For those small calculations made by the US government, Liu Ruian can guess without even investigating.

But what about that, Liu Rui'an is not rich and capricious now.

Before switching to such a world, and still a big world with many dimensions and dimensions, Liu Ruian will definitely cherish and develop well.

But now, it's just a "farm farm" used to promote a certain research result, or a few research results.

No, just when the US government was shocked by the power called "Budo", and even a mortal could have extraordinary power, a bigger disaster came.

A spaceship apparently from an alien civilization, well, to be precise, a reduced version of the dead star appeared in the star system where the earth is located.

Immediately afterwards, there was a wave of small spaceships with three digits in number, rushing towards the earth from this seemingly problematic alien spaceship.

Looking at the obvious weapon systems on these alien spacecraft through the satellite system, as well as the fierce battle formation, no one thinks that this is a friendly place to visit except those with mental illness.

Therefore, while the internal problem of the mutated pharmacy is getting bigger and bigger, the entire earth civilization has to face the invasion from the extraterrestrial civilization.

After these three-digit alien spaceships easily broke into the earth's atmosphere, the following battle process made countries all over the world feel relieved and at the same time full of a sense of crisis.

The reason for the sigh of relief is simple. Although alien spaceships have shown strong technological power in battle, they are not indestructible.

Even if you explode an alien spaceship, the Earth may have to pay a dozen or even dozens of fighters, but it is better than not being able to fight.

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

No pilots of any kind were found in the alien spacecraft that was shot down.

This means that these alien spaceships belong to the category of "drones" to some extent.

Then the question is coming.

This time, a three-digit UAV can be dispatched, so what will be the next time?

For human civilization, the number of fighters produced is never a problem.

The problem is that the man flying the fighter!

It is impossible for talents in this field to fall directly from the sky, and it takes a long time to train and train.

In this case, let alone a ten-to-one battle loss ratio, it is one-to-one, and the earth cannot hold it!

The loss of 100,000 fighter jets cannot be borne by the nations of the earth.

But the loss of 100,000 drivers, huh ... No country can afford it.

Fortunately, these batches of alien drones were shot down. Although most of them were directly detonated, a small part of them still fell to the ground.

With the wreckage of these alien drones, governments of all countries are confident to reversely analyze related alien technology within a certain period of time.

But it didn't happen that it appeared in spherical alien spaceships that depended on the asteroid belt, and did not give humans much time.

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

What is desperate is that this time the UAV formation is still in the three-digit range, but it has soared from more than 300 before to 800.

Through observations by deep space probes, all countries have come to the answer that an alien is "farming" using the rich materials of the asteroid belt.

Facts have proved that this conclusion is not wrong, because when the third wave of alien UAV formations were discovered, the number had successfully exceeded the three-digit mark.

This is not counted. The most desperate thing is that in addition to the previous UAV formations, new models have appeared in the alien spacecraft formation with up to 3,000 aircraft this time.

After these spacecraft, which are significantly larger than the previous two drones, landed on the ground, the countries that only had to deal with enemies in the air discovered the presence of an alien army.

Not surprisingly, the alien army is not a flesh and blood creature, but a robot.

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

There are animal-like shapes, human-like shapes, and heavy-duty vehicles.

Unlike the various alien robots that have been suspended in games and American dramas, these things gave countries a slap in the face as soon as they appeared.

Extraordinary speed, extraordinary defense, extraordinary power, plus a variety of energy weapons.

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

In the wording of the network, the troops of various countries were directly shot by the alien robot army.

Even the proud long-range strike has completely lost its effect.

When the satellites in Earth's orbit were exploded one by one, the countries on the earth soon found themselves in danger of becoming "blind".

However, things did not end there!

After the satellites of human beings were continuously exploded, alien satellites soon appeared in the earth's orbit.

The biggest difference between these satellites and human satellites is that each of them has its own means of attack.

From high-powered energy weapons to throwing "iron rods" directly, the threat to the earth can be absolutely devastating.

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

But from the moment the battle started, the unknown alien obviously didn't want to destroy the entire earth.

Otherwise, it would be necessary to send ground troops and directly use the increasing number of satellites in Earth orbit to conduct orbital strikes.

In the situation where all human satellites are exploded ~ lightnovelpub.net ~ Even if it is not completely "blind", it is basically impossible to prevent orbital attacks by aliens.

However, when the situation of the entire human civilization is getting worse and worse, the mutants have played a role enough to surprise the entire human society!

Not to mention the extraordinary effect of the mutant ’s extraordinary nerve response ability on air combat.

Merely face-to-face with the alien army on the hard anus, the mutants can exert enough power to shame ordinary humans to death.

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

However, what really shocked the whole world was that Abelil O’Neal and Leonardo, who held the status of Xuanwumen disciples, wiped out the aliens one by one without any harm. Human tactical squad.

Looking at the entire human civilization, we will face the tragic fate of being annihilated or enslaved. No matter the mutant or the martial arts practice method of the Xuanwumen, it will soon become a "life-saving straw" in the hands of countries. (To be continued.)
