The moon is now an important fulcrum of the Xingyue defense line.

Magical Technology has built six defensive fortified areas here, except for the first and second defensive fortified areas, which are electromagnetic railguns built earlier, and the four subsequent completed ones are all special material cannons.

Because it's on a planet, don't worry about not being able to put it down, the length of the special material fortress cannon here reaches an astonishing 10,000 meters, which is really a 10,000-meter cannon.

The diameter of this huge barrel is 1,000 meters, and half of the entire barrel stands above the surface, while the remaining half is hidden underground.

The entire cannon perimeter is a movable alloy floor, which opens up when the pitch angle of the cannon needs to be adjusted, revealing a large open hole.

Overall, the fortress of these four Special Matter Cannons can basically block the attack route against Blue Star from outside the solar system.

Fortunately, this special substance does not have the recoil and destructive power of a gunpowder cannon when fired.

Because there is a magnetic field outside the barrel of the cannon that generates a coil, the special substance is restrained and accelerated by the magnetic field of the cannon barrel and flies out without harming the barrel.

At present, Du Qiu has not yet figured out what this special substance is, but he is able to build its generator and connect it to the magnetic field acceleration barrel.

Once the battle starts, the generator can be activated to produce a special substance, which is sent into the barrel of the gun to accelerate and fired.

This kind of substance is currently being analyzed by the Institute of Physics, and Du Qiu believes that once it is analyzed, perhaps the unified theory will be able to get through.

Fortified area No. 1.

A planetary bus lands lightly in and out of the fortress landing zone.

Zheng Song, the commander of the lunar defense fortress, hurriedly greeted him, and getting off the planetary bus was Du Qiu, who was wearing an astronaut combat suit, and a group of entourage.

There are not many humans in the lunar defense fortress, most of them are intelligent robot soldiers, and all the human soldiers stationed here are ready to sacrifice.

"Boss, everything is ready."

"Well, things are doing well, let's get over quickly."

In response to the lunar region mentioned in the second message of the Tours fleet, Mirage Technology has carried out deep excavation and exploration for half a year, and finally made a discovery more than 1,000 kilometers deep into the moon.

This is already the equivalent of the center of the moon.

Not only that, with the detection of the information shielding equipment of the Pleiades, the research team led by Ding Shaoqiu has found relevant equipment burial sites on the rocky satellites of various terrestrial planets or gaseous planets in the solar system.

However, this time, after completing the excavation, the research team did not move the equipment loaded with these cubes.

After all, outside the solar system, there is a fourth-level civilization fleet eyeing it at this moment.

In case these information shielding devices also function as a magical fortress of civilization at the same time, and the fortress function disappears after moving them, it will be a big deal.

Now, Magic Technology has taken all means to increase production, so that the production capacity has increased tenfold compared with the beginning, but the number of capital ships has just reached 2,000.

According to Rheinsocko's previous estimates, it was just able to rely on the fortress defense system to resist the attack of the Tours fleet.

It's just that this is based on the little information that I know before, and joining the Tours fleet is a little higher than the estimated level of technology, or there are some killer weapons that I don't know, maybe I still can't stop the opponent's attack.

Therefore, it is crucial to maintain the defensive capability of the fortress of civilization.

Du Qiu already suspects that there may be a similar arrangement in the meteorite belt in the remote Oort cloud edge area, and the linkage communication between these devices should be quantum communication, otherwise it is impossible to achieve real-time total control on the moon.

Although Du Qiu has already obtained the technology of quantum communication from the dream, there is a big gap in the realization of related hardware products.

For example, some key components and materials of communication equipment, the composition and production process of these materials are not available in the fourth-level civilization production database obtained from the maintainers.

Now that Du Qiu has an understanding of the artificial intelligence system that dominates civilization, he knows that the means of production above the fourth-level civilization are stored in the sixth-level intelligent creator.

The Creator can only be obtained by going to Base 11.

Speaking of this, Du Qiu was very helpless, because he could no longer complete the previous plan to withdraw the No. 11 base system.

Originally, Du Qiu controlled this half of the second-level fleet, and as long as he flew faster than light for a year, he should return to Base 11.

At first, it went well, but when it approached 300 light-years from Base 11, it was intercepted by the Guya Civilization fleet.

This forced Du Qiu to command the fleet to fight against it, then quickly flee, and then make a detour to Base 11 again, only to be soon confronted by the Guya Civilization.

Again and again, the fleet lost several capital ships.

Up to now, more than a year later, the remnants of the second-tier fleet controlled by Du Qiu in the dream realm have still not been able to return to Base 11.

However, after many battles with the Geya Civilization Interception Fleet, Du Qiu finally discovered the hidden problems.

He decided that this half of the fleet would not return to Base 11, because he found that his fleet was intercepted by the Gya fleet every time it entered a position 300 light-years away from Base 11.

The figurative description is that every time the half of the fleet led by Du Qiu ran into this line of defense, it fled and evacuated in a hurry, and then changed the route and approached 300 light years again, and then ran into the defense line of the Geya fleet again.

Obviously, the Geya fleet has completely surrounded the Base 11 system and formed a blocking line 300 light-years away from the Base 11 system, preventing any fleet from reinforcing the Base 11 system.

At first, Du Qiu thought that the Geya fleet was searching for and intercepting his own half of the fleet, but later he realized that he was simply drilling into other people's defense nets, and of course he would collide.

As a result, Du Qiu was a little depressed, and his plan to return to Base 11 to infiltrate and control the Wise Creator was disrupted by the offensive actions of the Geya civilization.

These three times with the Geya fleet has been clashed, the fleet has lost 40 capital ships, only 316 remaining.

Moreover, in the last few encounters with the Geya fleet, the number of warships of the opposing side has exceeded that of the other side, and it is obvious that the route chosen now may encounter the main force of the opponent.

If you break through, you will definitely end up with the annihilation of the whole army.

So Ducho has turned the fleet, 50 light-years away, temporarily hiding in a star system.

Du Qiu speculated that the Geya civilization was launching an offensive operation against the No. 11 base in Sector 220, which dominated the civilization, and that the raid by the Geya civilization fleet on the way back after the fleet collected resources may have kicked off this battle.

Du Qiu manipulated this half of the fleet to have several encounters with the Geya civilization, allowing him to practice well in actual combat and have a more practical and profound understanding of the interstellar war between the sixth-level civilizations.

Therefore, he simply hid and waited for the outcome of this battle between the main army of the civilization and the Geya civilization.

In this great battle between the two sixth-level civilizations, Du Qiu still wanted to see it with his own eyes.

Du Qiu learned from the database of the shipwrecks that the Geya civilization should have come to an end, and perhaps this battle is the final elegy?

Of course, this is one-sided information in the ship's database, and it may not be accurate, if the Geya civilization is really coming to an end, it is too late to save its strength, how can it carry out such a big counteroffensive, isn't this a head-off?

However, Du Qiu intends to be a real melon-eating crowd, at most to see if he can find a way to get some of the wreckage of the battleships of the Geya civilization.

After fighting with the Geya civilization a few times, he coveted the space weapons of the Geya civilization very much, and there was also a kind of throwing bomb of the Geya civilization, which was far more powerful than Du Qiu realized.

In several encounters, two-thirds of the warships lost by Duqiu were caused by these two weapons.
