220 Meteorite

Although these metal skeletons and outer armor do not have talisman formations carved on them and cannot withstand the high temperature and deep cold on the moon's surface, they can only be regarded as semi-finished products. However, this step alone saved countless time.

Although 3D printed parts have much rougher grains than those made by forging, even after heat treatment, the printed droplets are very small, and they are never as good as the parts that are cut after forging.

However, even if the material is somewhat loose, with the cooperation of several metal alloys, it is unexpectedly suitable for the lunar environment.

After these parts are produced, they will be sent directly to the base. Under normal conditions, runes will be carved and artificial muscles will be installed. These will then be wrapped with thermal insulation materials so that they can work in a vacuum environment.

Of course, the most important thing is to equip it with a brain containing the Pangu No. 1 processor and a partially simplified version of the calculation array.

The combination of prehistoric technology and Blue Star's technology makes the robots that appear on the moon much smarter than those made on Blue Star. They can complete their work independently without Xiao Ai's command.

The simplified version of the calculation talisman array is basically modeled after the earliest calculation talisman array refined by Yang Qing. Although its performance is far inferior to the latest calculation talisman array that can accommodate Xiao Ai, it can be used without Yang Qing's intervention. Refining.

Under the control of Xiao Ai, the heat in the flame array is used to melt the pure single crystal silicon, and then use a similar method to 3D printing to control the movement of silicon atoms and ion injection to form a computing unit.

Probably the biggest difference from photolithography CPUs is that the amount of various metals is very small, which is also closely related to the fact that it does not rely on the switching performance of semiconductors for calculations.

Although Xiao Ai only started refining these simplified versions of the calculation arrays after arriving on the moon, and the newly built base was full of intricate details that required her busy work everywhere, but the newly added computing power allowed her to His spiritual consciousness has reached the level of elixir formation.

This is the benefit of a weapon spirit, especially one like her, which can be upgraded by just increasing the number and complexity of calculation arrays.

Not to mention that she still fell down from the Cave Artifact Spirit, which was not inferior to Yang Qing. It became easier to recover her spiritual consciousness.

It’s not that Xiao Ai insists on adding intelligence to these robots, but in the special environment of the moon, it is temporarily difficult to popularize the Internet, and the jade slip-style space wave communication device needs to be refined. In Yang Qing’s current state, he can only It can refine several space wave base stations that combine with electromagnetic waves, and there is no time to refine jade slips on a large scale.

As each robot was activated under Yang Qing's eyes, they walked out of the base and joined the group building the base.

Yang Qing could also see that only a few hundred meters away from the base, several steel structure buildings were also building foundations.

The moon's surface has been eroded by cosmic rays for billions of years, and there are traces of radioactivity everywhere. There is no base there that is as complete as it can withstand the invasion of various radioactive elements.

Although a large part of radioactive elements only emit harmless rays such as alpha rays or beta rays when they decay, there are many more that emit gamma rays and even electrons and neutrons, which are very harmful to the human body. .

Even though the ground where the base is now located is already about five meters below the original ground, the radiation intensity, even excluding the influence from the universe, exceeds one hundred roentgens.

So the first step was to dig the ground down another twenty meters. Only then did the radiation intensity drop to about ten roentgens. valley

Although this kind of radiation is equivalent to the radiation received when flying on an airplane, it does not have much impact on the body.

After all, even buildings produce 8 roentgens of radiation every year. In the world we live in, radiation is actually everywhere, and the sun is the largest source of radiation.

The metal smelted on the moon actually contains a lot of radiation. Due to the lunar environment, a large part of the metal is radioactive isotopes.

It's just that metals like iron, titanium and aluminum are not considered heavy metals. Their isotopes only have alpha or beta rays. Although they are harmful, they are not very harmful.

Yang Qing deliberately removed part of the radioactive metal during the smelting process, but in the end there was no way to completely remove it. He could only make partial adjustments during the construction process so that the radioactive products could be discharged directly to the outside of the detected area. After all, there was nothing outside. In an obstructed environment, the intensity of solar wind and cosmic rays is much greater than them.

And during interior decoration, with a layer of organic materials containing shielding components, the interior of the new house can be free of any radiation components caused by the building.

Of course, it is absolutely impossible to have no radiation at all, because not only the signals covering the inside of the building, but also the light source are a kind of radiation, so how can it be kept away?

The entire base is operating in an orderly manner under the command of Xiao Ai. Although it is a moonlit night and the outside cannot be seen, from the drone staying above the base, you can see the entire base. From the original bare , gradually covered by buildings.

These buildings, no matter what their purpose, are expanding day by day. From time to time, a large solar panel will be put away, and then a foundation pit will be dug there to turn it into a new factory or laboratory. Of course, Maybe a hotel.

Today is the last day of the moonlit night, and Yang Qing's eyes are fixed on a picture, which is still 50 million kilometers away from Blue Star.

There is a meteorite here, which is almost three times the size of the Eiffel Tower, and its mass should be about one million tons.

This is another asteroid that has not been marked by NASA, but it was discovered by the base's optical detection radar.

In Blue Star, there is the influence of the atmosphere. Even if a large astronomical telescope can be built, omissions and distortions will inevitably occur.

This is true even for the Hubble Space Telescope in the United States. Although it is outside the atmosphere, its objective lens cannot be too large due to the rocket's carrying capacity.

Such a telescope, just like the telescope on Blue Star, can clearly observe distant places, especially large backgrounds such as galaxies, and can even discover secrets that were difficult to discover in the past.

But it is not so sensitive to those close asteroids that pose a threat to Blue Star.

After all, asteroids and meteorites do not emit light and are very fast. The time they stay on the camera will not even exceed 0.1 second. If you are not careful, you will miss them.

According to Xiao Ai's calculations, this meteorite will collide with Blue Star, and its location should be in the southwest Pacific Ocean.
