I watched Er Chuang’s short video, and everything went numb!

In the giant screen high in the sky.

Video refreshed again

【The Traveler's Book: Several necessary knowledge and skills. 】

This video title just appeared on the giant screen in the sky. Many emperors of the past dynasties immediately shouted orders to the civil servants who were responsible for recording:

"Record everything that people for future generations say next!"

"Don’t miss a word!"

The last title like this brought them very useful technologies such as home-made cement, sugar production, gunpowder granulation, mini bombs, and paper-cased fixed-loading ammunition.

Presumably, this time, it will also bring other very useful technologies. useful knowledge

【When you open your eyes and find that you are dressed in ancient Chinese costumes in an unknown place, then congratulations, you will most likely become one of the thousands of time-travelers.】

【Then, you are faced with a question: what to do next?】

【In other words, what would you do to survive in ancient times and survive better?】

【To this end, the UP owner has specially prepared several essential knowledge and skills for time travellers, for your reference.】

【Not much to say, let’s get straight to the point】

【First: Papermaking and Printing】

【These are two technologies, but because they are closely related, I will talk about them together.】

【It can be said that papermaking and printing are one of the greatest inventions in the world. Their greatness is that they broke the cultural monopoly, greatly reduced the difficulty of storing and disseminating knowledge and information, and even changed the hierarchical structure of human society.】

【With them, you will be able to cultivate talents in large quantities, and the power system will no longer be controlled by powerful families. With the popularization of knowledge, a new class will be born, and the dawn of industrial civilization will bloom in your hands, so I will It is listed as one of the essential basic knowledge and skills for time travellers.】

……

The plane of Emperor Taizong of the Tang Dynasty.

When he saw printing technology, Li Shimin couldn't help but look forward to it:

"Will the printing technology"Nine-Six-Seven" that will be introduced to future generations be movable type printing?"

He just learned about the existence of movable type printing from the previous video, and saw the admiration for movable type printing by later generations.

If future generations want to teach movable type printing, that would be great. Got it!

…………

【Let’s talk about papermaking first】

【As everyone knows, papermaking is one of the four great inventions of ancient China. During the Eastern Han Dynasty and the Han Dynasty, the eunuch Cai Lun improved papermaking technology and is considered the originator of modern papermaking.】

【Let’s draw an important point: Cai Lun improved papermaking, not invented it.】

【During the Western Han Dynasty, people already understood the basic methods of papermaking. An example of this is the Western Han Dynasty hemp paper unearthed at the Han Fengsui site in Luobunur in 1933.】

【However, the texture of this kind of paper is rough and inconvenient to use, so it is not enough to replace simple silk.】

【Therefore, if the dynasty you travel through is before the Eastern Han Dynasty and the Han Dynasty, you can use papermaking to become the foundation of your life.】

【Not to mention anything else, Cai Lun was named"Longtinghou" because of his great achievements in papermaking. If you come up with papermaking and dedicate it to the court, the emperor will have to make you a marquis.】

【After all, compared to bamboo slips, paper as a new writing material is really a revolutionary leap.】

【Before there was paper, the memorials approved by the emperor were written on"slips". Bundles of bamboo slips were pulled by eunuchs on carts, and several people carried them and placed them in front of the emperor's imperial desk. They were piled up into a hill. The emperor would read and review the papers on the desk every day. It was so tiring that his back ached.】

【With paper, the emperors' work will become much easier】

"Hahaha, I have to say that Brother Zheng is a workaholic. Historical records record that he has to read one hundred and twenty pounds of memorials every day, which makes him a unicorn."

"Dongfang Shuo once gave a memorial to Emperor Wu of the Han Dynasty with a total of 3,000 bamboo slips, which were carried in by two strong men."

"Before there was paper, reading was really inconvenient."

"……"

Along with narration and subtitles, as well as numerous barrages, a comparison picture of paper and bamboo slips appeared on the giant high-altitude screen.

The same content can be written on a thin piece of paper, but on the other side, it requires many thick bamboo slips.

……

Great Qin plane

"This paper is so thin and light, and so many words can be written on one piece of paper?"

Qin Shihuang looked at the paper in the giant screen in shock, his eyes full of desire.

He wants this thing!

This paper is much better than the bamboo slips!

If the ministers give him memorials, all of them will If he writes on this paper, he doesn't have to hold those thick bamboo slips every day.

Moreover, with paper, written records and knowledge dissemination will undoubtedly be more convenient, and it will also help to further strengthen the"book with the same text""

"Da Qin must make this paper!"

Qin Shihuang's eyes were extremely firm.

……

Not only in the Daqin plane, but also in the dynasties before the Eastern Han Dynasty and the Emperor plane, many emperors stared at the giant screen in the sky eagerly, wanting to know how this paper was made?

As long as he is not a complete fool, even if he is not a workaholic like Qin Shihuang, he still has to read a lot of memorials every day.

And the experience of looking at those thick bamboo slips all day is obviously not good.

【The basic principle of papermaking: Paper is composed of short fibers and binding materials (pulp or other materials). When combined together, they provide certain mechanical properties and void structure.】

【Theoretically, paper can be formed as long as fibrous tissues with a certain aspect ratio are bonded together.】

【Therefore, wood pulp, straw pulp, bamboo pulp, reed pulp, etc. can all be used as raw materials for paper making.】

【The performance of paper made from different raw materials will be more or less different. After you travel through time, you can try them all to find out the raw materials that are most suitable for the dynasty you traveled through.】

【Below, I will explain in detail the steps of making paper using bamboo as raw material.】

【1. Cut the bamboo into 1 meter long bamboo strips, add lime, and soak them in the pool for about 14 days.】

【2. Peel off the skin of the bamboo and clean it.】

【3. Beat until pulpy. If this step can be replaced by water or steam power, the efficiency will be much improved.】

【4. Steam the bamboo pulp and plant ash together for about 10 hours】

【5. Use running water to remove impurities from the bamboo pulp, add water and stir evenly to form a slurry.】

【6. Use a bamboo curtain (something similar to a mat) to swing the material in the wooden trough to become paper】

【7. After pressing the wooden board to squeeze out the water, stick it on the wall heated by firewood, let it dry and then it can become practical paper. 】

While the video was playing, various barrages were also flying out:

"The fibers in the pulp made from bamboo lack the necessary flexibility. Mixing the slurry of reeds into the slurry made from bamboo can improve the quality of the paper."

"The best adhesive is plant mucus, such as mucus leached from carambola vine, hollyhock, etc. After the Song Dynasty, this plant mucus replaced the previous starch paste."

"Using the fiber layer of paper mulberry as raw material is better than bamboo, and the paper quality is higher."

"……"

Da Qin plane.

Qin Shihuang said to Meng Yi in a deep voice:

"Meng Yi, I will leave the papermaking to you!"

"Papermaking must be successful within one month!"

"Obey! Please rest assured, Your Majesty, I will personally lead people to make paper and will never fail!"

Meng Yi said solemnly.

People in later generations have explained the steps so clearly. If he still can't succeed, he would be too incompetent.

……

In other dynasties before the Eastern Han Dynasty and the emperor's time, Liu Che and other emperors issued similar decrees to Qin Shihuang.

They were all determined to make paper.

Without any unnecessary description, the moment they saw the paper, they knew that as a writing material, paper was superior to bamboo slips.

It is not only the Eastern Han Dynasty and the previous dynasties before the Emperor's plane that will benefit from the content of this video.

In the Eastern Han Dynasty and the various dynasties after the Emperor's Plane, although papermaking was already available, it took a long time for a technology to emerge and be finally perfected.

Therefore, the ancients of these dynasties also obtained the direction of optimizing and perfecting papermaking technology at this time.

For example, before the Song Dynasty, plant mucilage could be used as an adhesive instead of starch paste.

Another example is that paper mulberry can be used instead of bamboo as raw material.

【After talking about papermaking, let’s look at movable type printing】

【The so-called movable type printing actually means to first make a single-character inverse character mold, then select the single characters according to the manuscript, arrange them in a type plate, apply ink and print, and then remove the character mold after printing, leaving it for the next printing. used again】

【It has four processes: first, making characters; second, selecting characters and typesetting; third, applying ink, laying paper, and printing; fourth, storing characters in an orderly manner.】

【We all know that movable type printing was invented by Bi Sheng, a civilian inventor, during the Qingli period of Emperor Renzong of the Song Dynasty. 】(To read exciting novels, go to Feilu Novel Network!)

【However, although movable type printing had been invented in the Northern Song Dynasty, movable type printing was not widely used in the Song Dynasty.Still block printing】

【On the contrary, after this technology was spread to Europe, it was improved by the European Gutenberg, which promoted the development of the European publishing industry and the modernization of Europe, and became popular all over the world.】

【The reason for this is that in addition to social factors, there is also a technical reason, that is, Bi Sheng invented clay type, and Gutenberg invented lead type, which is more durable than clay type and easier to apply ink.】

【So as a time traveler, when you introduced movable type printing, you naturally had to use lead movable type.】

【1. First use copper and iron to make the mold for the typeface, and then use an alloy of three metals with low melting points: lead, antimony, and tin to cast the typeface.】

【The approximate proportion is: the ratio is generally 11 to 23% antimony, 2 to 9% tin, and the balance is lead.】

【Tin was called white tin in ancient times, and lead was called green gold, black tin, Jin Gong, water gold, etc. As for antimony, the ancients called it Lian Xi.】

【Before the Qin Dynasty, these three materials had been used in ancient China, so it should not be difficult to find the materials.】

【2. Place the font model into the type plate for typesetting. The character plate can be an iron plate or a copper plate.】

【3. Apply ink. Movable type printing requires oil-based ink to function better】

【The production method of oil-based ink is as follows: Boil linseed oil, cool it, and use a small amount of distilled pine resin to obtain turpentine. Mix it with carbon black and leave it for several months to form a suitable black ink.】

【To prepare red ink, simply replace the carbon black with cinnabar, and the blueIt becomes azurite, and so on.】

……

The plane of Emperor Taizong of the Tang Dynasty.

Li Shimin’s eyes brightened[]

This movable type printing technology is truly extraordinary!

He is not completely ignorant of the current woodblock printing technology in the Tang Dynasty0....

Just engraving and engraving the characters takes a lot of time.

Moreover, once a typo occurs, it is particularly troublesome to correct it. Basically, a new version has to be carved.

But this was different with movable type printing.

They are all movable types one by one. If there are typos, you can change them at any time.

Moreover, after the typeface is produced, the typesetting can be flexibly typed according to different situations without having to engrave a new version every time.

This is much easier.

At this point, Li Shimin also understood why in the previous video, future generations would say that movable type printing would help the imperial examination system.

Because movable type printing will make the printing of books simpler, faster, and cheaper, thereby reducing the cost of books and making it easier for ordinary people to afford books.

Books are an important channel for the dissemination of knowledge. It is easier for ordinary people to obtain books, which means it is easier to obtain knowledge.

This will undoubtedly help break the intellectual monopoly of the world's elites.

The more Li Shimin thought about it, the more he felt that movable type printing was very useful.

"Pheasant slave, this movable type printing technology needs to be promoted in the Tang Dynasty. It is up to you to handle this matter."

Li Shimin said to Li Zhi

"Okay, Father. Li

Zhi replied in a deep voice.

Not only in the Tang Dynasty, but also in other dynasty planes, many ancients had a strong interest in movable type printing.

……

【MutuallyBlock printing and movable type printing have great advantages in large-scale printing】

【If you only print two or three copies, it is not easy. If you print hundreds or thousands of copies, the work efficiency will be extremely impressive. It will not only save a lot of manpower and material resources, but also greatly improve the speed and quality of printing.】

【Moreover, after the movable type plate is printed, it can be disassembled and the movable type can be reused. The movable type takes up less space than the engraving plate and is easy to store and keep.】

【I believe that with the movable type printing technology, after you travel through time, it will be easier to make money even if you become a bookseller.】

【Of course, if you have the conditions, you can also build a hand-operated printing press, which is a perfect match for movable type printing and can greatly improve printing efficiency. 】

On the high-altitude giant screen, a structural diagram of a hand-operated printing press appeared, with each component clearly marked.

The plane of the Great Ming Dynasty's ancestors.

Zhu Di said to Zhu Zhanji hastily:

"Draw it! Draw it!"

…………

【Second: Homemade Allicin and Homemade Penicillin】

【If you travel through time, no matter what the circumstances, medical knowledge must be one of the life-saving skills you must master.】

【Whether it is used to save yourself or to make a fortune, it is extremely useful.】

【Mastering the knowledge about the local preparation of allicin and penicillin, two broad-spectrum antibiotics, will make your journey through time go more smoothly.】

"Making a fortune through medical skills is a classic start for a time traveler in a novel."

"Reply - Indeed, I once read a novel that traveled through the Hongwu period of the Ming Dynasty. The protagonist came up with antibiotics and cured Zhu Biao's back carbuncle, and then he rose to prominence."

"Reply - That's absolutely true. If you can save Zhu Biao during the Hongwu period, both Lao Zhu and Zhu Biao will protect you and keep you rich and prosperous for the rest of your life."

"Reply - Xu Da also died from this disease. If antibiotics were produced through time travel, Xu Da could be saved, so Xu Da would not have to marry a daughter to repay his kindness? hey-hey"

"0.6 replies - But can back carbuncle really be cured with antibiotics?"

"Reply - Of course, back carbuncle was a very serious disease in ancient times. Nowadays, it is just a mild bacterial infection. With antibiotics, it can be easily solved."

"Reply - Indeed, as long as there are antibiotics, you will not die if you get back carbuncle"

"……"

The plane of Ming Taizu.

Zhu Yuanzhang looked at the giant screen in the sky and was shocked.

He finally knew the specific cause of Zhu Biao's death in the original history.

It turned out to be a back carbuncle.

In ancient China, many people, even if they were not doctors, had heard of this disease. the reason is simple.

So famous.

Because in ancient China, as long as the body had back gangrene, it was often difficult to cure, and it was basically sentenced to death. The"Huangdi Neijing Lingshu" once said:"The pus has formed, and you will die in ten years."

Before the Ming Dynasty, many famous people died of this disease.

"It turned out that I had back carbuncle."

A wry smile appeared on Zhu Biao's face.

No wonder he died in his prime.

There is no good treatment for back carbuncle. Even if he is a prince, he can only risk his life.

"Hey, that's not right."

Soon, Zhu Biao felt that there was something wrong with his thinking.

Since he knew in advance that he died of back carbuncle, he could just avoid getting this disease.

There is no need to worry about whether this disease is difficult to treat or not.

Just now At this time,

Zhu Yuanzhang said to Zhu Biao excitedly:

"Boss, you are saved!"

"You see, later generations say that as long as there are any antibiotics, back carbuncles can be cured!"

"Soon, future generations will teach us how to prepare antibiotics."

"Don't worry, if we have a method, we will definitely be able to get antibiotics out!"

Zhu Yuanzhang's tone was extremely firm.

No matter how much time it took and no matter how high the price was, he would still change Zhu Biao's fate of dying of illness in his prime.
