"In the end, this mountain will still be razed to the ground, right?"

This kind of climbing in a low gravity environment is a bit different from the normal environment, and most of the physical strength is adjusting their balance.

Ji Lin Xuanxuan felt sweating on her forehead and quickly issued a series of instructions. The human-computer interaction technology is now quite developed, and the bionic hand in the glass helmet wiped off this little sweat very accurately.

"That may not necessarily... in the end it depends on the project planning." Zhang Yuan said: "If this place needs to be equipped with a curvature engine, the geographical appearance will still be destroyed."

It took about 12 hours to finally climb the 28,000-meter-high mountain.

After exercising for so long, even in a low gravity environment, even if you have a power armor, you are still very tired.

At this height, you can clearly see the distance of the horizon. A Dyson ball loomed in mid-air. It gradually bursts out its own bright light, completely illuminating the earth.

It took several hours before it slowly faded.

This wonderful periodic light change can spread throughout the Milky Way as time passes.

Zhang Yuan kept looking at the Dyson ball for a long time.

Human construction sites in the distance are busy. After adding new production lines, the development speed of engineers has increased significantly. However, ordinary people still cannot tell whether industrial production capacity is rising or falling with their naked eyes. Only internal staff can experience the convenience.

The planetary curvature engine looks like long lollipops, with a ball on top and a tall and long base tower on the bottom.

These base towers are a height of 64 kilometers in total, which is much taller than Mount Olympus!

They are all rigid body structures. Thanks to the small size of this planet, its gravity is only half that of the moon. In addition to the emergence of various super materials, human rigid body buildings can pile up so high. These materials are basically the limit of conventional materials.

At the top is a circular instrument, that is, a planetary curvature generator, which can work in a coordinated manner.

Basically, the planetary curvature engine structure of each level four civilization is roughly like this.

Such planetary curvature engines must be built at least 900 of them worldwide, so the project volume is quite large, and people need to work overtime day and night for 20 years of hard work.

Standing on the mountain and looking into the distance, watching the speed, the trains come and go, it feels like seeing the small mountains.

The nearest construction site was a group of soldiers installing purchased arms. Through long pipes, it can be seen that it is an ion cannon.

The performance of this thing is not very good, and it will not specifically build a deep defense foundation for it, which can be laid casually on the surface and can be used after it is connected to energy.

Among a mountaineer who was traveling with him, there happened to be a man in charge of this work. He said: "For such ion cannons, it is expected to be placed 200,000 units and 300,000 laser weapons. This can give Zhanxing some combat effectiveness... The amount of arms purchased is not enough, so we have to make some ourselves."

Zhang Yuan smiled bitterly and said, "I have no money. If I have money, we will definitely buy more."

"First solve the problem of whether there is any problem, and then find a way to solve the quality problem. Being combat-capable and not having combat-capable are two different concepts."

"Is the situation so serious?" Several other people were government workers. After hearing their discussion, they came over.

"Yes, I won't hide it from everyone this time, the situation may be quite serious. Even if we make mistakes in predictions, it's good to plan ahead."

Lin Xuanxuan suddenly asked, "The 500,000 turret firepower is not enough?"

Zhang Yuan explained: "Of course not enough! You have to think about it, this is a planet. Even if a turret is a square kilometer, it will have to be millions or tens of millions of turrets, right? There must be various observation rooms and multiple supercomputer centers that can work together. Instead of now, as long as some turrets can be launched at one target at the same time, it will be considered as completing the task."

"The project volume of this battle star is huge! The curvature engine is just the first step, and the subsequent one may take hundreds of years."

"Now people just dig a hole to live in, what kind of planet is this?"

Lin Xuanxuan asked again: "What should I do if there are really aliens coming to fight us in the past 20 years? It seems quite dangerous to you."

Zhang Yuan smiled: "The probability is quite high... So now we are not only vigorously developing the curvature engine, but also vigorously expanding the army, mainly those type of military spacecraft at the escort level. Look, most of the soldiers laying ion cannons below are actually young people."

"………In recent years, at least 10-20% of the population will join the army. Men who are no more than 300 years old will gradually undergo militia training to reach the level of being able to fly spacecraft."

"Really or false?" Lin Xuanxuan was shocked. The promulgation of such a policy only shows that the government expects that the future political situation will become quite serious.

Zhang Yuan's expression gradually became serious: "Of course it's true! Who would joke on this kind of issue?"

"Among the large number of civilizations near Dyson's ball, the fourth-level civilization can be called chess players, and the third-level civilization is all chess pieces. We are about to leave after developing the battle star. This is what we think inside, but other civilizations do not know and will not trust us."

"They will treat us as a chess player."

"... However, it should not be fought directly. There are many big chess players, and they will not directly provoke other small chess players for no reason. But I believe that soon there will be some third-level civilizations as chess pieces to test our attitude..."

Another government staff member whispered: "What if the expectations are wrong?"

Zhang Yuan breathed a sigh of relief, "Of course it's the best. Just treat it as a self-indulgent and a false alarm. The garbage arms purchased will be eliminated in the future. It's actually nothing."

...

Time slipped away unknowingly under such intense preparations.

Next, six months passed, and the forces represented by the trading market really left.

"Goodbye, friends who are building Dyson Ball together. According to some of the agreements from our superiors, we must leave here."

"I hope we can get together one day in the future."

"I hope you can make long-term progress."

These big bugs with yellow anisoprotis skin said before leaving.

"goodbye!"

Zhang Yuan watched helplessly as the fleet left.

There are not many spacecraft in the Jihaman civilization, and there is not even a single war star. But no civilization will despise them because of this.

In just a few minutes, the spacecraft disappeared from their sight.

When the most powerful political force left the planetary system, the rest of the interstellar texts were obviously a little ready to move.

The terrible silence lasted for a month. During this period, people had no communication with other alien civilizations.

It is true that there is no communication, and you can see the battle stars and spaceships between you, but there is no information exchange.

At this time, people truly understand the weight of those ships leaving the spacecraft.

As the governors left, this starry sky seemed to return to its original wild and disorderly state.

All sounds compete for freedom in the frost sky!

A month later, electromagnetic communication finally came to the hands of the new human civilization. Several major forces invited all civilizations to participate in the discussion of "cooperation on the maintenance of Dyson Ball."

This is a bit similar to the United Nations on Earth, but it is also a historical necessity. Can't it really be a fight?
