Everything evolves.

Sometimes evolution, sometimes degradation, when the environment changes, organisms change themselves in order to adapt to the environment.

It's the same with weapons.

Whenever a breakthrough is made in technology and a change occurs in the state of warfare, a large number of new types of weapons emerge from the hasty invention of patting the head to the natural development of long-term technological accumulation. Its evolution is complex, the variety is huge, and the speed is rapid, comparable to the process of biological evolution.

But there is a decisive source of difference, or evolution, in the evolution of weapons and living things.

Whether it is evolution or evolution, the ultimate goal of living things is to continue the population for the sake of the old energy, in other words, to make changes for survival. Weapons, on the other hand, are aimed at killing other lives, and are the product of malicious intent, without any concept or idea of perpetuating the population, and all actions are only carried out around the destruction of the enemy. Therefore, weapons with autonomous mobility do not fear death or pain, they only blindly advance, destroy, ravage, and annihilate.

From the air, the mold-like black mass was gradually spreading on the ground, and the battle that had been mixed with blood and fire was replaced by a uniform pitch black.

The march of the "Legion" was extremely rigorous.

The so-called rigor does not mean that its queue is neat, as meticulous as a military parade queue. Rather, it refers to the fact that it always adjusts the allocation of troops in response to the battle situation, and at the same time keeps the momentum and rhythm of the march in order. You must know that under normal circumstances, this is something that only veterans and elite masters can do for many years, and ♀ some inorganic lifeforms that have only been a little more oblique since their birth have mastered this skill, and they use it as naturally as breathing.

That alone is enough to make people's hairs stand on end.

It's not incomprehensible to respond to the situation, and regardless of the level, everyone has some adaptability, even if the brain is not good, imitating other people's responses can cope with it all of a sudden. Humans can't achieve this skill, but those black crystal aliens use this skill so easily, and they use it as a matter of course, and in the eyes of humans, it's like a super dream.

Not to mention, the multiplication of this skill by the ever-increasing base is even more chilling.

At the head of the queue are always drones of various models. They are responsible for seizing air supremacy, long-range attack and observation, combat relaxation, reconnaissance, electronic warfare, ground attack, and targeted killing, and are the vanguard of the "corps." Whenever their black and oppressive figures appear in the sky, the large army of the "legion" will not be far away. If a swarm of drones appears, and anyone who is not stupid and wants to alarm the rear, then he must immediately start a race against time, because if he can't complete this task in 30 seconds, then he will most likely never have a chance to complete his mission again. After the drones take turns licking the ground and attacking, there will basically be no living people in the trenches, and the communication facilities will inevitably be completely destroyed.

Of course, things aren't always so absolute. According to the experience of modern warfare, in Afghanistan and Vietnam, even after poison gas, flooding, gas explosions, and fuel-air bombs, there are always survivors in the tunnel fortifications who survive, and many of them are still fighting hard. When the survivors of the raid crawled out of the underground fortifications and onto the ground, which was littered with rubble and charred corpses, they still had no chance to warn the rear. First, all communication lines have been completely destroyed, and the air is full of interfering radio waves blocked in all bands; second, the huge multi-legged foot troops of the main force of the "legion" are about to come up.

Speculation is that multi-legged mobile devices are not popular with technology researchers.

Although it is much better than the wheeled or crawler structure in terms of adaptability and stability in complex terrain, it is only the gap between the nine scum and the five scum. What's more, in order to improve terrain adaptability and reduce grounding pressure, the more walking feet, the better on soft ground, such as mud and swamps, multi-legged walking devices are easier to sink into than crawlers, and if you don't want to fall into it, you will become a centipede), and the more walking feet, the more complex the structure will be, and the more difficult it is to write the control program. However, when carrying out the charge of armored groups in open areas such as the Great Plains, the performance of multi-legged centrifuges is not better than that of tracked and wheeled armored vehicles, and the economic cost and operating cost are still thrown off a lot. In the end, I can only go to the mountains and street fighting environment to exert my residual heat.

Despite these shortcomings, the main ground force of the "Legion" has evolved into a multi-legged walk, and the reason is that they are not machines, but inorganic life forms, and their special ecological structure determines that they are only suitable for this complex and inefficient way of action in the eyes of others.

The blood of silicon-based organisms is liquid oxygen.

They breathe air like carbon-based organisms and sustain life by ingesting oxygen and substances. Unlike carbon-based organisms, they do not need and will never consume carbohydrates, which is extremely toxic to silicon-based organisms.

When the micro-effect body that makes up the intermolecular force of the base cluster of silicon-based life comes into contact with the carbon molecule, it will go out of control, causing the microscopic level to collapse, and when this collapse spreads to the memory media, even the basic form cannot be maintained, and the regeneration and repair function is completely suspended.

The carbon molecule is the source of organic life, the ubiquitous substance that pervades the whole world.

In order to survive in this highly toxic environment, inorganic life forms have evolved a unique life cycle system. They first store liquid nitrogen in the body, then cover it with thermal insulation, which separates the liquid oxygen from the atmosphere and stores it in the body like blood for circulation. During this compression cooling process, oxygen and nitrogen are the first to evaporate, and finally the insoluble carbon dioxide is expelled in the form of dry ice.

In order to store liquid nitrogen and liquid oxygen in the body, and effectively use oxygen and nitrogen, inorganic life forms generally use exoskeleton structure, which does not rely on muscles but generates power through high-pressure oxygen during exercise, similar to hydraulic transmission). In addition, the liquid oxygen generated can also be used as an oxidizer to produce high temperatures that can dissolve not only organic matter, but also inorganic matter.

When hundreds or thousands of walking inorganic life weapons launched a group charge, there were no individuals or organizations that could withstand this storm.

It was supposed to be like this.

However, 15 minutes have passed since the battle, whether it is the melee type of high-frequency blades, electric whips, rockets, the high-speed tungsten core barrage poured by the reconnaissance type Gatling machine gun, the twin-mounted 88mm railgun of the light combat model, the three-pack 125mm coil cannon of the heavy combat model, the light-type laser cannon, and the heavy-light charged particle cannon have failed to take Roland's life.
