Han Jiang turned around and handed the wooden stick to the maidservant beside him, and all the family members retreated.

Han Jiang shouted: "Enough fun, several foremen are patrolling the workshop with me, I want to see how your work is." Also, little ones, one stone of rice and five catties of sugar will be burned for you today. ”

The children cheered.

The onlookers are not stupid, Qian Xinyao's daughter is wearing men's clothes, most of the men may not be able to see it, but the mothers-in-law of Baiyufang are sharp-eyed, and then look at all the family members retreating, all of them are replaced by maidservants, Danxia is a snack goods, and she didn't take the waist card of Qianfu on her waist, who is this? You can guess it.

When Qian Xinyao took the wooden stick tied with red silk, an amazing scene appeared.

All of them.

There was no one to command, and everyone present solemnly saluted Qian Xinyao.

This gift is for Qian Xinyao, and it is also for the Qian family.

The Qian family is very good.

There are even rumors in the market that the eldest girl of the Qian family met the young monarch of the Han family on the river, and the eldest girl of the Qian family led the young gentleman of the Han family to be kind, and this is why there is Baiyufang.

Baiyufang was built because of the eldest girl of the Qian family.

Of course, what is the fact, and who cares about the truth.

Rumors are always more interesting than the truth.

Half an hour later, another explosion rang out.

Soon, on the sandy playground outside a newly built Mengxue Hall in Baiyufang. Because this place has been completed and the craftsmen have been evacuated, the residents of Baiyufang are very interested in definitely not coming within a hundred steps.

Han Jiang stepped on the sand with his bare feet, thinking about his new plan to make money.

Qian Xinyao sat on the swing next to the sand, slowly rocking.

After a cup of tea time passed, Qian Xinyao spoke: "If there is no weaving, okay?" ”

Han Jiang shook the folding fan lightly: "When it comes to our status, do we still need a piece of clothing to reflect our dignity?" Ming, you ordered someone to post a notice in Baiyufang, saying that you would pay to sponsor 100 girls aged 13 to 16 in Baiyufang to enter the women's school, and I have prepared what they want to learn, and I will need 5,000 female accountants in the next five years. It's a pity that there are less than 120 people of school age in Baiyufang. ”

Qian Xinyao asked, "And then?" ”

"Then, the people of Lin'an Mansion will guess that you will exchange your dowry or wedding dress for money to fund women's education. This light is much more gorgeous than your new clothes. ”

"This is a slippery head, a trick and a greedy name."

"No, it's a win-win. If you're not convinced, go back and embroider yourself. ”

In a word, the choked Qian Xinyao wanted to bite Han Jiang.

Well, in order not to embroider, admit it.

Qian Xinyao agreed: "Okay, just do it." What about you? ”

"I, I've been a little poor lately, and I'm also wearing plain clothes, just find a red gown to wear. Some time ago, I invested in several porcelain workshops in Jingdezhen and invested in it, but the profits have not yet arrived. There has been a recent batch of investments, which are a bit large. ”

Hearing Han Jiang say this, Qian Xinyao said: "I can't move my dowry, but I have saved a lot of profits from soap, how much money do you need?" ”

"Seven hundred million dollars."

As soon as Han Jiang said this, Qian Xinyao almost fell off the swing.

Soap is saved a little money, a lot, millions of dollars.

Han Jiang's 700 million scared Qian Xinyao trembled.

Qian Xinyao asked in surprise: "You, what are you going to do here, you want 700 million money?" ”

"It's 700 million a year."

"Do what?" Qian Xinyao couldn't figure out what to do and needed to spend so much money.

700 million yuan, exchanged for rice, can fill the Qian family's current bad grain ship, more than 100 boats of rice. A boat can hold 3,000 stone meters and a hundred ships.

Han Jiang turned his head: "Plant sugarcane." ”

Han Jiang didn't tell the truth, because he hadn't gotten married yet.

Qian Xinyao didn't believe it: "It costs so much money to grow sugarcane? ”

"There are also sugar mills, and docks also need to be built, and these are all things that cost money. There are a few other things, this is all going to cost money, but don't worry, 700 million is nothing, and it is estimated that it will be solved next month. ”

Qian Xinyao could tell that Han Jiang didn't tell the truth, at least he didn't tell himself everything.

Maybe I haven't passed the door yet.

The powerful people in Lin'an, if they talk about family property, there are not a few who can come up with 700 million yuan. But those are all Zhuangzi, shops, treasures, and real estate. If you can take out 700 million in cash, you can't get a lot of money.

The Han family, there must be.

But taking out 700 million at once is also a huge amount for the Han family.

Han Jiang took out a small box from his arms: "For you, this thing was researched by Shi Daochang, but he didn't continue, it was finally made by my Han family craftsman." Because Shi Daochang doesn't care about these playthings, he cares more about people's livelihood, so his research direction is for the people, so I asked my own craftsmen to complete this. ”

Han Jiang didn't hand the small box to Qian Xinyao, but just put it in a position that Qian Xinyao could reach.

When Qian Xinyao reached out to take the small box, Han Jiang had already raised his feet and left: "Ling'er, after the wedding, I will tell you a secret, a secret that only belongs to you and me." ”

After speaking, Han Jiang had already left.

Qian Xinyao opened the small box, and inside was a round piece of wood.

When I turned the wood chips over, it was a very bright mirror.

After iron plating, chromium, and then grinding a copper mirror.

Qian Xinyao has seen bright steel, which can also be ground like a mirror, but if it can't be maintained, it will not be clear in a few days, and it will rust in half a month.

Isn't this thing afraid of rust?

Shi Ziyan didn't continue his research, he was more concerned about the other, cheap galvanized iron sheets, because Han Jiang said that as long as cheap galvanized iron sheets could be made, he would have a way to keep food for up to a year.

In this way, the fruits of the south and the meat of the north can be traded from the north to the south.

Therefore, Shi Ziyan threw away all his work and devoted himself to the research of cheap galvanized iron.

There are several major problems in this research, the first is the rolling technology mentioned by Han Jiang, the second is galvanizing, and the third is to ensure the strength, and the most difficult is the cost.

If you can't make a piece of iron sheet for a few dollars, it doesn't make sense.

The steel mirror in Qian Xinyao's hand is the original version of chromium-iron-zinc alloy, which is of epochal significance, and its significance is far more than the value of a mirror ten million times.

Many industrial technologies in the Ming Dynasty were actually a restoration of the technology of the Song Dynasty, and they were only improved in the late Ming Dynasty.

If it weren't for the death of the Yuan Song Dynasty.

Where the Industrial Revolution took place, it's really unknown.

Shi Ziyan's mastery of metallurgy had already shocked Han Jiang to the point of suspecting that he had read fake history before he crossed over.

Since Shi Ziyan learned the basic knowledge of acid, alkali and salt from Han Jiang, a new door opened to him, and he already knew that fire nitrate is a kind of nitric acid with low purity, which is mixed with glycerin and nitrated to become nitroglycerin, alkali is not caustic soda, it is the soda ash of sea salt alkali made by Han Jiang.
