Treasure Island was completed, the airport construction plan was put on the agenda, and Chen Nian, who was far away in China, finally breathed a sigh of relief.

Things at sea have finally completely subsided, and after that, for a long time, it should not be able to set off the wind and waves.

The reason is simple.

The combination of J-20B + island-building is really too strong.

The launch of the Sky Whale nearly 10 years ahead of schedule and the fact that its performance has almost doubled means that now that the United States is mired in the war on terror and temporarily unable to touch the South China Sea, we have more time and more space to operate at sea.

The cost of building islands has been greatly reduced, and in a very short period of time, we can build one "leapfrog" island after another in the Xisha Sea.

Of course, no matter how well funded they are, it is unlikely that each of these islands will be built into a large island with an airport, various infrastructures, and even living quarters like Yongxia Island in later generations.

Most likely, the islands have helicopter take-off and landing capabilities, and some islands have harbors for small boats, which can be used to sustain themselves at a basic level.

Originally, according to such a design, in fact, the deterrence capabilities of these islands were insufficient.

But the problem is that everything changed when the J-20B began to be deployed to the Paracels.

The range of activities of the Air Force has expanded from one island to a group of islands.

And the enemy's means of striking are also greatly weakened in terms of effectiveness.

Yes, if there is only one Yongxia Island, then you can easily destroy it with a saturation attack, and after this nail is removed, our control over the South China Sea will be reduced.

But now we don't just have Eternal Summer Island, not only Treasure Island, but also a series of smaller islands.

What, are you going to blow them up one by one?

As long as we can't blow up in the first wave of attacks, then our air supremacy will not be completely lost.

Because, in an emergency, our J-20B can take off from any of the islands!

This is the difference between an aircraft carrier and an "aircraft carrier system".

Otherwise, why does the US have to build a two-carrier battle group every time it moves in earnest?

Quantity, at some point, will also be the key to solving the problem

Quantity, quality

Chen Nian suddenly thought that the J-20B deployed to Treasure Island was not yet complete, and its range was still too short.

However, once the variable cycle engine on the 611 side is born, its combat effectiveness can be qualitatively improved.

The combat radius of nearly 1,000 kilometers can cover almost the entire Southeast Asian peninsula.

When the time comes, in the most extreme cases, it is not impossible to touch India

Thinking of this, he smiled with satisfaction.

In fact, when he first conceived the STOVL fighter, he made this plan.

Now, nearly two years later, this goal has finally been achieved.

On the whole, this set of scientific and technological progress has also brought him a lot of returns.

Now, the number of source points of his average daily growth has broken through the 0.3 mark for the first time, and it has maintained this number for a week in a row.

While there will certainly be volatility after that, it's a huge step forward.

And the total number of source points he holds in his hands has also reached an astonishing 16 points.

It's time to kickstart your next steps.

He needed a large, yet modularly decomposed, project to consume these source points.

Chen Nian frowned, and he glanced at the schedule.

Tomorrow is the regular working meeting of the Spark team, and it is a good opportunity to understand the progress of each project.

These include the ongoing Deep Blue 16 project, the Rainbow-8 UAV project, the H-20 project, which has been launched in cooperation with Russia, and the high-speed rail project, which has completed the construction of the first trainset and is ready to start testing

During this time, I actually invested in these projects, but they were basically scattered.

This shows that these projects have indeed not encountered key technical difficulties, and there is no need to do it themselves for the time being.

Or maybe there is some problem, but the people in charge of the project think that it is too cost-effective to involve themselves.

If that's the case, then you'll have to re-analyze it.

By following the prompts of the Task Manager, you may be able to invest more resources in certain key points to speed up the progress of technology development

Chen Nian put away his somewhat scattered thoughts and glanced back at the time.

It's time to get out and about again.

At this time, Xi'an University of Technology had already gone home during the summer vacation, and most of the students had gone home, but the cafeteria was still open.

The reason is very simple, in this school that is already under great pressure, there will always be some volume kings like Chen Nianla, Wang Jiancheng, and Qiao Maila who stay in school.

However, today happened to be the time when Chen Nian and the other three made an appointment to have dinner together, so he didn't go to the cafeteria, but went directly to the hot pot restaurant outside the West Gate.

In the hot pot restaurant, Chen Nian saw the other three people who had already ordered the dishes and had been waiting for a long time.

"I'm just waiting for you, why is it so late today?"

Qiao Mai asked as he handed Chen Nian chopsticks.

"I'm sorry, I'm a little delayed."

Chen Nian didn't say it explicitly, and Qiao Mai didn't continue to ask.

She's actually not stupid in this regard.

Even if she hadn't joined Xinghuo like Li Xiang, she could guess that Chen Nian should have some confidential items in his hands that were inconvenient to talk about.

It's not surprising that she has such a project herself.

It's just that the scale is relatively small, and the role he plays in it is relatively marginal.

exchanged a few words of greetings, and several people started a hot pot in full swing, chatting about their recent events.

Li Xiang and Chen Nian knew each other well, and they covered very well.

Wang Jiancheng was tossing his exoskeleton, and now that he had more funds in his hand, he was also playful, and even began to wonder whether to get a large-capacity battery first

Qiao Mai, on the other hand, is relatively much more ordinary, attending classes, doing projects, and preparing to review for graduate school entrance examinations.

It can be regarded as the basic path of an "ordinary scholar".

After chatting for a long time, the pot was hot and the dishes were cooked, but several people were not in a hurry to move the chopsticks.

Not because the conversation was too engrossive, but because everyone was caught by a breaking news item on TV.

"On August 19, a major engineering accident occurred in a place in Hubei, and an auxiliary tunnel of a railway section collapsed during construction, causing 11 people to be trapped and have not been rescued yet."

"Fortunately, the tunnel ventilation duct was not blocked, and the 12 trapped workers were able to get the oxygen necessary for their lives, and the trapped 12 workers were unharmed."

"At present, the rescue work is actively being carried out"

Looking at the news report, the expressions of the four of them became solemn in unison.

"Shiyan. The geological conditions of that place are not bad, and the tunnel collapsed? It's an engineering problem, right? ”

Wang Jiancheng asked suspiciously.

"Not necessarily, it could be an engineering design problem, or it could be force majeure."

"In Hubei, in general, although it is not as complex and dangerous as the karst landform in the south, the underground water system is abundant, the rock erosion is serious, and the construction is still very difficult."

"In addition, the equipment we are building now is relatively backward, and it is normal for problems to occur."

"-—— can't say it's normal, in short, it's not unlikely."

After Qiao Mai finished speaking, he continued to sigh:

"In the past two years, the breakthrough in our military industry is indeed not small, but in the civilian field, especially in the field of civilian large machinery, it is really not enough."

"Look, we're working on high-speed rail now, but in fact, even if it's done, what can we do?"

"It's not okay to have a car without a road, no matter how fast the EMU is, it has to run on the railway."

"The terrain of our country is so complex, if we want to make high-speed rail cover the most places where it is needed, we have to build bridges and roads."

"Bridge erecting machine, shield machine, these are all areas where we are extremely backward."

"Extremely backward?!"

Chen Nian was shocked.

In his impression, these two things are typical cases of reverse export of domestic heavy machinery, not to mention domestic, and even in the era when he wore it back, the shield machine was beaten so that Western manufacturers had no food to eat.

With this kind of strength, there is still a time when "extremely backward"?

Looking at Chen Nian's incredulous expression, Qiao Mai nodded slightly and replied:

"yes, what else do you think?"

"I was originally engaged in machinery, I am more concerned about this piece, the last time I saw the report, now more than 80% of the domestic shield machine are dependent on imports."

"And, according to market forecasts, this number will continue to rise in the next few years, possibly peaking in '09, which is more than 98%."

"If that's the case, it's really hard for us to turn the tables around."

Good guys, 98%

In essence, the entire country's shield machine market is controlled by others.

Chen Nian couldn't help frowning.

According to historical experience, he knew that such a situation was temporary.

Just as the dilemma of rare earths being controlled by the West is also temporary, there are always ways to mobilize various resources at the top to fight a turnaround battle in these key areas.

But it is undeniable that this is a "turnover" after all.

It is to turn over, which means that we have indeed been pressed underneath, and we have indeed lost significant interests because of the suppression of the other party

If such a loss can be saved, how much will it be?

Chen Nian opened his mouth and asked:

"How much is the scale of our shield machine now?"

Qiao Mai shook his head and replied:

"I don't know the scale of use, but according to the forecast, by next year, we will have at least 200 units in demand."

"If you still want to consider the high-speed rail project, it is estimated that 300 units will not be able to stop."

"At the current average import price, a shield machine also needs at least 100 million yuan, so it is about 30 billion yuan in sales every year."

30 billion!

This doesn't seem like a big number, but Chen Nian knows that this number is a conservative speculation based on the existing situation.

After all, neither Qiao Mai nor those economists could have predicted the real speed of development of China in the future.

Around 2008, due to the knock-on effects of the Olympic Games and other factors, a large number of developed cities began to build subways, high-speed railways were fully rolled out, and some expressways and undersea tunnel projects were launched, and the demand for this thing was definitely not just 300 units.

He remembers a statistic that in 2020, the demand for domestic shield machines was 650 units.

Moreover, this number has decreased.

In fact, since 2011, the demand for shield machines has always been high, and in 10 years, the output digested internally alone should be more than 5,000 yuan

"That's a lot of money."

Chen Nian couldn't help but sigh.

"yes, this stuff is expensive. Hey, built, don't you want to make a mechanical exoskeleton? This shield machine is a large mechanical exoskeleton, why don't you just do this? ”

Wang Jiancheng rolled his eyes and replied:

"It's not the same thing at all, okay?"

"If you really want to build a shield machine, it's better to let the people who built the Sky Whale do it."

"The design of the cutter group of the Sky Whale is actually very related to the shield machine, and it is estimated that there will not be too much generation gap in technology."

"In addition, didn't it be advertised that the Sky Whale used the ship's integrated power system? It's the same with transplanting it directly to the EPBM. ”

Hearing this, Chen Nian's eyes lit up.

That's right!

The design of the Sky Whale is really similar to the design of the large shield machine.

No, it should not be said that they are similar, it should be said that the basic technologies involved in them are actually interoperable.

In this case, if you want to build a shield machine, it shouldn't be too difficult, right?

Thinking of this, he immediately clicked on the system page in his mind.

He then entered an analytic entry into the system.

"Zhenxing super large shield machine."

The results were quickly fed back into the system.

【Zhenxing Super Large Shield】

[Analysis requirements: 4 source points]

Really!

Chen Nian's spirits were greatly lifted.

It's cheap.

4 source points, compared to the 16 source points at hand, it's really sprinkling water-

However, of course, Chen Nian would not be so impulsive to analyze it immediately.

He must be responsible for the entire Spark team, for the entire country.

The regular meeting of the Spark team is tomorrow, and at tomorrow's meeting, he can put forward his own suggestions, and then let other more professional people judge whether it is feasible.

Thinking of this, he picked up his chopsticks again and put a piece of mutton in his bowl.

The others also came to their senses, and their eyes moved from the TV to the pot.

"I hope they're okay."

Li Xiang said with a sigh.

"It's going to be fine."

Chen Nian replied without thinking.

He just remembered that the accident was actually quite famous in his time.

This is a successful rescue under extreme conditions, and it can be regarded as a rare advanced case among the world's mine and tunnel rescue cases.

Relying on the experience of this rescue, in fact, in many subsequent accidents, we have done better than other countries.

However, even so, Chen Nian still had an expectation in his heart:

I hope that in the future, such accidents will never happen again
