1816 Counterattack on Luzon

While the fierce battle was taking place on Duluo Island, a group of alien warships were quietly snorkeling 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 bottom of the sea. Soon after, these alien warships arrived at Luzon Island. Some of the warships slowly surfaced, while the remaining warships sank directly to the bottom of the sea.

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

At the same time, the underwater alien battleship also released a group of giant aquatic insects. They look very similar to lobsters. They sink to the bottom of the water and wave two huge claws. In a few clicks, they dig a burrow into the bottom of the sea that leads to the depths of Luzon Island.

As soon as the alien warship on the water released the insect swarm, the radar on the island discovered anomalies in this direction and immediately sounded the raid alarm.

Luzon and Duluo are only a dozen kilometers apart. Ever since the Southeastern Cluster encountered a surprise attack on Duluo Island, the entire island of Luzon has been on the highest alert, always wary of insect swarms flying across the Duluo Strait.

It is very easy to fly across the strait, but the aliens plan to do this. Instead, they will use the insect swarm on Duluo Island to hold back the main force of the southeast cluster, and send another fleet to land on the east side of Luzon Island in preparation. The troops defending 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 giant insects in the air were simply cannon fodder, purely to attract the attention of the island defenders. The giant insects burrowed and infiltrated underwater. , is the real main offensive force.

The defenders on the island did not know the aliens' plans. After discovering the insect swarm in the sky, they immediately entered the first level of combat readiness, and the infrasonic cannon hidden in the jungle was immediately ready to fire.

Beidou is very clear that capturing Luzon Island is not the goal. Guarding this island and preventing it 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 Cluster took control of Luzon Island. It built temporary acoustic stations at various key locations and used fixed infrasonic weapons to control roads, beaches and other strategic locations on the island.

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

In order to build an acoustic 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 solidity of the sonic station.

Secondly, each acoustic station is equipped with a set of power equipment composed of solar panels and high-density batteries.

In order to prevent the rainy season from being out of the sun for a long time, each sound wave station is also equipped with a diesel generator.

Thirdly, place the infrasound generator far away from the acoustic station. Each acoustic station controls five to six generators. Based on the effective killing radius of five kilometers, after all the generators controlled by one acoustic station are started, it can control up to 400 A huge area of ​​more than square kilometers.

Note that the effective killing range of infrasonic waves is not the absolute killing range. It is a combination of the absolute killing radius and the expulsion radius.

To put it simply, only when the target is near the sound source can the target be shocked to death in a short period of time. After the target is further away, the sound wave will only make the target feel extremely uncomfortable and produce a strong expulsion effect. The target must stay for a period of time before being injured by the sound wave.

Again, all sonic stations use radar control equipment. To put it simply, once the radar is sent to the insect swarm, the sonic cannon will be automatically activated immediately.

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

Did the Youzhou battle group leave casually? Of course not. The reason why the Youzhou went south to Duluo Island was because the infrasonic defense system on the island of Luzon was initially completed. Even if there were no mobile troops to guard it, the sonic station on the island could give the enemy a good drink.

The Southeast Cluster has only been controlling Luzon Island for a short time. It is impossible to build sonic stations all over the island. The sonic stations that have been built so far can only control key areas.

In other words, the sound wave station is used to cut the entire Luzon Island into several large pieces and block the entire island from point to area. Even if a swarm of insects appears, it cannot break through the blockade of the sound wave station.

It won't be too late to build sonic stations all over the island once the military takes over.

But what does it matter? The sonic station standing in the jungle is simply a nail left by humans on the island. If the aliens want to take back Luzon Island, they must first unplug the sonic station on the island. Otherwise, no matter how many bugs there are, they will only be captured by the troops defending the island. Split surround.

True to the military's expectations, after the insect swarm flew into Luzon Island, they immediately pounced on the nearest sonic station. Before they could fly over the sonic station, the insect swarm crossed the radar cordon, and the automatic control system immediately activated the infrasonic cannon.

The flying height of the insect swarm was 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 insect, but only forced the insect swarm to fly higher.

The swarm of insects in the air did attract the attention of the defenders. No one thought that there was another group of giant insects underground. However, the giant insects in the air were really unlucky. They happened to catch up with the Languan flying over Luzon Island, and right before the swarm of insects. When they were about to fly over the sonic station, a series of lasers fell from the sky, killing all the giant insects above the clouds. Countless giant insects fell from the sky.

In order to expand the strike surface and increase the duration, the Languan reduced the intensity of the laser cannon. The beam would not burn the giant insect, but could completely burn the insect's wings.

Anyway, the bug flies so high that it would definitely not be good if it fell from the sky.

The soldiers in the sonic station were observing the situation outside when they suddenly discovered a group of giant insects penetrating the clouds. Then a large group of giant insects penetrated the dark clouds like a heavy rain and fell heavily into the jungle not far away.

A series of dense explosions instantly erupted in the jungle, which was more lively than setting off firecrackers on New Year's Eve.

The explosions were connected together in the jungle, as if a whole group of cluster bombs fell into the jungle at the same time. However, in just a few seconds, a large area of ​​the jungle was cleared by the dense explosions.

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

The soldiers shuddered in unison.

After the Languan cleared the insect swarm over Luzon Island, it covered another wave of Duluo Island. This time, it was not so lucky. The falling giant insects were too dense. Qi Jingwen's armored vehicles were destroyed several times by the intensive explosion. vehicle.

Across the sky full of dark clouds, there were very few giant insects that could find their target. All the destroyed vehicles were the result of a blind cat hitting a mouse. If the weather was clear, the losses of the ground troops would definitely exceed this.
