Deng Yuhan's mechanics partner Wang Zheng is already under Wang Hongyu's command, and the two of them will meet many years earlier than in their previous lives, and the steam engine researched by Wang Zheng in their previous life is no longer afraid of being stolen by Watt, and the two must have made great achievements in mechanics and machinery.

In this way, mechanics will not be left out in the cold, I believe that Li Tiezhu will learn all his knowledge, and he will dig out more things.

Astronomy will also be useful, and Wang Hongyu will definitely find suitable students for him, open up his treasure trove of knowledge, and let astronomy flourish in China.

Under his guidance, Deng Yuhan could also explore chemistry, and his Western medicine had good achievements.

Chemistry has not yet been discovered by human beings in this era, and it is still primitive chemistry in the East and the West. In the West, it is called "alchemy", and in the East, it is "alchemy".

It was not until 30 years later that the initial development of chemistry began.

From that time on, the West called oxygen phlogiston, and Song Yingxing at the end of the Ming Dynasty at the same time called the basic element of chemistry "Yuanqi".

After that, in the East for 200 years, chemistry did not advance an inch.

In Russia, which is more marginal in the West, Mendeleev is about to come up with the periodic table.

Of course, Wang Hongyu cannot directly develop the chemical industry, but at least he can promote the simultaneous development of philosophy and chemistry.

Deng Yuhan and Song Yingxing together can launch the "Yuanqi" atomic theory of the East.

Then, whether it is a metaverse punk or a petrochemical industry, we will talk about it then.

However, the basis of chemistry is oil, Wang Hongyu can remember the location of some important oil, this life must let China occupy the opportunity of oil, so that there is the foundation of chemistry and modern industry.

Deng Yuhan is close to 1.8 meters tall, slightly chubby, with natural curly hair in a black shawl, seven points similar to the Newton portrait that Wang Hongyu had seen in his previous life, forty-five or sixteen years old, with a white face, no beard, and a Chinese accent in Chinese.

Wang Hongyu, Jin Nige, Bi Fangji, and Long Huamin set up wine for Deng Yuhan and the others, and they talked very happily. Although Yunyang is remote, the scenery is beautiful, which is very suitable for people who do learning, and Deng Yuhan likes it very much.

A few days later, Wang Hongyu announced that Deng Yuhan was the administrator of the mobile library of the Beijing Academy and a lecturer in astronomy, medicine, mechanics, mechanics, biology, and chemistry.

Jin Nige, Long Huamin and the others widened their eyes, they only mixed a librarian in the mobile library of the Beijing Academy, and Deng Yuhan became a lecturer in six disciplines as soon as he came.

They know that at present, lecturers are the highest title of the library, and their treatment is the same as that of the director, and the library does not have a position of director at all, and even Wang Hongyu only has the title of librarian.

This time, Deng Yuhan and his entourage brought a lot of tomatoes from Macao, as well as many tomato seeds. They are very fond of this ornamental plant and plant it in their own yards and on the slopes of Yunyang Mountain.

This is a good thing in later generations, it can be used as both fruit and vegetable, and its nutrition is higher than that of ordinary vegetables. Wang Hongyu washed a few and began to eat.

This frightened Deng Yuhan and the others, shouting: "It's poisonous, you can't eat it!" It was too late to stop it, and I watched Wang Hongyu swallow a tomato in three bites and two bites.

Wang Hongyu said: "It's not poisonous, this is a good thing, don't you believe you can taste it?" Several people were so frightened that they retreated. But Wang Hongyu not only did not get poisoned, but ate two more.

He also made a jar of tomato sauce from tomatoes and scrambled eggs with tomatoes at noon. In order to keep the seeds, Wang Hongyu always got out the tomato seeds in advance, and even the few he had just eaten, he spit out the seeds and put them in a clean place to dry.

Long Huamin thought that the seeds were poisonous, but Wang Hongyu said that he would wait for next spring to be used as seeds, but in fact, they could grow after the autumn, but the temperature was low and only flowered and did not bear fruit.

I heard Deng Yuhan say that there was a piece of something that was brought to Macao from Nanyang, saying that it was brought back from the Americas, and it was delicious. I don't know if I can grow it, but I brought a lot of it this time, and it's still on the ship.

Wang Hongyu hurriedly went to see it, it turned out to be peanuts, Wang Hongyu also asked Xu Guangqi to look for it, and there was nowhere to find it when he stepped on the iron shoes, so it took no effort to get it.

Peanuts are suitable for sandy planting, Qixian is the main production area of peanuts in later generations, and can also be planted on the slopes of Yunyang Mountain, the introduction of tomatoes and peanuts, the sauce factory can greatly expand production; Peanuts can also be extracted for oil.

Wang Hongyu began to lay out the Chinese food industry, and now the economically developed areas in the south are different from the areas in the north that have not yet solved the problem of food and clothing, and many places in Jingxiang have appeared in the township catering industry, and the densely populated streets of the city have been full of shops.

Therefore, the development of the catering industry is currently mainly considered in the south of the Huai River. Scrambled eggs with tomatoes, Portuguese chicken, and egg tarts are all a combination of Chinese and Western cuisine, and have since become part of Chinese cuisine.

The development of Chinese food should first consider the abundance of catering materials, and on this basis, a variety of foods can be excavated, but the enrichment of diet must also be carried out under the conditions of economic development.

The following crops are all crops that have been introduced or not introduced from South America and Nanyang at this time, and how many have not yet been introduced, Wang Hongyu should pay close attention to the introduction, cultivation and promotion.

】

Sweet potato, corn, potato, peanut, papaya, pepper, sunflower, olive, coffee, cashew nuts, tobacco, onion, cabbage, cotton bean, avocado, cocoa, kidney bean, pineapple, guava, American ginseng, upland cotton, custard, apple, etc.

Deng Yuhan also made great achievements in botany, and after coming to Yunyang, he became fascinated by this large mountainous area that divides the climate between the north and south of China.

After half a month of investigation, Deng Yuhan proposed to Wang Hongyu to establish a biological laboratory in Yunyang, and also to establish a number of plant cultivation bases, and asked to go to Shennongjia for investigation.

He said that Zhuxi County, Zhushan County, and Shennongjia have different climates in spring, summer, autumn, and winter. In summer, there are snow-capped mountains, and in winter, there are spring-like basins. It is a natural breeding base for animals and plants.

Animals and plants in the tropics, temperate and cold zones can find a place to settle down here, and any animal and plant in the world can be cultivated here, changing the growth environment, and cultivating new varieties that adapt to various climatic conditions as soon as possible.

He found that the closer he got to Shennongjia, the more the plants mutated, and it was possible that the Shennongji area had a special geology and needed to be investigated in depth, which was of great help to him in cultivating new plant varieties.

So much has happened in three days.

Finally, the new governor of Yunyang came.

Cai Fuyi, the founder of the "Great Wall of Miaojiang", arrived as the new governor.

He was under the joint attention of Tianqi, Wang Hongyu and the cabinet court.

This time it arrived with a mission.

When he was promoted, he received a secret edict and was carrying a secret, ready to cooperate with Wang Hongyu in civil and military cooperation and sincerity, using Yunyang as the rear base to deal with the upcoming rebellion of luxury and peace, and promote the substantial transformation of the southwest and return to the stream.
