Did the world end today?

Chapter 65 Resurrection from the dead?
Engine, fuel, flight control, fly-by-wire, communication, detection, life support
Lin Xu listed all the major technological categories required for a spaceship.

He then discovered that, with current technology, assembling a spaceship didn't seem that difficult.

However, building a spacecraft that can fly stably in space for more than six months and land successfully on Mars is actually not that simple.

All systems are interconnected, and even a single weak link can cause the entire system to collapse.

In a word.

Flying up isn't a skill; landing alive and returning alive is true success.

This is not a good thing to do.

Lin Xu roughly summarized the technical difficulties he understood and compiled them into a document.

He then made a direct phone call to Chu Xu, the chief engineer of Tianqiong Technology, inviting him to his office for a "discussion".

After witnessing the "power" behind Lin Xu, Chu Xu also placed high hopes on this young man.

He didn't waste a few minutes before putting down his work and rushing over.

After a few brief pleasantries, Lin Xu immediately presented the document in his hand.

After reading it, Chu Xu frowned slightly and asked:

"Comrade Lin, are you trying to turn the Star Travel No. 1 project into a completely self-developed and self-produced project?"

"Self-developed and self-produced?"

Lin Xu was stunned for a moment.

"That's not it."

"But from my current perspective, this project does indeed face many technical challenges."

"And for the time being, we cannot obtain many of these technologies from the open market."

"Therefore, instead of wasting time negotiating and seeking technology transfer, it's faster for us to develop it ourselves."

As soon as he finished speaking, a bitter expression appeared on Chu Xu's face.

Is self-development faster?
What are you talking about!

If self-developed technology were truly fast, wouldn't other competitors have already taken off?

Why is Sky Dome Technology still flying test ships and making 1:20 scale verification models on the ground?

Isn't it because the technology didn't meet the standards?
If you're talking about launching a rocket or sending a satellite into space, then anyone can do that.

But what you're trying to build now is a real spaceship.
Wait a minute.

You make it sound so simple, it's not because you already have connections, is it?

The more Chu Xu looked at Lin Xu's face, the more he felt something was wrong.

That expression doesn't suggest they're trying to negotiate with me.

It seems they intend to use their own hands to issue a "notification".
Understood.

Chu Xu coughed and said:
"Then I understand."

? ?
What do you unserstand?

Lin Xu was baffled, but Chu Xu continued speaking.

"Actually, our biggest problem right now is still the engine."

"The rocket engines we use now are quite outdated - in fact, even the propulsion systems used by other top companies in the world are not very advanced."

"Therefore, the best way to solve this technical challenge is..."

"Actually, we are still following the official line."

"We'll go in the same direction they go."

"Feeling your way across the river by touching the stones is also a shortcut."

"understood."

Lin Xu nodded slowly.

"What is the most advanced rocket technology right now? What are the current challenges?"

Lin Xu’s words were clearly a question, but to Chu Xu, they sounded like a rhetorical question.

"Two aspects."

"The biggest problem is, of course, the instability of combustion. Pressure fluctuations in the combustion chamber can lead to explosive oscillations."

"The current solution to this problem is generally to use injectors, such as coaxial or centrifugal injectors for precise control."

"However, there are limits to simply following the injector route. Improving the inherent strength of the combustion chamber is also very important." "This is actually a materials science problem."

Chu Xu paused at this point.

After confirming that Lin Xu had no further questions, he continued:

"The second problem is the deep thrust adjustment problem, which is very complex and involves a great many technical categories."

"Combustion chamber, turbo pump, sensors, ECU, closed-loop feedback."

"We've actually made pretty fast progress in this area. Our YF-75D can already achieve 50% to 100% thrust control through a gas generator and flow control."

"However, there is still room for further improvement."

"The main direction is to optimize the engine cycle."

"We are currently using a gas generator solution, and further improvements can be made towards full-flow staged combustion."

"However, this improvement is not so simple."

"I understand, this is a systematic project."

Lin Xu nodded slowly.

It's very difficult.
-
If all you can get in the bracelet world is technical support from Sky Dome Technology, then that's incredibly difficult.

But now, he has successfully established contact with Bai Mo.

Perhaps it wouldn't be so difficult to get what I need through her?

He unconsciously revealed a confident expression, and Chu Xu understood immediately upon seeing his reaction.

Okay, that's confirmed.

But that's strange.

If such technology truly exists, why doesn't the government use it first?

Or is there another reason behind this?

That's not something I should be thinking about.

I won't ask, I won't listen.

Just do your own thing!

Lin Xu pressed Chu Xu for a few more specific questions before seeing him off from the office.

The direction is basically clear now.

The next step is to go to Bai Mo for the technology.

I don't know if the password we agreed on last time will still be effective.

If I don't need to meet her in person and can contact her remotely, I can save a lot of time.
One hour is still too short.

If only we could extend our survival time after the apocalypse.

But based on my own experience of dozens of times, this is simply impossible.

Even if you find an underground bunker to hide in, you can't escape that kind of "unknown killing power".

The white light is merely an external manifestation of the impending apocalypse; the way it kills humanity remains completely unknown.

No one can survive, and no one can come back from the dead.
and many more.

Lin Xu suddenly froze.

Resurrection from the dead.

It's not that it's impossible to do.

Bai Mo himself said that some people in the Planetary Reincarnation Organization who have entered higher dimensions are able to perform the miracle of "resurrection"!
Is that possible?
Can I do that myself?
Just do it within the world of fitness trackers!

That's right. Even if everyone else dies, even if the world is destroyed, as long as you can come back to life, you might be able to get one step closer to the truth!
How to do?
Lin Xu took a deep breath.

He picked up his phone and found Bai Mo's number.

I dialed the number, and a moment later, the call was connected.

Lin Xu began to speak:
Have you come to the company yet?

"Come to my office."

"I have something to talk to you about!"
