Looking at the information given by One, and the constantly rotating map in front of him, the glittering asteroid belt is very conspicuous in the hologram of the solar system.

Then Dong Chen looked at the edge of the solar system again, looked at the circle of asteroid belts there and muttered, "Actually, the Kuiper belt located outside Neptune is also quite suitable, it is farther away from the earth, and there are very few moons on the earth passing there, which is very conducive to us hiding there for secret development." ”

"But it's really too far away from the earth, and it's also far from the sun, and if something happens to the earth, it's not very convenient. When it comes to a real emergency, the consequences of an extra minute delay are quite terrible. ”

After speaking, Dong Chen looked back at the asteroid belt between Mars and Jupiter, nodded and confirmed, "It's still appropriate here." ”

"Located in the middle of the solar system, not far from the Earth and not far from the edge of the solar system."

"Advance can be attacked, retreat can be ......"

"Ahem, if something happens on the earth, the spacecraft we built can rush to the earth faster to support, and basically do not delay the concealment effect, and the artificial satellite visits here not much."

"If there is an uninvited guest from outside the solar system, then our spacecraft can also respond immediately, and can even bring them a surprise encounter on an asteroid."

"It was just perfect."

"Yes, sir," said One, too, "if you were to rule it out, only the asteroid belt between Mars and Jupiter would be suitable for your ship-building plan. ”

"Then don't worry about it," Dong Chen said firmly, "One, you mark the positions of Ceres, Vesta, Zhishen and Marriage in the asteroid belt for me, and I'll see their actual positions and operating status." ”

"Also, mark their size and composition, and by the way, enlarge their holograms appropriately, otherwise I won't be able to see clearly."

"Okay, sir, process the image to display."

With No. 1's answer, the hologram of the solar system in front of Dong Chen changed.

There were suddenly four more points of light in the asteroid belt that originally had bright edges to indicate prominence, and the four bright spots quickly became larger, and then they became the four largest planets in the asteroid belt that Dong Chen remembered.

These materials are all brought by Dong Chen from the earth, after all, in the world of ship-selling citizens, the solar system is no longer the solar system it used to be, and the asteroid belt has long been developed in the early development of mankind, so the solar system hologram here cannot be used as a reference on the earth's side.

"Ceres is the smallest and only dwarf planet in the solar system to be located in the asteroid belt, and the first planet to be discovered in the asteroid belt. It has a rocky core, and the mantle layer contains a large amount of icy water material, with an average diameter of about 950 km. ”

"Vesta, one of the largest asteroids in the solar system. It has a metal core dominated by iron and nickel, covered with an olivine-dominated mantle and rocky crust, and is an oblate sphere affected by gravity, with an average diameter of about 525 km. ”

"Homo sapiens is the second asteroid to be discovered, with a composition similar to that of a carbonaceous chondrite, composed mainly of silicates, oxides and sulfides, with an average diameter of about 520 kilometers."

"Marriage is an S-type asteroid composed of heavier stony with the components of chondrites on its surface, as well as iron-containing silica hydrochloric acid, which is found in ordinary stony meteorites, and is about 240 kilometers in diameter."

Looking at the actual data displayed by No. 1, and then looking at the orbital operation of the "behemoths" in the four asteroid belts, Dong Chen thought for a while and said, "There are no human artificial spacecraft near these four planets, right?" ”

Hearing Dong Chen's question, No. 1 clicked next to Ceres, and then pulled his hands, and a holographic model of an artificial satellite appeared next to Ceres.

After showing the artificial satellite to Dong Chen, No. 1 said, "At present, there is only this "Dawn" asteroid probe of the United States, but it has used up all the fuel in the fall of 2018 and has lost its ability to work. ”

"That's good, I just observed their orbital status," Dong Chen looked at the four magnified planets, "I plan to build an industrial zone on each of these four planets, divided into four development bases, including a spaceship manufacturing plant and a material supply factory, as well as an interstellar defense line." ”

"The four planets are basically in four directions in the process of orbiting, although they sometimes coincide due to the speed of operation, but basically most of the time they can ensure that they can be seen in all four directions."

"I feel that the danger of the big filter is not only the "natural" hazard in the galaxy, it is very likely that it will also encounter a relatively strong alien civilization, and the civilization of this galaxy has been destroyed by other galaxy civilizations, which should be considered a successful filter. ”

"So we have to guard against this."

"Okay, sir, this message has been recorded, and when the time comes, I will divide all the equipment into four parts and prepare for the foundation construction." Number One said next to him.

Hearing this, Dong Chen nodded, and after determining the problem of base construction, he thought of the mining ships used to collect mineral deposits after the base was built, the military ships used for attack and defense, and the problem of colonial ships that might be used to run away in the future.

These three types of ships are the basic ships in the whole plan, and they are also the most used ships, and other types of ships can be slowly produced in the future, but these three types of ships must be the first to determine the plan and produce.

And the configuration of these things will definitely not be at the same level as those prepared by the Arc Group, if it is the same, then it will be in vain to prepare this third insurance.

The plans just announced by the Arc Group seem to be a lot, but they don't involve the key interstellar migration ships and interstellar warships, and they are basically based on developing strength and exploring the solar system, so these three plans are not duplicative and conflicting.

What Dong Chen has prepared on his side is all world-level technology for ship-selling citizens, and they are all technologies that are much more advanced than those of the earth.

At that time, if it is a civilization of the Atlantis level or higher, then Dong Chen is not worried at all, and he can definitely fight back or even eliminate it.

But if it was a civilization that was more advanced than the citizen world that sold ships, then Dong Chen would have no choice.

After all, he has prepared the best, and if he can't beat it, he can only be regarded as ruthless.

Thinking of this, Dong Chen didn't look at the hologram of the solar system, but looked at No. 1 and asked, "There is no problem with industrial robots and parts of various factories, and I remember that there are several ready-made manufacturing solutions for military ships and mining units, although they are all a little small." ”

Wen Yan said, "Yes, sir, do you want to check it out?" ”
