The Marines hurriedly retreated.? ?? ．?

They are as far away from the cave walls as possible.

All kinds of weapons are on standby.

The loosening of the soil is getting stronger and stronger.

Immediately, a praying mantis creature suddenly emerged.

Good guy, it's actually a super large praying mantis creature, and it feels like it's three or four stories tall.

Wang Buyan frowned secretly.

A bad feeling arose.

The praying mantis creatures that appeared on the ground before were not particularly large.

But now all I see are behemoths.

Could it be that they have evolved again?

"Puff puff!"

"Puff puff!"

Without thinking, various weapons opened fire quickly.

As a result, the praying mantis creature that had just been drilled out was immediately burst into the brains of the beating, and its skin was opened.

However, its inertial impact still threw several fighters to the ground.

Sharp claws, grabbed the warriors.

Fortunately, thanks to the helmet and body armor, I was not seriously injured.

"Retreat!"

"Retreat!"

Li Mu quickly issued an order.

However, it was monitored from the rear that there was frequent movement in the underground soil.

It is estimated that there are a lot of praying mantis creatures trying to get out.

In the narrow cave, the special combat team is surrounded by enemies on all sides! It is easy to fall into a heavy siege.

Fortunately, the retreat was timely, so there were no casualties.

However, this is tantamount to declaring the failure of the underground operation.

Those damn praying mantis creatures also seem to have some wisdom. Do you know how to lure the enemy deeper?

Especially their ability to drill into the ground is so strong, it is completely unexpected!

On the ground, in the air, it's the human world.

However, when it goes underground, it is the territory of praying mantis creatures.

Various monitoring shows that deep underground, at a distance of 300 meters to 500 meters, various vibrations are frequently heard.

Apparently, there are a lot of praying mantis creatures that are burrowing.

"Where's the big burrowing bomb?"

"On the way. ”

"Good. ”

Half an hour later, the ground-penetrating bombs arrived on the battlefield.

This is a specially made super ground-penetrating bomb that weighs more than eight tons.

It will be dropped from a height of three thousand meters, burrowed deep underground at terrifying speeds, and then detonated.

It can shoot through five meters of reinforced concrete, or thirty meters of ordinary dirt surface.

However......

Facing 300 meters underground......

Wang Buan still feels powerless!

At 300 meters underground, even a super-large nuclear bomb may not be able to reach it.

After all, the dirt is too thick. The defense is too strong.

To say what is the strongest defense in this world.

One is water.

One is soil.

The soldiers will block, and the water will cover the earth, this is not a joke.

The only thing that can destroy the soil is water. And the only thing that can destroy water is soil. No other mission weapon can do it.

No matter how powerful a nuclear bomb is, it can't blow through the earth's crust. Being able to blast out a 150-meter-deep crater is already very powerful.

But an earthquake can change the terrain and landscape.

As for ordinary conventional bombs, being able to blow up a pit a hundred meters deep is already the sky.

Of course, an eight-ton ground-penetrating bomb can still flatten a radius of thousands of meters.

As long as all living things are within this range, there are no corpses.

"Boom!"

"Boom!"

Sure enough, a continuous explosion was heard.

But the ground was overturned. A huge mushroom cloud appeared.

Wang Buan shook his head secretly.

The effect is not ideal!

It is estimated that it is a pit of about 100 meters.

For spaces below 300 meters, there should be no damage. I have more than enough heart, but not enough power.

Sure enough, not long after, a message came from ahead.

The effect is average.

To read it in depth is to be ineffective.

"I guess I should use a cloudburst bomb. ”

"Cloudburst bombs are coming soon. ”

Sure enough, a few minutes later, a heavy cloudburst bomb was dropped.

This is a three-ton cloudburst bomb, which is almost out of the scope of tactical weapons, and can almost be classified as a strategic weapon.

In terms of destructive effect alone, it is more powerful than a ground-penetrating bullet.

"Boom!"

"Boom!"

Sure enough, the explosion of the cloud burst bomb lasted for a long time.

However, the cloud burst bomb exploded in the depths of the cave, and the power will become more and more powerful, constantly spreading to the depths of the cave.

However, after ten minutes, everything was calm.

It is not clear exactly how effective it will be.

In short, the underground mantis biological activity has not stopped.

It's depressing.

Still haven't done it.

Is there nothing that can be done about it?

Suddenly, Wang Bu'an felt that the earth was still very dangerous.

How so?

There are still a lot of dead ends!

For example, at depths of less than a thousand meters in the ocean. Humans can't attack.

In addition, deep underground below 500 meters, human beings have no effective weapons to deal with.

If these places are occupied by the enemy, we can only stare dryly for the time being.

On the sea, you can have countless warships cruising.

At depths of the ocean of 300 meters, 500 meters, 700 meters, submarines can also go on a rampage.

However, if this depth exceeds a thousand meters, all weapons will be disabled.

Similarly, in the face of the "alien creatures" hidden 500 meters underground, all weapons are also ineffective.

What does this mean?

This shows that humanity does not have complete control over the planet.

There are many, many places on Earth that are beyond the reach of human beings themselves. It is the "soft underbelly" of humanity.

The technology is not advanced enough.

Industry is not strong enough.

In terms of the tech tree, there is still a lot of room for improvement......

"Chief Engineer Wang!"

"Minister Liu!"

When he was watching the video, Liu Zhenhua came quietly.

He invited Wang Buan to the test site.

"Do what?"

"Set off a big firework. ”

"Super Bomb?"

"Yes. ”

Wang Bu'an heard the song and knew the elegance.

The large fireworks of the Air Force Rabbit must be a special super aerial bomb.

To be exact, it should be more than ten tons of aerial bombs. It is mainly used to cooperate with the Bull Demon King transport aircraft and Mrs. Zhurong bombers.

Of course, the Tyrannosaurus rex helicopter and the sword rex helicopter can also be hovered at high altitude.

Previously, such super-large aerial bombs were almost useless.

Why?

It's too powerful!

Where can you put it?

Well, now, the appearance of the praying mantis creature has given the super aerial bomb a chance.

"What's the situation outside?" asked Wang Buan.

"Very bad. Liu Zhenhua's face was quite gloomy.

"What's wrong?"

"Praying mantis is overflowing!"

Liu Zhenhua briefly introduced that similar mantis creatures have appeared all over the world.

The location of their appearance seems to be random. Not at all sure.

Most of the praying mantis creatures have suffered devastating blows.

All countries have concentrated their most elite military forces to strike at them in all directions.

However, there is always no eradication.

Their ability to drill holes is too strong.

They are hidden hundreds of meters deep underground, making people helpless.

Especially in Africa, it is almost like no one. It feels like Africa is going to be taken over by them.

It is said that the United Nations is going to meet again to discuss ......

However, everyone knows that the United Nations is an ornament.

In the end, it will be up to each country to do it with real knives and guns. There is no need for delay.

The longer the delay, the greater the number of praying mantis creatures. Its individual combat effectiveness is likely to increase.

The most important thing is that there is no fundamental conclusion in the study of praying mantis biology.

Is it a carbon-based organism at all?

Does it need oxygen?

How does it reproduce?

What is its main food?

There are several fundamental questions that have never been answered.

This means that there is no completely effective way to eliminate the other side. It can only be a simple piling up of military power.

At present, all countries are moving out of their stockpiles of weapons and putting them in one go.

Whether it has an effect or not, let's blow you up first.

"It's here. ”

"Look. ”

The two went outside.

A Bull Demon King transport plane is docked here.

It was modified, with two super bombs installed in the cabin.

The total mass of each bomb is twelve tons. Eight tons of charge. Looking at the world, it is the largest number of aerial bombs with ordinary charges.

However, these are the beginnings. There are also larger bombs in the works.

Twenty tons, thirty tons, fifty tons......

Or even hundreds of tons!

"Three hundred meters minimum. ”

"Up to 30,000 meters. ”

Liu Zhenhua said simply. Wang Bu'an said the data is good.

Both of these data are the height at which the bomb was dropped. Among them, the highest is 30,000 meters, and the lowest is 300 meters.

"Let's go!"

"Okay. ”

Wang Buan boarded the plane.

Liu Zhenhua also boarded the plane. There are a few others.

The Bull Demon King transport plane will fly to the war zone and drop bombs on the spot.

However, this war zone is not Qiangtang. It's somewhere abroad.

The military force in this area is too weak to deal with the mantis creatures that suddenly appeared, so they can only ask Huaxia for military assistance.

After informing the United Nations and obtaining authorization from the United Nations, Huaxia sent reinforcements.

The first to act were two squadrons of fighters.

A squadron of J-11 fighters.

A squadron of J-16 fighters.

They swooped down from a high altitude and dropped thousands of tons of ammunition.

Among them, more than 80 large five-ton aerial bombs were dropped in one go.

All the praying mantis creatures that appeared on the ground were swept away by Huaxia's fighter jets. The remnants have taken refuge in underground caverns.

This 12-ton super bomb is designed to deal with targets deep in caves.

How effective is it? Let's test it first.

"Target locked. ”

"Delivery. ”

Soon, the transport aircraft entered the theater of operations.

After the target is determined, the super aerial bomb is manually dropped.

This big guy weighing 12 tons pushed down with a robotic arm. 1500 meters above the ground.

In less than a minute, a deafening loud bang was heard on the ground.

Obviously, this is a super bomb that exploded.

It set off a huge mushroom cloud that made people's hearts palpitate.

But......

The results are not encouraging.

As a result of the reports of the ground forces, the effect of the blasting was mediocre.

It can only reach a depth of 200 meters underground. It has little impact on the area of 300 meters or 500 meters underground.

Wang Buan subconsciously frowned.

The bomb had no effect.

What to do?

Do you want to use an excavator?

Do you want to use an excavator to dig out the mantis creatures?
