Ding Peng's eyes drifted to the distant sky. There were no stars here, just a dull void, where people were about to survive and develop for a long time.

At this moment, the male voice on the TV also became loud and loud: "...When the flames of the planetary engine shine in this starry sky, we will eventually embark on the road of level 4 civilization!"

Many people cheered loudly and applauded. Even other geniuses selected from the virtual world, whether used to the world or not, were raising their glasses to celebrate, wanting to give their own strength.

But few people know that the beginning of a thing is always a good thing. Especially for such a large project, if there is no bright future, how many people will have the courage to do it?

The government did not say how long the project would take eventually...

However, when nearly 20 million people consumed huge points, spent a hundred years rushing to the end, enjoying the journey and about to start a new journey, they did not know that there were nearly three thousand years of difficult times waiting for them in the future...

The loud cheers now may be the last cheers in the next three thousand years.

They will repeat the same work until they die.

The 15,000 planetary engines that humans are responsible for are equivalent to 15,000 mountains pressing against the entire civilization. Many people will have to give up their current careers and devote themselves to the vast ocean of large-scale construction projects.

They will fight with excavators and drillers throughout their lives, and through these tools, they will razed the craters to the ground.

From the beginning to cheer and laugh, then gradually become numb, and finally bringing a strong despair into the grave...

The talent training of subsequent generations will also be largely tilted towards this aspect.

A large proportion of engineers will appear, and many entertainment-related professions will be banned. Even many scientists have to give up their work, because the entire civilization will no longer have the productivity and provide them with experimental resources.

No passion can last for three thousand years. The first generation died silently. They fought for their own beliefs and ideals for life, but the second generation had to accept this situation that has become a fact, because society continued to struggle...

The third generation is still doing the same thing, and they cannot feel the ambitions of people when they first came here.

This social inertia is slowly exhausted, and then the fourth generation, the fifth generation, the sixth generation...

Even if a generation is born in fifty years, it will take the relay of 40-60 generations to survive these thousands of years.

Without any enthusiasm, they can keep 40 generations of people repeating the same work. They started to open their eyes to see the world. There were no stars or light. The huge planetary engine was ejecting plasma sparks. Until they died, they were still building planetary engines.

After living the beautiful rainbow, watching it for a lifetime has become an extremely boring thing.

But they just have to spend their whole life doing this, and they must do it seriously. The current robot system has no way to independently create a giant like a planetary engine, and a large number of people must work and maintain the entire system.

In particular, without any survival pressure, no one will force them, and there are no external enemies in this place.

The only spiritual support is that there is a certain probability of becoming a Level 4 civilization.

However, the benefits of becoming a level 4 civilization belong to all mankind, to descendants, and not to oneself.

"People have to rely on spontaneous work, and 'spontaneous' is a distant dream for us."

"So, Mr. Captain, don't consider the process of the Toss civilization for now, and don't care whether they can persevere. Our future expectations are unreliable. Although everyone's current enthusiasm is very high, the long time can always erase all the passion."

"They will gradually become lazy."

"The entire construction period is too long, so long that it makes our short-lived species desperate."

"Will you die if you don't work? You won't die! The work pressure is too small, and we can't force workers to work by squeezing their labor..."

On this day, the planetary fortress had reached its established location.

As soon as the curvature bubble was removed, the two sides immediately dispatched a large number of scientific research experts for field investigation, which is expected to last for a month.

Various large nuclear fusion flares of tens of millions of tons of tnt equivalent shine in the starry sky. These flares are like bright little suns, temporarily illuminating this dim universe.

After this, people will choose whether to stay or return.

If you want to stay here, the two civilizations will unload all the construction machinery in the planetary fortress and start formal engineering. Of course, if there is nothing special, everyone's general opinion is to stay here.

Zhang Yuan and a small number of people were worried and bet on their eyes to a more distant time.

During the discussions over the past few days, they increasingly felt that people seemed to overestimate their determination and overestimate human ambitions.

The whole atmosphere is too optimistic, really too optimistic. The plan formulated by the New Human Government has great flaws, especially in terms of personnel mobilization, which has some flaws...

"At that time, if you take a little bit of laziness, I take a little bit of laziness, the entire construction period will be delayed. If you take a little bit of laziness, I take a little of laziness, the entire civilization will immediately lose its original spirit. Although everyone knows that this project is very beneficial to humans,... humans are still a kind of selfish creature."

Optimism is a good thing. But being too optimistic can easily overestimate yourself.

Does the Empire of Sun Do Not Set Want to Decline? The Empire of Sun Do Not Set Don’t Set Want to Decline, the officials and nobles of the Empire of Sun Do Not Set Don’t Set Want to Decline, and the common people do not want to Decline.

Do Americans want to decline? Do Americans don’t want to decline either, and no one wants to decline.

"However, the decline of a country and even a civilization is not only an external challenger, but a strong competitor has continued to compete with them, but more because of its own reasons..."

"...It is because their society, their systems, policies and the mental state of the people cannot keep up with the times, which will give competitors an opportunity to take advantage of it."

"The same is true for our civilization. A civilization is dynamic and will not remain unchanged. Our policies should be changed with the times so that the entire civilization can continue to move forward. But now there is an invariant, that is, we must always adhere to this big project, which will cause great trouble to future policies..."

Faced with the suggestion of hundreds of senior officials, these civilized senior officials were all in a state of slight confusion and held special meetings specifically for this.

Finally, the captain sighed and said, "So, Mr. Zhang Yuan, what better advice do you have? We cannot force the recruitment of workers to do work for thousands of years, otherwise this government will become an authoritarian government and will be overthrown sooner or later."

Zhang Yuan smiled and said, "Of course there are suggestions. The best way is to shorten the construction period. Shorten the project volume of the original two battle stars to one. You can refer to alternative plan 17."

Option 17 is a solution designed by Zhang Yuan’s good friend, physicist Professor John.

The general plan is to build two planetary fortresses, one of which is placed at 120-200 astronomical units in the distance, to observe the collision of neutron stars, and the other to interfere with the mutual orbit between the two neutron stars, and to shorten the collision time.

Otherwise, humans will have to wait for more than 100,000 years before they can wait for the neutron star to collide, which is too long.

More than 100,000 years are absolutely unrealistic for humans. The Toss people with longer lifespans cannot wait for such a long time.

"So, this planetary fortress used to shorten the collision of neutron stars."

"But can another war star placed at 120 astronomical units be saved and not built?"

Professor John's backup plan No. 17, after careful calculation, believes that it is sufficient to build only one planetary fortress in a certain situation.

As for the current astronomical observation, there is no suitable planet at 120 astronomical units. It is best to build the equipment for observing the collision of neutron stars based on planets, so that there is a greater chance of observing the required data.

Is it possible for people to push a planet to 120 astronomical units without building planet engines?

Of course there are!

The answer is...using the huge gravity of the planetary fortress that must be built, pulling another planet over!

Since humans have to build at least one planetary fortress, let it play more roles. The first is to use its own gravity to activate the movement of another planet and bring the other planet to the target orbit of 120 astronomical units. The second goal is to do a three-body movement with the neutron star, or some other way to shorten the mutual orbit between the two neutron stars.

The universal gravitational force between the planet, like two magnets that attract each other, can form a source of power between each other.

Take the former Earth-Moon binary star system as an example. It is precisely because of the existence of gravity that both sides form a system.

The Earth-Moon system is not a simple moon orbiting the earth, but the earth. The moon rotates around the center of mass of the Earth-Moon system. However, the Earth-Moon system has a large mass and a small moon. Its common center of mass is about 4,800 kilometers away from the center of the earth, and it is wrapped in by the earth, and it looks like it becomes a simple moon orbiting the earth.

Once a large number of planetary engines are installed on the earth and the earth is deviated from its orbit, the moon will come with you, and it will be impossible to get rid of it in a short while.

By the same token, installing an engine on the moon to cause the moon to move and will also interfere with the movement of the earth.

If you really want to "wander the earth", letting the moon act as a constant source of gravity to hook the earth to run away is a relatively reliable solution. After all, the earth's thin crust cannot support those powerful planetary engines.

This is the plan No. 17 that Zhang Yuan and others suggested. Only build one battle star, start it and hook another planet, force it to suck it over, and change its orbit.

In this way, humans do not need to build a second planetary fortress, they only need to install various observation devices on this big ice hockey.

“If we shorten the project deadline by half, it will undoubtedly be good news for us.”

These officials all showed contemplative expressions. The plan sounded good, but the technical difficulty was undoubtedly one order of magnitude.

The movement of a planet is not about driving, it does not mean that you can turn left if you want to turn left, and you can turn right if you want to turn right. Under the action of its huge inertia, it may take a hundred years to turn left from turning left to turning right!

If you want to hook up other planets, you need to use your own inertia and accurately calculate it. Maybe you will bump into it by accident. This is not exaggeration!

A scientist raised his eyebrows and spoke slowly: "Mr. Zhang, in the No. 17 plan, the big ice hockey selected is quite large in size, with a diameter of 2,000 kilometers. Although its density is very low and its mass is not high... But if you want this big ice hockey to run with our planetary fortress, the distance between the two sides must be close enough to the gravity to be large enough, and the plan can be successful."

"In more than five hundred years, the distance between the two planets will reach the closest level, and there is a chance of gravity hooking. Therefore, our planetary fortress should be moved to the same height within five hundred years..."

"But if the two planets are too close... it's too dangerous! The two planets no longer circle, but are in a pattern one in front and one behind."

"Our war stars must run fast enough, and the planetary engine must have sufficient horsepower. Otherwise, the distance between the two sides will get closer and closer under the action of gravity, and they may bump into it, and then they will be all over!"

Zhang Yuan smiled and said, "Yes, it is because of this that the driving force for all human beings to work hard! If they don't work harder, the two planets will directly collide!"

"This is called work oppression. There is no oppression. I don't know how long it takes to work on such a big project. Who can guarantee that it can be completed on time and in quantity for thousands of years?"

Everyone was stunned.

Zhang Yuan continued: "But this kind of oppression is still far from enough. We still need to expand part of the population, especially in the early stages of the project, and the population must reach more than 100 million."

"Is it one hundred million?" The captain frowned and pondered. The previous plan also wanted to expand the population, but it didn't require that much.

Another professor who supported this plan took over the conversation and replied: "The construction period of the plan No. 17 is very tight, far more tense than other plans. Without an outstripping population, our industrial capacity will not be able to meet the standards."

"On the other hand, after a large population expansion, our current spacecraft cannot accommodate so many people... or in other words, after installing so many people, it will be less comfortable. Many people have to live underground, and at this time, they will feel even more oppressive when they can see the big ice hockey behind them with their own eyes."

"But……"

A member of the government think tank asked: "With so many people, it will be very difficult to escape at that time... Our Amoeba points are insufficient and we are renting spacecraft, so we can only carry 40 million people in the end."

Zhang Yuan explained: "Your problem is very good, but don't forget that people will grow old and die. In a thousand four hundred years, as long as you plan well, the final population can be reduced to less than 40 million."

The MP immediately refuted: "But that will lead to serious aging and will also cause all kinds of problems. In an aging society, the labor force will be very scarce. Maybe even the elderly have to participate in their jobs and delay their retirement age! This will cause many social problems!"

The air fell into silence for a while, or spent more than three thousand years to slowly work, and the future was unpredictable. Maybe it would take four thousand years or five thousand years to end up giving up halfway. Even if the history of new civilization is strong, it would not be possible to predict the three thousand years.

Either the project volume is cut in half, but it may have to endure a long period of aging crisis, and the people are forced and complained.

Zhang Yuan shook his head and sighed softly, "There is no way, everything cannot be perfect. Our population of 100 million has spent 400 years working hard and increasing the working time a little, so we have to complete about 40%-50% of the project volume, and we can only hand it over to future generations."
