PS: Thank you for the monthly ticket support of Wei Bozi and Guang over there! Thank you very much!

Therefore, after hundreds of years of painstaking construction, among these troops who are at the forefront and are originally intended to confront the ancient civilization, there are already a large number of cutting-edge equipment prepared for the soul body, and the density of related equipment is rare even in the core area of the cosmic-level civilization.

Among such front-line troops, it is definitely the most deadly and dangerous area for the souls of the ancient civilizations, and if the souls of the ancient civilizations are not careful, they will encounter fatal dangers and huge setbacks.

If the officers and soldiers who were armed by the battle stars discovered the infiltration of the soul body of the ancient civilization and launched targeted defense and detection operations, then maybe before the infiltration troops of the ancient civilization infiltrated the depths of the battle star army, these people of the ancient civilization would have been discovered and eliminated by the officers and soldiers of the cosmic-level civilization first.

Although this possibility is only a very small possibility, the probability of it actually happening is extremely low. After all, the infiltration of the soul body of the ancient civilization is coordinated by the internal personnel of the cosmic-level civilization, and the soul body of the ancient civilization is not easy to be detected, and it is unprepared to want to infiltrate the battle star armed forces and infiltrate the front-line troops, in this case, it may be even smaller than the smallest, and under normal circumstances, it is easy to achieve the infiltration goal.

But no matter how small the probability of failure is, it still exists. And as long as this danger exists, it contains considerable danger, and there is a possibility of failure that cannot be ignored.

The number of clansmen who have the opportunity to infiltrate the front-line troops on a transgalactic spaceship in the first batch of ancient civilization souls is quite limited, and the ability of such limited infiltrators to resist risks is already seriously insufficient, relatively speaking, the possibility of this infiltration failure is even more serious, and the ancient civilization must not be careless.

Originally, as an infiltration operation against the front-line troops of the cosmic-level civilization, if possible, the ancient civilization naturally arranged as many personnel as possible if it wanted to infiltrate as many people, but those military personnel controlled by the ancient civilization were also limited in ability.

In the cargo compartment of an intergalactic spaceship, which is already short of space and limited capacity, it is quite valuable that they can provide a certain amount of idle space for the infiltrators of ancient civilizations.

Even such a little idle space is already a little extra space that these military high-ups can squeeze out after their best efforts, and this bit of transportation space was originally even a little potential right of the military high-level to seek personal gain, and now it is the limit of what they can do to the ancient civilizations, and no matter how much they do, they can't do it at all.

Therefore, within the voyage cycle, including the soul body food and the soul body of the ancient civilization, the infiltration personnel that the ancient civilization can arrange are also quite limited, which is completely not affected by the will of the ancient civilization, it can be said that it is good to be able to insert some personnel into this opportunity, and there is no room for picking.

As the top technological creation of a cosmic-level civilization, the cost and operating costs of the transgalactic spacecraft are also extremely considerable.

Even cosmic-level civilizations are extremely cautious when using this kind of transgalactic spaceship, and what they cherish is not that there is a spaceship that can depart in a short period of time, and usually there is a life cycle.

Even in order to maintain control over the front-line battlestar armament, the cosmic-level civilization has maximized the frequency of the use of the battlestar armament, but usually only one intergalactic spaceship can be dispatched for a month or so.

And the right to transfer the transgalactic spacecraft once a month is not completely in the hands of the military forces controlled by the ancient civilization, and the ancient civilization must wait for more than five months before it can board a transgalactic spaceship and send a small number of personnel to infiltrate the front-line troops.

Moreover, the control of the ancient civilization over the military of the three cosmic-level civilizations has only opened up the situation among the military of a cosmic-level civilization, and it can slightly touch such top-level strategic equipment.

Among the other two cosmic-level civilizations, the military power controlled by the ancient civilization was far from reaching the level of being able to penetrate the front-line troops.

So far, there is still a considerable distance from real success! Ancient civilizations are still far from being able to sit back and relax.

However, even so, the news of the successful start of infiltration into the frontline troops of the Meteorite Star Sea Great Galaxy still made many souls of the ancient civilization feel sincere joy, because this is definitely a crucial step, and its importance can be said to be impossible to overstate.

This kind of progress can be said to be one of the greatest achievements of the ancient civilization in the three cosmic-level civilizations in more than 100 years, and it is the greatest achievement made by the ancient civilization after years of hard work.

The souls of the entire ancient civilization were waiting for the feedback from the frontline troops of the meteorite star sea system, and before the first batch of ancient civilization souls successfully infiltrated the troops, and completed a series of work to release viruses, control personnel, and feedback information to the frontline troops, the souls of the ancient civilizations all felt an unprecedented sense of apprehension.

This kind of infiltration seems to be no different from those infiltration operations before the ancient civilizations, but it is more dangerous, the feedback cycle is longer, and what is more terrible is that if it fails, it may lead to serious consequences! This makes all the souls of the ancient civilization who know the inside story have to worry about it.

Although the number of clansmen of the ancient civilization has always been seriously insufficient, in the eyes of the ancient civilization at this time, the lives of those limited infiltrators are not the most precious, and even the long cost of an operation is not the most important, the most important thing is that even if the infiltration operation fails, all the infiltrators of the ancient civilization are eliminated, but this infiltration channel must not be exposed.

It is absolutely impossible for the frontline troops of the Meteorite Star Sea Great Galaxy to realize that the infiltration channel of the soul body of the ancient civilization is with the convenience of the transgalactic spacecraft! This is what the ancient civilization is most worried about!

Because once this situation is exposed, it will definitely be a fatal blow to the ancient civilization, and the result of the infiltration of the ancient civilization for hundreds of years will be destroyed in one fell swoop, and the consequences are unimaginable.

Once the official high-level leaders of the cosmic-level civilization know that the soul bodies of the ancient civilization are infiltrating the front-line combat units of the meteorite star sea galaxy by taking a cross-galaxy spaceship through the internal channels of the military, then they will definitely react as soon as possible, and carry out an inventory and transfer of a series of military system personnel who are responsible for the affairs related to the cross-galaxy spacecraft.

What's more serious is that once the cosmic-level civilization strengthens the inspection of the materials transported by the transgalactic spacecraft, and the ancient civilization wants to use this channel to infiltrate the front-line troops, it will become a completely impossible thing, and the infiltration channel that the ancient civilization has worked so hard to open will be completely closed before it has completely failed to play a corresponding role, and this is absolutely fatal to the strategic attack of the ancient civilization.

The ancient civilization itself was able to complete the control of this part of the military forces, which was already the result of various coincidences, and it cannot be said that it is completely impossible to reopen this channel, but the difficulty is bound to increase countless times.

Even with the infiltration and control strength of the ancient civilizations, the possibility of achieving this level is completely minimal, and it is basically resigned to fate.

Therefore, for the ancient civilizations, as long as there is the slightest possibility, they will never want to see this infiltration line discovered by the front-line troops of the cosmic-level civilization.

In order to avoid such a thing as much as possible, when the ancient civilization arranged this infiltration operation against the frontline troops of the universe-level civilization, each batch of infiltration personnel was arranged with the most elite and powerful personnel in the ancient civilization, and all the infiltration members were composed of the remnants of the ancient civilization, and none of them were indiscriminate guys.

In terms of the specific infiltration plan, the ancient civilization collected all the information that could be collected, analyzed various possibilities according to the situation mastered, and arranged the countermeasures one by one, and the most basic goal of action was not to expose their infiltration paths under any circumstances, and not to make the officers and soldiers of the front-line troops of the cosmic-level civilization realize that they had infiltrated by a transgalactic spaceship.

Fortunately, the advantage of the ancient civilization is that although the three cosmic-level civilizations have always been very clear about the infiltration of the ancient civilization within them, they do not know that the main goal of the ancient civilization's recent action is to solve their possible war in the meteorite star sea galaxy.

Under the premise of not knowing the big goal of this ancient civilization, the three cosmic-level civilizations would not have thought that the ancient civilizations would do everything possible to infiltrate their front-line combat troops through the internal channels of the cosmic-level civilization, which is a huge blind spot, only if the ancient civilizations deal with it properly, even if their infiltration personnel are exposed, it will not easily make the high-level cosmic-level civilizations realize that their infiltration paths are from the internal channels of the cosmic-level civilization.

After all, when the three cosmic-level civilizations did not know the inside of the ancient civilizations, they would only think that the ancient civilizations would infiltrate their front-line troops from within the meteorite star sea, which was the most natural thing.

And with such a miscalculation, as long as the ancient civilizations deliberately misled and deviated the eyes of the cosmic-level civilizations from the right direction, then it would not be a problem to basically cover up their real infiltration path.

In order to prevent the high-level of the cosmic-level civilization from becoming aware of the secret infiltration route of the ancient civilization as much as possible after the infiltration personnel were exposed, the ancient civilization had prepared sufficient techniques to confuse the enemy before the operation was implemented, and perfected all the details as much as possible.

In terms of timing, the souls of ancient civilizations will delay their actions, try to avoid exposing and keeping a certain interval between the arrival time of the transgalactic spacecraft, rather than rushing to carry out infiltration operations once they arrive.

In terms of space, when the souls of ancient civilizations carry out infiltration operations, they will first move away from the storage warehouses where intergalactic spaceships transport materials, and then move to other battle star regions before infiltrating deep regions.

Basically, under the premise of maintaining the above principles, the more successful the infiltration of the soul bodies of the ancient civilizations, the later they are exposed, the more difficult it is to discover the secrets of their infiltration paths, and the path to the frontline troops of the cosmic-level civilization that the ancient civilizations have finally opened will not be easily destroyed.

On top of this basic goal, it is necessary to further release the soul virus, carry out control operations against front-line combat units, and so on.

In short, at this critical juncture of infiltrating the front-line troops of the cosmic-level civilization, the ancient civilization was cautious to tread on thin ice, lest this hard-won line be destroyed so easily.

If progress does not go well or even leads to failure at this important juncture, the ancient civilizations do not know what price they will have to pay to make up for it, so they can't help but worry.

It's just that the frontline combat units of the Meteorite Star Sea Galaxy are millions of light-years away, and the relevant ultra-long-range communication channels are not in the hands of the ancient civilizations, and the ancient civilizations do not even have the ability to listen to the relevant communication data, so even if the infiltration of the front-line troops has achieved initial success, it is an extremely long time cycle to receive news.

After all, the souls of the ancient civilizations going to the front line of the battle can be described as a "one-way ticket", and there is no internal cooperation in the frontline troops to cooperate with the corresponding actions of the souls of the ancient civilizations. In order to return the corresponding information, the infiltrators of the ancient civilization must first complete a series of personnel controls within the front-line troops.

At that time, no matter which communication channel is opened, whether it is through the ultra-long-range communication channel to let the relevant personnel send back the successful information according to the predetermined way of the ancient civilization, or through the channel of the return of the transgalactic spacecraft, as long as the relevant news can be transmitted back.

However, no matter what channel is used to send information back and forth, it is extremely difficult to achieve success, and it is not easy to complete. Because no matter what way to send back information, it is not possible to do it through one or two people, you have to control a series of people, and you have to go through multiple process transitions, which takes a lot of time.

No matter how much the high-level leaders of the ancient civilization wanted to receive relevant information in order to confirm whether their people had succeeded or not, they had to wait for a long process, and at the shortest it would take a year or two.
