The Hero Who Troubles the Heroes

Reading the atmosphere is one of the secrets to living a long life.

Seeing that the headmaster who had just returned looked bad, Charles immediately made an excuse and ran away with Artoria.

The next two days are the time for new students to choose courses. Most of them are choosing the courses to study in the next semester.

The paper for the written test has been sent back, and this time, the thorough examination let the newcomers know the shortcomings that they need to make up.

This is also the reason why the chief students can choose courses freely, because it shows that they have no shortcomings.

There are six grades in the academy, and the small buildings of the chiefs of each grade are in one area.

The building is not big, only two floors, but it is a symbol of identity.

Charles' small building was a little far from Artoria's, and the two separated at the intersection.

A certain person took the sample plan proposal Cearturia and said, "You are very good at copywriting."

Arturia rolled his eyes at him and took the sample plan.

The furniture in the two of them's small building was ready-made, and they were cleaned immediately. Reschee sent the three black-haired maids over to help.

Although Reschee is excellent, she is not the chief. She and Maya live in the same double room.

Originally, Maya could be the chief, but she fell asleep during the written test.

In the past, the three maids and sisters, who could only rent a house on the commercial street, now simply live in the servant's room in the Yilou.

As for the rent, when Charles came back, they were conspiring to do some harm to Master Yi together.

"What are you talking about?" Charles saw them whispering when he entered the room. Out of politeness, he rarely took the initiative to eavesdrop on what others said.

"Hei Changzhi" said the maid, "We are discussing the master's book."

Charles gave her an "oh" and asked her, "Can you understand this book?"

He was talking about the book "Why Magic?" , according to the plan, this book will be released with a big news.

The three maids and sisters said that the book is easy to understand, and there are many contents that they have not heard before, but it seems very reasonable.

Charles felt very satisfied, and asked them to prepare lunch for themselves and take it to the study later.

Sandwiches, hamburgers, chicken rolls are very simple to make. The maids will make them under the guidance of someone. Today's lunch is a few hamburgers and a cup of herbal tea.

Charles sits behind his desk, eating a hamburger and thinking about his next work.

Climbing the skill tree is not an easy task, he can only open up the first-level skills, and the subsequent development depends on the locals.

The most important of these are papermaking and printing.

This planet is too remote for the gods to control, but the perennial war has made the development here unbalanced.

But the good news is that mathematics is well developed, because there are requirements for air cavalry throwing weapon ballistics, oversized crossbows, and large catapult launches, and mathematics has not been ignored.

But others are not so optimistic, at least the papermaking technology has not come out yet.

It's just that Charles is only talking about papermaking. If he really wants to open this technology, he has to ask Ji Shijun for help.

Although the signal here is not good and cannot log in to the Dreamland platform, it is still possible to send and receive emails through Reimu.

And the Slime Basin is mainly made of flax and bamboo for papermaking, and in terms of raw materials, the experience there is also suitable here.

Then there is printing. Whether it is movable type or block printing, ink is used. At this time, it is necessary to use suitable ink for printing. There is also a lot of knowledge in it.

This question was also packaged and sent to Ji Shijun to ask him for help, and when the big deal went back, he brought a group of succubus to him.

The capitalists are even willing to sell their nooses for profit, and they also bring free shipping, so what can Ji Shijun sell for the succubus?

Ji Shijun, who was far away for an unknown number of light-years, suddenly shuddered.

In addition to papermaking, the technology tree of the power system will naturally be opened.

The next question is still the old one. Industrialization is a rising process of chicken-and-egg. The problem lies in how the first chicken came about.

The Rurik kingdom has the foundation left by Philip, and before the advent of wind turbines, they were already using rough machine tools with human and hydraulic power.

While sheltering from a storm in a cave, Charles asked Maya about the level of industrialization on the planet.

Aside from the windmill, the biggest machines here are the hydraulic hammers and grinders.

Earlier, a certain person took the microscope to Leschel to imitate, but the craftsmen in the city shook their heads when they saw the thread for adjusting the position of the lens barrel. They couldn't do it.

After lunch was over, he picked up the handkerchief and wiped his hands. Ayi took the parchment and began to write and draw.

It is not easy to open the technology tree, and it is even more difficult to write the technology tree. It can only be pushed backwards with the goal of steam engine, internal combustion engine and magic motor.

He started with the steam engine, first decomposed the various components and their properties, and then analyzed how to produce these components. As a result, milling machines, boring machines, and planers appeared.

So he simply took a new piece of paper and drew the schematic diagrams of lathes, drilling machines, boring machines, grinders, gear machines, thread machines, milling machines, sawing machines, etc.

Thanks to the rise of the machine tool industry in the Rurik Kingdom in recent years, the content of machine tools has even appeared in the textbooks of primary school students. In St. Philip's Polytechnic University, "The Working Principle of Machine Tools" is a compulsory course. can draw them.

It's just that this planet has not developed a magical active substance that can be deformed under the influence of magic power, and someone can't do it either. As for how to develop it, it depends on the local people.

After painting, Charles patted his head, "How did I forget this?!"

"What did you forget?"

The sudden sound startled Charles.

Looking up, he found that LeBron didn't know when he was sitting in the chair opposite the desk, holding a copy of "Magic Why?" ".

"Ah...Headmaster." Charles hurriedly stood up to say hello, "Why are you here?"

According to his habit, he will remove the word "deputy" when addressing the deputy when he is not in the main position.

LeBron stroked the double ponytail beard on his chin. He didn't bother about the boy's name. Instead, he put the book in his hand on the desk and jumped off the chair. After finding the height problem, he jumped back on the chair and stood, and then owed Charles a little. Behind him, he said, "I'm here to apologize to you. After seeing the blower inside the anti-gravity Trojan, I knew that what you said on the spaceship that day was right. I was the turtle at the bottom of the well..."

"Please don't say that!" Charles said hastily. "I'm just a little clever, standing on the shoulders of giants."

He hurriedly changed the subject: "I have a question to ask, what is the smallest size that the ruler can measure now?"

LeBron didn't understand what he was going to do, but replied: "The energy is one millimeter, and there are public standards for the length and weight of various places."

Because of the long-term war, the weights and measures on this planet have been initially unified, otherwise the logistics system will be a headache.

"I have a ruler here that can measure to 0.02mm," Charles said.

"Why is the test so small?" LeBron was stunned for a moment, then suddenly realized, "By the way, the anti-gravity magic circle you made and the magic circle pattern on the wind-blasting iron barrel are all under one millimeter. !"

Charles nodded and said, "In order to miniaturize the magic array, a ruler with smaller precision is necessary."

What he forgot just now was the vernier caliper. He would not be able to play without it in the production of machinery in the future, so he took this opportunity to draw a pattern on the parchment, and then explained it to LeBron.

After listening to it, LeBron praised: "This design is very good, but there is only one question, how to draw an average of 50 identical divisions within the range of 49 mm on this vernier?"

His question also makes sense, because each grid on a 50-degree vernier is 0.98 mm, which cannot be measured with a ruler with a minimum graduation of 1 mm.

????????3

??????2????

????1?????????

?∠???????????1????????????2?????????3

Using a ruler and compass, Charles explained while drawing: "First draw a bottom edge, and draw a diagonal line at point o on the left."

"Then use a compass to cut a section of ob? on the oblique line, and then continuously cut b?b?, b?b? of the same length as ob? on the oblique line. You can cut dozens of sections as needed. Now that the paper is not enough, cut it first. Three paragraphs."

"The third step, draw a straight line connecting b? and the right end of the bottom line, which is b?a?."

"The fourth step is to pass through b? and b? to make a parallel line parallel to b?a?. These parallel lines and the bottom edge intersect at points a? and a?, respectively."

"In this way, oa?, a?a?, and a?a? are three equal line segments, and when expanded, 50 divisions can be drawn on a 49 mm line segment."

After listening to this, LeBron pulled his beard and said depressedly: "Oh, how did I forget the theorem of parallel lines bisectors!"

After thinking about it for a while, he said: "I can make this, hehe, it should be good to sell it to a workshop that makes arrows."

Then he asked, "Can I take this drawing?"

Charles replied with a smile: "Of course, you can also take these drawings and descriptions back and look at them, hoping to get the principal's opinions and suggestions."

Seeing that it was getting late, LeBron picked up the drawings of the vernier calipers and the drawings of those machine tools that Charles handed over and said goodbye~www.wuxiaspot.com~Charles wanted to keep him for dinner, but he squinted and slipped away.

It wasn't until someone came downstairs to find out why the vice-principal was slipping away, because today Leschel, Danya, and Maya all came over, and they didn't wear the academy robes, but all dressed up beautifully.

It was dinner time, and there was a stew of beef, potato wedges, and some peppers, fried chicken cutlets coated in egg liquid and flour, fried cheese in the same way, and The potatoes are peeled, steamed, smashed, and then put into the sausages to form a potato cake and fry together.

The girls have been busy with their own affairs for the past two days. In the past, only Leschel came to eat. Today was the first time that they all got together like this.

After Charles came out, everyone came to the restaurant to start dinner and chat about recent events.

The most popular news in the academy recently is that in the big stomach competition on the commercial street yesterday, Arturia won the championship. In the wine king competition, Skadi and another girl who looked exactly like her drank it all. There was no winner after drinking, and today Principal Duff and Vice Principal LeBron fought because of a machine.
