Li Fei was stunned for a moment.

He didn't know about the glacier tunnel.

"I only know that this tunnel is very difficult to hit, but I don't know exactly where it is difficult, but I think with the current engineering level of the Dragon Kingdom, it should be able to do it, as long as all the projects are completed."

Li Fei said to himself.

Hearing his words, Tang Yuchen's expression suddenly froze.

It seems that Li Fei's evaluation of the glacier tunnel is only limited to the engineering level.

It is not an analysis of the situation inside the tunnel.

However, Li Fei's analysis is not bad.

Dragon Engineers can indeed create such tunnels, but it takes a lot of materials to make them like this and perfect.

But in the last days, the state is not yet able to withstand this attrition.

Therefore, if you want to build a flawless glacier tunnel, it is still difficult for the engineers of the Dragon Kingdom.

Of course, even so, they are confident that they will create a flawless tunnel.

"May I take the liberty of asking, why are you helping us with this?"

"I don't hide it from Captain Tang, I do want to help you, but our ability is limited, and we can't complete this project in the shortest possible time, and I don't know how far this tunnel can go."

"If you're really struggling, I can help."

Li Fei smiled.

"Captain Tang, I wonder if you're interested in joining the command center of the Special Office?"

Li Fei said what he thought in his heart.

"Join the Special Office?"

Tang Yuchen frowned.

She knew it was a rare opportunity, and if she missed it, she would regret it for the rest of her life.

"We can't promise you this matter for the time being, and we'll talk about it after we solve the problems inside the tunnel."

"Captain Tang, you have to think about it carefully, if you join us, I promise to give you a position as deputy commander, how about it?"

"This ......"

Tang Yuchen hesitated.

He didn't refuse Li Fei's proposal, but he was a little worried in his heart.

This is because the work in the command center of the special office is a top secret of national defense, and it is not available to ordinary people.

Tang Yuchen didn't dare to agree easily.

"Let's wait until we completely solve the problems inside the tunnel."

Tang Yuchen still politely rejected Li Fei's proposal.

Although Li Fei was a little disappointed, he did not blame Tang Yuchen.

"Since Captain Tang insists on this, I won't force it."

"But there is one thing I still have to remind Captain Tang, there are hundreds of tunnel openings in this tunnel now, if you dig once, if you don't get one right, the entire tunnel will collapse, and it may even cause a series of explosions."

"When the time comes, the tunnel will collapse, and you will be in great danger, are you sure you want to continue digging?"

Li Fei pondered for a moment and asked cautiously.

"If it were you, what would you choose?"

Tang Yuchen didn't answer Li Fei's question immediately, but asked.

"This ......"

Li Fei was silent for a moment, and then said, "If I were to do it, I would definitely choose to retreat without hesitation." After all, no one knows the situation inside the tunnel, and our people don't have any tools and facilities, so they rushed into the tunnel and just died in vain. I won't reopen the tunnel until I think of a way. ”

"What about your opinion?"

Tang Yuchen looked at the middle-aged man standing next to him.

"I also think Li Fei's suggestion is very reasonable, and I agree."

The scholar-like man said.

"Since everyone agrees with Mr. Li Fei's point of view, there is no need for us to continue digging, but we should find out the holes and the location of the holes in this tunnel as soon as possible, and then repair them to avoid causing huge disasters."

Tang Yuchen said.

"Captain Tang's method is very good. But Captain Tang, you also know that I don't have any experience in this area, so you should communicate with Mr. Li Fei, and we can get to know each other. ”

The middle-aged man said with a smile.

"Since everyone has no opinion, let's start now."

"Well, I'll give it a try."

Tang Yuchen nodded, and he took out a flashlight from his arms.

He carefully examined the structure of the tunnel, then took a flashlight and shone it deeper into the tunnel.

The tunnel is not deep.

In a few moments he saw the bottom of the tunnel.

There is a deep hole in it, and the stones inside have turned black.

Tang Yuchen used a flashlight to shine a picture around the hole.

Later, he found that there were many cracks around the hole, and there was a crack spreading from top to bottom.

Obviously, this place has been dug up before, and it has been dug up for a long time.

There were other people in this place who had been there.

Thinking of this, Tang Yuchen's heart couldn't help but feel a little more worried.

Tang Yuchen probed carefully a few more times, and finally determined this.

"Li Fei, there is a big pit here, and there are many cracks in this pit, obviously, the previous tunnel leads from this big pit. The tunnel we dug was dug from the other side of the tunnel, and although the two tunnels are very close to each other, I don't think there will be any chain reaction, and there should be no problem. ”

"Captain Tang, how many days have you been here?"

"Three days."

"Do you have anything to gain?"

Li Fei continued to ask.

"There is no gain, but our work is still going well, at least, we have completed a sixth of it."

"So much?"

Li Fei was slightly surprised.

He didn't expect that the excavation of the tunnel would be smoother than he imagined.

This came as a surprise to him.

"Yes, we're digging much faster than expected, and we're digging to a depth of about fifty centimeters. At this rate, it is estimated that in a day or two, we will be able to finish digging. ”

Tang Yuchen said with a smile.

"That's great."

"Well, I also hope that the tunnel can be built as soon as possible, in that case, it will also be of great help to our work."

Li Fei said.

"I'm sorry for you this time."

Tang Yuchen said with a smile.

"Captain Tang is polite."

When the two exchanged a few words, a team of people from the construction corps had already driven over.

At this time, others also came over.

They were also slightly surprised when they saw Li Fei.

Li Fei waved his hand.

"What do they do here?"

Tang Yuchen suddenly asked.

"We are soldiers."

Soldier?

Everyone was stunned.

"Yes."

"Are you doing anything dangerous here? I remember that your military region does not allow ordinary people to participate in the excavation of tunnels, right? ”

Tang Yuchen asked.
