There are many production lines, many high-precision production equipment, and a large number of various scientific and technological materials, which can process and produce a large number of raw materials, components, and important equipment.

Although limited to the limited internal space, the many production equipment integrated inside the Iron Battlestar is only a small part of the entire production system of the ancient scientific and technological civilization, and it is far from enough to produce all the scientific products of the ancient civilization, but at least the vast majority of the equipment and parts used to maintain the Iron Battlestar's own needs can be produced by the Iron Battlestar.

It is precisely because most of the necessary equipment can be self-sufficient, that the Iron Battlestar can resist the erosion of time, and has maintained its most basic performance and strength through continuous maintenance and even replacement of a large number of parts for millions of years.

Therefore, in this case, the top management of the Earth Fleet believes that if they continue to dig deep into the previous attack target, even if some important equipment and lines of the Iron Battlestar are damaged, the Iron Battlestar has a great possibility and can repair the damaged part of the facilities, so that the attack value of the old target will naturally be reduced too much.

The target that can be repaired, for the Iron Battlestar, is nothing more than consuming some time, energy, and materials, and sooner or later it can be repaired again, and there is little point in attacking it.

The goal of the superlight cannon is different, the earth civilization is very sure that once the steel battle star is lost, it really can't be made up, because if you want to produce the superlight cannon, the scale of the relevant production line, the number of supporting factories, etc., is an incomparably huge number, and the earth civilization is only used to produce several core equipment components for the production of the superlight cannon, and the related material processing, processing and production supporting plants are enough to fill the space of a star system.

Even if the ancient civilization was technologically advanced, the production process of the faster-than-light cannon was simplified, and even miniaturized to the greatest extent, it was still an incomparably large production system, which needed to occupy a lot of space for placement, and the Iron Battlestar would be difficult to afford anyway.

So, rather than choosing a target that may not be important, the Earth Fleet is more inclined to destroy these non-replicable tachyon artillery installations.

After clarifying the new combat target, the Earth Fleet quickly let go of its hands and feet, and launched a counterattack as soon as the ship gun was fully charged against the faster-than-light gun targets exposed in the previous several attack waves of the Iron Battlestar.

Although the Earth Fleet's superluminal cannon is not as fast as the Iron Battlestar's charging speed, strong attack strength, and strong defense, the Earth Fleet also has its own advantages, at least the Earth Fleet can launch a larger attack in one attack wave, and the position of the Iron Battlestar's ultralight cannon is relatively fixed, and the Earth Fleet can be described as a dozen and one accurate.

If the Iron Battlestar's faster-than-light cannon hadn't shrunk into the underground defensive fortress as soon as the attack was completed, it would still be difficult to say which side would have achieved a greater advantage after the attacks of both sides reached the target area. At least the Earth Fleet believes that the probability of its own losses being smaller is relatively greater, after all, the Earth Fleet is too mobile, and it is almost unimaginable for Iron Battlestar to complete long-range sniping.

The only thing the Earth Fleet is worried about is that if the Iron Battlestar's faster-than-light cannons all act as shrinking turtles after completing the attack, then the Earth Fleet will have to sit on wax, and the battle situation will return to the original point.

The outermost alloy armor layer of the Steel Battlestar, which is twenty kilometers thick, how much firepower and ammunition does the Earth Fleet have to consume to break through the defense?

Fortunately, in the process of charging the Earth Fleet's naval guns, a sporadic discovery made the Earth Fleet let go of the fear that the Iron Battlestar would completely act as a shrinking turtle.

Some of the superluminal cannons that were exposed in the previous attack waves also occasionally participated in the attack when the Iron Battlestar carried out other rounds of salvo attacks, although the number of such superluminal cannons that participated in the attack many times was not large, and there were only a few dozen of them together, but at least this shows that the Iron Battlestar did not put all the faster-than-light cannons into the underground bunker fortress after the completion of a round of attacks, which left a glimmer of possibility for the attack of the Earth Fleet to be able to gain something.

However, it is understandable that Iron Battlestar chose to do so.

It's not that Iron Battlestar is unwilling to shrink all these faster-than-light cannons back into the underground fortress after all the faster-than-light cannons have attacked, it's just a waste of resources, and the situation is not allowed.

For each faster-than-light cannon that completes the attack, Iron Battlestar will protect it as soon as possible, sending a large number of sub-lightspeed ships to form a three-dimensional surround flesh shield shield to protect the safety of these faster-than-light cannons.

In fact, after these faster-than-light cannons completed an attack, the Earth fleet did everything they could to shrink them back into the underground bunker fortress as soon as possible, and then used a large number of sub-light ships as meat shield bunkers, which was undoubtedly a seemingly redundant move.

But for Iron Battlestar, this is by no means a useless move.

You must know that the superluminal cannons loaded on the Iron Battlestar are all huge and large superluminal attack weapons, in order to ensure the effectiveness and lethality of the attack, the blocks of these superluminal cannons are like a small mountain, far from being as small as the naval guns of the Earth Fleet.

This leads to the fact that when these superlight cannons are contracted and stretched, the speed is relatively slow, a set of superlight cannons want to transfer from the combat form to the hidden form of the bunker, to say the least, it will take more than ten minutes, and the depth of descent at this time is quite limited, even if it enters the inside of the bunker, the thickness of the alloy deck above the head is only about 100 meters, which is completely enough under normal circumstances, usually with multi-layer energy shield protection, escape into the cover with a thickness of more than 100 meters and stretch out, this safety can be said to be very guaranteed。

The problem is that in the current battlefield environment, it is not enough to only escape to a depth of 100 meters underground, and if you want to escape into a deeper layer of bunker, it will take a long time, often a few hours of tossing.

So in order to protect the safety of these faster-than-light guns, Iron Battlestar had to gather a large number of sub-lightspeed ships from the surrounding area to act as shields to provide protection for the faster-than-light guns.

It's just that in this way, the situation is also very embarrassing, to protect a superlight cannon, it is necessary to mobilize a large number of sub-light ships around, and the protection of other positions of the Iron Battlestar will naturally be weakened, only in the areas where the surrounding sub-light ships have not been mobilized, the Iron Battlestar can re-raise the superlight cannon and carry out a charging attack on the Earth fleet.

Therefore, the number of sub-light speed ships has become a key factor restricting how many faster-than-light guns Iron Battlestar can use at this moment.

In order to balance the needs of all sides, so as not to take care of this side and not take care of the other, the number of faster-than-light cannons that Iron Battlestar can use is limited, and some faster-than-light cannons have to continue to fight even after completing a round of attacks, and continue to recharge under the protection of the meat shields of many sub-lightspeed ships.

However, the Iron Battlestar is also very cunning, in order to minimize the loss of faster-than-light ships as much as possible, a faster-than-light cannon is only ready to carry out two rounds of attacks, after completing two rounds of attacks, when these faster-than-light cannons shrink into the deep underground bunker, and will not be threatened by the artillery fire of the Earth fleet, it will release the corresponding sub-lightspeed spaceship and activate other faster-than-light cannons to attack.

In this way, the security of these non-replenishable faster-than-light attack weapons can undoubtedly be guaranteed to the greatest extent.

Time flies on the battlefield, and just after the Earth Fleet completed the first round of salvo attacks on the Iron Battlestar's superluminal gun, the first wave of the Iron Battlestar's attack on the Earth Fleet also quickly arrived in the area where the Earth Fleet is located.

At this moment, all the officers and men of the Earth Fleet sweated fiercely, and all the spaceships quickly maneuvered and changed direction in their predetermined orbits according to the predetermined plan, dodging every attack of the Iron Battlestar as much as possible.

Although the Earth Fleet in front of him has no experience of fighting with the Iron Battlestar before, the Earth civilization has already had many contacts with the Iron Battlestar after all, and there are a large number of Earth ships that have summarized a lot of relevant information.

Therefore, the officers and soldiers of the Earth Fleet present at this time know very clearly that the strength of the Iron Battlestar should not be underestimated, and a large number of Earth ships have been destroyed in the hands of the Iron Battlestar, and now although the Iron Battlestar only has a thousand faster-than-light attacks, it is not good, and it may also bring a lot of casualties to the Earth Fleet.

The key is that there are a large number of jamming signals attached to the Iron Battlestar, and the Earth Fleet failed to capture the ballistic trajectory of the Iron Battlestar's faster-than-light attack in the first time, and after the faster-than-light attack was excited, the Earth Fleet could not capture the relevant information of these terrible faster-than-light attacks, which led to the Earth Fleet not knowing the path of the relevant attack, and all the evasion routes also carried a lot of uncertainties.

However, the attack algorithm of the Iron Battlestar is quite sharp, and through a large number of directional attack path matching, the Iron Battlestar can always create the maximum possible kill, which makes the officers and soldiers of the Earth Fleet have to be a little nervous.

Fortunately, the Earth Fleet was quite lucky this time, the estimated attack time had passed, and no ships suffered losses, and at the same time, by analyzing the traces of changes in the surrounding interstellar matter, the Earth Fleet also calculated a large number of path data of the first round of attacks of the Steel Battlestar, which was transmitted to the rear fleet, and could also avoid secondary damage to the Earth Fleet in the rear.

It's just that the attack frequency of the Iron Battlestar is too fast, five minutes is an attack wave, the Earth Fleet can not dodge the first time and the second time, the officers and soldiers of the fleet are extremely nervous, and they try their best to dodge every attack, as a result, in the third round of attacks of the Iron Battlestar, the Earth Fleet still has a battleship that has not been able to completely dodge the attack, and the tail of the battleship was gently rubbed a little by the superluminal space-time wave, and after the violent explosion, the large area of the tail of the battleship was destroyed.

And in the next few rounds of attacks, the Earth Fleet suffered even more damage, and all three warships were completely destroyed, and there was no room for salvation.

At this time, after the continuous artillery fire of the Iron Battlestar, the attack of the Earth Fleet finally landed on the surface of the Iron Battlestar.

Almost at the same time, in a full five hundred different positions, a large number of faster-than-light attacks converged into a furnace, creating an incomparably bright and dazzling dazzling spot in the sky above the Iron Battlestar.

The flesh shield defense layer formed by a large number of sub-light speed spaceships, under the concentrated fire attack of a hundred superluminal attacks at every turn, these spaceships were destroyed in the first time, and the devastating pillars of light penetrated through the layers of spaceships, all the way to the surface of the steel battle star, under the extremely powerful concentrated fire attack, these attacked alloy decks were easily torn through like air, and huge craters hundreds of meters deep were all over the steel battle star at once.

For a while, because of this wave of attacks by the Earth Fleet, a layer of rising metal mist appeared in the sky above the surface of the Steel Battle Star, and countless tiny particles that were decomposed into the basic atomic form were piled up together, forming a thick layer of smoke rising on the surface of the Battle Star, and the others were not directly attacked, but were splashed by the collateral damage, and melted into gas and evaporated to the high surface of the Battle Star under the action of instantaneous high energy, as for the other ships in the outer layer were split into large and small metal fragments by the attached energy shock wave, and for a time they fell into various areas on the surface of the Battle Star。

The collateral effects of the damage to these sub-light ships may seem insignificant, but in fact, if not handled properly, it will cause huge problems to the Iron Battlestar, and if the clouds and debris formed by the material particles are mixed together, if not cleaned up, some of the attack trajectories of the Iron Battlestar will even be exposed.

Fortunately, these small problems were just insignificant small troubles for the Iron Battlestar, and before these small troubles could really play a role, the Iron Battlestar formed a strong magnetic field on the global scale of the Battlestar through some strong magnetic equipment built into the alloy armor layer, and quickly restrained many fluttering material debris to the surface of the Iron Battlestar.

During this period, the Iron Battlestar still kept completing waves of blows to the Earth Fleet, without the slightest sign of relenting.

At this moment, no one knew that Iron Battlestar's heart was crying, this round of attacks it was beaten badly, and a full five faster-than-light cannons were completely destroyed, and Iron Battlestar's heart was trembling. ...
