Of course, although the ancient civilization was optimistic that the three cosmic-level civilizations could be their best host civilizations, the three cosmic-level civilizations themselves were definitely not willing to be this so-called host civilization.

Every civilization itself has its own independent will since the day of its birth and is unwilling to be constrained by any external force. If it is not impossible, no civilization would want to see other civilizations dominate their own destiny and override their own.

Those ordinary interstellar civilizations can't resist the oppression of more powerful civilization forces, and they will only be subservient to others as a last resort, but a transcendent force like a cosmic-level civilization has been above thousands of civilizations since the day of its rise, and the high level of spirit is naturally conceivable.

It can be said that without crushing strength, no civilization can be looked down upon by them, let alone on an equal footing with them, or even on top of them to a certain extent.

If you want the three cosmic-level civilizations to admit that the ancient civilizations have the status of symbiosis and coexistence with them, it is even more difficult than ascending to the sky.

In particular, such a special form of civilization as the ancient civilization is even more notorious for other civilizations, and the bad reputation is obvious to all, just the souls of the ancient civilizations must eat the souls of intelligent beings to survive, which can already naturally cause the evil feelings of these civilizations.

The ancient civilization wanted to form a symbiotic relationship with the three cosmic-level civilizations and control the three cosmic-level civilizations in their own hands, which was definitely not as simple as a little bit, and they had to show absolute strength, grasp the life of the three cosmic-level civilizations, and even have the ability to completely destroy the three cosmic-level civilizations in one fell swoop.

In order to achieve this, there was only one way for the ancient civilizations, and that was to spread their soul viruses in advance.

In view of the experience of failure in the meteorite star sea, the ancient civilization has deeply understood that it is no longer enough to simply send some soul bodies to each planet and maintain the ability to infect and destroy the entire planet at any time.

Because the number of souls of ancient civilizations is too small, it is impossible to monitor the every move of the people inside the planet they are stationed on at any time, which makes the souls of ancient civilizations appear very passive.

Even if it is just the interior of a planet, the number of civilized citizens is innumerable, ranging from millions to tens of billions, and it is impossible for a population of this size to be monitored by just one ancient civilization soul body.

If these planetary personnel carry the souls of the ancient civilizations to make some preparations before the attack, it is absolutely impossible for the souls of the ancient civilizations to find them.

Therefore, if only the souls of ancient civilizations are only stationed on some planets as a deterrent, then it is often too late to start activating the soul virus infection when they encounter danger, and once the souls of ancient civilizations are eliminated, they will immediately come to naught.

In this way, even if the souls of the ancient civilizations seem to control the life and death of everyone on many planets, once those civilizations act in unison and destroy the souls of the ancient civilizations stationed on each planet at the same time, then the control of the ancient civilizations over this civilization may be destroyed overnight.

This is also the reason why the rule of ancient civilizations in the meteorite star sea suddenly collapsed.

In the past, when there was no soul detection equipment, the souls of ancient civilizations were very safe, because no one could detect their existence and determine their location, and they could launch a cleansing at any time, cleansing an entire planet, or even everyone in an entire civilization.

After confirming the deep control of the ancient civilizations over them, the controllers of those civilizations had to recognize the authority of the ancient civilizations and cooperate with the ancient civilizations in all aspects. Even for their own survival, they have to behave submissively.

However, with the advent and popularization of soul detection equipment, those civilizations have been able to discover the existence of the souls of ancient civilizations, so that the souls of ancient civilizations stationed in various planets are stationed on various planets, ready to carry out a major cleansing of various planets at any time, which is no longer enough.

Because with the exposure of the location of the soul body of the ancient civilization, they can no longer even guarantee their own safety, which is equivalent to putting themselves under the guns of the planet they are on at any time.

Although these soul bodies of ancient civilizations can spread the soul virus at any time, they have no room to use it now, and they may be killed at any time! In this way, no matter how terrible their soul virus is, it is useless, the soul virus cannot spread, and the threat is naturally much smaller, and those interstellar civilizations can completely endure a certain amount of casualties, and cancel the destruction of the soul bodies of ancient civilizations.

This is the case with the encounter in the meteorite star sea, those civilizations that have been controlled by the ancient civilization, their determination to regain their freedom and destiny is absolutely impossible to ignore, even if the citizens of many planets can even risk the extermination of more than half of the population to expel the soul body of the ancient civilization from their planet in order to get rid of the control of the ancient civilization, let alone the will of a civilization.

In order to regain the freedom of the entire civilization, I am afraid that any civilization will be willing to pay a huge price and take huge risks, unless the benefits that the ancient civilization can give them, enough to offset all the disadvantages they bring, so that they are willing to live with the ancient civilization!

Therefore, the means used by the ancient civilization to control the civilization under its command are now completely outdated and simply not enough. The new environment has put forward new requirements for the ancient civilizations, and if the ancient civilizations want to continue to survive and achieve more brilliant achievements, they must show more powerful control.

Fortunately, ancient civilizations have also had new solutions in this regard.

After thousands of years of development in the material world, the ancient civilization is not simply eating dry food without progress, on the contrary, the ancient civilization has also made a lot of achievements in many fields, such as the control of the soul virus, the ancient civilization has made some breakthroughs.

As before, as long as the soul virus is infected to a certain extent, then the infected object will definitely have relevant reactions, regardless of whether the soul virus is activated or not, after the infection level reaches a critical point, it will inevitably lead to the death or even corpse transformation of the infected citizens.

This is the reason why the ancient civilizations in the past did not dare to spread the soul virus at will and exercise deep control over the subordinate civilizations.

After the soul virus spreads too much, it will be completely insufficiently controlled, which will directly lead to the occurrence of many unexpected situations, which is very unfavorable to the deep control of a civilization.

Because no civilized citizen can live peacefully in an environment where his neighbors may turn dead and infect him at any time, and he does not care about commuting to and from work every day.

Therefore, in order to ensure that the civilization under their control can still have the motivation and potential to continue to develop, the ancient civilization can only maintain control over the subordinate civilization by sending soul bodies to various planets to garrison in the past.

As a result, this civilization control mode was directly collapsed in the meteorite star sea with the massive spread of soul body detection equipment by the earth's civilization.

But in fact, the ancient civilization has already made breakthroughs in the control of the soul virus, and some high-level members of the ancient civilization have already discovered some new soul virus control techniques, which can allow the soul virus to penetrate and erode normal life forms to a dose that is enough to kill instantly, but before the virus activity is activated, even citizens who are deeply infected with the soul virus will not have any physical discomfort.

Even because of the invasion of the soul virus, the quality of the soul of those intelligent lives has been improved, and it can also have great benefits to the human body to a certain extent, such as deafness and vision, refreshment, abundant mental strength, increased IQ, etc., which are a series of benefits brought by the improvement of the essence of the soul.

It's just that when this deep control ability over the soul virus was just excavated before, the individual quality requirements for the soul bodies of ancient civilizations were too high and could not meet the requirements of large-scale popularization.

Although the high-level leaders of the ancient civilization realized that the deep-level control ability of this soul virus had a major strategic use, they did not have the ability to use it on a large scale, or even change the control mode of the ancient civilization over the subordinate civilizations.

Later, after nearly a hundred years of continuous improvement, it was only recently that the high-level of the ancient civilization made a real breakthrough in the research and improvement of this ability, so that its use conditions and standards have been greatly reduced, and every qualified soul body of the ancient civilization can master this ability after simple training.

However, it is a pity that by the time this new strategic technology is truly thoroughly studied, the rule of the ancient civilization in the meteorite star sea galaxy will already be in jeopardy and fall apart, and it is impossible to successfully perform it in the meteorite star sea.

Fortunately, although this strategic skill was born one step later, it obviously still has a huge space for display among the three cosmic-level civilizations.

The high-level leaders of the ancient civilization have determined to fully spread this new skill within the civilization, so that every soul body can master the new soul virus control technique, and when the three cosmic-level civilizations are fully invaded, they will completely change the control mode of the ancient civilization over the civilizations under their command.

In the past, in order to ensure the control of the civilizations under their command, the ancient civilizations had to work hard to send soul bodies to be stationed on planets.

But after all the souls of ancient civilizations have mastered this soul virus control skill, they will spread the soul virus on a large scale in an all-round way, ensuring that the soul virus directly penetrates into the depths of the souls of every cosmic-level civilization citizen, which is equivalent to installing a button in the depths of the souls of every cosmic-level civilization, and the ancient civilizations with the authority can destroy all the lives of the entire cosmic-level civilization at any time, and no one can be spared as the destruction signal is transmitted.

You can also designate a certain planet, a certain area, or even a certain person who is completely killed in an instant after receiving the virus activation signal, which can be said to strengthen the control of the ancient civilization over the civilization under its command to the greatest extent, and will never be easily unshackled by a certain civilization and break free from the control of the ancient civilization.

In this way, even if it is the three cosmic-level civilizations, as long as they are deeply infiltrated by the ancient civilizations, they will inevitably be controlled in the hands of the ancient civilizations, and this control is absolutely indestructible, as long as the three cosmic-level civilizations are not willing to die together with the ancient civilizations, then the rule of the ancient civilizations over the three cosmic-level civilizations will never be like the meteorite star sea, which will completely collapse in minutes, and the ancient civilizations have full self-confidence.

Because once the soul virus is planted, it is something that penetrates deep into the soul, and it cannot be changed at all, as long as the penetration deepens year by year, the citizens of each generation of cosmic-level civilization cannot get rid of the control of the ancient civilization, which can never be changed.

In fact, if it weren't for the infiltration and diffusion of the soul virus, there were many restrictions on it, and if it didn't spread out casually and be able to infect a large area at once, the ancient civilizations would even want to control the earth civilization with all their might.

Imagine that the earth civilization first gave the ancient civilization a black hand, and the ancient civilization was defeated, and as a result, the ancient civilization hit backhand and controlled the entire earth civilization in turn, which is simply a greater and more dazzling achievement for the ancient civilization than controlling a universe-level civilization, and it can be regarded as picking up the lost face of the ancient civilization.

It's a pity that even if the earth civilization has soul body detection equipment installed in every ship, the ancient civilization can't penetrate the interior of the earth civilization at all, and it is impossible to talk about further controlling the earth civilization, so that the ancient civilization has to leave its homeland and go back to the three cosmic-level civilizations to work hard after mastering the new soul virus control technology.

Although with the new soul virus control technology, even if it is to open up a new world among the three cosmic-level civilizations, the difficulty will inevitably be reduced a lot, but the difficulty of expanding the territory still exists after all.

There is nothing to mess with in a cosmic-level civilization, and people's technology is too advanced, which will bring a lot of unexpected risks.

The ancient civilization wanted to control the three cosmic-level civilizations, and it was inevitable to encounter a lot of setbacks during the period, and even under the detection of the soul detection equipment of the ancient civilization, it was inevitable to lose a lot of manpower, which was a predictable thing. However, if the ancient civilization wanted to gain its own living space, this action was an indispensable step.

Moreover, drawing on the various gains and losses of the ancient civilization that once ruled in the meteorite star sea, the ancient civilization has also been prepared to carry out many changes, as much as possible to maintain the symbiotic relationship between the three cosmic-level civilizations, and make the relationship between the two too rigid and hostile as much as possible, so that the ancient civilization can continue its rule to a longer future, so as not to tear its face with the civilization under its command at every turn.
