With that, the goblin king led the group to a heavily guarded cave.

At this time, the cave was full of busy goblins.

And when Wang Zhen saw what they were busy with, he was immediately surprised.

Because in front of him were steel-making blast furnaces and goblin craftsmen casting things from molten iron.

Moreover, he clearly saw that the things that the goblins used to heat were coal.

I didn't expect the goblin clan to master the basic things of industry so early.

Seeing this, Wang Zhen couldn't help but think.

"Hehe, look, this is the iron-making equipment invented by our goblins. ”

"We call it an iron-making furnace, and the weapons forged from the molten iron it is not only extremely hard, but also not badly flexible. ”

As he walked, the goblin king pointed to the blast furnaces.

When everyone heard this, they understood what the round things were.

After leading everyone through the blast furnace, the goblin king led everyone to the casting area again.

Here, the king and the others saw the goblins pouring molten iron from the blast furnace into the prepared grinding tools.

After a while, round iron cylinders with a length of two meters and a diameter of about twenty centimeters were made by the group of goblins.

Then other goblins stepped forward and carried the iron cylinder away.

"Hehe, that's part of the crafting process for the weapons you're going to see. ”

As he continued to walk with the crowd, the goblin king said proudly.

So saying, the goblin king led the people to another cave.

In this cave, there are also a lot of busy goblins, and the goblin king took everyone to take a look, only to see what they were assembling!

When they finished assembling it, Wang Zhen was immediately startled when he saw it.

Because the thing that the goblins successfully assembled turned out to be the kind of old-fashioned artillery used in ancient wars on the earth.

"Hey, look, that's the kind of weapon I'm talking about. ”

"This weapon, once used, is so powerful that it can break through mountains and gravel! I named it Thunder. ”

After seeing that the group of dwarf goblin craftsmen had successfully assembled, the goblin king pointed to the cannon and spoke.

"Hehe, uncle, you can't brag, right, just this thing, can you also open mountains and gravel?"

When the elf little Lori heard this, she asked suspiciously.

In her opinion, this is just an iron cylinder and a large iron wheel, how can it be possible to open the mountain and rubble.

"Haha, don't underestimate it, since you don't believe it a little, then today this king will take you to see its power. ”

As he spoke, the goblin king commanded several goblin craftsmen and pushed the cannon outside.

"Come with me, this thing is very powerful, and it is easy to cause casualties in underground experiments, so let's go outside. ”

As he spoke, the goblin king led everyone to follow the craftsman who was pushing the thunderbolt and walked outside together.

Once on the surface, the goblins got busy.

I saw one of the craftsmen take out a black thing that looked like pot ash from an iron bucket and pour it into an iron hole behind the thunder.

Seeing this, Wang Zhen suddenly thought of something, and that was gunpowder.

If this thing is really a cannon, then what the craftsman poured into the barrel is definitely gunpowder.

Although the guess came out, Wang Zhen did not make a sound, but watched with interest.

He was born at a time when traditional artillery like this was long since retired!

Therefore, he has really never seen how powerful the crystallization of the wisdom of the ancient people is.

After the goblin craftsman poured the black gunpowder into the thunder, another craftsman took out a round iron ball about ten centimeters in size from the iron bucket on one side.

Then, the craftsman stuffed the round iron ball into the barrel of the thunderous cannon.

After it was done, he didn't know that he took out an iron rod from there and pressed it down the barrel to compact the iron ball.

Another craftsman took out a fuse made of dried leaves and stuck it in the place behind the barrel where the powder was fired.

"Alright, Your Majesty, the Thunderbolt is ready to be launched. ”

When he was done, one of them, the goblins who looked like the leader of the craftsmen, came to the goblin king excitedly and said.

"Well, aim the Thunderbolt at the gravel pile over there, and show your allies the great invention of our goblin clan. ”

When the goblin king heard that he was ready, he continued to speak.

When the leader of the goblin craftsmen heard this, he hurriedly commanded the rest of the goblin craftsmen and began to adjust the direction of the cannon barrel of the thunderous thunder.

After it was adjusted, the goblin king gave an order, and the goblin craftsman took a torch from the other goblin and lit the fuse of the cannon.

"Zizizi......

The sound of the fuse burning is clearly visible, and when it is burned, only the loud sound of the boom is heard.

The barrel of the cannon shook, and at the same time as a flame came out, the iron ball in the barrel also flew towards the gravel forest in the distance with a thunderous momentum.

"Boom"

After a loud bang!

The gravel forest kicked up a large cloud of dust.

"Hehe, allies, let's go see how the power goes?"

Seeing this, the goblin king smiled proudly and led everyone towards the gravel forest.

When they came to the gravel forest, they were greeted by a fragmented stone block and a black iron ball.

Its attack range is at least about two meters.

If it were a human being, there would be at least a dozen casualties in this shot!

"Hee-hee, uncle, uncle, this weapon is so powerful, what's its name?"

Seeing the power caused by the artillery, the elf little Lori asked with wide eyes in interest.

She didn't expect that the inconspicuous iron cylinder could shoot such a heavy iron ball a hundred meters away, and it was still so powerful.

"Hehe, I call it thunder, how awesome is it?"

When the goblin king heard this, he asked proudly.

Seeing the light of the elf little Lori's worship, the goblin king was particularly proud at this time.

"Anyway, in general!"

At this time, Wang Zhen suddenly spoke!

Seeing the power of the artillery, Wang Zhen finally understood why this old-fashioned artillery was gradually becoming obsolete.

First of all, there is the problem of distance, just now he took a look and found that the attack distance of this artillery is about 200 meters.

This distance is not as good as the attack distance of some archers.

When the time comes, it is estimated that after a few rounds of bows and arrows, the craftsman who operates the artillery will die cleanly!
