Chapter 647 Guards from all directions

Looking at the information given by No. 1 and the constantly rotating map in front of him, the shining asteroid belt was very conspicuous in the hologram of the solar system.

Then Dong Chen looked at the edge of the solar system, looking at the asteroid belt there and mused, "Actually, the Kuiper Belt outside Neptune is also quite suitable. It is further away from the earth and there are very few planets there. The satellite passing there is very convenient for us to hide there and develop in secret."

"But it is indeed too far away from the earth and the sun. If something happens here on the earth, it will not be very convenient. In a real emergency, if it is delayed for one more minute, the consequences will be quite terrible."

After speaking, Dong Chen looked back at the asteroid belt between Mars and Jupiter, nodded and confirmed, "This is still the right place."

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

"You can attack if you advance, you can retreat..."

"Well, if something unexpected happens on Earth, the spacecraft we built can rush to Earth faster to provide support, and the concealment effect is basically not delayed. The number of artificial satellites visiting here is also small."

"If there are uninvited guests from outside the solar system, our spacecraft can respond immediately and even bring them an unexpected encounter on an asteroid."

"Absolutely perfect."

"Yes, sir," Number 1 also said beside him, "If we exclude it according to your requirements, only the asteroid belt located between Mars and Jupiter is suitable for your shipbuilding plan."

"Then don't worry about it," Dong Chen said firmly, "On the 1st, mark for me the positions of Ceres, Vesta, Pallas and Juno in the asteroid belt, and I'll take a look at their positions. Actual location and operational status.”

"Also, their size and composition are also marked. By the way, their holographic images should be enlarged appropriately, otherwise I can't see clearly."

"Okay sir, process the image for display."

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

There were originally bright edges indicating that there were four bright spots in the asteroid belt. The four bright spots quickly grew in size, and then they became the four largest planets in the asteroid belt that Dong Chen had an impression of.

These information 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 previous solar system. In the early development of human beings, the asteroid belt has been almost developed, so here The hologram of the solar system cannot be used as a reference for the Earth side.

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

"Vesta is one of the largest asteroids in the solar system. It has a metallic core mainly composed of iron and nickel, and is covered with a mantle mainly composed of olivine and a rocky crust. Its shape is affected by gravity and is an oblate spheroid. On average The diameter is about 525 kilometers."

"Pallas is the second asteroid discovered. Its composition is similar to that of carbonaceous chondrites. Its main components are silicates, oxides and sulfides. Its average diameter is about 520 kilometers."

"Juno is an S-type asteroid composed of heavier rocks. Its surface contains components of chondrite meteorites, as well as iron-containing silicon hydrochloric acid found in ordinary stony meteorites. It has a diameter of about 240 kilometers."

Looking at the actual data displayed on the 1st, and then looking at the orbits of the four "behemoths" in the asteroid belt, Dong Chen thought for a while and said, "There are no human man-made spacecrafts near these four planets. ?”

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

After showing the artificial satellite to Dong Chen, No. 1 said, "Currently there is only the American Dawn asteroid probe, but it has consumed all its fuel in the fall of 2018 and has lost its ability to work. .”

"That's good, I just observed their orbital status," Dong Chen said while looking at the four enlarged planets, "I plan to build an industrial zone on each of these four planets and divide them into four development bases, including Spacecraft manufacturing plants and material supply plants, as well as interstellar defense lines.”

"Their four planets are basically in four directions during their movement. Although they sometimes overlap due to the speed of movement, basically most of the time they can ensure that they are visible in all four directions."

"I feel that the danger of the Great Filter is not just a "natural" hazard in the galaxy. It is very likely that it will encounter a relatively strong alien civilization. If the civilization of this galaxy is destroyed by other galaxy civilizations, it should be considered a successful filter. "

"So we have to guard against this."

"Okay, sir, this information has been recorded. At that time, I will divide all the equipment into four parts and prepare for foundation construction." No. 1 said next to him.

Hearing this, Dong Chen nodded. After determining the issue of base construction, he then thought about the mining ships used to collect mineral deposits after the base was built, the military ships used for offense and defense, and the ships that might be used for escape in the future. The problem of colonial ships.

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

And the configuration of these things will definitely not be at the same level as those prepared by the Arc Light Group. If they are the same, then preparing this third insurance will be in vain.

The plans just announced by the Arclight Group seem to be many, but none of them involve the key interstellar immigration ships and interstellar battleships. They are basically focused on developing strength and exploring the solar system, so these three plans are not overlapping or conflicting.

What Dong Chen has prepared for himself is world-class technology for the ship-selling citizens, which are much more advanced than those on Earth.

If a civilization of Atlantis level or higher comes by then, Dong Chen has nothing to worry about. He can definitely fight back or even eliminate it.

But if what comes is a civilization that is more advanced than the world of ship-selling citizens, then Dong Chen has no choice.

After all, he has prepared the best, and if he can't beat him, it can only be considered a big filter.

Thinking of this, Dong Chen stopped looking at the hologram of the solar system. Instead, he looked at No. 1 and asked, "Industrial robots and parts from various factories are no problem. Regarding military ships and mining units, I remember that there are several ready-made ones here." The manufacturing plan is not, although it is a bit small."

Hearing this, No. 1 said: "Yes, sir, do you want to check it out?"
