For the secrecy of this hole card, the ancient civilization side did a very solid job. Only a very small number of high-ranking personnel knew about this secret, and even the vast majority of the middle and high-ranking officials of the fleet were unaware.

The reason for the implementation of such a strict secrecy system is that the ancient civilization is to take it by surprise, in order to set off this hole card in one fell swoop at the most appropriate moment, and create the greatest results, so it is not necessary to know the relevant details, and the ancient civilization is all isolated from the scope of insiders.

Even the leaders and leader-level figures of the rebel forces within the many cosmic-level civilizations under the command of the ancient civilizations had a good understanding of this core secret until the battle plan was implemented to the end, and the ancient civilizations only informed the relevant details when the troops of the two camps were about to start, and at this time, it was only a few days before the time to open this hole card.

At this time, even if the relevant secrets are leaked, in fact, the impact will not be too great, because even if the three cosmic-level civilizations have learned some relevant information from some channels, it is simply impossible to temporarily make up for the loopholes at the moment when the war is about to start.

But even so, the ancient civilization side did not have any intention of divulging the slightest bit of relevant information, after all, once the relevant secrets were leaked, even if the cosmic-level civilization side could not fundamentally change their disadvantages, but temporary measures were taken to change the battlefield pattern as much as possible and reduce part of the losses of the cosmic-level civilization side as much as possible, which is still quite possible.

It is not even possible to say that if some top-level scientists really emerge within the cosmic-level civilization, after learning the relevant secrets of the ancient civilization, they can come up with a reasonable operation to avoid combat risks in the shortest possible time, although this possibility is not great, but it is not absolutely impossible.

For no reason, the ancient civilization was naturally unwilling to take any risks, so even when disclosing relevant confidential information to some of the top power leaders on the side of the ancient civilization, the ancient civilization had a certain amount of concealment.

For those leaders of subordinate forces who are outside the battlefield and waiting for the feedback of combat news in the territory of the ancient civilization, the ancient civilization simply disclosed to them that the ancient civilization has some hidden hole cards that are enough to flip the battlefield pattern, so as to appease people's minds and enhance the confidence of these subordinate forces in the ancient civilization, but the specific details about this hole card, the ancient civilization did not disclose it.

After all, these subordinate forces sitting in the rear are just a reassuring pill for them, and even if the specific confidential information is revealed to them, it has no practical significance, and maybe even a bad news will be transmitted to the ears and eyes of the three cosmic-level civilizations through those channels, and the ancient civilizations will naturally not do this kind of life-threatening matter.

In the battlefields of each core star field, some of the information selectively disclosed by the ancient civilization to the high-level of those combat command fleets is a little fuller, and even roughly points out the specific nature of this hole card, but some of the core data, before it really needs to use this hole card, the ancient civilization still has not really revealed it.

When the ancient civilization decides to activate this hole card, it is necessary to pass the relevant data to the whole army through the secret channel of the fleet as soon as possible, and then activate it in accordance with the instructions, and implement the action according to the plan arranged by the ancient civilization in advance!

As long as the officers and soldiers of these front-line troops honestly act in accordance with the plans of the ancient civilization, then this war can be said to have been locked in advance in the eyes of the ancient civilization.

And under such careful planning of the ancient civilization, the ancient civilization also believed that this war would never deviate from the predetermined route of the plan, and this war was indeed in sight.

Although all this seems to be easy to come by, such a result can really be regarded as living up to the layout of the ancient civilization nearly a thousand years in advance in the eyes of the ancient civilization.

The ancient civilizations had tried to activate some hidden layouts countless times before, but in order to get better results, they finally endured it.

Now that he has finally played the hole cards accumulated for many years, in order to achieve a subversive effect in this important war, it is natural to have such a huge effect.

However, to be able to accumulate such a deadly hole card, this is not a simple matter for the ancient civilization, for which the ancient civilization has used almost all its hidden power within the three cosmic-level civilizations, and even in order to complete the corresponding layout, many of the ancient civilization's deeply buried chess pieces have left many well-documented clues in some actions.

Before this war, the three cosmic-level civilizations were not aware of the problems in the relevant aspects, and the clues left by these chess pieces naturally did not arouse the suspicion of the cosmic-level civilizations, but after this war, where would the three cosmic-level civilizations not understand what was going on, and then these clues left behind would inevitably lead to the complete collapse of this secret network painstakingly operated by the ancient civilizations, and all the relevant personnel would face a stormy sweep of the cosmic-level civilizations.

At that time, it can be said that the power network layout formed by the ancient civilization within the three cosmic-level civilizations over the years will also be completely destroyed, even if there are still some residual sporadic forces in the ancient civilization, it is completely impossible to launch a similar action again. Without thousands of years of operation, it is impossible for the ancient civilization's power network within the three cosmic-level civilizations to recover to a similar extent.

At that time, with the help of these remnant power networks, it would be good for the ancient civilization to be able to detect some reliable news within the three cosmic-level civilizations, but other more influential actions could not be counted on at all, and such sacrifices could not be said to be huge, but as long as they could win the war in front of them, then all these sacrifices would be worth it for the ancient civilizations.

However, it is precisely because of the huge power network that the ancient civilization had before that lurked within the three cosmic-level civilizations that the ancient civilizations were able to clearly know that just as the ancient civilizations had nails buried within the three cosmic-level civilizations, in fact, among the forces on the side of the ancient civilizations, there were also many chess pieces that the three cosmic-level civilizations had carefully arranged.

As far as the ancient civilization knows, there are even some cosmic-level civilizations that have laid out chess pieces that have risen to high positions, climbing to the top of the ranks second only to the leader among some of the subordinate forces of the ancient civilization.

It's just that the power network that the ancient civilization has been concentrating on for many years, under the intentional control and adjustment of the ancient civilization, the main forces are not concentrated in the intelligence department of the universe-level civilization, which leads to the fact that although the ancient civilization has obtained some faint rumors, the specific list of spies arranged by the three major universe-level civilizations, the ancient civilization has not obtained much information, at most it only knows the information of some low-level spies, which is of no great use.

These spies are all in one-line contact with the intelligence personnel within the cosmic-level civilization, even if the ancient civilization wants to follow the vine and uproot the potential spy network inside, there is no room for operation, so the ancient civilization has no idea of doing any similar spy purge in its own sphere of influence, it is useless at all. At most, all the spies that have been exposed are punished with capital punishment, implicating their relatives and children, etc., and giving others the greatest deterrence, and the ancient civilization has not done anything superfluous.

It is really too low for the three cosmic-level civilizations to place spies inside the ancient civilizations.

After all, the citizens of the three cosmic-level civilizations have a strong fear and centripetal force for the ruling class of the three cosmic-level civilizations, and the orthodox power of the cosmic civilization is very irresistible for the citizens of any cosmic civilization, which the ancient civilizations are completely incomparable.

Although the ancient civilization was able to stir up the storm and finally tear a huge territory from within the three cosmic-level civilizations, this result depended to a large extent on the threat and coercion of the ancient civilization, and even the ancient civilization itself did not believe in this to say that everyone was loyal to the ancient civilization.

It can be said that almost all of the forces under his command are composed of citizens of cosmic-level civilizations, and there are still a considerable number of people who are orthodox and have a little idea of leaving a way back, and the ability of the three cosmic-level civilizations to plant spies within the ancient civilizations is naturally extremely powerful, and many of the forces that eventually defected to the side of the ancient civilization themselves imply a great element of espionage, which the ancient civilization will naturally not be unclear about.

But in order to expand to the greatest extent, in order to complete the final control of the three cosmic-level civilizations, the ancient civilization had to turn a blind eye many times, and it was impossible to be ruthless against some defecting forces without iron-like evidence, otherwise the many forces under the command of the ancient civilization would not be in danger for everyone?

Anyway, for the ancient civilization, since you have fallen to my side, the soul virus will naturally slowly infect you, since this thief ship is on and wants to go down, it is impossible, sometimes even if you know that some people are suspected of spies, the ancient civilization does not matter at all.

So as long as important secrets are not leaked, these spies or other ancient civilizations don't care at all, the core secrets of the ancient civilizations are not among these subordinate forces, and no matter how many spies there are in the subordinate forces, they may not be able to play any role.

Even for the ancient civilizations, even if some people come up with ironclad evidence now, and can prove that the commanders of certain combat fleets are spies arranged by the three cosmic-level civilizations, the high-level leaders of the ancient civilizations are not surprised at all. There are spies in officials at this level, which is simply too normal within the sphere of influence of the ancient civilization, as long as these spies are not blatantly engaged in things and committed the taboos of the ancient civilization, the ancient civilization can even turn a blind eye and act as ignoring.

It is precisely because there is such a deep-rooted hidden danger of espionage within the ancient civilization, so in this major military operation, the ancient civilization adopted the strictest secrecy procedures, and before the hole cards were revealed, there was not even a cosmic-level civilized citizen who had mastered comprehensive information, so as to ensure the security of secrets to the greatest extent.

Even those members of the forces belonging to the ancient civilization who have learned the confidential information revealed by the ancient civilization, the ancient civilization has also sent a special ancient civilization soul body to monitor it, beware of the possibility of all information leaking.

The number of these personnel is extremely limited, and most of them have been temporarily gathered together, and the ancient civilization has temporarily monitored them, which can be said to be not difficult at all, even if these high-level personnel are a little suspected of spying in normal times, the ancient civilization can also turn a blind eye, in order to unite all the forces that can be united, and complete the integration of the forces of all cosmic-level civilizations.

But at this critical juncture, the ancient civilization did not hesitate to kill, and anyone who dared to leak secrets, the ancient civilization had already been warned, and it must be disposed of as soon as possible, leaving no room for anything.

Therefore, even if there are some spies such as the commander-in-chief of the fleet, they have obviously obtained important confidential information, but as long as they still want to live, they will not dare to act rashly in the slightest.

What's more, the ancient civilizations were prepared in advance for the leakage of any person, even if they wanted to find an opportunity to pass on the information, there was no chance at all, and even once they made a rash move, they would directly lose their lives, and they dared to commit crimes against the wind under such a strong threat, to be honest, although there are many spies in the three cosmic-level civilizations, there are very few spies with such high-quality spies.

The more powerful a person is, the more greedy he is for life and fear of death, and the same is true for citizens of cosmic-level civilizations. They were already in high positions on the side of the ancient civilizations, and the loyalty of these spies was already quite questionable, and expecting them to be able to sacrifice their lives to fulfill their obligations as spies was nothing more than a luxury in many cases.

At least after receiving the relevant confidential information disclosed by the ancient civilization, the ancient civilization clearly knew that some important people were suspected of being a major espionage, but from beginning to end, these spy suspects were more than normal, without the slightest appearance of wanting to do something, and there was no suspicious small action.

From here, it can be seen that the policy of appeasement and nurturing traitors in ancient civilization to a certain extent has finally achieved certain results, and these forces have inevitably slowly integrated into the system of ancient civilization, and slowly spies will no longer be spies.
