I don't know why, in the last two days, there has been a lot less news of bandits, and there are not as many refugees as in Sunderland as in the past few days.

It was as if all of Blackbeard and his robber men had vanished from the world overnight.

"I'm afraid it's the last calm before the storm." Anne said lightly, her eyes were also faint, as if she had seen through everything.

Rosen smiled: "That's right." But calm is always calm, take this opportunity to rest. ”

Although he said that he was resting, Rosen had not rested, and he was fiddling with a device nearly a man tall in the corridor on the stone wall of the Baron's Palace.

This thing works similarly to a trebuchet, which is to throw heavy objects. It was for this reason that the Baron, who was fascinated by the trebuchet, would agree with Rosen to erect it on the stone wall.

The main body of the instrument resembles a peculiar large metal spoon, the spoon of the 'soup spoon' is round and deep, which can well accommodate an iron ball about 20 cm in diameter, and there is a movable iron buckle behind the 'spoon', and a thick arm hemp rope is tied to the clasp.

The 'soup spoon' has a long flat iron handle, about 1.3 meters long and 3 cm thick, and below the 'soup spoon' is a fixed iron base, and on both sides are some wooden shelves wrapped in iron sheets, which stabilize the ejection process of the 'soup spoon'.

After fiddling with it for a while, Rosen said to Anne, "Come, do me a favor and pull this spoon off." ”

Anne stepped forward, grabbed the hemp rope, and pulled down hard, and the handle of the 'spoon' was bent down, and the fixed wooden frame at both ends of the spoon made a 'creaking' sound, which showed that the metal handle contained a huge elastic force.

The soup spoon originally maintained a 90-degree angle with the ground, and when the spoon handle was bent to a 45-degree angle by Annie, there was a huge elasticity from the spoon handle, and Anne couldn't bear it, she was all over, and her hands pulled the hemp rope hard, and her white jade-like cheeks were red: "Okay, no, I'm about to lose it." ”

"Yes, hold it for a while."

Lawson walked over to the iron frame and slightly moved a strangely shaped long-handled iron buckle on the wooden frame, which was stuck on the clasp under the 'soup spoon', and buckled the soup spoon.

"Okay, let's let go, and take the rope away by the way."

"Whew~" Anne breathed a sigh of relief and took away the hemp rope.

Lawson picked up a hollow stone ball of about 20 centimeters and put it in the spoon of the 'soup spoon', and then quickly squatted down, grabbed a wooden handle under the machine with both hands, and rotated it vigorously.

As he moved, the front side of the simple mechanical base began to rise slowly, and soon the base of the machine was at an angle of about 15 degrees to the ground.

After doing so, Lawson immediately stepped aside, pinched one end of the buckle with both hands, and broke it hard.

'Collapse~', and the whole instrument shook.

The metal 'soup spoon' quickly rebounded back into place, and the stone ball placed in the soup spoon flew out quickly 'whew~'.

The stone ball flew over the town square outside the Baron's Palace, over the slopes of the entire town of Sunderland, and finally smashed into the middle of the river outside the town of Sunderland, and with a 'poof' sound, a large splash of water.

"Fly far." Anne was subconsciously speechless. Although this stone ball was hollow, she had weighed it with her hands before, and it had to weigh 20 pounds, and throwing the 20-pound thing out was 300 meters away, which greatly exceeded the limit of her strength.

Rosen smiled: "Actually, it can go further, but at this level, it is enough to do a test." ”

He took out parchment, a quill, a precision scale, and a metal disc, and calculated while making gestures, and muttered: "When the firing angle is 15 degrees, the firing distance is 537 meters...... Parabola....... Modulus of elasticity of spring steel...... Material yield limit ......."

Anne listened to it for a while, and then she couldn't listen anymore, not that she didn't want to hear it, she was also interested in this trebuchet-like machine, but she really couldn't understand it.

There are many things Zhang Yuan said, and she can't even figure out what a single word means.

After waiting for a while, she saw that Zhang Yuan was still gesturing, and finally couldn't stand it anymore, so she walked down the stone wall and walked towards the studio.

After many days of contact, Savi, the glassmaker, became acquainted with her, and occasionally spoke to her. Compared with Rosen, Savi is still an ordinary person, at least what he says, Anne can basically understand.

In the studio, Savi is also very busy.

He was burning the glass, while pushing the bellows hard, from time to time to look at the melting of the materials in the crucible, after hearing the footsteps behind him, he glanced back, and when he saw that it was Anne, his fat face showed joy: "Quick, do me a favor, add the purple clay over there to the crucible, yes, yes, that's it." Don't add more, but add what I have weighed, and spread it evenly. ”

Anne complied.

After adding the purple soil, Savi immediately said again: "Quick, help me stir it." ”

Anne was speechless, she felt that she was once again free labor, and although she was reluctant, she continued to help for the sake of Savi's busy sweat.

After stirring for a few minutes, Savi looked at the crucible, and his eyes showed a deep joy: "It's done!" It's done! The glass is finally not green. There are also a lot fewer bubbles, haha~ The method said by the master really works! ”

He danced with joy, and then he carefully poured the glass onto a clay mold.

When Anne looked at it, she saw that the glass on the mold was a very pale yellow, with a trace of air bubbles in it. Just looking at the texture of the glass, it is indeed a lot better than Savi's previous works.

"Hmm~ It's pretty good." Anne nodded in agreement.

Savi was so excited that his lips trembled slightly: "It's more than that. Let me tell you, this glass can also be used to polish the lenses of the magic mirror. You see that big iron ball doesn't have it, that's the tool for sharpening the lenses. Oh, the master's wisdom is endless, I have never thought of using this method before! ”

When Anne looked up, she saw a half-human-high wooden platform in the middle of the wooden platform, with an iron ball about 20 centimeters in diameter in the middle and two pedals under the wooden platform.

Of course she'd seen it, because she was right next to it when Lawson made it.

She even knows the use of this thing, as long as a person sits in front of the wooden platform and presses the pedal with both feet, the big iron ball will rotate at high speed, as long as the iron ball is mixed with sand powder mixed with water, and then the glass is close to the surface of the iron ball, it can grind a circular surface on the glass. If you replace a very fine powder, which Lawson calls a 'precipitated abrasive', you can grind a very smooth mirror surface!

"Hmm~ That kid Rosen has a lot of things in his head...... Perhaps, I shouldn't have called him a kid anymore, I have to call him a master. Anne thought to herself.

Ignoring Savi, who was almost insane, Anne walked out of the workshop alone.

There was no one in the courtyard, and the Baron and his men were all on the outer walls of the town, ready to deal with the werewolf attack.

Anne was bored alone, so she took out the fish-scale sword and practiced swordsmanship, and after practicing for a while, she suddenly heard a noise at the door, and when she turned her head to look, she saw that Miss Mary had walked in from outside the gate of the Baron's Palace.

Sister Mary was wearing a brand-new gray cotton robe, with a small wooden box at her waist, and she walked with her head held high, which was completely opposite to the humble appearance of the past.

'Oh~ The Baron must have just taken a shot, poor Baron. Anne gloated.

Mary also saw Anne, who smiled and beckoned to Anne and said with a smile, "Good morning." ”

Anne smiled and nodded in response.

Mary asked, "What about my lord?" ”

Anne pointed to the stone wall of the Baron's Palace, "Look, he's experimenting with his new toys there." ”

Mary turned her head and said, "Hmm~ It seems that the adults are very busy." I'll put my things away and help him. ”

After saying that, she quickened her pace into the wooden building, and after a while, she changed into a neat and simple cotton robe and trotted out, and walked briskly up the stone wall.

Anne followed her gaze and saw Rosen and Mary say hello, and then said a few jobs, and Mary immediately began to get busy.

"Hmm~ Sister Mary is really a good assistant, and she is much more patient than me." Anne thought with relief, and she thought again, "Judging by Rosen's serious appearance, that 'soup spoon' should be of great use." In the Baron's Palace, it seems that I have the strength to pull that thing, so I'll go over and help. ”

So, after taking a circle around the Baron's Palace, Anne returned to Rosen's side.

After shooting the hollow stone ball several times in a row, Anne couldn't help but ask, "Rosen, are you going to throw stones with your gadgets?" ”

Rosen shook his head: "Of course not, it's just an experiment now, I'm determining its firing range." ”

"Oh, and then?"

"Then, I'll give Blackbeard a big surprise."

.....................

The quiet day passed quickly, the sun set in the west, reluctantly sinking into the horizon, and the sky quickly darkened.

Behind the grass by the river south of Sunderland Town, more than 10 black shadows suddenly appeared, and the leader was Blackbeard Cummins.

He glanced at the lights in the town of Sunderland in the distance, and his eyes shone with a dull green glow.

"Guys, follow me."

He plunged into the water one by one, and then dived forward in the river, and behind him, black shadows continued to jump into the river.

Tens of meters wide river, Blackbeard only took less than half a minute to dive to the opposite bank, he was not in a hurry to go ashore, but continued to swim around the river bank, about more than 100 meters, the river bank became a towering stone wall, above the stone wall is the Baron's Palace, and below a stone wall, there is a rock slightly concave.

Blackbeard took a deep breath and dived again, groping his hands on the stone wall.

After a few minutes, he surfaced, and his face was full of joy: "Haha, the rumors are really true!" Come with me, guys, and let's surprise the Baron greatly! ”
