All People Island: I Was Exposed To Build Civilization With Bare Hands

Two hours later.

near the sea.

Pieces of sea monster corpses have been floating.

The artillery fire continued to roar.

But the vanguard of the Kraken...

With the dense firepower, they killed the coast!

Yan and other members of the guard carried bazookas, concentrated their firepower, and immediately launched an attack.

Prioritize hitting the frontmost sea monsters.

"boom!"

The bazooka keeps firing.

The fallen sea monsters came one after another.

B...

The number of sea monsters did not decrease at all.

The sea monsters went forward one after another, as if they were crazy.

Continue to attack the defense line.

"Roar----"

The howling was getting closer.

Yan and the others endured tremendous pressure, and layers of sweat appeared on their foreheads.

But he gritted his teeth.

Not an inch back.

"Forty thousand sea monsters have been killed."

Qin Mu looked at the dense sea monster corpses in the sea, his expression became more and more serious.

The number of sea monsters.....

It completely exceeded the maximum limit that firepower could kill in a short period of time.

The remaining 60,000 sea monsters...

Following the vanguard troops, they landed on the island one after another.

Approaching the defense line.

1600 meters.

1500 meters.

1000 meters.

900 meters.

At 800 meters away from the defense line, Qin Mu sighed.

turn around.

A tightly closed cuboid iron box was taken out from the rear.

Give it to Yan.

Solemnly confessed: "Bury it 300 meters ahead, remember to handle it with care, be careful when you're kun.

Yan froze for a moment.

Subconsciously took the iron box and found that the iron box was unusually heavy.

I don't know what's inside.

"yes!"

He didn't ask much.

Nodding quickly, he picked up a shovel behind him.

With the iron box, he quickly approached the front.

Be careful all the way.

It took ten minutes.

It was buried 300 meters in front of the line of defense.

"Everyone, stop firing!"

Qin Mu took a deep breath and suddenly gave an order.

Yan and others heard the words.

Put away your weapons immediately and retreat quickly.

retreated within the line of defense.

"Roar-.._"

The sea monsters lost their firepower and charged faster and faster.

In an instant.

He rushed forward for hundreds of meters.

The line of defense is getting closer and closer.

Only less than a hundred meters!

close at hand.

The sea monsters opened their bloody mouths wide, their faces were ferocious, and their huge eyes were scarlet and bloodthirsty.

Scared Yan and the others so that their complexions turned pale.

Qin Mu is not in a hurry.

He walked up to a cannon, swung the muzzle direction, and fired a cannon at a distance of 300 meters.

"Boom!"

The sound of artillery was heard.

Directly killed dozens of sea monsters in that area.

Just when Yan and the others were full of doubts.

next second.

At 300 meters away, there was a sudden loud noise.

They just feel that their eardrums are about to be torn.

Followed by the fire that soared into the sky.

With the area 300 meters away as the center, it spread rapidly towards the surrounding area.

The terrifying shock wave carries a wave of heat

Rush towards the defense line.

Only for a moment.

Taking the 300-meter point as the center, Fang Yuan 100-meter sea monster melted in an instant!

The sea monster a hundred meters away...

Under the cover of the shock wave, they all died on the spot!

A mushroom cloud......

It rises slowly from 300 meters away and soars into the sky.

After a few minutes.

Yan and the others regained their sense of hearing, and looked at the scene in front of them in shock.

A huge sinkhole appeared right in front of the line of defense.

One hundred meters in diameter.

Fiù...

Even as deep as 30 meters!

Before their eyes, they could no longer see the ferocious figure of the sea monster.

The sea monster that has not yet washed ashore...

It seemed that he was also stunned by the terrifying explosion, and forgot to charge for a while.

"This... this... this..."

Yan's pupils shrank sharply.

His body trembled, and he stuttered again.

Reminiscent of the cuboid iron box that Qin Mu asked him to bury earlier...

I couldn't help being afraid for a while.

The cannon that was fired just now seemed to be the cuboid iron box that detonated!

He never dreamed...

That small cuboid iron box has such terrifying power!

"I didn't expect the RDX high-energy explosives to come in handy so soon."

Qin Mu put his hands behind his back and his eyes flickered slightly.

This explosion in front of me...

It was triggered by the cuboid iron box, which contained ten kilograms of RDX.

not long ago.

When the era of sea island industry started, he exchanged 20,000 survival points for RDX in the system mall.

This explosive...

It is more intense than TNT, and the energy generated when it explodes is twice that of TNT.

And has a very high detonation speed, up to 8 kilometers per second.

But the first cosmic velocity is only 7.9 kilometers per second.

In other words, as long as it explodes, the destructive power can reach eight kilometers away in one second.

Unless it can transcend the speed of the universe in an instant.

Otherwise it must be covered by it!

And its power......

It is twice the size of TNT, with a small body and a large burst of energy.

A small piece of soap-sized RDX can instantly blow up a building or a warship!

It is extremely unstable at normal temperature and pressure.

Very easy to detonate.

That's why it's called a high-energy explosive!

Nuclear warheads or missile heads usually use it as the main component.

In the cuboid iron box he handed to Yan just now, there was actually only ten kilograms of RDX.

The only pity is that...

He does not have the precise guidance technology for missile launch now, so he cannot launch the missile made by Hessokin.

This primitive method can only be used to bury explosives in advance.

And [Precise Guidance Technology] needs to climb to the next stage of civilization before it can be exchanged and used to exert the greatest power of RDX.

$71...

Although there are many sea monsters, their IQs are not enough.

40,000 sea monsters were killed in one blast, and 20,000 remain..."

Qin Mu glanced near the sea and estimated the number of remaining sea monsters.

There are less than 20,000 left.

The originally overwhelming and densely populated offshore area was instantly emptied a lot.

With the firepower covered by internal combustion engine semi-automation

You can totally kill them all!

at the same time.

Branch (Zhao Li's) technology city.

The indigenous residents who were working also heard the deafening explosion.

The whole island seemed to be shaken a few times by the shock.

"what happens?"

Many natives were terrified and couldn't help but look in the direction of the explosion.

I happened to see a mushroom cloud rising slowly.

Extremely shocking.

"Could it be a sea monster landing on the island?"

The people from the Stone Tribe were so frightened that they couldn't help but fled from the workplace.

Out of the science and technology city consciousness.

Sneak towards the coast.

What they think is that if the line of defense falls, they will escape first.

The island is nice, but they don't want to be stranded in the city and become their dinner.

TO......

After they sneaked close to the coast, they saw a horrifying scene of a 100-meter giant crater.

There are sea monster corpses everywhere.

The line of defense remained motionless, as stable as Mount Tai.

The sea monsters in the distance seemed to be scared out of their wits, and they didn't dare to attack for a while.

Has been wandering near the sea!.
