Printing originated from Taoist engraving printing, active in the Sui Dynasty, developed and perfected by Bi Sheng in the era of Song Renzong, produced movable type printing, and was transmitted to Europe by the Mongols, so later generations called Bi Sheng the ancestor of printing.

Nowadays, Datang Paper's technology is developing rapidly, which is a good opportunity to carry out printing on a large scale. Therefore, Li Yi told Lu Su about the technical concept of movable type printing.

"Ahh A single word, a combination of frames! Lu Su was shocked, this seems simple, but it contains a great truth. There are more people engaged in printing, and no one thought of it, but it was thought of by the emperor: "The emperor is shengming!" ”

Li Yi often pirates, his face is thick, he smiled modestly, and said in his heart that the master is not holy, and he is just standing on the head of the saint. So he said, "Take the edict and go." ”

Lu Su retired, whipped his horse, and went to find Shen Kuo and Ma Jun.

………………

Northwest suburb of Jicheng, Datang Academy of Sciences.

There are all kinds of skilled craftsmen in Datang here, and there are even "weirdos" who specialize in various natural disciplines. These people, if you are in modern times, are chemists, physicists, and so on. And because in ancient times, Confucian reading and learning characters, governing the country, and chanting poetry were the right way, so these people were called "weirdos".

However, Emperor Wude Li Yi liked these "weirdos" very much, and these weirdos must be the originators of modern science in the future. There are always people who like to study nature, so Li Yi recruited the best of them and enthusiasts into the Academy of Sciences, and if they continue to study from generation to generation, they will definitely be able to reap rich results.

On this day, Lu Su, Shen Kuo, and Ma Jun surrounded two drawings, one large and one small. Small, similar to the banknotes of later generations. The large one resembles the silver ticket of the later generations. One big and one small, the painting is delicate, and there are shrewd patterns. Don't underestimate these patterns, they are very regular. Seiko craftsmen are dizzy when they see it, and only the top craftsmen can carve it out.

"Big or small?" Ma Jun asked.

Shen Kuo touched his beard and said, "Even if the big carving is particularly difficult, it is relatively easy to carve the small one. ”

Lu Su said according to his businessman's eyes: "The big one is not easy to carry, and it needs to be folded." If you fold it more often, it will be easily damaged. ”

"That's small." The trio made a decision.

Lu Su thought about it for a while, and added: "Can the difficulty be increased a little more, it is best to carve the seal like silk." In addition, this silver ticket was invented by the emperor, and your seal engraving is not very good. If the emperor is a hundred years later, how to carve the seal? After thousands of generations, who will remember the emperor's exploits? ”

"Yes, yes...... What Zijing said is very true. Ma Jun wiped his sweat, and said in his heart that this was negligence, how could the emperor's thousand-year-old exploits be erased?

Shen Kuo nodded heavily and said, "What Zijing said is too good, we must think of a way to reflect it on this silver ticket." Thousands of years later, when people see the silver ticket, they can think of the emperor and the emperor's great achievements...... It's just that later, there must be the era name of the latecomer of the Tang Dynasty, so how can people thousands of years later think of our emperor when they see the silver ticket? ”

………………

The Imperial Study.

When Li Yi got Lu Su's report, he suddenly stood up from the dragon chair and exclaimed, "What! Print my avatar on the banknote?! ”

This treatment, which only a great leader has, now came to his head and shocked him.

"Yes!" Lu Su looked at Li Yi with admiration and said, "The emperor has created a great cause for thousands of years, and the world cannot forget the emperor's achievements." In addition, with the portrait of a top painter, the seal of the top master is carved into a template, so that the double insurance must not be forged. ”

Banknotes are most afraid of counterfeiting, the works of ancient painters, that is, in later generations, high-tech can not do ten percent of the simulation, plus the master of the seal carving, this insurance is absolutely in place.

However, Li Yi waved his hand again and again and said: "No, no, no, only truly great people can be passed down through the ages." I have some achievements, but not enough. ”

Lu Su hurriedly said: "The emperor begged for the Yellow Turban, conquered the north, swept the Central Plains, collected Bashu, swept the Nanban, Pingjiangnan, collected Dongying, Tianzhu, Guishuang, and rested. The Qin and Han dynasties are thousands of miles, and the Tang Dynasty is more than 100,000 miles. Such an achievement, even if the three emperors and five emperors are combined, they cannot be compared. How can it be said that there is no merit? If such a merit of the emperor cannot be passed down through the ages, who can pass on the merits of others? ”

"Your Majesty, if you don't agree, the world will be sad."

"This ......" Li Yi touched his nose and said in his heart, does the master have such great merits? It seems that there is a ......

Li Yi couldn't help but smile, but quickly took it back, and said helplessly: "In this case, let's do what Aiqing wants!" ”

"Yes!" Lu Su left overjoyed.

………………

Five days later, the Datang Academy of Sciences.

Lu Su, Shen Kuo, and Ma Jun gathered around a large offering table, looking at several prototypes of banknotes of different denominations with admiration.

I saw that on this banknote, there are Chinese characters and minority characters, as well as multiple coats of arms representing the Chinese ethnic groups. There are the original "numbers" of Emperor Wude, and the denomination of capital Chinese characters, and naturally the hairstyle and year name are indispensable. These are all on the four outer edges.

On both sides, there are halls of the Forbidden City that represent the power center of the Tang Dynasty. One article to one hundred texts, consistent denomination, five runs, ten runs of denominations until a hundred runs of large amounts, in turn is the Temple of Heaven, Qianqing Palace, Baohe Palace, Taihe Hall and so on. Without exception, in the middle of these magnificent buildings is the portrait of Li Yi, the founding emperor of the Tang Dynasty and the Wude Emperor.

This portrait is painted vividly, lifelike, the hair can be counted clearly, and the golden dragon pattern on the neckline is stepping on auspicious clouds. On the other hand, the national emblem and national flag of Datang are all there.

"That's it, it's exciting to watch!" Lu Su slapped the board.

So, on the one hand, the three of them found a master craftsman and began to engrave the banknote template, and on the other hand, they looked for the paper of the banknote. In the end, it was decided to use a special paper "mulberry paper" of Datang as the carrier.

The mulberry paper is pale yellow, and the obvious fiber structure can be seen in the mulberry paper with exquisite craftsmanship. The local government classics and books formed during the Ming and Qing dynasties and the Republic of China are basically mulberry paper as pages, and the appearance and feel are beautiful.

The thousand-year-old mulberry paper is known as the living fossil of the human paper industry. For thousands of years, it has recorded China's traditional papermaking technology and is a window for people to understand the history of paper culture.

After Li Yi crossed this time and space, later generations recorded that mulberry paper was also called "Tang paper" in ancient times. It originated during the Tang Empire. It is made of mulberry bark and is mainly produced in the Central Plains of the Tang Dynasty.

According to relevant historical records: as early as the Tang Dynasty, the Yangzhou area produced leather paper, which has a history of 1800 years. The paper is named after the era and is called Datang paper.

Li Yi mobilized 9981 top carving masters, each of whom was responsible for a part of the pattern. Shen Kuo, the secretary of the Ministry of Industry, personally operated it, and his technique was even more unique, specializing in secret notes, and produced an article...... Consistent, ten-、...... To the banknote template of the hundred.

After that, Li Yi issued an edict, and 9981 masters made great achievements in making templates, gave them the title of lord, and rewarded the ladies of the mansion with countless money, and let them retire early and go home to live in their old age. Guards were on guard all day, and Shadow Guards were watching. Until these masters died, no one was able to make the exact same template. And after people get used to it, they can distinguish the true from the fake with a little identification.

………………

At the beginning of May of the 11th year of Tang Wude, the Great Dynasty Meeting.

Before Li Yi came, the ministers led by Xu Maogong began to talk about it.

"If the emperor insists on going his own way and wants to use paper money as the currency for transactions, we will die!"

"Yes, death!"

……

The ministers were indignant, and they couldn't bear to use crude paper money as currency. You can use gold and silver nuggets. Even the ministers of military aircraft in the Military Aircraft Department could not understand it.

Of course, the ministers of military aircraft did not take the liberty to participate, what they thought more about was that this paper money spent in vain was too easy to counterfeit, and this was not a clear push of the Datang economy into the fire pit.

The economy of Rome has not collapsed here, and the economy of the Tang Dynasty is about to be collapsed by the emperor's whims.

Yue Fei and Xu Da, the generals who led the troops, did not consider these cumbersome government affairs, they only considered one thing, when the emperor said who to fight, how to fight who would be beaten more badly, and the fight was in line with the emperor's mind.

"The emperor has arrived!"

With the cheers of the female officials on duty, solemn music sounded, and Li Yi came to the court wearing a bright yellow dragon robe.

He sat down here, under the dragon platform, in the main hall, the civil and military three shouted long live: "Long live my emperor, long live, long live." ”

Li Yi held his hands and said loudly: "Zhongqing is flat." ”

"Long live thanks."

The generals here stood up one by one, and none of the civil officials on the opposite side stood up, all of them were blushing and thick-necked.

"What do you mean?" Li Yi muttered in his heart, "Who is this fighting with?" ”

Seeing the first person in Confucianism, Yansheng Gong Kong Rong climbed out first, hugged the courtboard, looked up, and said with an agitated face: "Your Majesty, do you still want to insist on issuing paper money?" ”

Li Yi frowned, and said in his heart, okay, this is a fight with me!

Unhappy in his heart, Li Yi said with a dark face: "It's not paper money, it's different from the paper burning money." This is money, for the living. ”

"Paper money for living people, this is even more amazing!" Kong Rong shuddered for a while and said, "The emperor let the living also use paper money, which reverses yin and yang, what kind of system." If the emperor insists on using this national policy, the minister would rather die......"

"The minister is willing to die!"

……

With Kong Rong taking the lead, Wenchen was excited, and they all hugged the court board and asked to die.

The military general was immediately dumbfounded, and said in his heart that these scholars are nervous? This banknote is a good national policy, and you don't have to go to the street with a big wooden box to buy things in the future, isn't it very good.

Wenchen danced with his hands, and the ministers of the Military Aircraft Department hung their heads and did not speak.

Li Yi's face trembled, and his heart said that you are all dead, and I am the first faint monarch in the world, and you are all famous ministers in history!

There are no doors! Li Yi waved his hand and shouted angrily: "If you want to die, wait a while and then die, kneel down first!" ”
