Mathematics is naturally mathematical knowledge, although Ruya sorted out these mathematical knowledge can not be called textbooks, but it is also very extensive, small tract addition, subtraction, multiplication and division and ninety-nine multiplication table, as big as a complete high school solution function problem detailed explanation and only know what it is and do not know why it is the answer to the strange question, as well as all those he remembers, what Pythagorean theorem, trigonometry law and other kinds of mathematical formula laws, in short, all the things he came up with about mathematics are stuffed into it.

Not to mention physics and chemistry, all the knowledge that Lu Ya can think of and have something to do with them is recorded in it, but he is not a science student, and Lu Ya who has not gone to college really knows very little about these two knowledge, and there are very few things recorded in it, and most of them are like water is denser than oil, salt will turn into hydrochloric acid when it meets sulfuric acid, magnetic power generation, Crude oil can be distilled to get different oils, alkalis and acids to produce carbon dioxide and the like, and there is no explanation why, mainly because ・・・・・・ Luya doesn't know why.

The records in nature are all natural laws that Lu Ya is familiar with, such as why leaves fall, why people yawn, why sunflowers always face the sun, why snakes can walk without feet, etc., Lu Ya didn't know if these things were useful, but he still had people write them down.

In the last miscellaneous, Lu Ya is really not good to classify it as this name, and don't look at this name is inconspicuous, in fact, what Lu Ya values the most is the things recorded in this miscellaneous, and the most paper used to record miscellaneous items is not as much as these miscellaneous items.

The reason why it is called miscellaneous, because the records of the things in it are complex and simple, for example, on the first page of miscellaneous items is a more realistic picture of a bicycle, and the blank space also has the wheels, bearings, chains, flywheels, cranksets, etc. of the bicycle are drawn in a single concrete way, some of the names are marked, and those who don't know the names are not written, and finally the functions and use of the bicycle are also written in detail.

On the second page, a diagram of the structure of several iron pillars and several iron wheels is drawn, and only the train transmission device is written on the top of the picture, and only how these wheels are driven by several transmission rods is given, and the main engine part is not mentioned at all.

After that, there are even more messy things, a simple press and pop-up button on the trail, as large as the simple model of the tower crane, and so on, basically recording most of the things on the earth that Lu Ya can recall that he can understand some structure, and he doesn't care if he can build it in the future, just record all these things.

And with the improvement and increase of these five 'great works', the craftsmen who often came to watch and study looked at Lu Ya with more and more admiration. The knowledge that Lu Ya has put people together may be casually thrown at a person on the earth who has lived in normal human society for twenty or thirty years, and will sneer at it, because this knowledge is the most common and common thing that the public usually hears about, and there is nothing to show off.

But those craftsmen are different, with the civilization level of the backward orc world, these things given by Lu Ya undoubtedly subvert their three views, if any other person says something to these people, they are standing on a big ball, and they don't say it, and they still revolve around the sun and so on, they will treat it as a neurosis, but when Lu Ya really wrote it in that nature book, they became convinced.

Because after these days of research and study, they have confirmed too much knowledge of natural laws and physical chemistry that they didn't even dare to think about before, and they have gradually understood that the world they live in is full of natural laws and physical rules, and many superstitious ideas in the past have gradually been broken, and the same previous ideological imprisonment has gradually been opened.

I dare not say that these craftsmen stand at the top of the craftsman industry in this continent, but these people's thoughts are sublimated countless grades than all the craftsmen on this continent now, and this has laid the way for their rapid growth in the future.

As the finance minister of the Blackstone tribe, House naturally often came to the institute to report various things to Luya, who was almost growing in it, and naturally he accidentally saw the five great tomes that had been sorted out and could be updated at any time.

At the beginning, House was completely curious, wondering how Ruya, a guy whose head was full of magic crystals, could take out so many things, and even sometimes House scolded this Luya for recording those classic yellow jokes that he had never heard of before.

However, when he inadvertently opened the mathematics record, his eyes bulged out violently, like a big-eyed monkey that had been choked by the neck, and as he looked at it row by row, his eyes gradually changed from the incredulity at the beginning to shock, and finally directly reverence, his hand turning the paper trembled a little, and the gentle movements and pilgrimage-like expressions all showed that he had been conquered by the things recorded in this mathematics book.

"This, this, this, all written by you"

When House found Rouya with the math book, the meaning in his eyes was obviously telling Rouya, hoping that Rouya would say no.

Seeing this, Lu Ya also smiled, as if he had fulfilled his wish, and replied "No"

"I knew it couldn't be your ・・・・・"

It seemed that when he heard this, he immediately breathed a sigh of relief, and was thinking about asking Lu Ya who wrote it when Lu Ya spoke again.

"I asked others to write this, and everything in it was all I thought of, how about it, worship me, hurry up and sing about conquering"

“・・・・・・・”

Since then, Luya has been able to see House in the institute almost every day, and every day House will take his notebook to the institute to learn and verify the knowledge of mathematics, and will urge Luya to continue to add new knowledge to it from time to time.

However, House never believed that what Luya said was Ruya's own idea, but even so, as he studied further, House became more and more incomprehensible to Luya.

As a human businessman with extraordinary talents, House is naturally very proficient in mathematics, but after seeing Ruyana's mathematics, he realized that the things he had learned before were really not worth mentioning compared to this, and the things recorded in that mathematics were so profound that House often felt that he was looking up at the mountains in front of this book. And when he thought that these things were all from Lu Ya's mouth, he even sometimes wondered if Lu Ya was really a beast god, otherwise how to explain where Lu Ya knew these things.

Regardless of what House thought, Ruya continued to live his life every day, and now he had recorded almost all the things he remembered most clearly, and the number of recorders behind him had been reduced to one, mainly to record some of the inspirations and things he occasionally remembered, and he himself began to intersperse with research teams to see if there was anything he could do to help.

On this day, Lu Ya, who was walking to the cafeteria with the old man Tie to have lunch, and was still discussing the problem of pouring the cannon pipe on the road, suddenly remembered that House, who used to read books in the institute every day, seemed to have not appeared for several days, and he was puzzled, so he was ready to send someone to see what House was doing.

As soon as Lu Ya and the Iron Old Man sat down, two orc boys came up with a few side dishes and two large bowls of rice. Looking at today's lunch meal, three seasonal vegetables, and a plate of boiled elbow meat, Lu Ya smiled at the old man and said, "How is it, on the hour?"

The Iron Old Man glanced up at Ruya and shook his head, then began to pick up the food in his mouth.

Feeling bored, Luya shrugged his shoulders and swept his eyes around, and suddenly found a figure walking in from the entrance of the cafeteria, and after a closer look, it was House.

"Hehe, it's just right, come on, do it quickly, kill two wild boars at noon today, taste this braised elbow, chirp, it's so fragrant" Lu Ya greeted, and there was immediately a person around him who thought that House had filled a pair of chopsticks.

The old man also raised his eyes to look at House, and then picked up the bowl and thought that there were some dishes in the bowl, and then went to the side to eat together, Lu Ya couldn't help but roll his eyes wildly when he saw this, even if the old man was eating, he was thinking about his tinkling steel, it was not easy to make him have fun with people.

After retracting his gaze from the old man iron, Ruya grinned and looked at House, who was already sitting opposite, and said, "Why have you been there for the past two days, and I can't see your shadow?"

"Something is a little bit wrong~Woo~ I went to take a look~ Woo~ I came back after figuring it out~~" House said as he directly took a braised elbow and gnawed it, and the Ruya who looked at him couldn't help but despise him, but as soon as he heard that there was a situation, he still got upright.

"What's the situation" Ruya also tore a piece of elbow meat and put it in his mouth and chewed it, since House was in the mood to eat, he also knew that things would not be in a hurry.

"Hehe, didn't you come back from Boulder Cheng last time and say that you offended those chambers of commerce, and the revenge of the people is coming" House grinned, a piece of hoof tendon tucked into his white teeth for Ruya to see.

"Can you look good at that meal?" Luya gave House a wide roll of the eyes.

"Don't you ask me how they retaliated?" House looked at Ruya in surprise.

"You're not in a hurry, I'm in a hurry, cut~~" Lu Ya replied.

"Uh~~ Then I won't say it, hey~~~ You give me your elbow, I say, I say~~"
