After a lively dinner with the officers and soldiers stationed there, Lin Feng watched the shield machine start its return. The speed of the EPB is very fast when it is not digging, and it is a slow downhill road, so the speed exceeds 500 kilometers per hour.

In the tunnel with the flat ground, Lin Feng didn't feel much of this speed.

But soon he ran into the engineering team at the front, and when there were more people, he couldn't race at high speed. In the end, he simply drove the TBM to the return train and took a long ride.

After Lasa, there are two-way railroad tracks in the tunnel, all the facilities have been installed, and some of the ear holes have been stationed with soldiers, stacking all kinds of supplies.

It took more than a day for him to finally get out of the Rongcheng station.

In Rongcheng in mid-November, the weather is not too cold, and there are still people wearing shirts.

Political Commissar Li had received the news a long time ago and greeted his return with the commander-in-chief of the military region at the entrance of the cave.

"Thank you, Brother Lin," Political Commissar Li shook his warm hand, "I'm not allowed to go anywhere today, I'll be the east with Commander Hu!"

"I don't need to. ”

Lin Feng felt that eating with these two must not be very open.

"No, I must go," Political Commissar Li had no intention of letting him go, "not only to invite you to dinner, but also to pay you, unless you don't want to." ”

Well, Lin Feng felt that this threat was simply too big.

After 40 days of hard work, like a mouse, if you can't receive the money, it won't be a loss.

"And we have a couple of other projects to talk about. ”

Lin Feng almost ran away when he heard this, and he didn't let people stop, so he only came out of the ground for a few minutes.

And a few more.

He felt that he had to find a few reliable people to drive the TBM immediately, otherwise his future days would be doomed.

The group came to the private room of the military canteen, and all kinds of exquisite dishes exuded attractive aromas.

Lin Feng didn't eat less meat along the way, but now he was a little tired when he saw the meat, and he kept attacking a plate of green oily wheat vegetables.

"Brother Lin, it's really hard for you this time," Political Commissar Li said again, "With this tunnel, our western side is in a certain situation." ”

Commander Hu was originally a person who didn't talk much, but at the moment he was also smiling and said a bunch of words of thanks.

The successful opening of the tunnel is a great good thing for the country and the family, and it is like a stroke of genius for the military region. In the future, there will be no problem with resource mobilization, and it will be even more convenient for him to deal with matters on the border.

"It's just that the west is opened, and there are still ...... in the north and south"

"Political Commissar Li," Lin Feng interrupted him very unceremoniously, "can we discuss it later?"

"Haha, no problem, no problem," Political Commissar Li laughed twice, "But the line from Rongcheng to the capital must start immediately!"

Lin Feng almost didn't choke to death from a mouthful of vegetables.

According to Political Commissar Li's meaning, the whole country has to build tunnels on the left and right. This may not be the end, in the future, the city's subway, city-to-city transportation, may most of the subway will be replaced by the subway.

The advantages of underground tunnels are too obvious, they are safe, reliable, fast to build, and even reach unprecedented speeds. Maybe you can go to the capital from Rongcheng in the future, and you can get there in less than an hour.

It's a huge system project.

"Brother Lin, Mayor Qin came to me a few days ago, and he is still in a hurry to build a subway," Political Commissar Li said, "Look at a machine like yours, can you produce a few more?"

How many?

Lin Feng shook his head again and again.

The cost of this thing is too high, and it won't be used for a few years after 3.5 billion is bought, and it's a waste to buy more.

"Political Commissar Li, resources are limited, I can produce up to two. ”

Political Commissar Li and Commander Hu glanced at each other, and they both felt a relaxed look in each other's eyes.

Although the TBB is not a weapon for direct attack, it is a strategic weapon. If Lin Feng can produce in large quantities without limits, and then dig holes all over the world, then the earth will be in chaos.

"Okay, when will it be produced?" Commander Hu asked, "We are in a hurry!"

"Tomorrow the day after tomorrow. ”

Commander Hu choked on his trachea with a sip of tea and kept coughing. Political Commissar Li has already learned Lin Feng's trick, so he is quite calm at present.

"But in the future, I will not participate in tunneling, I can train drivers. ”

"That's fine. ”

Political Commissar Li wished that such a machine could be in the hands of the state, and everyone could rest assured.

"Okay, I'll send you 6 people, do you see enough?"

Lin Feng nodded, the shield machine can be automated, as long as the program is set up, there is no need to worry about it, at most, it will look at the energy loss, or in case of emergency, it will be operated.

And he is not worried about the shield machine being occupied by the state, as long as he is connected to the remote control, he can make the shield machine obey his command at any time.

"Then it's decided, when do you think the training will start, what are the requirements for the driver, and how long will the training take?"

"Since you're in a hurry, let's start after eating, find a few random people, and we'll be taught in half an hour. ”

Political Commissar Li and Commander Hu were once again speechless: Is this high-tech? Isn't it a high-tech thing, and it has to go through a long period of theoretical knowledge and simulated operations before they can take up their posts?

How can it be said in Lin Feng's mouth more simply than driving a tractor?

"By the way, there's one more important thing. Political Commissar Li said, "Academician Sima has urged me several times, saying that there is something important to look for you, I have just informed her, and it is estimated that I will be there later." ”

At this time, Commander Hu said with a smile: "Little brother Lin Feng, this time you have really contributed to the country!"

Lin Feng was puzzled, what kind of hard work?

Commander Hu didn't say much, but he could see that he was in a really good mood.

After some small talk about the topic, Political Commissar Li arranged for six people to come over. They are all people in the team led by Li Guangping, and they are familiar with Lin Feng.

It took more than ten minutes, taught them how to operate, and let everyone try to open it again, and then it was done.

He then gave two of them permission to operate.

Political Commissar Li and Commander Hu couldn't wait, and immediately put the shield machine into work, and not far from the mouth of the tunnel to the west, they began to plunge into the earth headlong to the northeast.

The program Lin Feng has set in advance, so just send out the start command.

The tunnel is only more than 1,700 kilometers long and can be opened in the early twenties, and the price Lin Feng still intends to keep it the same.

Looking at the semicircular tunnel that formed quickly, Political Commissar Li and Commander Hu were in a relaxed mood like a clear clear sky, and then immediately notified the ministry to settle the bill for Lin Feng.

33 billion arrived soon, looking at the long list of 0s on the short message, Lin Feng finally breathed a sigh of relief.

How money is earned, it has to be like this, tens of billions of billions, which is refreshing enough.

Then he ordered two more TBMs, this time without transmission, and let the courier company deliver them directly to the gate of the station tomorrow.

The matter here came to an end, and Lin Feng saw the dusty Academician Sima Lili again.

"Long time no see. Sima Lili took the initiative to shake hands with him, this was the first time.

"Yes, it's been more than a month," Lin Feng said with a smile.

The two walked to the workshop, Lin Feng saw a car parked at the door, covered with a canvas, and couldn't help but be curious, Sima Lili asked people to uncover the canvas.

It's actually a tank!
