Three days!

In just three days or so, the Iron Battlestars had already completed their first combat goal, completely destroying all the planets, buildings, and lives around the area they had arrived in after their ultra-long-range space-time jump.

During these three days, due to the emptiness of the defenses within the ancient civilization and the few resistance forces, the tens of millions of carrier ships under the jurisdiction of each Iron Battlestar were like entering a no-man's land, and after being launched from the Iron Battlestar, they launched a devastating attack in a radial shape towards all targets in all directions.

No target could withstand the slaughter and destruction of this massive and devastating legion, and everywhere the carrier force went, it was engulfed in soaring flames and magnificent explosions, all reduced to dust in the sky-rushing flames and unparalleled energy explosions.

Some of the ships of the Iron Battlestar jump directly to the most edge of the industrial area, sweeping away all the targets that can be destroyed, and some are pushing all the nearby industrial planets and industrial facilities step by step.

It took less than two days for all the targets that belonged to the attack category to be completely wiped out, and then the last day or so was the time for all the carriers to return to the Iron Battlestar.

Because all the surrounding targets that can be moved have been eliminated, and there is no obstacle to the existence of any obstacles, all the ship-carrying units of the Iron Battlestar can calmly return to the Iron Battlestar in accordance with the predetermined procedures, and the damage to the combat units under the jurisdiction of each Iron Battlestar under such an operation can be said to be minimal, and the number of warships lost by the Iron Battlestar troops on the side with the greatest loss is only more than a hundred ships, which can be said to be completely negligible compared to the results of the battle.

You must know that every attack target chosen by the ten Iron Battlestar troops of the three cosmic-level civilizations this time is an important industrial area within the ancient civilization, and in the complete industrial system of the ancient civilization, the importance of these industrial regions can be called pillars.

Among the ten targets attacked, according to the analysis of the data and information collected at the scene, the three cosmic-level civilizations can conclude that the scale of five of them may have more than doubled after reaching the hands of the ancient civilization, which is the result of the ancient civilization concentrating a large number of industrial production forces in the surrounding area, and the destruction of these five industrial bases is definitely a heavy blow to the ancient civilization, and I am afraid that the rupture will occur within a certain period of time in many production chains, and then affect the overall productivity of the ancient civilization to a greater extent。

Although the ancient civilization has a strong strength to compete with the three cosmic-level civilizations by integrating the resources of the three cosmic-level civilizations, many places are shallow in the end and have limited resources, and there is not much room for talent or equipment.

After all, the scope of each industrial production area has a range of more than ten light years, and a large number of talents, equipment, etc. gathered on the planet are probably the resources that the ancient civilization has integrated and gathered within the entire civilization, and some top talents can be called top experts in one aspect, and those who are slightly higher are often leaders in certain fields and pillar talents, and the operation and development of these important industrial areas require these top talents to pay a lot of effort to control and adjust.

Now these important industrial star fields have been completely wiped out at once, almost all of them have been destroyed with the destruction of the planet and the base, and even a large number of skilled workers have been wiped out together.

Even if the ancient civilization has a full set of materials of the industrial system, and the relevant technology and equipment of these destroyed important industrial areas are well preserved, but if there is a lack of core talents and leaders in related fields, those materials that only exist on the paper of archives are useless, and it is necessary to spend a lot of time and energy to re-select and train top talents in related fields before it is possible to start recovering these important industrial areas.

One can imagine how difficult it is to complete these tasks, even if the ancient civilization is now huge, with a population of hundreds of billions and countless experts in various fields, but it is not easy to fill these vacancies.

What's more, the ten Iron Battlestar troops of the three cosmic-level civilizations are not ready to stop there, they are still rampage all the way in the process of returning to escape from the ancient civilization, and all the important industrial areas along the ancient civilization have to be swept over and completely destroyed all the important industrial towns along the ancient civilization. Research center, this has brought a huge amount of losses to the ancient civilization, the scale of the loss suffered by the ancient civilization is getting bigger and bigger, and the gap in talent and equipment is increasing, and it has become more and more difficult to make up for it.

It's not that the Iron Battlestar troops of the three cosmic-level civilizations are not in a hurry to fight quickly at this time, and they want to fight wantonly within the territory of the ancient civilizations, and no longer care about the dangers of war that the Iron Battlestar needs to face.

It was really the first time that the three cosmic-level civilizations dispatched the Iron War Star to launch a counteroffensive against the ancient civilization was too rare, and the ancient civilization suddenly did not expect the internal emptiness to be powerful, and the three cosmic-level civilizations were unwilling to miss this opportunity, so it was possible to advance into the depths of the territory of the ancient civilization and strike at the important industrial zone in the tens of thousands of light-years area inside the territory of the ancient civilization.

With such a long jump distance, after consuming the opportunity to jump in ultra-long-range space-time that only has one chance a year, these Iron Battlestars can only enable the short-range space-time jump function with a shorter jump distance when they return home, so the time it takes to break out of the boundaries of ancient civilizations is naturally very expensive.

In such a return journey, it is conceivable that the dangers encountered by these Iron Battlestar troops will become more and more huge, and these ten Iron Battlestars will inevitably be attacked and intercepted by the fleets of ancient civilizations in the process of returning home. Such a thing can be said to be inevitable, even if the ancient civilization is slow to react in the process of these steel battle stars returning to the sea, the ancient civilization can also transfer waves of armed fleets.

And for the three cosmic-level civilizations, since this process of returning to the ship is indispensable to deal with the fleet attacks of the ancient civilizations, then it is natural that some corresponding combat results must be retrieved to be reasonable, and it is also for this reason that in the process of the return of the Iron Battlestar, those important areas within the ancient civilization have also become important targets for the Iron Battlestar troops to be easily eliminated.

The important industrial areas along the way back are naturally the preferred targets for the Iron Battlestar, and each Iron Battlestar will choose these important areas as the landing point of their short-range space-time jump when they return to the home, and attack the ancient civilization as much as possible while hurrying.

However, after many such actions, the ancient civilizations were naturally not stupid, and they often gathered heavy troops to stay around those important industrial areas, and launched a counterattack against the Iron Battlestar troops of the three cosmic-level civilizations.

After such an encounter, the Iron Battlestar forces of the three cosmic-level civilizations have changed their ways, no longer focusing on destroying important industrial areas along the way, but choosing to strike at a wider range of targets.

Along the way, those important educational star fields, scientific research star fields, important industrial centers, strategic material reserve centers, etc., ecological star fields where a large number of people gather, etc., have become the key targets of these steel battle star troops, no matter what kind of area as long as it is targeted by the steel battle star, it will completely become a dangerous area in the starry sky in just a few days.

The road back to the Iron Battlestar for thousands of light-years, the ravages are everywhere, even the planet and even the larger stars have been bombed into ruins by the Iron Battlestar troops, and large pieces of building wreckage cannot be found, and after a long time, the wreckage of each planet is connected to each other, and it has become a dangerous zone for interstellar traffic, and all the spaceships dare not go deep into it, which has caused great trouble to the transportation within the ancient civilization.

In this process of constantly making short jumps to evacuate, although the ten Iron Battlestars of the three cosmic-level civilizations were surrounded and intercepted by the ancient civilizations with all their might, they could not have much impact on these Iron Battlestar troops at all.

After all, each Iron Battlestar unit is a huge combat cluster including Iron Battlestar and tens of millions of carrier-carrying ships, and even if the ancient civilization wants to encircle and intercept the Iron Battlestar troops in a hurry, it is difficult to assemble a sufficient scale of combat troops in various locations in time under the emptiness of internal combat power.

What's more, the mobility of these Iron Battlestars is too strong, although they can't make ultra-long-range space-time jumps in a short period of time, but they can jump hundreds of light-years away every few days, and it's enough to get the Iron Battlestars out of any predicament.

Therefore, the return journey of ten steel battle star troops tens of thousands of light years away, although it can be called a long and dangerous road, but for these steel battle star troops, it is essentially just a hearty battle like a bamboo, and the battle damage of each steel battle star unit along the way back is not large, and it is not even as large as a battle loss in a wormhole passage defense line.

However, behind the casualties and losses of these Iron Battlestar troops, there were countless losses of the combat troops of the ancient civilizations, and every time the Iron Battlestars completed a short-range space-time jump along the way, they would cause a huge casualty loss to the ancient civilizations.

Even if the ancient civilization did not have enough troops to harass and attack the Iron Battlestar troops within the short-range space-time jump cooldown time of the Iron Battlestar troops, these Iron Battlestar troops would not be able to bear the loneliness and sweep the surrounding area, destroying everything that could be seen and valuable around them.

Whether it is a variety of ecological planets or space buildings, whatever kind of thing is passed by by the Iron Battlestar, it will inevitably be destroyed by the Iron Battlestar troops.

Although in essence, the people within the territory of the ancient civilization are all former citizens of the three cosmic-level civilizations, and it stands to reason that the troops of the three cosmic-level civilizations should not bear to be so ruthless, but the problem is that now the two sides are not only their masters, but more importantly, the contradictions between the two sides are completely irreconcilable.

In the past, the officers and soldiers of the three cosmic-level civilizations could not bear to attack the civilians within the ancient civilizations, but the result was that the three cosmic-level civilizations retreated step by step, and were about to be forced to a dead end.

What's more, although killing is easy to make people feel pity and unbearable, it refers to close-range combat, when they see the mutilated and terrifying corpses, people often realize how terrible the killing they have made, but at the level of the three cosmic-level civilizations, no matter how large-scale killing and destruction is, it is no longer a close-range battle.

The soldiers of the Iron Battlestar Force want to exterminate the population of a planet, and they don't need to witness their own killing, a star-destroying projectile is launched far away, destroying a planet from a distance of a few light years, and even the entire planet will be blown to pieces, not to mention the weak human body?

Therefore, the endless killing and destruction along the way, the officers and soldiers of the various Iron Fighting Star units have not even seen a drop of blood, as long as they overcome their own psychological barriers, such killing and destruction can even be said to have no psychological burden, and there are only various magnificent war scenes at a glance, but it is easy to expand their minds and have a feeling of relaxation.

In the eyes of the officers and soldiers of the Iron Battlestar Force, the small combat units surrounded by the ancient civilizations along the way are often more like cannon fodder who have thrown themselves into the net and killed themselves, and the Iron Battlestar Force can easily wipe them out with only a small part of their strength at the beginning.

However, the battle is not always so easy and comfortable, and the ancient civilization is not so easy to provoke, and the previous easy battles are just a careless fight of the ancient civilization in the final analysis, and the three cosmic-level civilizations have caught a flaw, and as time goes by, the ancient civilization has mobilized more and more powerful forces to contain the Iron Battlestar, so that the return road of the Iron Battlestar has begun to become more and more difficult.

Fortunately, although the Iron Battlestars of the three cosmic-level civilizations escaped in different directions, several Iron Battlestar troops under each cosmic-level civilization were constantly moving closer to each other and taking care of each other, which made the Iron Battlestar troops encounter more and more troops to chase and intercept them, but they all turned the danger into danger again and again, and successfully escaped through short-range space-time jumps.
