"Blackbeard, more than 30 confidants, gathered more than 500 people, burned, killed and robbed everywhere."

Among these words, the first one is the one who makes Luo Sen feel the most headache.

Blackbeard, former officer of the Palasen Empire, and leader of the defeated soldiers, was his identity on the surface, but in the secret, he had an even more terrifying identity, that is, he was actually a high-level werewolf.

Werewolf, half human and half wolf, is close to 3 meters tall, has strong muscles, hard bones, and can easily weigh more than 400 kilograms. It is as strong as an elephant, and has terrible vitality.

An ordinary werewolf, swinging a claw at will, can slapped a domestic buffalo of four or five hundred kilograms and flew five or six meters away. The sharp claws can easily break ordinary swords. The skin is extremely tough. Ordinary swords can only draw a shallow bloody mouth at most, and they can completely heal in less than ten minutes.

Higher werewolfs are even more terrifying. Their power and size are larger than ordinary werewolfs, and they can freely change between human form and wolf form. It is not bad when they are human form. Except for their greater strength, they don’t look much different from ordinary people, but when they are weeping, they siege the city with flesh and blood!

In the game, since the appearance of Blackbeard, Sunderland and its surrounding areas have become terrible. At the beginning, Blackbeard led his bandits to sweep away the surrounding villages of Sunderland. After almost all the villages were destroyed, he also gathered more than 1,000 people. Then, he led the more than 1,000 outlaws to attack Sunderland. After a few days of the battle, Blackbeard appeared in a werewolf form, captured Sunderland, killed the lord Baron Draco, and replaced him, becoming the black lord of Sunderland, and began his terrifying reign.

In the game, as a hunting master, Rosen once sneaked into the fallen town of Sunderland and killed Blackbeard. Fortunately, Rosen succeeded in one go, and his main weapon at that time was the Spiral Troll.

‘Hey~ I’ve been so busy lately that I’ve forgotten that I’ve had this incident. It’s also a big deal that Sunderland is just a little bit of a big place, it’s really inconspicuous.’

‘It seems that my weapon building plan has been accelerated.’

Thinking in a mess, Rosen turned around and walked towards Savi's glass shop.

In times of troubled times, everyone only wants to survive, luxury goods are the least valuable. Now that the defeated soldiers outside Sunderland Town are raging, every family is trying their best to store grain, where is there anybody who has the heart to fiddle with glass?

When Rosen arrived at the glass shop, there was no one in the shop except Savi.

Fatty Savi sat behind the counter with a sad face, his big and fat white and round face almost wrinkled into a bun.

"Savi, where are you guys?" Rosen asked.

"I can't afford to support it, I'll quit." Savi was listless.

Seeing him like this, Rosen shook the parchment in his hand: "I brought new craftsmanship. Do you still have to learn it? Let me agree first, if you don't learn it, you will breach the contract first, and I will not refund the money."

Savi smiled bitterly: "I want to learn, but nowadays, who has the spare money to buy glass?"

"The war will always pass."

"Who knows if I can hold on until then, Blackbeard is coming in a fierce manner. I don't even think Sunderland Town is safe."

Rosen put the parchment roll on the counter and advised: "I tell you that the mirror grinding technique is different from ordinary glass accessories."

Savi held his 30% fat chin with his hands and looked at Rosen weakly: "Why are there different methods? Are they all luxury goods? Who is the ordinary person buying this thing these days?"

Luo Sen said, "You think, glass jewelry is nothing more than just a good look. It doesn't matter if there is one, right?"

"Yeah~~~" Savi nodded sadly.

"But the magic mirror is different. In addition to looking at women, the magic mirror can also give scouts and sentries to detect the enemy's situation. With the magic mirror, if the enemy wants to attack, we can see it from afar. Wouldn't this take the lead?"

"Huh?" Savi was excited and sat upright: "Master, what you said makes sense."

The fat man's head began to turn, and after a few turns, his back drooped again: "No, no, even if I can really make a magic mirror, this thing must be very costly. Which lord is willing to use this thing for the foolish soldiers?"

Luo Sen reached out and knocked on the counter, cursing: "You are stupid, the cost is high, won't you think of ways to reduce the cost?"

Savi looked confused: "How to subdue the law?"

Rosen pushed the roll in the direction of Savi: "Take it and take a closer look and you'll know."

Savi spread out the parchment roll half-believingly. Looking at the first one, he saw four words on the title: 'Geometric Optics.'

He moved slightly in his heart, then looked down, and saw the sentence "Light can be abstracted into countless straight lines". Next to this sentence, there was also an intuitive picture.

Seeing this sentence, Savi suddenly shook his heart and stretched out his hand and slapped his head: "Yes, why didn't I expect it?"

He suddenly became very interested and devoted himself to it. After looking at a few lines, he saw another sentence: "Why do chopsticks inserted in the water seem to be broken from the side? Why do you shoot a fish with an arrow, and you can't shoot directly at the shadow of the fish, but at the shadow of the fish? The reason is because of the refraction of light."

Savi has a rich life experience. As soon as he saw these two sentences and then saw the accompanying pictures next to him, he immediately understood. He couldn't help but slap his thighs and shouted: "Exquisite!"

At this level, he was already introduced into the Optical Hall by Rosen.

Rosen was not idle either, so he closed the door of the glass shop, and then led the lost Savi toward the backyard studio.

When he arrived at the studio, Rosen said to Savi, "Stay on, I'll borrow your stove."

Savi didn't raise his head, his eyes stuck to the roll: "Master, you can use it."

Rosen was not in a hurry to raise the fire, and he said to Savi: "Do you have oil?"

"What oil?"

"Any oil is OK." Rosen returned, and he used the oil to quench it.

"I have olive oil in my kitchen, so I'll get it." Savi's eyes were still staring at the parchment, and his body turned around, and his head slammed into the door frame.

Seeing his obsessive appearance, Rosen no longer disturbed: "Look carefully, I can do it myself."

"Well~ OK, OK, tsk, it's amazing~" Savi's soul had fallen on the parchment.

Rosen stopped disturbing him. He went to the kitchen to take a look and took half a bucket of olive oil. After looking, he found that there were a lot of impurities in the olive oil. He activated the alchemy power to quickly settle the impurities in it to the bottom of the oil barrel.

After he finished, he put on cowhide insulation gloves, picked up a wooden shovel and added charcoal to the stove, ignite the fire, pulled the bellows, and quickly raised the fire.

After the charcoal was burning, Rosen took the iron pliers and clamped the iron pipes cut off yesterday and placed them on the charcoal fire.

This iron pipe is cast and is the worst-quality gray cast iron. What Luosen has to do is to process this thing into a combined gun barrel.

Metal processing is his old career. When he was internship from college, he went to a steel processing factory. After being admitted to graduate school, he was most interested in metal materials. In addition to studying, he searched for information and conducted experiments, and spent almost all his free time on it.

'On Earth, military gun barrels are made of high-strength chromium-molybdenum alloy steel. But chromium and molybdenum are rare metals, which I can't do now. The barrel of my spiral trolley does not require rifle and does not require high barrel strength requirements. As long as the process is proper, ordinary high-strength steel is enough to be competent.'

‘I want the barrel now. The barrel needs the performance of the barrel to be resistant to high temperatures, hard, and at the same time it requires a certain degree of toughness. If it is too brittle, continuous shooting may cause the metal to create cracks and explode. To achieve such performance, I have to arrange the metal structure well.’

While the iron pipe was still heating, Rosen took out the parchment paper and a quill pen and started to calculate.

For a moment, the fat white Savi was addicted to geometric optics and mirror grinding techniques and could not extricate himself. Rosen focused on designing the steel he wanted. Neither of them spoke, and the studio was quiet.

After a few minutes, Rosen came to the result. He looked up at the iron pipe, which was already burned red by the charcoal fire.

“It’s time to start.”

Luo Sen thought about the specific process again, then activated the alchemy power and gathered oxygen slightly towards the air outlet of the bellows. At the same time, he slowly pulled the bellows.

‘Hu~Hu~’

The charcoal in the stove received more oxygen supply, and the temperature began to rise slowly. After a while, the melting point of the iron was reached. The iron pipe began to soften and deform, and was about to melt into molten iron.

‘It’s now.’

Rosen maintained the furnace temperature unchanged, the alchemy power lingered up, and the tentacles of thinking felt the structure inside the metal tube with all their strength.

He removed the internal cavity of the metal, precipitated excess carbon elements, and rearranged iron atoms.

It is worth mentioning that when doing this series of actions, Rosen did not forcibly fight against the metal bonds in the iron. He borrowed the thermal motion of atoms at high temperatures and took advantage of the situation to achieve the results he wanted bit by bit.

This method has both advantages and disadvantages. The advantage is to save labor, and the disadvantage is to be extremely low efficiency.

I don't know how long it took, but Savi was still immersed in the new optical field, while Rosen breathed a sigh of relief and slowly lowered the furnace temperature. After the iron pipe dropped below the melting point, he clamped the iron pipe with iron pliers and began to perform the final heat treatment.

Metal heat treatment is nothing more than annealing, normalizing, tempering and quenching. What is the final performance of metals? The quality of heat treatment is very important. For the same materials, due to different heat treatment, the final performance is very different.

After all, Rosen is not a professional worker. Although he has theories, his practical methods are very unfamiliar, but it doesn't matter. He has the power of alchemy and can sense the internal structure of metal at all times. Once the situation is wrong, he can adjust it at any time.

Just tried and made mistakes bit by bit. About an hour later, a hollow iron pipe with an inner diameter of about 2 cm appeared.

This iron tube is dark and has a smooth surface and a cool touch. The inner holes are very round and the lines are so precise that it is difficult to describe. If you flick it gently with your fingers, the sound makes is dull and crisp. Just by this appearance, it is enough to make people feel its extraordinaryness.

Luo Sen was happy: 'The most critical part is the barrel and the other is the bullet. Now that the barrel is available, other parts can be easily completed. As for firing bullets, this is not difficult. The spiral trolley has been completed by 70%.

He was also exhausted. After carefully putting the barrel of the gun, he sat next to the fire to rest and rest. After sitting for a while, after feeling that his energy was recovering slightly, Rosen took out the parchment paper and began to record the entire operation process.

This step is not necessary, but a habit that Rosen developed on Earth. As long as it is a successful experiment and without recording it in words, he always feels that something is missing and he is completely uncomfortable.
