Longing: I just made a battle armor, my sister asked me for help

At this moment, in the underground base.

Jiang Chen's face was flushed red with excitement.

Zifeng's words woke him up.

It also made him clearly aware of the relationship between home and country.

So now make your own choice.

With a thought, the system interface appeared.

Now the accumulated points have reached a staggering 510 million.

And the growth rate is still very fast.

Much faster than normal breathing growth.

Accumulated points can be exchanged for rewards.

As long as there are things in the mall, they can be exchanged.

Famous watches, sports cars and mansions!

Even shares in top companies!

All can be exchanged!
Even the world's top technology can be exchanged!
As long as the value is high enough.

Even in the next century, the technology of the next century can be obtained directly!
There are many material rewards in front of you.

A few hundred points can be exchanged for a luxury car, and a few thousand points can be exchanged for a luxury house.

Even if it is the shares of the world's top 1, it is only more than [-] points.

But Jiang Chen was unmoved, what he wanted in exchange was not these.

Keep sliding back.

The interface is changed again.

Many technologies have appeared, and the accumulated value of each requirement is extremely exaggerated.

Often 10,000+ millions.

Even some exaggerated technologies are as high as tens of millions.

The interface in front of me is constantly changing.

Stop now!
Robotic arm technology: 600, 0 points! (redeemed)

Advanced Laser Cannon Technology: 18 (exchanged)

Anti-radar stealth technology: 23 (exchanged)

……

Nuclear power system technology: 300! (redeemed)
Ultra-era armor technology: 500! (redeemed)
These technologies in front of him are impressively what Jiang Chen applied before!

There are also many technologies created to help parents.

But these have all been redeemed.

With a swipe, the information in front of you changes.

And the following are technologies without exchange, each of which is very attractive.

Space shuttle technology: 23 points! (not exchanged)

Sky Carrier Technology: 38 points! (not exchanged)

Cold Fusion Technology: 45 points! (not exchanged)

Micro controllable nuclear reactor technology: 87 points! (not exchanged)

…………

Every single one out is absolute world-class technology.

It is also a top-level technology that completely crosses the era.

But although the technology is very powerful, the technical points required are relatively exaggerated.

This is already a technology with tens of millions of accumulated points, and there is no way to buy or exchange it with the current points.

If you want to exchange for this level of technology.

That requires even greater exposure and more attention.

Although there are 500 million in the account now, it is still not enough to see.

Also accumulate slowly.

Jiang Chen kept refreshing.

The interface in front of me is constantly changing, but all the technologies that appear are tens of millions and millions.

All are above 500 million.

Even during the period, several top black technologies with accumulated points of over [-] million appeared.

But those are not within the expected range.

What is needed now is a technology that has less than 500 million accumulation points and is also helpful to Daxia.

It was another search, and I don't know how many times it was.

But now, Jiang Chen raised his eyebrows when he saw the technology in front of him.

"what…"

"This thing?!"

What is in the picture now is the lithography machine technology!
This is exactly what is needed right now!

And it is urgently needed!

A photolithography machine is also called a mask aligner.

It is the key equipment for manufacturing micro-electromechanical, optoelectronic, and diode large-scale integrated circuits.

Maybe this is a little strange.

But the lithography machine directly decides another thing!
chip!
Basically, if you want to make chips, it is the core equipment!
But the technology of this thing is in the hands of Western countries such as the beautiful country.

Many aspects of Daxia's chip field are stuck.

It is also within the academic blockade and technology monopoly of the beautiful country.

It is really difficult to seek development.

At present, the true level of domestic lithography machines is the 180nm process.

In China, some top companies may have reached the 90nm process.

But the gap with foreign countries is still too big.

You know, now the top lithography machine can completely reach the 5nm process!

Even 3nm process technology is under study!
The gap in numbers is already huge, but in fact the gap in technology far exceeds the distance in numbers.

因为光刻机从90nm、65nm、45nm、28nm、14nm、7nm、3nm，每个等级都是一个技术台阶。

And each level of technology is a huge upgrade, or even a complete subversion of the previous technology.

Among them, from 65nm to 45nm is a huge gap, and it is very difficult to complete this leap.

And the level of research at home and abroad can be said to be very different!

The accuracy of the lithography machine affects the manufacture of chips.

Chips with different precision directly affect the performance of many high-precision equipment.

Let's take the simplest example, a mobile phone!
The higher the precision of the chip, the better the performance of the mobile phone.

Therefore, the actual implementation of science and technology affects the competition among enterprises.

It is the economic impact of the entire industry.

It can be said that the scientific researchers of Daxia have gone through untold hardships on this road.

Research in the field of lithography machines still has a long way to go.

call…

Jiang Chen let out a breath slowly, and focused his attention on the price.

500 million!
No more, no less!Just right!

Jiang Chen's heart trembled slightly, and he immediately made a decision.

"That's it!"

This is undoubtedly the most suitable exchange object at present!
Not only can it help Daxia break through the shackles, but it can also upgrade his armor technology.

If you want to upgrade artificial intelligence in the future, chip technology is also essential.

Make an exchange with a thought.

The accumulated value of 500 million points was instantly emptied.

At the same time, a large amount of information appeared in Jiang Chen's mind.

A lot of high-tech theoretical knowledge, as well as a lot of academic information.

It's all going on in his mind.

And Jiang Chen seemed to have become a sponge at this moment.

Absorb this vast amount of knowledge.

Now the research on lithography machines has grown from scratch and is becoming more and more profound.

And the level of comprehension is getting higher and higher.

A few minutes passed, and Jiang Chen already had a new understanding of this whole technology.

Even the technologies in many related fields have been dabbled in.

He is still absorbing knowledge continuously.

At the same time, the beautiful country released a message.

'The end of the month!Launched 5nm process lithography machine! '

As soon as the message is sent out!The whole world shook!

Everyone who saw this message was shocked from the bottom of their hearts.

And everyone knows that this technological competition has begun!
