The last human in the universe

Chapter 45

At this moment, the last obstacle to the construction of chemically fueled spacecraft has also been solved.After hearing about the specific process of solving the problem of high-performance special steel, Zhao Changxing felt a little ironic.

Of course, he would not interfere with these matters.However, he still silently blessed Hu Ming from the bottom of his heart.

After solving this problem, the engineering department immediately started specific equipment research and development.It is expected that the first spacecraft will be built in just a few months.

During this period of time, the second phase of the human city project is also progressing steadily.Zhao Changxing didn't pay much attention to those natural landscapes, where the residents lived and so on.What caught his attention the most were two special buildings.

These are two 60-story, 200-meter-high magnificent buildings.

The tops of them are directly connected to the "sky" of Human City, and the bottoms are more than 170 meters deep underground.Excluding the area occupied by the building itself and some public areas, the average usable area per floor is as high as 2.5 square meters.

60 floors, that is a total area of ​​150 million square meters.The two buildings have a total of 300 million square meters.

Of these two buildings, one is a dedicated planting building, and the other is a mixed building for planting, livestock and aquatic products.

That's right, Zhao Changxing made a big move.The research conclusions of the Earth Age experts told him that the more dispersed, the harder it is to manage and the lower the efficiency.Conversely, the more concentrated, the higher the efficiency.Zhao Changxing directly gathered all the needs of food, meat, aquatic products, etc., and put them all in the Human City.

These two buildings can produce nearly 1 tons of wheat and 1.2 tons of rice every year, and countless vegetables, fruits, cotton, soybeans, corn, oilseeds, sugar beets, etc.Not only can it fully meet the food demand and feed demand at the current stage, but it can also greatly meet a considerable part of industrial demand.

The same is true for the Animal Husbandry and Fishery Building.Not only can it meet all the meat needs of people, but the leather and hair produced can also be used for industrial purposes.

In particular, their degree of automation is extremely high. Two such magnificent buildings only need less than 50 people to maintain their operation.

With these two buildings, Humanity City is truly a well-deserved human center.

Zhao Changxing put a lot of energy into this matter and has been following its progress almost all the time.Its significance to the entire human civilization is too great to be taken lightly.He didn't turn his attention to other things until the main structure of it was complete, leaving only the interior "finishing".

At this moment, the first chemical fuel spacecraft was finally built after possessing high-performance special steel.

The first test machine has a total height of about 4 meters and a diameter of about 6 meters. Its shape is roughly similar to a straw hat - the upper cylindrical space is the cargo compartment, and the lower brim is where the engine, propeller and fuel tank are located. .

It does not design a manual console, but a full remote control.There is also no dedicated cabin, and no life support system.Of course, if people need it, they can also put on spacesuits and stay directly in the warehouse, and they can also fly into space.

It uses methane and liquid oxygen as fuel - liquid oxygen, of course, oxygen is indispensable no matter what fuel is used.The reason for choosing methane is because there are a lot of methane reserves on Sedna.

Thorin can obtain a huge amount of methane through simple processing.And Thorin is everywhere on Sedna.

It is full of fuel, and each launch can transport about 15 tons of materials into space, and then the remaining fuel will land for reuse.

Of course, this is only on Sedna.If it is on the earth, even if this thing is not loaded, it will fall when it flies to a height of 2000 meters.

Under Zhao Changxing's gaze, the director of industry nervously pressed the start button.In an instant, bright flames shot out from under the "brim of the hat", propelling it into the sky staggeringly.

It was slow at first, but quickly picked up speed until it disappeared from sight.

Its running track is still displayed on the display screen in front of it.The people on duty on the Ignition spacecraft are also monitoring its traces remotely.

Under the control of the preset program and the command of people, it took more than ten minutes to complete the acceleration and deceleration process, and finally successfully arrived at the Tinder spacecraft, and successfully delivered today's supplies - 1 ton of flour, 1 Tons of rice, 3 tons of vegetables and 100 kilograms of meat were delivered to the children.

After that, it left the Pylon spacecraft again, began to decelerate and landed, and finally landed near the launch point.It's just...it fell obliquely.

It hit the ground so hard that its entire body was flattened.

Cold sweat immediately came out of the director of industry's face.Zhao Changxing was very happy, not only patted him on the shoulder, but also praised loudly: "You can successfully land in the first test flight, you did a good job! It's just a few small problems, just solve them. Come on, try to get them out sooner." A mature model is coming!"

"Yes Yes."

The director of industry wiped off his cold sweat and forced a smile on his face.

Since then, research and development work has continued.After the second, third, and sixth test flights, after two years of "decoration" work on the interior of the two buildings in the human city, the mature chemical fuel spacecraft was finally built.

Now it's out of control.In a short period of time, ten of this model, named "Flame" by Zhao Changxing himself, were produced.

The first batch of building materials is also ready to go.Relevant space workers have also been trained.Thus, the Tinder spacecraft expansion project officially began.

If it runs non-stop 24 hours a day, excluding the maintenance time, a Flame transport ship can make two round trips between the human industrial zone on Sedna and the Pyro spacecraft on average.On average, about 13 tons of materials can be transported in one trip, and a full 260 tons of materials can be transported in an average day.The materials needed to build a new circle that can accommodate 700 minors for the Tinder spacecraft can be transported in less than two years.

Of course, this is just the beginning.The Flame transport ship is still being built, and the transport capacity of humans is also increasing rapidly.

In addition to transportation and specific construction, two years later, the first newly added circle layer was successfully completed.

During this process, 4 astronauts unfortunately died due to accidents.Although they knew in their hearts that this kind of thing was inevitable, people's hearts, including Zhao Changxing, were still full of sadness.

Zhao Changxing personally presided over the memorial service for them and awarded them the Medal of Honor.Their names will also be recorded in the history books of mankind for future generations to pass on.

At this time, the two buildings in Human City were finally completed.As a result, a large amount of grain began to be produced continuously, and with enough grain as a backing, the prohibition on alcohol that had been implemented for more than 100 years was finally loosened.

After stipulating a series of prohibitions such as no drinking during working hours and no drinking in public places, commercial wine finally began to be sold and was warmly welcomed by people.

In fact, from a rational point of view, Zhao Changxing was unwilling to let this thing appear.After all, drinking mistakes is not an empty talk.But still the same sentence, people are people, not tools.It is impossible to expect people to maintain mental stability without enough entertainment.

Prohibition of alcohol has never been successful in the entire history of mankind.Zhao Changxing certainly didn't think he could succeed on Sedna.In particular, at this stage, some people have even begun to secretly use industrial alcohol and medical alcohol to enjoy themselves, and the strict prohibition on alcohol is even more impossible to continue.

Of course, Zhao Changxing would never touch this thing.Not only that, but he will never marry, never raise children.

If he can't live forever, but only has a lifespan of a hundred years at most, then under the premise that conditions are met, he is happy to start a relationship, get married and raise a few children.

But it seems that I can really stay young forever...

Then, under the premise that I must be the leader of human civilization for an extremely long period of time, getting married and raising offspring means the emergence of an interest group around myself-this is not transferred by personal will, Rather, it will inevitably appear.Once such interest groups appear, the overall development of human civilization will be affected.

This was absolutely unacceptable to Zhao Changxing.As early as when he first set off from the earth, he had already made up his mind to dedicate all of himself to civilization.

So he can only go on alone.

But he didn't think it was a problem for him.The reason is simple. Watching the growing strength and prosperity of human civilization can bring him spiritual enjoyment far beyond a relationship.

In this respect, the interests of human civilization highly overlap with his personal interests.

At this moment, the first newly added circle layer was officially completed, but it was not put into use immediately, but served as a temporary transfer station for materials.In this way, the construction speed of subsequent circles can be increased again.

The number of flame-type spaceships has also increased to 20, and the number continues to increase.So only one year later, the second new circle was also built.After that, the third one, the fourth one... until the 50th one.

Among them, one circle is specially built as a medical center, one circle is used as a material transfer and equipment maintenance center, one circle is used as a warehouse, and two circles are used as activity centers.The remaining 45 circles, together with the original 5 circles, are all devoted to the task of raising minors.

At this moment, in the entire Tinder spacecraft, a total of 3.6 minors can be raised at the same time.On average, up to 2000 people come of age each year, thus replenishing Sedna.

It is now May of the 175th year of the new calendar.At this time, the population of human civilization officially exceeded the 5 mark.
