In addition to studying the mysteries of the fortress of civilization, there is one more thing that needs to be weighed and considered as soon as possible.

This is how Celestial One should advance and retreat.

At present, Celestial One is in the process of replacing the latest nuclear fusion engine bay, which will take about 15 days.

It is now located 173 AU from the blue star, because it is below the ecliptic plane, and there are no decent asteroids or large meteorites around it.

This means that Celestial One's resources cannot be replenished on the spot, and all of them need to rely on the resources they brought with them when they left at the beginning.

However, due to the hurry of leaving, the resources carried were extremely limited, and even the variety was not comprehensive.

After the completion of the replacement of the new energy engine compartment, no further major construction projects can be carried out.

Although the Tours fleet has not forcibly entered the solar system at present, it does not mean that the other party is really incapable of breaking in.

Therefore, Celestial One must not be withdrawn.

Du Qiu's idea is to increase the development of the ninth planet and transport the resources on this planet to Celestial One.

Prior to this, Celestial Realm Two, which was flying towards Celestial One, carried plenty of various resources that could be used as supplies for the first phase.

Celestial 2 is based on the optimized design of Celestial 1, which not only adopts the latest nuclear fusion engine compartment, but also fully uses the latest new silicon-aluminum-titanium ternary alloy material to make the hull.

This material is far stronger than the previous silicon-aluminum alloy, which is a hull material that Du Qiu found through the ship's database when building the capital ship, which can be mass-produced.

On top of that, the use of this material for the hull has greatly increased the maximum speed of the warship due to the increased strength of the battleship, driven by the latest fusion engine.

For example, Celestial One, which only replaces the nuclear fusion engine, can only reach a maximum speed of 8,000 kilometers per second, but Celestial 2 can reach 15,000 kilometers per second.

Such a sturdy hull can fly at such a high speed and is not afraid of a large number of tiny meteorite collisions in space, and of course, it is more suitable for ultra-long-distance interstellar voyages.

Now the population of Celestial Realm II is also quite large, more than six million people, after all, the space fleet has recruited more than one million people, each with an average of four to five immediate family members, and the total number of family members has reached more than six million.

Compared with the previous 11 million Celestial One, it is nearly half less, so there are a lot more resources that can be carried in it.

Because Du Qiu was only familiar with the battleships of the dominant civilization in the dream realm, the dominant civilization was already at the peak of the sixth level, and he was about to step into the seventh-level civilization at any time, and his warships all had powerful space jumping capabilities.

When traveling over ultra-long distances, if you need resources, you can always find a star system to replenish resources through a few space jumps.

Therefore, when Du Qiu was learning to build a space fleet, he did not have a corresponding reference, so he ignored this part of the supporting measures.

The current level of scientific and technological development of the civilization of Magical Technology is extremely unbalanced, and if you have to measure it, it can barely be regarded as a third-level civilization.

But now the comprehensive level of the main warship built by Du Qiu is barely considered to be the fourth level, but it lacks the most important super-light speed flight ability, and the resource supply problem of ultra-long-distance interstellar navigation has become a big problem.

Therefore, the current magical technology fleet must be built with auxiliary warships, and the construction of large transport ships is on the agenda.

As for the design of the large transport ship, Du Qiu was not worried, and it was handed over to Hao Jian, the bald director of the battleship design institute.

Magical TechnologyToday's warships and ships have a significant generation difference, and if they are put together to sail away, there will be big problems.

For example, the maximum speed of the first batch of 20 frigates was 3,000 kilometers per second, and the maximum speed of Tianjie 1 was 8,000 kilometers per second after the new energy engine was improved.

But the maximum speed of Celestial 2 is 15,000 kilometers per second, the maximum speed of the capital ship is 18,000 kilometers per second, and the latest frigate has been raised to 20,000 kilometers per second.

As for the Pterodactyl fighters, the first generation produced 300,000 units with a maximum speed of 3,000 kilometers per second, and the second generation produced 200,000 units, with a maximum speed of an astonishing 30,000 kilometers per second, which has already reached one-tenth of the speed of light.

In this way, once the old and new generations of ships and warships are mixed and sailed, and this voyage is likely to be a flight, it will face a huge problem.

After discussion, the final plan was to build Celestial Realm 3 as soon as possible, and transfer the personnel and materials of Celestial Realm 1 to Celestial Realm 3.

As for the first-generation transport ships, frigates and Pterodactyl fighters, they have all shrunk to the Mars and Moon areas, and they are all included in the Blue Star Frigate Fleet as the last barrier to defend the Blue Star.

At present, the construction period of the Celestial-class spaceship basically only takes two months.

Lin Feng's Blue Star Escort Fleet's suppression and purge of Blue Star made the entire Blue Star very harmonious.

The Board of Directors unanimously decided that the first-generation fighters could be exchanged for those countries that performed well, and some of the technology of Celestial One could also be licensed for exchange.

In this way, on the one hand, some ready-made semi-finished resources will be recovered, and the company's current warship and fighter construction process will be accelerated, and on the other hand, the people on the Blue Star will also have a hope.

Before, Celestial Realm No. 1 retreated in a hurry, and there was no way to take people from any country, but it was really because of the suddenness of the incident and the urgency of time.

Now the Tours fleet does not know when to break into the solar system, so it is simply allowed to let the capable countries build their own manned spaceships, and in case the Tours fleet comes in, it is good to have more people.

The reason why Du Qiu dared to do this was because the fleet of magical technology had been renewed, and this generation gap would be further widened.

In this case, Magical Technology can lead the development of Bluestar Technology, and naturally it will not be swept away.

Du Qiu was still dissatisfied with the space battleships owned by Magic Technology now, believing that the overall level had not reached the middle of the fourth level.

First, it lacks the protective cover technology that a third-level civilization has, and secondly, it lacks the superluminal flight ability that a fourth-level civilization warship should have.

Of the two technologies, the shield technology is a little lower-end, or its threshold is lower, that is, it matches the level of civilization.

In the third-level civilization stage, there can be the electromagnetic shield technology of the third-level civilization, and when you enter the fourth-level civilization, there will be the energy shield technology that matches the fourth-level civilization.

As for the fifth level, there will be space shield technology, and the sixth level civilization will have dimensional shield technology.

Level 7 civilization is the multi-composite shield technology.

This is what Du Qiu learned from the ship's database recently, and he initially thought that the ship's capital ship shield was an energy shield.

After reading the database information, I realized that this is an energy shield combined with dimensional control.

It's a pity that the information here only has some basic principles, and there is no corresponding manufacturing technology, which makes Du Qiu very longing for the distant No. 11 base.

Of course, he was even more interested in the attack weapon of the Geya Civilization Mothership to burst the attack weapon that dominated the Civilization Mothership, and he knew that it was a space weapon.

Obviously, the Geya civilization has a special understanding of space, so that it can have a magical civilization fortress and such a powerful space weapon.

After Du Qiu held a board meeting with everyone, he immediately held a new meeting with the major research institutes to assign the key research topics in these two aspects.

Although Wittmann had already begun research on faster-than-light flight, according to the tradition of magical technology, the same subject would be divided into at least three research groups.

Du Qiu believes that under the same principle, after the research of the smart Blue Star people, there may be different ways to achieve it, and some surprises will occur.

This not only exercises the scientific research team of Miracle Technology, but also forms a benign competitive situation, so that every scientific researcher can give full play to his creativity.

As for the two more resources consumed by scientific researchers, in the interstellar era, it is just the mining and production of more intelligent robots.

This is the interstellar era, with a huge amount of cosmic resources!

Not to mention the various asteroid resources in the asteroid belt and the Kuiper belt, even the newly discovered ninth planet has all kinds of metal and non-metal resources that are not inferior to the blue star.
