The ice cellar was destroyed.

For a while, there will be no more ice.

"Oh my God!"

Fangcao was the first to shout that it was unacceptable!

"No ice?"

"There's really no ice?"

"Isn't it an ice cellar? Let's get some cold water in it, reseal it, and give it a try to see if we can have ice tomorrow? ”

Early the next morning.

It's not dawn yet.

Fangcao squatted outside the slightly trimmed ice cellar, and waited for the day to light up a little before she went inside.

Immediately after coming out, I went back to my room.

lifted Liu Wei's quilt.

"You're still sleeping! Shopkeeper, do you know what a shop would have become if there was no ice? When we do business, we pay the most attention to a credit! ”

"Retreat...... Returned. ”

She pulled back the covers and rolled over.

"What is the retreat? Can you come to the queue to buy peach blossom brew, how many people are short of money? ”

"Then delay, push back."

"Push when? Is it winter? ”

"Push it for a few days, and I'll think about it again."

"What are you thinking?"

"How to make ice."

"Making, making ice?" Fangcao sat by her window and patted her on the back: "You can still make ice?!" ”

"Dear little grass girl, I'm going to be stunned by you, don't bother me, I'm thinking about how to make ice. You push back the time first...... About three days, three days later, let's talk about whether to retreat or not. ”

"Or do you want to retreat?"

"I don't know if I can do it!"

Fangcao was kicked out by her.

Get back.

Lie down.

Continue to think in a daze - how to make ice?

You can use something to make ice, what is that thing called, she remembers that there was that thing in ancient times.

Think, think.

Fell asleep.

I didn't close my eyes all night, and I was thinking about making ice again, while thinking about how to retaliate against Zhou Sheng.

At present, the business of Beauty Workshop is nothing more than soap, washing soap, and peach tea, and some miscellaneous things, but Beauty Workshop is not the only one.

Although there is some business.

But obviously the business is not very good, and maybe sometimes, it is far inferior to the Xinglin Medical Center opposite.

For Zhou Sheng.

As his only property, Beauty Place, if he suffers a fatal blow, he should be so angry that he vomits blood, right?

How do you deliver a fatal blow?

Suddenly.

A flash of inspiration.

Roll over and sit up.

At this moment, there was one more word on his lips.

Niter.

"That's right! Saltpeter! ”

Belch......

Two questions.

First, what is the scientific name of saltpeter today?

Second, where is she going to find it?

turned his gaze to Dong Xinglin.

"Hello, Doctor Dong, I have something to ask."

Dong Xinglin shrunk his neck: "What do you want to ask me for?" ”

"There's something, I don't know what it's called, and one of them is called nitrate."

"You...... I ......"

Dong Xinglin had an embarrassed expression.

"Or ...... You ask the others, I still have something to do, I have an appointment with several ladies today, and they ......"

"No, don't go!" dragged Dong Xinglin back to his house.

Smack-

Close the door.

Dong Xinglin struggled: "You, what do you want to do, this is ...... in broad daylight"

"If you can't think of it, you can't think of it. I went on to say that this kind of thing...... Eh...... Heat-absorbing ...... in water"

They tortured each other like this for a full hour.

In the description where she couldn't find a clue.

Dong Xinglin fell asleep.

"Smack!"

Slam the table.

"Wake me up!"

"But ...... the 'Pu Xiao' mentioned in "Shennong's Materia Medica"?"

"What?"

"According to the "Shennong Materia Medica", Pu can transform seventy-two kinds of stone ......"

According to the chemical properties of 'Pu Xiao' depicted by Dong Xinglin.

She guessed it was saltpeter.

Although the words are not the same.

"Where can I get it?"

"There are pharmacies, but the amount should not be enough."

Xinglin Medical Center has it.

It's just that it's really only a little bit of a loss.

Experimented.

"Hahaha!"

"Shopkeeper, you ...... The smile is so oozing. ”

"Get me more of this! Hurry, hurry! Grabbing Hong Zhenwu, she whispered: "You must be low-key, you can't let others know, change to a different person to buy it, and dress up in disguise." ”

Steward Dong said: "The Pu Xiao in the pharmacy is generally expensive. ”

"Where's the cheaper? I want a lot. ”

"Moss Town."

"Why Mosstown?"

Steward Dong explained to her: "I also happened to learn that when firing porcelain, when coloring, a thing called flame nitrate is commonly used, which is used for peacock green glaze, and flame nitrate is quite similar to the common Pu Xiao in the pharmacy, and I am not sure that it must be Pu Xiao." If it is really Pu Xiao, and can achieve the desired result of the shopkeeper, go to Moss Town to buy flame nitrate, then it will definitely save a lot of money. ”

Immediately.

Send Steward Dong to Moss Town.

In fact, because Moss Town and other places are famous kiln burning sites, there are several mines nearby, which are specially used to dig some things needed by kiln factories, and nitrate ore is one of them.

Through Ah Kun, I found three face-to-face guys and went to Moss Town with Steward Dong.

When I returned, it was the afternoon of the third day.

The four stewards of Dong pushed a cart and came to Luqiao Lane.

No need to ask.

"Come on, move in."

"Uncle, guard, not a single fly can fly in!"

The two Uncle Hong the guys and guarded the gate strictly.

What kind of gate are you keeping?

Just turn it off.

Insert a sentence - the fashion is not closed at this time, so it gives thieves an opportunity to take advantage of it.

Let's close the door obediently.

What the night does not close.

That's just a fairy tale.

Nitrate ice.

As early as ancient times, there were already ones.

This thing is mentioned in the kiln materials and the "Shennong Materia Medica", but the name is different, it's, the name was used, frost, bitter nitrate, fire nitrate, Northern Emperor Xuanzhu, etc., and the words used in later generations are different, but the general performance is the same.

Nitrate absorbs heat and cools down when exposed to water.

Actually, the operation is also very simple.

Step 1.

Take a large basin.

Half of the basin is filled with water.

Step 2.

Let's have a big vat.

The jar is filled with one-fifth of the water.

The third step is to put the basin in the jar.

Step 4.

Throw the saltpeter into the basin.

……

The little monkey asked her to sit in the front seat, and she sat down nearby.

"Look here, do you see, king, is it written?"

The little monkey stood in front of the black plate, holding a small white piece in his hand, and wrote the word "king" on it.

"Here I can see the Master's writing."

"That's right! In the last row, you can see the Master's handwriting! ”

Out of this classroom.

The little monkey pointed to a nearby classroom: "That's a medical classroom." ”

"Medicine?!"

"In addition to the basic knowledge and physical fitness class, we will also have a medical class, and there will be doctors from the medical center to teach us to identify medicinal materials and some basic case knowledge."

"After studying, isn't that a doctor?!"

"You're not too bad! How many years does a doctor have to study? In just these three years, how can you be a doctor, but being a medicine boy should be no problem! ”

"You come with me, and there are two teachers, are you going to plan to do it?"

"No, it won't."
