In short, once they enter the combat posture and have people in the combat positions, these vehicles can immediately transform from transportation vehicles into war fortresses.

Just as Zhou You and Deng Tao speculated, after the rats digging in the mountain realized that their actions had been exposed, in addition to trying to kill the spy Yin Yan but failing, they did take other actions.

Rats have become more efficient at transporting soil.

In addition, there were indeed a small number of rats that looked more elite and began to move along the ground in the distance. They probably wanted to verify how many human troops were coming and whether these humans were elite.

Yin Yan, who was low in the sky, saw clearly the movements of the rats and immediately reported them back.

On the human side, the drone squadron that took the lead immediately received new instructions.

Their new mission is to kill the rat spies and blind the eyes of the rats to prevent the rats on the mountain from escaping early.

The drone squadron immediately dispersed and advanced in a straight line at low altitude.

Each drone is kept about twenty meters away from each other.

A total of twenty drones formed a horizontal formation about 400 meters long, with a height of about five meters above the ground.

Such a formation would allow these elite combatants to use their naked eyes to spot all the rats' spies.

After just five minutes, they were divided into three teams. Each team's reconnaissance team, consisting of about ten elite rats, was completely wiped out, and not one of them escaped.

At this time, the fleet of three hundred single-person airships had all taken off and were advancing towards the hill in a denser formation.

The three Langya No. 4 airships have also been fully deployed and are about to take off.

As for the ground troops, their movements are not slow, even faster than the Wolf Fang airship.

The average advancement speed of ground troops is about two meters per second in long-term rapid marches, advancing about 120 meters per minute.

Only five minutes have passed, and the ground troops have advanced 600 meters and are expected to arrive at the bottom of the hill in twenty minutes at the latest.

By that time, the drone squadron must have finished pouring gasoline and returned to replace the ammunition reserve type.

Some of the Langya 1 single-person airships should have started dumping gasoline at about the same time.

There are also some single-person airships with particularly high pilot skills, which should almost reach the base where the rats are hollowing out the foundation.

As for Langya No. 4, due to its large size after deployment, it is inconvenient to turn. The steering is not as flexible as a single-person airship. Moreover, the skeleton structure of the detachable airbag uses aluminum alloy, a material that is easy to conduct electricity. It is rashly close to high voltage.

Electric towers may suffer from breakdown effects, posing greater safety risks.

Therefore, the main task of the Langya 4 airship is to use its stronger carrying capacity and faster speed combined with the dual power of manpower and electric drive to first go to the back of the hill. One is to observe the terrain, and the other is to detect possible dangers of mice

Choose an area to escape and pour gasoline on it in advance.

Unfortunately, it is a relatively hot summer. It rained heavily a few days ago and the air humidity is high. Therefore, if you want to set fire to the mountain, you really have to rely more on a large amount of gasoline to heat up in advance.

If it is a dry winter, the cost of setting fires will be much lower.

But there is no way now.

The only good news is that due to the continuous sun exposure, the ground has been dry enough, and some parts of the ground have even been exposed to the sun to the point of cracking.

Another five minutes passed, and the drone squadron had replaced its equipment and ammunition, turned into a pure long-range killing mode, and started firing again.

This time the main mission of the drone squadron became to kill the rat spies.

In front, airships No. 1 and 4 have arrived at the bottom of the hill one after another and begun to take their positions.

However, the various flight units did not start pouring gasoline at this time, and were only circling and observing in the air.

In another ten minutes, the ground troops will arrive at the foot of the hill.

Zhou You gave the order, and many flying units began to pour gasoline.

In just three minutes, more than 300 flight units poured gasoline into a circular line with a total length of more than three kilometers, which happened to be a line at the foot of the hill.

After the outer layer of gasoline was poured, the low-speed air units immediately took off and left. The drone warriors carrying a small number of rockets slightly lowered their altitude and approached these oil lines.

Immediately afterwards, the soldier on the drone lit the rocket and shot it out lightly.

The flaming rocket drooped to the ground and immediately ignited the gasoline.

Watching the flames at the foot of the mountain spread rapidly, more than ten single-person airships suspended above the base immediately poured gasoline.

The gasoline happened to be sprinkled on the area below where the rats had made dense rat burrows.

Yin Yan, who had been waiting for a long time, shot several arrows accurately in succession.

Dots of fire spots sprinkled down, like barnyard grass seeds sprinkled in early spring.

Then the seasons changed, and in an instant blue and orange barnyard grass grew all over the mountain.

This area immediately burst into flames.

The mice near the hole immediately became confused and began to wander around like headless flies.

But the chaos only lasted a very short time, and the mouse outside the hole suddenly froze, as if it had received a new order at the same time.

The mice immediately turned around and ran into the mouse holes they had dug.

At this time, Yin Yan was controlling the drone to rise in height, and dodged to the side directly above the flames to avoid being caught by the rising thermal air.

Of course, Yin Yan did not forget her reconnaissance mission. She kept her eyes on the ground and just used the corner of her eyes to observe the general environment around her.

Now that her height has reached above the tree canopy, her main defenses are wires and the one-man airships of other comrades.

Yin Yan was minding her own business, complaining on the intercom, saying that even if these mice hid in the ground, when the mountain fire really burned out, they would still be able to burn the cave into a vacuum.

The rats inside will most likely die from lack of oxygen.

This kind of hiding makes no sense at all.

Zhou You and Deng Tao were thinking the same thing.

But soon the mouse in the hole slapped Yin Yan in the face.

About thirty seconds later, a mouse's head emerged from the first hole below.

As soon as the mouse poked its head out, it was immediately burned by the flames next to the hole, causing its hair to curl violently, and the pain made it squeak.

If the mice at this time were still ordinary animals in the past, they would inevitably succumb to their animal instincts and shrink back into their burrows, just like an ostrich that buries its head in the sand but exposes its butt when it is in danger.

There is no difference between self-deception and others' escape.

Even though the temperature in the cave will indeed be relatively low at this time, as time goes by, the air in the cave will indeed be taken away by the rising thermal airflow.

Even if the mouse in the hole continues to burrow deeper, and then buries itself in soil to isolate itself from the high temperature as much as possible, and seeks air from the gaps in the soil as low as possible, the mouse in the hole will still die of suffocation.

There is not one out of ten.

However, now this mouse immediately showed something unusual.

It actually jumped out of the hole against the high-temperature flames, then pressed its chest and abdomen to the ground and sprinted forward along the sea of ​​​​fire composed of burning gasoline immersed in the surface of the soil.

This guy actually knows that the temperature of the flame inside the flame is relatively low, which can support it to run farther.

But it still failed to succeed.

Even if the temperature of the inner flame is slightly lower, it is not something that animals can withstand.

It only ran about three or four meters, and then fell head-on to the ground.

At this time, all the hair on its body had been burned away, and the surface of its body had begun to bubble with frying oil in the flames.

But its desperate charge was not in vain. On the road it stepped on with its four legs, the height of the flames became shorter.

At this time, Yin Yan in the sky understood that this mouse was putting out the fire.

But unlike humans who always subconsciously look for water or sand or other things to put out the flames when faced with a fire, this mouse used the stupidest of stupid methods, which was to use the hair on the bottom of its body to soak up the gasoline.

to reduce the intensity of the fire.

After the mouse fell, the next mouse immediately followed.

Unlike the first one, this mouse is covered with a thin layer of slightly moist new underground mud.

However, this new layer of mud seems to have little effect.

As the mouse ran, the soil kept falling. Before the mouse could run far, which was less than two meters away, almost all the new mud had fallen.

This second one stepped on the traces of the first one, and also rushed forward, and rushed over the body of the first one. In the end, it rushed forward another two meters.

The moment the second one fell, the third one appeared again.

Unlike the first two, this third one was actually dragging a fully loaded wooden cart.

Previously, Yin Yan had noticed that the mice that pulled the wooden cart out of the hole were taking very cautious steps, for fear that the soil in the wooden cart would accidentally be lifted up and dumped on both sides of the hole.

But the third mouse did the opposite, running very fast, as if deliberately spreading dirt to both sides.

The third mouse didn't make it far, and barely reached the spot where the second mouse fell. Then it also rolled into the sea of ​​fire and turned into a teppanyaki.

But the third mouse has left the most results so far.

At this time, the wooden cart that was making loud noises and bursting with flames was already empty.

The soil was thrown unevenly on both sides of the road that the two mice in front had worked hard to cut out, slightly blocking the fire, and barely gaining access to life for the group of mice who were still stuck in the hole.

During this period, Yin Yan in the air also tried to shoot to hinder the mouse's movement, but unfortunately the flames caused the density of the air to change. When light passes through air of different densities, refraction occurs, similar to water flow.

But this refraction is more complex and irregular.
