Although the underground tunnel dug by Oro and other ground-digging insects caused two breakthroughs, the rushing insects could not escape the interference of the defenders and could not attack the human defense line from behind.

However, at this time, the firepower of the long-range artillery weakened and could no longer suppress the Qilazeng army on the front. The two sides had entered a fierce battle stage of close combat.

This is thanks to the aerial assault of the Qilazeng people.

The small world has limited space and cannot deploy a fighter fleet, so the Longxiang Army can only give up air supremacy. Faced with the dense swarm of insects, the ground air defense firepower can only be passively defended.

Shartula had seen before that melee whirlwinds can cause large-scale damage and are almost invincible. This time she was not alone in the army, but she was covered by a large number of friendly forces. After entering the artillery position, she immediately flapped her wings and rotated. Within dozens of meters, both machinery and creatures were shattered to pieces.

When he was fighting the feathers, Shartula was the first to rush into the feathers army formation and used a whirlwind to break the formation, thus helping the Qila Empire defeat the main force of the feathers.

Princess Hahoran looks like a wasp, of course, much bigger than a hornet and is about the same size as a fighter. She is good at long-range poisoning, and her group poisonous arrows spray like rain, and when they touch objects, it will corrode. The poisonous smoke rising will also cause secondary damage.

Hunter Ayamis can attack from close combat and long distances, and will also strengthen nearby friendly forces.

There are two main air force of Qila Zola. One is the Shartula, who has hands, feet and wings, has strong combat power and high intelligence. Some can cast spells, while others are melee combat; the other is the Zola Zola, which is similar to the wasp, which has long-range poison spray, long-range nail sting, melee biting, and melee attacks and long-range attacks.

Another advantage of the insect troops is that they are numerous, and tens of thousands of elite insects are just a part of them. The most disgusting thing is the uncountable number of small insects, like black clouds covering the sky.

Why can locusts cause disasters? A single locust is very weak and will die with one foot. However, when the number exceeds the critical value, any life that stands in front of the locust swarm will be gnawed away.

The small insects in the Qila Empire are more ferocious than locusts, and even steel and concrete are still gnawed. Their number also exceeds the critical value, and the key is that they are still under the command and organized.

There are so many insects that are rushing up to bite without fear. Who is not afraid?

The long-range strike force has been retracted into the fortifications, and a large number of air defense fire points have been destroyed. Only the air defense cannons in the core area of ​​the fortress are protected by energy shields and can continue to be output.

Thousands of ultra-high-speed anti-aircraft guns were shot to the point where the barrel became hot and shot down thousands of bugs, but it was just a drop in the bucket for rework in the sky.

On the main protective shield, insects were densely covered with insects, and they were biting the shield with sharp mouthparts. From a distance, it seemed that the color of the shield changed from light blue to gray-black.

The shield energy is decreasing rapidly every moment. The staff in the energy center constantly replaces the evacuated energy crystals, but still cannot prevent the energy level from decreasing.

"Po", the energy shield finally couldn't stand the cracking. Countless insects buzzed and flew down, and their sharp mouthparts shone with cold light. Even the strong special reinforced concrete fortress vowed to chew it out.

Billions of insects covered the fortress building areas like dust, and the rustling sound of eating made the scalp numb.

Seeing that all humans were indented into fortifications as turtles, Princess Hahoran, who was in charge of commanding the air force, looked back and was thinking about whether she would return to the frontier battlefield to reinforce.

At this moment, a tremor that made people feel bored and vomited came, and even Hahoran was affected, as if the organs in his body were hit hard, so he could not fly steadily.

Not to mention the little bugs, they did not appear to be scarred on the surface, but the internal organs in their bodies were completely broken. Tens of thousands of insect corpses fell down like rain.

Before Hahoran could figure out what was going on, a shock wave came, and more bugs broke their internal organs and fell down after they died or were seriously injured.

This time, she sensed that the shock wave was coming from several special windows in the human fortress, and the closer it was to the fortress, the greater the trauma it caused.

Humans must have hidden some secret weapons in the fortress, but now there is no way to break through the fortress to use this weapon, because almost all the insects within 500 meters of the fortress were dead.

Within 500 to 15000 meters, powerful insects can still withstand the weak insects. If they fall a little further, they will only be affected and not fatal.

If you have a little scientific knowledge, you will know that this is a disease infrasonic weapon.

Taichu Chaos Laboratory obtained samples of Qila Zombie people very early. After repeated experiments, it was confirmed that the best way to kill these insects on a large scale is infrasound. As long as the frequency is adjusted, it can only target the insects, and the harm to the human being is minimal.

This is the advantage of human beings. It is not about fighting against insects, but about using wisdom to develop targeted tactics and weapons.

However, due to current technical limitations, the scope of infrasonic weapons is limited and requires a huge energy supply, so they can only be directly supplied by the fortress energy core.

Originally, Chu Xiongtian planned to tug at the outer defense line for a while, and then withdraw the main defense line of the fortress to use the ultimate move. Unexpectedly, the Qilazeng people had too much appetite and dared to cross the outer defense line to siege the core position as soon as they came up. So naturally they had to give them some ruthlessness.

After using the infrasound weapon once, the Qilazeng man was prepared and it was impossible for him to achieve such brilliant results.

At the same time, many gates in human fortifications opened, and thousands of troops rushed out. Air defense weapons also extended out from the shooting ports, poking out flame tongues to harvest those insects who were affected by infrasound waves and could not fly steadily.

Several holes were also opened at the top of the fortress, and a large group of drones flocked out. These drones are about one meter in wings, with two pairs of dragonfly-like wings. The body structure is very small, but they are holding a missile that is larger than the fuselage.

If it weren't for the magic and various black technologies nowadays, such an aircraft mechanism would not be able to fly at all. Its ability to fly completely depends on the wind-type rune magic array on the fuselage, and the function of the wings is only the direction of mediation.

Even so, the drone holding a missile is not fast. It will only be shot out when it searches for the target and activates the missile thruster. At this time, the missile provides the propulsion force and the drone adjusts the direction.

When approaching the target, the drone will release the missile and leave to save itself. Of course, it doesn’t matter even if it is accidentally blown up. The cost of drones is not high and they are consumables.

This drone refers to the Dragonfly drone of the Rising Sun Empire and the alien insects and self-destructing mosquitoes, and relies on its numerical advantage to carry out saturation strikes. Thousands are released at a time, leaving the enemy with nowhere to hide.

Boom boom boom, missiles explode one after another.

Most of the insects that were not shot down by infrasonic waves in the sky were Qila elite insects, and there were heavy casualties under the cover of missiles. The swarms of insects that were originally densely covered in the sky were soon cleared.
