"Whew!"

Huang Haojie endured the pain and covered Guo Ting, who was pregnant with Liujia, with a quilt.

Then go to the balcony alone to blow the wind.

Apparently he had received fragments of memories from alternate time and space again.

This time, the memory fragment is no longer the previous two parallel time and space, but a new parallel time and space, in the new parallel time and space, "he" is an ordinary maintenance worker.

Of course, it is ordinary, but it is indeed relative.

Because this parallel space-time has entered the interstellar age, humanity is already scourging the entire solar system.

And "he" is a small spaceship maintenance worker, and in parallel time and space, spaceship maintenance workers are just as hard as today's car maintenance workers.

But this identity is very useful for me now.

After all, the garbage of the interstellar era may be a treasure in the Blue Star era, and the difference in the times has caused the relative value of the same item or technology to be different.

Just like today's ordinary steel products, it was rare steel in ancient times.

So even though he is a maintenance worker in this alternate plane, "his" memory fragments are still very valuable.

Huang Haojie pressed his temples to relieve his headache, and then sat on the rocking chair on the balcony, sorting out the memory fragments in his mind.

In the previous two parallel time and space, due to the invasion of alien viruses in the virus era, the technology tree was crooked, and it seemed that it was still tossing in the blue star; The Age of the God Emperor has just entered the interstellar era, and this is still due to the reverse engineering of that alien spaceship of unknown origin.

The controllable nuclear fusion furnace that Huang Haojie has always wanted to obtain, but there have been no important memory fragments, and even the related memory fragments of quantum chips are becoming fewer and fewer, and now the integrity of quantum chips is less than about 52.7%.

Although Huang Haojie is using Zhong's artificial intelligence to promote quantum chips, many key technologies always seem a little plausible due to incompleteness.

So now the quantum chip is stuck.

After sorting out the memory fragments of parallel time and space just now, he was a little disappointed with the memory fragments this time, and most of the memory fragments this time were the content of daily life and how to repair the spaceship.

The only gain is a welding technique, which is indeed very powerful, but this thing is a piece of chicken ribs for him now.

However, it is better to have a harvest than nothing, and after sorting out the technology, he quickly uploaded the information of this welding technology to the internal server through the brain control system.

For the appearance of the third parallel space-time this time, it further shows that there are far more than two parallel space-times that he can receive, which makes Huang Haojie's previous worries a little less.

After all, the technology of the Virus Era and the God Emperor Era did not surpass the modern era much, and one day, when the technology of the main plane was on par with these two parallel time and space, that would be the time when he was exhausted.

Now that a new parallel time and space has appeared, Huang Haojie's worries have been reduced.

Seeing that the time was almost five o'clock in the morning, Huang Haojie had no intention of continuing to sleep.

He continued to lie in the rocking chair, his eyes closed, flipping through the memory fragments of the new parallel time and space in his mind, although the scattered memory fragments could not reflect the complete world view, but some of them could still be understood more or less.

Whether it is the memory of daily life or the memory of repairing the spaceship, Huang Haojie carefully read it.

In the 67th year of the Blue Star Calendar (2097), a generation of scientific giants?? Single by strength?? Lu finally came to the end of his life......

In other words, this guy has completed controlled nuclear fusion, ion engines, anti-gravity, artificial intelligence, ......

Looking at the memories of "himself" in parallel time and space, Huang Haojie had to wonder if this guy was hanging, a traverser? Or what system was obtained?

But regardless of whether this land force king is hung up or not, anyway, this parallel space-time has controlled nuclear fusion, ion engines and anti-gravity.

I hope that I will learn a little more knowledge in parallel time and space, since I am a spaceship maintenance worker, then the nuclear fusion core, ion engine, and anti-gravity equipment will be more or less in contact.

Parallel time and space, you have to be a little stronger! As a maintenance worker who loves to learn, I support you spiritually, and I can only support you spiritually.

After turning over for more than two hours, he was shocked by the legendary King Lu Qi, this product is definitely open.

"Brother Jie, why are you sleeping on the balcony?"

"Eh, I want something, Xiaoting, sit down, I'll tell the kitchen."

Huang Haojie, who was awakened, didn't continue to think, so he went to the kitchen to make breakfast.

……

Galaxy Technology Vacuum Pipeline Research Institute.

Chen Wenfeng, who has recently been troubled by the problem of vacuum pipe sealing, is taking advantage of the breakfast to flip through the internal technical journals of Galaxy Technology on the holographic display, hoping to touch the bypass.

After taking a sip of soy milk, he flipped through the academic papers with his fingers.

This time, the sealing problem of the vacuum pipe they encountered was not a problem with the sealing of the vacuum pipe itself, but a problem with the joint.

The vacuum pipe is made of graphene film composite fiberglass, and the longest section of this pipeline is about 50 meters.

In other words, in order to lay long-distance vacuum pipes, it is necessary to splice the vacuum pipes made in advance one by one.

The problem arises here, even if they use thick sealing materials for sealing, because they are not integrated with the pipe, there are often sealing holes, resulting in vacuum failure.

The problem is very serious, although the piers of the Strait Bridge have now been completed, and even the road bridge above is about 68% complete.

However, the vacuum pipeline has only laid 17 kilometers of single line for the time being, and you must know that the length of the entire strait bridge is 135 kilometers, and it is 3 double lines.

The sealing problem of the joint of the vacuum pipeline has seriously affected the progress of the project, which has to make Chen Wenfeng, the head of the vacuum pipeline research institute, anxious.

Ma Sixing, who was on his side, was also eating steamed buns while thinking about the solution.

Ma Sixing, who was racking his brains, looked at Chen Wenfeng, who was flipping through papers, and asked, "Wenfeng, are there any valuable papers that can be referenced?"

Chen Wenfeng shook his head: "No, there are some that seem to be referenced, but those are all theoretical concepts or laboratory level, and what we ask for can be put into use." ”

"Indeed, I have a solution that is not a solution." Ma Sixing said suddenly.

"What's the solution?" Chen Wenfeng asked with interest.

"That's what I thought, let's make another pipe, the inner diameter of this pipe is only a little larger than the outer diameter of the previous pipe, and then through the method of thermal expansion and cold contraction, this pipe is sleeved on the joint." Ma Sixing explained.

Chen Wenfeng touched his chin and thought about the feasibility of this plan, and soon he thought of a question:

"This may lead to overweight pipes, which will affect the stability of the bridge, after all, the bridge piers have been beaten first, and they can't be reinforced now!"

"I calculated that the weight would increase by 30~32% at most, and this weight is still within the redundant bearing range of the bridge." Ma Sixing hurriedly added.

Chen Wenfeng still shook his head:

"This option can only be used as a backup, not as a last resort, because it could shorten the life of the bridge."
