"Is there saltpeter or not, bring it to me, it will be more." Li Chongrun looked at the old alchemist.

The old man smiled awkwardly: "There are few such things in Shenjing, I used up the alchemy in my early years." ”

"......" is also right, no one was much interested in saltpeter during this period, and there was a little bit of a pharmacy.

took the silver and gave it to the disciple of the old Fangshi: "You go and run an errand and buy half of all the saltpeter in Shenjing." ”

The vast majority of doctors and pharmacies in this period still pay attention to medical ethics, and they will not be willing to sell out, so that people have no medicine to buy.

"I remember saltpeter making ice, as long as the saltpeter sinks to the bottom, the ice floating on it is non-toxic and can be eaten directly." Li Chongrun thought.

He also felt strange why the memories of his previous life always felt clearer and clearer.

Li Chongrun said in his heart: "Could it be that the two souls are one, and I have gained extraordinary abilities in some way?" It's not scientific...... Forget it, crossing is also very unscientific. ”

On Cola's birthday, the old Fangshi disciples ran all the streets, just to find a saltpeter that the master wanted.

The adults in the children's excitement vegetable market also understand that they always feel that their faces are shining when they do things for His Royal Highness King Shao.

Running out like crazy, trotting back cautiously, for fear of damaging the expensive saltpeter - for a child who grew up in a vegetable town, catching medicine is a luxury.

When the saltpeter arrived, Li Chongrun took a clean copper basin, put saltpeter in it, and waited for the reaction.

"Not enough?" After not seeing ice cubes for a long time, Li Chongrun understood that this was because there was more water and less saltpeter.

Indeed, if saltpeter freezes when it enters the water, there is no need to wait for future generations to discover it.

Saltpeter was added slowly until nearly a tenth of the saltpeter was used and finally froze in the basin.

"Alas, it's not enough......" Li Chongrun was numb.

Half of the saltpeter in the entire Shenjing Pharmacy is only one-tenth enough for a pot of ice, how many people are enough for this?

In fact, some corners of Shenjing can naturally condense saltpeter, the principle Li Chongrun is not clear, but he doesn't dare to use it, and he always feels unhygienic.

"I remember that there was a cooling displacement method, which could extract the saltpeter in the water and use it repeatedly." Li Chongrun pondered.

Saltpeter icing, which was really used in history, was at the end of the Tang Dynasty, and no one has really discovered it yet.

At that time, ordinary gunpowder also appeared, but the power could not end the era of cold weapons.

Li Chongrun called the old alchemist and informed the old alchemist of the cooling and replacement method, and asked him to teach his disciples to use saltpeter to make ice repeatedly.

The old alchemist is also well-informed, but he is also surprised by this pot of ice.

The general of the left guard squeezed away the children who were screaming around the copper basin, grabbed a piece of crushed ice with chopsticks, and put it in his mouth.

"It's really cold, and it's chilly." After the general left guard finished speaking, he didn't touch it again.

At this time, in Ziwei Palace, there are few ice cellars, and the price of ice is ridiculously expensive.

Even if he knew that Li Chongrun didn't use too much effort to make ice cubes, he was reluctant to eat more.

On weekdays, he thinks it is very reasonable to eat some inexpensive things in Shao Wangfu, so he should be a reasonable reward for protecting Shao Wang, and happy water is that he knows that the cost is not high, and he has no reference object before.

This ice cube......

"You just destroyed the heavens." Li Chongrun distributed the coke in the pot to everyone present, and let him take the cup or bowl if there were not enough.

After a while, everyone was itching to look at the bubbling dark liquid in the cup.

This time, General Zuo Wei looked at Li Chongrun and wanted to see how he drank.

Li Chongrun sandwiched a small piece of ice cube and put it in the cup, waited for two or three seconds, and drank the contents of the cup in one gulp: "Cool!" ”

Seeing this, the others followed suit, and the general of the left guard followed the crowd and also sandwiched ice cubes.

It's a pity that there are too few, and each person can't get much, but there are still a lot of ice cubes.

"Grunt!" The sound of swallowing saliva came from outside the door.

Li Chongrun looked for prestige, but saw an obviously stunted girl, secretly hiding outside the door, poking out a little head to peek into the courtyard.

"Sister, what are you doing here?!" One of the children of the old Fangshi's disciples was ashamed and angry, and felt that his sister had disgraced him.

Just as the kid was about to step forward to get rid of his sister, Li Chongrun stood in front of him.

"Your Highness......" The kid was flustered when he saw Li Chongrun.

"She's your sister, why are you treating her with such an attitude?" Li Chongrun's voice was cold.

Now everyone has the meaning of giving birth to a male and inheriting the incense, so even a family can't afford to eat, and has three daughters who still want to have a son.

So many families, maybe only one son, but this younger son must have older sisters, or even many older sisters.

"Your Highness, I ......" The boy lowered his head, not knowing how to react.

The thin girl outside the door hurriedly rushed in, and kept apologizing to Li Chongrun for her younger brother, and took the fault on herself.

Li Chongrun didn't blame her, but said to all the children: "Eldest sister is like a mother, she is one of the people who love you the most, you must not be ashamed of her, otherwise, you are the real shameful person." ”

In this era, even if the female emperor Wu Zetian is in power, there is still an atmosphere of male superiority and inferiority of women, of course, there are very few individual cases such as sons-in-law, and even more.

During the Wu and Zhou periods, the women of large families, especially the military generals, were ambitious.

General Zuowei even revealed to Li Chongrun that there was a female official in Zuowei who had boasted about the appearance of her predecessor in public, and felt that if she was looking for a son-in-law, she would recruit someone like this.

Li Chongrun had a crush, and asked rhetorically at the time: "What does the female official look like?" ”

"Very powerful, the shoulders are thicker than my waist......" General Zuowei's aesthetic is strange.

Don't talk far.

was educated by Li Chongrun, and the child suddenly woke up and apologized to the eldest sister.

"It's okay, I don't blame you!" touched his brother's forehead and wiped his tears for him, this girl was so well-behaved that it made people feel distressed.

Li Chongrun looked at the old man: "I don't believe that there are no girls who want to learn these things, are you confiscating them?" ”

"Master, there is indeed a reason why I don't accept it, but there are also people in the vegetable market who think that girls should not be like this, they don't want their daughters to show their heads, and they don't want them to get involved in these things...... "Old Fang Shi bowed his head, he is now a disciple, and he can't say that Shizun is wrong, then he is wrong."

Even if Wu Zetian tried to reform the concept of men and women for nearly 50 years, and his reign for ten years deepened the fact that women are not inferior, is it so difficult?

Li Chongrun frowned.

He used one of the most acceptable ideas of this era: "Then I tell you, everything I have learned to refine the elixir, what I have learned to make ice, everything I have learned, have been obtained in a dream journey, where there is no distinction between men and women. ”

"Women can hold up half the sky, they can fly to the ground, they can make mountains and rivers give way to make roads, they can become famous doctors, they can become teachers, they can enter the court as officials, and even more than one female ruler......"
