The erosion of time is the most cruel, whether it is to escape or cherish it, it will not change with the will of man.The hasty and busy six months passed quickly, and even delayed for a few days, but the people's space engineering must be over.

Professor Thomson, who is in charge of astronomical observations, has issued several warnings in succession, several large meteorites have begun to cross the Lagrange boundary, and there is a great probability that it will hit the moon, and humans must leave immediately!

These meteorites and the moon attract each other, forming a complex multi-body movement.This movement is extremely sensitive to initial values, known as chaos, and is difficult for humans to get a precise solution.But the danger is real, leaving early and safe.

In the heart of the Noah captain Yu Yifeng, there is a strong and complex parting mood, and human beings, who are about to leave their hometown, are likely to leave forever and never return.This is also the thought of many people, and when they work, they often show a sense of fainting.

But this is also helpless, human beings must go to the universe, looking for their own sky.

From the perspective of the satellite, you can see that the entire base has changed.The original round glass cover had long since been removed and replaced by a huge deep pit, a silver-white ball lying quietly in the middle of the deep pit.

It is the last home of mankind, Noah!

Too big, too spectacular, a sphere fifteen kilometers in diameter, seven and five times longer than the original base, occupies half of the entire crater.Without considering other technologies, just such a large volume can not be made by humans.

The tallest building of human beings, the Burj Khalifa, is 828 meters high, only one-eighth of it, which can be said to be a small, round ball and cone two shapes, which represent different scientific and technological content, and the circular spacecraft is the most difficult to build.

Its surface is almost completely smooth, which means that the friction is very small, so that no dust can be stained on the surface of the ship's hull, and the whole ship looks glittering and has a gripping beauty.

But because there is no friction, and it is hard enough, it has brought certain difficulties to people's construction, and there is no way to directly paste what cement and paint ah.There is no friction, and it is dropped, even the most effective glue of mankind is no exception.

Clever scientists have come up with another way, the outside can not be built, but inside can be, people build a lot of thick cement pillars inside the ship, and then extend the steel and cement from the entrance of the ship.

Relying on these extended structures, people indirectly built a lot of things on the surface of the spacecraft.Like the engine room, the cockpit, the observation room, and some laboratories.These auxiliary structures are made of titanium aluminum alloy, very light, but hard and reliable.

Yu Yifeng is even somewhat glad that the ship has more than 2,000 entrances and exits.Without this, humans wouldn’t even be able to build anything on the surface of the spacecraft.

This is the difference between heaven and earth.

To build the civilization of this ship, human beings really can not imagine its degree of development.Human beings, in the face of this super civilization, may really be similar to a grass-befect.

I have to say that this is a pessimistic thought, but it is also a fact, in the face of the vast universe, human beings are still too immature ah.

The “engine” at the bottom of the ship is a bit like a large face basin.But this "face basin" is buckled upside down, sealed with a lot of gas, and a billion-ton helium-3 nuclear bomb!

The diameter of the basin is about one kilometer, and this volume has been carefully calculated, too big and too small and not good.Do not think that the diameter of the spacecraft is 15 kilometers, the engine is so small, the ship's mass compared to its volume, really too light, the overall density is not as good as a balloon.

A small engine like that is enough.

All the instruments are doing the final test, and hundreds of testers in spacesuits are busy.

Yu Yifeng again toured the warehouse, billions of tons of ore piled up like a hill in the ship, the entire uranium resources ore was almost hollowed out, enough for humans for 20 or 30 years.The ice resources at the bottom of the ship were also harvested, and about 100 million tons of ice were obtained.The rest of the food is enough for humans to eat for two or three years.

But Yu Yi Feng still felt not enough, he always had a feeling of insecurity.Perhaps, this is the common feeling in the hearts of all people, vast space, human beings will not get any material supplement, no matter how much is not enough.

Just like when you leave your mother for the first time, you will always carry a lot of things with a large bag, and the preparation is sufficient and still nervous.

If all goes well, it will take three or four months to get Mars, and people will be able to get resources to replenish, so there is no need to be so nervous.

Yu Yifeng comforted himself and continued to patrol.

From the inside, the entire ship facility can only be said to be unsatisfactory.Because of gravity, the entire settlement is divided into three parts.The uppermost gravity is the lowest, about the same as the moon, and the bottom is the gravity of the earth.

This is because people have not yet adapted to the gravity of the earth.In this low-gravity environment of the moon, the calcium in the bones will gradually lose, the muscles will gradually shrink, if you reach the gravity area of the earth, often as paralyzed, completely unable to stand up.

Therefore, we need to have a gradual adaptation process, the first group of people to relocate, has fully adapted to the earth's gravity environment.

As for people's living environment, can not be said to be very good, after all, six months is too short, people can not build any tall buildings.Necessary life-sustaining equipment, such as oxygen circulation system, water circulation system, power system, sewage treatment system, the construction of these things will take a lot of time, there is no effort to improve the living environment ah!

In order to prevent such a treach, in order to prevent such a thing, Yi Feng simply waved his hand, and everyone slept in the tin room, even his own.

This kind of simple and easy to do the house, a few pieces of iron skin around, that is, the kind of workers in the construction site often sleep, can not be said to be comfortable, not very soundproof, but good to block it.

For this phenomenon, no one is dissatisfied, the captain Yu Yifeng himself lives in this kind of house, what can be said?Are you more powerful than the captain of Noah’s Ark?

Yes, the ship’s name is Noah because it comes from the story in the Hebrew Bible? Genesis, which means the ship that saves the world.This time, it was also a spaceship to save humanity.

“Report to Captain!The engine system is checked, no errors have been found, please indicate!"

“Report to Captain!The power system is checked and no errors have been found!”

"Captain, all the people have already arranged their homes."

...

One by one test report, no abnormalities were found.It was time to leave, and Yu Yifeng tapped his finger on the table and said with emotion: "You go to broadcast a notice, from now on, everyone will be free to move, and the time to stay on the ground should not exceed twelve o'clock."

“Tomorrow at eight, officially!”

“Yes!”

This was reported, and a large group of people got off the ship.They wear spacesuits, staggered on the moon, some take pictures of the spacecraft, some take pictures with each other, and some are sketching, and they are having fun.

People know that the time to stay on the moon will never return, so it is particularly cherished, this is the final memory.
