As Su Meng builds new structures and buildings day by day, Su Meng's new spaceship is getting bigger and bigger.

At the beginning, Su Meng designed all the characteristic environments on the earth, and then designed the environments of some other planets in the solar system, and the decks of each spaceship were all different styles, and none of them were repeated.

After about two years, Su Meng was finally about to start building the final spaceship shell.

There was already enough space for the twelve main ion engines before, and at this moment, when Su Meng built the shell, he would also build the twelve main ion engines.

For the shell of the spaceship, the design adopted by Su Meng is still a seamless design, and it will not be possible to enter the spaceship by normal means, unless Su Meng personally uses the power of the rules, he can enter and exit the spaceship.

This is mainly to improve the safety of the spacecraft, after all, in space, any danger can happen.

Su Meng finally went through the simulation design of the spaceship shell in his mind, and after confirming that there were no defects and omissions, he began to manufacture the spaceship shell and main engine.

The outer shell of the spaceship is also made of compressed atomic aluminum, which is the result of the peak of the Nebula civilization, extremely strong, with 20 times the hardness of diamond, and the basic material used by Su Meng's spacecraft is this compressed atomic aluminum.

Su Meng was in front of a huge round pillar and began to build.

The shell of the spaceship, which was more than 100 meters thick, began to be manufactured by Su Meng little by little.

One hundred and sixty-eight meters, Su Meng designed the spaceship's shell to this thickness for a reason.

Because the material is made of compressed atomic aluminum, even if the ship's front collides with an asteroid of the same size, there is only one, the ship is intact, and the asteroid is smashed into powder.

And Su Meng has an ability domain with a radius of five hundred meters, and she can move instantly within this radius of five hundred meters, directly on top of the rules of space, ignoring physical barriers, as if she appeared in another space at the same time as she disappeared in this space. It's not spatial folding, it's not spatial cracks, it's not time stopping, it's the movement of real spatial reproduction classes.

It can be said that this kind of spatial movement is based on the rules, and the part between the two spaces has no effect on Su Meng.

This meant that she could walk directly from the outside of the ship into the spaceship, ignoring the physical barriers.

Of course, she can also make the ship's shell automatically crack the cracks from the physical level, and then go inside and fill the gaps.

It's just that the energy consumption of the old spaceship is not much, and the shell of the new spaceship of more than 100 meters will consume terrifying energy, which is not cost-effective compared to space movement.

Therefore, in Su Meng's plan, in and out of the new spaceship in the future, he will directly use space to move in and out.

As long as the thickness of the shell of the new spaceship does not exceed five hundred meters, then there will be no obstacle to Su Meng's entry and exit.

Even if the thickness of the shell was more than five hundred meters, if it was really necessary, Su Meng could still enter and exit the spacecraft in two or more stages from the material level.

Another reason why it is made to a thickness of 168 meters is that under Su Meng's simulation, a spacecraft of this weight will be able to meet the needs of a maximum speed of 50% of the speed of light.

If it is thicker, the mass of the spacecraft increases, and the material strength is the same, it becomes fragile and cannot withstand 50% of the speed of light.

Soon, Su Meng was about to start manufacturing the first main engine of the spaceship, and the first of the twelve main engines, which was named Engine No. 1 by Su Meng.

Engine 1 is designed like the other 12 engines, with a maximum diameter of 200 meters and an extremely complex structure inside. If humanity is not extinct, it cannot be made at all.

But for Su Meng, her energy conversion manufacturing method does not have any pressure in the face of this complex process.

Su Meng came to the vicinity of the predetermined position of Engine No. 1, a light of energy flew out of her body, connected to the stand, she closed her eyes, and Engine No. 1 began to generate under the control of her mind.

In a few minutes, Engine No. 1 was perfectly built.

Engine No. 1, which has not yet started, looks like an inverted cone structure more than 600 meters long, embedded in the outer shell of the spaceship, with a huge ion vent, which is pitch black and deep at the moment.

A shield will also be created outside the vent of Engine 1.

The shutter is usually tethered to the outer shell, but when the spacecraft enters inertial navigation, the shutter will pop out, blocking the vent of Engine 1 and preventing damage to the engine by possible cosmic dust.

The shutter is shaped like the blade shutter of a camera on Earth, is generally circular and retractable, and consists of a half-crescent-shaped tooth cut from it, and is designed because it opens and closes the fastest, and efficiency should be the optimization criterion in terms of mechanical design.

Su Meng began to make it, and after it was manufactured, it was tested.

As Su Meng pressed the switch to turn on the baffle, countless arc-shaped toothed blades popped out of the No. 1 engine nozzle, rotated, and shrunk, protecting the No. 1 engine.

The shutter closed successfully and took 19 seconds to close.

It then opened, re-revealing the nozzle of Engine 1, in 15 seconds.

The reason why it takes different times to open and close is that you need to be more careful when you close it to be perfect.

This difference is pervasive in the universe and seems to imply that the universe is not standing still and expanding, but rotating.

However, the research of cosmology, human data are all speculation, and they cannot be trusted without field investigation of scenes outside the universe.

It's as if before humans actually realized that the earth was round, some people guessed that the earth was round, and some people guessed that the earth was square.

Although the manufacturing time of the shell was not long, it was not short, and it took Su Meng a full forty days to successfully manufacture the twelve main engines and the shell with a diameter of 6,600 meters.

The shell of the human future is white, and white means higher recognition, which is undoubtedly very dangerous and unwise in the universe.

How do you know that you are the only life in the universe? Western scientists have been insisting that before the discovery of extraterrestrial life, the Earth was the only planet in the universe where life existed. It can only be said that this is not a science, but a religion.

From the geocentric theory, to the heliocentric theory, to the galactic center theory, to the only living planet theory, it is a continuation of this religion.

Su Meng has never felt agreed with this statement, she thinks it is better to be cautious and cautious, and to keep a low profile until she is sure whether she will encounter other civilizations.

So when Su Meng began to make the outermost paint of his spaceship, he decisively chose a black material that could absorb electromagnetic waves.

The material comes from a ruin of the Nebula civilization and has 99% visible light absorption, 99% infrared electromagnetic absorption, and 78% X and gamma ray absorption.

The reason why the efficiency of absorbing high-energy rays is relatively low is that the energy level of such high-energy rays is too high, and it is difficult for ordinary matter to be able to absorb this energy without being damaged itself.

With this all-black absorbing paint, the probability of Su Meng's spaceship being discovered is reduced by hundreds of times.

The observation equipment on Su Meng's new spacecraft has been simplified, and there is no need to create a huge number of telescope arrays, because Su Meng realizes that with her current technology, even if she creates a huge observation array, it is equivalent to being in vain and blind. Therefore, only the basic twelve radio telescopes and thirty-six optical telescopes were retained, and the twelve radio telescopes were set up on the hull of the spacecraft, evenly distributed, and next to each radio telescope, three optical telescopes were set up.

The entire ship was covered in paintwork, and it became pitch black, almost blending in with the background of the starry sky.

The specially constructed radio telescope is hidden above the ship's sleek hull, making it impossible to see any difference from its surroundings.

Optical telescopes are hidden behind black filters.

The new spaceship has been completed at this point, and Su Meng is ready to disassemble the old spaceship and take it away.
