The whole family of villains criticized her wildly, but the princess treated her with medical treatm

There is a special note in the tip: if you make ice in a house on the ground in summer, no matter how much saltpeter you use, you won’t be able to make it!

Lower the water temperature by a dozen degrees at most.

Yan Yang couldn't understand what ten degrees was.But at least you can understand that making ice requires a low-temperature environment like a cellar.

"Bring a big vat and put a hundred pounds of well water in it."

Yan Yang followed the steps written by his cousin and ordered him to go down, "I want water from a deep well."

The soldiers did so.

In the center of the large water tank, there is a smaller bucket soaking, which is also filled with well water.

The white saltpeter is first crushed with a pestle and mortar.This is the second step. The explanation given by the princess is to speed up the dissolution of saltpeter in the well water.

The trick begins——

"One hundred pounds of well water, then weigh sixty pounds of crushed saltpeter, and pour it in."

"Yes!"

The saltpeter was poured into a large vat of water.

Everyone stared intently at the small bucket in the large water tank. However, everyone was disappointed. Even in the low-temperature environment of the cellar, the well water in the small bucket still did not turn into ice.

Yan Yang stepped forward and personally tested the temperature of the water in the small bucket: "It's getting cold again, but it hasn't frozen yet. Add thirty kilograms of saltpeter!"

Another thirty kilograms of crushed saltpeter were thrown in.

"It's frozen!"

"Look, the well water in the bucket has turned into ice!"

The soldiers cheered.

Yan Yang's hanging heart was relieved, and the corners of his elegant lips curled up slightly: "Okay, she was right. This method of making ice with saltpeter is too expensive."

It took ninety pounds of saltpeter to turn the water in a small bucket in the center into ice cubes.

Saltpeter is very expensive. If you use this method to make money, it can be said that the gain outweighs the loss.

It is more practical to store more ice cubes in the cellar in winter.

Qin Zhaoyi was greatly surprised. He was so ecstatic that he picked up the ice cubes in the small bucket and rubbed it on his face: "It's so refreshing, so cool. Don't worry about the cost. There is a saltpeter mine in Liuzhou, which is controlled by the state." Yes, the reserves are huge, we can just drag them over and make a lot of ice!"

Yan Yang nodded: "This method of making ice is too harsh. Without the right time, place and people, it would be difficult to make it in large quantities."

He read the tips several times, and one of them said that the saltpeter that has been dissolved in the water can be dried underground in the sun and used repeatedly.

After working like this for a few days, everyone in the Zhenbei Army used ice cubes.

Under the dual effects of Huoxiang Zhengqi Water and ice making, the heatstroke situation in the military was greatly alleviated, and [-] heatstroke patients recovered quickly.

"Your Highness, you said last time that the soap would be ready for use after a month."

Huang Zhu couldn't wait any longer.

He has lived in Yundu for almost a month, and all the slaves in the eldest princess's mansion have been trained by him.

I want to go home and see.I wonder how Master and Jin Yu are doing, and whether they are doing well in Baidizhou; I wonder if the brothers in Jian Barracks are practicing on time every day.

Mu Tingxue explained: "If you don't leave it for a month, the soap will be highly alkaline and burn your hands too much, which will damage the skin on your hands and face."

Huang Zhu was thoughtful and took out a letter: "Master has received a letter. The letter said that I received a beating, which is a good thing. It is a hundred times better than receiving a reward."

Mu Tingxue said: "Mr. Xiao is a man of great wisdom."

On one side is the queen's twenty-foot plank, a water stick, with small wounds on the skin and flesh; on the other side is a reward for killing, standing you up as a target to attack.

"Master also said that the soap factory has been completed, and the two lime factories you ordered have also been expanded. The lime factory recruits four hundred migrant workers, and is given one tael of silver and half a stone of food every month. The people of Baidi Prefecture are We were squeezing our heads out and fighting for it.”

For many poor farmers who can only earn a few hundred pennies a year due to their busy schedules, this remuneration is really generous!

The half a stone of grain given each month, about 60 kilograms, is enough to keep the whole family from starving to death.

Food, in ancient times, could be used as currency.Farmers pay taxes in exchange for grain, and many commodities on the street can also be exchanged for grain.

"It's a good thing."

Mu Tingxue couldn't help but smile, "When I left Baidi State, I asked Mr. Xiao to spread the news and collect a large amount of lime. Is there any movement in Baidi State?"

"Yes! Master said that several wealthy families in Baidi Prefecture opened several lime-calcining workshops within a month."

Huang Zhu was a little confused, "I don't understand why His Highness still collects lime when he has his own lime factory."

"The demand is huge, the more the merrier. Quicklime is not only used in soap factories, but can also be used to make cement."

Mu Tingxue had her own plan, "To spread the word, let these local wealthy people invest in opening lime workshops and lime plants. The wealthy people will spend their money, so that civilians can have jobs."

Huang Zhu was dissatisfied: "Doesn't that mean these local snakes are making money from lime?"

His parents were poor peasants, and he climbed up from the bottom, so he hated the big landowners and tycoons in the fish and meat village.

"I just want them to make money!"

Mu Tingxue's eyes were extremely deep, "Only when these big landowners, wealthy families, and local snakes taste the capital profits that opening factories can bring, will they stop their desire for land."

Why do they want land so much?It is simply because forcibly buying, seizing, and annexing people's land can bring profits and obtain a large amount of food.

What if an industrial business model emerges that makes more money than land?

Huang Zhu was shocked: "You mean, let the local wealthy families and big landowners in Baidi Prefecture spend a lot of money to open a lime factory, and at the same time recruit a large number of migrant workers, so that they can earn the money for lime, and they will not be keen on robbing them." Is it the common people’s land?”

Absolutely!

At the same time, it solves the work problems of ordinary people, the problem of farmers having no land to farm, the problem of land annexation, and the problem of disobedience of wealthy families.

"Well, it seems that the wealthy landowners have made money, but in fact everyone has made money, the people have a way of living, and the factory has to pay Yunhuang business tax."

Whether it is opening a lime factory or a soap factory, it can be regarded as the germination of industrial capital.

The next morning.

Mu Tingxue went to Qihuang Palace to visit her mother, and made a sweet potato glutinous rice cake with fried potatoes and potato chips for her mother.

The younger brother shamelessly came over to eat and drink, repeatedly hinting that he needed a kerosene lamp. Mu Tingxue was so troubled that she gave him one as a gift.

The Queen Mother likes sweet potato glutinous rice cakes very much.The emperor's younger brother has a special liking for fried potato chips.

“I didn’t expect that there are such interesting ways to eat potatoes, the divine food.”

The potato chips were sprinkled with spice powder, and my brother was like a hamster, eating them crunchily, "Sister Huang is so good."

"If your Majesty likes it, ask the imperial kitchen to make it for you. The method is very simple. Slice it and fry it over high heat until it is slightly brown. If it is too deep-fried, it will become bitter. Drain the oil and put it on a plate. Just add some spices."

Mu Tingxue thought to herself that it would taste better with ketchup.

After feeding her mother and younger brother, and arranging all the matters at the Hubu Yamen, in the afternoon, she took Huangzhu and two cute babies and set off to Baidizhou to officially start the soap factory!
