On the fifth day of the third month of the sixth year of Jianji, spring sowing has ended.

After the dynasty was dispersed, Shao Shude looked at the contents of the "group".

The commander of the Xingzhou camp, Lu Huaizhong, briefly reported the battlefield situation and requested a new batch of equipment, including arrows, wounded medicine, rain cloth, etc.

All the troops had gathered at the city of Zhenzhou. After ten days of fierce attack, they began to dig trenches and besiege.

The appearance of the Wansheng Huangtou Army on the battlefield caused chaos in the army. A high-ranking general wanted to surrender, but was killed by ordinary soldiers, and all his wealth was taken away.

In Lu Huaizhong's official letter, all the envoys and ministers of the Privy Council had already commented. Shao Shude looked at it and wrote a big word "公" and forwarded it to the Political Affairs Hall, and he urged the Ministry of Revenue to allocate materials.

After finishing his work, he called Zhou Zhizhong, a medical officer of the Imperial Medical Office.

Zhou Zhizhong is also an old man. He was the consul of Zhou Silang, a medical officer in Lingzhou. He has been a doctor for nearly twenty years and has rich experience. He is now one of the four medical supervisors in the Imperial Medical Department (from the eighth rank).

"I will count customs and diseases in various Daozhou, so busy that I can't touch the ground. How can I do what I taught you?" Shao Shude asked.

Chu gave birth to a daughter in October last year. She died of illness two days ago. The imperial physician was helpless. Shao Shude said it was a bacterial or virus infection, and the imperial physician was at a loss.

He couldn't explain either.

According to the rules of seeking truth from facts, things you cannot prove are not science, but hypothesis. If you want to convince others and let others accept your views, you cannot rely on your own power and influence, but on practical scientific basis.

This is the point he has always instilled and he will not blatantly destroy it.

In fact, he had told Zhou Shilang many years ago that the viewpoint of bacteria and viruses was discussed with Zhou Shilang, but no one believed it. He could not lock himself in the house like Levinhoek, and spent many years to manually polish various high-magnification magnifying glasses and then assemble a microscope. What's more, he didn't even know how to polish the lens.

Fortunately, there are craftsmen.

The emergence of lenses is very early. The earliest physical lens unearthed in the world should be a crystal lens that can magnify objects created by the Assyrian Empire, the successor of the ancient Babylonian civilization, on the eve of its demise (more than 700 BC).

An exquisitely crafted crystal stone lens with gold ornaments was unearthed from the tomb of Liu Jing, the King of Guangling of the Eastern Han Dynasty. It should be a magnifying object for the nobles to play with.

But at this time, Shao Shude searched for a long time before he found a former Tang Shaofu craftsman who was hiding from the war in Jingzhao Prefecture County. He knew how to make lenses.

This made him ponder why this technology was not promoted, so that it was almost lost? Could it be invented again hundreds of years later? The conclusion is that without a market, there would not be too many people to use it. At best, it was just a magical trick or trick in the hands of royal families and nobles, and of course it was easy to lose it.

Without a broad market technology, it is destined to be without vitality.

The craftsman was hired by a large sum of money and went to the Youshang Office of Shaofu to work as a supervisor from the ninth rank. He brought more than a dozen apprentices and began to polish the lens.

Their first task was to cooperate with the Imperial Medical Department to polish the lens, then enlarge the object, and try to discover what Shao Shude said about the bacteria.

"Your Majesty, there is no progress yet. Master Mani said that there are also great foods in this kind of thing, called the 'reading stone'. After hearing this, the Secretariat asked for a few more. The Secretariat of Song and Secretariat of Chen were very fond of it, and asked the Young Mansion to do more." Zhou Zhizhong replied.

Shao Shude nodded, picked up a bound book from the desk, called the palace servant to hand it to Zhou Zhizhong, and said, "This is a big food manuscript compiled by the Imperial College. Let's take a look, and then listen to the craftsmen, and you may gain something. In addition, you may need two lenses to add up... Forget it, I will let the Ministry of Internal Affairs do this."

Zhou Zhizhong took the manuscript and saw that there were only three words on the cover: "Book of Light", which is inappropriate.

Of course, Shao Shude felt the same, just translated the manuscript, that's it.

He had read this book, and the knowledge points were messy and had not been effectively connected. But he felt that after studying Dashi for dozens or hundreds of years, he might be able to perfect theories into a book.

In 1015, Arab scholar Ibn Hessim published the epoch-making optical book "Book of Light" after systematically studying the locally circulated ancient Greek optical knowledge.

This book corrects some wrong perceptions in ancient Greece. For example, Hessim believes that people can see objects because the light on the object is reflected into the human eyes, while the Greeks believe that people's eyes emit light and touch objects, so they can see them.

This book also mentions the working principle of lenses (including convex lenses and concave lenses) and the simple magnifying glass production.

This knowledge was not passed on to the East, but it communicated with the West. After absorbing and digesting it, Europeans made the world's first microscope five hundred years later, which was made by glasses vendors. At that time, China was in the middle of the Ming Dynasty, and had insufficient communication with the outside world and gradually began to lag behind.

After reading this book, Shao Shude sighed in his heart. Hessim was able to write this book because he stood on the shoulders of a giant. Before him, the corresponding knowledge had been done a lot of research and proposed many theories. He finally sorted out, improved, errata, and wrote works.

"Go back and see slowly." Shao Shude waved his hand and said, "The Tang Dynasty is magnificent and colorful, with a prosperous culture, attracting all countries to come to the court. The Great Xia will not be worse than the Tang Dynasty. But I don't want you to be too arrogant and arrogant. The world is very big, and even a small country has its advantages. Seeking truth from facts, we just need to learn the good things of others. We don't know if we don't read this manuscript. I was shocked to see that the great cannibals have studied so deeply. They may not be as good as China in some aspects, but they have made it better in some aspects. Avoid being arrogant and the Middle Land is vast. Although the land is vast, the people are not much worse. Just like that."

"Yes. I'm leaving." Zhou Zhizhong held the book and slowly retreated.

Shao Shude tapped the table again and said after a long time, "I sent an order to run the school in the Ministry of Internal Affairs."

This idea has actually existed for a long time. While the court has now allocated funds to the Ministry of Internal Affairs, we should do it quickly.

This school is not just an educational institution, but more precisely, an industry-university-research institution.

Technology must have a market and be deeply promoted. This bloody and tears have taught the Chinese people how many times they have eaten it from ancient times to the present.

The waterwheels from the Sui Dynasty were reinvented in the Ming Dynasty, which is simply funny!

Taking optics as an example, the market actually exists.

There are countless old officials, nobles and wealthy businessmen with dizzy eyes. For them, glasses are a necessity. In history, Italians invented glasses. In the middle of the Ming Dynasty, they were introduced to China through Southeast Asia, and glasses shops appeared in Suzhou, which proved that the demand was quite large.

But what needs to be solved urgently is actually the cost issue.

A new technology is too expensive and is still not suitable for promotion, so there is no market and will eventually disappear.

Cost, this is something that is easily overlooked.

Some people subconsciously believe that as long as something is made, it will definitely be promoted.

Manufacturing cost, service life, work reliability, promotion channels, after-sales maintenance, etc., are all very important, and they all determine the fate of new technologies and new products, and determine whether they will gradually disappear in our lives after they are invented and reinvented hundreds of years later.

Glasses made of crystals will not be low in cost, and will only be passed down to the wealthy class, unless there is glass - it must be cheap glass produced on a large scale, and expensive glass is no different from crystal.

However, for now, relying on the rich market alone seems to ensure that glasses will not disappear. After all, Europeans did not have glass at the beginning.

First, slowly maintain the optical market and expand the number of employees as much as possible. With more people, the technology can be maintained and even further developed - the number of employees is very critical. Theoretically, the more people in this industry, the easier it is to pass on the technology.

Shao Shude promotes new things and tries not to use administrative orders, government investment, and forced implementation, but to naturally spawn industries through market orientation and market demand.

The routine of the optical market is essentially no different from wool.

Of course, behind the business, he cares more about maintaining cultural and technological connections with the West (Central Asia, West Asia, Europe).

Working behind closed doors is a dead end and will gradually lag behind foreign countries. In the middle of the Ming Dynasty, facing the endless emergence of new knowledge and new technologies in the West, lack of communication and knowledge, gradually being widened by people. By the end of the Ming Dynasty, the gap had been astonishingly large.

From this perspective, Shao Shude felt that the importance of the Western Regions had risen by several levels.

Central Asia and West Asia are a major agricultural and commercial country. In fact, they are quite prosperous in culture, with many innovative things and their own unique skills. The Tubo people rely on the smelting technology obtained from Central Asia and the troops they manufacture are not inferior to the Tang Dynasty, and those countries are actually not behind.

If there were no natural disasters of destruction brought by the Mongols, which seriously regressed the civilizations of Central and Western Asian countries, history might be another direction.

Shao Shude felt that it was necessary to maintain the existence of these countries, communicate with the Central Plains, and communicate with each other. Everyone learns together, promotes each other, and progresses each other, so that they can look east and go east, at least maintain a balance in exchanges with Europe and China, and not focus on one side. Perhaps it is a great thing that can change the future of the entire nation.

There are only a limited number of things that time travelers can do. When there are millions of civilized people in the West who have not been destroyed by barbaric Mongolia to do research and study, and then communicate with the East, the benefits to social civilization progress may be greater than that of a hundred time travelers.

Thinking of this, he couldn't sit still anymore and deeply felt that there was not much time.

"Chu Shenping!" Shao Shude shouted.

"I am here." Chu Shen put on his helmet and armor and entered from the hall.

"Summon the Yinan Zhierlang and follow me to the Zhenzhou to inspect." Shao Shude ordered.

"As for orders!" Without any nonsense, Chu Shenping immediately responded.
Chapter completed!
