For a technological civilization in the middle of the fifth level, its understanding of space technology has only just begun.
Not to mention the space attack methods that are only available to level six civilizations, they simply can’t understand them!
However, even if he didn't understand, Heisha clearly knew that he was being attacked, but he just couldn't understand the opponent's attack method at all.
It would be okay if you just couldn't understand the method, but the key point is that you don't even know where the other party is.
At this moment, a very ridiculous idea flashed through Heisha's mind!
Will the enemy attack you from a few AU away?
As far as the current detection technology of Ziyun Empire is concerned, it can be divided into short-range, medium-range and long-range detection.
Among them, short-range and medium-range scanning detection are the most commonly used. As for long-range detection, they are generally not used unless under special circumstances.
This has a lot to do with energy consumption. If the maximum distance detection is enabled without interruption, the energy consumption is also quite terrifying.
Basically, every time the scanning distance increases by 1 AU, its energy consumption increases exponentially.
After all, the detection technology of mid-level five scientific and technological civilization has not yet involved the in-depth application of space technology, and both distance and energy consumption are far from ideal.
"Start long-range detection immediately and find the enemy!"
"General, what is the scanning distance setting?"
"Come on the maximum value of 20AU!"
"yes!"
While responding, the adjutant also took a deep breath.
Could it be that General Heisha suspected that the enemy was ten or even twenty AU away?
How can this be?
The adjutant thought hard, but he couldn't figure out what kind of weapon could attack at such a long distance!
However, looking at the disappearing targets in the tactical image, and the scenes outside the ship that clearly showed no signs of attack, but the warships were being penetrated one after another.
The adjutant also swallowed his saliva and immediately followed Heisha's order!
No, is there really one?
A minute later, standing behind the enemy officer, the adjutant stared at the results of the detection with his eyes wide open. He was a little confused for a moment!
"Admiral... found suspicious targets at a distance of 10 AU. The number is about 10 million warships, but no trace of firing was detected on these targets!"
"10 AU? Whether it's them or not, immediately send out one, no, two battleship formations to control them, and annihilate them on the spot if they resist!"
"yes!"
Originally Heisha was going to send a formation (according to the Ziyun Empire's establishment, a battleship formation is 100 million battleships), but after thinking that the enemy had such a weird and terrifying attack, he immediately changed the order and sent two
formation!
In Black Shark's view, no matter how powerful the opponent is, it is not necessarily a level six civilization, and the most likely possibility is that it has developed some kind of special weapon.
Therefore, it should be more than enough for 200 million warships to annihilate 100 million warships.
However, reality quickly poured cold water on him!
"General Heisha, the third and fourth formations reported that they were unable to make the jump. It is suspected that they encountered interference from the jump blocking device!"
At this moment, the adjutant suddenly turned around and shouted to Heisha with an anxious look on his face.
Can this not be urgent?
If you are beaten here, you can't fight back, but the suspected enemy fleet is 10AU away, and now you are told that it has encountered interference from the jump blocking device and cannot jump.
What does it mean to be unable to jump?
It means that you can't get close to the opponent's fleet at all!
Approaching at sub-light speed?
Let’s not talk about whether they will cooperate with you in moving in the opposite direction to keep distance!
And even if they don't run away and let you get close, the adjutant will doubt whether his billion-dollar battleship can cover half of the distance!
"How can this be?"
"In the entire galaxy, only our Ziyun Empire has the technology to manufacture the jump blocking device, and we have never leaked this equipment or technology!"
"It's not like a fifth-level civilization was born on the forward spiral arm, right?"
Well, what Heisha doesn't know is that there is indeed no level 5 civilization born on the front spiral arm, but a level 6 civilization coming from an alien galaxy!
"General, what should we do now?"
"..."
Heisha was silent. This is a good question.
what to do?
Of course he retreated!
Are you kidding me? You know that there is no way to attack the opponent, but you still stay here and act as a target?
However, you must leave some gifts before retreating!
"Immediately release all strategic reconnaissance ships, and then order the entire fleet to evacuate the rear spiral arm immediately!"
"Yes, General!"
Soon, dozens of small strategic reconnaissance ships flew out from Heisha's flagship and quickly moved towards the target location.
Speaking of the strategic reconnaissance ship of the Ziyun Empire, it is actually similar to the strategic reconnaissance ship of the Hitria Empire, one of the four giants in the galaxy.
This is a type of ship specially developed for detection technology. It can effectively block the scanning of all wave bands, and also has stealth camouflage technology, thereby achieving full stealth effects in both detection and vision.
Even for level five civilizations, it is difficult to detect these reconnaissance ships.
Of course, this has no effect on the space radar of a sixth-level civilization!
"Commander, I found that the other party released more than 20 small reconnaissance ships, which should be stealth reconnaissance ships and other types of ships!"
"Well, mark these reconnaissance ships and mark them as unattackable!"
"Yes, Commander!"
After Heisha released the strategic reconnaissance ship, it was immediately captured by the Pangu. In front of the space radar, these so-called stealth reconnaissance ships were as conspicuous as if they were naked.
However, all this was under the command of Lin Yu, and Heisha had no knowledge of it.
Seeing that the released strategic reconnaissance ship did not suffer any attacks, my heart that had been hanging seemed to be a lot easier!
"Order the fleet to enter the wormhole immediately and withdraw from the spiral arm!"
"Yes, General Heisha!"
On the other side, the retreat of the Ziyun Empire's tribute fleet naturally could not escape the detection of Lin Yu's fleet.
"Commander, the opponent has started to retreat towards the wormhole. Do you want the fleet to use space tear to attack?"
Speaking of which, from the beginning of the battle to now, under Lin Yu's order, the fleet has been using an attack called space penetration.
Although this attack is powerful, it is only a single-point attack and has no area-of-effect damage.
Therefore, although the Ziyun Empire was unable to fight back, it did not cause enough damage to cause the fleet to collapse.
After all, Lin Yu's purpose was not to completely destroy the opponent's fleet, but to lead the opponent to discover his ambush circle and then crash the Neutron Battle Star into it.
"No, there is no need. Continue to maintain the current attack method until all opponents retreat into the wormhole!"
