Planet Fortress, as the name suggests, uses planets as fortresses. However, even a real planet has a limited thickness of its shell.

Take the earth as an example. The structure of the entire earth is divided into crust, mantle and core. The crust is equivalent to the main armor belt of the earth, and the mantle is a circle of flowing semi-solid lava, responsible for supporting and buffering. As for the core, it is the energy core of the entire earth.

For the earth, the hard external crust is his main means to resist external attacks, but this layer of armor belt is less than 30 kilometers. Even on some extremely deep seabeds, the thickness of the crust is only more than ten kilometers.

But even so, even the asteroid collision that destroyed the dinosaurs did not penetrate this thin layer of earth's crust.

The current Mars Fortress has alloy armor belts up to 1,000 kilometers thick. Although these armor belts are not solid, they are composed of layered complex structures, which are somewhat similar to the composite armor of human tanks. However, its defense effect is far better than the crust formed by a mere rock layer.

Yun Qi felt relieved when he thought that his Mars Fortress had an alloy layer of nearly 1,000 kilometers. However, what he was curious about was how Iona did it? After all, after the Emperor of the Universe changed to a planet, the thickness of the armor layer was only a few hundred kilometers.

However, the Universe Emperor has an incredibly huge fire energy that can strengthen his armor layer, making it reach hundreds or even thousands of times the defense effect of ordinary alloy armor.

Looking at Yun Qi looking at him in confusion, Iona tilted her head and thought for a while and said, "Iona did nothing. When she used nanodeformed particles to transform, the entire Mars became a physical metal planet. Iona just hollowed out the middle structure and transformed it into the power core and installed some driving devices at the same time. As for the external armor belt, it was originally the metalized crust and mantle layer left during the transformation!"

After hearing Iona's explanation, Yun Qi suddenly understood.

Iona did not build such a thick armor layer by herself, but Mars, which was converted into metal, naturally has such an all-metal armor layer.

Iona just cut corners and didn't want to spend time to transform the appearance of Mars.

This natural armor defense is much better than what position shield.

Just like the composite armor that humans first studied, it said that at the same thickness, its defense is several times that of homogeneous armor. However, the artificial fortifications with the most powerful defense never rely on any composite armor to protect it.

The most reliable way to defend is to cover the top of your head with hundreds of meters of steel and cement. Keep any nuclear bomb or ground bomb you have to stop!

Armor defense, thickness is the king!

Artillery attack, caliber is justice!

Now that the Mars Fortress has a thick enough armored defense belt, Yun Qi doesn't believe in the weak universe emperor!

Yun Qi completely gave up his position and directly pressed the Mars Fortress on the face of the Emperor of the Universe, and slapped him!

You fuck me, I fuck you!

This is how both sides confronted me!

Rumble!

The angry cosmic emperor roared out an artificial sun that could melt everything, and smashed it hard on the surface of the Mars Fortress!

And this time, the furious Emperor of the Universe lost one of the zodiac palaces at a time.

A series of twelve artificial suns sounded on the surface of Mars at the same time, almost equivalent to millions of nuclear bombs igniting on the surface of Mars at the same time!

If this were the original earth, it would probably have been blown to pieces.

But when this violent flash passed, there were only twelve super-huge craters with a depth of 200 kilometers and a diameter of more than 3,000 kilometers appeared on the surface of Mars!

"The armor belt is damaged by 20%! The fortress has no abnormal operation!" Yu Qidu reported it mechanically. The Mars Fortress and the Universe Emperor had been fighting each other for a long time, and the appearance of both sides almost burst into a pockmarked face!

However, such a serious injury still did not hurt the muscles and bones. Yun Qi truly understood this time. Planet Fortress is not something that can be destroyed by external forces. No wonder every time I watch a science fiction movie, I can only destroy it by myself.

When Yun Qi heard the assessment of the loss tube of the forehead, he was very rude. He said casually: "Turn the Mars Fortress and continue to face him! Then an electromagnetic cannon array occurred, adding a little acne to the face of the Emperor of the Universe!"

Hearing Yun Qi's order, the fire control commander Angela said impatiently: "It's useless to fight. Yun Qi, do you have any powerful weapons! For example, star destroyer, star destroyer, star destroyer!"

Looking at Angela who was deeply resentful, Yun Qi shook his head and said, "With that thing, I will fight against the Emperor of the Universe like this. Okay, girl, be good! Keep beating him!"

"Hmph!" Angela, who was very upset by Yun Qi's perfunctory attitude, pressed the launch button hard, and then a large number of electromagnetic orbital guns grew from the ground on a huge open space on the surface of Mars instantly.

These large-caliber artillery cannons with large caliber that can be stuffed into trucks can flatten a small island with one shot. Hundreds of thousands of such giant cannons fired at the same time, and the scene was simply spectacular.

Boom boom boom boom!

After spanning 300,000 kilometers, hundreds of thousands of super-giant electromagnetic shells hit the face of the Emperor of the Universe, causing a huge flame explosion!

In an instant, this fierce electromagnetic cannon attack created at least hundreds of huge meteorite craters with a depth of more than three kilometers on the face of the Emperor of the Universe.

"You angered me! Ant!" It was obvious that the penetration power of this wave of electromagnetic cannon attack was strong enough. Although it still could not penetrate the energy armor belt of the universe emperor that was as thick as 300 kilometers, it at least had hurt him!

"I want to completely devour you!" The Emperor of the Universe, who was already tired of shooting like this, finally used his trick to devour the stars!

I saw a huge sinkhole appeared on the front of this fortress planet transformed by the Universe Emperor. This huge depression with a diameter of more than 3,000 kilometers was the mouth of the Universe Emperor.

He used this ability to devour the planets to destroy countless planets with intelligent life, completely crushing those planets and converting them into energy.

Buzz ~

A huge space vibration came violently. When the Emperor of the Universe used his planetary devouring ability, a gravitational wave appeared out of thin air. The huge Mars began to be affected by this gravity and headed towards the Emperor of the Universe!

"Captain, I detected a gravitational well with unknown principles. The Mars Fortress is being dragged towards the Emperor of the Universe!" Iona immediately reported after discovering that the Mars Fortress had moved.

"Let him suck! No, we have to speed up and hit it in one go!"

"But Iona, you're sure how long the Mars Fortress can last. If your calculations are wrong, we'll be completely done!" Yun Qi asked.

"The probability of error is less than 30%. My calculation information comes from the historical data recorded by the Transformers clan on the universe emperor!" Iona replied.

"Thirty percent, that is, if you are not lucky, you will be completely destroyed!"

"Okay! Take a gamble! Order the Alliance fleet to retreat immediately and prepare for external fire support. Are the Autobots and Decepticon troops ready?"

Hearing Yun Qi's inquiry, Yu Qi, who was in charge of the communication, immediately replied: "Yun Qi, the raid troops are ready!"

Seeing that everything was ready, Yun Qi suddenly stood up and ordered loudly: "Winning and defeat are here, I will order the raid plan to start immediately!"

With Yun Qi's order issued, the Mars Fortress accelerated suddenly and rushed into the mouth of the Emperor of the Universe in the direction of the gravitational well!
Chapter completed!
