However, the low profile of the ancient civilization did not last long.

As more and more souls of ancient civilizations converged, they cobbled together an increasingly large army of infected souls, and with a sufficient number of souls of ancient civilizations to preside over the overall situation, the situation in the immigrant star field had to change once again.

Originally, under the fact that various interstellar civilizations had squeezed out the bone marrow and spent all their blood to piece together and build, those planets located on the migration routes of the ancient civilization's soul body army had established a powerful planetary defense system that was enough for the ancient civilization's army to easily eat, which allowed many people on the planet to successfully gain a glimmer of life under the ravages of the ancient civilization's migration army.

However, after the number of the soul body army of the ancient civilization reached a certain scale, an invisible change appeared, and it soon became a killer move of the ancient civilization, which was valued by the soul body of many ancient civilizations and used on many planets, so that the people on many planets were caught off guard and buried in the hands of the ancient civilization.

At the beginning, the various interstellar civilizations have not yet discovered this new change, although everyone has done their best to build a new planetary defense system, squeezing out the wallets of the people and governments of the entire planet, and even so, it is not able to block the attacks of the ancient civilizations 100%, and from time to time there are still some planets that are finally broken by the ancient civilizations, and the people on the planet are all harvested and wiped out.

But even so, the people of the planets are confident that the new planetary defense system is indeed safe and effective enough.

At least with this newly upgraded planetary defense system, there are still many planets that have survived in the end, and without the protection of this planetary defense system, all planets that have been attacked by the soul army of ancient civilizations can almost be said to be 100% destroyed.

Therefore, even under the ravages of ancient civilizations, some planets will be destroyed by ancient civilizations from time to time, but many interstellar civilizations still trust the effectiveness of this planet's defense system very much, believing that it is enough to offset the threat of ancient civilizations to the greatest extent.

However, as more and more changes in ancient civilizations were detected by many interstellar civilizations, all the interstellar civilizations of the meteorite star sea sensed that something was wrong.

Since the new planetary defense system was discovered by many civilizations, the soul armies of ancient civilizations have suffered countless setbacks, and they have been bloodied in front of countless planets, so that in order to avoid suffering greater losses, the soul armies of ancient civilizations have greatly reduced the number of attacks on the planets along the way, and the number of times that the people inside the entire planet have been completely harvested is even rarer.

This situation has been going on for a long time, and many interstellar civilizations have not even heard of the soul armies of ancient civilizations carrying out continuous planet-destroying actions for a long time.

But recently, on the migration routes of various ancient civilizations in the immigrant star field, there have been a series of acts of destruction, and many ancient civilizations have been completely destroyed by the ancient civilization army on the migration route of several planets, and after the migration of the army, according to the results of some interstellar civilization detection, not to mention the people of the interstellar civilization on these planets, even living creatures larger than rats are almost impossible to find.

At the beginning, many interstellar civilizations thought that this was just an accidental situation, perhaps because the soul body army of the ancient civilization had been frustrated too many times, but now that the army has gathered together and has enough capital, in order to boost the momentum, it deliberately implements some destructive actions to boost the morale and spirit of the soul body of the ancient civilization.

If it's just that, then although a large number of planets have been devastated, it is nothing for the entire immigrant star field, after all, this kind of action of slapping a swollen face and making money is not possible for the ancient civilization to implement endlessly, and after the ancient civilization can not support this huge war loss, it will naturally have to stop.

But contrary to the expectations of many interstellar civilizations, the soul body army of those ancient civilizations is not afraid of swollen faces and fat people, under the attack of their armies, the destroyed planets are one after another, each of which is equipped with an upgraded planetary defense system, which has a strong killing ability to the soul body army of ancient civilizations, it stands to reason that even if the various migration troops of the ancient civilization are gathered together, they should lose their troops and fight again after fighting so many tough battles in a row, but the ancient civilization actually has no signs of being able to fight again, and still shows a strong desire to attackThe planets that the armies migrated through were all destroyed at the hands of these migratory armies.

After discovering this situation, many interstellar civilizations in the immigrant star field couldn't sit still, this situation is obviously wrong, if it is a military operation with huge losses, there is no reason why the migratory army of ancient civilizations can hold on again and again, and the combat mood is so high, there must be something new that has appeared and they did not notice it at the first time.

Various interstellar civilizations have begun to work from various angles, trying to discover the reason why the ancient civilizations suddenly behaved so bravely.

When the soul armies of ancient civilizations attacked various planets before, all the data and intelligence during the battle were not a secret to many interstellar civilizations, because even if the new planetary defense system had strong firepower and actual combat value, the power of one planet alone was not enough to deal with all kinds of changes on the battlefield.

In the past, when dealing with the attacks of ancient civilizations, there were a large number of civilizations providing various related services to the attacked planets, and a large part of them were battlefield information processing services.

Every time a planet is attacked by an ancient civilization, there are at least ten or eight faster-than-light warships in the surrounding area of the planet to provide real-time combat support for the attacking planet, and a large number of combat personnel constantly adjust the combat instructions to maximize the combat performance of the planet's defense system.

And the civilization to which these warships belong has always retained a lot of battlefield engagement information.

There have been quite a few interstellar civilizations that have sensed that the momentum of the ancient civilizations is wrong, and they feel that there seem to be some abnormal situations on the battlefield, which may be the key to the ancient civilizations repeatedly destroying various planets, but only relying on the strength of a small number of interstellar civilizations themselves, they cannot detect those extremely hidden battlefield anomalies in the massive data.

Now many interstellar civilizations are aware of the abnormality of the situation, they work together, put together a large amount of battlefield data, and carefully compare with the previous battlefield information, after spending a huge amount of energy and computing resources, these interstellar civilizations finally found out where the situation is wrong.

The time of the battle has become shorter, and those planets that have been attacked by the army of souls of ancient civilizations have significantly shortened their resistance time, and many planets have not even been able to hold out for too long under the protection of the new planetary defense system, and they will soon be lost to the attack of ancient civilizations, and the entire planet will soon fall.

This situation has actually been discovered by many interstellar civilizations that have immigrated to the star field before, but it did not attract much attention at first, because now the soul army of the ancient civilization has swelled very much after gathering various migration troops, and many civilizations initially thought that the reason why these planets were quickly broken through the defense was only because the number of armies dispatched by the ancient civilization was too large.

But now, after in-depth analysis and research, these interstellar civilizations have found that the situation is far from as simple as they thought at the beginning.

After an in-depth search of the social situation inside the lost planets, many interstellar civilizations have found that there are some anomalies inside the planets before the defense system of these planets is completely broken.

A large number of people are suspected of being infected by the soul virus, and there are many turbulent factors in the entire social order, and countless signs show that before the planetary defense system fails, the soul virus of the ancient civilization has begun to rage in the planet, which is the fundamental reason why those planets can't hold on and are easily wiped out by the army of the ancient civilization.

At first glance, this situation seems to have a hole in the planet's defense system, which has been infiltrated in advance by the soul body army of ancient civilizations.

If this is the case, then it is no wonder that ancient civilizations are re-energizing.

The reduction of the time in the phase of combat means that the casualties of the ancient civilization have been greatly reduced, and the gains after the victory of the war remain unchanged, and the original bloody war has become profitable again, which is no wonder that the combat enthusiasm of the ancient civilization has not been reduced in the slightest during this time.

If this problem cannot be completely solved, it will be a huge disaster for many interstellar civilizations in the meteorite star sea, and countless interstellar civilizations will be affected.

In view of the seriousness of this problem, many interstellar civilizations have contacted the Earth civilization for the first time and asked the Earth civilization to send a professional investigation team to investigate the truth.

There are not many civilizations that believe in the suspicion that the planetary defense system may have huge potential vulnerabilities, because this so-called new planetary defense system is actually essentially a powerful firepower projection system, and its unimaginable attack firepower is enough to cover every inch of space outside the planet's atmosphere, and there can be no real loopholes at all.

And the real core and soul of this planetary defense system is actually just a planet-level soul body detection equipment sold by the Earth civilization to the outside world.

Although the accuracy of this equipment is not high, the range detection ability is extremely powerful, only one infected soul body per square kilometer can be accurately detected, and a large number of soul bodies have never slipped through the net when they enter the detection range.

Under the monitoring and prevention of this powerful soul body detection equipment, it cannot be said that there are no infected soul bodies that can penetrate into the interior of the planet, but it is definitely not enough to set off too big waves inside the planet, after all, those planets that face the invasion of the soul body army of ancient civilizations have far more resistance to war than the defense system outside the planet, and there is also a strict order and perfect response measures on the surface of the planet, and a small number of infected souls are simply not enough to endanger the safety of the planet.

Countless times relying on the soul body detection equipment of the earth civilization has won wars with the ancient civilization army, and many interstellar civilizations that have immigrated to the star field have strong confidence in the soul body detection equipment of the earth civilization, and no one thinks that under the monitoring of this equipment, there will be any large-scale infected soul body enough to penetrate the interior of the planet.

Therefore, there must be a deeper reason for the sudden sexual activity of the ancient civilization, but what is the reason is that ordinary interstellar civilizations can detect the truth, and they can only have a chance to solve this crisis with the help of the power of the earth civilization.

Fortunately, the earth civilization seemed to be very easy to talk this time, unlike the previous refusal of some interstellar civilizations who tried to buy a higher level of soul body detection equipment, this time the earth civilization quickly sent a professional investigation team to the front line of the operation, and deeply investigated the internal reasons for the sudden change of the ancient civilization.

Compared with many interstellar civilizations that are blind to the soul body level, the cultivators of the earth civilization have a deep understanding of the soul bodies of the ancient civilizations, I don't know how many times.

Under the investigation of the professionals of the earth's civilization, the truth of the situation was soon revealed.

In fact, the situation is much more serious than what the star civilizations who immigrated to the star field think, the souls of the ancient civilizations did not find the loopholes in the planetary defense system, they directly mastered the ability to inflict a devastating blow on the entire planet through a layer of planetary defense system.

The souls of those infected souls contain a large number of soul viruses, and this soul virus is a terrible virus that is deadly enough for individuals of other civilized races, and after a certain dose of infection, the soul of the whole person is completely deteriorated and dies. But for the soul bodies of ancient civilizations, these soul viruses are just a kind of pure soul essence, a special structure of soul power, which can be manipulated and controlled by the soul bodies of ancient civilizations in a variety of ways.

When the army of ancient civilization launched an attack on various planets, it was attacked by the planetary defense system, and countless infected soul bodies were broken into fine pieces, and the concentration of soul viruses contained in the space was unprecedentedly rich, under the control of a large number of ancient civilization soul bodies, this massive soul virus was directly infused into the interior of the planet, quickly infiltrating and infecting many people, resulting in rapid chaos in the internal order of those planets, and the defense of the entire planet was self-defeating, which is the fundamental reason why the ancient civilization has won many battles and suddenly become active in recent times。
