Wittmann projected the photos taken by the astronomical telescope into the hall of the Mars Command through holographic projection.
"Boss, you see this is a previous photo. The highlight of this location is the white spot we have been paying attention to. The next photo is the latest one. Look at the same location."
Du Qiu listened to Wittmann's story and looked at the comparison of the two photos in front of him, and his heart gradually sank.
In the latest photo, where the white spot originally was, there is a larger bright spot, which is more than three times larger than before.
"Professor, does this mean that part of the enemy's fleet may not have started its engines before?"
Wittmann replied: "It's possible."
"Can't you be sure?" Du Qiu asked.
"The main reason is that this white spot has no signs of moving until now. I can't be sure that it is the tail flame of the space fleet."
Du Qiu frowned and said: "But in the middle of the two star systems, it is completely a dark void, and there is no possibility of any reflective material."
"If it weren't for the appearance of the meteorite battleship, I still wouldn't be able to regard this completely motionless white spot as the tail flame of the space fleet." Professor Wittmann expressed his doubts.
Du Qiu thought for a while and said, "Have you observed the situation around the white spot? Is it possible that the other party has a similar invisible warship?"
Wittmann said: "It cannot be ruled out that they will light up their tail flames at the white spot to complete their acceleration, then enter the inertial navigation state and turn on the stealth system, then we will indeed lose their traces.
But as I just said, this white spot has almost not moved at all..."
"No." Du Qiu interrupted, "Professor, the white spot is now more than three times larger than before. According to calculations, such a large white spot means that it actually covers at least tens of millions of kilometers.
Does this mean that the enemy warship turned off its engine and entered an inertial flight state after accelerating tens of millions of kilometers?"
Du Qiu is no longer a novice in astronomy as he was before, let alone a novice in interstellar warfare. After this period of time, he has continued to learn from the ship's previous battles, and at the same time continued to simulate invasion wars. For this upcoming counterattack, he has
I already have some confidence in dealing with it.
Wittmann was stunned for more than ten seconds. "Boss, what you said makes sense, but if the enemy fleet only accelerates a few tens of millions of kilometers, it will probably take more time to reach the solar system at the speed achieved."
Du Qiu became excited and said: "Yes, so now your task is to calculate the speed they will reach after accelerating tens of millions of kilometers based on 5,000 kilometers per second.
Within a certain area, focus on monitoring and observation to see when new white spots appear, then you will have found traces of the enemy."
"The boss's idea is very good. I will start arranging people to monitor the area in different areas and never let the enemy fleet escape our sight."
Du Qiu ended the call with Wittmann, feeling that something was wrong.
I just thought about it carefully and didn't think of anything.
However, Du Qiu still made a prudent move and arranged for Stardust to increase the production and deployment of detectors.
He wants to spread these tentacles that can monitor and perceive battlefield situations throughout the solar system, and if there is time, even extend to several major directions outside the solar system.
After arranging this matter, Du Qiu began to devote all his energy to the development, production and deployment of new weapons. This weapon can be called the killer weapon of magical technology.
This was also Du Qiu's confidence to face the invading fleet.
Time flies by, and three months have passed in the blink of an eye.
Various detectors are being deployed more and more everywhere in the solar system, monitoring every void in the solar system.
Not only that, some detectors have already extended outside the solar system.
It is also for this reason that the Celestial Spacecraft, which has already entered the safe escape zone in interstellar space beyond the Kuiper Belt, can still maintain communication with the Mars base.
The celestial spacecraft flies directly outward at a certain angle to the ecliptic plane of the solar system. This kind of space flight cannot rely on the gravity of the major planets in the solar system.
This type of flight requires huge energy support. Using the metallic hydrogen energy carried by the Tianjie spacecraft, the endurance is about 200 years.
In other words, the energy carried by the celestial spacecraft cannot fly to nearby star systems.
Therefore, the celestial spacecraft needs to continuously collect hydrogen elements in the void before leaving the Oort cloud range.
After all, in the real interstellar space between galaxies, there is not as much hydrogen element as there is in the Oort cloud.
However, Du Qiu has handed over the latest nuclear fusion engine system technology to the research institute. In the past three months, the Tianjie spacecraft has completed corresponding production. At this moment, the Tianjie spacecraft is preparing to replace the main engine module.
With this new type of nuclear fusion engine, which uses no working substance radiation energy to obtain powerful propulsion speed, the speed of the Tianjie spacecraft will be increased from the original 3,000 kilometers per second to 8,000 kilometers per second.
Taking this opportunity, Ning Shuangshuang was having a holographic video call with Du Qiu.
"You mean, we haven't found any trace of the invading enemy yet?" Ning Shuangshuang couldn't hide her inner shock.
Du Qiu nodded and said: "Yes, it's as if they never existed. Our current detection capabilities outside the solar system are still very insufficient, and we can only monitor a few key directions.
However, in the past three months, no findings have been found in these key directions. After the white spot suddenly grew larger two months ago, it did not take long to return to its original state.
My inference is that the enemy moved out from there, and after accelerating, it shut down the engine and entered an inertial flight state."
"Are we completely unable to detect space battleships in inertial flight in the interstellar void?" Ning Shuangshuang asked.
"This is still somewhat difficult. If it is a massive object, our gravitational wave detectors can detect some anomalies. However, the space fleet is not a massive object. At present, our gravitational wave detectors are not yet so sensitive.
"
Du Qiu also had some headaches. The quantum radar, which was copied from the Dreamland alien civilization, did not know if some of the material parameters did not meet the standards. The detection range simply could not reach the level of similar equipment on the Dreamland alien civilization's capital ship.
The equipment on the capital ship of the alien civilization in Dreamland has a detection range of an astonishing 5 light years.
At present, the one copied by Du Qiu only reaches 10 astronomical units, and it is still equipped on battleships.
The detection range equipped on the Wing Loong fighter is only 2 astronomical units.
Therefore, although the patrol formation of Wing Loong fighters sent by Du Qiu has reached a position as far as 300 astronomical units from Blue Star, it is still out of reach of White Spot.
Of course, there is another possibility. The other party is flying at super-light speed, that is, in a moving curvature bubble, which magical technology is unable to detect.
However, if this is the case, they should have reached the solar system and should be separated from this state. After all, Du Qiu knew that the fleet in the initial super-light flight state would not be able to fly at super-light speed within the star system.
However, around the solar system, the detection network found nothing at all.
"Du Qiu, could it be that our judgment was completely wrong? The meteorite battleship did not come from that white spot, but may have come from a more distant place."
Ning Shuangshuang hesitated and finally expressed his inner thoughts.
A fleet preparing to invade the solar system stayed 3 light years outside the solar system, waiting for the meteorite battleship to investigate the solar system.
Then what will they do after discovering that they have lost contact with the meteorite battleship?
Listening to Ning Shuangshuang's words, Du Qiu thought, his mind quickly going through the simulation process of this war in the ship's simulation environment.
Ning Shuangshuang was right to remind him. He had always assumed that the invasion fleet was at Bai Ban's place. What if the invasion fleet was in another direction?
Previously, magical technology had not been able to detect and monitor all aspects of the solar system. Even if there were traces of an invasion fleet sailing in a certain direction, it would be difficult to catch it.
If it weren't for the fact that the Oumuamua meteorite looked too much like a man-made object, I wouldn't have ordered a Pterosaur fighter plane to capture it.
At the same time, Wittmann and his colleagues would not detect the direction in which the Oumuamua meteorite left, thereby discovering abnormal white spots.
However, we did not detect the direction in which the Oumuamua meteorite came. What if the enemy was divided into two groups at the beginning?
When he thought this, Du Qiu broke into a cold sweat.
