The blocks officially began operations on July 10, 9995 BC in BC10000-1.

The power plant is operational, and the 400-kilometre network has been officially launched.

All the materials here do not need to be consumed, except that they are not wasted, and everything is taken and used consciously.

To a certain extent, these 1,000 blocks constitute a real dream town.

Presently......

The 1,000 blocks were divided into 50 project groups.

Every twenty blocks become a group.

Each group includes nuclear physics, materials science, plasma physics, superconducting magnets, ultracooling deflectors, and tritium preparation plants...... and so on.

The researchers in each block are the top personnel in the relevant industries of the Dragon Kingdom.

And these people are almost wasteful, and in each block, they do not exert all their light and heat.

They will make breakthroughs in tackling key problems day after day in the future.

Once a project team achieves a breakthrough, this breakthrough will be quickly transmitted to the other 49 project teams through the network, so that everyone's progress is consistent.

But even so, it is difficult to make a real breakthrough in controlled nuclear fusion.

At present, mankind has invested a lot of money and time in the direction of controlled nuclear fusion.

Even mankind has mastered the principle of controlled nuclear fusion, and has long achieved the use of uncontrollable nuclear fusion through hydrogen bombs.

It is a nuclear fusion reaction induced by using a nuclear bomb as a fuse, and the high temperature in the center of the nuclear explosion is used to induce nuclear fusion, resulting in a more violent and ferocious explosion.

Ranwen

And this just shows why controlled nuclear fusion has been known for a long time, but it has not really been achieved decades later.

It is precisely because the conditions for controlled nuclear fusion are too harsh.

However, despite the harsh conditions, the prospects for nuclear fusion are too bright......

So much so that even if the difficulty is extremely high and the investment is huge, it is still flocking.

Moreover, thermonuclear fusion reactors currently exist internationally.

Because the whole world understands that once controlled nuclear fusion is truly successful......

Human beings will be completely liberated from energy anxiety!

It will say goodbye to the ancient and huge pollution of fossil energy, so as to completely reach the point of "unlimited energy"!

……

……

At this time, the end of the timeline is November 15, 2023, at 23:00 PM.

20231111-1 Parallel Timeline Time, July 10, BC9995, 6 p.m.

Lu Yun glanced at his timer.

[Life Remaining: 867:32:51].

[Mission Time Remaining: 736:32:51].

From the time he and Pan Lishan landed from the temporary airport in the Northeast Plains to the present, only five hours have passed on him.

But in this parallel timeline, nearly five years have passed.

At this time, Lu Yun took his eyes off the timer and looked at the conference hall of the first block.

There were about 200 people seated in the chamber.

After the first lunch in the cafeteria, the people who had just settled in the base first chose their favorite accommodation, put down their luggage, and the heads of various specialties and the main executives came to this conference hall.

The meeting has been going on for a while, and Lu Yun is specially here to listen to the final summary.

According to what I have learned before......

At present, there are two ways to divide the nuclear fusion pathways of countries around the world into fusion materials.

The first is to collide with the deuterium element, D-D polymerization, so as to achieve the release of energy.

The second way is to take out and collide with deuterium and tritium, and D-T is polymerized to release energy.

In terms of fusion methods, there are also two methods.

One is a strong magnetic field that binds charged particles.

The other is excitation with a high-intensity laser.

It seems that permutations and combinations can have different experimental directions.

But all 50 experimental groups chose the same option.

That is the D-T reactor bound by a strong magnetic field.

As for the reason, it is also very simple.

The nuclear fusion reactor on the flying saucer, a mature technology, uses the D-T reaction under a strong magnetic field.

Through the reverse development of the fusion reactor on that flying saucer, it will be the fastest and most reliable way to achieve the use of controlled nuclear fusion in the finished product.

And in order for the deuterium and tritium elements to collide, two points are needed.

High temperature, increase the movement rate of deuterium and tritium.

High pressure to increase the density of deuterium and tritium.

It is extremely difficult to meet the requirements for stable and controllable nuclear fusion.

It needs to be held for a thousand seconds at a temperature of 100 million degrees.

Commonly known as "ignition".

In order for nuclear fusion to achieve that the input energy is less than the output energy, the first thing to do is this ignition work.

There are a number of challenges that need to be addressed.

To complete the ignition, the helium atoms produced by the D-D collision bound by the strong magnetic field will affect the internal reaction.

At the same time, the uncharged neutrons "scattered" by the collision of elements will also cause damage to the reactor wall.

Coupled with the requirements of high temperature and high pressure......

All of these are the difficulties that need to be overcome to achieve controlled nuclear fusion.

At this time, Sun Chengfeng, a nuclear physicist who spoke at the meeting, was making his final concluding remarks:

"Since our project is D-T's strong magnetic field heating ignition scheme......"

"Then the first thing to solve is the material solution."

"I think a reverse study from the fusion core of that flying saucer will allow us to make rapid progress on this point."

"The equipment is ready, we just came here today, let's get familiar with the working environment as soon as possible, and start the experiment tomorrow."

"Our first goal was to replicate the strong magnetic field of the template reactor."

"Disband."

In this originally quiet conference room, after hearing the word "disband", a loud noise rang out in the large conference hall.

And Lu Yun also stood up at the same time.

However, he didn't find anyone to ask anything, after all, no matter how many questions he asked, there was no one who could be more professional than these professionals.

Lu Yun quickly stepped into the gate of time and space.

In plain sight, disappeared.

……

……

After Lu Yun understood the basic situation, he spanned thirty years on this parallel timeline in one step.

July 10, BC9965.

He directly found Pan Lishan in Block 1.

But when Lu Yun saw Pan Lishan's familiar face......

His eyes changed imperceptibly.

Pan Lishan in front of him is completely no longer in spirit.

He looked extremely tired and old.

Also......

Now he is eighty-two years old.

"Ahem, ahem."

Pan Lishan coughed a few times, looked at Lu Yun and said:

"You...... You're finally here. ”

Lu Yun forcibly suppressed the strange feeling in his heart, and asked:

"How's it going?"

Pan Lishan took a few deep breaths, and it seemed that speaking was already a torment for him.

After a long pause, he spoke hoarsely:

"It's not very good."

"We're stuck in a bottleneck in reverse R&D."

"We can't reproduce the material that binds the strong magnetic field."

"The high-temperature and high-pressure environment cannot be maintained for more than 700 seconds."

"The whole project team was stopped here."

Lu Yun nodded, this is also an understandable thing.

After all, it is necessary to break through in a certain direction first by refreshing the timeline.

You must know that in 2023, the nuclear fusion ignition experiment of mankind can only be carried out for more than 100 seconds.

In thirty years, breaking through seven hundred seconds is already a great feat.

At this point, he spoke again and asked:

"What about Sun Chengfeng?"

"I'm going to get some papers."

Pan Lishan was silent for a moment, and then spoke:

"Died last year."

"Heart disease, can't be saved."

Hearing this, Lu Yun's Tong Kong shrank suddenly.

He did anticipate that in the span of thirty years, something sad would happen.

But when he heard the news, he still felt that his heart was not happy.

However, when Pan Lishan saw Lu Yun's expression, he smiled and said:

"Don't say it, Old Man Sun does have something to bring to you."

"We've made great strides in materials, magnetic fields and superconductivity."

"The past 30 years have not been in vain."

As he said this, Pan Lishan stuffed a hard drive into Lu Yun's hand.

This hard disk should contain all the achievements of each project team in the past 30 years.

And Pan Lishan looked at Lu Yun with a smile, his eyes were obviously cloudy, but they were flashing with light.

Pan Lishan opened his mouth and said:

"I hope that Old Man Sun can see the success of controlled nuclear fusion before he dies."

"If only we could live longer."

Lu Yun felt a little surprised:

"Isn't 'Nine Sets' useless?"

Professor Sun ...... last year Ninety years old, right? ”

"It shouldn't be......"

"Our medical conditions ......"

Pan Lishan shook his head and said:

"The later you practice, the worse the results."

"The old grandson always forgets."

As he spoke, he changed the subject:

"Old Lu ......"

He said the title again, but he was stunned.

Since I met Lu Yun in 1995, the two were almost the same age at that time, but now it seems that they are so old.

He smiled helplessly, and then said, "It was Sun Chengfeng's apprentice Qin Lijuan who took over the baton." ”

"You can ask her for the specific situation."

"She should be eating in the cafeteria right now."

Lu Yun nodded, grabbed the hard drive, and stepped into the cafeteria of Block 1.

The number of people in the cafeteria is quite large.

But it looks ...... It's already like a nursing home.

There were no young people at all, and the youngest looked like he was almost sixty years old.

These people, who were eating silently in the cafeteria, saw Lu Yun's appearance, and their eyes looked very surprised.

And the surprise in those eyes immediately turned into envy.

In the midst of envy, there were some other emotions, but Lu Yun didn't care about them.

His eyes quickly locked on Qin Lijuan's name on the screen in the crowd.

However, when he finally got the man on the spot......

But I was a little surprised.

This Qin Lijuan...... It was the woman who said she was going to give up on joining the program, giving up academic research, and wanted to go home and watch her son thrive.

“……”

Everything he once said in the Xiaoshan conference room is still vivid.

I didn't think anything at the time.

But now, I think it's a little strange.

But......

The timeline is refreshable.

Lu Yun didn't think much about this matter.

He came to Qin Lijuan's side and said:

"Professor Qin, take a step to speak."

Qin Lijuan saw that it was Lu Yun, and her face looked a little surprised.

And unexpected emotions immediately become extremely complicated......

But in the end, it just turned into a sigh.

She followed Lu Yun to a corner where no one was around, and just as she was about to speak, she was snatched away by Lu Yun.

"Is there anything you would like to say to you thirty years ago?"

Hearing this, Qin Lijuan's expression froze.

Then she snorted coldly:

"If there's anything, it's to tell myself thirty years ago, don't follow the team to this hellish place!"

At this time, Qin Lijuan swept the hard disk in Lu Yun's hand, took another deep breath, and then said:

"Thirty years ago, I would have told my teacher."

She seemed to be prepared and stuffed a note into Lu Yun's hand.

Then, she pointed to the hard disk in Lu Yun's hand and continued to speak:

"The breakthrough in materials science of the sixth project group has allowed all of our project teams to exceed 600 seconds."

"The 30th project team broke through 700 seconds last month."

"However, even if it is a thousand seconds at the moment, it doesn't make sense."

"If it is not possible to find a material that can maintain its strength at 100 million degrees Celsius, if there is no guarantee that the material will not cause problems under the high-speed impact of uncharged particles......"

"Even if the ignition experiment is completed, there is no way to turn this thing into a usable energy source in the end."

At this time, Qin Lijuan told Lu Yun everything she knew very seriously:

"If this material can't be developed, then everything is in vain."

"It's like a reverse study of alien spacecraft materials, there is no way to do it."

"That kind of intensity ......"

Qin Lijuan didn't find the right words to describe the material of the alien flying saucer.

But she was quick to add:

"Anyway, it's the material that's the most important thing."

"The technological content of this alien flying saucer is at least 300 to 500 years ahead of human beings."

"You should know what is the speed of human technology development now."

Lu Yun nodded.

But Qin Lijuan smiled after saying this, and said:

"I didn't expect this to be the reason for coming here for experiments."

"You're going to change the past here, aren't you?"

"Awesome."

Thirty years, combined with what she has learned, it is actually logical to deduce Lu Yun's methods.

At this time, Qin Lijuan sighed, and seemed to switch from a scholar to an ordinary woman.

At this moment, she seems to have awakened the soul of gossip:

"That is to say, the lithography machine and the pyramid, and the ascension of the first emperor...... You did it, right? ”

"What's the deal with that bride price?"

"We don't have the bride price problem in our senses, are you restarting history?"

She looked at Lu Yun, smiled and said:

"Am I right?"

"Lu Zhenren?"

Lu Yun was stunned when he heard this, feeling a little sudden.

At this time, Qin Lijuan explained:

"We haven't had any entertainment in the past 30 years, except for work."

"At first, everyone was shy about talking about you......"

"It's been a different story in the last decade."

“……”

"I didn't expect to be able to talk face-to-face with the author of "Under Heaven......"

When Lu Yun heard this, he also smiled helplessly.

I didn't expect to become the talk of these experts after dinner.

"Alright."

"Lu Zhenren."

"Go and change the future."

"We ......"

"I will continue to work hard as always."

Speaking of this, her face seemed to be a little dark:

"Take my teacher's share."

Lu Yun nodded solemnly.

He knew there was no point in saying anything.

Only by letting this end as soon as possible can they be freed from this prison life.

He was back in the morning of July 11, 9995 BC.

On the network, which had just been opened more than ten hours ago, Lu Yun uploaded all the documents in the name of the "Project Zero Team".

These documents make the dark night in the early hours of the morning no longer quiet.

More and more lights came on.

More and more people rolled over and got out of bed and rushed to the lab.

And this ......

It's a new beginning of reincarnation.
