The scene of tens of thousands of warplanes appearing in the air at the same time is very spectacular, this kind of scene usually only appears in fleet battles in the universe, and it is extremely rare in ordinary intra-atmosphere wars, because the sky in the atmosphere is actually limited, not as boundless as the universe, and there is the influence of gravity, as well as the limitations of the huge plane of the earth, the environment is much more complicated.

Therefore, a large number of fighters appear in a limited space at the same time, which is actually very dangerous and unnecessary, as long as the firepower can reach saturation, more numbers are meaningless.

However, the air battle that broke out today over the junction of the New Apennine Peninsula and the mainland does not apply to such rules.

Those problems that are very headaches for traditional fighters are not a problem for the fierce bird fighters under the control of the absolute domain, and the powerful computing power obtained by Sister Mao through the absolute domain ensures that the fierce bird fighters can maintain extreme flexibility while maintaining a dense formation, and the fierce bird fighters have to face too many enemies.

Countless cannons fired desperately, and the heavily armored cannon bullets crisscrossed the air, weaving a vast web of crossfire, knocking down the flying Blackclaw monsters who dared to invade them in pieces.

Although the shells of the blackclaws could block the fire of small arms, they could not block the large-caliber cannon bullets, but they still fearlessly rushed towards the group of ferocious birds.

Sister Mao is very glad that these monsters have no long-range attack ability, she can't imagine what this air battle will be like if these monsters have long-range attack ability - the flying black-clawed monsters that were shot down in the sky fell to the ground like rain, but the number of flying black-clawed monsters in the sky did not decrease at all, but increased!

The reason for this unscientific situation is that there are more Blackclaw monsters flying from the ground into the sky than the blackclawed monsters that have been downed!

How many flying Blackclaw monsters are there in the sky now?

Lakh?

Or two hundred thousand?

Or, more?

Even if it's learning AI. Sister Mao was also a little unsettled at this time.

Because she found that with only the existing fierce bird fleet, it could not stop the momentum of the enemy's flying troops at all!

And she didn't dare to let the Fierce Bird group be approached by the enemy, the mobility of the Fierce Bird Fighter is good, but the number of enemies is too much, once it is surrounded, no matter how good the mobility is, it will be over!

Grit your teeth. While carefully controlling the group of fierce bird planes to disperse and move around the enemy and open fire, Sister Mao once again controlled 20,000 fierce bird fighters to join the battle, and all 20,000 fierce bird fighters have been reequipped with special air combat equipment.

As a result, following the dense cannons, all kinds of air combat weapons also began to exert their might in the sky, and a large number of air-to-air missiles and even cluster bombs exploded in the sky.

However, it didn't work, and although more flying blackclaws were killed, the monsters continued to move forward slowly but surely.

And because of the containment of these flying blackclawed monsters, the blackclaw monster cluster on the ground is advancing faster and faster!

They're already closing in on the line less than eighteen kilometers long!

A huge roar began to sound, and groups of battleships suspended above the line of defense lined up in firing formations. Start attacking enemies with naval guns that are already within range! ――

Alexander's face turned pale as he looked at the spectacular air battle in the sky not far away, and he couldn't describe his mood at this moment.

The legendary intelligent fleet is as strong as this!

This well-informed veteran of the Imperial Army had no doubts at all about what kind of tragic fate the flying units of the Imperial Army would have against those intelligent fighters who were fighting hard in the sky at this time - not to mention the performance of the fighters themselves, there was no comparison at all, and the superb flying skills and tacit cooperation to the extreme were enough to completely destroy any human pilot!

But it is precisely because of this that Alexander is particularly desperate, because even such a strong fighter force. Tens of thousands of fighters have not been able to stop the forward momentum of those black monsters!

Those black monsters. Actually gave birth to wings, and can fly?

What the hell is this?

Such a biological weapon is too rebellious, right?

Will this line of defense be able to withstand such an enemy attack?

The tall, sturdy line of heavy alloy walls shook as the ground shook as the Blackclaws approached, and Alexander, dressed in power armor, clenched his assault rifle.

"Prepare for battle!"

Although not on the front line, although only in reserve. But Alexander was ready for battle, and he had a hunch that he would soon join the battle!

The blackclaw clusters on the ground finally rushed to the front of the line like a tidal wave.

Countless gunfire rang out, and the various weapons on the battleship cluster in the sky were already firing at full strength, and the battle robots on the defensive line had also joined the battle. The defense line, which was less than eighteen kilometers long, was under full attack, and the number of monsters was simply too many.

Alexander found that the combat coordination of his new comrades could only be described as perfect, he had never seen such an even and efficient firepower net, no waste, no dead ends, and the robots fired with frightening efficiency.

The Blackclawed monsters, who were charging towards the defensive line, fell in large areas like scythe-harvested wheat in a field in front of such a net of fire, and were trampled on the soles of their feet by their companions who continued to rush behind them.

The process was repeated over and over again, and the blackclaws that appeared with a cloud of dust seemed endless, one fell, and the other rushed up, and every step they took was extremely costly, but they didn't care.

In the face of such an enemy, even a veteran like Alexander, who is accustomed to seeing life and death, can't help but feel frightened, but the robots don't have such a problem, they just obey the command of Sister Mao, fire, fire, keep firing.

Eventually, the Blackclaw's advance momentum was stopped by a flattering imperative about three hundred meters from the defensive line, and the scene seemed to be at a stalemate.

However, the ammunition carried by the combat robots is not unlimited, and the non-stop shooting will also cause a heavy burden on the weapon itself and may even cause malfunction, although Sister Mao has long been prepared for this situation, and has prepared a reserve team for rotation to ensure uninterrupted firepower, but the black-clawed monsters are not only a strategy of burying their heads and rushing down.

The alarms of the geo-sounders, which were used as early warning devices, scattered along the defensive line, sounded loudly.

There's something going on underground!
