In the main control room of the No. 1 transportation channel, more than a dozen engineers took lighting equipment and maintenance equipment and began to inspect the track lane that transported aircraft, ammunition and other items from below the mountain.

At first, everyone thought it was a simple circuit failure, but after a walk around, they did not find any results. The headquarters required that the tracks be resumed quickly and all subsequent arms must be transported on time.

This mountain project is already very large. There are four large engineering areas in the mountains on this side, and there are several large tunnels that are several kilometers long or even ten kilometers long, specifically used to transport goods from the bottom of the mountain. This leads to insufficient professional engineers and technical jobs, and it is necessary to find some skilled people from the workers.

There was no problem in the first maintenance, and the main control room started the circuit equipment again. However, less than a minute after running, the circuit tripped again and automatically entered the safe protection mode.

This made the main control room very anxious. They immediately vented the management unit and asked them to find a few workers who knew the circuit to help. Because the superiors were urging them to send this batch of arms to major platforms on time, the tracks must resume operation, otherwise it would be too slow to transport them by manpower, and the second was that the time was too slow and the movement was too loud.

...

It was past two o'clock in the morning.

As soon as they finished eating dumplings, they sat in the small project room, chatting in a low voice, and were called out by the officers and rushed to Tunnel No. 1.

This is the first time that workers in the No. 1 and No. 2 worker entered the No. 1 Tunnel that transported arms. Because this place was first completed, the group of people working here had been transferred, and later it was limited to internal personnel.

Because the matter was urgent and the upper floor kept urging, everyone was immediately divided by the engineer after they came in and inspected and repaired the circuits according to the section.

This tunnel is not parallel, but a large slope, from the bottom of the mountain to the hillside, with a total length of about twelve kilometers.

At this moment, the circuit board of the main engineering room showed that the No. 6 section had a fault, but this section alone was two kilometers long, so everyone was scattered and sparse.

After more than forty minutes of inspection, an engineer and a worker finally found a problem in a disposal box.

Some water stains in the distributor box are soaked in the converter, which leads to a short circuit and tripping.

After hearing this news, the head of the main control room irritably scolded the manager in charge of this area, saying that they did not even have basic common sense. There is cold air in the mountain, and heat will be generated when the power distribution box is working, which may melt some frost, causing some water stains and water vapor. Therefore, moisture-proof and waterproof treatment should be the top priority, but they neglected it.

The manager was scolded very wronged because he remembered that the moisture and waterproofing projects here were done very carefully, and this kind of short circuit problem would not occur under normal circumstances. Moreover, the water stains in the distribution box were also a bit large and concentrated, and it didn't look like the frost was melted...

However, the upper level was urging us to restore power supply as soon as possible, so everyone did not argue about this matter for the time being. They only quickly dealt with the fault and were ready to discuss it when they were idle.

But what the main control room did not expect was that the fault of the power distribution box was solved, and the power supply system still did not recover, and there was no reaction like when the trip was started.

For example, the light flashes, sparks appear on the main power box, but after the main switch is turned on, the power supply system has no response.

At this moment, the director of the main control room could not sit still and immediately took a car to the scene to check it in person. But after running around, he came to a conclusion that the power supply system might have been activated a few times, resulting in the safety system being overloaded several times, and some lines burned out.

If it is just a trip or a fault, then check and repair the main control electric boxes and the power distribution box. But if the circuit is about to burn, then you won’t know where the problem is happening.

This tunnel is crucial and has backup circuits, but the battery life is not long and it cannot bear such a heavy workload alone. In addition, the top-level unit has issued a dead order and must finish the work here before a specific time tomorrow, so the officer in charge of District 1 has no choice but to call Li Zhixun.

"Hey, Chief Li, something went wrong with Tunnel No. 1," the officer said in a weak voice: "It may require a large-scale maintenance, and some lines must be dug out. Now there is not enough manpower, so we have to transfer workers to come."

Lee Chi-hoon frowned and asked, "What did you do?"

"...Mountain engineering, anything can happen." The officer replied softly: "I also criticized the people in the control room, but they had a lot of reasons. These people were very arrogant and unhappy. If they didn't work, it would be even more troublesome."

"Okay, you can go and transfer workers, and quickly repair them. You must finish the work before the specified time tomorrow."

"good!"

The two of them finished communicating and the call ended.

In the tunnel, Meng Xi looked at Jiang Xue, gestured at the electric melting gun in his hand, and nodded slightly.

...

Half an hour later, the workers in charge of Areas 1 and 2 were pulled out, and Lao Qiao, He Dachuan, He Qiang and others were all among them. Because they might have to check the entire 12-kilometer section, there were as many as 150 workers pulled out.

Inside the No. 1 Transport Tunnel.

Old Qiao rubbed his face, yawned and said, "What's going on? Why did we get into this tunnel?"

Jiang Xue glanced around, stood beside Lao Qiao in a low voice and said, "Do it in advance."

"What should I do in advance?" Lao Qiao was not very familiar with him because Jiang Xue was not in his dormitory. The two sides communicated with each other and rely on other workers to pass messages.

"That agreed thing must be done in advance." Jiang Xue repeated.

Old Qiao frowned and turned his head to look at Meng Xi.

"We really have to do it in advance." Meng Xi also came over and said, "A lot of big platforms have brought planes, and the other party may have to do something."

Lao Qiao looked at them and said lightly: "What does it have to do with us when I pulled the plane? The agreement between me and others is the seventh day of the lunar calendar, and it cannot be changed."

"We must do it in advance." Jiang Xue repeated.

Old Qiao looked at the two of them: "What do you mean?"

"Don't gather together, work quickly!" The person in charge of the main control room waved his hand and shouted: "Follow the sections and drawings to check the lines, hurry up!"

The workers slowly dispersed. Old Qiao glanced at Jiang Xue and whispered: "Don't fucking messing around, this matter involves many brothers... Don't cheat people."

Jiang Xue turned his head and looked around: "If you don't do it, we will do it alone."
