In the Baron's Palace, Savi worked with several craftsmen assigned by the Baron, and soon set up Lawson's new studio.

"Master, what now?" Savi asked respectfully.

"Did you complete the calculation I gave you?" Rosen asked.

Savi suddenly had a toothache on his face, and the fat on his cheeks twitched again and again: "Big ..... Master, it's still ...... Almost, soon to be fine. ”

He couldn't say anything, which shows how difficult Rosen's task was for him.

Lawson waved his hand: "Hmm~ Then you can continue to count." ”

With a bitter face, Savi took the parchment and quill, and hid in the corner of the studio to work hard.

It's not that he doesn't want to work hard, it's just that this problem is too difficult, and there are too many new knowledge involved, which greatly exceeds the limit of his ability, but what Rosen said is right, these days, he has carefully studied the craft of composite lenses, although he has not finally solved it, but his understanding of geometric optics has been much deeper.

Because of these benefits, Savi sighed, but still did his best to calculate.

Lawson ignored the white fat man who was frowning bitterly, turned to Anne and said, "Come, show me your hand crossbow." ”

Anne handed over the crossbow.

Rosen took it in his hand and tried to pull the string, feeling the force, only to feel a little effort: "Annie, this crossbow is too light for you."

Right? ”

Anne nodded: "Yes, I can barely feel the force, I can wind it with a hook of my fingers." The speed is fast, but the shooting power is also weak. ”

Lawson carefully looked at the materials used in the crossbow, the main body of the crossbow is made of hardwood, and the crossbow arm responsible for accumulating energy is made of ordinary oak, the oak surface is smooth and shiny, and it is obvious that it has undergone some special anti-moth and mildew treatments, and the bowstring of the crossbow is made of cow tendon, and the cow tendon is specially smeared with a layer of yellow wax for maintenance.

Overall, this is the most common hand crossbow, which can cause lethal damage to ordinary people within 15 steps, and if it is supplemented by special arrows, it can also cause damage to some monsters if it is used to shoot vital points.

But if the monster has thick skin and a surprising reaction speed, then this crossbow is basically an ornament.

After reading it over and over again, Rosen took out a parchment roll, a quill, and ink, and lay on the workbench next to him to write and draw, and after more than 10 minutes, he suddenly said: "Annie, the strength of your crossbow is too weak, I am going to use steel as the main material to rebuild a new crossbow to improve the lethality." ”

Anne glanced at the parchment in front of Rosen, and saw that there were many crossbow parts drawn on it, and there were many strange words listed next to it, she tried to look at it for a while, but she felt dizzy, and could only withdraw her gaze, and asked, "Steel crossbow, how strong is it?" ”

"It can reach more than 10 times that of this hand crossbow, and it can shoot up to 200 meters. Of course, it will be more difficult to wind, and the force will probably exceed that of this crossbow by 10 times. ”

Anne's eyes lit up: "10 times!" 200 meters? Of course. ”

"Then I'll go to the baron and ask for some iron."

So saying, he walked out of the studio, and walked around the courtyard of the Baron's Palace, and when he found no Baron, he inquired with the guards, and learned that the Baron was currently personally directing the reinforcement of the wooden walls at the eastern entrance to the town.

He was about to go out to find the baron, and as soon as he reached the door, he saw a butler, Matt, approaching him.

Matt had just received the benefits of Rosen's more than a dozen runtes, and he had a very good impression of Rosen, and took the initiative to say hello: "Mr. Rosen, you seem to have something?" ”

Lawson nodded, and did not hide his purpose: "My friend Anne also wants to participate in the defense of the town, you know, she is a very powerful stalker, if you can get a powerful weapon, she can even fight the werewolf single-handedly." So, I want to get some iron from my uncle so that I can get her a new crossbow. ”

Matt agreed, "It's a very good idea, and while many people are prejudiced against mutant stalkers, they are very strong warriors. However, the baron is very busy now, so I don't need to trouble him for such a trivial matter, and I can solve it for you. ”

"Oh, really? That's very much appreciated. ”

Matt smiled and asked, "How much iron do you need?" ”

Rosen estimated: "About 15 pounds." ”

"It's only 15 pounds, you come with me." Matt waved his hand to Lawson and walked towards the arsenal in the courtyard.

Lawson immediately followed.

Matt reached the door of the arsenal, but instead of entering, he walked towards a room next door, and when he opened the door, he was greeted by a strong smell of damp mildew and rust.

"It's all broken swords that were damaged during the soldier's training, and they haven't had time to be repaired by the blacksmith. Although the surface is very rusty, it is made of good iron. If you can use it, just take some of it. ”

Rosen looked into the small house, and saw at least 20 broken swords lying haphazardly against the wall, all of which were old on the surface, but from the rusty places, it could be seen that the iron was indeed quite good.

He was very satisfied, walked into the room, hugged the three broken swords, weighed them, and said, "These are almost enough." ”

Although it was a broken sword, he didn't take it in vain, he dug it into his pocket with one hand, and took out more than 30 Runte and stuffed it towards Matt.

Matt subconsciously refused: "Hey~ What are you doing here?" These iron don't cost money. ”

Rosen smiled: "Uncle Matt, how can there be iron that doesn't need money." In the town, a pound of iron costs at least 4 runtes, and here are more than 10 catties of good iron, and I only give 30 runtes, which is already a little. ”

Matt hesitated, then put the money away, and his attitude became better and better: "Okay, if you still want to use iron in the future, you can come here and get it directly." You have cured your master's illness, and no one will embarrass you for such a little iron. ”

Rosen was stunned: "I just treated my uncle, why was it cured?" ”

Matt laughed, "You don't know. In just a moment, the color of the red dots on the master's arm has turned light brown, and the master is overjoyed, and has been praising your medicine as a miracle medicine. ”

Rosen was also very happy, and nodded again and again: "Oh~ That's good, that's good." ”

After a few more conversations, Rosen said goodbye to Matt and walked towards the studio with the broken sword in his arms.

When he arrived at the studio, Rosen asked Annie, "Will you use a blacksmith furnace?" ”

"Of course. I studied specifically in Holderburg. ”

"That's good. You give me an assistant, and we'll start building crossbows now. ”

"No problem." Anne agreed.

Rosen immediately began to arrange specific actions: "Then next, you burn these irons red. I'll calculate the specific parts I need. ”

Next, the two of them went their separate ways.

The structure of the crossbow was not complicated, and there was a ready-made hand crossbow as a reference, so Rosen quickly drew the specific dimensions of the parts, and then he began to design the mechanical properties of the steel required for the parts.

On the other hand, Anne also began to light the fire, at first, she was not very skilled, but soon, she got the hang of it, and soon the fire was very strong. Several broken swords on the crucible were burned red and almost melted.

"Lawson, almost."

"Hmm~ I'm almost ready here."

After completing the last few tasks, Rosen checked back and forth, and when he was sure that everything was correct, he walked over to the stove and poured oxygen into it.

'Boom~' The fire instantly turned pure white, and the color of the broken sword turned white immediately after, and then it began to melt into molten iron like a candle.

Although it was not the first time to see such a terrifying white flame, there was still a deep awe in Annie's heart, and not far away, Savi was also attracted to attention, he shrank his body and muttered in a low voice, "Lord Activated Flame is here again." ”

。。。。。。。。。。。。

Here, Rosen was busy building a new crossbow for Anne, and at the east gate of Sunderland, the Baron was standing on a watchtower behind a wooden wall, holding the new magic mirror that Rosen had repaired for him, constantly watching the situation outside the town.

Observing the enemy with a magic mirror is the result of the baron's whim.

'Yes, very good, you can see it from miles away. Hmm~ Rosen's little guy's craftsmanship is really reliable. It's a pity that this thing is too expensive, otherwise I'll give each guard a magic mirror, and I'll see who can sneak up on me! ’

For the magic mirror, the baron loves and regrets.

At the same time, more than a dozen miles away, outside the village of Caopo, Dias, who had just escaped from Sunderland, was unfortunately captured by the robbers. He was stripped naked, locked in a wagon, and transported to the mountains and forests outside Caopo Village.
