Chapter 1748

Item name - Jade of Vertical Thorns, level - Chinese artifact.

Function: Giving this item to the king of a country can force the other party to do something.

After Lu Yan read the information about the Vertical Thorn Jade, he was ecstatic.

With this thing, he can launch a request to the surrounding countries

"Seal all these things in the treasury." Lu Yan was also very excited.

The most treasured treasure of Emperor Wu of Liang was gold.

The dense gold made it difficult for people to open their eyes.

I don't know how much time this money can save the Yun Kingdom.

Lu Yan looked at Tian Yan , eyes full of admiration.

This time, things were done well.

Especially some young people who were secretly dead and injured, they will definitely not be able to make an impression on Yun Guo in a short period of time.

Lu Yan was a little surprised. Yes, Xiongba was shot to death by Hou Yi with an arrow in this battle for the treasure. Xiongba

's death caused the whole world to fall apart.

It also aroused the covetousness of other forces.

Wushuang City, Tianmen, and Zhujian Villa all Set your sights on Tianxiahui.

There will definitely be people coveting the power left by Tianxiahui. When the time comes, the world will be in chaos.

War will break out.

Yun State can use this period of time to develop.

Lu Yan has people transport gold to the treasury Among them, they were sealed.

And he left some behind and went to the"Golden Platform" to summon some other types of talents. The

Yun Kingdom not only needs strong generals, counselors, and internal affairs talents, but also other people to fill all walks of life in the Yun Kingdom.

What Lu Yan needs is not a single flower, but a hundred flowers blooming.

Lu Yan came to the Golden Platform and summoned special talents in culture.

For the first time, Lu Yan summoned a special talent - Song Yingxing.

Song Yingxing was very talented.

In the history of China, that He is also a well-known talent.

Song Yingxing's status in Chinese history is no worse than that of others.

Even worse.

Song Yingxing was a famous scientist in the Ming Dynasty. He was born in Juren. In the seventh year of Chongzhen in the Ming Dynasty, he served as the county magistrate of Jiangxi Province. Later, he also served as an official in Tingzhou Prefecture in Fujian and the magistrate of Bozhou in Nanzhili.

Song Yingxing devoted his life to the scientific investigation and research of agriculture and handicraft production, and collected a wealth of scientific information; at the same time, his advanced ideological consciousness made him a leader of feudalism. A critical thinker of doctrine and medieval academic tradition.

Song Yingxing's writings and research fields involve different disciplines of natural science and humanities, and his most outstanding work"Tiangong Kaiwu" is known as the"Encyclopedia of Craftsmanship in the 17th Century".

Lu Yan did not expect that he would be so lucky.

It was Song Yingxing at the beginning.

Lu Yan also knew about Song Yingxing's"Tiangong Kaiwu".

It is recorded in middle school history textbooks.

Song Yingxing's main contribution is that he compiled the Chinese It has made a summary of the knowledge on agricultural production and handicraft production that has emerged over the past millennium. It has also made a summary of technical experience, systematized and organized it, and then written it into a book so that it can be circulated. Come down.

The books written by Song Yingxing include agriculture, handicrafts, such as machinery, bricks, ceramics, sulfur, candles, paper, weapons, gunpowder, textiles, dyeing, salt making, coal mining, oil extraction and other production technologies.

In terms of agriculture, Song Yingxing The whole process of rice production including soaking seeds, breeding, beating seedlings, and cultivating rice is recorded in detail.

For example,"It was kept for several days, and then it sprouted, and it was sown in the field. When it sprouted, it was named Riyang." When the seedlings are thirty days old, they are pulled up and divided. When the seedlings expire, they are old and have long knots. They are planted in the acres, and they produce a few grains and bear fruit. At the same time, he also pointed out various issues worth noting in rice cultivation. In the handicraft industry, Song Yingxing tried to use quantitative methods. When describing the production process, he paid special attention to the quantitative relationship in raw material consumption, finished product recovery rate, etc., and had a clear concept of quantity.

When analyzing the transplantation of rice seedlings, Song Yingxing pointed out:"One acre of rice field can produce twenty-five acres of rice for transplanting." That is, the ratio of rice fields to fields is 1:25. This important ratio data is still followed in modern Jiangxi..

Song Yingxing gave a preliminary explanation on the oil yield of various oil crops:"Fax, castor beans, and camphor seeds can get 40 kilograms of oil per stone. Cailvzi can get 27 kilograms of oil per stone. Brassica seeds can get 27 kilograms of oil per stone. Thirty kilograms of stone……"

This specific and accurate data description of oil crops has both theoretical significance and practical value.

In particular, the"Machinery" chapter describes in detail agricultural machinery and tools including vertical-axis windmills, sugar carts, ox-turn rope pullers, and brine extraction, which is of extremely high scientific value.

Song Yingxing was the first scientist in the world to scientifically discuss zinc and copper-zinc alloy (brass).

He clearly stated that zinc was a new metal and documented its smelting method for the first time. This is one of the important achievements in the history of ancient metal smelting in my country.

For a long time, China became the only country in the world that could smelt zinc on a large scale.

The method of refining brass using metallic zinc instead of zinc compounds recorded by Song Yingxing is the earliest record in human history of directly melting copper and zinc to obtain brass.

Song Yingxing paid attention to discovering the essence from general phenomena, and also made some achievements in natural science theory. Reflected in biology, chemistry and physics respectively.
