Vol 2 Chapter 355: book

"Bo Yuan, although this building is good, but ..." Liu Bei took Liu Yi, Pang Tong, Guan Yu and others to do the work of inspecting residential houses for the last time. Looking at the five-story residential building in front of him, Liu Bei suddenly thought of a problem. Looking at Liu Yi said: "People want to make a fire to make rice and draw water, how to solve this?"
It ’s also that Liu Bei started to make his way slowly. He lived a hard life and knew that people ’s lives were not easy. If they lived in their houses, there would be no problem, and manpower would be able to complete it. But you still expect ordinary people ’s houses to carry water for you. , And how to make a fire at home? Did not see the chimney.
"The protagonist knows what the water tower is for?" Liu Yi pointed to the water tower that was four or five feet high in the distance, and laughed.
"Water Tower?" Liu Bei looked at it doubtfully. There were more than 30 such water towers in Xiangyang City. Liu Bei always thought it was a warehouse.
"An interesting discovery recently, the water in the water tower is introduced into the residential house with bamboo pipes, and then a gate is installed. When the water is used, as long as the building is not higher than the water tower, the water in the water tower will automatically flow over. The weight is related, and it can only function for more than four feet at most. If it is high, it will not be able to get there. Each of these residential buildings is a three-bedroom and one-hall layout. There are special kitchen rooms and latrines. The drainage system washes away and passes directly into the septic tank outside the city through the bottom sewer to intentionally make fertilizer to irrigate the farmland. "
It is impossible to compare with modern times, but the principle of the toilet is not difficult, and it does not require much craftsmanship, and it is squatting, just flush directly, but if the toilet does not have the odor elimination attribute, then there is no way.
After so many years, Liu Yi's utilization of water is no less than the level of the previous life. Of course, there is no such thing as a high-pressure pump, and the current level cannot be achieved, but it is made by the pressure of the water itself. The water tower is still okay to be drained from outside the city and poured into the water tower. Among the natural works, Liu Yi has detailed records of the use of hydraulic power and some problems, principles and utilization of hydraulic pressure. Most of the artisans present I know some things, but Liu Bei is basically a layman, so Liu Yi explained it in more detail.
"In fact, this usage is used in Yueyang City and the fishing village. The bath is using this method, but there is no water tower, and Yueyang does not have such a high residential building."
The residential houses in Yueyang are at most two-storey small households, and there is no need to build a water tower. It is enough to build the toilet on the first floor.
Rao is so, Liu Bei is also a little amazed, with a little joke: "The people in Xiangyang City are blessed, I am afraid that the work and diligence of the North and Central China are not as convenient."
"These things are well documented in Tiangong Kaiwu. If someone is willing to study them carefully, it is not difficult to design and build such a city." Liu Yi said with a smile. Now the technology is almost perfect in theory, and practical cement These raw materials are available, and the crane is also made, read through and understand, and people with some basic experience in this industry can almost make it, but the built city is not the attribute bonus of Liu Yijian ’s city, speed It is impossible to compare with Liu Yi. After all, ordinary people hire people without Liu Yi's ability to turn so many people into good craftsmen.
"Tiangong Kaiwu? Already a book?" Liu Bei nodded his head. He knew that Liu Yi had been constantly improving this book since many years ago. When he was fighting in Shuzhong, Liu Yi had to fight every day. As long as Liu Yi had time, He would bury his head in writing, even when it came to supervising the construction of the project, Liu Yi would always take a blank bamboo slip or write directly with paper, but he had never seen Liu Yi finish it, so Liu Bei did not know the specific progress.
"Huh." Liu Yi thought for a while and thought it was a good opportunity to advertise. He took out a book from his arms, not a bamboo slip, but a printed version made of paper. Nine volumes, from easy to difficult, the first volume is more about some basic mathematical calculations.
Liu Yi handed over the book to Liu Beidao: "It is just the first edition, and may be revised in the future. If the protagonist has time to give some comments, this is the first book."
Liu Bei did not refuse, but just looked at the books with curiosity. About the paper books, Liu Yi had mentioned it with Liu Bei long before the Battle of Chibi. But Liu Bei and Zhu Geliang always felt that the timing was not right. There was no refusal, but Liu Yi obviously did not stop. The book in front of him is a book, which makes Liu Bei somewhat curious.
The paper is not the kind of Caihou paper I saw before. It is not conducive to printing, and it is not convenient to divide it. It is easy to stick together. This paper was made by Liu Yi after many experiments and polishing. Similar to the large white paper of later generations, the surface is very light, and each sheet is also very thick, easy to turn pages.
Turning over the book, compared to the words on the bamboo slips, the words recorded on the books are much more laughable, and the big words on the thumb, usually a few pages can be put on a roll of bamboo slips.
The first volume is all about some arithmetic operations. Liu Bei also knew that Liu Yi came up with a set of symbols to replace the numbers, but he did n’t study much. As for the symbols of addition, subtraction, multiplication and division, he did n’t even understand it. The basic course things were brought to Liu Bei in front of me at this moment, and looked like a book of heaven.
For a long while, Liu Bei rubbed his eyes, and looked at Liu Bei with a wry smile: "Bo Yuan this book ... Bai cannot understand it."
Pang Tong took it and looked at it curiously. He had a discussion with Liu Yi, especially Guan Yu's numbers and symbols. Pang Tong followed Liu Yi to get it. He looked at this moment and wondered: "It's not difficult to understand , Are some basic mathematical algorithms. "
Liu Bei looked a little embarrassed, the air became a little quiet, Liu Yi's speechless support, smiled and said: "It's not that the hero doesn't understand, but the hero doesn't know the meaning of these digital symbols and arithmetic symbols, so it's difficult to understand. , In fact, these symbols have some other ideas. "
Liu Bei took the opportunity to divert the topic: "Oh? Bo Yuan and say?"
"Before these numbers have been promoted, they can be used for information transmission. The detailed work we sent to Central Plains or Jiangdong can use this symbol to transmit information."
Liu Yi took out an analect from his arms to explain: "For example, only 365 is written in the intelligence, which is the third page, the fifth character of the sixth line. In this way, even if I pass the intelligence passed by the enemy, etc. And they wo n’t know what we mean.

After a long time, it will definitely be cracked. After all, as a detailed work of receiving intelligence, you must know the meaning of this thing, but Liu Yi took out the Arabic numerals, which was not for intelligence.
Liu Beiwen ’s eyes brightened. If it was placed a few years ago, it would definitely not be used. That ’s a big place. What to do with these bells and whistles, but now, Liu Bei, as the second most powerful prince today, has a large territory It has passed the hardest time for starting a business. Now Liu Bei has begun to gradually formalize his influence and supplement some functional institutions that he does not have.
In addition to helping Liu Bei manage the rear in Shuzhong, the most thing Zhuge Liang has done now is to set a set of laws suitable for the situation at hand, the facts inside the Liu Bei Group according to the Han law, and intelligence, such things as Liu Bei used to be. Concerned, but now, Liu Bei also wants to imitate Cao Cao, establish a special intelligence agency, and inquire about the news of all parties. Liu Yi's method can be said to have come in time.
"Bo Yuan, how many books are in your arms?" Pang Tong looked at Liu Yi's chest with some curiosity. Although the book is not as cumbersome as the bamboo slips, the content of a book can be far more than the bamboo slips, but also Not a thin piece of paper.
"Just these two." Liu Yi said: "Tiangong opened things from easy to difficult, divided into nine volumes. In the Yuxiang Academy, corresponding to different students, how can I bring all nine volumes on my body?"
"This is the only one, and there are ten thousand words?" Liu Bei asked with a smile while groping for the exquisite book.
"Almost." Liu Yi nodded, he had not calculated, how can I know so much.
"How about the cost?" Pang Tong asked abruptly.
Liu Yi thought for a while and said, "If such a book is sold, it will be about three hundred dollars."
As for the cost, it's really not expensive. Ten or so money is skyrocketing. Because it is mass-produced, in fact, the manual fee plus the material fee is not much, but it is too cheap to sell it. After all, this year's knowledge is very good. Shen Sheng is also very serious. When it comes out to do business, some people think that it is tarnished knowledge, tainted sages, if the sale is too cheap, then I am afraid that the world's scholars will not agree, this is not anyone can buy it?
In fact, this year and month, if you really want to sell a book, do n’t care about the cost ~ EbookFREE.me ~ When you sell it, just call it in Guili, even if there is no bargain, there will be 300 yuan, Liu Yi estimates that there will be someone Dissatisfied.
"Is it too light?" Pang Tong frowned at Liu Yi, not only him, but also Liu Bei, Guan Yu and others felt that the price was too cheap. I didn't see Guan Yu holding a spring and autumn all his life. Rabbits and horses are not much different.
"I thought so. The price is such a price, but it is only sold internally. Those who are successful in the country can buy it. Generals can buy it, and it is limited. In addition, it can be set up in various cities. Those with the heart of learning read it, but they cannot take it away. In addition, some talents can also give books if they can come to vote! "Liu Yi thought about it, and direct promotion would not work, so he had to take it slowly. Tall gifts, and style.
"In this way, it can indeed attract a lot of talents for the main public!" Pang Tongwen said with a bright eyes, nodded with a smile.
Liu Beiwen Yan looked at Liu Yi and said: "I don't know how much Yuan Yuan is in his hands, like how many thousand words are there?"
Liu Yi: "Enough."
Liu Bei: "..."
