However, the losses caused by the ten steel battle star troops of the three cosmic-level civilizations to the ancient civilization were too serious, and in such a raid tens of thousands of light years deep into the territory, all the important industrial areas that were destroyed exceeded a hundred, involving chemical industry, smelting, metal processing, high-precision instrument manufacturing, equipment production, large-scale machinery production bases, and so on.

In addition to the destruction of industrial production bases, many important educational bases, important scientific research and development bases, many administrative planets, ecological planets, etc., in the territory of ancient civilizations, have been devastated, just the loss of elite talents from all walks of life is as large as billions, and the number of casualties among ordinary people is as high as 50 trillion!

After competing with the three cosmic-level civilizations for thousands of years, only the ancient civilization has taken advantage of the three cosmic-level civilizations, and the three cosmic-level civilizations have never had any benefits from the ancient civilizations.

In the face of such a huge loss, it is conceivable how the ancient civilization could endure this anger.

Although the troops were stationed in various key areas bordering the three cosmic-level civilizations before, the internal defense of the ancient civilizations was extremely lax, making the ten Iron Battlestar troops of the three cosmic-level civilizations seem to be in a no-man's land, and they can wreak havoc and destroy as much as they want.

However, in the process of returning these Iron Battlestar troops, the combat troops of the ancient civilization had enough time to calmly arrange, and arranged one defense line after another on the road ahead of these Iron Battlestar troops.

You must know that these steel battle stars of the three cosmic-level civilizations, the way they evacuated had been carefully planned in advance before launching the attack, and the destination of the return trip was also far away from the garrison area of the ancient civilization, but Rao was so, through the rapid turnover of wormhole channels in the territory, the ancient civilization still locked the retreat destination of the steel battle star troops of the three cosmic civilizations in advance, and laid out a heavy defense line in the relevant star fields in advance, and the countless battleship troops and infected soul body troops were determined to leave or completely destroy all the steel battle star troops, at least some of them！

In order to achieve such a goal, the ancient civilization can be said to have spared no expense, and even the grand strategy of attacking the third universe-level civilization for many years has been temporarily shelved, and as many as tens of billions of ships have been directly transferred from the massive combat forces that have launched attacks on the third universe-level civilization, so that during this period of time, the wormhole defense lines of the third universe civilization can be described as unprecedentedly quiet and peaceful, and almost all the battles have been completely terminated.

From this point of view, it is obviously completely worthwhile for the Third Universe-level civilization to dispatch four Iron Battlestar troops in this operation, just because of this raid, the ancient civilization has a great possibility to change its previous battle plan against the third universe-level civilization.

However, the decompression of the wormhole defense troops on the front line of the third universe-level civilization in exchange for the result is that the Iron Battlestar troops of the three universe-level civilizations gradually felt more and more combat pressure during the retreat.

You must know that now, as the Iron Battlestar troops are getting closer and closer to the end of their retreat, and are about to break through the heavy interceptions of the ancient civilizations, all the Iron Battlestar troops are gradually surrounded by a large number of enemy troops.

Around the location of these Iron Battlestar troops, the ancient civilization can be said to have no idea how many troops have been filled in before and after, inside and out, and the combat ships responsible for intercepting the Iron Battlestar troops before were directly transferred to the new defense line by the ancient civilization through the wormhole channel after the mission failed, so that the enemy troops faced by each Iron Battlestar unit were sky-high.

Although the short-range space-time jump of the Iron Battlestar is extremely efficient and the distance is extremely long, ordinary cosmic-level warships can't catch up at all, but the problem is that the short-range space-time jump of the Iron Battlestar also has a cooldown period, and during the time period when the jump function is cooled, the Iron Battlestar only has the ordinary superluminal speed navigation ability, which gives the ancient civilization fleet a chance to chase and intercept and even win the battle!

The Iron Battlestar troops have been entangled by the fleets of ancient civilizations again and again, although each time these Iron Battlestars have finally managed to escape, and even the Iron Battlestars themselves have not even scratched the surface, but this does not mean that the ship-carrying forces of the Iron Battlestars can also be so lucky.

Although there is a Steel Battlestar as a backing behind it, it has brought huge battle damage to the combat ships of the ancient civilization, but under the crazy attack of the massive warships of the ancient civilization, the ship-carrying ships of the Iron Battlestar are also constantly consumed and reduced.

If the Iron Battlestar troops of the three cosmic-level civilizations only need to face some cosmic-level combat ships, the battle damage of these ship-carrying ships is nothing to the Iron Battlestar.

After all, although the carrier fleet plays a great role for the Iron Battlestar, in a sense, they are the main force of the battle, and can complete many tasks that the Iron Battlestar itself is inconvenient and unable to complete, but even if all the carrier ships are damaged, this is not too much pressure on the Iron Battlestar.

Because even during the cooldown period of the short-range space-time jump, even if all the ship-carrying forces are lost, the Iron Battlestar itself is not without self-protection ability, not to mention how large the scale of combat weapons the huge Iron Battlestar as a planet is loaded on the outer armor layer, and how powerful the self-protection ability is.

Even if it is 10,000 steps back, the outer protection and weapon system of the Iron Battlestar has been completely destroyed, but this is far from the point of exhaustion for the Iron Battlestar. At any moment, the Iron Battlestar can shed its shell, remove the outermost layer of armor, reduce its size, discard unnecessary loads, and re-reveal a new layer of outer armor, and use new weapons and defenses to deal with all its enemies.

By peeling the shell again and again, the Iron Battlestar can abandon the unimportant parts of the periphery in exchange for its own safety, even if it is to the worst point, the Iron Battlestar can even directly abandon all the armor layers on the periphery, and directly forcibly start the jumping device and escape calmly with all the devices in the core。

If you really come to this point and abandon all the outer armor, although the loss of Iron Battlestar is not small, a large amount of volume and weapon systems are lost, but as long as the core of Iron Battlestar is kept, it still represents a victory.

After all, although the outer armor of the Iron Battlestar is thick and heavy, compared to the core part of the Iron Battlestar, these peripheral things are nothing more than worthless things, and the cost of this huge block can only account for one-tenth of the total cost of the Iron Battle.

And from the aspects of actual importance, production difficulty, production cycle, irreplaceability, etc., even the entire shell of the Iron Battlestar together is not as important as one-thousandth of the core part of the Iron Battlestar.

With such a systematic design, if there are only a few combat ships to surround the Iron Battlestar, then the possibility of the Iron Battlestar successfully escaping is undoubtedly very high.

The problem is that the ancient civilization is not an ordinary cosmic-level civilization, it has a large number of soul body troops to use, and this is a major nemesis of the Iron Battlestar, the ancient civilization used the soul body troops to directly invade the inside of the Iron Battlestar, causing a large number of casualties inside the Iron Battlestar, and the complete collapse of the personnel control system.

Without the direct control of the controllers inside the Battle Star, many of the specific functions of the Iron Battle Star are actually impossible to control remotely, which is still unavoidable even with the intelligent system inside the Battle Star.

At least it is not an easy task for the Iron Battlestar to forcibly activate the space-time jump device and successfully escape, and now the ten Iron Battlestar troops of the three cosmic-level civilizations are still in a situation where they are surrounded by ancient civilizations, even if they forcibly carry out space-time jumping, they will still fall into the encirclement of the ancient civilizations in the end.

After all, if you don't abandon the outer shell of the battle star, the forced space-time jump will jump with the battle star shell, which has a very big impact on forcibly activating the jump device during the cooldown period, and the jump distance will be greatly attenuated. At that time, I am afraid that more than one Iron Battlestar will really stumble and fall under the control of the ancient civilization.

The ancient civilization has a deep understanding of the Iron Battlestar, and it is very likely that it has all the knowledge system of the Iron Astrology, if these Iron Battlestars really fall into the hands of the ancient civilization, then I am afraid that these Iron Battlestars will eventually be forcibly cracked by the ancient civilization The control system will eventually be controlled by the ancient civilization.

At that time, the three cosmic-level civilizations can really be called stealing chickens and rice, and they will lose to their grandmother's family, and they will directly advance the date of the demise of their own civilizations by I don't know how many years.

And if we want to prevent all this from happening, the most important key is to keep a considerable number of ship-carrying forces and ships in existence.

Because with the assistance of a large number of soul body detection equipment loaded inside the Iron Battlestar, the Battlestar has a large number of ship-carrying ships to escort it, so it can quickly destroy all the soul body troops moving around the Iron Battlestar in a timely manner, and avoid the end of being invaded by the soul body troops inside the Iron Battlestar.

Therefore, when fighting with the troops of the ancient civilization, these ship-carrying units that originally belonged directly to the consumables can be said to have a qualitative improvement in the importance of the Iron Battlestar, relatively speaking, a large number of ship-carrying troops have been lost again and again in the collision with the encirclement and suppression forces of the ancient civilization, which naturally means that the situation is becoming more and more dangerous for the Iron Battlestar.

However, retreating within the ancient civilization, such a dangerous situation will not change in the slightest due to the increasingly anxious mood within the Iron Battlestar troops, and even as more and more troops of the ancient civilization surround them, the Iron Battlestar troops have fallen into further stalemate, as if they have fallen into a deep quagmire, and they are more and more powerless to control themselves by countless enemy troops.

In the course of the battles, all the carrier-carrying ships of the Iron Battlestar Force had been consumed in large quantities, and now under the entanglement of countless combat units of the ancient civilization, the consumption rate of these carrier-carrying ships has accelerated even more rapidly.

Countless ancient civilization combat ships are attacking these carrier ships like a tide, and along with these ancient civilization combat ships, there are also a large number of infected soul body troops participating in the war in a low-key manner.

Countless infected souls are infiltrating the interior of the carriers, and some of the ships that are fighting are still fighting bravely and flexibly one moment, and the next moment they suddenly become rigid and unresponsive, most of which means that the infected souls have penetrated deep into the interior of the carrier ships and launched an attack on the soldiers inside the ships.

Even if there is soul body detection equipment inside the ship, it will not be able to protect the crew inside the battleship in the case of a large number of infected soul bodies, and the ships that have such an accident will often be taken advantage of by the combat ships of the ancient civilization and directly destroyed with one shot.

At this critical moment of encircling and suppressing the Iron Battle Star, the fleets of the ancient civilizations didn't even care about capturing the carriers, and their first reaction was to take the opportunity to destroy them, anyway, for the ancient civilizations, these infected souls were worthless, and it would be a lot of money to be able to consume a carrier.

While a large number of infected souls are attacking carriers, there are also even more massive infected soul troops attacking the Iron Battlestar!

Countless infected souls swarmed to the Iron Battlestar, relaying each other to penetrate into the alloy layer of the Iron Battlestar, and this information was detected by the Iron Battlestar through the soul detection equipment, and a large number of ship-carrying ships launched high-energy weapon attacks on those infected souls mercilessly under the guidance of the information.

While destroying a large number of infected souls, this kind of attack that deliberately reduces the strength of high-energy weapons often cannot even damage the surface coating of the Iron Battlestar's alloy armor, which can ensure the safety of the Iron Battlestar to the greatest extent.

Of course, the safety of the Iron Battlestar itself is not only protected by carriers, a large number of intelligent robots inside the Battlestar have also been sent out, constantly destroying all infected souls found on the surface of the Battlestar.

However, even with such layers of protection, all the Iron Battlestars were still surrounded by a steady stream of infected souls, layer after layer, and countless infected souls were rushing towards the Iron Battlestars as if they didn't need money, and some had even passed through the heavy armor layer and entered the interior of the Battlestar.
