The operation of the logistics distribution center of the Protestant Order is booming, and a large number of materials are traded on the spot in the logistics center, which can be exchanged for hard currency such as silver coins that are convenient for transportation or directly exchanged for the resources needed.

One night, a mouse burrowed into a laboratory in the west of the city, making a sound of something smashing, and soon a loud noise woke everyone up, and the wave of air spread out and shattered the glass of several nearby houses.

Leo blew his nose and soaked sleepy-eyed, he really didn't sleep well last night, but fortunately, he repeatedly confirmed that it was just an explosion, not an enemy invasion, otherwise he would never sit and doze off so comfortably.

"Your Excellency has found out that a private laboratory in the west of the city exploded, causing damage to 12 houses."

"What kind of laboratory do you do?"

"It is said that it is a study of acidic liquids, and the one you commented on in the daily newspaper before"

"Oh... The two brothers' research room."

Previously, the paper of the two brothers Schoen and Vière was published in the daily newspaper Drifting Snow, they found a way to make ferrous sulfate from high-temperature calcined pyrite, and after studying Leo's paper on chemistry, he obtained sulfuric acid through the dry distillation of ferrous sulfate, and Leo also did not hesitate to give five star reviews.

"Call those two to me"

Although the incident happened in the middle of the night and there were no injuries, the destruction of so many houses could not be counted like that.

The two brothers naturally knew everything about Leo's questions, and did not dare to hide them in the slightest, but they had no clue, and the two were not in the laboratory at the time of the incident, and they did not have any explosives hoarded in it, suspecting that someone was sabotaging it because of jealousy of the results, and implored Leo to administer justice for them.

……..

Is it really because he is famous for his research on acidic liquids and is jealous, so he blew up the laboratory? The inventory of gunpowder has also been carefully counted, and it has not been less, and it has almost become a headless case under the verification of multiple parties.

However, these two brothers recently purchased a large amount of nitrate in the name of the laboratory, not to mention that only nitrate cannot synthesize black powder, I blow myself up? It's impossible to think about it, Leo suddenly felt that something was in his mind, and he hurriedly summoned the two brothers.

"Have you been working on any new acidic liquids lately? And it's related to saltpeter? ”

The two brothers were stunned for a moment, showing incredible expressions.

"How do you know, my lord, that we did get a new acid by refining saltpeter, because it was obtained from saltpeter, and we were going to name this acid..."

"Nitric acid!"

"Yes, yes, it's nitric acid"

Nitric acid and sulfuric acid ...... Sure enough, this is the recipe for nitrifying explosives in later generations! It didn't take much effort to get it!

"Do you remember how much you prepared at that time, I want the ratio of the two acids in the laboratory at that time?"

"To remember is to remember... But this is the same as the explosion in the lab..."

"Nature is related"

Leo stood up from his chair and looked at the two of them meaningfully.

"Recently, I am planning to gather scholars and craftsmen from Drifting Snow City to set up a scientific research institute, and those who can enter it are naturally cutting-edge people in various disciplines, and the remuneration will be very lucrative."

The two of them were stunned for a moment, chewing on the meaning of this sentence, and suddenly understood and showed joy.

"Congratulations on becoming a member of the Snowdrift Academy of Science"

……

Mange became one of the few full-time teachers in Drifting Snow City, and was named the principal of Drifting Snow City Elementary School, and after arriving in Drifting Snow City, he was surprised or surprised.

Originally, reading was a privilege that only the children of the nobility could enjoy, but when it came to Drifting Snow City, even ordinary people could let their children come to primary school to study, but the price was only a few copper plates.

In addition, this arithmetic method has always been learned by talented people, and it often takes a master to train a master to train a bookkeeper for several years, and here, children can quickly complete a large number of basic operations as long as they are familiar with the multiplication formula.

What's more, what is addition, subtraction, division, multiplication, and calculation, in order not to fall behind the progress of the teaching, I can only make up for these, and after a month, I always feel that there is a lot less hair.

……

There is no lathe parts grinding all by hand, just the beer belly of the hammer has gone down half, order after order, Leo's brain eruption is simply more diligent than the sprinkler, Leo is looking at his plump waist recently, a little weak.

"Brother, don't say anything...... Tonight's celebration feast! Raise wages! ”

Brute Hammer blew his beard and glared at Leo.

"Even if you still have a conscience, I heard that you have recently raised a few beef cattle...."

“……”

The original guns in Drifting Snow City used the most primitive black powder, although it was easy to prepare, but the disadvantages were also very large, the amount of use was large, the smoke was large, the key was to paste the gun chamber, and the backlog of carbonized materials caused a musket to be rebuilt in a short time.

Leo wanted to get an automatic rifle, even if it was bolted, but unfortunately the black powder really couldn't be carried, and now these are not a problem, with the base of nitrified explosives, plus the understanding of this aspect in the previous life, the research institute quickly completed the production of the first batch of nitrocellulose.

The end result of the brutal hammer labor was a prototype of this bolt-action rifle, built by hand, and even the ammunition was finely polished.

The shape is modeled after the classic 98K, and the effective distance can reach six or seven hundred meters under the test shot, but unfortunately there is no serious lathe and cannot be mass-produced.

Due to the pressure of the empire, the number of displaced people has also increased dramatically recently, and many people think that the Northland will be safer, which makes Leo have some bad premonitions and decide to take precautions.

"Brother, I'll discuss something with you"

As soon as I saw Leo's hippie smiling face, I shouted in my heart, this grandson will definitely pit my old man and squeeze my old man's labor, I can't agree to anything you say!

"You see I actually have a drawing here, don't worry! This one is definitely easy to make! Few parts and simple structure"

The brute hammer could only take the drawings in disbelief, it looked quite simple, and it was very similar to the previous musket structure, but the strong warning in his heart still warned himself that there might be fraud?

"Look, it's pretty simple, isn't it, don't worry, it's definitely going to give you a holiday, I swear in the name of His Highness Fran"

Leo patted his chest and reassured, looking like he was swearing, and the hammer carefully confirmed the structural diagram, it was indeed very simple, and there were no overly delicate parts, and he was also relieved in his heart.

"Okay, I'll squeeze my old man, and after finishing this order, I'll arrange a stay in Blackstone Town and a hot spring tour for me and the rest of the people in the workshop."

As he spoke, he threw the drawings in his hand to the workshop apprentices behind him who were walking and floating.

"It's easy to say, remember to come to the celebration banquet in the evening, and make shabu shabu today!"

"Don't go back!"

Leo ran away without touching his feet, and he always felt that this kid was a little strange today, and when he looked back, a group of apprentices were silently covering their eyes and crying.

"Master...... This drawing, spicy eyes"

Brute Hammer took a look at it, only to find that there was a second page of this drawing, which talked about specific values and ammunition materials.

Boy! The total length of 2.5 meters is expected to weigh more than 600 kilograms, and the shells will also cost dozens of kilograms.

After these things are made, I am afraid that I will have to work overtime for a few weeks, and the hammer stands in the wind, looking up at the sky to keep my tears from flowing.

This drawing is really spicy to the eye.
