The Last Alchemist

Rosen was startled by Savi's reaction.

"What are you kneeling for? Get up quickly!"

Savvy was still kneeling on the ground motionless. He hugged Rosen's calf tightly and refused to let go: "Master, I can only understand half of the manuscript you gave me, but I am not blind. There is something in this manuscript." The glorious secret. This is beyond the wisdom of mortals, and it is absolutely impossible to truly understand it with my own mind. I beg you, as long as you are willing to accept me as your disciple, I am willing to support you for the rest of my life!"

When he said these words, Savi spoke sincerely, his eyes were wild, and he looked like he was ready to fight with all his strength.

Hearing Savi's words and looking at his fiery eyes, Rosen moved suddenly.

“To truly demonstrate the power of science, it is far from enough to rely on individual strength. What I can do is spread wisdom and awaken people's curiosity about the world. Since I am a scholar, why should I be stingy? ’

Thinking of this, Rosen nodded slowly: "I will stay in Sunderland for a while. During this time, I will at least help you fully master the method of making a magic mirror. Of course, as a price, you must help me do it. something."

Savvy was ecstatic, and his fat body was shaking uncontrollably. He took a step back on his knees, and his fat body fell to his knees on the ground: "Master, I am extremely honored to serve you!"

"Well, now I want you to fuck me first."

"Master, you, you said, I will do my best." Savvy was a little nervous, afraid that Rosen would make harsh demands.

"I need about 20 pounds of iron, preferably wrought iron. If not, pig iron will do."

Rosen needed the iron to build the parts for the big spiral nozzle.

Upon hearing this request, Savi was immediately relieved: "No problem, I'll go find it now. Don't say 20 pounds, just 30 pounds or 40 pounds. It's no problem."

Isn't it just 20 pounds of iron? This is not simple.

Rosen smiled, took out 50 silver rontes from his pocket and handed it to Savi: "You can use this money to buy iron."

Seeing that Savvy wanted to refuse, Rosen insisted: "Take it, keep your little money just in case."

"Yes, yes, thank you, Master." Savvy took the silver franc. Since he gave Rosen 1,000 silver francs yesterday, he did not have much savings left.

After taking the money, Savi immediately left the glass shop and strode towards the blacksmith shop in the town.

Rosen didn't care where Savvy would get the pig iron. He unfolded the parchment, picked up the quill, and began to draw the metal parts needed for the large spiral nozzle.

Rosen already had an idea for the basic shapes of these metal parts. But if you just rely on fantasy, when you use the power of alchemy to construct, it is easy to make errors. If you draw the specific shape of the part and mark it with precise dimensions, the impression in your mind will become very vivid and concrete. It also becomes quite precise when molded.

There are not many parts for the large spiral nozzle, no more, no less, exactly 17, and Rosen quickly completed the drawing.

After drawing the basic shape of the part, Rosen suddenly discovered that he had an imminent problem that he had not yet solved.

‘Hi~ Oops, I don’t have a precise ruler at hand. ’

It was easy to make a single part before, but now we have to assemble 17 parts. If we don't have a ruler, although it is not impossible to make parts that meet the size, we will definitely make frequent mistakes and consume a lot of extra energy and time.

Immediately afterwards, Rosen discovered more problems.

'No, not only is there no ruler, there isn't even a standard unit of length. ’

In this world, measurements of length, mass, time, etc. are very imprecise, and the standards are not uniform.

For example, the most commonly used units of mass are kilograms, pounds, pounds, and ounces. There are also Parason pounds, Cowell pounds, Berkeley pounds, and even little Sunderland has one called the 'Blackfish pound', which makes converting between them extremely troublesome.

Then, Rosen discovered more problems: ‘Forget it there is no standard unit, and the calibration mechanism is lagging behind. ’

It is common sense that any unit of measurement must be calibrated frequently in order to be accurate during propagation.

However, because the calibration mechanism is backward, even the same mass unit will have huge deviations from each other.

For example, the Parason Empire used Parason pounds when collecting taxes from various places. For calibration, the empire set up four stone balls of the same size in four cities in the southeast, northwest and northwest. When the stone balls were first made, the weights were very similar, but a few years later, due to different climates, the stone balls in different places experienced different losses, resulting in huge differences in Parason pounds in different places.

Rosen was lost in thought: ‘Now I want to make a large spiral sprayer, and the assembly of the parts is not too complicated. If you make other things in the future, hundreds or thousands of parts will be involved. If you don't have a good ruler. During the final assembly, there will definitely be so many mistakes that people will doubt their lives. ’

‘No, this won’t work. I have to determine each standard unit and the method of correcting the error. ’

‘Well~ first define the most basic and commonly used ones. What are they? By the way, there are time, quality, and length. Let me define time first. ’

Just do it if you think of it.

Rosen thought about it carefully, then opened the parchment and wrote on the paper: "Standard time unit: second, accurately defines the frequency of light emitted by cesium 133 atoms when they transition to a specific energy level. Wait, this definition does not Problem, but with the current technical level, it’s impossible to measure. Damn it, it’s so difficult.”

He remembered clearly that on Earth, the most standard second was defined by the frequency of light emitted by cesium-133 atoms when they transitioned between two specific energy levels. Specifically, it seems to be more than 9.1 billion times the light period, which is 1 second.

The problem is, Rosen does not have such cesium 133, nor does he have precise measurement methods, so even if he knows the way the earth defines the basic time unit, it is in vain.

After struggling for a while, Rosen had to accept the reality: "Forget it, the parts of the spiral nozzle don't need to be very precise. For the time being, I only need to use the unit of length. Just use the physical object to define the standard length."

With this in mind, he took out the prepared barrel, gestured back and forth, and then wrote on the parchment: "Standard length unit: meter, definition: 1 meter is equal to 2.5 times the length of the spiral spray gun barrel. "

This is the only definition that Rosen can do. He can only let go of other units that he won't use for the time being.

After defining the standard length, Rosen used the barrel as a ruler to calibrate the length of other parts, which made things a lot easier.

More than half an hour later, Rosen had completed drawing all 17 parts.

After another ten minutes, Savi also came back, holding many rusty iron tools in his hands, including iron pots, hoes, broken plows, and an abandoned carriage axle.

"Master, I couldn't buy good iron, so I only have these things. Do you think it's okay?" Savvy looked at Rosen uneasily.

He originally wanted to buy iron from the blacksmith shop, but instead of buying iron, he was scolded by the old blacksmith. He had no choice but to go to ordinary people's homes to buy iron.

But for ordinary people, these ironware are valuable items and indispensable daily necessities that will not be sold easily. In order to buy these iron tools, Savi had to pay a high price.

As a result, after getting through, he not only spent all the money given by Rosen, but also put in more than 40 rand himself.

Rosen had alchemy skills at hand and was not picky about the quality of iron. He stepped forward to check and found that although there was a lot of rust on these things, most of them were wrought iron, which was better than the pig iron used in Savvy's hollow iron pipes. "No," he nodded: "You can use it, but I'm afraid the money I give you is not enough to buy these irons, right?"

He just doesn't understand the market, but he's not stupid.

These days, for ordinary families, ironware is the most valuable necessity. Good ironware can be used as a family heirloom. In today's troubled times, no one would sell iron tools easily.

Savvy said hurriedly: "It doesn't cost much, as long as you are satisfied, Master."

Since Savi didn't mention it, Rosen didn't dig into it.

After thinking for a while, he said: "Then I will continue working. You continue to read the parchment. If you don't understand it, figure it out first. You must think about it carefully. If you really can't figure it out, mark it out and wait until I'm done. , I will explain it to you carefully."

"Hey, okay." Savvy nodded hurriedly.

Please collect and recommend.
