More than 1,000 kilometers away, on the four huge aerospace aircraft carriers, two young men, Shen Minghai and Huang Xiaoxia, were calmly directing the attack.

Although there is no war situation in front of us, the high-altitude reconnaissance plane is constantly gathering news to the aerospace aircraft carrier.

Shen Minghai stopped the calculation in his hand and said quietly: "It is estimated that with two more attacks, the Heavenly Machine Pavilion will be completely sunk." ”

Next to him, Li Wei looked at the complicated calculation formula written by Shen Minghai, and was a little puzzled: "It's good to attack with a direct bomb, why do you need to calculate?"

Shen Minghai looked at Li Wei, and a joke flashed in his eyes: "Senior, if your question is known by Mr. Zhang, it will probably make you return to the Beidou Academy to listen and study." ”

Li Wei's face suddenly darkened, and he bared his teeth and said, "Little guy, be careful that your words cause public anger!"

In other words, although Li Wei and others benefited a lot from auditing the course, the matter itself always made the masters a little stupid - our group of old guys who are dozens or even hundreds of years old actually learn from these teenagers, which is really a bit embarrassing. Especially in the previous exams, I didn't even fail!

Huang Xiaoxia, who was next to her, touched Shen Minghai's shoulder, turned her head and said to Li Wei: "Senior, when we visited King Jing's Mansion before, we found that the defensive enchantments of these large cities are very similar to the high-level enchantments in the spaceship of Liuli Island.

According to the current translations, this kind of high-level enchantment, which seems to be called 'grain boundary', is a more advanced enchantment that already has a little bit of four-dimensional properties.

However, the defensive enchantment of the Jingwang Mansion is only an incomplete grain boundary, and there are many shortcomings.

But no matter how many shortcomings there are, grain boundaries are grain boundaries, and ordinary physical attacks, etc., cannot destroy their defenses. Unless there is a master who does not destroy the golden body, or does not break the peak of the golden body, without any constraints, he attacks with all his strength in a point-to-point manner, and there is hope to break the defense.

And that kind of extreme attack, we can't do it for the time being.

Even if the fighter is allowed to collide, its attack power per unit area may not be comparable to the single-point attack of the top master. ”

Li Wei listened and nodded slowly. He still understands this, and he has also learned these basic knowledge in his previous audits and studies. After thinking about it, Li Wei asked, "If according to what you said, just ordinary attacks and explosions can't break the defense at all?"

Shen Minghai nodded: "Yes." Ordinary means of attack will not be able to break through the defense at all! What's more, the defense of the Sky City will inevitably surpass the defense of the land city and the defense of the Jingwang Mansion.

And on the master side, we don't have it either. You can't pull King Jing Sun Jing or Hades King Yin Boyang to attack. Wouldn't that tell people that we can't!"

Li Wei's eyes were a little worried: "We lack that top master, and the bomb attack power is not enough, so ...... How do you achieve your strategic goals?"

Shen Minghai picked up his draft, waved it a few times, and said with a smile: "But we have knowledge! This is the foundation of the Dayang Group." ”

After a pause, Shen Minghai began to explain: "This is the principle of explosion damage that we have recently studied.

The power of gunpowder can open the mountain.

But according to the rules of conservation of energy, the power of gunpowder itself is not enough to smash the mountain. So what is the reason why the power of gunpowder exceeds the rule of conservation of energy?"

Without waiting for Li Wei to speak, Shen Minghai continued: "This is the principle of explosion. It's actually quite simple, there are tiny cracks inside any substance. To put it simply, it's like the ice crack of crystal and jade. But these cracks are smaller, at the molecular level, even at the atomic level.

Also, matter itself is not absolutely homogeneous. Even the finest single crystal spirit material we have refined has impurities inside. Because of different cooling, different heating, and even the influence of gravity, different moisture content, etc., it will lead to slight differences within the substance.

But it is these small differences, small cracks, that lead to different transmission of the shock wave of the explosion. When the shock wave is strong enough, the matter will crack along these tiny imperfections.

That's how explosions work.

And the transmission of the explosion is powerful, that is, the shock wave. In simple terms, it can be understood as sound waves. Sound waves, with energy!"

"I understand!" Li Wei suddenly realized, "The sound wave carries energy, but the enchantment can't block the sound wave!" Therefore, the fundamental core of this attack is not an explosion, but a shock wave!"

All the planning is carried out around the shock wave.

In the past, some attack methods such as fighting cattle across the mountains actually inadvertently discovered the application of shock waves, right?"

"Not bad. Shen Minghai was a little proud, and shook the draft in his hand again, "This is the core of this battle." With a piece of paper, I can pry a city in the sky!"

"Amazing!" Li Wei couldn't help but extend his thumb. The longer I stay at Neptune, the more I understand the power of knowledge.

Because of knowledge, they can break through the Fa Phase!

Because of knowledge, there is now Dayang Group!

Also because of knowledge, Dayang Group is opening up a brilliant future!

Shen Minghai didn't speak again, because the fighter had already begun to return.

The aircraft carrier immediately became busy, the fighter plane stayed for less than a minute, and all the missiles were reloaded, and then the fighter rushed out of the aerospace aircraft carrier, flew above the aura layer, and regrouped at an altitude of 300 kilometers to prepare for the second charge.

............

But when it came to Tianji Pavilion, everyone was still in a daze. This unprecedented way of warfare has left everyone at a loss.

The total attack time before and after is less than 20 seconds, and strictly calculated, it is only about 16~17 seconds. However, in this short period of more than ten seconds, Tianji City suffered a heavy blow!

The explosion is over, but the phenomenon caused by the explosion is not.

The shock wave on the ground had evolved into a violent wind, which swept up the sand, gravel, loess, and stumps and leaves that spread wildly, leaving a mess everywhere it passed.

In the sky, many of those who were close or poorly cultivated were dizzy and swollen from the violent explosion, and some people even had blood oozing from the corners of their ears, noses and eyes.

But the most eye-catching thing is, of course, the Sky City of Tianji Pavilion!

In the explosion, cracks appeared and shattered on the rock base under the Tianji Pavilion (Sky City), and pieces of rubble and dirt dust rolled down.

The entire Heavenly Machine City trembled in the explosion.

At this point, the aftermath of the explosion had just begun, and a cloudy, scattered mushroom cloud was tumbling in the sky. Gravel and dust were scattered beneath the city in the sky.

Because the gravel and dust went from the inside out, the defensive grain boundary did not stop it.

From a distance, the Sky City of Tianji Pavilion at this time was miserable. Flames tumbled above, and a tail spilled from gravel below.

The entire interior of the Heavenly Machine Pavilion was even more chaotic.

The pavilion master of the Tianji Pavilion, Lu Xianxian, was at a loss at this time - the defensive enchantment was intact, but why did the Tianji Pavilion suffer a heavy blow?

There is a large population in the Tianji Pavilion, and there are more than 500,000 people in a sky city within a radius of ten kilometers, most of which are cultivated under the Yuan Ying (Yuan Dan)!

At this time, there are many people who have suffered serious internal injuries because of the shock wave problem. Some have died.

And the pedestal of Tianji Pavilion is also an alarm. In the energy core in the center of the Heavenly Machine Pavilion, the device that had been operating for more than 100,000 years without problems, at this moment, a large number of red and yellow lights were flashing, and sharp alarms were constantly superimposed in the small space.

A landscape of imminent destruction.

A large number of masters of the Tianji Pavilion rushed out and explored high in the sky. But by this time the fighter had long since disappeared.

Seem...... Let's go?

Lu Xianfeng gradually came back to his senses, and while directing the disaster relief, he sent people to search the surroundings. Then he entangled the thirteen lords and the rest of the masters in the later stage, preparing to go to the west to uproot the Jingwang Mansion and find and annihilate the people of the world.

As for the surrounding 'audience', they are also in a daze at this time. Some people feel uncomfortable, but others feel shocked. Especially when I saw the Sky City of Tianji Pavilion, it seemed that there was a tendency to disintegrate, and I was even more vigilant.

For example, Biyuntian's Zu Qianyue and others looked vigilant. Old Ancestor said with emotion: "A few more times such an attack, this Tianji Pavilion ...... I wonder if it will disintegrate?"

Everything is in a panic. It's three minutes – three minutes actually doesn't do anything.

Then, Zu Qianyue's eyes suddenly flashed, and he saw the 'black dot' again. This time, black dots came from all directions, about hundreds, flying from east, west, north, south, and five directions above.

In the Tianji Pavilion, Lu Xianxian's eyes instantly turned red: "Stop! Stop these things!"

These things can't be allowed to explode anymore, the Tianji Pavilion has been seriously damaged - due to time constraints, it has not been overhauled at this time, but the Tianji Pavilion has already begun to prepare for landing.

Dozens of masters swarmed out and pounced on the black dots in the distance. But...... When these masters approached, they cut off these 'missiles', but suddenly found that they were empty shells!

Not good!

Rushing to the forefront, Bai Zhu, the owner of Tianmen Tower, changed his complexion greatly. Suddenly turned his head, but saw 100 meteors falling from the sky again.

This time, the 'Meteor' no longer flew above the Heavenly Machine Pavilion, but split into two columns and passed from the north and south sides of the Heavenly Machine Pavilion.

The 'meteor' flashed by, and ordinary masters didn't have time to intercept it. However, Lu Xianfeng of Tianji Pavilion made a move angrily, and a few sword lights flashed, and he actually cut down four fighters.

But the fighter pilot activated the 'escape charm' almost at the same time. In addition to one fighter pilot who was split on the spot, the remaining three appeared directly thousands of miles away, on the air-space carrier!

The escape charm is also a one-way random teleportation charm that needs to be located in advance. Although the Ocean Group has not researched the teleportation array over the years, the research on the teleportation charm has been very good!

And in front, here in the Tianji Pavilion. The remaining 96 fighters roared away. Behind these fighters, there are a full 400 bombs!

Or 20 cloudburst bombs, and 380 oversized bombs.

The same explosion happened again. This attack, after Shen Minghai's calculations, explosions appeared from both ends, and a strong shock wave formed a hedging relationship within the Sky City.

Only a dozen seconds after the explosion, suddenly a clicking sound came into Lu Xianxian's body - this sound came from under his feet!

Lu Xianxian's face suddenly stiffened!

In the eyes of the 'audience' outside, they saw that in the explosion, there was no longer just rubble under the Sky City, but also rocks dozens of meters in size had begun to crack!

Cracks like lightning, spreading on the surface of the hideous pedestal.

A clicking sound came into the keen ears of many masters.

I don't know how many people's pupils have constricted.

Could it be that the city in the sky has existed for more than 100,000 years...... To be destroyed?

As for Lu Xianxian, the pavilion master of Tianji Pavilion, he reacted quickly, his eyes were red, and while letting people accelerate the landing of Sky City, he pointed at Bai Zhu, the second master of Tianji Pavilion, "Go to the sky to intercept." When the Sky City lands, we'll have to find these bastards!

Seconds passed, and the city in the sky began to land. But the landing of such a huge city in the sky obviously cannot be as swift as a fighter jet. In fact, the castle in the sky is very bulky, and its landing speed is about 5~6 meters per second.

At an altitude of ten kilometers, it takes almost half an hour to descend to the ground. And when approaching the ground, you must also slow down carefully.

One minute...... Two minutes...... Five minutes passed in the blink of an eye, and the fighter did not reappear.

The city in the sky is getting closer and closer to the ground. Gradually, the distance was less than two kilometers. Lu Xianfeng relaxed a little.

But Lu Xianfeng didn't know that at an altitude of 500 kilometers away and 500 kilometers, a white-painted reconnaissance fighter was circling. Under the cover of the clouds in the sky, the people on the ground failed to spot the reconnaissance plane.

On the plane, Shen Minghai used the latest large-aperture telescope of the Dayang Group to see the situation of the Tianji Pavilion 700 kilometers away in a straight line. Even the height can be accurate to the level of 10 meters.

There are also 96 fighter jets, hovering thousands of miles away, ready to dive and accelerate.

Shen Minghai observed while writing and drawing on the draft. When Sky City was about 1.8 kilometers above the ground, a trace of seriousness flashed in Shen Minghai's eyes:

"Attack! as planned!"

The 96 fighters in the sky accelerated violently, and when the fighters arrived in front of the Tianji Pavilion, the Tianji Pavilion was already about a kilometer above the ground.

The Sky City has a range of ten kilometers, and at this time, it is less than a kilometer above the ground, so the space between the Sky City and the ground is about half a sealed space.

And at this moment, the fighters dived again, this time each fighter carried six missiles, fully loaded!

In addition to the decoy missiles, a full 480 missiles successfully reached the bottom of the Sky City.

And then...... The heavens and the earth trembled! The flames rushed up dozens of kilometers into the air.

It was a picture that countless people will remember for a lifetime.

Zu Qianyue, who was watching from the sidelines, saw it clearly:

The crazy flames exploded, and a flood of flames gushed out from below the Sky City, and the Sky City that was landing was forced to rise hundreds of meters, and the ground was undulating like a quilt, and then the center of the Sky City was uplifted, and flames rushed out from below, like a volcanic eruption.

Then the Sky City of the Heavenly Machine Pavilion shattered, and endless fragments were scattered over a range of dozens of kilometers, and even more flames rolled into the endless sky.

At sunset, the earth is burning!
