For a technological civilization in the middle of level-5, their understanding of space technology was only at the beginning.
Not to mention that only a Level 6 civilization possessed space attack methods, which they could not understand at all!
However, even if they did not understand, Black Fiend clearly knew that he was being attacked. It was just that he could not understand the other party's attack method at all.
It would be fine if he could not understand the method, but the key was that he did not even know where the other party was.
At this moment, a very absurd thought flashed through Black Fiend's mind!
Would the enemy launch an attack at him from a distance away?
As far as the current detection technology of the Ziyun Empire was concerned, it could be divided into close-range, mid-range, and long-range detection.
Among them, close-range and mid-range detection were the most used. As for long-range detection, it was generally not used unless it was under special circumstances.
This had a lot to do with energy consumption. If the maximum range detection was used continuously, the energy consumption would be quite terrifying.
Basically, for every additional 1AU of scanning distance, the energy consumption would increase exponentially.
After all, a mid-level Level 5 technological civilization's detection technology had not yet involved the in-depth application of space technology. Whether it was distance or energy consumption, it was not ideal.
"Activate long-range detection immediately and find the enemy!"
"General, what is the scanning distance?"
"Set the maximum value at 20AU!"
"Yes!"
At the same time, the adjutant took in a deep breath of cold air.
Could it be that Black Fiend General suspected that the enemy was at a distance of more than ten or even 20AU?
How was this possible?
The adjutant racked his brains but still could not figure out what kind of weapon could attack from such a long distance!
However, looking at the tactical image, the targets on his side were constantly disappearing, and the scene outside the ship where there were no signs of attack but the battleships were constantly being pierced through.
The adjutant swallowed his saliva and immediately executed Black Fiend's order!
No way, there really was?
A minute later, standing behind Suo, the adjutant's eyes widened when he saw the results of the detection. He was stunned for a moment!
"General … General … Suspicious targets have been found at a distance of 10AU. There are about 10 million battleships, but there are no signs of these targets firing!"
"10AU? Whether it is them or not, immediately send one, no, two battleship formations to control them. If there is any resistance, destroy them on the spot! "
"Yes!"
Originally, the Black Fiend had planned to send a fleet (according to the Ziyun Empire's organization, a fleet of battleships was 100 million battleships). However, when he thought of the enemy's strange and terrifying attack, he immediately changed his order and sent out two fleets!
From Hei Sha's point of view, no matter how powerful the other party was, it did not seem like they were from a level-6 civilization. The greatest possibility was that they had developed some kind of special weapon.
Thus, 200 million warships should be more than enough to annihilate 100 million warships.
However, reality soon poured a bucket of cold water on him!
"Dark Demon General, Third and Fourth Squads are reporting that they are unable to perform the warp jump. They are suspected to have encountered interference from the warp jump blocking device!"
At this moment, the adjutant suddenly turned to Hei Sha and shouted anxiously.
How could he not be anxious?
He couldn't fight back, and the suspected enemy's fleet was 10 AU away. Now, he was told that he couldn't warp due to the interference of the warp blocking device.
What did it mean to be unable to warp?
This meant that he had no way of getting close to the enemy's fleet!
Approaching at sub-light speed?
Let's not talk about whether or not the other party would cooperate with you and move in the opposite direction to maintain a distance!
Even if the other party did not run away and allowed you to approach, the adjutant doubted that his one billion warships could complete half of the journey!
"How is this possible?"
"In the entire galaxy, only the Purple Cloud Empire has the technology to manufacture the warp jump blocking device. We have never leaked this kind of equipment or technology!"
"It can't be that a level-5 civilization was born on the front spiral arm, right?"
Alright, what Hei Sha did not know was that there was indeed no level-5 civilization on the front spiral arm. However, a level-6 civilization had come from another galaxy!
"General, what should we do now?"
"..."
Hei Sha was silent. This was a good question.
What should they do?
Of course, they had to retreat!
What a joke. They knew that they had no way of attacking the other party. Why would they continue to stay here and be a target for the other party?
However, they had to leave some gifts behind before retreating!
"Release all the strategic reconnaissance ships immediately. After that, order the entire fleet to retreat to the rear spiral arm immediately!"
"Yes, General!"
Soon, dozens of small strategic reconnaissance ships flew out from Hei Sha's flagship and quickly headed toward the location of the target.
Speaking of the strategic reconnaissance ships of the Purple Cloud Empire, in fact, they were similar to the strategic reconnaissance ships of the Citria Empire, one of the four giants of the Milky Way.
This was a type of ship that was specially developed for detection technology. It could effectively block all wavelengths of scanning and was also equipped with stealth camouflage technology. Thus, regardless of detection or vision, it could achieve the effect of full stealth.
Even a level-5 civilization would find it difficult to detect these reconnaissance ships.
Of course, this had no effect on the space radar of a level-6 civilization!
"Commander, we have discovered that the other party has released more than 20 small reconnaissance ships. They should be a type of stealth reconnaissance ship!"
"Yes, mark these reconnaissance ships. Also, mark them as not to be attacked!"
"Yes, Commander!"
After Hei Sha released the strategic reconnaissance ships, they were immediately captured by the Pangu Ship. In front of the space radar, these so-called stealth reconnaissance ships were as conspicuous as if they were naked.
However, all of this was under Lin Yu's command. Hei Sha had no idea.
Seeing that the deployed strategic reconnaissance ships did not suffer any attacks, Hei Sha's anxious heart seemed to relax a lot!
"Order the fleet to enter the wormhole immediately and retreat to the rear spiral arm!"
"Yes, General Hei Sha!"
On the other side, the retreat of the Purple Cloud Empire's tribute fleet naturally could not escape the detection of Lin Yu's fleet.
"Commander, the enemy has begun to retreat toward the wormhole. Should we have the fleet use Spatial Tear to attack?"
Speaking of which, from the start of the battle until now, under Lin Yu's orders, the fleet had been using a type of attack called Spatial Pierce.
Although this attack was powerful, it was only a single point attack and did not have the effect of causing damage over a large area.
Thus, although the Purple Cloud Empire was unable to retaliate, it did not cause enough damage to cause the fleet to collapse.
After all, Lin Yu's goal was not to completely destroy the enemy's fleet, but to lure the enemy into his ambush so that the Neutron Warstar would come crashing in.
"No, there's no need. Continue to maintain the current attack method until the enemy has all retreated into the wormhole!"
"Yes, Commander!"
