The moon is now an important fulcrum of the star-moon defense line.
Miraculous Technology has built six defensive fortress areas here. Except for the first and second defensive fortress areas, which were electromagnetic railguns built earlier, the four subsequently completed are all special material cannons.
Because it's on a planet, you don't have to worry about not being able to place it. The length of the special material fortress cannon here reaches an astonishing 10,000 meters. It's really a 10,000-meter giant cannon.
This huge gun barrel has a diameter of 1,000 meters, half of the entire gun body stands above the ground, and the remaining half of the gun body is hidden underground.
The entire cannon is surrounded by a movable alloy floor. When the pitch angle of the cannon needs to be adjusted, the alloy floor will open, revealing a huge open hole.
Overall, these four special material cannon fortresses can basically block the attack route to Blue Star from the direction outside the solar system.
Fortunately, when this special substance is fired, it does not have the recoil and destructive power of gunpowder cannons.
Because there is a magnetic field generating coil outside the gun barrel, the special material is ejected under the constraints and acceleration of the gun barrel's magnetic field and will not harm the gun barrel.
Du Qiu has not yet figured out what this special substance is. He can only create its generator and connect it to the magnetic field accelerating gun barrel.
Once the war starts, the generator can be activated to produce special substances, which are then sent into the barrel to be accelerated and launched.
This substance is currently being analyzed by the Institute of Physics. Du Qiu believes that once it is analyzed, a unified theory may be able to be solved.
Defense Fortress Area No. 1.
A planetary bus landed lightly at the fortress and exited the landing zone.
Zheng Song, the commander of the Lunar Defense Fortress, quickly greeted him. What came off the planet bus was Du Qiu, who was wearing an aerospace battle suit, and a group of accompanying personnel.
There are not many humans in the Lunar Defense Fortress. Most of them are intelligent robot soldiers. All human soldiers stationed here are prepared to sacrifice.
"Boss, everything is ready."
"Well, things went well. Come on over."
Regarding the lunar area mentioned in the second message of the Tour fleet, Magic Technology conducted in-depth excavation and exploration for half a year, and finally made a discovery more than a thousand kilometers deep into the underground of the moon.
This is already equivalent to the center of the moon.
Not only that, with the detection of Pleiadian information shielding equipment, the research team led by Ding Shaoqiu has discovered relevant equipment burial sites on the rocky satellites of all major terrestrial or gaseous planets in the solar system.
However, this time the research team did not move the equipment loaded with these cubes after completing the excavation.
After all, outside the solar system, there is a level 4 civilization fleet watching with eager eyes at this moment.
What if these information shielding devices also serve as that magical fortress of civilization, and if they are moved and the fortress function disappears, that would be a big deal.
Nowadays, Miracle Technology has taken every means to increase production, increasing production capacity ten times compared to the initial level, but the number of capital ships has only just reached 2,000.
According to Rhine Soko's previous estimate, he could just rely on the fortress defense system to withstand the attack of the Tour fleet.
It's just that this is based on the little information we have learned before. If the technological level of joining the Tour fleet is higher than expected, or there are some unknown killer weapons, it may still be unable to block the opponent's offensive.
Therefore, it is crucial to maintain the defensive capabilities of the fortress of civilization.
Du Qiu has already suspected that there may be a similar arrangement in the meteorite belt at the edge of the distant Oort cloud, and the linkage communication between these devices should be quantum communication, otherwise real-time total control on the moon cannot be achieved.
Although Du Qiu has already obtained quantum communication technology from his dream, there is a big gap in the realization of related hardware products.
For example, some key component materials of communication equipment, the composition and production process of these materials are not available in the fourth-level civilization production database previously obtained from the maintainers.
Now Du Qiu has an understanding of the artificial intelligence system that dominates civilization, and knows that the production materials higher than the fourth-level civilization are stored in the sixth-level intelligent creators.
The Intelligent Maker can only be obtained by going to the Base Galaxy No. 11.
Speaking of this matter, Du Qiu was very helpless, because he could no longer complete his previous plan to withdraw from the base 11 galaxy.
Originally, Du Qiu controlled half of the second-level fleet. After a year of super-light flight, he should have returned to Base 11.
Everything went smoothly at first, but when it got close to 300 light years away from Base 11, it was intercepted by the Geya civilization fleet.
This forced Du Qiu to continuously command the fleet to fight with it, then quickly escape, and then make a detour to move towards Base 11 again. As a result, he soon encountered the Geya civilization fleet again.
In each battle, the fleet lost several capital ships.
Now, more than a year later, the remaining second-level fleet controlled by Du Qiu in his dream has still not been able to return to Base 11.
However, after many battles with the Geya civilization interception fleet, Du Qiu finally discovered the problems contained therein.
He determined that this half of the fleet would definitely not be able to return to Base 11, because he found that his fleet always entered a position 300 light years away from Base 11 and was intercepted by the Geya fleet.
A more vivid description is that every time the half of the fleet led by Du Qiu ran into this line of defense, they hurriedly fled and evacuated, then changed their routes and approached again 300 light years away, when they bumped into the Geya fleet's line of defense again.
.
Obviously, the Geya fleet has completely surrounded the No. 11 base system and formed a blocking defense line 300 light years away from the No. 11 base system to prevent any fleet from reinforcing the No. 11 base system.
At first Du Qiu thought that the Geya fleet was searching and intercepting his half of the fleet, but later he discovered that he was simply trying to sneak into their defense network, and of course he would run into it.
As a result, Du Qiu felt a little depressed. His plan to return to Base 11, infiltrate and control the Intelligent Makers was disrupted by the offensive actions of Geya Civilization.
In these several battles with the Geya fleet, the fleet has lost 40 capital ships, leaving only 316 ships.
Moreover, in the recent encounters with the Geya fleet, the opponent's warships have exceeded our own in number. Obviously, the route chosen now may have encountered the opponent's main force.
If he had to force his way through, the whole army would definitely be annihilated.
Therefore, Du Qiu has turned the fleet away, 50 light years away, and temporarily hid in a star system.
Du Qiu speculated that the Geya civilization was launching an offensive operation against Base 11 in Area 220, which dominated the civilization. The fleet had been attacked by the Geya civilization fleet on its way back after collecting resources, which may have been the prelude to this battle.
Du Qiu controlled this half of the fleet to conduct several encounters with the Geya civilization, which gave him a good training in actual combat and gained a more practical and profound understanding of the interstellar war between level six civilizations.
Therefore, he simply hid and waited for the outcome of the battle between the dominant civilization forces and the Geya civilization.
Du Qiu still wanted to see this unprecedented battle between two level six civilizations with his own eyes.
Du Qiu learned from the ship's database that the Geya civilization should have come to an end. Perhaps this battle was the final elegy?
Of course, this is one-sided information in the ship operator's database, and it may not be accurate. If the Geya civilization is really coming to an end, it will be too late to preserve its strength and run away. How could such a major counterattack be carried out? Isn't this a loss of life?
However, Du Qiu intends to be a real melon-eater and at most see if he can find a way to get some battleship wreckage of the Geya civilization.
Several battles with the Geya Civilization made him covet the space weapons of the Geya Civilization, as well as a throwing bomb of the Geya Civilization, which was far more powerful than Du Qiu's knowledge.
In several battles, two-thirds of Du Qiu's battleship losses were caused by these two weapons.
