After a while, Zhao Dagou came back with five hundred taels of silver.

Li Guo handed the silver to Song Yingxing's hand, "Four hundred taels is the salary, and this one hundred taels will be used as pocket money when your family comes." ”

"It's too much to say how this works!" Song Yingxing's family has defeated him in the past few years, and he has never seen so much silver.

Li Guo laughed, "More? Do I still feel less? Others don't understand you, I understand you! Others don't know your worth, I know! ”

In one sentence, Song Yingxing's heart was warm, when did he receive such courtesy, and stood up at the moment, "In the next down-and-out person, he was so loved by General Li." Okay, I promise you, I'll go back to my hometown overnight and bring my family! ”

Li Guo grabbed Song Yingxing, "You don't have to run around for this matter, you write a letter, and I will send someone to pick them up and ensure that they are comfortable and safe to come and meet you." ”

Li Guo is not afraid that the five hundred taels of silver will be gone, what he is afraid of is that Song Yingxing will run away!

But Li Guo thought that it was a little redundant. Song Yingxing is living a depressed life now, he originally wanted to seek a job, he has an income of dozens of taels a year, coarse tea and light food, and then do some simple research, just get by. Now Li Guo gave him four hundred taels of silver a year, which is a lot.

In addition, everyone at that time regarded Song Yingxing as an unprofessional person, and they didn't care about him, so they were very pessimistic. And as soon as he saw Li Guo, Li Guo actually regarded Song Yingxing as a treasure! This flattered Song Yingxing. Song Yingxing really didn't understand why he was worth so much money.

Song Yingxing actually didn't ask for extravagance at all, and General Li didn't say anything when they met. gave such a large sum of money, but how to repay it?

Song Yingxing took the silver from Bai Huahua and was happy in his heart. wrote a letter to his family at the moment and handed it to Li Guo, asking Li Guo to take his family members.

Li Guo immediately ordered someone to call Luo Hu, bring more people, take the Guan Fang Seal Letter, and go to pick up Song Yingxing's family overnight to prevent Song Yingxing from changing his hexagram.

This time. Both were reassured. One is thirsty for talent, and the other has been a bosom friend for a long time. One is a college student with modern theories but no practical experience, and the other is dissatisfied with the current situation. Thinking about the first talent of innovation. It was like a home at first sight.

When the two of them got together, the chatterbox opened, and they actually put aside the master Guangxi to appease Tu Shaoxuan. In the end, Tu Shaoxuan really couldn't bear it. I went to sleep. But two people don't care.

Li Guo once read this book in the library, but at that time he only understood it, not in depth, only knew that the book covered a wide range of topics, and some of the methods proposed in the book were still applied until modern times, and the technology in this book was quite advanced at that time.

So Li Guo asked tirelessly.

That Song Yingxing was soft with the silver, and he had no money for all these years even to take the exam and engage in research. As the so-called people are poor and short-minded, now I see Li Guo asking. You know everything, and you can say everything.

Listening to Song Yingxing's lecture on one aspect at a time, the more Li Guo listened, the happier he became. He didn't expect that this Song Yingxing was really amazing. Anyway, let's just say that, agriculture, handicrafts, machinery, bricks, ceramics, sulfur, candles, paper, weapons, gunpowder, textiles, dyeing, salt making, coal mining, oil extraction, and so on.

Because this Song Yingxing is amazing. Even later generations of scholars of the Wa Kingdom commented on Song Yingxing's book, "The Study of Creation": "The one who opens things is the one who manages the land, develops the products, enriches the universe, and nurtures the people."

You say awesome, not awesome!

The two of them were drinking and talking, Song Yingxing was surprised, he didn't drink much, why couldn't he get drunk.

Finally, the two men talked about smelting and machinery, and Li Guo intended to guide him in this regard.

Song Yingxing didn't know where he learned what gold, silver, copper, iron, tin, lead, zinc and other metal ore mining, washing, smelting and separation technologies, as well as steel filling, various copper alloy smelting, the methods are all understood, and it is not empty talk.

For example, iron is made from coal, piston bellows are used to blow air, pig iron is directly fried to mature iron, pig iron and wrought iron are combined to make steel, and so on.

In addition, he found that the continuous production process of smelting iron from pig iron directly to mature iron could be completed by using the iron-making furnace in tandem with the iron-frying furnace, which was equivalent to the modern Martin furnace, a device for combining raw and wrought iron to make steel.

You must know that the firearms of the Ming Dynasty were very advanced, but they were limited to the barrel of the gun, and the steel of the barrel was not good, and it was easy to explode when loaded with gunpowder.

Li Guo asked, "Is your steelmaking technology useless?" ”

Song Yingxing smiled bitterly, Li Guo understood that this was because of Song Yingxing's identity, and no one paid attention to it.

In terms of weapons, Song Yingxing also understands very well what kind of cold weapons such as bows and arrows, crossbows, and dry guns, as well as gunpowder and firearms manufacturing technology, including artillery, mines, mines, birds, and 10,000 enemies and other weapons can be made.

"What? Mine? "This Li Guo is also very interested" Is it the kind that rings as soon as the strings are pulled? ”

"There are also those that don't pull the strings." Song Yingxing said.

"Don't pull the strings? The kind that explodes when you step on it? Li asked.

"Ahh What's so strange about this? Song Yingxing didn't feel anything out of the ordinary.

"Good, good!" Li Guo is really satisfied, this is really a treasure.

"There's something you don't know if you can do?" Li Guo asked.

"It depends on something, people always have a limit, you can say it and take a look!" Although Song Yingxing didn't say anything, he was very proud in his demeanor, which means that I can't do it, and others can't do it.

Li Guo took out a pen and paper and drew on it. Song Yingxing watched seriously from the side. After Li Guo finished painting, Song Yingxing shook his head and didn't understand.

Li Guo explained, "This is a sealed iron furnace, which is filled with water, and there is a fire burning underneath, and the pipe above this one leads the steam of boiling water to guide the closed copper box here, and there is a piston inside, and the steam pushes the piston back and forth, and the piston is connected to the lever, and the rod is connected to a wheel. As long as there is steam, the wheel will keep moving! ”

Song Yingxing thought for a long time, scratched his head, and looked at Li Guo, who was full of expectations, "It doesn't seem too difficult, but what's the use of this?" ”

"It works! You'll know when you make it, it's called a steam engine! Li Guo said.

"Steam engine?" Song Yingxing muttered the new name in his mouth.

Li Guo knows that in the history of human development, there have been several major revolutions, among which the steam engine is definitely a very important one.

In fact, the steam engine is not that complicated, and it was invented very early.

The world's first steam engine was invented by the ancient Greek mathematician Helen of Alexandria in the 1st century. Later, Watt only improved the steam engine to make it more powerful.

Due to the invention of the steam engine and the development of the coal and iron industry in Britain at that time, Britain became the first country in the world to use steam to propel iron 'sea ships'. In the nineteenth century, the reform of maritime transport began, and some countries entered the so-called 'steamboat age'. Since then, the ship has sailed on the endless ocean. Subsequently, steam engines were also used in coal mines, factories, and trains. Labor was liberated and the economy developed. This cannot but be said to be the result of the invention of the steam engine.

Therefore, Li Guo was bent on asking Song Yingxing to build a steam engine, of course, Li Guo knew that this kind of thing could not be done in three days or two days, even if it was built in a few years, it was worth it.

"Did you make it? You can go as long as you want! Li asked.

"Okay, I'll make it!" Song Yingxing replied.

Li Guo drank a bowl of wine at once.

Li Guo is very happy now, from the northwest to the southwest, I thought it would be more difficult, but the prospect seems to be very good!

Li Guo still has a lot of plans, and he will implement them step by step! (To be continued......)
