With the arrival of the three witches of the Church, the enchantment of gunpowder became faster, and Charlotte was no longer a necessary person there, and was once again freed from her work.

This time instead of taking over Austin's work directly, Charlotte was once again reduced to a tool man and started working in another place.

A few days ago, the craftsmen completed the transformation of the furnace, and the furnace made can refine the metal that is okay, but it is still a lot short of the strength required by Kalian, and it is still hard to make a new one, so Austin came up with an idea, that is, let Charlotte use her ability to try to increase the temperature of the furnace.

After Charlotte went to try it, the temperature really increased a lot, and after reaching the temperature required by Kalian, Austin was really relieved, after all, in this way, the military can be regarded as the next stage.

Of course, it is used to make artillery, at least the requirements for artillery are still lower than those for muskets, after all, in Austin's impression, it seems that it is the existing artillery and the later gun.

However, even if artillery can be produced, it is estimated that not much artillery will be produced in the remaining time. Besides, this metal is only the first step in making artillery, although Karen tried to make a drawing under Austin's introduction, and also tried to scale down and make some, which can be regarded as feasible, as for whether it is really possible, it still depends on the final product to try.

So, all the manpower was focused on this, and soon, the first artillery came out.

Austin was quite satisfied with this bulky thing, at least it still looked very delicate and powerful. It took a lot of manpower to transport this thing to the test site, put a shell into it, ignited it, boom, there was an explosion hundreds of meters away, although it was far from the designated place a lot, but, this is enough, after a shell was launched, Kalian immediately ran to the front of the gun, touched the muzzle of the gun with her hand, slightly hot, it is estimated that it can only shoot ten rounds in a row, it needs to be cooled.

"Karen, how's it going? Isn't there a problem? Is it ready for mass production?" Austin asked.

Karene nodded and said, "Your Highness, it's okay, as expected. ”

After hearing Karen's words, Austin said with some joy: "The problem of overheating, let's leave it like this, when the time comes, use water to cool down, although the service life of the gun has been damaged, but, in the final analysis, this is something for emergency use." ”

"Your Highness, I thought about the improvement of the cannon, and I think that the key to the improvement of the artillery is not the barrel, but the shell, I want to try to improve the cannonball first, improve the power, and if the accuracy is accurate, you can put it on it. "Karen has a new idea for the improvement of artillery.

Austin listened and nodded a little abruptly, yes, the key to the improvement of the artillery is really on the shell, as long as the barrel can support the power of the shell, it is enough, and the lethality still depends on the shell.

"Well, you're not wrong, I'm wrong, you really should focus on the shells, you do it. Austin agreed.

Karen nodded, and went to the institute to get busy.

Charlotte looked at the mess in the distance, then looked at the cannon in front of her, and then looked at Austin, she was really convinced, although this was made by Karen single-handedly, but Charlotte didn't know that if Austin didn't say what she thought, how could Karine do such a thing.

There is nothing wrong with an idea, after all, there is no shortage of geniuses in this world, and they will always have flashes of ideas to change the world. However, it is clear that what flashed through the mind of His Highness Austin was not an idea, but a mature series, as if His Highness had seen such a thing, but did not know it very well.

Austin saw that Charlotte looked at him with some confusion in his eyes, and asked, "What's wrong?"

"Your Highness, you are really powerful. Charlotte said.

Austin smiled and didn't say anything, after all, this is really not his own power, if he wants to say it, it is still Kalian's power, and the mess he said was really done.

"With this thing, I can finally breathe a sigh of relief, even if we can't keep it this time, but as long as this thing spreads, we can one day regain the lost territory. Austin said.

"Well, when I heard the story of the beast tide, I thought it was a legend, and when I really had to fight it, I felt hopeless, but now I feel that I can really fight it. Charlotte said with a smile. Although after knowing about the beast tide, His Royal Highness Austin was busy trying to fight the beast tide with the power of a small town and a town, and everyone was united to follow His Highness, but if they could resist this matter, everyone did not have hope, and no one escaped from the chaos, mainly because the underground shelter was repaired.

However, at this moment, Charlotte is thinking of hundreds of such cannons firing together, an indestructible scene, just thinking about it, her body can't help but tremble, it's really cool!

Seeing Charlotte's face flush with some excitement, Austin knew what she was thinking, smiled, and didn't say anything more.

Karlian returned to the lab and began to work on the refinement of the shells.

Seeing that Karen was busy again, those who were here with Karen couldn't help but let out a wailing sound. This is really terrible, the improvement of gunpowder before, this is so desperate, the main thing is that I haven't had time to get it out, and the personnel in the laboratory have almost collapsed, but fortunately, after His Royal Highness heard about it, he stopped this matter and arranged the artillery thing, which is still a little more idle, and the main problem is the matter of materials, but now, it can be seen that his group is going to be the same as Kalian, and they need to work hard.

"Karen, why did you come back so quickly, the artillery has just been completed, what task has Your Highness given us?" an old man walked over and asked when he saw Karen's appearance.

As the supreme leader of the research institute, if Karen wants to talk about research ability, knowledge or something, no one is unconvinced, and when His Highness says something to everyone, many people have not yet understood, Karen already has an idea.

But when it comes to leadership, there's nothing to say, you see, Your Highness has arranged something, why don't you tell everyone, you went into the laboratory and started to get it, and we people still don't know anything?

"I have a new idea for the improvement of the cannonball, I want to write it down first, and when the time comes, I will discuss with you whether it is feasible, so let's go and rest first, leave me alone. Karen, seeing everyone looking at her, spoke.
