Four hundred and twenty-one forcing back the tribute fleet

For the scientific and technological civilization in the middle of the fifth level, its understanding of space technology is only just a door.

Not to mention that only the sixth-level civilization has the means of space attack, they simply can't understand it!

However, even if he didn't understand it, Heisha knew clearly that he was attacked, but he didn't understand the opponent's attack method at all.

It's fine if you just don't understand the means, but the most important thing is that you don't even know where the other party is.

At this moment, a very absurd thought flashed in Heisha's heart!

Will the enemy launch an attack on you from a few AUs away?

As far as the current detection technology of the Ziyun Empire is concerned, it can be divided into short-distance, medium-distance and long-distance detection.

Among them, the scanning detection of short distance and medium distance is the most used. As for the long distance detection, it is generally not used under special circumstances.

This has a lot to do with energy consumption. If the detection of the maximum distance is enabled without interruption, the energy consumption is also quite terrifying.

Basically, the energy consumption increases exponentially for every additional 1AU of scanning distance.

After all, in the mid-level 5 scientific and technological civilization, its detection technology has not yet involved the in-depth application of space technology, and both distance and energy consumption are very unsatisfactory.

"Start long-distance detection immediately and find out the enemy!"

"General, what is the scanning distance?"

"At the maximum value of 20AU!"

"Yes!"

While responding, the adjutant also took a deep breath.

Could it be that Admiral Heisha suspects that the enemy is at a distance of more than ten, or even twenty AU?

how can that be?

The adjutant tried to break his head, but he couldn't figure out what weapon it was that could attack such a long distance!

However, looking at the tactical image, the constantly disappearing one's own target, and the outside of the ship where there is no sign of any attack, but the battleship is being pierced one after another.

The adjutant also swallowed and immediately followed Heisha's order!

No, really?

A minute later, standing behind the enemy search officer, the adjutant stared at the result of the detection with wide eyes, feeling a little stunned for a while!

"General... General... Suspicious targets were found at a distance of 10AU, the number of which is about 10 million warships, but no trace of fire on these targets was detected!"

"10AU? Whether it's them or not, immediately send one, no, two battleship formations to control them and annihilate them on the spot if they resist!"

"Yes!"

Originally, Heisha planned to send a formation (according to the establishment of the Ziyun Empire, a battleship formation was 100 million battleships), but after thinking that the enemy had such a strange 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 sixth-level civilization, and the biggest possibility should be the development of some kind of special weapon.

Therefore, 200 million warships to destroy 100 million warships should be more than enough.

It's just that reality quickly poured cold water on him!

"General Heisha, the third and fourth formations reported that they were unable to make the transition, and they were suspected of being interfered by the transition blocking device!"

At this moment, the adjutant suddenly turned around and shouted at Heisha with a worried look on his face.

Can this be in a hurry?

If you are beaten here, you will not be able to fight back, but the suspected enemy fleet is outside 10AU, and now you are told that it has encountered the interference of the transition blocking device and cannot transition.

What does not being able to jump mean?

It means that you can't get close to the other's fleet at all!

Approaching at sub-light speed?

Don't say whether people will cooperate with you to move in the opposite direction to maintain distance!

And even if people don't run, let you approach, the adjutant is very doubtful that his one-billion battleship can finish half of the journey!

"how can that be?"

"In the entire galaxy, only our Ziyun Empire has the technology to manufacture the transition blocking device.

And we have never flown out this kind of equipment or technology! "

"It's not necessarily that a fifth-level civilization was born on the front spiral arm, right?"

Well, what Heisha doesn’t know is that there is indeed no fifth-level civilization born on the front spiral arm, but a sixth-level civilization from an alien galaxy!

"General, what should we do now?"

"..."

Heisha was silent, which is a good question.

What should I do?

Of course retreat!

Just kidding, knowing that there is no way to attack the other party, can you continue to stay here as a target for others?

However, before retreating, you must leave some gifts!

"Immediately release all the strategic reconnaissance ships, and then order the entire fleet to evacuate to the rear spiral arm immediately!"

"Yes, General!"

Soon, dozens of small strategic reconnaissance ships flew out of Heisha's flagship and quickly swept towards the target's position.

Speaking of the strategic reconnaissance ship of the Ziyun Empire, it is actually similar to the strategic reconnaissance ship of the Citria Empire among the four giants of the Milky Way.

This is a type of ship specially developed for detection technology, which can effectively block the scanning of all bands, and also has stealth camouflage technology, so as to achieve the effect of full stealth whether it is detection or vision.

Even if it is a fifth-level civilization, it is difficult to detect these reconnaissance ships.

Of course, this has no effect on the space radar of the sixth-level civilization!

"Commander, I found that the other party has released more than 20 small reconnaissance ships, which should be stealth reconnaissance ships!"

"Well, mark these reconnaissance ships, and also mark them as unattackable!"

"Yes, Commander!"

After Heisha released the strategic reconnaissance ship, it was immediately caught by the Pangu. In front of the space radar, these so-called stealth reconnaissance ships were as conspicuous as they were without clothes.

However, under the command of Lin Yu, Heisha had no idea.

Seeing that the released strategic reconnaissance ship has not suffered any attack, the heart that has been hanging seems to be a lot easier!

"Order the fleet to immediately enter the wormhole and withdraw to the rear spiral arm!"

"Yes, General Heisha!"

On the other hand, the retreat of the Ziyun Empire's tribute fleet was naturally unable to escape the detection of Lin Yu's fleet.

"Commander, the other party has begun to retreat in the direction of the wormhole. Do you want the fleet to use space tearing to attack?"

Speaking of which, from the beginning of the battle to the present, under Lin Yu's order, the fleet has been using an attack called space piercing.

Although this attack is powerful, it is only a single-point attack and has no area-killing effect.

Therefore, although the Ziyun Empire was powerless to fight back, it did not bring enough damage to cause the collapse of the fleet.

After all, Lin Yu's purpose was not to completely destroy the opponent's fleet, but to lead the opponent to find his own ambush circle, and then ram the Neutron Battle Star into it.

"No, there is no need, continue to maintain the current attack method until all the opponents withdraw into the wormhole!"

"Yes, Commander!"
