It is absolutely impossible to know that this situation is definitely not out of the question. The fact that the high-level leaders of the three cosmic-level civilizations would have such worries meant that this was a potentially huge possibility.

After all, there is no one who understands the flaws of their own ships better than some of the higher-ups within the three cosmic-level civilizations.

Although the three cosmic-level civilizations have been committed to the research of the soul field over the years because of the huge threat of the ancient civilizations, and have continuously made new and breakthrough achievements in the research and development of soul body detection equipment, it has to be said that because of the lack of some basic cognition of the soul field, the exploration of the three cosmic-level civilizations in this field has always been extremely difficult.

Reflected in reality, that is, the soul body detection equipment produced by the three cosmic-level civilizations is quite unsatisfactory in terms of performance, and it can be used, but it is not easy to use at all, and it has always been far from the ideal detection performance index.

The detection equipment arranged around the wormhole passage to detect whether there is a soul body near the wormhole passage, because it is fixed in a large space platform, there is enough space to install the detector body and a huge energy supply equipment, the detection range is relatively far away, and it can roughly detect the situation within a range of tens of kilometers.

A large number of related detection equipment are densely arranged around the wormhole passage, and the defense of the soul body is absolutely pervasive, and no soul body wants to quietly pass through the wormhole passage without being discovered, so as to ensure the safety of each wormhole passage.

But it is obviously impossible to replicate such a large posture in a military warship.

Under normal circumstances, the length of military warships is only about a few kilometers, and because of the existence of battlestar armaments, cosmic-level civilizations have not vigorously developed war motherships and other similar combat vehicles, so the size of the vast majority of military warships is actually within the range of a few kilometers.

Even if the military warships of the cosmic-level civilization have superior performance, there are even some small space expansion devices inside the battleship, which can expand the storage space inside the battleship that is even larger than the size of the battleship. However, with such a little expansion space, it is actually only able to meet the installation needs of various equipment of warships, and it is impossible for large soul body detection equipment with huge size to be installed inside these warships.

The maximum detection range of those detection equipment installed inside the battleship is actually only a few hundred meters, not even a thousand meters, not even a thousand meters, let alone actively detecting the souls of ancient civilizations that exist at a distance.

Even if there are some ancient civilization soul bodies hiding in some parts of the surface of the battleship that are far away from the detection range of the probe, the warships of the cosmic civilization may not be able to find them.

For the combat fleet of the cosmic civilization, such a poor soul body detection equipment with a small detection range actually serves as a comfort in many cases, so that they will not be blinded, so that they are surrounded by soul bodies but they don't know it.

And for the soldiers inside these warships, this kind of small detection range can't even wrap the hull of the ship, it can be called a soul body detection device, and the greater significance is not to detect the external environment, but to prevent the appearance of soul bodies inside the battleship.

At the very least, there is this kind of equipment installed inside the battleship, once an infected soul body appears, it can be detected and destroyed at the first time, which is more or less useful, as for the other signs of discovering the soul body outside the battleship, this is probably more like a joke in many cases.

In the vast void, if it weren't for the extraordinary range and density of the soul body, it would be a fool's dream to discover the existence of a soul body with such a rudimentary and terrifying soul body detection equipment!

The ancient civilization has been confronting and confronting the fleets of the three cosmic-level civilizations for hundreds of years, and during this period, it is not only the cosmic-level civilization that has deepened its understanding of the ancient civilization, but the ancient civilization has only a deeper understanding of the situation within the cosmic-level civilization.

Therefore, the soul body of the ancient civilization knew the defects of the military warships of the cosmic-level civilization more clearly than the crews of the cosmic-level civilization.

Once they get close to the battleship of the cosmic-level civilization, the souls of the ancient civilization will definitely instinctively hide in the blind spot that the battleship detection system cannot detect, and they will not be detected by the warship detection equipment of the cosmic-level civilization at all.

Therefore, in many cases, I am afraid that it is inevitable that the battleships of the universe-level civilization itself will also become a free ride for the soul body of the ancient civilization, which is not subject to human will.

Even if the warships of the cosmic-level civilization can find traces of the existence of some souls in the battlefield, most of them are only the army of infected souls controlled by the souls of the ancient civilizations, and if they want to rely solely on the patrol and detection of the battleships, they will kill the souls of the ancient civilizations, which even the high-level of the cosmic-level civilizations know, it is simply wishful thinking.

Being able to eliminate the existence of some infected soul bodies to the greatest extent, and destroying part of the soul food of the soul bodies of ancient civilizations as much as possible, has already achieved the combat purpose of a cosmic-level civilization. No one dared to expect that the warships, which were not much different from the blind, would be able to accomplish such a difficult task.

On the contrary, the military warships of these cosmic-level civilizations are actually regarded as huge security risks before they are tested.

Because there is too much possibility, some ancient civilization souls will take the opportunity to cling to the bodies of some military warships, taking the opportunity to get close to the cordon of the core star field.

In this regard, the three cosmic-level civilizations should be wary, which is a normal thing in itself.

After all, once the worry of being taken advantage of by the ancient civilization to sneak into the core star field becomes a reality, then the huge sacrifices made by the three cosmic-level civilizations in order to guard against the ancient civilization will obviously be in vain.

The more ancient civilization souls infiltrated the core star field, the worse the situation would become, and the faster the situation in the core star field would change.

Since the three cosmic-level civilizations have already gained insight into this huge security vulnerability, it is naturally impossible not to take precautions in advance.

But the problem is that even if the cosmic-level civilization is already aware of the seriousness of this security threat, it is definitely not a simple matter to solve it simply.

After all, the number of military warships participating in the operation this time is simply astronomical, and the scale of billions of warships is often billions.

Even if the cosmic-level civilization has specially set up monitoring channels near the war zone, and arranged a large number of soul body detection equipment to form a security detection area, it can quickly screen whether there is an ancient civilization soul body hidden inside and outside the battleship when the battleship opens various internal channels, but it is obviously impossible to identify the safety status of all ships in a short time.

The work efficiency of those detection equipment cannot be so high, and it is very unrealistic to arrange a large number of safety monitoring channels, after all, the layout of each safety monitoring area needs to be installed with a large number of soul body detection equipment, and it must be that kind of extra-large model.

Even with the financial and material resources of a cosmic-level civilization, it is impossible to invest a huge amount of resources in this area, and that is simply unrealistic.

In this situation where it is impossible to monitor the safety status of all ships in a short period of time, the only way for these billions of combat ships to remain within the scope of the combat area after the battle is completed, while sweeping all suspicious situations around them, and eliminating any discovered souls as much as possible, while waiting in line for the security monitoring to pass.

Only those ships that have passed the safety inspection procedures can be mobilized to other areas for reuse, and those ships that have not passed the safety inspection, even if they are allowed to be abandoned in the war zone, the three cosmic-level civilizations will not dare to reuse them, and the security risks are too great, and once anything goes wrong, it will be worth the loss.

However, ships can be idle, but the crews who operate the ships are obviously impossible to be idle for such a long time, and the response plan of the three cosmic-level civilizations is to first concentrate these crews into some ships, and after testing the corresponding ships, they will make special arrangements for the relevant crews.

Fortunately, because of the implementation of unmanned measures, the actual operators of each ship are only a handful, and the crews of tens of thousands of ships can be temporarily concentrated in one ship, and after rapid testing, these crews can be placed as soon as possible, which will not have any adverse impact on the physical and mental health of the crew, so that the rapid evacuation of personnel can be completed.

After the personnel are evacuated, these ships can complete various non-wartime tasks through remote control, but they don't have to worry too much about the problem of idle warships, and they can still exert the residual heat of these warships in the war zone, eliminate the existence of the remaining infected souls in the war zone as much as possible, and reduce their potential harm.

Even after the evacuation of personnel and no need to worry about the safety of the crew, the three cosmic-level civilizations can also gather a large number of ships together and launch high-energy laser cannons to make these warships carry out covering attacks with each other in a relatively low-energy mode.

It can be said that in the face of this expeditionary combat operation launched by the ancient civilization against the core star field, although the three cosmic-level civilizations all have great self-confidence, believing that they have sufficient strength to thwart the invasion of the ancient civilization, but at the same time, the three cosmic-level civilizations do not have even the slightest contempt for the ancient civilization.

From the pre-war preparations, to the tactical arrangements during the operation, or the post-combat security gaps after the battle, the three cosmic-level civilizations have all made plans in advance, and have to check and examine over and over again what aspects still exist.

Hundreds of years of correspondence and confrontation with the ancient civilization have already made the three cosmic-level civilizations put the threat of the ancient civilization as an opponent at the highest level, and they dare not be careless in the slightest when it comes to the ancient civilization, because any carelessness may lead to the loss of the whole situation, and even lead to an extremely dangerous situation, which the three cosmic-level civilizations have long been accustomed to.

Otherwise, if you change to another opponent, the fleets of the billions of the three cosmic-level civilizations will be spread out, except for the civilizations of the same level, the three cosmic-level civilizations will hardly have any forces that cannot be handled, where is there any need to be so careful.

However, in the body of the ancient civilization, billions of warships can certainly bring great strength advantages to the operations of the cosmic-level civilization, but even after the victory of the war, in order to make up for the hidden dangers brought by this massive number of warships, the time, energy and various preparations required are not inferior to the consumption of a large-scale battle.

Only this can be seen that the ancient civilization is infinitely poisonous, and the three cosmic-level civilizations have suffered much when facing the enemy of the ancient civilization.

Fortunately, although the preparations in all aspects are extremely complicated, and the expenditures in each link are also extremely amazing, the three cosmic-level civilizations have all come to the same conclusion when they share a lot of information with each other and deduce the battle chess game from each other, that is, in the face of this long-range attack by the ancient civilizations, the three cosmic-level civilizations have a good chance of winning.

With a relatively long preparation time, a solid family background, and countless battles with ancient civilizations, a deep understanding of ancient civilizations, countless chessboard deductions, and countless examining the pros and cons, the three cosmic-level civilizations have slowly settled down, and decided that this time the ancient civilization is definitely a bad move.

Although the ancient civilization has been working its territory for many years, and has accumulated a lot of net worth after a long period of development, if you want to rely on this bit of wealth to fight with the three cosmic-level civilizations with comprehensive strength, even if it has the special factor bonus of the ancient civilization, it is tantamount to using the mantis arm as a car. It is destined to have a fiasco waiting for the ancient civilization to taste, the victory rate of the three cosmic-level civilizations is more than ninety percent, I really can't understand why the ancient civilization is so unwise, knowing that the probability of failure is infinite, but still have to go their own way.

However, thinking that there is a high probability that their side will usher in an unprecedented victory, the high-level leaders of the three cosmic-level civilizations can't help but feel a little good!
