"Hidden!"

With a loud shout from Tongtian, the colorful pearl in his hand shone brightly, and at the same time, the area locked by the three giant beams, the large array that was originally isolated from the void, actually died down at the same time, losing its previous powerful defensive power, as if it had disappeared out of thin air.

This pearl was left by Fu Xi, not only the center of the Divine Domain Enchantment, but also the control center of this million-kilometer defense line that could not be top-notch formations.

That's right.

It is impossible for Tongtian to let the formation defense line be completely one-sided and passively beaten: at such a distance, the power of the demon's attack is still huge, and the formation is simply not enough to match the attack of the planetary-level railgun, and the biggest way to dodge the attack is to temporarily close the formation.

Woohoo......

As the formation in the locked area suddenly closed, three crimson beams of light tore through the void and swept across the line of defense and disappeared.

The attack, which was originally used to try to destroy the defensive line, suddenly came into the air and did not have any substantive effect.

Obviously, Tongtian is an obvious lure to the enemy to go deeper, just to make the demons tens of thousands of miles apart, and the ultra-long-distance attack will be ineffective.

In this way, it is impossible for the fortress to attack at an ultra-long position of 30,000 kilometers to break the defense line, even if they know that the other side is luring the enemy to go deeper, they have to get closer.

The planetary-level railgun consumes a lot of energy, and seeing that the first blow was avoided by the opponent in this way, the demon side paused for a moment and had to change the way of attacking.

Sou!

Sou!

Sou!

The fortress opened countless portals, large and small, and with a large number of blue light flames that streaked through the void, hundreds of warships of different levels flew out.

The speed of these warships is much faster than that of the huge fortresses, and the smallest warships can reach thirty or forty times the speed of sound, and those large warships are even faster than lightning. They used their speed to the extreme, sweeping towards the side of the defensive line, and given the power and size limitations of the battleship itself, the weapons were not as powerful as planetary-class railguns, so it was impossible to attack from a distance of tens of thousands of kilometers - they had to close the distance to the defensive line.

The planetary-level railgun muzzles on the fortress, with a palpitating glow, hid behind the battleship, on the one hand, to allow the battleship to find its way, and on the other hand, to cover the battleship.

For the demons, the biggest obstacle to entering the solar system is the formation defense line, if you simply use warships to break through the defense line, you will inevitably suffer great losses, those large arrays are not just defense, the attack power they have is extremely terrifying, if you want to break through the defense line, God knows how many warships will be lost?

Therefore, the purpose of the demon race is very obvious.

If the formation continues to close, the ships in front will be able to easily break through the defense line without any losses at all. On the contrary, if the formation is activated again, the planetary-level railgun on the fortress can deal a fatal blow to the defense without waiting for the formation to attack the battleship.

If the formation is not opened, the battleship will pass smoothly.

When the formation is opened, you will face the blow of the fortress.

Between two fires!

The three areas that were previously locked by the railguns, the large array closed to reveal the gap, and it was not opened again to fill it, and hundreds of warships were getting closer and closer to the gap.

Call!

Just as they were about to enter the effective range of the battleship, those battleships released more fighters, and the fighters released more mechs.

Thousands of fighters and tens of thousands of mechs filled the void densely, but they were not chaotic at all, but formed a neat attack formation centered on the battleship.

It's close.

It's closer.

Suddenly!

Just as it was within range of the battleship, not only did the original three gaps not close, but the large array separated by the three gaps also opened.

What's that?

Blocked by the Great Array, there was a steel fortress that was almost exactly the same as the Demon Fortress, incredibly large in size.

At the same time, the distance was shortened to less than a thousand kilometers, and the fortress was filled with a number of weapons that frightened people to death, and they unleashed deadly beams one after another.

Thundered......

The crimson light tore through the void, and those warships, fighters, and mecha under the control of the light brain reacted amazingly fast, and they launched counterattacks one after another.

It's a pity that due to the lack of kinetic energy of its own engine, the attack distance of the mecha is at most one or two hundred kilometers, and the effective attack distance of the fighter is only 1,000 miles, so it can't hit the fortress at all. Even those battleships with extremely strong attack power are indeed very strong in terms of attack strength, but due to the size of the engine, the energy output of an attack is insufficient.

The highest level of science and technology of a civilization is most directly reflected in the energy intensity contained in the attacks that can be launched by combat weapons.

In fact, the attack energy intensity released by the main gun of the four-star battleship of the Alpha Star is exactly the same as the energy intensity released by the planetary orbital run.

Why are railguns so much more powerful?

This is like Qin Yan's multi-directional output of combat skills, the reason why the Earth Demon Technique is powerful is because there are 72 attacks. The reason why the planetary-level railgun is powerful is actually the same reason: the power of the planetary-level railgun is that its energy output per unit time is extremely strong, and the power engine required to support such a huge energy output is also very huge, and the battleship simply cannot load such a large engine, once installed, it will cause a significant drop in flight speed due to volume and weight, and there is no way to even make space jumps.

A powerful attack output is bound to require an extremely huge power engine, and such a huge power engine brings not only powerful attack power but also defense power.

Hundreds of warships fused space technology's main guns to unleash earth-destroying power, and a staggering number of secondary guns tore through the void.

Pity......

Those warships with a length of less than two or three thousand meters have too few weapon systems compared to fortresses with a diameter of more than two thousand kilometers.

The artillery fire that filled the starry sky didn't have time to fall on the fortress at all, and North, who was in the mothership in the distance, had already pointed through the gun barrels of all the battleships through the fortress controlled by the super light brain, and judged the trajectory of all the attacks before launching an attack.

As a result, more and more powerful beams roared out of the fortress, intercepting all attacks in the middle of the road.

After destroying the enemy's attack, the dense rain of light was weakened by less than a percent, and then fell on the energy shield of the hundreds of warships like rain hitting plantains. The next moment, huge fires burst into the void, as bright as red lotuses in full bloom.

In front of this war machine, almost the size of the moon, those battleships are as vulnerable as papier-mâché lanterns!

Burst! Burst! Burst!

The Demon Fortress, which was more than 10,000 kilometers away, did not stop for a moment and was in full fire, but when the attack of the Demon Fortress spanned more than 10,000 kilometers, the interval was enough time for the fortress controlled by North to launch a second attack. It's just that North didn't intercept the opponent's attack, but staggered the attacks of both sides, and each hit the opponent's fortress itself.

All kinds of light cannons filled the void, and the deafening sound of the cannon fired without low-tech artillery, but when the attack hit, it shook the sky.

"Damn! How could these natives have sixth-level civilization technology? The commander of the demon fleet in the fortress roared sharply at the top of his throat.

"Commander, it's not good, the energy shield is badly damaged!"

"The indigenous fortress clearly intends to die with us, and all of them will be attacked by staggered attacks, and they will only attack wildly against the fortress itself!"

"Energy Shield Defense reduced to 60%!"

"Energy Shield Defense Reduced to 55%!"

"Evacuate the fortress!"

The Demon Commander finally made a decision, because he knew very well that the two fortresses had equal firepower, and the fortresses were too large and too flexible, once the other party made up their minds to die together, it would be impossible for the fortresses on their side to evacuate. If you use warships to fight against the opponent's fortress and try to give your fortress a chance to retreat, you will inevitably lose a large number of warships: if you send fewer warships, it will be impossible to hold back the opponent, and if you send too many warships, you will only suffer heavy losses.

Next, Tongtian, who was staying in the control room of the mothership, saw a terrifying scene.

I saw more than 10,000 warships, flying out of the demon fortress!

More than 10,000 warships, what does this mean?

Except for some transport ships, which are relatively weak in firepower, the other warships are all two-star warships at worst: the Golden Dragon has fought against a two-star battleship, and with the talent of the Golden Dragon, the combat effectiveness is definitely the best in the same level, and even then it is slightly weaker than the two-star battleship.

In other words, the firepower of a two-star battleship is almost equivalent to that of a moderately talented, mid-to-late stage martial artist of the Tianwu Quadruple Heaven.

Of course, Jin Long was in a special situation with that two-star battleship, because he had to fully resist the battleship's artillery fire, otherwise the battleship would attack Qin Yan and the others. However, in actual combat, the warrior will use the flexibility of the battleship to dodge to a certain extent.

Although it is said that the light-speed strike cannot be dodged, it is only after the relative attack is launched, and in fact, the battleship needs to mobilize its guns to lock on to the target, which has a very small time difference.

But even in the actual confrontation, the warrior has the advantage of flexibility, that is limited, isn't it?

How many Heavenly Martial Four Heavenly Masters are there on the human warrior's side?

The original number of people in Zhongzhou Shenling, plus the temporary increase of the Divine Blood Pool, plus the Phoenix brought over, was only more than a thousand people.

At this level alone, there is a gap of seven or eight times!

Thundered......

The two huge fortresses bombarded each other, their flight speed was much slower than that of the battleship, and coupled with the huge body, there was no way to avoid the opponent's light-speed attack.

It was as if two medium planets were suspended in the air, and between the two fortresses, a huge number of beams of light converged into a river, connecting them together.

Eventually, with a loud bang that almost shattered the heavens and the earth, the two huge fortresses burst into the air and perished like a planet explosion.

Having lost the fortress of war, the Demon Clan's plan to destroy the human defense line at no cost has come to naught.

More than 10,000 warships, ranging from two-star to four-star, with different firepower and size, formed a huge triangular attack formation and drove towards the defensive line.

Having lost the protection of the fortress, the higher-ups on the demon side also knew very well that this would be a life-and-death war, and they would have to break through the human defense line no matter what: in the past, they could withdraw to the fortress without breaking the defense line, but now they have lost the guarantee of retreat......
