I picked up the dragon girl at the beginning and I used artillery fire to liberate the other world

Early in the morning, Bai Yan came to the blacksmith shed in the wild. However, the original small shed had become a small house made of stones, and there were soldiers guarding it. The blacksmiths had never left here.

All this was because winter was coming. After Bai Yan said that the iron barrel-shaped thing they made could resist the monsters in the dark forest, they decided to stay here first.

Every year, the monsters from the Dark Forest would enter the Black Iron Castle, wreak havoc, and then flee. As for the people of the territory, most of them hid in the bunkers of their homes until the cold winter faded away.

But at the same time, there will be a small number of unlucky people who will die in the mouths of monsters.

Not far away, the soldiers were building some simple houses, which would be used as sleeping places in the future.

"Thank you for your hard work, everyone."

Bai Yan walked into the house, and immediately a wave of warm air made him feel much more comfortable. It was not even eight o'clock, and the blacksmiths had already started working.

Seeing Bai Yan coming, everyone stopped hammering, and there were already more than a dozen cannon barrels of different sizes standing nearby.

These gun barrels were forged by them while working overtime in the past two days. They also added the rifling that Bai Yan mentioned, and recorded in detail all the detailed steps in the forging process of each gun barrel.

"Your Highness, these are samples." Uncle Luke, the most experienced blacksmith, enthusiastically introduced his works to Bai Yan.

Bai Yan looked at these cannon barrels and found that they were indeed much stronger than the black lump before. However, after the defense system was complete, it was necessary to speed up industrialization.

"Thank you for your hard work. Let's take a break today. I will take this batch of gun barrels for testing first. Once the results come out, I will trouble you to mass-produce the gun barrels.

As for the speed, just take it slow.”

Bai Yan said this, and then pulled his precious cannon to Wald's "territory".

And this great chemist did not disappoint his expectations. Looking at the deep pits in front of him, which were getting bigger and bigger, Bai Yan nodded with satisfaction.

Although current artillery shells can only use solid bullets, gunpowder with more violent explosions can also make these solid bullets fly farther.

"Walder, I'm here to bring you equipment."

"Your Highness! You have no idea how powerful this fire magic is!" As soon as they met, Wald walked towards Bai Yan excitedly.

"I should have thought of it earlier. If we put this thing into an iron ball, the iron pieces that break when it explodes can penetrate a group of people around us!"

As Wald spoke, he pulled Bai Yan towards the experimental factory. From a distance, they could see several large pits, but when Bai Yan walked closer, he discovered that the originally flat land had become charred black. It was hard to imagine what kind of inhuman destruction this virgin land had suffered.

"Look, Your Highness. This is my latest creation."

Looking at the ball in Wald's hand, Bai Yan touched his chin and exclaimed in amazement. Isn't this just a fragmentation bomb? However, the fact that he could think of this shows that this old man is quite smart.

"This thing is great, but how do you detonate it? Or how do you control the timing of its explosion?"

"Your Highness, I haven't thought this through yet, but I'll find a way later."

"That's right, but now, let's think about how to make the cannon fire further."

Although Bai Yan's Book of Everything has told him the method, with the current industrial level, it is impossible to produce a real artillery shell.

After a whole morning of various tests, the best barrel was finally selected, with a caliber of 260 mm and a range of up to 1500 meters.

It is difficult to see a person's figure at this distance even with the naked eye. There is no doubt that this is a terrifying shooting range.

"Your Highness, you are indeed the incarnation of God." Wald almost knelt down to Bai Yan again. He couldn't imagine how useful this thing could be in defending against foreign enemies, or in other words, it was born for war.

"Really? Then I'll give you another good thing." Bai Yan laughed and took out the cement making method that he had copied from the Book of Everything last night from his arms.

"Take a look, Walder. I think this might interest you more."

"Your Highness, what is this?" Walder took the parchment from Bai Yan. This was such a familiar scene! The only difference was that the last time he was handed the paper was by the armored Grey Knight.

He suppressed his inner excitement and looked at the contents of the paper carefully. At the same time, he began to breathe heavily and his eyes showed an expression of incredible surprise.

"This, this is simply rock magic. Oh my God! Your Highness, you have once again stripped the most primitive rock magic from the earth!"

After seeing the effect of cement, Walder immediately understood the importance of this material. With it, Black Iron Castle would have an indestructible and magnificent wall in a short time!

"I leave it to you. Complete it within three days." Bai Yan patted Wald's shoulder. Wald was his most loyal believer so far. His favorability towards him had reached an astonishing 9999!

This is also the reason why Bai Yan told him all the methods of making gunpowder and cement. The Book of Everything can not only allow him to understand the basic information of the people he touches, but also show the so-called favorability, which seems to be something that only exists in games.

"Everything will be as you wish, Your Highness." Wald bowed to Bai Yan, then hurried into his simple laboratory.

After doing all this, Bai Yan handed over the barrel of the first-generation cannon to the blacksmith area and then returned to the lord's castle.

He had just sat down on his wool blanket to warm himself when Edward walked in with his fat belly.

"My Lord, it took me a while to find you." He looked a little anxious, and the wrinkles on his face disappeared a few times after he saw Bai Yan.

"What's the matter?" Bai Yan rubbed his head and asked impatiently.

"What are you thinking? How can you give your land to those untouchables? They will make the best fields go to waste.

As for taxes, they are set too low. If this continues, our fiscal revenue will be reduced by two-thirds.

And why don't you even want the serfs? Who will work for us in the future?"

Edward had long wanted to question the Third Prince, whose temperament had changed drastically, about these things, but he had always been a little timid and only made up his mind today.

Because he heard from Grey that His Highness wanted to expand the army. Oh my God, how much silver and gold would it take!
