In the afternoon, Liu Yong went to the Prime Minister's Mansion to take leave to study medicine, Cao Cao bowed his head and agreed, and said: "Lonely Hua Tuo's medical skills are profound, and Chongru can summon him to the Prime Minister's Mansion tomorrow to treat the disease of head wind." Pen ~ fun ~ Pavilion www.biquge.info "Liu Yong was planning to open his mouth to seek medical treatment for Cao Chong, listening to Cao Cao's words, he couldn't ask for it, so he hurriedly agreed.

Cai Wenji said on the side: "Ming Gong, the slave family also wants to go with the son to see the divine doctor." ”

Cao Cao smiled: "Doctor Huashen will come to the house tomorrow, why should Sister Xian go again?" ”

Cai Wenji replied: "There is a peerless beauty in Liu Yong's mansion, and the slave family wants to meet her." ”

Cao Cao laughed and said, "Got it." Then you go with Liu Yong. He said to Liu Yong again: "You can follow Hua Tuo to study medicine, and the Prime Minister must come often, Zijian and Cangshu can not do without you." ”

On the way back, Liu Yong kept muttering on the horse, why did Cai Wenji go to see Diao Chan? Diao Chan's stepfather Wang Yun is Cai Wenji's father-killing enemy, shouldn't she go to Xingshi to ask for guilt?

Cai Wenji, who was in the car, saw Liu Yong frowning tightly and peeking at herself from time to time, so she beckoned him to come to her window and whispered: "Brother Liu wants to know why I want to see Diao Chan?" The two of them have been getting along for a long time, and they are usually extremely casual, when there is no one else, Cai Wenji calls him Brother Liu, and she gradually accepts and changes her name to "Wenji".

Liu Yong was stunned, but heard Cai Wenji continue: "Are you afraid that I will go to criticize Diao Chan?" ”

Liu Yong was even more surprised: "Are you the roundworm in my stomach?" You know what I think. ”

Cai Wenji took a sip and feigned anger: "You are the roundworm!" Suddenly, he smiled lightly and said, "Then do you want to know why I want to go?" ”

"Of course I do! Why are you going? ”

"Then you stick your ears out."

Liu Yong hurriedly bent down, put his ear to it, and only heard Cai Wenji whisper: "I won't tell you." Cai Wenji turned around, lightly covered her lips, and laughed with a "giggle", proud and happy.

Liu Yong had no choice but to shake his head and smile bitterly, it was really a reality report, it came so quickly.

At this time, Cai Wenji handed out a thread-bound book from the window, and said with a straight face: "Childe, this is what the prime minister entrusted me to bring to you." ”

Liu Yong saw that the words "Analects" were neatly written on the book, and gently flipped through the contents, and couldn't help but be surprised: "This is engraving printing." ”

"You know?" Unexpectedly, Cai Wenji was even more surprised.

"Where did this come from?"

"It is said that it came from Xiangyang. When Brother Liu was still in Luoyang, the prime minister invited a few craftsmen from Xiangyang to print the book. How do you know about engraving printing? Could it be that this is also your invention? ”

Liu Yong nodded lightly, there was no need to deny Cai Wenji, and asked eagerly: "Could it be that the prime minister also knows?" ”

Cai Wenji shook her head and said, "I don't know. Tomorrow you will personally ask the prime minister. ”

"So, Xu Du has already printed a large number of books?"

"yes. Brother Liu wants to go and see? ”

"Hmm. Let's take a look. ”

Asking questions along the way, the two soon found the location of the printed book. There were two soldiers guarding outside, and Liu Yong showed the waist card of the Prime Minister's Mansion and took Cai Wenji into the courtyard. It was a small courtyard with seven or eight craftsmen, one in charge and one in the bookkeeper.

The process of engraving printing is not complicated. First, choose wood with fine grain and solid texture, such as jujube wood, pear wood, etc. Then the wood is sawn into pieces of planks, the characters to be printed are written on thin paper, and the carver uses different forms of carving knives to carve the reverse characters on the woodblock into raised yang characters, and at the same time the remaining blank parts on the woodblock are removed to make it concave. The characters engraved on the board surface are about 1~2 mm on the convex surface. Rinse the carved board with hot water, wash off the wood chips, etc., and the engraving process is complete. When printing the book, use a cylindrical flat-bottomed brush dipped in ink, evenly brush on the board, and then carefully cover the paper on the board, and take a clean brush to gently brush the back of the paper, and the paper will print a positive image of the text or picture. The paper is lifted from the printing plate, dried, and the printing process is complete. After the pages are printed, they are bound into a book, and a book is made.

Liu Yong asked the person in charge, "Where did you learn these skills?" ”

Seeing that it was someone from the Prime Minister's Mansion, the person in charge did not dare to slack off, and replied respectfully: "In Xiaxiangyang, this skill was stolen from Fuyi County. ”

Liu Yong nodded secretly, and asked again: "How many copies can be printed in one plate?" How much can be printed per day? ”

Seeing that Liu Yong was asking very professionally, the steward was even more impressed, and said: "A plate can probably print about 10,000 copies, as for the number of prints per day, because my craftsmen are not very skilled, they can only print about 1,000 copies." It is said that craftsmen in Fugui County can print 2,000 sheets a day. ”

Liu Yong nodded again, and then asked, "Do you think it's good to print like this?" ”

Seeing that Liu Yong was an expert, the steward replied seriously: "Books with great demand, such as the 'Four Books and Five Classics', are extremely convenient to print by this method, and I think that this technique will be implemented throughout the country." Liu Yong deeply agreed that the papermaking and printing technology invented by the Chinese have provided the most convenient conditions for cultural transmission and civilization exchanges, and have made irreplaceable contributions to the development of the world.

"Did you encounter any difficulties?" Liu Yong asked again.

"Don't hide it from the son, it's not easy to make plates. Childe, please look at ......," the steward said, pointing to an engraving plate, "There are dozens of characters on one plate, and there are several strokes in each word. If you are a little careless, the knife is deflected, and it is broken, and it becomes a waste version, so you have to start again, which is a pity. ”

Liu Yong said: "This is indeed the disadvantage of engraving printing. Anything else? ”

The steward pointed to the next few large houses and said, "After the engraving is printed, it is useless, so it can only be piled up here." It's fine if you print it again in the future, but it's a pity if you don't print it again. After a year and a half, I can only split to burn the fire. ”

"Why don't you keep it all the time? Wouldn't it just take some space? ”

"Childe doesn't know anything. These are all made of wood, and in summer and autumn, there are disadvantages of cracking. And insect and rat bites, it is not easy to preserve. ”

"I see. Thanks steward, you can get busy. The steward gave up his hand and did not mention it.

"It turns out that the truth is so simple, it's the same as a seal, why hasn't anyone thought of it before." Cai Wenji carefully observed each process before coming back, and with a burst of emotion in her mouth, she said to Liu Yong: "How did Brother Liu think of it?" ”

Liu Yong smiled: "You want to know? ”

"yes!"

"Then you tell me why you want to see Diao Chan first, and I'll tell you."

"Phew! Don't. ”

As soon as Liu Yong arrived at the gate of the mansion, the steward of the Prime Minister's Mansion was already standing there, and he first bowed his hand to Liu Yong and said, "General Liu." He said to Cai Wenji again: "Miss, the prime minister instructed that an old friend of Mr. Bo Ji came from Chang'an, please return home immediately." Cai Wenji was stunned for a moment and sighed: "It seems that I can only go to see Sister Diao Chan in the future." ”

The next day, Hua Tuo first went to the back hall to diagnose a few sons, and Cai Wenji excitedly told Cao Cao about the method of printing books he saw yesterday.

"Oh. Chongrulai tell me how it was printed?"

Liu Yong was stunned for a moment, peeking at Cai Wenji, only to see that she secretly waved her hand to herself, signaling that she had not told Cao Cao, so she fixed her mind and said: "Prime Minister, you should ask the printer about this, why did you think of asking Liu Yong?" ”

Cao Cao laughed and said: "Chongru, Chongru, don't you really know if you are lonely? What you have done, the old man has specially sent someone to investigate, porcelain, winemaking, engraving...... Which one is not relevant to you. ”

Liu Yong was dumbfounded, looking at Cao Cao's smug face, knowing that he couldn't hide it, so he had to say: "Prime Minister, Liu Yong is low-key, not deliberately deceiving." ”

Cao Cao said with a smile: "Chongru, you can't be too arrogant, and you can't be too restrained. If Mao Sui is like you, if he doesn't recommend himself, how can he impress the king of Pingyuan and send an envoy to the state of Chu, and how can he persuade the king of Chu to relieve the siege of Handan? ”

Liu Yong arched his hand and said: "Thank you Prime Minister for your teachings, Liu Yong wrote it down." ”

Cao Cao smiled again: "It is said that Fuyi was originally a remote county, and in just two years, it was comparable to Jiangxia, and Chongru has made great contributions. This phase has been written on the saint, and Fuyi County is promoted to Ruoyuan County, Ren Chongru is the Taishou, and Yu is the county. ”

Liu Yong was taken aback, Cao Cao was using a high-ranking official to appease me, but he said with a happy look on his face: "Thank you, Prime Minister." ”

Cao Cao smiled: "First Mo Xie, how did you come up with this engraving and haven't told the old man yet?" ”

Liu Yong explained the principles one by one, and Cao Cao nodded as he listened. At this time, Xun Yu said on the side: "Prime Minister, now our army is confronting Yuan Shao, since engraving printing is so fast and convenient, why don't you print the "Art of War" annotated by Prime Minister and the new book of war, and distribute it to various departments as a marching guide?" The other advisers agreed.

Cao Cao was also proud in his heart when he heard this, and said with a smile: "According to what the princes said, it's just that this book has just been written, what should be the name?" Liu Yong was still in a dream at this time, only to feel that someone gently pulled his sleeve, turned his head to see, it was Cai Wenji, only to hear her say in a low voice: "I didn't expect that Brother Liu has so much ability to hide from my little sister, but I have to know, don't hide it anymore." ”

Liu Yong had to smile bitterly and nodded, and listened to Cheng Yu say: "This book is written by the prime minister to consider the past and the present, painstakingly and painstakingly, imitating the thirteen articles of "Sun Tzu", in my opinion, how about calling it "Mengde's New Book"?" ”

"Mengde's New Book, good, this name is good!" Everyone agreed.

"It's a pity that time is pressing, and there are few carvers in the city, how can we engrave and print in the short term?" Xun You said worriedly.

Hearing the name "Mengde's New Book", Liu Yong's heart was shocked, this "Mengde's New Book" is Cao Cao's summary of half of his military career, refining and innovating on the basis of his predecessors, a total of 14 articles, of which 13 are the art of war, and the last one is political strategy. According to the evaluation of the Tang Dynasty's "Tang Li Asks the Right Questions", this book has created a new peak in China's military theory of war. It's a pity that it was lost in the end, and of course it was not as described in "Romance of the Three Kingdoms" Zhang Song ridiculed that this book was written by Cao Cao stealing the achievements of his predecessors, and Cao Cao burned it in anger.

Four words popped up in Liu Yong's mind, "movable type printing". The principle is actually not complicated, but time is pressing, whether it is wood type or clay type, it is too late, what should I do? Liu Yong's mind was racing, and he suddenly remembered something, and couldn't help but cry out softly with an "ah".

"What did Chongru think?" Cao Cao asked.

Liu Yong bowed and replied: "Prime Minister, I have thought of a recipe in the future, and I may be able to print it soon." ”

Cao Cao was overjoyed and said, "Can Chongru complete it in three months?" ”

Liu Yong said: "If there is a warrant from the prime minister, it will only take two months." ”

Cao Cao was surprised and delighted: "If Chongru can be printed in February, this picture will be rewarded." (To be continued.) )
