Erecting interstellar orbits, connecting planets with peers, planets and satellites, and satellites with satellites, and interstellar spacecraft are just like the developed transportation networks of the 21st century.

Ships of all shapes and functions transport races or various supplies to get them where they are needed.

Sci-fi bases have sprung up from the ground, and countless machines are in motion, busily building on planets and moons.

The three planets were severely damaged that year, and this severity did not refer to the loss and destruction of the planet, but to the absence of magnetic fields and missing elements, resulting in no atmosphere covering the planet, no ocean, let alone an environment where organic life was born.

In order to create an environment of blue skies and white clouds, green mountains and clear waters, it is necessary to make a magnetic generator and install it inside the planet as in March, and make up for the missing five inorganic elements, so as to recreate a living planet.

I don't know what happened back then, not only the extraction of elements, but also the gravitational pull of the magnetic fields of the three planets was weakened to the point that even the gas molecules could not be restrained.

According to the understanding of earth science at the beginning of the 21st century, it is inconceivable that such a planet of this mass can occur!

During the construction process, when the bugs were exploring a satellite, they found a machine in the deepest part of the satellite that had been out of fire for many years.

Through the synthesis of data images, the machine is a sphere in the very center of the satellite. The radius of the sphere is tens of miles, the whole body is silvery, and after measurement, it is almost a regular ball. The surface is smooth, without any signs of running and starting.

Although many scientists judge that this thing should run out of energy and will not start again.

But people don't dare to be careless, and they are very cautious about the ball, which is most likely an elemental extractor. If you accidentally make it activate suddenly, the elemental gravity generated is enough to wipe out all the races that have migrated here.

They are completely unknown to the principle, structure, function, and specific operation of the elemental extractor.

It is precisely because of the unknown that it is more cautious; Because we can't travel through time and space, and we can't change the mistakes left over from the past, we must be careful, careful, and more careful on the way of exploration.

However, it is also a chance. With this Elemental Extractor, which may be left over from a high civilization, if it can be operated properly, it can make Bai Yefang's technology increase significantly.

The manufacture and operation of a machine inevitably involves a lot of knowledge, taking this possible elemental extractor as an example, it is also impossible to avoid the scientific principles of timekeeping, the material process during production, the energy during work, and the possibility of seeing the computer system used by a higher level of civilization.

Coincidentally, on the satellite of MicroOne. The bugs found a machine that resembled an elemental extractor, leaving the races on the two planets. Four machines were also discovered on the satellites of Micro-2 and Micro-3 in succession.

These four are different in color and have different configurations.

One is red, shaped like a raised ruby, pure and beautiful; One resembles a deep blue droplet, as if it were the essence of the sea; One is a trichromatic triangle, which is composed of three primary colors: red, green, and blue. There are unknown characters and patterns on three sides; The last one is a regular yellow cube with a lot of black lines on the surface, and the lines are evenly distributed and neat, cutting the cube into thousands of small cubes.

These five machines seem to be deliberately proven. There were once glorious civilizations here, or at least five different civilizations.

One can't help but wonder if it would have been a bustling place a long, long time ago. But what factors led to the destruction or disappearance of civilization here?

And if they just leave? Will they be back?

No one has a definite answer, and it is impossible to go back in time, see the prosperous days of this galaxy, and witness how they went from primitive to civilized, and then from civilization to destruction.

The technology of the second-level civilization can build a Dyson sphere based on stars, but at the time of the Gemini galaxy, there is no chance in March, and it is impossible to build one of them into a Dyson sphere.

Therefore, there are assumptions and theories, and if you really want to build, you have to spend effort to carry out accurate simulations and calculations, such as what materials are needed, how much will be consumed, how to deal with possible difficulties, how to absorb and use the energy released by stars, etc., are all problems to face in the construction of Dyson spheres.

Moreover, the races that migrated here in March generally decided to complete the transformation of the three planets first, and then proceed with the construction of the Dyson sphere of the stars for the first time.

The blue lotus star, the city of resting night, the night is boundless, the curtain of the night seems to be pulled down from the starry sky, the stars blink mischievously in the night sky, two rounds of green green, one round of fiery red moon hanging in the endless firmament.

The night breeze blows through the northern plains in spring, the faint fragrance of flowers drifts with the wind, and the lakes and rivers reflect the starlight, adding a little brightness to the whole vast wilderness.

It is precisely with these little brightness that the grassland does not look gloomy, the whistling night wind is very fast, blowing the blades of grass to shake, and the howl of nocturnal beasts spreads throughout the grassland.

Bai Chu sat in a small cabin, lit a dim oil lamp, and corrected the homework he assigned to the students during the day.

In fact, he doesn't need an oil lamp, nor does he need to carefully correct them one by one, in terms of the level of form and existence, although he is a memory puppet made by Bai Ye, he is far beyond most lives in the world.

He just remembered that there was such a long-ago picture in Bai Ye's memory, that is, Bai Ye was still in **** elementary school, whenever it was quiet in the dead of night, and everything was silent, their teachers were under the dim oil lamp, seriously correcting their homework one by one.

The mountains, the huts, the night breeze, the oil lamps, the homework, the red pen, a teacher in a coat, a serious face, this is probably the common shadow of many teachers in poor mountainous areas!

The goshawk was standing on the eaves of the window, and it couldn't figure out what Bai Chu was going to do. Gathering a group of beggar children who don't have any talent for magic and fighting spirit, teaching some weird things, it can't figure out what it's going to do, what is the purpose?

Since it couldn't think of it, it attributed it to the existence of the main god level, which was unfathomable and must have a deep meaning.

Suddenly, an unusual breath crept through, the goshawk smelled a dark fragrance, felt its body condense, and wanted to open its mouth to warn Xiang Baichu, but it was dark in front of him and he fainted.

Bai Chu's hand that was correcting homework stopped, the pen in his hand was gently put down, he frowned, the pores on the surface of his body collected gaseous molecules moving in the air, and the nanorobots in his body quickly assembled an experimental device to analyze the properties of the invading gaseous molecules.

This is a kind of gaseous molecule that has never been seen before, its composition elements are unknown, it has a strong nerve paralyzing property, according to the data reference calculation, it can paralyze all normal life below the Blue Lotus Star God Heaven Realm, and Wang Tian Realm can also be temporarily restrained for a second or two.

It's just a tie up for a second or two!

In the eyes of us ordinary people, a second is just a blink, and a word is gently spit out in our mouth, and it may have passed.

But the length of time is relative, just like the fights in Dragon Ball are often criticized, and the plot says that it takes a few seconds and a few minutes, but it can be made into a few episodes of anime.

It can be understood in this way that the speed of Dragon Ball fighters such as Son Goku has exceeded the limit, they can do a lot of things in one second, and hit punches that cannot be estimated with the naked eye, invisibly, one second in our concept is actually stretched in their eyes.

The surrounding space fluctuated, Bai Chu hadn't moved, and the surrounding environment had changed greatly, transforming into a towering mountain.

Bai Chu fixed his eyes and saw that he was standing on top of the mountain at the moment, his godless eyes fluctuated slightly, and the data gathered from around him told him that this was not an illusion, but a real space.

Hearing only a sword roar, a cloud of five-colored light was dazzling, spreading out in the gray sky, and countless sword shadows appeared in the sky one after another, forming a heavenly sword net in the blink of an eye, and the sharp chill seemed to tear through everything in the world.

On the five-color brilliance, there are six figures that are sealed, the central figure is holding a multicolored sword, closing his eyes and reciting words, the five-color streamer gathers from all over the place, and the strong momentum climbs, he suddenly opens his eyes, his eyes are colorful, ruthless and cold, the sword in his hand is horizontal, and countless sword shadows are grinding towards Bai Chu.
