Armor Frenzy

At the same time as the fierce confrontation on Duluo Island, a group of alien warships were quietly diving underwater not far from the east coast of Luzon Island.

In order to cover up their tracks, the alien warships sailed almost close to the seabed. Soon after, the batch of alien warships arrived at Luzon Island, some of the warships slowly floated up, and the remaining warships sank directly into the seabed.

After the alien warship surfaced, it immediately opened the hatch amid the surging waves, and a group of giant insects fluttered into the sky and rushed towards Luzon Island in groups.

At the same time, the underwater alien warships also released a group of aquatic giant insects. They looked very similar to lobsters. They sank into the water and waved two huge claws. They dug a hole on the seabed leading to the depths of Luzon Island.

The alien warship on the water just released the swarm, and the radar on the island found the abnormality in this direction, and immediately sounded the raid alarm.

The distance between Luzon and Duluo was only ten kilometers. Since the southeastern cluster encountered a raid by servants on Duluo Island, the entire island of Luzon was on the most alert, always vigilant for the swarms flying over the Duluo Strait.

It is very easy to fly across the strait, but the aliens plan to do this, but instead, they use the insect swarm on Duluo Island to drag the main force of the southeast group, and send another fleet to land on the east side of Luzon Island to prepare for The troops that defended the island were caught off guard.

The aliens were worried that the defenders on the island would be difficult to deal with, so they deliberately divided their troops into two groups. The group of giant insects in the air were basically cannon fodder, purely to attract the attention of the island defenders. The group of giant insects that burrowed in underwater , is the real main offensive force.

How could the defenders on the island know of the alien's plan? After discovering the swarm in the air, they immediately entered the first-level combat readiness, and the infrasonic cannon hidden in the jungle was immediately ready to fire.

Beidu is very clear that the capture of Luzon Island is not the goal. Guarding this island and preventing this island from being used by aliens is the real goal of the Southeast Cluster.

To this end, the military carried out a series of emergency measures after the Southeast Group took control of Luzon Island, building temporary sonic stations at various key locations, and using fixed infrasound weapons to control strategically important locations such as roads and beaches on the island.

Building a sound wave station is not an easy task. First of all, the infrastructure on the island is severely damaged and cannot be used at all. All the projects must be solved by the Southeast Cluster on its own.

In order to build a sonic defense system as soon as possible, the Southeast Cluster has adopted a series of powerful measures.

First of all, the main body of the building is poured with high-grade cement, and the construction standards refer to the fortress building to ensure the firmness of the sound wave station.

Secondly, each sound wave station is equipped with a set of power equipment composed of solar panels and high-density batteries. In order to prevent the sun from being absent for a long time in the rainy season, each sound wave station is also equipped with a diesel generator.

Again, place the infrasound generators far away from the sonic station. Each sonic station controls five to six generators. Calculated with an effective killing radius of five kilometers. After all the generators controlled by one sonic station are activated, it can control up to 400 generators. A huge area of ​​several square kilometers.

Note that the effective killing range of infrasound is not the absolute killing range, it is a combination of the absolute killing radius and the expulsion radius.

To put it simply, the target can be killed in a short period of time only near the sound source. After the distance is drawn, the sound wave will only make the target feel extremely uncomfortable, producing a strong expelling effect, and it must stay for a period of time before being injured by the sound wave.

Again, all sonic stations use radar control equipment, which, to put it simply, automatically activates the sonic cannon as soon as the radar is sent to the swarm.

In addition to the above preparations, each sonic station is also equipped with a class of guards, combining people and equipment to minimize the chance of errors.

Did the Youzhou battle group leave casually? Of course not. The reason why the Youzhou sailed south to Doluo Island was because the infrasound defense system on Luzon Island was initially established. Even if there were no mobile troops guarding it, the sonic station on the island could make the enemy have a good drink.

The Southeast Cluster has not been in control of Luzon Island for a long time, so it is impossible to build sound wave stations all over the island. The sound wave stations that have been built so far can only control key areas.

In other words, even if the sound wave station is used to cut the entire Luzon Island into several large pieces, and the whole island is blocked with points and areas, even if a swarm appears, it will not be able to break through the blockade of the sound wave station.

When the military is out, it will not be too late to build the sonic station all over the island.

But what does it matter? The sonic station standing in the jungle is like a nail left by human beings on the island. If aliens want to retake Luzon Island, they must first unplug the sonic station on the island. Split surround.

As expected by the military, after the insect swarm flew into Luzon Island, it immediately rushed to the nearest sonic station. Before it flew over the sonic station, the swarm crossed the radar warning line, and the automatic control system immediately activated the infrasonic cannon.

The flying height of the swarm is a bit low, just at the edge of the effective killing range of the infrasonic cannon. The sound wave failed to shoot down the giant worm, but forced the swarm to fly higher.

The insect swarm in the air really caught the attention of the defenders. No one thought that there was another group of giant insects underground, but the luck of the giant insect in the air was really bad. When it was about to fly over the sound wave station, a series of lasers fell in the air, killing all the giant insects above the clouds, and countless giant insects fell from the sky.

In order to expand the striking surface and increase the duration, Languan lowered the emission intensity of the laser cannon. The beam will not scorch the giant insect, but it can completely burn the insect's wings.

Anyway, the insects fly so high, it is definitely not good for them to fall from the sky.

The soldiers in the sonic station were observing the situation outside~www.readwn.com~ and suddenly found a group of giant insects penetrating the clouds, and then a large number of giant insects passed through the dark clouds like a torrential rain, and fell heavily into the not far away. in the jungle.

There was a series of dense explosions in the jungle in an instant, which was more lively than firecrackers on New Year's Eve.

The explosion was even more connected in the jungle, as if a whole cluster of bombs fell into the jungle at the same time, but in just a few seconds, a large area of ​​the jungle was emptied by the dense explosion.

The soldiers who witnessed this scene were horrified. No matter how strong the sonic station was, it could not withstand the continuous bombardment of so many giant insects. If the swarms were closer, they would just cover the sonic station...

Soldiers invariably fought a cold war.

After clearing the insect swarms over Luzon Island, the Languan ship covered Doluo Island again. This time, it was not so lucky. The falling giant insects were too dense, and Qi Jingwen's armored vehicles were destroyed several times by the intensive explosion. vehicle.

Across the dark clouds, there were very few giant insects that could find their target. All the destroyed vehicles were blind cats and mice. If the weather was clear, the loss of ground troops would definitely be more than that.
