Next to Du Qiu is the holographic projection of Song Yuanting, commander of the First Fleet.
"Boss, this red dot is the position where our Wing Loong II fighter received the second radio wave. Based on this position, the second radio wave of the Tour fleet should be less than three years old."
Song Yuanting reasoned this way because the Pterosaur II formation gradually flew outward to expand the search and patrol range.
This message has not been received before, indicating that this electromagnetic wave has just spread here.
This is not like the first radio wave received half a year ago. In fact, after subsequent searches and comparisons, it was found that this radio wave even had partial echoes on the Blue Star.
In other words, the first radio wave has been introduced into the solar system a long time ago, and is continuously reflected and amplified by various planets or asteroids in the solar system, and thus spreads throughout the solar system.
It has been ignored because it resembles natural radio waves, so it has not been analyzed by anyone.
"So, there is a high probability that the Tour fleet is near the white spot. Our observation and inference about the white spot should be correct."
Du Qiu said and asked Xingchen to report the contents of the message.
Stardust immediately said: "The message is as follows: Dear civilizations in the Geya Civilization Fortress, if you can receive and interpret this message, please be sure to carry forward the spirit of alliance mutual assistance, open the civilization fortress, and come to rescue us.
The message we sent before stated that we carried out reckless detection activities, and we got some feedback information, knowing that your civilization is still at the first-level civilization stage.
Maybe you don't have the ability to open the Civilization Fortress, so please follow our instructions and you can open the Civilization Fortress.
Our warships can no longer support navigation beyond 3 light years, and we urgently need your assistance.
We can help you improve the development of your civilization. This is the mutual assistance clause of the Geya Alliance. Please believe that we do not have any ill intentions and we are allies.
The Geya Alliance is an alliance of all intelligent life in the galaxy. I believe you should know about the Geya civilization. They are the leaders of the alliance and have protected many weak civilizations with civilizational fortresses.
Our common enemy is the destroyer-dominated civilization of the universe. They are artificial intelligence civilizations and the mortal enemies of natural intelligent life.
Finally, please feel free to open the fortress of civilization. As allies, we look forward to your rescue."
After listening to Xingchen's translation, Song Yuanting smiled, "Do you think the Tour civilization is stupid? Since they know that we are so weak, how dare they open the fortress of civilization according to the methods they teach after hearing that they are far stronger than us?
"
Du Qiu was deep in thought and did not speak immediately.
After a long while, he asked: "Stardust, the method given by the Tour Fleet to open the civilization fortress, how exactly does it work? Can it really be completed according to the original technological capabilities of Blue Star?"
"Sir, the way to open the fortress of civilization is this. Use nuclear bombs with a total equivalent of one billion tons to completely blow up this area of the moon. Then the fortress of civilization can be opened."
Stardust answered and projected an image of the moon again, marking the area.
When Du Qiu saw that, he thought to himself "Sure enough".
The marked area is exactly the magnetic field anomaly area originally discovered, which is the area with huge vanadium-titanium magnetite deposits.
It has been completely protected by Du Qiu and is now surrounded by lunar defense fortresses.
"Hey, isn't this the center of our lunar defense fortress? Could it be that the meteorite battleship of the Tour fleet has detected the fortress we built, so it wants us to destroy it ourselves?"
Song Yuanting had clearly seen where Xingchen was talking and blurted out immediately.
Du Qiu sneered: "The Tour fleet wants us to abolish our martial arts. We should not use such violent means to open the fortress of civilization.
Even if there is really a close connection with the civilization fortress, but directly destroying it with nuclear bombs, doesn't it mean that the civilization fortress can no longer function?
Doesn't this allow the Tur fleet to enter and exit the solar system at will? Even if they don't destroy us, they can still enslave us."
Song Yuanting agreed: "Yes, I think that maybe deep underground in that place, there is a control room for the fortress of civilization. The Tour fleet asked us to destroy it with nuclear bombs. I am afraid that we will directly destroy the control room and make the fortress of civilization disappear."
Du Qiu had already agreed with Song Yuanting's statement. The previous detection range of the supermagnetic imaging instrument had been interfered with in some way, and it had never been able to detect the area below 5,000 meters on the lunar surface.
Later, a series of things happened, which caused Du Qiu to stop exploring there. Now it seems that further understanding is needed.
Maybe, as Song Yuanting said, there is a control room underground there?
Unexpectedly, the moon really hides a big secret.
"What you said makes sense. I will arrange to explore there as soon as possible."
"Boss, should we continue to ignore this message?"
Du Qiu nodded and said: "Yes, there is no need to pay attention to it. Didn't they say that they can no longer support a flight of more than 3 light years?
If this is not a lie, perhaps their warships are no longer able to fly at faster than light speeds.
Judging from the time when the second message was sent, they have been wandering around White Spot for nearly three years.
At the same time, the meteorite spacecraft can communicate with them. It seems that they should receive a report from the meteorite spacecraft when we destroyed the meteorite spacecraft 9 months ago.
Even earlier when we were building space cities, the scene on Mars would be detected by the meteorite spacecraft and sent back to the Tour fleet.
Calculating this, it will take more than two years for the Tour fleet to receive the information, and at that time some kind of coercive measures may be taken."
Song Yuanting said: "Boss, your calculation should be correct. After the Tour fleet receives this information, it will find that the Blue Star civilization is developing very fast, and has entered the second level, or even the third level civilization from the first level civilization.
They will be so scared that they will either violently break the fortress of civilization, or they will find a way to send meteorite warships into the solar system and destroy the moon!"
Du Qiu pondered: "Yes, if this control room is really hidden on the moon, they may indeed send warships disguised as meteorites, sneak into the solar system, and destroy the moon themselves.
It is unclear now what kind of warships the Tour fleet can send to sneak in, or what kind of warships the Civilized Fortress can block."
Song Yuanting said: "I guess the protection of the Civilized Fortress is still very strong, otherwise the Tour fleet would have broken in long ago.
Judging from the size and shape of the meteorite battleship, this meteorite camouflage should be the key to deceiving the civilizational fortress barrier.
In other words, the function of the civilized fortress is to block all unnatural flying objects and radio waves.
In this way, the warships they send in cannot be too big, otherwise they will not conform to the natural phenomenon of meteorites.
If it is still the size of a meteorite battleship, even if thousands of them are sent in, we are not afraid now, I guarantee that they will not enter the Kuiper Belt."
"No matter what, your First Fleet must step up patrols outside the Kuiper Belt. The ninth planet's defense system has entered level one combat readiness to attack invaders at any time."
"Yes, boss."
Seeing Song Yuanting's projection disappear, Du Qiu was not worried that Song Yuanting could not stop him. The First Fleet now has 300 battleships and 300 frigates.
All are second-generation warships, with high speed and preliminary electromagnetic shields.
That's right, after half a year of research, although there was no progress in the energy shield, it was successful in the electromagnetic shield.
This is because Du Qiu got inspiration from the magnetic field generator of the material purification equipment, which can create a strong closed magnetic field around the battleship.
Once this magnetic field is turned on, it can completely envelop the warship, and when there is an external physical attack, it can delay and detonate.
This kind of electromagnetic shield is the shield commonly used by Level 3 civilizations. The weapons of Level 3 civilizations are usually electromagnetic gun weapons, which fire some kind of high-explosive alloy warheads.
The electromagnetic shield is the nemesis of this alloy warhead, and can easily block the detonation.
