Early the next morning, Xiao Hanzheng went to the county office with some saltpeter on his back.

When Mo Qingling heard that Xiao Xiucai wanted to see him, he was a little inexplicable.

He had heard the name of Xiao Hanzheng, the first Xiao Sanyuan in Nanxi County, and he was famous.

But what impressed him the most was Xiao Hanzheng's little daughter-in-law who tied the husband to complain last time.

He had something to do at first, but he put it down and let Xiao Hanzheng be called in.

Xiao Hanzheng is a scholar, so he does not need to bow down when he sees an official.

He saluted Mo Qingling as a scholar, "The student has seen the adult!"

Mo Qingling looked at the gentle and elegant young man who walked in, and he couldn't help but feel a little favor.

Xiao Hanzheng's temperament does not look like a scholar from a poor family in the countryside at all.

Mo Qingling was only a few years older than Xiao Hanzheng.

But he still appreciates his talented peers.

A smile appeared on his stern face, "No gift, please take a seat!"

He asked straight to the point: "You came to see me today, what's the matter?"

It is really busy with business, and there is no extra time to waste.

Xiao Hanzheng knew what kind of person Mo Qingling was.

He also bluntly stated his intention, "I really have something to discuss with the adults today."

"My lady's master once taught them how to make ice. She is grateful for the master's kindness, so she wants to make this method public."

"Anyone who wants to learn how to make ice can do it."

"It's just that the Wu family wanted to forcefully buy this recipe, but my wife didn't want to waste his master's efforts, so she refused."

"We are afraid that if we teach people to make ice in the village, the people of the Wu family will not agree to destroy it."

"That's why I wanted to come and ask the adults, can I borrow the free space of the Xia County Government and let me teach you how to make ice."

"Firstly, people in the county can put ice basins at home to relieve the heat, and secondly, they can make some ice drinks to earn some extra money."

He paused again, "Of course, if adults think this recipe is useful, it can also be presented to the capital, so that more people can learn to make ice and relieve the heat."

Although Mo Qingling was very busy in the county office, he knew what was going on in the county seat.

So he has actually heard about making ice in summer, and he is still a little skeptical.

I never thought that Xiao Hanzheng and his wife would be so generous, not only to donate the recipe for free, but also to teach everyone how to make ice.

This is also a good thing for the people, and he will naturally not object.

But he still asked, "Have you made up your mind?"

Xiao Hanzheng nodded, "I've thought about it, I hope the adults will do it!"

Mo Qingling sighed that Xiao Hanzheng and his wife were really courageous and had a better impression of them.

"Since there is such a good thing, this official will naturally fulfill it."

He asked curiously, "Is it difficult to make ice?"

Xiao Hanzheng replied: "It's not difficult, it just needs one thing."

"I've already brought it. Would you like to make ice on the spot for the adults to see?"

At that time, watching his little daughter-in-law make ice, he thought it was amazing.

So seeing it with your own eyes is more convincing.

Mo Qingling also wanted to see, "Okay!"

So according to what Xiao Hanzheng said, someone found a large wooden basin and put it on the ground, and put a small wooden barrel inside.

Water was added to the bucket and tub.

Mo Qingling and the people from the county government then saw Xiao Hanzheng take out a few small white stones from the basket and threw them into the big wooden basin.

"Wait a moment, the water in the small wooden bucket will freeze."

Mo Qingling and the people from the county government office: "..." Why does it feel so unreliable.

Throwing a stone into a water basin makes the water in the unstoned bucket freeze? real or fake?

Mo Qingling's suspicions deepened, but he still did not refute.

"Okay, then I'll work first, you drink tea for a while, and I'll come back when the ice is ready."

Not long after he took over Nanxi County, the previous magistrate had a backlog of official duties.

Since he came here, although he didn't really come here to be the county magistrate, he still wanted to do a good job because he was looking for a job in his position.

Xiao Hanzheng nodded, "Sir, feel free!"

The yamen in the county government kept staring at the barrel curiously.

After a while, one of the yamen couldn't help shouting, "The water is really freezing!"

The other yamen also walked over to see, "It's really frozen, it's amazing."

"As expected of an old fairy, he can come up with a way to make ice in summer."

"The apprentice of the old immortal is also smart and has learned everything."

A group of people sighed around the tub, and soon Mo Qingling also came out from the inside.

Seeing that the water in the barrel was really starting to freeze, he was shocked.

Seeing is really believing, otherwise he would have a hard time believing it if he heard others say this method.

He is also a wise man, "This water can freeze, does it have something to do with the white stone you just threw?"

Xiao Hanzheng replied: "Yes, this is saltpeter, which can be used medicinally, and some Taoists will use it to make pills, and you can buy it in drugstores."

Mo Qingling quickly asked the point, "If I use this saltpeter to make ice, will it cost a lot of money?"

Xiao Hanzheng said truthfully: "If you go directly to the saltpeter, you will just spend some time and energy, no money."

"If you buy it, it will cost a lot."

The cost of making ice with saltpeter is not low, and they did not want to promote it nationwide.

Open, anyone can use it.

But this method is published so that everyone can learn it.

It is also conducive to the development of saltpeter mines.

When poor people find saltpeter, they can also be transported to the city and sold to big families to improve their lives.

The key point of the little daughter-in-law is to let people in the county take the initiative to develop the saltpeter mountain near the Taoist temple, so as to make a way for everyone while making profits for everyone.

When the saltpeter mines are almost fully mined, their workshops should be able to drive fire.

When the little daughter-in-law thinks about things, it is often linked to each other, so that he can't help but admire it.

As soon as Mo Qingling heard it, he knew what Xiao Hanzheng meant.

It seems that this method of making ice requires a high cost.

Most people are afraid that they can't use it, but it can also benefit the poor who are lucky enough to find saltpeter.

Of course, this approach is definitely better than nothing.

How many years have the girders been built, and after the war stopped, many places are waiting to spend money.

The external expenses of the imperial court are huge, and the household department is often short of money. Now the palace still uses the ice storage of the previous dynasty.

The amount of ice stored is limited, so the palace is also short of ice every year.

There are many concubines and ministers who ask the emperor for ice in summer.

If this method is offered, the sage will surely be happy.

Mo Qingling thought for a while and said, "Write down this ice-making method, and I will send someone to the capital to dedicate it to Your Majesty, and let the people of Daliang learn it."

For the sage and the court, the reputation among the people is also good.

Then he added, "The source of this ice-making method, you also wrote it down on paper."

This also means that he will let His Majesty know that this recipe was brought out by Xiao Hanzheng and his wife.

He will not be greedy for the credit of the two of them.

Also let the ice-making method have a source.
