Siheyuan: I Have A Mysterious Factory

world today.

Not many countries can launch rockets.

If we can have a stable launch rocket technology.

Then we will become the third country in the world to launch a rocket.

This represents more than just face, the most important thing is the proof of national strength.

We also have reasons why we must do it.

Satellites will become an indispensable thing in the future world.

First, there is nautical navigation.

Secondly, it is satellite positioning.

There are also global monitoring, satellite communication and so on, which have entered people's normal life

The role of satellites cannot be ignored.

It is precisely under such circumstances that the development of the aerospace industry should not be underestimated.

"Young people are so powerful, we can't slack off." Quan Guoshi said.

Quan Guoshi issued an order to everyone in the Fifth Research Institute to develop new rockets with all their strength.

Following this command, all the scientific researchers who studied rocket satellites all started to move.

Everyone knows that someone has created the most advanced liquid rocket motor.

Others can do it, why can't I?

So, everyone put in all their energy and worked desperately on research.

During the next period of time.

Good news came from each group, and difficulties were constantly overcome.

And during this time.

Xu Dajun and the others were not idle either.

With the help of his own system, he has been able to create the most perfect Y-20 series liquid rocket motor.

However, even so, there is no way to meet Xu Dajun's requirements.

It is definitely not a simple matter to break through the Y-20 series and upgrade the technology to the Y-75 and Y-100 series.

"System, can it be exchanged for Y-75 series liquid rocket engines?" Xu Dajun asked the system.

[Ding: The host does not have the right to exchange. 】

"What about the Y-100 series?" Xu Dajun didn't give up.

[Ding: The host does not have the right to exchange. 】

Xu Dajun was not only disappointed when he heard the system's answer.

However, he soon remembered something.

The technologies I mentioned were developed in China a long time later.

There are also more advanced liquid rocket engines in the same period as the Y-20 series abroad.

"What about RD-120?" Xu Dajun was a little excited.

The RD-120 is the prototype of the Y-100 series.

It's Big Brother's most advanced technology.

In the future, it will be obtained by us and reversed.

It took 20 years to develop our own Y-100.

If you can redeem the RD-120 series, it is equivalent to redeeming the Y-100 series.

【Ding: Do you want to exchange for RD-120 liquid rocket engine?】

"Can it be exchanged?" Xu Dajun couldn't help but jumped up excitedly.

In the future, China_Xia will have Y-75 and Y-100 after the Y-20 series.

However, the technology of these two series is juxtaposed.

The Y-75 series is our self-developed oxyhydrogen machine, which uses liquid hydrogen and oxygen as fuel.

The Y-100 series is a kerosene engine modified by us based on the RD-120.

These are also the two most important categories of future aerospace engines.

The technological content is comparable.

Moreover, the Y-1 series and Y-20 series also inherited the technology of Big Brother.

Now I continue to study the RD-120 series, which can be said to be passed down in one continuous line.

Thinking of this, Xu Dajun started to exchange without hesitation.

"System, exchange it for me."

[Ding: There are insufficient technology points and cannot be exchanged. 】

"This...uh..." Xu Dajun regretted his extravagance.

Then, he checked the exchange price of the RD-120 series.

[RD-120 liquid rocket engine needs 800,000 technology points]

Xu Dajun looked a little greedy.

Look at your remaining technology points.

[Remaining Technology Points: 153]

Seeing this, Xu Dajun felt like crying.

"I always thought that three million technology points were a lot, but not enough." Xu Dajun had a sad face.

Without technology points, you cannot redeem RD-120|series by yourself.

Then I can't continue my research.

Thinking of this, Xu Dajun actually relaxed.

In just one month, I have allowed Huaxia's liquid rocket engines to span decades.

To achieve this level is already very exaggerated.

It's just that I still don't feel enough in the Tianshi.

The phobia of technological backwardness has been baked into the bones of him, a future Chinese.

Fortunately, now my technology points are growing quite fast.

With the promotion of latch needle warp knitting machines and electric furnace steelmaking, he can get 20,000 to 30,000 technology points a day.

It seems that I can only wait now.

As Xu Dajun stopped, everyone in the project team had nothing to do.

A few days ago, Xu Dajun desperately modified the engine overnight.

As a result, Xu Dajun didn't do anything and didn't care about it these days.

This made everyone a little at a loss.

Academician Song looked at him worriedly.

"Academician Xu, what's wrong with you? Are you sick? Are you tired? If you want to rest, take a few days off." Academician Song said carefully.

Xu Dajun also knew that he was worried about his health.

"I'm fine, you are busy with you, don't worry about me." Xu Dajun said to him.

What are you so enthusiastic about?

It made me feel ashamed to be lazy.

After finishing speaking, Jin Dajun walked to the project team next door.

Academician Song was a little dumbfounded.

Not only Academician Song, Zhong Caijun and Zhu Yuejin were also dumbfounded.

I don't know what happened to Xu Dajun today.

"Since Academician Xu wants to take a break, let's take a break and let's do it ourselves." Zhong Caijun said to everyone.

But what to do next?

The people present were a little at a loss.

They seem to have gotten used to not thinking and just obeying Xu Dajun's orders.

If only they knew the results of their time.

It is already the best liquid rocket engine in Huaxia in the next few decades.

I don't know what it will feel like.

Academician Song also didn't know what to do.

"Let's move freely!" He said the most irresponsible words.

The people present were a little dumbfounded when they heard this.

Now, thousands of researchers in the Fifth Research Institute are working desperately.

And on my own side, "free activities"?

Everyone didn't know what to say immediately.

So, in this small courtyard, a strange scene appeared.

The other people in the two bombs and one satellite project are all very busy.

As a result, Academician Song and the others felt uncomfortable.

nothing to do?

Then move freely.

Free activities don't know what to do?

Then clean up.

The entire research room, 940, was cleaned spotlessly by them.

Xu Dajun didn't go there any more, and stayed next door for the past few days.

"Old Qiu, share your Dahongpao with me?" Xu Dajun and Qiu Zhenhua became one.

Qiu Qingzhi was a little embarrassed to understand Xu Dajun.

After all, every time you meet, you must bow and say hello to the teacher.

It was a real embarrassment for her.

But, Xu Dajun, a scoundrel, why is he stuck here and not leaving?

Is your project out of research?

Are you complacent after getting a second-class collective merit?

"Don't seek to make progress!" Qiu Qingzhi squeezed out this sentence from between her teeth.

After speaking, I immediately felt a lot better.

However, for her, if she wanted to say something worse, she couldn't open her mouth.

Qiu Zhenhua looked at Xu Dajun with helplessness.

Want to refuse, but hesitate, did not refuse.

"Xiao Xu, it's fine to give you some tea. Please help me look at this place, can you change it?" Qiu Zhenhua pointed to the blueprint and said.

During this period of contact, Qiu Zhenhua also knew the strength of Xu Dajun.

Therefore, he also knows what is called "make the best use of everything".

We must fully seize the opportunity and make good use of the treasure Xu Dajun.

For this reason, Comrade Lao Qiu has made plans to sacrifice his daughter.

Qiu Qingzhi, who was next to her, was complacent that she had found a way to vent.

"Stupid army, stupid stone, cheapskate, idler, slacker.

She whispered all the curse words she could think of, and said them in a low voice.

Gradually, a smile appeared on Qiu Qingzhi's face, and all the pressure disappeared.

But don't know.

Dear Comrade Lao Qiu is already thinking about how to send her to the stupid army of "stupid stones". .
