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

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

Jilin Xuanxuan felt that her forehead was sweating, and hurriedly issued a series of instructions. Nowadays, the human-computer interaction technology has been quite developed, and the bionic hand in the glass helmet wipes off this sweat very accurately.

"Not necessarily...... In the end, it depends on how the project is planned. Zhang Yuan said: "If the curvature engine is to be installed in this place, the geographical appearance will still be destroyed." ”

It took about 12 hours for the group to finally reach the 28,000-meter-high mountain out of breath.

After exercising for so long, even in a low-gravity environment, even if there is a power armor, I am still tired enough.

At this height, you can clearly see the horizon in the distance, a looming Dyson ball, hanging in mid-air, it gradually blooms its own bright light, completely illuminating the land.

It took hours before it slowly dimmed.

This wonderful, cyclical change of illumination can spread throughout the galaxy over time.

Zhang Yuan has been looking at the Dyson ball for a long, long time.

The addition of a new production line has significantly increased the speed of development for engineers who are busy on a distant human construction site. However, there is still no way for ordinary people to distinguish whether industrial production capacity is rising or falling with the naked eye, and only internal staff will appreciate the convenience.

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

These towers consist of a total height of 64 km, which can be much higher than Mount Olympus!

They are all rigid structures, thanks to the small size of the planet, the gravity is only half that of the moon, and the emergence of various super materials, human rigid body buildings can be stacked so high - these materials are basically the limit of conventional materials.

At the top is a circular instrument, a planetary curvature generator, that works in tandem.

Basically, the structure of the planetary curvature engine of each level 4 civilization is roughly like this.

And such planetary curvature engines need to be built at least 900 around the world, so the amount of work is quite large, and it will take people to work overtime day and night for 20 years of hard work.

Standing on the high mountain and looking into the distance, watching the comings and goings of flying cars and trains, there is a feeling of seeing the mountains at a glance.

At the nearest construction site, a group of soldiers were installing the purchased munitions, which could be seen as an ion cannon through a long pipe.

The performance of this thing is not very good, and it will not be specially built for a deep defensive foundation, just lay it on the surface, and it can be used after connecting to energy.

One of the climbers who was traveling with him, there happened to be a man in charge of this work, and he said: "It is estimated that 200,000 such ion cannons and 300,000 laser weapons will be placed, which can be regarded as giving the battle star a little combat effectiveness...... The amount of arms purchased alone is not enough, and we have to make some of them ourselves. ”

Zhang Yuan smiled bitterly: "There is no money, if there is money, we will definitely buy more." ”

"Solve the problem first, and then find a way to solve the quality problem. Combative and combative are two different concepts. ”

"Is the situation so serious?" Several other people, all government workers, also came together to hear their discussions.

"Yes, this time to hide from everyone, the situation may be quite serious. Even if we make a mistake, it's good to plan ahead."

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

Zhang Yuan explained: "Of course it's not enough! You have to think about it, this is a planet, even if there is one turret per square kilometer, there must be millions of turrets, right? There must also be various observation rooms, and there must be many supercomputing centers that can operate together. Instead of now, as long as some turrets can fire at the same target at the same time, the mission is completed. ”

"This battle star has a lot of work! The curvature engine is only the first step, and the followers may be hundreds of years longer. ”

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

Lin Xuanxuan asked again: "What should we do if aliens really come to fight us in the past 20 years?" It sounds like it's dangerous. ”

Zhang Yuan smiled: "The probability is quite large...... So now we are not only vigorously developing the curvature engine, but also vigorously expanding the army, mainly that kind of escort-level military spacecraft. You see, most of the soldiers laying the ion cannon below are actually young people. ”

“…… At least 10-20% of the young people who have graduated in recent years will join the military. Men over the age of 300 will gradually undergo militia training to reach the level of being able to fly spaceships. ”

"Really?" Lin Xuanxuan was taken aback, the promulgation of this policy can only show that the government expects the political situation in the future to become quite grim.

Zhang Yuan's expression gradually became serious: "Of course it's true!" Who would joke on such an issue. ”

"In a large number of civilizations near the Dyson sphere, only the fourth-level civilization can be called a chess player, and the third-level civilization is all chess pieces. We're going to leave after developing the Battlestar, and that's what we think internally, but other civilizations don't know about it and won't trust us. ”

"They'll treat us like chess players."

“…… 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 some third-level civilizations will test our attitude as pawns......"

Another government worker whispered, "What if the expectations are wrong?" ”

Zhang Yuan breathed a sigh of relief, "Of course, it's the best, just treat it as self-inflicted and false alarm." The junk arms purchased will be eliminated in the future, and it is actually nothing to spend some money to buy peace of mind. ”

……

Time slipped away imperceptibly under this tense preparation.

Then, six months later, the forces represented by the trading market really left.

"Goodbye, friends who built the Dyson Sphere together. According to some agreement from above, we have to get out of here. ”

"May we be able to meet one day in the future."

"May you make lasting progress."

The big bugs with yellow spiny skins said before leaving.

"Goodbye!"

Zhang Yuan watched as this fleet left.

There are not many ships in the Thornhaman civilization, and there is not even a single battle star. But no civilization will despise them for this.

In just a few minutes, the ships disappeared from view.

When this most powerful political force left the planetary system, the rest of the interstellar civilizations seemed to be a little ready to move.

The terrible silence lasted for a month. During this period of time, people did not have any communication with other alien civilizations.

There is no communication in the real sense, and you can see the battle stars and spaceships between each other, but there is no information exchange.

At this time, people really understood the weight of those few ships leaving the spaceship.

This starry sky, with the departure of the ruler, seems to have returned to the original state of barbaric disorder.

Freedom of the Frost Heavens!

A month later, electromagnetic communication finally reached the hands of the new human civilization, and several major forces invited various civilizations to participate in the discussion of "cooperation on the maintenance of Dyson spheres".

This is a bit similar to the meaning of the United Nations on the earth, but it is also a historical necessity.

After much deliberation, the New Humans sent diplomats to the site, only to be greeted with some not-so-good news a few days later......
