The last human in the universe

Chapter 66 Personal expedition
Facing the silent officials and committee members, Zhao Changxing said slowly: "In the education system, all teachers have been transferred to the construction team.

Among the students, teenagers who are over 12 years old and under 14 years old spend half a day every day to take care of younger children, and undertake some simple maintenance tasks in the Tinder spacecraft and the base.

Among the teenagers who have reached the age of 14 and are under the age of 18, they spend 4 hours a day to participate in the construction task. In the rest of the time, they spend [-] hours resting, [-] hours studying, and [-] hours participating in the spaceship. Maintain tasks with the base, or become a teacher, cooperate with Xiaoxi to educate younger children, or participate in some more difficult spacecraft maintenance tasks.The last four hours are left for my own chores. "

Facing Zhao Changxing's arrangement, everyone turned pale with horror.

No matter how heavy the construction tasks are, minors do not need to participate in labor. This is an iron law that has lasted for hundreds of years.But now, Zhao Changxing broke it.

"At the critical moment of the life and death of civilization, everything should put the interests of civilization first. Without civilization, no matter how well we protect the children, it will only make the enemy more slaves, or let the space have more corpses." Zhao Changxing Whispering: "The interests of civilization are above everything. Above morality, law, human rights, emotions, etc., everything."

"Yes."

The newcomers, who were like flowers in the greenhouse, felt something new and different from Zhao Changxing's harsh attitude and words.This caused a great shock to them.

If all goes well, then, for a long time, the children who grow up during this period of war will have a unique growth experience in the entire history of new mankind.

As for what kind of impact this will have on their lives and their growth trajectory, that is beyond what can be judged now.Zhao Changxing only knows that he will adjust the policy flexibly according to the development of the situation and the changes of the situation.

Under Zhao Changxing's call, everyone, even some underage children, devoted themselves to combat preparations.Of course, for the general public, they don't know that this is preparing for war, they just think it is preparing for the voyage to the inner solar system.

The entire Sedna planet, including the atmosphere in various space bases, once again became serious and dignified.Countless people are in a hurry, and countless factories are roaring day and night.

Under such circumstances, one standard container after another was thrown by the No. [-] space elevator launch pad in the direction of the inner solar system.

The appearance of the TEU is similar to the container of the earth age, only bigger.On average, about 100 tons of materials can be loaded in a standard box.

It is equipped with a simple propeller, and after obtaining the initial speed of advancement, the propeller will immediately start to decelerate.Under the control of the automatic control equipment, after arriving at the scheduled construction site of the space carrier, they will just decelerate to a relative speed of zero.

The scheduled construction site of the space carrier is about 200 million kilometers away from Sedna.It is in an orbit around the sun.

Because Sedna's rotation period is 10 hours, people have an opportunity to send materials and personnel to the construction site every 10 hours.And every launch, people will launch 200 standard boxes, with a total mass of about [-] tons.

These standard boxes themselves are also qualified construction materials, so the people responsible for building the space carrier do not need to send them back.People only need to process them again in the foundry, and then they can be turned into various parts and integrated into the space carrier.At the same time, each standard box is painted black, which will not reflect light at all, and the surface is coated with the most advanced stealth material to reduce the probability of being detected by spy satellites as much as possible.

Even if they were detected in the end, Zhao Changxing wasn't really worried.After all, they are headed towards the inner solar system rather than deep space stars.No matter how the deep space stars think, they will only think in the direction of the inner solar system, and will not suspect that this is an action against themselves.

After really pulling out all the stops this time around, new calculations soon appeared again.This time, the estimated construction period of the space carrier has become 7.6 years.

This length of time can already meet Zhao Changxing's request.

"This is an all-or-nothing battle for survival." Zhao Changxing thought silently in his heart: "We have done our best. Victory will definitely belong to us."

Zhao Changxing didn't think about what to do if he failed.Although all war thinking emphasizes that one should think about defeat before thinking about victory, one must leave a way out for oneself.But now it is clear that human civilization has no way out.

Either succeed or perish, there are only two paths.

A few months ago, the first batch of trained engineers, skilled workers, and soldiers had already sneaked to that place in standard boxes.They brought the first batch of instruments and equipment, and now they have begun to use the materials that arrived in the early stage, and started to build the skeleton of the space carrier.

In the design, the first space carrier in the history of new human civilization adopts a construction style similar to that of the Tinder spacecraft.This is not a coincidence, but this design has advantages that other construction styles at the current stage cannot match.

Its long central axis can be used to build a large number of warehouses, park a large number of combat spaceships, and build numerous facilities.The circles revolving around it can create gravity suitable for human survival.No matter from which point of view, this style is the most suitable.

After 4 years of wartime control, the overall skeleton of the space carrier was completed.Its total length exceeds 1 kilometer, and there are 2 circles on it, each with a diameter of more than 300 meters.In addition to facilities such as field hospitals, canteens, and dormitories, these two circles also store a large number of materials that require special environments to store.On its central axis, many facilities are densely integrated, such as docks, material warehouses, and fuel centers.

Of course, none of these facilities have been built yet at this stage, they are just reserved places.

After the overall skeleton is completed, the next step of construction begins immediately.The construction of this step means a huge amount of materials.People need to carry enough food for 500 people to eat for more than ten years-these 500 people are all the people who participated in the interstellar expedition, including 90 spaceship pilots, and the rest except the commander, most of them are logistics personnel.

In addition to food, medicines, medical consumables, spaceship spare parts, etc. are also needed. There are tens of thousands of various materials.Among them, the most important category is undoubtedly fuel.

The main body of the space carrier supplies energy through the fusion reactor, but the propulsion method still needs working fluid.Based on comprehensive calculations, it is still more economical to use methane and liquid oxygen to burn and inject gas.

In addition to the fuel to drive itself, it needs enough fuel to fly 30 combat ships.Comprehensive calculation, the total mass of fuel is as high as several million tons.

And this, in the calculation, is only enough for the space carrier to sail to the combat location and complete the operation, and there is no fuel for the return trip.

Yes, Zhao Changxing didn't think about the return trip at all.The first reason is that it is impossible to carry so much fuel, and the second is that once the battle fails, even if it returns, it will be meaningless.

In this battle, if you fail, you will be benevolent.Zhao Changxing has already shown the courage to break the boat.

In this battle, he will personally serve as the combat commander and follow the soldiers to the front line.If not successful, he will not come back.

If the expedition is successful, people will have time to wait, whether it is getting fuel on the deep space star or waiting for the fuel to be sent from Sedna star.

The standard boxes one after another flowed into the deep space like flowing water, turned into parts one by one, turned into warehouse after warehouse of materials, turned into ammunition, medicine...

Time flies by.With two months left before the scheduled time, the construction finally came to an end.

All personnel, supplies, spaceships, weapons and ammunition, equipment, etc. are all in place.Zhao Changxing has arrived at the No. [-] space elevator ground base and is ready to go.

In this battle, apart from Zhao Changxing, half of the members of the War Committee, including Wu Qinghong, who has been performing well in recent times, will follow him on the expedition.The remaining half of the members of the War Council and all government officials will stay on Sedna.

Looking at the officials who had become thinner day by day, Zhao Changxing was filled with emotion.

During these years, people generally lost more than 5 kg in weight.Carry out comprehensive combat preparations, and the slight signs of obesity that just appeared before the wartime control have disappeared without a trace in the past few years.

Zhao Changxing wanted to say something, but he didn't say anything.After a long silence, facing the people, he finally said only one sentence: "Take care of your home and wait for me to come back."

All the remaining war committee members and human government officials stepped forward at the same time.

"Guaranteed to complete the mission!"

Zhao Changxing waved his hand, took the committee members who followed him on the expedition, boarded the passenger compartment of the No. 200 space elevator, and set off for the first space carrier in the history of human civilization, which is [-] million kilometers away.

Deep space star, Tianshen base.

Recently, with the restoration of the deep space civilization's control over the planet, the scale of the Tianshen base has been rapidly expanding.In particular, the electromagnetic railgun was finally put into use, which provided a powerful boost for the follow-up construction of deep space civilization.

Seeing the prosperity of civilization, the rapid increase of population again, and the smooth progress of science and technology, almost everyone felt more and more relaxed.

Under such circumstances, a piece of information was submitted to Nuoli Ruoxi's desk by the staff of the War Temple.

"There is evidence that human civilization has been carrying out large-scale construction activities for unknown purposes recently? Hmm..."
