In the early morning, everything is silent, the sun on the eastern horizon secretly flashes a trace of bright light, carefully invading the light blue sky, indicating that a new day is gradually coming, gradually, gradually the whole world is brightened, the sun through the light mist, gently sprinkled on all things, there is a surprising and pleasing feeling, people suddenly feel calm, relaxed. On Jungnam Mountain, on the buds that are about to bloom, the crystal bright dew drops shimmer with a delightful light, and they look vibrant.

On the top of the mountain, Li Xuan and Zhao Meng were leading a small number of students who were burning mud, and other students who were reading early also put down their textbooks and looked at the busy Li Xuan and his party in surprise.

Li Xuan, Zhao Meng and others are now making the cement into a blank with the same specifications, and then engrave the reverse list at one end of the blank, and the height of the protrusion of the character is like the thickness of the edge of the copper coin, and now it is being hardened with fire to become a single cement movable type.

Su Dingfang, who looked confused, slowly walked in front of Li Xuan and asked respectfully, "Teacher, what are you doing here?" What is the use of this burnt mud? ”

Su Dingfang asked the questions in the hearts of the other students, and all the students also looked at the busy and focused Li Xuan with doubts on their faces.

Li Xuan smiled and didn't answer, but picked up a piece of burnt clay, used a small brush to evenly brush the bottom of the clay, brushed a thin layer of ink, and then printed the clay on a piece of paper with a little force, and suddenly on the white paper, a clear Chinese character suddenly appeared.

Su Dingfang was puzzled: "Teacher, are these burnt muds all seals?" ”

Seal, Su Dingfang has seen it. Nowadays, in the Tang Dynasty, everyone has their own official seal, and of course many people also have their own private seal. It's just that the seal made of mud is the first time Su Dingfang has seen it. Su Dingfang couldn't figure it out. Since his mentor Li Xuan likes seals, why doesn't he use good jade like everyone else, but uses mud instead? Could it be that the teacher is made of mud in order to popularize seals and let every Tang people have their own private seals? Su Dingfang thought about it and felt that it was wrong, not to mention that the seal made of mud was not durable, even if all the people of the Tang Dynasty had the seal, what was the use? Su Dingfang couldn't figure it out, and neither did all the students on Zhongnan Mountain.

Li Xuan, on the other hand, unhurriedly took out the book "Analects" and asked the students to follow the content of the first ten chapters of the "Analects". The clay movable type is typeset, then the ink is evenly smeared with a brush on the reverse text below the clay tablet, and finally the clay tablet is gently pressed on the white paper, and the content of the first ten chapters of the "Analects" of the whole page suddenly appears clearly on the paper.

All the students looked at the scene in front of them in amazement, they didn't dare to imagine that the seal could be used like this.

Li Xuan ignored the student's surprise, but continued to use a brush to evenly smear the ink on the reverse text under the clay tablet, and then press it on the paper, repeating this more than ten times. The contents of the first ten chapters of the Analects appear clearly on more than a dozen sheets of paper.

It was only at this point that all the students understood the important role of these burnt clays: with only a few copies of these clay tablets, the entire Analects would be printed without limit, so that everyone in the whole world could own the Analects. Learn the ways of the saints.

Such a result made all the students gasp. Everyone knows that these burned mud will have a significant and far-reaching impact on Datang. As everyone knows. The way of the saint is not something that everyone can learn, and all kinds of books are monopolized by the major wealthy families, if you want to learn it. must be a child of a wealthy family or a descendant of a wealthy family, which is also the main reason why a wealthy family has survived for thousands of years. Because of the preciousness of books, others have no chance to watch and learn, let alone memorize and figure it out. Therefore, for thousands of years, the whole world has formed such a cycle: to be an official, one must be familiar with the words of the sage, and if you want to get in touch with the doctrine of the sage, you must join the wealthy family and become a descendant or successor of the wealthy family. People are not born to understand the truth of the sage, nor do they understand the truth of governing the country without studying, so the result is that the whole world, all the officials are from the major wealthy families. Shandong Hao clan is because they are all Confucius, Mencius or their disciples' descendants, with the most orthodox and comprehensive sage books, above the court, among the officials and scholars, they occupy the highest proportion, reaching today's seventy percent. Since the officials are all from the major wealthy families, when formulating national policies, the interests of the major wealthy families where the officials belong are often considered first, and then the interests of the entire country. Therefore, the power of the world is in the hands of the major wealthy families, and even if he becomes the supreme emperor, His Majesty is born between the forces of the major wealthy families. There is no cold man in the top grade, which is also a very common phenomenon and consensus in the whole world. And if these clay tablets fired by Li Xuan can be popular in the world, then the sage doctrine, everyone in the Tang Dynasty can learn, and no longer need to worship under the major giants, the world's officials, the world's readers, will completely get rid of the dependence on the major giants, and the major giants will also lose their monopoly on books and knowledge, and their strength will be greatly weakened, which will be a major change for the original situation of the whole world.

Li Xuan did not pay attention to the students who were all contemplative, but rearranged the clay tablets according to the content of the first five chapters of the "Book of Shang". After that, he used a brush to evenly apply ink to the reverse text at the bottom of the clay tablet, and gently pressed it on the paper, and so on, and the content of the first five chapters of the "Book of Shang" was clearly presented on dozens of white papers.

Seeing this scene, all the students frowned even tighter. By adjusting the order of each clay tablet, new content can be printed. It's amazing, it's unbelievable. The students were not only surprised by the magic of these clay tablets, but also troubled by the impact of these clay tablets on the pattern of the world.

The technique used by Li Xuan to burn clay tablets one by one and print characters is what later generations called one of China's four great inventions -- movable type printing. Nowadays, among the four major inventions, papermaking and the compass have already been invented, and the invention of movable type printing will have epoch-making significance for the situation that knowledge and books are monopolized by major wealthy families. If the government before the Tang Dynasty was controlled by the emperor and the major wealthy families, then with the emergence of movable type printing, more books were printed by the printing plate, and there were more commoner children, so there was an opportunity to contact knowledge and power, and more and more civilians began to gradually move towards the court, gradually control the power, and finally formed the emperor and all classes of scholars, elites of all classes, jointly control the situation of power, which led to the gradual perfection of the entire feudal society and the peak. It is more suitable for the development of the whole society and stimulates the vitality of the whole society.

The advent of movable type printing made the two thousand students of Zhongnanshan fall into contemplation, and everyone fell into deep worry. The 2,000 students are all from the major wealthy families, and they are deeply aware of the deep threat of movable type printing to the power of the major wealthy families. (To be continued......)
