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

...

island.

On the tower.

Qin Mu also noticed the sudden appearance of ten sea monsters, showing surprise.

These ten sea monsters...

Seems to be looking at him.

There was a gleam of wisdom in his eyes, which was very different from the sea monsters he had encountered before.

"Non-my family, its heart must be different!"

Qin Mu snorted coldly and didn't care so much.

Adjusted the muzzle.

He simply pulled the trigger directly, and shot wildly at the ten sea monsters who suddenly appeared to watch the excitement.

"Da da da--"

The machine guns kept firing, bursting into flames.

His newly developed weapon is called the Burst Burst Gun.

He spent 1,000 survival points to purchase the manufacturing blueprints, and it took several days to manufacture them.

By pulling the trigger and bumping the way...

It can shoot continuously, which is more convenient and convenient than the flintlock.

The rate of fire is also more amazing.

The shooting range is also farther, reaching 300 meters.

These ten spectator sea monsters...

Naturally, it was also within range, so he simply acted first.

However……

After the burst firing gun fired a round.

He found that the ten sea monsters outside the city were unscathed!

through the telescope.

He could see that many bullets hit them, but they were all bounced off by their blue scales.

"Defense... so strong?"

Qin Mu's pupils shrank, startled by their defense.

This world is indeed extraordinary.

There are actually creatures that can resist bullets!

"Roar--"

And those ten sea monsters seemed to be completely angry after being provoked.

There was a terrifying roar.

Jump up.

Stepping on the corpses of countless sea monsters, they rushed towards him.

Extremely fast.

Can only vaguely see afterimages!

"Squeak——"

The monkeys behind Qin Mu heard the roar.

He was so frightened that he was paralyzed, curled up on the ground and trembling constantly.

in an instant.

The afterimages of these ten sea monsters surpassed the corpses of two thousand sea monsters.

The distance from the city wall is getting closer and closer.

After a few seconds.

The ten sea monsters were only 20 meters away from Qin Mu!

It only takes two seconds to jump onto the city wall!

On the tower.

Qin Mu stood where he was, but didn't move a muscle.

His gaze remained on the afterimage.

"Roar--"

The ten sea monsters roared again, showing ferocious expressions.

In their eyes, Qin Mu is already in their pocket.

However……

next second.

"boom!"

Under their feet, a terrifying flame rose into the sky.

There was a huge explosion.

Swallow all ten afterimages.

After a few seconds.

After the light dissipated, a huge tiankeng appeared on the ground.

Twenty meters wide!

Ten meters deep!

Ten second-order sea monsters...

Disappear out of thin air!

...

Jiang Cheng University.

Island observation room.

There were the sounds of tutors swallowing saliva everywhere.

Including Li Songdao, everyone's eyes widened, staring at the tiankeng that appeared out of thin air.

Silence!

At the last second just now, the afterimages of the ten sea monsters were about to approach Qin Mu.

But……

The scene they imagined Qin Mu being torn apart did not happen.

Instead, there was a terrifying loud noise outside the city, and the entire island seemed to tremble.

Then this huge tiankeng appeared in front of me!

Twenty meters wide.

Ten meters deep!

The city walls built by Qin Mu were even blown out of their foundations.

shocking!

After a while.

The instructors glanced at each other and couldn't help talking.

"What happened just now? Where did the ten second-order sea monsters go?"

"What did Qin Mu do again? What happened?"

"Is it gunpowder? Wouldn't the ten sea monsters be killed?"

"It should not be dead. If it is dead, at least there will be a corpse. There is nothing in the giant pit."

"..."

The loud noise just now and the sudden appearance of the tiankeng in front of them startled all of them.

This power...

Created a tiankeng out of thin air, which is already equivalent to a full-strength blow of the third order!

Many mentors instantly thought of the gunpowder that Qin Mu used before.

Before there was no artillery.

Qin Mu planted a large amount of gunpowder to make traps to hunt sea monsters.

"No, not gunpowder."

Li Songdao recovered from the shock and shook his head: "The power of gunpowder is not that great, unless he buried a million tons at the foot of the city wall."

He has some research on weapons in the technological age.

The power of gunpowder is extremely limited.

It is difficult to blow up the tiankeng in front of you at once, unless Qin Mu is so mad that he buries a million tons of gunpowder.

but……

It is estimated that there are not so many gunpowder making materials on the entire island.

"It's TNT."

The vice-principal at the side suddenly spoke, and said with certainty: "Before I became an island owner, I liked to study these old-age weapon knowledge. This is definitely TNT!"

Everyone heard the words.

They looked at him one after another, but they didn't understand what TNT was.

"To put it simply, TNT is an upgraded version of gunpowder, also known as the king of explosives!"

The vice-principal smiled wryly, and then explained: "One kilogram of gunpowder can only explode a boulder, but one kilogram of TNT can instantly generate 4.2 million joules of energy."

"That is to say, it can cause a one-kilogram object to have a displacement of 420 kilometers, and it can instantly raze a three-story concrete building to the ground!"

Speaking of which.

He glanced at Qin Mu who was standing motionless on the tower.

The expression was a bit complicated: "Based on the current power of the tiankeng... Qin Mu used about ten kilograms of TNT."
