Goblin: My descendants are all over the world

Because the breech block has the highest strength requirement.

Chapter 248 Rune Magic Circle

The main function of the gun body and muzzle is to relieve pressure.

Therefore, the pressure will be much lower.

With a good start, all that’s left is to optimize.

"Boys, let's go back!"

Li Meng carried the magic cannon and walked in the direction they came from.

In the next few days, Li Meng only did one thing.

That is to repeatedly optimize the data of the magic cannon.

Five days later, the roar of artillery fire was heard again deep in the forest.

The forest where the test site is located has long been in ruins.

A large number of trees fell in the forest.

This time the shelling continued for more than half a month.

It's a new day, morning.

In the testing ground, Li Meng stood next to a huge and heavy magic cannon.

The magic cannon has a caliber of 200 mm.

The thickness of the muzzle and barrel reaches 300 mm.

The diameter of the entire muzzle and barrel reaches 800 mm.

The entire gun barrel is about five meters long, and the diameter of the breech reaches three meters.

"Such a massive vessel would require very high structural strength."

Li Meng was a little skeptical whether the wooden ship could really bear the weight of the magic cannon?

"It seems we need to thicken the structure of the floating battleship and the gun deck."

However, Li Meng did not intend to stop the construction of the first airship.

The first airship was an experimental prototype.

It will be redesigned based on demand later.

Li Meng squatted down and picked up a shell from the ground.

The next step is to make explosive shells.

Although it is easy to say, it is very difficult to do.

The magic in this world is omnipotent.

But how to make multiple rune magic circles work together is a big problem.

Li Meng and Xiaobai discussed for several days and nights when engraving the rune magic circle inside the barrel.

Finally, it was decided to use a combination of seven rune magic circles.

The seven rune magic circles are the explosive fireball rune, the magic transfer rune, the magic constraint rune, the magic barrier rune, the magic amplification rune, the magic strengthening rune, and the magic energy gathering rune.

You can make the magic cannon yourself.

After all, the task of casting cannons can be left to the goblins.

I just need to do the final carving of the rune magic circle.

But as consumables, shells are better for the general public.

Li Meng has no intention of becoming a slave to war.

A lifetime of hard work making shells.

Therefore, the production of artillery shells must be simplified.

And you can't use mithril to carve rune magic circles.

Mithril is too valuable and it would be a waste to use it on artillery shells.

"Go, go back!"

Li Meng carried the magic cannon and left the messy testing ground.

In the months that followed, the forest outside the Iron Cave fell silent.

Li Meng was concentrating on studying the method of making explosive shells in the iron cave.

"Woof woof, go play somewhere else, boss, I'm busy!"

In the afternoon, the underground riverbank of Tiedong Cave.

Li Meng sat on the shore, staring at the big iron ball in his hand in a daze.

Wangwang on the side rubbed Li Meng's thigh.

Wangwang had returned several months ago.

This added a group of jumping Squiggs to the Iron Cave.

Squig loved the hot iron caverns.

There are fire crystals in the iron cave, indicating that it is a place where the fire element is deposited.

As a fire-attributed monster, Squig naturally likes such an environment.

"Woo!"

It barked a few times, then jumped away.

Looking at the big iron ball in his hand, Li Meng sighed in his heart.

There were difficulties in making the shells.

Following Xiaobai's suggestion, Li Meng mixed fire crystal powder and water slime to create an enchanted liquid.

Although the superconductivity of the enchanting liquid is not as good as mithril.

But it’s not unusable.

But the only drawback of this enchanting liquid is its instability.

"Roar!"

At this moment, a barking sound suddenly sounded behind him.

Li Meng looked in the direction of the sound.

I found that Wangwang accidentally bumped into a rock.

The body subconsciously swells.

The body grew bigger and bigger, and eventually became a giant with a diameter of five meters.

This scene made Li Meng's eyes light up.

Looking back at the cannonball in his hand, Li Meng's eyes lit up.

"Since the delay fuse doesn't work, let's use the collision fuse."

Although the structure of the collision fuse is more complicated.

But there is a way to simplify it.

The instability of enchanted liquid is the best thing to make a collision fuse.

Li Meng, having an idea, stood up.

He hurried to his alchemy table.

In the following months, Li Meng did only one thing.

That is to simplify the production process of artillery shells.

One afternoon four months later.

The most important experiment was officially launched at the test site.

This time, an artillery platform appeared in the test site.

The ground was paved with thick wooden boards.

The magic cannon also made a steel gun mount with a pulley.

Li Meng took a cannonball with a fiery red rune magic circle engraved on its surface and stuffed it into the muzzle of the cannon.

The shells are not solid, they are hollow inside.

There is a fire crystal inside.

The fire crystal inside only acts as something like explosives.

When the strength of the force applied to the shell exceeds a certain upper limit.

The explosive rune magic circle on the surface of the shell will be activated.

This activation is achieved by relying on the instability of the Fire Crystal.

Once the shell explodes, the fire crystal inside will be detonated.

The intensity of the explosion is related to the size and magic value of the fire crystal.

My dear, there is more to come after this chapter. Please click on the next page to continue reading. There will be more exciting chapters later!

"Everyone, stand back, or you'll die!"

Li Meng waved his hand and drove away the goblin minions nearby.

Hearing this, the eldest goblin quickly stepped back.

Seeing the goblin brothers enter a safe distance.

Li Meng then took out the fire crystal and inserted it into the groove of the high-end rune magic circle.

Then he adjusted the angle and aimed the magic cannon at a mountain several kilometers to the north.

The magic cannon can tilt upwards to 40 degrees.

A dedicated gun mount will be designed when deployed on an airship.

The up and down tilt will only be higher.

The problem of shells falling out of the barrel at a downward angle is also easy to solve.

The shell does not touch the bottom of the barrel.

A space will be left at the bottom of the barrel to expose the fireball to explode.

Therefore, during the design, the diameter of the bottom of the barrel is slightly smaller than the gun body.

When the shell enters the chamber, it will get stuck in the barrel due to its own weight.

Therefore, it will not fall out even at a low angle.

Finally, Li Meng took out a small hammer and smashed it at the fire crystal stone.

There was a "bang" sound, and the fire crystal flashed.

As the magic power leaked out, the magic energy absorbing rune magic circle lit up.

"Oh!"

The next moment, the magic cannon fired violently.

The deafening sound of artillery fire echoed throughout the world.

A dazzling tongue of fire burst out of the muzzle.

A wisp of white smoke passed by over the forest.

A few seconds later, a fire suddenly flashed on a mountain five kilometers away.

A huge mushroom cloud of fire slowly rose from the cliff halfway up the mountain.

The flames and shock waves from the explosion tore apart a large area of ​​the mountain.
