Liu Rui'an can guess the little abacuses made by the US government without having to investigate.

But so what? Liu Rui'an is no longer rich and willful now.

If it were the past, such a world, and it had many dimensions and dimensions, Liu Rui'an would definitely cherish and develop well.

But now, it is just a "breeding farm" used to promote one or several research results in your hands.

Just when the US government was shocked that a mortal, called "martial arts", could actually have extraordinary power, a greater disaster came.

A spacecraft that obviously comes from an alien civilization, well, to be precise, should be a reduced version of the death star appear in the star system where the earth is located.

Then came a wave of small spacecraft with three-digit numbers, rushing towards the earth from this alien spacecraft that seemed to have some problems.

Through the satellite system, looking at the obvious weapon systems on these alien spacecraft and the fierce battle formations, no one would think that this was a friendly visiting place.

Therefore, while the internal problems of variant agents are becoming increasingly greater, the entire earth civilization has to face invasion from extraterrestrial civilizations.

After these triple-digit alien spacecraft easily entered the Earth's atmosphere, the subsequent battle process made countries around the world feel relieved and full of crisis.

The reason why I breathed a sigh of relief was very simple. Although the alien spacecraft showed powerful technological power in the battle, it was not indestructible.

Even if an alien spacecraft is blown up, the Earth may have to pay more than a dozen or even dozens of fighter jets, but it is better than not being able to even fight.

As for the sense of crisis, the reason is also very simple.

No pilots of any form were found in the downed alien spacecraft.

This means that these alien spacecraft belong to the category of "drone" to some extent.

Then the question is.

This time, three-digit drones can be sent, so how much will it be next time?

For human civilization, the number of fighter jets produced has never been a problem.

The problem is the person who flies the fighter!

It is impossible for talents in this field to fall directly from the sky, and they all need to go through long-term training and training.

In this case, not to mention the battle loss ratio of more than ten to one, even if it is one to one, the earth cannot hold on!

The losses of 100,000 fighter jets are not unbearable for the United States on Earth to unite.

But the losses of 100,000 drivers, haha... no country can afford it.

Fortunately, after these alien drones were shot down, although most of them were directly blown up, a small number of them still fell to the ground.

With the wreckage of these alien drones, governments of various countries are confident that they will reversely analyze relevant alien technology within a certain period of time.

But it is true that it appears in spherical alien spacecraft relying on the asteroid belt, which does not give humans much time.

After the first wave of invasion ended, only half a month later, the second batch of alien drone formations appeared again.

What makes people despair is that although the drone formation this time is still in the three-digit range, it has soared from more than 300 aircraft to as many as 800 aircraft.

Through the observation of deep space probes, all countries have come up with the answer that an alien is using the rich materials from the asteroid belt to "farm".

It turns out that this conclusion is indeed correct, because when the third wave of alien drone formation was discovered, the number had successfully exceeded the triple-digit mark.

This is not counting. The most despairing thing is that in addition to the previous drone formation, new models have appeared in the alien spacecraft formation with a number of up to 3,000 this time.

After these spacecraft that were obviously much larger than the previous two drones landed onto the ground, countries that had only had to deal with the enemy in the air discovered that alien army had appeared.

Not beyond the expectations of the staff groups of various countries, the alien army is also not flesh and blood creatures, but robots.

This type of robot is divided into several types. The shortest one is about two meters high, and the highest one is more than five meters.

There are forms similar to certain animals, forms similar to humans, and even more similar to heavy vehicles.

Unlike the various alien robots that were beaten in games and American dramas, these things slapped countries hard as soon as they appeared.

Extraordinary speed, extraordinary defense, extraordinary power, and various energy weapons.

As soon as the army of various countries contacted the alien forces, the entire battlefield showed a one-sided situation.

If it is changed to the Internet, the troops of various countries are directly shot out by the alien robot army.

Even the proud long-range strikes have completely lost their effect.

When the satellites in the earth's orbit were blown up one by one, the countries on the earth soon discovered that they were in danger of becoming "blind".

However, things didn't end there!

After humans' own satellites were constantly being exploded, alien satellites soon appeared in the orbit of the earth.

The biggest difference between these satellites and human satellites is that they all have their own means of attack.

From high-power energy weapons to directly throwing "iron rods", the threats that can pose to the earth are absolutely devastating.

Fortunately, it is fortunate that although the origin of the aliens is still a mystery, the attitude is also very unfriendly.

But from the moment the battle began, the alien of unknown origin obviously did not want to destroy the entire earth.

Otherwise, there is no need to send ground troops and directly use the increasing satellites in the earth's orbit to conduct orbital strikes.

With the situation where all human satellites were blown up, even if they were not completely "blind", it would be basically impossible to guard against alien orbital strikes.

However, just as the situation of the entire human civilization became increasingly unfavorable, mutants played a role that was enough to surprise the entire human society!

Not to mention the extraordinary neural response ability of mutants, how effective it will be in air combat.

Just facing the alien army, the power that mutants can exert is enough to make ordinary humans ashamed to death.

Especially after countries used the wreckage of alien troops to create armor, energy weapons and other equipment, the mutants actually achieved amazing results on the ground battlefield.

However, it really shocked the whole world that Aiberiel O'Neal and Leonardo, who were in charge of the identity of Xuanwu Sect disciples, wiped out one tactical team after another without any injury.

As the entire human civilization is about to face the tragic fate of being exterminated or enslaved, whether it is a mutant or the martial arts practice method of Xuanwu Sect, it soon became a "life-saving straw" in the hands of various countries. (To be continued.)
