The Last Alchemist

With enough iron, Rosen felt at ease.

He filled the glass furnace with charcoal, and placed a heat-resistant clay crucible in the middle of the furnace, then began to pull the bellows to inject oxygen into the furnace.

"Boom~" The charcoal fire turned white again.

Rosen immediately picked up the tongs and placed the broken plow on the incandescent flame. The broken plow was quickly melted into molten iron and dripped onto the clay crucible.

When the crucible was half full, Rosen activated his alchemical power and began to make it.

He first made a ruler.

The barrel of the spiral spray gun works in a harsh environment and will soon be severely deformed, so this ruler can truly represent the standard length. In order to avoid errors, the length of the ruler must be consistent with that of the spiral spray gun, but the material properties are greatly different. The most important feature is that it will not be severely deformed due to changes in temperature and external pressure.

He made just a simple ruler, which looks like a long thin piece of iron.

Soon, the shape of the ruler was formed. Under Rosen's careful control, the length of the ruler was consistent with the barrel of the spiral spray gun, and the error exceeded the limit of the naked eye.

'I have a ruler, but I still lack scales. But how can I be as accurate as possible? ' Rosen frowned and thought.

The length of the ruler is 40 cm, and it must be accurate to at least millimeters. If the scale marking error is too large, it will be very painful.

After thinking about it, Rosen gritted his teeth: "40 cm is exactly divisible by 2, so I will use the dichotomy method to mark the scale. For the calibration of the middle scale, I will directly count the metal atoms!"

Do it as soon as you say it.

Counting atoms, of course, is not one by one. If you really do that, Rosen will not have to do anything else in this life. He just makes a rough estimate and controls the final error within one tenth of a millimeter.

Using this method, Rosen spent a full hour to engrave precise scales on the ruler. The smallest scale is 1 mm. The distance between each scale cannot be distinguished by the naked eye.

‘Huh~’

Rosen exhaled lightly, looked at the ruler with a frosted surface, and whispered: “Well~ you can call it ‘Rosen’s ruler’.”

He dared to guarantee that this must be one of the most accurate length measuring tools in the world.

With such a good ruler, the next thing would be much easier.

He continued to melt the molten iron and make the parts of the spiral spray gun.

This time, with the experience of making glass needles and gun barrels, and the help of drawings, Rosen worked very smoothly and basically got it done in one go.

However, the molten iron was still too heavy and very energy-consuming. Every time Rosen completed one part, he had to spend at least half an hour to recover his energy.

Taking advantage of this time, Rosen would start to work on Savizhao and start to answer his questions.

This cycle repeated until around four or five in the afternoon, Rosen successfully made 17 parts and heat-treated them according to the different performance requirements of the parts.

After the parts were ready, Rosen took a look at his alchemy talent tree, and found that under the third-level elemental friend talent, his proficiency had risen to 56%.

He was slightly happy in his heart: ‘Not bad, not bad. Although it is a bit tiring to mold the molten iron, the harvest is still not small.’

After everything was ready, Rosen did not start assembling immediately. He first took a piece of thick cowhide and carefully wrapped the ruler, and then carefully put away the parchment with the parts drawn on it.

The ruler is delicate and can’t be easily worn. The big spray gun is a killing weapon, and the drawings can’t be easily leaked. In Rosen’s mind, these two things are much more important than the spiral big spray gun.

After everything was packed up, he started the final assembly.

‘Click~Click~Ding~Ding~’

The metal collision sound was very crisp, and each part was precisely in place. It was quite smooth to assemble, without any stagnation.

Savi asked curiously: “Master, what is this? It looks weird.”

Rosen assembled the last part and said casually: “It’s a weapon.”

“Weapon? This shape, is it a warhammer?” Savi guessed.

Rosen laughed dumbly. Not to mention, if the barrel of the spiral spray gun is used as a hammer handle, the fat gun body can really be used as a hammer to hit people, especially the revolver where the bullets are loaded, which weighs 4 pounds. Together with other parts, it weighs about 8 or 9 pounds, which can easily smash people's heads and bleed.

He chuckled: "Oh~ It can also be called a war hammer. I also gave it a domineering name."

"What name?"

"Thor's Hammer!" Rosen laughed with a bad taste.

Savi didn't see that Rosen was joking. He shook his head: "The name is domineering, but the shape doesn't look very handy. The power must not be very good. It's a pity for this good iron."

Rosen laughed in his heart, and he didn't say it out loud. He just said along the way: "It's really not good for hammering people. I just made it for show. Well, it's a little late today. I'll stop here for now. I'll go back first and continue tomorrow."

"Yes, Master. I'll take you." Savi immediately said respectfully.

"Hey~ I almost forgot something." Rosen suddenly patted his head.

"Master, go ahead."

Rosen took out a piece of parchment and handed it to Savvy: "This is a list of materials. It lists some medicines. You can find a way to get them for me."

These medicines are all common, and Savvy is a local and a glassmaker. He definitely has more connections than Rosen, which can be seen from the fact that he got wrought iron before.

Savvy took the list and looked at it. As he looked at it, his fair and fat face wrinkled into a big bag: "Master, I have generally heard of what you want, and I should be able to get it in Sunderland Town." , I’m just afraid that it will be very expensive.”

Rosen was overjoyed: 'Well, he is indeed better than me. I have no clue. For this guy, it's just a matter of money. ’

He immediately took out a money bag and handed it to Savi: "There is 200 rand in it. If it is not enough, ask me for more. Don't pay yourself."

Savi was startled for a moment, and his face showed emotion. He said seriously: "Master, this time it is really enough. Don't worry, I will prepare all the medicines for you tomorrow morning, and there will be a lot of them!" "

Rosen nodded with satisfaction: "Then I'll leave.

After that, he waved to Savi and left the glass shop with the assembled spiral sprayer.

After buying enough food on the way, Rosen returned to the courtyard, hid the big spray gun, and then carried the food and water into the wine cellar.

A lantern was lit in the wine cellar, and dim light came out, so Rosen walked directly in. When he entered the wine cellar, he saw Mary first, took one look at her, and said "Eh".

I saw that the abscesses on Mary's body had formed thick scabs, and the red spots that had not yet ulcerated had turned dark brown. The improvement was amazingly fast.

Rosen immediately looked at little Alice. Little Alice's recovery speed was even more amazing. The red spots on her body had basically subsided, leaving only patches of brown pigmentation. Her eyes also became quite bright. When she saw Rosen, she trotted over. , stretched out his arms happily: "Brother~Brother, look, look, my illness is cured! My illness is cured!"

Rosen was happy and surprised. He really couldn't figure out the reason, and it was impossible to dissect the two women and study them carefully. After thinking about it, he could only scratch his head and said, "Then let's continue the treatment."

This time, neither Mary nor little Alice resisted at all. When the needle was poked at their bodies, they just groaned and endured it. In their eyes, this shiny needle has become the most magical thing in the world.

After the injection, Rosen carefully checked the blood of the two women. The results were equally surprising. The drug concentration in the blood of both women was at normal levels, while the Treponema pallidum was very small and could almost no longer be found.

It's really amazing.

Rosen completely let go of his worries. He took out the food and said, "Here, let's eat."

The two women were obviously hungry. After getting the food, they started to eat voraciously. Seeing how delicious the food was, Rosen's appetite improved a lot.

After eating and drinking, Rosen yawned and prepared to go back to his room to rest. Just as he was turning around, he caught sight of little Alice's face from the corner of his eye. The little guy was looking at him expectantly, as if he wanted to say something to him.
