that of the BVR4.0 copper wire. It can be said that the superconducting wire only uses half of the cross-sectional area of ​​the copper wire, carrying twice its current and without any loss.

After Li Yuanling reminded Liang Yuan, he realized that if the superposition effect of the magnetic field is taken into consideration, after the coil is replaced with a superconducting wire, the power in the capacitor will be almost wasted, and the throughput capacity of the electromagnetic gun will be increased by at least three times. It is reasonable to break through the file cabinet and the wall in this way.

"Superconductors are a good thing. Take the motor as an example. If the coils inside are all made of superconducting wires, the basketball-sized superconducting motor is enough to drive the Haishi van in the Science and Technology Park. Unfortunately, the research of superconducting is like finding a needle in a haystack without any clues." Li Yuanling said with emotion.

The next day, Liang Yuan and two girls were busy in the workshop for a day and removed several pieces of the capacitors of the electromagnetic gun, greatly reducing the system power of the electromagnetic gun. After all, this thing was taken out to participate in the science and technology competition, rather than participating in the arms bidding meeting.

With the current power of electromagnetic cannons, they are almost caught up with the sniper rifle in a short distance. How could Liang Yuan wander around with such a dangerous thing?

In the evening, the three of them went to the canteen of the Science and Technology Park for dinner as usual, but Liang Yuan strangely discovered that many employees of the Science and Technology Park looked at them with strange eyes.

After thinking for a while, Liang Yuan didn't get the point, so he had to put this question aside and discuss with the two girls to find several materials for testing, compare the performance of the yttrium barium copper oxygen superconducting coil currently used, and complete the last part of the competition project book.

"Xiaoyuan, what materials should we find for comparison and experiments? Is there any Dongda?" Ning Wanfei asked curiously.

"My sister Zhou Qian, who guided us, said that the superconducting materials we have discovered now will not exceed ten fingers. Which one should we use for the experiment in Xiaoyuan?"

"Neither of you noticed that Zhou Qian's words is a superconducting material with practical value. In terms of the situation in nature, about one-third of the elements can show superconducting characteristics at a certain temperature and pressure. For example, the first superconductor discovered by humans is mercury, but the transition temperature of mercury is too low and has no practical value."

"It can be said that whenever we find a substance, we have a chance of more than 30% to make it reach the superconducting state." Liang Yuan concluded finally.

Seeing the two girls nodding suddenly, Liang Yuan smiled and said, "We will go to the physics laboratory or chemistry laboratory of Dongda University to find five substances tomorrow, and then take them back to the superconducting center for experiments. If you are not very lucky, both superconducting and non-superconducting materials should be included, so that we can complete the last step of project development."

After hearing Liang Yuan say this, the two girls breathed a sigh of relief and said together: "I have been busy for more than half a month, and I am finally going to finish it."

After dinner, the three of them planned to go back early to rest and take good care of the experiment the next day.

It was still Zhou Heng who drove the sea lion to pick up and drop off Liang Yuan and the two girls, but after getting in the car, Liang Yuan found something was wrong. Zhou Heng always looked at himself from the rearview mirror with a smile on his face.

Liang Yuan asked curiously and found out that the incident of digging holes in the wall was under the rumor that the three of them became tigers. The accident has spread throughout Nanhu Science and Technology Park.

Some storytellers even saw the electromagnetic cannon that had mostly blackened the PE tube, and then made a very appropriate joke for the accident - the black-faced, black-skinned bully, who caused a disaster and knocked down the wall.

Looking at the two girls who were laughing and beating, Liang Yuan sighed helplessly and said angrily: "Who made up this joke? I and him are not finished. Young Master, my skin is extremely healthy, so how can I describe it as black?"

However, someone was a little happy when he thought about it. Fortunately, people are relatively simple these days. If you put this on those unconventional guys in the new era, you will probably blow the wall and make the bed collapse.
