Late at night. Luan Yi was called by Cai Yong for questioning.

When I entered the room, I saw Cai Yong wearing a robe, holding a book and reading at night. His face was ruddy, his hair was damp, and he had apparently just taken a hot spring bath. Cai Zhao stood behind him, a pair of white and delicate hands gently rubbing his shoulders. Seeing Luan Yi pushing the door in, Cai Zhao smiled kindly at him. The beauty of the smile made Luan Yi, who was just over 8 years old physically but over 33 years old mentally aged, intoxicated.

Cai Yong gently placed the book on the table, and motioned for Luan Yi to sit next to him with a smile on his face.

Luan Yi acted according to his words and behaved humbly.

Then, Cai Yong asked about Luan Yi's schoolwork. said that he was asking, but in fact, he was testing his academic skills. Luan Yijun answered one by one according to the "correct answers" of Professor Cen Laofuzi in the college.

However, as an old-school pedant, the knowledge he received was inevitably a little outdated, and there were many fallacies in it. Cai Yongjun corrected it and interpreted the scriptures in detail to Luan Yi.

With the guidance of everyone in the world, Luan Yi can be said to have gained a lot.

Cai Yong couldn't help but sigh, "There are many ways to annotate the scriptures and history, and they are misleading!" If it weren't for the old man's guidance in advance, I would have almost mistaken you! ”

Luan Yi was also embarrassed. Then he praised Cai Yong's "Hongdu Stone Scripture" tablet for hearing and hearing. "Cai Gong's move is beneficial to the future."

"Hey......" Cai Yong sighed and said sadly: "It's a pity, it's a pity!" Although Yu Taixue's "Hongdu Shijing" can correct the classics, it is lacking in both the speed of dissemination and the breadth of circulation, and the effect is not ideal, but it is difficult to change the status quo of the deviation of the scriptures. ”

Through Cai Yong's deep frowns, Luan Yi could see that Cai Yong was really worried about the deviation of the thoughts of the hundred schools of thought. The atmosphere in the room suddenly poured out a thick sadness, and Luan Yi's heart unconsciously crumbled together. I couldn't help but turn my mind, looking for a way to help Cai Yong promote the correct solution in the memory of his previous life.

The room was suddenly immersed in a quiet that could be heard of a falling pin. Suddenly, a flash of inspiration flashed in Luan Yi's mind, but he couldn't grasp the essentials and had a headache. After thinking for a long time to no avail, Luan Yi calmed down and began to use logical methods to reason about countermeasures. The reason why Cai Yong is melancholy is fundamentally because the subset of classics and histories has different short sentences, and a piece of text can be translated into different contents, which causes ambiguity. There is only one way to correct him, and that is to select the most representative and convincing generalization from among these many explanations. This is exactly what Cai Yong is doing now, and the biggest difficulty he encounters is that his commentaries on the scriptures have encountered problems in the promotion channels, so that there are still scholars who cannot read his commentaries, and there are many such scholars. Among them are Luan Yi, as well as many students in Yingchuan College.

You must know that Yingchuan College, as a famous institution in the late Eastern Han Dynasty, has not even read Cai Yong's "Hongdu Shijing" by the scholars here, let alone other students in remote areas.

In addition, there is also a very important thing, that is, although Cai Yong's "Hongdu Shijing" corrected the translation of the classics, due to the limitation of the length of the stone tablet, there are still many important contents that have not been reflected in the inscription. It is not known from this.

So...... To sum it up. The problems Cai Yong is encountering now are: first, the promotion of ideas is blocked, and the channels are too narrow; The second is that the method is too restrictive and the information capacity is insufficient.

These two problems are the problems that Luan Yi urgently needs to help Cai Yong solve. "Channel, capacity ......" Luan Yi murmured again and again, and the fleeting light in his mind shone again. Pregnant! ”

Cai Yong's face was overjoyed when he heard this, he had actually guessed that Luan Yi, who was praised as a genius by the world, might have a way to solve the problem he encountered, but he never thought that Luan Yi would find the answer so quickly. Knowingly, he asked, "What's there?" ”

"Yi has a way to make the "Hongdu Stone Scripture" go back to life." Luan Yi said confidently.

"Come on." Cai Yong's excited eyes were red, and even his beard was curled.

"Why don't Cai Gong print the "Hongdu Stone Scripture" into a book."

"Printing? Printing! Printing. After listening to Luan Yi's words, Cai Yong, who was still in good spirits just now, was suddenly like a frosted eggplant, and his disappointment was beyond words. The old man never thought of printing a book. However, printing costs a lot for a while, and printing 10,000 copies is a sky-high price. Luan Xian's nephew is really difficult to do. ”

Cai Zhao behind Cai Yong also looked depressed. He originally thought that Luan Yi would come up with some bright ideas, but he never thought that the countermeasures that Luan Yi came up with were just ordinary.

"Cai Gong is not in a hurry, and there is a way to reduce consumption. Let's listen to Yi slowly. Then, Luan Yi smiled and calmly told Cai Gong. There are two reasons why printing costs a lot: on the one hand, engraving printing, each page of the book needs to make a special carved slate with corresponding content, and how many slate slabs are needed for as many pages as there are pages. Not to mention the salaries of craftsmen, the purchase of engravings alone costs a lot of money. What's more, in the engraving process, a page of a book is at least 100 words, and it is inevitable that there will be mistakes in engraving hundreds of pages. On a slate, as long as there is a word error, the entire slate will be scrapped, which will also greatly increase the consumption of silver coins to a certain extent. On the other hand, printed books, the content of the book always needs a carrier, and most of the common books in the Han Dynasty are bamboo scrolls, followed by silk silk, and the last is Caihou paper. Of the three types of paper, bamboo slips are the cheapest, but bamboo slips are not suitable for printing; This was followed by silk silk, and the price of silk was higher; The most expensive is Caihou paper, and Caihou paper is too crisp to be preserved.

Luan Yi paused and took a sip of the warm water handed by Cai Zhao. continued: "It can be seen that if it is a printing secretary, silk silk as a carrier is the best choice. So far, there is no other silk to replace it. Therefore, in order to produce the book, this expenditure must be consumed. As for engraving printing, Yi has a way to minimize the amount of money it consumes. ”

"Oh?" In fact, Cai Yong had inquired about carving books in the capital before, but the answer he got was that printing 10,000 silk books required 30,000 copper coins, and according to a set of books with 50 silk silks, the price of 10,000 sets was 150,000 yuan. In addition, Cai Yong also had a detailed understanding of the market, the reason why engraving and printing books is so expensive is because the cost of engraving accounts for the majority. The price of silk accounted for about one-tenth of the total, and the price of engraving accounted for seven-tenths. That is, in the price of 15 guan of a set of books, only 15,000 yuan (1 guan is equal to 1,000 yuan) is used to buy silk silk. And if this part of the price can be reduced with the increase of quantity. The price of engraving takes up 10 5,000 yuan, and the price of this part is diametrically opposed to silk, the more carved the more expensive.

With his Cai Yong's money and industry, even if he smashes the pot and sells iron, he can't make so much money!

Therefore, at this time, when he heard that Luan Yi had a way to reduce the cost of engraving, he immediately came to his senses and asked anxiously. "Will the plan be released?"

Luan Yi got up, wandering, and responded, "Carving insect Xiaojier." Yi named it movable type printing. ”

"Movable type printing?" Cai Yong and Cai Zhao exclaimed in unison.

"That's right, it's movable type printing." Then, Luan Yi explained the principle of movable type printing to Cai Yong and Cai Zhao in its original form. Tell them that movable type printing is the use of movable metal or clay blocks and the engraving of a single word on each block. This block engraved with a single word is the character mold. Speaking of which, the style of this glyph is very similar to the seal used on weekdays. After the character mold is made, the text is selected according to the content of the article, arranged in the word plate, fixed with pine resin, and then inked and printed. After the printing is completed, the font will be removed for the next printing. In this way, it is avoided to consume a large amount of stone slabs or unnecessary waste due to carving errors. Because of this, the cost of printing will inevitably drop significantly. Luan Yi said that according to his rough estimates, movable type printing can save at least half of the cost compared with engraving printing.

"Engraving? Movable type printing? Cai Yong, who had seen the world, immediately heard the preciousness of movable type printing from Luan Yi's words. If this can save half the cost, wouldn't it only cost 75,000 copies to print 10,000 sets of books? ”

"70,000 is enough!" Luan Yi smiled and nodded.

"70,000?" Cai Yong was ecstatic. But after a few breaths, he lowered his head again. Shamefully said: "70,000 is not a small number." The old man has been poor all his life, how can he get so much money! ”

"Huh? How? Cai Gong has to pay for the printing of books by himself? Obedient and listening, Luan Yi was shocked. He thought that Cai Yong was now the highest institution of learning in the Han Dynasty - the sacrificial wine of Taixue in the capital (his position was comparable to that of the president of Tsinghua University in the later generations), and this book was supported by Taixue! Now I know that the co-authoring of the old man is ready to pay out of his own pocket! Luan Yi sighed, originally he wanted to make a lot of money by contracting this government project! The price of 70,000 guan he quoted just now was actually added with water, and according to his estimates, he could win it at most 65,000 guan, and he would earn 5,000 guan for nothing. 5000 guan...... His four industries of Qifeng Pavilion, Mu Jinju, Home Inn and Yimufang add up to earn about 5,000 yuan a month!

"Wait......" In a moment of melancholy, Luan Yi's eyes suddenly lit up. Cai Yong shuddered at the startled words.

Recover from the panic. Cai Yong looked at Luan Yi expectantly and asked, "Can the virtuous nephew have a solution?" ”

"There is a solution." Luan Yi lowered his head and glanced at Cai Yong in front of him from the corner of his eye.

Cai Yong's lost heart suddenly ignited a few flames of hope. He said anxiously, "Come on." ”

"Cai Gong doesn't have any money, but he can borrow it from someone else!"

"Huh? The virtuous nephew is playing with the old man? The old man is not talented, and he has no friends who can borrow 70,000 yuan in vain. Besides, even if someone is willing to borrow 70,000 yuan from the old man, the old man will not be able to repay it. Cai Yong let out a long breath. The suspicious face suddenly drooped, and there was still a little anger in the vague way.

Luan Yiden was clear. Regardless of Cai Yong's lack of 70,000, he can't print books. Even if you have money to print it, the book will be printed for free! In this world, the rich people will not let 70,000 yuan go down the drain. "The ancient scholars, how rigid! Cai Yong is a scholar, but he is far from doing business! ”
