After all, in this starry sky battlefield, the maneuverability of a cosmic-level civilization-level military ship is really a headache, and a space-time jump is a distance of several light years!

For such a difficult opponent, the fleets of the three cosmic-level civilizations want to intercept all the ships, not let any of the ships become fish in the net, and solve the problem of whether they can go with the flow, and they have to run behind the ass of the ancient civilization fleet. In such a chase battle, there is a lot of room for big mistakes.

What's more, the biggest advantage of the three cosmic-level civilizations lies in their unparalleled comprehensive strength.

Although the ancient civilization reintegrated a new set of production systems with relatively complete industrial categories with the help of the residual industrial system of the cosmic-level civilization within its own territory, this industrial production capacity is too insignificant compared to the production capacity of the cosmic-level civilization officially.

Even if the ancient civilization has borrowed this set of industrial equipment left over from the cosmic-level civilization to reorganize the production system, secretly accumulated resources for hundreds of years, and mastered an unprecedentedly large number of fleets, but the ancient civilization has almost exhausted all of its own combat power, and in every core star field battlefield, the ancient civilization has only invested hundreds of millions of fleets.

In order to guard against various sneak attacks that may exist in ancient civilizations, and to prevent ancient civilizations, the three cosmic-level civilizations took the opportunity to attack some other core star fields through the wormhole channel while launching a large fleet to attack some core star fields, which led to the fact that even if the three cosmic-level civilizations were to draw fleets, they could only extract a small part of the mobile fleet without affecting the defensive strength of other core star fields.

However, it is this small part of the fleets that have been drawn out and distributed among the core star fields that are ready to meet the attacks of the ancient civilization fleet, and the fleet size that the cosmic-level civilization official can invest in each star field is dozens of times that of the ancient civilization fleet.

The size of such a large fleet is obviously enough for a cosmic-level civilization to arrange its own defense line with relative ease.

In order to ensure the foolproof operation and not give the ancient civilization fleet any opportunity to take advantage of, the three cosmic-level civilizations have made the same preparations in their respective defense line arrangements.

The entire force of defense in each core star field has been divided into two systems, and a part of the fleet is responsible for the interception and destruction of the first line, and as the front-line combat operation force, it must destroy all the living forces of the ancient civilization as much as possible.

In addition to destroying all ships of ancient civilizations that can be destroyed, these ships of cosmic civilizations are also responsible for completing the task of discovering and removing the souls of ancient civilizations.

As such a long-range attack that was almost full of all its might, according to the guesses of the three cosmic-level civilizations, the souls of the ancient civilizations would definitely not be absent.

For these ancient civilization soul bodies, as long as there is a chance to destroy them, the troops of the three universe-level civilizations will definitely not tolerate the traitors and will not leave them with any affection.

After all, the reason why the three cosmic-level civilizations have developed into this chaotic situation is, in the final analysis, the most fundamental reason is the existence of ancient civilizations.

Without the turmoil of the ancient civilization, how could the three cosmic-level civilizations come to this point today, not to mention that a large number of territories have been torn apart, and the clansmen of the same cosmic-level civilization themselves will still fall to the point where they are like enemies, just with this national hatred and family hatred that goes deep into the bone marrow, the fleet members of the cosmic-level civilization will definitely not let go of any opportunity to hit the soul body of the ancient civilization.

What's more, the soul body of the ancient civilization is still the most dangerous existence, once the soul body of any ancient civilization becomes a fish that slips through the net, or even penetrates into the core star field, it will definitely be a disaster, even for the sake of their own safety, the officers and soldiers of the universe-level civilization are inclined to kill all the soul bodies of the ancient civilization as much as possible. Their priority is even ahead of those ancient civilization warships, and they definitely didn't let go of the mistakes.

Considering that after the war started, the soul body of the ancient civilization was likely not only to stay inside some spaceships honestly, but also to get off the ship halfway and take the opportunity to fish in troubled waters on the battlefield, so the three cosmic-level civilizations have already determined their course of action in their combat strategies, and all ships must turn on the soul detection equipment at any time on the battlefield to search for all signs of the existence of the soul body of the ancient civilization.

However, all large-scale soul bodies that are discovered must be destroyed as soon as possible, even if they miss the destruction of the ships of some ancient civilizations because of this, they will not hesitate. From the degree of attention paid to the three cosmic-level civilizations, it can be seen how much the three cosmic-level civilizations hate the soul bodies of the ancient civilizations.

In addition to these relevant ships that are responsible for specific combat operations on the front line of the battlefield, more ships have to carry out multi-level interceptions in the rear defense line, check for omissions and fill in leaks, and carry out a large amount of related logistical support work.

After all, the front-line warships are responsible for front-line operations on the chaotic battlefield, and their targets are often a small number of ships in front of them.

Therefore, the follow-up multi-echelon interception team is indispensable.

These subsequent interceptor fleets generally divided the battlefield in a grid pattern, defending against incoming enemies from all directions. However, after the fleets of the first line come into contact with each other, it is predicted in advance which direction there will be more enemies and which direction will be larger, so the troops in the relevant directions will be more inclined in these directions, but the ships in other directions will only be reduced by a part, and will not be completely emptied.

Because the range of time and space jumps on the battlefield is too large, and even some ships with better concealment are likely to not be intercepted, at this time, a part of the fleet is arranged in each direction to form an all-round layout, so as to intercept all ships that slip through the net as much as possible.

Under the heavy obstruction of such a similar multiple lines of defense, no matter how many ships the ancient civilization put into the battlefield, they will only suffer heavy losses, and after the interception of multiple lines of defense, even if they are cunning like rabbits, most of them will only be caught.

However, this layer of interception fleets is mainly responsible for the operational aspect, and after these multi-layer interception fleets, it is the core part of the ancient civilization defense system, which is responsible for the overall monitoring, collection, analysis and other logistics of battlefield information.

These logistics fleets are not only equipped with various types of cutting-edge and sensitive information-gathering equipment, but they are also responsible for protecting some large-scale information-gathering equipment, some battlefield information filtering systems, and carrying out comprehensive collection and monitoring of all kinds of information on the battlefield, providing valuable operational intelligence for the front-line combat fleet, and so on.

After all, the battlefield is too big, and the purpose and mode of operations are too special, and the importance of real-time monitoring information on the battlefield has increased by a few notches compared with conventional operations.

Under normal circumstances, even if multiple interception fleets cooperate with each other, it is also difficult to maintain a delicate and subtle insight into the overall battlefield, and some ships are ignored because of the complexity of the battlefield situation, which is simply risk-free under conventional combat conditions, after all, it is generally enough to destroy the enemy's main fleet, and it is impossible for the remaining small fleet to set off any more storms。

However, in the battle with the ancient civilization, in order to prevent the infiltration of the soul body of the ancient civilization, the attitude of the cosmic-level civilization is that not a single ship can be spared, and not a single fish that slips through the net is allowed to exist, and the requirements for the control of the battlefield are far beyond the ability of the front-line combat troops.

It is very necessary to arrange a large number of professional logistics fleets to be responsible for all battlefield intelligence related work after the front-line combat units.

What's more, it is impossible for the ancient civilization not to think that the three major cosmic-level civilizations will know their situation well, in order to ensure that their own fleet breaks through the interception of the large-scale fleet of the cosmic civilization, the fleet of the ancient civilization is equipped with a part of the battlefield information jamming ships, which is simply a matter of course.

Therefore, in order to eliminate all information interference and grasp all the clues in the battlefield, the three cosmic-level civilizations have prepared a special logistics fleet in the rear of the combat troops, which is naturally a normal and reasonable thing.

Even the three cosmic-level civilizations have taken into account the complexity of the battlefield situation and the extremely demanding intelligence capability requirements for battlefield information, and these special situations have never been encountered in all the wars experienced by the three cosmic-level civilizations before, and even the cosmic-level civilizations do not have corresponding battlefield intelligence collection ships and equipment that can perfectly meet the needs of operations.

After all, it is necessary to lock on billions of different warships on the battlefield at the same time, to meet the needs of different tasks such as distinguishing friend from foe, locking the location and trajectory of enemy warships, detecting jump nodes, etc., such extreme battlefield intelligence needs have long exceeded the normal combat needs, and there will naturally be no relevant special equipment within the three cosmic-level civilizations, and even if a large number of related equipment is collected to form a full-range monitoring network, it is difficult to meet the needs of war.

This compelled the three cosmic-level civilizations to immediately transfer the requirements for the relevant battlefield intelligence and reconnaissance systems to some top-level research institutes after realizing their own deficiencies in intelligence capabilities, and asked these organizations to develop a new battlefield intelligence system in the shortest possible time that can fully meet the operational needs in accordance with operational requirements.

Although the requirements of such a battlefield intelligence system are extremely high, the various scientific and technological reserves of the cosmic-level civilization are incomparably abundant, and the reason why there was no similar battlefield intelligence system in the past is not that the cosmic-level civilization cannot achieve this extreme, but that the fleet of the cosmic-level civilization does not have this demand.

Therefore, after the relevant research tasks were arranged, the research progress within the three cosmic-level civilizations was extremely fast, and the design was finalized in less than a year, and the relevant mass production work was completed in less than half a year, and a sufficient amount of equipment was produced and delivered to the operational frontline of the relevant core star field, without delaying the combat preparations of the cosmic-level civilization.

However, the research and development of the battlefield intelligence system is only a part of the long-range raids of the three cosmic-level civilizations to deal with the ancient civilizations, and even only a small part of them.

In order to deal with the attacks of the ancient civilizations, the three cosmic-level civilizations need to prepare for a myriad of things.

The sand table deduction of the entire war in the early stage allowed the three cosmic-level civilizations to have a comprehensive control of the whole war, and then according to the various relevant information obtained from the sand table deduction, the high-level leaders of the three cosmic-level civilizations carried out a comprehensive division of labor in combat preparations.

Various special assault research and development tasks for the needs of war are only one of them, and other equally important or even more important things include the recruitment, screening, and deployment of a large number of fleets, and a large number of fleets come to the core star fields to prepare for war, in order to meet the various needs of the fleet, there is also a large supply of various materials and equipment.

Immediately after gathering sufficient troops, while closely monitoring the progress of the ancient civilization fleet, the three cosmic-level civilizations conducted many war rehearsals for their respective fleets, and conducted simulated war drills, so as to make war preparations as fully as possible and ensure the victory of the war.

In addition to these preparations in the early stage of the war, the three cosmic-level civilizations also planned and prepared in advance for the later arrangements after the end of the war.

If it is a war with other civilizations and other forces, these things in the later stages of the war are not prepared for the cosmic-level civilization.

Because in addition to the other enemies of the ancient civilizations, the three cosmic-level civilizations have completely completed the crushing, in the face of any enemy, the fleets of the three cosmic-level civilizations only need to consider fighting over, and then after the fleet returns, they will be rewarded according to their military merits, there is not much superfluous, things that need to be prepared in advance, everything has existing rules, just do things according to the rules.

However, in the war with the ancient civilizations, similar preparations in the later stages of the war are indispensable, and this can even be said to be a matter of life and death for civilizations.

Because of any previous war with the ancient civilizations, an almost lingering nightmare for the three cosmic-level civilizations has always existed, that is, the infection of the soul virus.

When they first fought with the ancient civilization, the three cosmic-level civilizations did not notice this problem, and the consequence was that the soul virus was infiltrated into the internal territory of the cosmic-level civilization with a large number of soldiers, and a large number of soldiers who were infected with the soul virus in advance encountered the ancient civilization, and when they encountered the ancient civilization, it was a whole fleet, and the whole fleet had to be detonated by the virus and easily wiped out!
