Huang Taiji couldn't wait to eat his flesh and sleep on his skin, so he handed Hu Blind a map, walked down the city, and continued to go back to make books.

It's not interesting to stay here, there is no heavy firepower like Hongyi cannons, there are no siege equipment, no matter how superb the riding skills of the Eight Banners are, they can't capture Beiping for a while.

Yuan Chonghuan has already returned to defense, and it won't be long before the Jurchens will be driven away.

Zhu Shun returned to the courtyard he rented in the capital, and just sat down in his small room, the third uncle Zhu Zhongli walked in in a hurry: "Shun'er, is there any other way to make the spinning machine work." ”

Speaking of the two water-powered spinning machines stored in the yard, the third uncle Zhu Zhongli was distressed and straightened out his teeth: "On the day I stopped, I would earn six or seven dollars less silver, and the third uncle was distressed." ”

With the character of the third uncle, he should have come over a long time ago, but he didn't expect to come after holding back for more than half a month, but Zhu Shun was impressed.

The water-powered spinning machine was originally changed from a hand-cranked Jenny spinning machine, as long as you change it back again, the steps are not difficult, you can install the handwheel and belt.

Besides, those female workers still count on three dollars a month to support their families, and if they don't have this money, the family will starve to death again this year.

Zhu Shun just built these things yesterday, and today he was going to install them, and said with a smile: "Let's go, second uncle, let's go and run the spinning machine." ”

Came to the yard, tossed for a long time, the new transmission machinery was ready, Zhu Shun shook the large runner with his hand, driving the small turn, and the spinning machine began to spin the yarn again.

The third uncle, Zhu Zhongli, smiled and looked left and right, and suddenly remembered something, and began to feel distressed again: "I still have to shake the spinning machine by hand, so that I will have to add one more person." ”

Zhu Shun withdrew his palm and said with a smile: "It's not one person, it's three people, only three people take turns to shake the handwheel, so as to ensure the uniform speed of the spinning machine and prevent the yarn from breaking." ”

The third uncle Zhu Zhongli's mind instantly popped up with the wages of the three female workers, and he said with a sad face: "I have to take out an extra nine coins of silver every month." ”

The third uncle, Zhu Zhongli, is just calculating in small things, and he is still very serious in big things, and no matter how sad he is, he can only accept this result: "Anyway, this money is made for nothing, it's better than stopping here and not making money." ”

Before he finished speaking, he suddenly remembered another thing, and the third uncle Zhu Zhongli hurriedly went out of the back door.

The water-powered spinning machine has been changed back to Jenny spinning machine, and there is nothing Zhu Shun doing here, so I went back to continue compiling books.

The mathematics book has been compiled, and in the next subject, Zhu Shun is not going to write physics, nor is he going to write chemistry, but logic.

Logic, including deductive logic, inductive logic, methodology, etc., is of great help to mechanical research.

There are three necessary conditions for the Industrial Revolution.

The first is sustainable capital investment, the research and industrialization of industrial machinery is a gold-swallowing monster, and a large amount of capital needs to be invested in research before the results of research are achieved.

Not to mention anything else, take the Jenny spinning machine as an example, Zhu Shun knows very well how the Jenny spinning machine should be built, and even the detailed drawings have been drawn.

It wasn't until the family barely scraped together twenty taels of silver that Zhu Shun made the world's first Jenny spinning machine.

Even if it is manufactured, the money earned by Jenny Spinning Machine every month will still be invested in building new Jenny Spinning Machine, forming a virtuous circle of continuous expansion.

If it weren't for the fact that Zhu Shun and Zhu Zhongyi, the general banner, both had money and could barely feed a large family, just eating would have slowed down the expansion of Zhu's spinning factory.

Silver was especially important for the first industrial revolution.

Second, a large amount of cheap land is needed, and the various factories built in the first industrial revolution will occupy a large amount of land, and if each acre of land is like a field, the price will be as high as seventy or eighty taels of silver.

Generally, small spinning mills have to occupy more than ten acres of land, and the land cost is as high as seven or eight hundred taels of silver, where is there spare money to build Jenny spinning machines.

The third is talent, which requires talents like Xu Guangqi and Sun Yuanhua to invent new machinery and promote the process of the first industrial revolution, and also needs a large number of mechanics to operate and maintain new machinery.

Zhu Shun has already thought of a countermeasure for continuous capital investment, and is also promoting this matter, which is to use the first wave of dividends of industrialization to support a group of industrialists.

Cheap land, Zhu Shun hasn't thought of a countermeasure for the time being, so he can only put it on hold first.

As for the third thing, it is also one thing that Zhu Shun is doing, compiling teaching materials, establishing a new school, and slowly cultivating a group of talents and mechanics needed for the industrial revolution.

Even if the textbooks are compiled, they still need financial support to buy land and bricks to build a new school.

The expansion of Zhu's spinning mill is already imminent.
