Siheyuan: I Have A Mysterious Factory

Even if the satellite launch is successful.

Everyone's research has not stopped.

It's just that now everyone doesn't need to fight like before.

Xu Dajun was not idle.

While it was late at night.

He opened the system listing again.

"System, exchange for RD-120 liquid rocket engine." Xu Dajun said.

[Ding: Congratulations to the host, the exchange was successful, and the RD-120 engine was obtained, and 800,000 technology points were deducted. 】

After the exchange was over, Xu Dajun was ecstatic in his heart.

The RD-120 liquid rocket engine can be said to be a legend.

It was not until 1990 that there was a more advanced RD-170 series than him.

Of course, for Xu Dajun.

RD-120 is enough for now.

At least, it is enough to make an intercontinental missile with a range of 14,000 kilometers.

Subsequently, Xu Dajun entered the system factory.

Looking at the engine in front of him, he couldn't help showing excitement.

If only he could figure out the engine.

It will be able to push the domestic aerospace industry to its peak.

After all, in the twenty-first century our country landed on the moon and explored Mars.

The rocket engines used are only the Y-100 series.

It can also be seen from here how exaggerated this engine is.

Xu Dajun took a deep breath to calm himself down.

The RD-120 liquid rocket engine has a diameter of four meters and a length of more than ten meters.

It's definitely a monster.

It is definitely the crystallization of the highest mechanical technology.

Looking at it, Dajun couldn't bear to dismantle it.

This is definitely one of the greatest inventions in the history of human mechanical technology.

"System, disassemble!" Xu Dajun finally gave the order.

After all, he exchanged this engine for research.

Don't look, this engine is almost the most advanced invention in the history of human development.

In front of the system, there is still no resistance.

In just a few minutes, the entire engine was disassembled into countless parts.

These parts are neatly placed on the ground.

Xu Dajun went up to check and stroked them.

There is still a little excitement in my heart.

Perhaps, such a masterpiece can be produced.

It's every man's dream.

Taking a deep breath again, Xu Dajun adjusted his mood and devoted himself to the research.

With the understanding of the previous liquid rocket engine.

Xu Dajun quickly figured out the principle of RD-120.

Then, detailed research began.

Measure each part and draw the most detailed drawings.

Finally, there is no need to disassemble and assemble.

In one night, sometimes it can be disassembled three or four hundred times.

Even so, Xu Dajun decided to do it after half a month of research.

It is estimated that at this time [Big Brother] did not develop the RD-120.

Sorry, we're getting there first.

the next day.

Xu Dajun, who was idle some time ago, suddenly became busy.

"Academician Song, can we change the fuel to kerosene?" Xu Dajun asked.

To ask why kerosene is used.

Because kerosene is convenient to store.

With the same volume of kerosene and dimethylhydrazine, kerosene is obviously more advantageous.

Longer battery life and greater thrust.

A certain superpower also eliminated the model of liquid oxygen and dimethylhydrazine later, and replaced it with the model of liquid oxygen and liquid hydrogen.

It can be seen from here that dimethylhydrazine is the most fuel and has obvious deficiencies.

Later, the intercontinental missile Dongfeng_5, which we developed with a range of 14,000 to 5,000 kilometers, was also changed to kerosene mode.

Finally, it has such a long range.

Of course, Xu Dajun said this to make his transformation to RD-120 appear more natural.

Academician Song hesitated after hearing Xu Dajun's words.

However, there is really nothing to do on my side now.

If you are idle, why not do as Xu Dajun asked.

After all, Xu Dajun brought everyone together to improve such a good engine.

"If you think so, let's try it." Academician Song agreed.

When other people around heard that Xu Dajun had a new idea, they couldn't help feeling refreshed.

"Academician Xu, how do you want to change it? You can say whatever you want, and we are willing to listen to you." Everyone said.

Xu Dajun looked at them and smiled with satisfaction.

"Then act quickly." Xu Dajun said with a smile.

Another aerospace revolution kicked off.

Hua_Xia has its own satellite?

The whole world is in turmoil.

When Sam heard the news.

The whole person is stupid.

"What did you say? China_Xia has its own satellite? Did Maoxiong launch it for them?" Sam looked at the assistant.

The assistant saw Sam's appearance and knew that he was on the verge of going berserk.

"It was developed by them independently. Among them, Xu Dajun completed the most core part, which allowed them to have their own satellite in advance." The assistant said cautiously.

Sam froze again.

Immediately afterwards, he yelled.

"What? Damn Huaxia people, damn Xu Dajun! Why are you always against me?" Sam started smashing again.

The new water cup, phone, and documents that had just been placed on the desk were dropped heavily on the ground by him.

Looking at this scene, the assistant felt a little used to it, and was no longer as scared as before.

Sam didn't calm down until the office was smashed again.

"Contact me General Ross." Sam gritted his teeth and said.

Neither satellites nor trade can pose a threat to China_Xia.

Then he can only use his trump card.

Soon, General Ross answered the phone.

"General Ross, give me a fleet." Sam said 017 calmly.

Seeing Sam's appearance, the assistant not only gasped.

Because, he knows.

Only when Sam really wanted to kill, the group would have such an expression.

There are two times.

For the first time, Sam was out to eliminate his country's competitors.

The second time, it was his wife's lover.

Those two people evaporated directly from this world.

Since then, no one has seen them again.

Now, Sam has such an expression on his face.

He also asked General Ross for the fleet.

What is this for?

An idea appeared in the assistant's mind, and he was not only taken aback.

"What are you going to do?" General Ross asked.

"You don't have to worry about these, I'll give you a billion dollars." Sam set out his own conditions.

After hearing Sam's conditions, General Ross had already guessed his purpose.

"I want five billion!" General Ross said.

Sam frowned slightly.

"Okay, I'll give you five billion, but this fleet needs to take everything." Sam continued.

"It's impossible. I only have the right to lend you warships and conventional weapons." General Ross also knew the bottom line.

Sam considered it.

"good!"

For myself, in fact, having a fleet is enough.

He looked to face his own fleet.

China without a navy.

What will be the reaction!
