The heads of state appeared on the big screen one after another, and everyone's faces were grim.

Because this is the first time that the earth has connected to the interstellar interface, no one can say what the final result will be.

In the past three years, although all countries have been trying their best to develop day and night.

But their potential enemies are unknown aliens.

No one knows to what extent their science and technology have developed, and the panic in the hearts of the heads of state can be imagined about such an enemy who has no understanding.

When the unknown energy arrives at Jupiter, it has already entered the monitoring range of the Sky Brain satellite.

Under the instruction of the supreme commander of Great Xia, Zhang Keqi quickly made public the monitoring images of the Tiannao satellite.

It is also in this monitoring screen that everyone finally saw the true face of Lushan, which has been laid out for three years.

The composition of the unknown energy is composed of four elliptical aircraft, the front one is smaller than the three behind, and there is no intuitive weapon configuration.

The three planes behind seemed to be guarding the small flying machine, and they kept pushing through space at the same distance and at the same speed.

"It's really aliens, they still came ...... eventually"

"This is a team of alien vehicles, and it looks like the target is really Earth, but what exactly is their purpose?"

"What's next? Can our latest weapons really compete with extraterrestrial civilizations? ”

Finally seeing the face of this unknown energy clearly, Zhang Keqi frowned solemnly.

With the benefit of the supreme command, Zhang Keqi has become the main person in charge of the Earth Space Defense Program.

Judging from the current situation, it will only take a few days at most for these aircraft to reach the sky above the earth, so soon Zhang Keqi issued orders to various countries in the world on behalf of Great Xia:

"All countries quickly entered a state of combat readiness, and all three major Earth-Moon space platforms entered the first level of alert.

Ladies and gentlemen, the unknown battle has arrived, and now it has reached the point where we need to share the enemy's hatred.

Three-year layout, just for this moment......"

Zhang Keqi's voice sounded in the command rooms of various countries, and there was almost no hesitation, and all countries quickly began to respond.

Several Western powers, led by Atlantis, have erected cosmic-grade air defense weapons in more than eight military bases.

This is the second line of defense after the three platforms, and it was specially developed to prevent aircraft from entering the earth and causing damage to the ground.

In the three-year layout, various countries have formed a group and formed three lines of defense under the leadership of Great Xia.

The first is the three Earth-Moon space platforms, including Nantianmen, and the second is the cosmic-level air defense weapons in the eight military bases.

Despite the fact that there are only 8 military bases, this cosmic-level anti-aircraft weapon is enough to form an intertwined network in the Earth's stratosphere.

And the third line of defense, which is also the last line of defense of mankind, is the armored soldiers.

This is the worst-case plan, if the first two lines of defense fail to prevent the aircraft from descending on Earth, the rest of the matter will have to be armored soldiers to defend the peace of the Earth one after another.

For the next two days, it was as if the countries were living like a year.

The heads of state stared at the dynamics of the four alien vehicles in front of the display screen inch by inch.

On the Luanniao platform, the wolf warrior has been urgently transferred back and once again assumed the role of defense commander-in-chief.

Only this time, you can still see the faces of some foreigners on the Luanniao platform, who are also wearing armor and integrated into the defense team.

In the face of a common enemy, no one in any country can hide their selfish intentions, after all, if even the earth cannot be saved, then national sovereignty is even more of a joke.

What's more, in the past three years, everyone's intentions have been obvious to all countries.

They have provided technology and manpower to help countries develop, and in just three years, the technological level of countries has made a qualitative leap.

The unreserved nature of Great Xia has also made many countries sincerely obedient and established an inseparable cooperative relationship with everyone.

Therefore, at this moment, in the defense force on this Luanniao platform, there are many elite soldiers sent by countries.

Just as there will be soldiers from the Great Xia Kingdom stationed on the other two platforms, it is no longer the time to divide the country, but the first head-to-head confrontation between Earth and other galactic civilizations.

Finally, in the early morning of two days later, with the rapid sound of sirens and the brief flashing of red sirens from the command room of the joint attack of various countries, the time to come finally came.

Four spacecraft appeared directly in front of the Luanniao platform, and at this moment they had reached the sky above the earth.

What made everyone pay more attention was that these four flying machines suddenly hovered in the air, a technology that is still beyond the mastery of the earth.

The smaller one was quickly lifted up, protected in the middle by the other three aircraft, and the four aircraft just stopped there calmly, facing the Luanniao platform without any movement.

Watching this scene through the big screen, Zhang Keqi quickly gave an order to the technicians around him:

"Mobilize the Sky Brain Satellite to Detect the ...... of these four spacecraft"

The technicians quickly began to control the Sky Brain Satellite, and at the same time, on the Luanniao platform, a mecha team composed of more than 30 Menshen series mechas, came to the platform with heavy steps, looking up at the four spacecraft directly in front of them.

The Xuanwu fighters and Luanniao fighters have been in place, the ion cannon has begun to charge, and the electromagnetic energy wave has also entered the stage of imminent launch.

The Menshen series mecha is equipped with a unique kernel drive system, which gives full play to the advantages of space warfare.

Although the Door God series mechs are huge, the smallest Gate God series detection mecha is also more than two meters tall, while those battle mechs are as tall as four or five meters.

This mecha would be very clumsy and slow to move in the earth's environment, but the unique core drive system and operation method in space can still achieve the effect of this mecha to achieve flexible effects.

In the distance, the Earth-Moon Space Platform of the Atlantan Empire, and the Earth-Moon Space Platform of the Ice Bear Country, echoed the Nantianmen of Great Xia.

As the three parties on the platform jointly pressed the start button, the electromagnetic energy wave was quickly emitted from the three platforms, and the three platforms were soon established, and the interrelated electromagnetic barriers of the three platforms were soon established.

This is in case the aircraft suddenly launches an offensive against the platform, and it is difficult to break through the electromagnetic barrier with long-range artillery fire within the calculation range of the Sky Brain satellite.

But this is only a theory after all, because no one knows exactly what kind of weapons this aircraft is equipped with.

Therefore, until now, the leaders of various countries did not dare to take it lightly, and just stared solemnly at the four flying machines that appeared on the screen.

For some reason, the four flying machines suddenly stopped moving, and just stopped there quietly, which made the leaders of the countries of the earth a little confused for a while.

Zhang Keqi, who was standing in the command room, crossed his arms, frowned and looked at the picture of the return, thinking in his heart what these four aircraft were trying to do when they came all the way here?

"Didi...... Didi ......"

However, at this moment, there was a sudden shrill alarm sound in the space station, and then the technicians hurriedly operated in front of the computer, and then looked back at Zhang Keqi and said quickly:

"Commander-in-chief, the Sky Brain satellite has detected an unknown energy that is projecting the Earth.

It is suspected to be a probe wave from a spacecraft, which is probing the Earth. ”

"Dog's Day ......"

Zhang Keqi gritted his teeth angrily:

"I was almost deceived by appearances, this aircraft is not in a stalemate with our three major platforms, but has already begun to scan the earth in secret.

Fortunately, in the past three years, we have also upgraded the space guide satellite, otherwise I am afraid that it would not have been discovered.

Immediately activate the electromagnetic shielding, notify all countries, and immediately intercept the detection wave of the alien aircraft! ”

Zhang Keqi's order soon spread to various countries, and eight major military bases with high-tech weapons and equipment were set up, and they quickly began to respond.

The signal towers that went straight into the sky were soon activated under the central control of computer satellites.

An invisible barrier, quickly connected to each other, formed in the air.

Zhang Keqi looked at the screen simulation barrier in front of him, which had already formed a protective shield above the earth.

And the embodied probe energy wave is indeed bounced off the protective cover.

This scene made Zhang Keqi smile knowingly, and the defensive means set up at the beginning finally played a role.

The energy waves of the alien craft cannot pass through this protective shield.

Until now, however, no one knew why these ships were here to explore Earth.

But at least they know that they don't let the other party know their own details until they know each other's details, which is the most important thing.

"Buzz ......"

It seems that the energy wave has been discovered, and the earth can no longer be detected, and the energy wave continuously released by the alien vehicle on the big screen has disappeared.

Zhang Keqi solemnly looked at the dense data map on the screen, and was even more anxiously guessing what these aircraft would do next?

However, at this moment, the energy wave that had disappeared just now actually reappeared, only this time this energy wave quickly passed through the barrier above the earth.

"What's going on? Why is the barrier not working? ”

In the face of Zhang Keqi's questioning technicians, he quickly began to investigate, and only after a while did he stand up and say:

"Commander-in-chief, the alien vehicle has increased the power of the detection wave, and we can't parse this energy."

"What?"

Zhang Keqi actually thought for a long time that this situation might happen, after all, the degree of development of alien civilizations must not be what the earth can imagine.

But even the maximum power detection wave of the alien spacecraft, the barrier of the earth cannot resist.

Doesn't this mean that in front of alien aircraft, the Earth is as if it were completely transparent?

The anxious Zhang Keqi quickly ordered the technicians to launch a counterattack, but no matter how much the Sky Brain satellite increased the power of the barrier, it could not effectively resist the detection wave.

Other countries soon detected that alien vehicles were exploring the Earth, and for a while, there was no way to shield the detection waves.

These 4 alien vehicles are obviously a very complete exploration team.

The smallest kind of extraterrestrial vehicle should belong to the probe vehicle, and the probe wave is released by this vehicle

The other three aircraft are equipped with some armed equipment, but their main role is still mainly for detection.

It's just that they don't seem to be able to release a powerful detection wave like this small flying machine, but what is the specific detection method? We don't know yet.

At a time when everyone was struggling with the status quo, what didn't anyone expect was ......

"Buzz ......"

The small vehicle that had been releasing detection waves to explore the Earth had self-destructed without warning.

In a vacuum, the small aircraft suddenly exploded, and although there was no sound, a layer of powerful energy spread out.

The closest to the aircraft was the wolf warrior on the Luanniao platform, and the others were all puzzled when they looked at the small flying machine that suddenly exploded at the moment.

So far, the Earth side has not launched any attacks, so why did this aircraft blow itself up?

This scene also confused scientists from various countries, and Zhang Keqi quickly ordered technicians to find out the reason for the aircraft's self-disclosure.

Technicians calculated from many angles, but found no results, until they traced the monitoring route of the energy wave after entering the Earth, and found the clue.

"Report, this aircraft was detected at this location at the last moment before the explosion, and the energy of the detection wave was exactly ......"

While talking, the technician enlarged the map, and after seeing the clear picture, Zhang Keqi's eyes flashed a little shock.

"Shengu Mountain?"

From the backtracking detection footage, it can be clearly seen that the energy detection wave released by the spacecraft stayed in Shengu Mountain for at least a minute.

This situation had not appeared before, and all the probes were often a passing feeling, only when the energy wave of Shengu Mountain stopped, as if some problem had been detected.

Looking at the screen in front of him, Zhang Keqi was silent for a moment before he sorted out an idea in his mind:

"In other words, the reason why this spacecraft self-destructed was because it detected Shengu Mountain?"

The technician quickly brought up another image, which was a satellite scan of the energy threshold of the Divine Lonely Mountain Generation:

"Commander-in-chief, there has indeed been a very complex energy in the area of Shengu Mountain, which can be detected by satellites, but it cannot be scanned."

"It's Dao Ancestor, it must be him!"

Zhang Keqi's eyes lit up, and he said thoughtfully:

"Since Dao Ancestor retreated in Shengu Mountain, this complex energy has only appeared, so it must be related to Dao Ancestor.

I think it should be that this spacecraft can't parse such complex energy, which is why it will cause the center to be damaged and thus self-destruct.

This is unbelievable, the power unleashed by Dao Ancestor is so unbelievable that even alien civilizations can't snoop on? ”

However, just as Zhang Keqi's words fell, the flying machine, which had been standing motionless in the air, suddenly burst out at an extremely high speed and approached the earth.

"Oh no, after the long-range probe didn't work, they decided to rush right into Earth to scan?"

"Attention, get ready to fight!"
