On the capital star of the Kabate Empire, thick smoke is rising everywhere on the surface at the moment.
First, it was hit by fragments of the fortress, and before it could catch its breath, it was bombarded again from orbit by the warships of the Human Federation.
Nowadays, all activated anti-air defense systems have been destroyed at targeted locations, and only some well-hidden and unactivated defense systems are still alive.
After a wave of attacks by battleships, millions of high-speed falling fireballs appeared in the sky. They were the first wave of airborne mechas from the Human Federation, totaling 5 million units.
Their mission is to search for and clear out missed anti-aircraft firepower and provide support for subsequent airborne troops!
Nowadays, there are no small defense systems left in the Kabat Empire. All large ones, whether activated or not, were completely destroyed when the first wave of battleships attacked.
These small defense systems do not pose a great threat to the mecha. After all, the mecha's maneuverability is too high. Even if it is unfortunately hit, as long as it is not the cockpit, the pilot's life can be saved by ejection.
But the assault ship is different. If it is hit, it will basically result in the destruction of the ship and the loss of lives, and at least hundreds of people will be killed in one battle.
Therefore, assault ships dare not directly carry out airborne landings without support.
Fifteen minutes later, the ground mecha troops sent out a signal and had cleared all the defense systems they could find.
After receiving the news, the second batch of airborne troops began to break into the planet's atmosphere. This batch of troops included 60,000 assault ships and 13 million mechas.
In the middle of the assault ship, 13 million mechas surrounded it, forming an airtight protection network!
Sure enough, there were still hidden fish that slipped through the net. Several ordinary-looking storefronts suddenly opened up, revealing the internal anti-aircraft defense system, and the attack began!
If there were mechas nearby, they would immediately react and destroy them. If there were no mechas, a warship within the shooting angle would directly fire a secondary cannon into the soul.
These anti-air defense weapons can basically only fire once before being quickly destroyed after being exposed. However, a fire is also a fire. There are still several mechas that use themselves to intercept the firepower of the assault ship in order to protect it.
Fortunately, none of the dozens of mechas that were hit had any critical injuries, and three of them were seriously damaged and the pilots were ejected, so no one was killed.
As the second batch of airborne troops landed on the ground, the purge began!
Now the soldiers of the First Legion no longer need Lin Fan to reiterate orders. Everyone knows what they should do without any hesitation!
The commando team cooperated with the mechas and quickly occupied the Kabat Palace, but Fahal was not found. Finally, after a careful search, they finally discovered the secret passage leading underground.
However, its downward path has been completely blocked, and the commandos and mechas are helpless for a while.
But when the news reached Lin Fan's ears...
"Have all troops within a 300-kilometer radius of the Kabate Palace evacuate quickly, and then directly use a Mark III earth-penetrating nuclear bomb!"
"Yes, legion commander!"
The Mark III earth-penetrating nuclear bomb is the most powerful earth-penetrating bomb currently developed by the Human Federation. It can drill to a maximum depth of 1,000 meters. It is called the nemesis of underground fortresses!
800 meters underground of the Imperial Palace, the command post of the Kabat Royal Fortress.
"Your Majesty, the humans who invaded the Imperial Palace have begun to retreat!"
"Huh? They had clearly discovered the entrance to the bunker just now. Why did they retreat? What did they want to do?"
Although the bunker is very strong, Fahar also understands that humans can always break through as long as they take some time. It is just a matter of how long it takes.
Therefore, when human beings discovered the entrance just now, they knew that they were doomed and there was no hope of salvation.
But now the humans started to retreat. This operation made him very incomprehensible. However, the next moment, the humans told him with actual actions why they retreated!
On the Ouranos, a missile launch port was opened. A minute later, a huge missile with a long tail flame was shot from the Ouranos. After adjusting its attitude, it headed towards
Plunged into the planet.
When the missile passed through the atmosphere, the shell suddenly ejected in all directions, revealing its true appearance.
Once people take a look at it, they will understand what this missile is used for!
This is not the old-style ground-penetrating bomb in the conventional sense. The old-style ground-penetrating bomb relies entirely on the strong body of the projectile to hit it hard to achieve the effect of penetrating into the ground. However, this method can only penetrate the ground for about 200 meters at most.
That's the limit.
The Mark III earth-penetrating nuclear bomb is a completely different thing. In addition to its stronger body, it also comes with a powerful drill bit. This drill bit is made of the hardest material that humans can currently create.
When the projectile hits the ground, the drill bit will start, and the propeller on the projectile will also start, and it will continue to drill all the way. This powerful drill bit can support drilling down to a depth of at least one thousand meters!
Fahar in the bunker also saw the picture of the bullet slamming into the ground and beginning to drill downwards.
How could he not guess what this thing was? His face turned pale.
"Your Majesty, human weapons are constantly drilling down. They have already drilled to a depth of 300 meters. No, it is already 400 meters now, and it is still going on!"
In the command room, the chief of guards anxiously said to Fahal.
Everyone was anxious, but no one had any way to stop this. They could only watch as the things marked on the screen got closer and closer to the bunker.
"Your Majesty, human weapons are less than 30 meters away from us!"
The chief of guards turned around and shouted to Fahal, but what he saw was Emperor Fahal who was completely sluggish, without any movement at all!
Finally, this Mark III ground-penetrating bomb completed its mission and drilled directly into the shell of the fortress. After all, the shell was still very hard, and the drill bit had been severely worn by now. It was definitely impossible to drill through the shell.
However, there is no need for it to penetrate the outer shell and reach here, and his mission has been accomplished.
Inside the fortress, Fahal even heard the sound made by the ground-penetrating bomb that just hit the outer shell of the fortress.
The next second, Fakhar didn't even have time to think about it, because the Mark III earth-penetrating nuclear bomb had detonated, directly destroying the underground fortress.
If you look from the sky, you can even see that a large area of the ground has been lifted up. The original imperial palace suddenly became ruins, and even caused a moderate earthquake. The power is evident.
In the orbit of the planet, Lin Fan witnessed this scene from the bridge of the Ouranos.
Speaking of which, this is already the second emperor that Lin Fan has killed!
