The huge surface of the Iron Battlestar is empty everywhere, and there are only all kinds of high-end weapons and equipment that operate fully automatically and freely on the endless alloy metal continent, and all kinds of free-moving defense robots exist, which seems to be empty everywhere, but in fact, every corner of the surface of the Battlestar is filled with all kinds of security access control and monitoring facilities.

Although it may seem absolutely sparsely populated on the surface, it is definitely not an easy task to successfully infiltrate the interior of Iron Battlestar.

The Iron War Star is a huge alloy metal planet, which is not at all small compared to ordinary planets, and on the surface of the planet, it is said that there should be some small life forms such as plants and insects.

But in fact, the entire surface of the battle star is well maintained at all times, even if the steel battle star has been asleep for millions of years, there are various monitoring facilities monitoring the situation on the surface of the battle star at any time, and there are countless automatic robots that are dispatched at any time to clean up any miniature creatures that are more than one millimeter and have more than a hundred groups on the surface of the planet.

Therefore, it can be said that there are real living beings on this steel battle star, and even flies and mosquitoes don't want to survive on the surface of this planet, let alone enter the battle star through various access channels with strict access to breed and breed and do evil.

Even the various materials that are attracted by gravity and make a forced landing on the surface of the battle star from the universe are monitored by the battle star monitoring system at any time and place, and after accumulating to a certain scale, they will be disposed of on a regular basis.

At this time, although there are a large number of Earth fighters acting and destroying on the surface of the battle star, which has restrained a lot of attention from the Iron Battle Star, it is still an extremely difficult thing to successfully infiltrate the inside of the battle star.

Although the various weapon systems of the battle star are trying their best to attack the earth fighters, according to the consistent war operation procedures of the steel battle star, including the logic of robot behavior, etc., the entry and exit control measures inside and outside the battle star at this moment are much stricter at this moment.

Even the seemingly hectic and complex order of robot action is actually extremely strict rules.

Although from time to time there will be some automatic opening channels in and out of many automatic robots, but there are many safety guards in each channel, including robots during the passage period, every object in and out must undergo strict inspection, what X-ray detection, sonar detection, passage permission serial number, entry and exit weight monitoring, etc., all kinds of unbelievable strict control procedures, so that the air can not circulate freely inside the battle star.

It can be said that in the seemingly busy passages, the behavior of all robots is controllable, and there is a strict order, each robot does not enter and exit through the same channel, and the opening and closing of internal levels also have a completely independent control system.

Any material, personnel, or even information flow that attempts to infiltrate the Iron Battlestar through these portals will be isolated into different levels, making it easy to infiltrate the deep layers of the Battlestar.

The deep world inside the huge Iron Battlestar is like an incomparably huge labyrinth, not only is there surveillance everywhere, there are traps and death zones everywhere, but the real passage to the deep inner area will only open at a specific time, and it is precisely because of such strict internal management measures that the Iron Battlestar will never be in danger of falling in the war with various civilizations and all kinds of lives for millions of years.

The Iron Battlestar's access control is so strict that even for the powerhouses of the Immortal Realm of the Earth civilization, they are almost helpless.

In the huge structure of the entire battle star, in addition to those self-opening passages, even the thickness of the armor in the weakest area is often hundreds of meters thick, and such a thick alloy armor is not simply composed of only one or two alloys, it is doped inside and outside, embedded with multiple layers of alloy materials, and even has a special layer of lead alloy inside, which has a strong anti-penetration and anti-interference ability.

Even if the powerhouse of the Immortal Realm has an extremely powerful ability to penetrate the material barrier and has various magical Five Elements Escape Methods, it is extremely difficult to easily cross the outer barrier composed of this layer of composite materials.

And even after passing through these barriers and entering the interior of the battle star, although behind the armor layer are closed cabins, which seem to be easier to pass through, but these cabins are so many that they can be superimposed to a depth of tens of kilometers, and the layers are obstacles, and the adjacent cabins are often made of different materials, and there are also layers of electricity between the cabins, and there are various different detection devices all over the place, even if something can penetrate through these cabins, it will take an incomparably long time to penetrate layer by layer, and consume immeasurable energy。

Even this infiltration itself will create a variety of different anomalous data in the various routine monitoring data of the layers of cabins, and through the monitoring of these data, which are often unchanged for a long time, Iron Battlestar can also receive early warnings, so as to avoid the continuous deterioration of the situation as much as possible.

In short, although this ancient cosmic civilization itself has not encountered the opponent of the cultivation civilization, at the beginning of its initial design and construction of the Iron Battle Star, it also spent a huge price to purchase the basic blueprints, various design principles, and design concepts of the Battle Star weapon from other more ancient and advanced cosmic-level civilizations.

Therefore, the steel battle star that was finally formed under its careful construction has a strong ability to defend itself by nature, even if it is a variety of spiritual civilizations and cultivation civilizations that scientific and technological civilizations are not good at dealing with, this kind of steel battle star also has extremely powerful defense, anti-infiltration, anti-interference, and anti-hijacking capabilities.

Even the robot civilization, the information virus civilization, etc., which are the most restrained to the scientific and technological civilization, are difficult to easily have a restraint effect on the Iron Battlestar.

Although the powerhouses of the Immortal Realm of the Earth Civilization can already be called profound cultivation and strong strength, and they can often cause a big scene of planetary extinction on ordinary planets by relying on their own strength, but it is also difficult to sneak in easily on the Iron Battle Star.

At the very least, these Immortal Realm powerhouses are often unable to face when they are faced with the many security monitoring mechanisms within the Iron Battlestar, and the extremely dangerous and complicated choice of access roads.

After all, the powerhouses of the Immortal Realm are only the most powerful and lethal when they are faced with various lives, they are often easily able to interpret all kinds of life information, and can gain insight into various loopholes in life, and they are extremely powerful at the spiritual level.

But in the face of the internal operation mechanism of the Steel Battle Star, which has been unmanned for millions of years and has been operating mechanically and intelligently, the strength of these Immortal Realm powerhouses will undoubtedly be greatly discounted.

Fortunately, the earth civilization has naturally considered this situation for a long time, and when these immortal realm powerhouses were arranged to carry out the infiltration plan, the earth civilization had already prepared the corresponding response plan.

Before leading the team to lead all the infiltrators to a robot passage, a powerhouse of the Immortal Realm with an extremely high level of cultivation had already taken out a small and delicate bronze mirror from the storage ring.

This bronze mirror seems to be unsightly, but it is a powerful magic weapon refined by Sima Mulong, and it even seals a wisp of Sima Mulong's own divine will.

It can be said that this bronze mirror itself was carefully prepared by Sima Mulong for these immortal realm powerhouses to complete this infiltration plan.

It has no superfluous functions, and its only ability is to penetrate the good and evil, and point out the source of danger, so as to provide convenient guidance for the powerhouses of the Immortal Realm in the process of infiltrating the inner passage of the Iron Battlestar.

No matter how complex the internal defense and monitoring mechanisms within the Iron Battlestar are, the security settings within an area at the same time and place also have their limits, and they often only take into account one aspect.

In some places, attention is paid to detecting whether there is any abnormality in the material structure of the traffic target, some areas pay attention to monitoring whether the weight value of the traffic target changes in the process of passing, and some areas are to check whether there is a problem with the traffic target through the interpretation of energy radiation.

In this process, if there is no corresponding reasonable response to the target, it is often easy to take care of one or the other, and after a few rounds of detection, it will be unconsciously exposed, and finally it will be pulled out early by the Iron Battlestar.

However, after the infiltration team of the earth civilization has this bronze mirror, it is equivalent to mastering the customs clearance code, and can adapt to various situations calmly.

No matter how it is said that it is also a powerhouse of the fairy realm, these infiltrators of the earth civilization also have a variety of cultivation methods, when facing gravity detection, these practitioners can directly offset the quality of the items they carry, and when facing X-ray detection, they can carry out invisible processing of the carrying items, all kinds of means are enough to ensure that there are no mistakes even if they deal with the various monitoring methods of the steel battle star.

But even so, this infiltration process can be called difficult, the inside of the Iron Battlestar is simply ten steps, one card, five steps and one sentry, there are few places to rest safely, here is simply a corner of the wall with a black light, the pipes are full of various induction components, everywhere is full of malice, and even the slightest change in smell will cause suspicion and alarm.

It is also thanks to the fact that the infiltrators of the earth civilization are all the soul clones of the strong people in the fairy realm, they are not material existences, they are not dragged by the physical body, they do not need to take care of food and excretion and other troubles, and their own abilities are strong enough, so that they can successfully survive in this seemingly calm and terrifying environment full of deadly killings, and they can dive deeper and deeper.

However, even these immortal realm powerhouses of the earth civilization are struggling to move within the Iron Battlestar, and the monitoring devices in many areas are very troublesome and energy-consuming to deal with, so that the progress of the infiltrators seems to be very slow.

And the passage inside the Iron Battlestar is not just a matter of entering if you want to, the passage here is usually automatically closed anytime and anywhere, and only when the materials and equipment are passed, some passages will be temporarily opened, and often the opening time is only a few tens of seconds, and the opportunity is fleeting.

The infiltrators of Earth's civilization often have to wait for a long time in some passages before they can enter the deeper areas.

Fortunately, the Iron Battlestar is too huge after all, with a radius of thousands of kilometers, and the internal space is almost immeasurable, and it is undoubtedly impossible to maintain such a tight arrangement everywhere in such a huge internal space.

Therefore, after going two hundred kilometers deep into the interior of the battle star and passing the last extremely strict checkpoint, the infiltrators of the Earth civilization finally entered a relatively lax area.

This is the factory area inside the steel battle star, the extremely complex and busy production tasks are carried out here all the time, a large number of materials are constantly being transported back and forth, the equipment is running non-stop, all kinds of noise, exhaust gas, waste liquid, waste residue and other unpredictable situations emerge one after another, maintenance robots are constantly running back and forth between various production line workshops, and it is undoubtedly very unrealistic to establish a set of meticulous monitoring mechanisms in this production area.

Therefore, it is inevitable that there are a large number of monitoring holes here, and even Iron Battlestar does not have the ability to monitor this place without blind spots.

So the infiltrators of the earth's civilization stopped here.

Thanks to the bronze mirror provided by Sima Mulong, the infiltrators of the Earth civilization had a smooth journey, without leaking any horses' feet or causing any noise, and without the Iron Battlestar noticing, they had quietly infiltrated the inner depths of the Iron Battlestar, gathering in this area where the monitoring force was weak.

This is already deeply into the inner area of the Iron Battlestar, even the Iron Battlestar itself is difficult to have a huge courage, and it is easy to give up such a large part of the area, so the personnel of the earth civilization have infiltrated this level, and it can really be said that the fishing has stabilized the fish, so that the big fish of the Iron Battlestar is completely impossible to get out of the hook easily.

At this time, even if the infiltration of the Earth civilization is exposed, there is no need to worry about what the Iron Battlestar will do.

So the infiltrators began the second step of action.

After evading the near-omnipresent surveillance power of the Iron Battlestar and arriving at a huge ore storage chamber that was safe and empty, these Immortal Realm powerhouses took out pieces of teleportation array arrangement components of different sizes from the storage rings.

After a period of assembly, smelting, and repair, they finally succeeded in assembling a small teleportation array, and then the teleportation array was activated, and one after another, fully armed fairy realm powerhouses began to walk out of the teleportation array.
