The two brothers are both of medium height and have similar faces, but the elder brother has a thinner physique, and both of them are radiant.

Song Yingxing said: "Lord Guo, the harvest of overseas rice seeds you brought has doubled, benefiting the people of the whole world!"

In the morning, outside Nanjing, he and his brother witnessed the rice harvest, and they are still excited.

Guo Wendong said: "In the future, as long as there is no war in the world, and the people grow crops in peace and stability, they will not be hungry." It's a pity that Jiannu wants to seize the whole world, and only by eliminating Jiannu can the world be stable. Come on, come on, two gentlemen, you will be picked up and washed by the late life. ”

In the guerrilla general's mansion, there is a small room, which is not only a place for Guo Wendong and important officials to eat, but also to receive guests.

Guo Wendong took the two inside, Song Yingxing and Song Yingsheng took off their luggage from the horse and followed him in, and some soldiers led the two horses into the stable.

Entering the reception room, the attendants served tea, and the three of them sat down.

Guo Wendong said to Song Yingxing: "Mr. Song, I have heard of the book "Heavenly Creations" in my later life, which involves a wide range of technologies and a lot of content, but I hate not to see it. Mr. must have put a lot of effort into writing this book. ”

Song Yingxing sighed with emotion: "Yes! The book "Heavenly Creations" has taken me several years of painstaking efforts, so that even my career has been delayed, and I have now brought the book. ”

Immediately, he took out three books from his gift bag and handed them to Guo Wendong.

Guo Wendong took it, and the cover was the four big characters of "Tiangong Kaiwu", as well as the two small characters of "upper volume", and the other two were the middle volume and the second volume, with a total of 18 articles.

When the book is opened, there is not only a detailed technical explanation, but also an illustrated explanation, depicting the names, shapes, and processes of a number of production technologies and tools.

For modern times, these technologies are long outdated, and for this day and age, they are extremely rare. Looking at the contents of the book, Guo Wendong was quickly attracted and wanted to simply flip through the three volumes.

The eighteen articles are:

Nari: Cultivation techniques for food crops

Nafu: the source and processing method of raw materials for clothing

Zhangshi: Dyeing method of plant dyes

Essence: The processing of grains

Salty: An introduction to the production method of salt

Sugarcane cultivation, sugar production, and beekeeping[13]

Pottery: the production of bricks, tiles, and ceramics

Metallurgy: The casting of metal objects

Boat and car: the structure, production and use of ships and vehicles

Hammer forging: Iron and bronze tools are made using the hammer forging method

Burnt stone: the production technology of non-metallic minerals such as lime and coal

Paste: Method for extracting vegetable oils and fats

Finishing: The method of making paper

Hardware: mining and smelting of metals

Good Soldier: How to make weapons

Danqing: The production of ink and pigments

Koji tiller: How to make sake

Jewel: The source of jewelry and jade

For example, in the description of agriculture in the chapter "Nai Li", it is pointed out that the rice seedlings are pulled out and transplanted 30 days after the seedlings are raised, and the seedlings of one mu of seedling field can be transplanted into 25 acres; It is also noted that there are three buckets of drinking water for upland rice and five buckets for drinking water for late rice, and they will dry up when they lose water.

For example, in terms of sericulture, there are methods for cultivating hybrid silkworms: the yellow cocoon silkworm is crossed with the white cocoon silkworm to breed the brown cocoon silkworm; The "early male" and the "late female" were crossed to breed the "Jia Seed".

Guo Wendong is most concerned about military-related technology.

For example, in terms of smelting technology, there are descriptions: such as "Where the method of soldering iron, Western countries have strange medicines." The Chinese small welding uses white copper powder, and the large welding is trying its best to swing the hammer and force it, and it cannot be strong after a long time. Therefore, there are forged cannons in the west, and China only relies on smelting and casting."

It is also injected with piston blower technology, which is more advanced than European bladder blower equipment. Special chemical heat treatment processes such as copper alloys, rattle molding, iron anchor forging, steel needle drawing, and "pig iron showers" and metal composite materials are also the earliest clear records. In modern times, these fundamentals still apply.

Improving current smelting techniques can lead to the creation of higher quality, high-performance thermal weapons.

Guo Wendong was flipping through the pages, and the two were waiting quietly.

Looking at Guo Wendong's happy and loving appearance, some people appreciate their own research results, and Song Yingxing is pleased. In the past, these technologies were not valued and were treated coldly by the imperial court, which made Song Yingxing very disappointed.

Guo Wendong's emphasis on technology and putting what he had learned to use, coupled with his determination to protect his family and defend the country, were the two major factors that prompted Song Yingxing, who was originally disappointed in the imperial court, to come to Nanjing.

After reading it all briefly, Guo Wendong put the book on the table.

Song Yingxing said: "I wrote this book, which was published in Chongzhen's tenth year, but unfortunately the Ministry of Industry did not pay attention to it, and many technologies have not yet been promoted. ”

Guo Wendong thought to himself that the Ming Dynasty was worried about internal and external troubles, the finances were exhausted, and they were busy coping, and the rulers were simply immaculate, or they did not pay attention to it.

He sighed: "It is a great loss that such a magnificent book is not taken seriously. ”

He also said: 'Technology is the primary productive force', which is the advanced productive force. ”

Productivity? It's a word they've never heard of.

Guo Wendong explained: "The so-called productivity is the ability of people to transform the world. For example, using more advanced planting methods to make food production higher, which is a way for technology to promote productivity; For example, using advanced technology to make cars and boats make travel more convenient and material circulation smoother, which is also technology to promote productivity. ”

Both of them are very tech-savvy people, and with a little hint, they understood it on the spot, and the word is really incisive.

Guo Wendong said again: "Mr. has devoted himself to research and written this book, and he can't bury it here. I told Mr. in the letter that coming to Nanjing to be in charge of weapon production not only allows Mr. to popularize the technology of the three articles of "hardware", "good soldiers" and "smelting and casting", so that Mr. needs to be useful, but also to manufacture more advanced weapons for the army, killing two birds with one stone. As for the official rank, it is still the fifth grade. Mr. made advanced firearms, so that the Jingying defeated Jiannu, it is a great merit, I will definitely play the imperial court, commend the merits of Mr., on merit and promotion. ”

In his later years, someone finally appreciated him, and Song Yingxing felt that although he was a little late, he would not leave too many regrets.

He stood up and said excitedly: "Don't worry, general, I will do my best!" ”

Immediately, Song Yingxing gave Guo Wendong a deep bow, and he was sincerely grateful to this young man who appreciated him.

He pointed at Song Yingsheng again and said, "General, although my brother's attainments are a little poor, he can also help take care of the weapons workshop." ”

Guo Wendong nodded and said: "I will ask the court to appoint Mr. as the chief manager, and he will be the fifth grade; Mr. Big is the deputy manager, and he is the seventh product. ”

Originally, there was an arsenal of the imperial court in Nanjing, and Guo Wendong wanted to set up a new arsenal for him to be in charge of, responsible for supplying weapons and equipment for the Shenji Battalion, as long as Ma Shiying agreed, there would be no problem, and it would operate in the name of the imperial court.

Song Yingsheng thanked Guo Wendong.

Immediately, Song Yingxing took the initiative to say: "General, the self-generated fire gun was invented by Bi Maokang. I have learned a lot, and if I am only concerned about firearms technology, I am not as good as Bi Mou Hong. But if you give me time, I'll be able to figure it out. ”
