"An Pingjun is back?"

In the Proton Mansion, Mingyue was a little stunned. Pen, fun, pavilion www. biquge。 info

At this time, it was late May, and he had been in Qi Country for more than two months, and he had fully adapted to life here. But with the arrival of midsummer, Mingyue discovered that the heat in the north of this era was even worse than that of later generations, the temperature was higher and higher day by day, and mosquitoes and flies were breeding on the edge of the pond in Proton Mansion.

So he was only wearing a thin cicada robe at the moment, and as usual, he stayed in the sorcerer's room that he personally named "Laboratory", and the entire Proton Mansion and outside, I am afraid that it was surprisingly cool here.

However, this kind of cozy coolness was soon broken by the news of Anping Juntiandan's return, and Mingyue pulled Li Tan, who reported the matter, and said, "Why didn't I hear a little news from Housheng in advance?" An Pingjun can be regarded as a triumphant return, isn't there the prince's outskirts to greet him and the city gate to boast? ”

Li Tan is smarter than the rangers, and has learned Linzi dialect, so Mingyue let him take a few people to go out to the city often to inquire about the news in the market, in this era of difficult information transmission, a broad source of information is necessary.

Sure enough, when Li Tan was wandering around the city, he saw the scene of An Pingjun returning to Linzi and entering the palace from Yongmen to meet King Qi.

Li Tan said: "I also knocked on the side to inquire, and heard that An Pingjun has never liked publicity, every time he goes out to lead the army to fight, he always pulls the army to the barracks first, and after the completion of the settlement with the Wudu military captain, he takes the tiger talisman and enters the palace alone to restore his life. ”

"This is avoiding suspicion, this An Pingjun is really cautious."

Mingyue couldn't help but sigh, how could Tian Dan not know that he was jealous and suspicious of King Qi? Although the monarch and ministers had reconciled under the coordination of Ermine Bo, the king of Qi Tian Fazhang was still nervous, and Tian Dan's actions became more and more careful to avoid the fact that he was loved by the Qi people to irritate the king of Qi again.

Not only did he hand over his military power immediately after the battle without delay, but in previous years in Linzi, Tian Dan also lived in a simple place, avoiding traveling with other ministers, and his own fiefdom Yeyi had not been inspected once......

Tian Dan was able to work with the King of Qi for more than ten years, and did not make a tragedy of the cunning rabbit and the death of the lackey, or the tragedy of the ministers killing the king, it is true that the Qi State has no other pillars and can only rely on Tian Dan, and because he has no ambition, he is cautious......

"An Pingjun is a true loyal minister of the Qi State." Mingyue still hasn't said half a sentence, that is, this balance, as King Qi's illness becomes more and more serious, I am afraid it will be broken, with Tian Fazhang's extremely heavy suspicion, can he rest assured that the orphans, widows and the entire Qi country will be entrusted to Tian Dan?

As soon as he thought of this, he thought about going to Anpingjun's mansion to visit another day, firstly, to go online with Tian Dan, and secondly, to know, who was Anpingjun's beautiful young lady who often accompanied him to Jixia School Palace, who was the woman dressed as a man and thought that he didn't see it......

How can there be no gifts for the visit, he brought several carts of money and silk when he came from Handan, but Mingyue was afraid of the treasured treasures, and he would not accept it with the caution of Tiandan, and turned to look at the busy magicians and apprentices in the Dan room, but he had an idea.

"Mr. Xu, Lu Sheng, you and the others will work harder and make more ice!"

……

Fang Warlock Xu Ping was originally squatting on the edge of the big groove called "Hua Chi", carefully observing the reaction that was quietly happening inside, and when he heard this, he immediately cried bitterly.

He complained: "Childe, not to mention that it is extremely difficult to find and eliminate stones, and it is not easy to make ice with stones, our master and apprentice have been groping for several days to become proficient, how can we say that there is one, my apprentice, do you say yes." ”

Unexpectedly, his apprentice Lu Sheng rebelled against the camp, and stood beside Chang Anjun with a face full of admiration and said: "Master, it's not too dirty and bitter for me to take the young people in the house to scrape nitrate in the toilet, you just purify it, add it to the water and wait for it to freeze, what kind of bitterness is it?" ”

In the past two months, the little apprentice Lu Sheng has increasingly deviated from their original intention of alchemy and seeking immortality, and has taken refuge in Chang'anjun's strange sayings, what boiling point and freezing point, and he is more skilled than Xu Ping, believing in this, thinking that it is the truth between heaven and earth.

Xu Ping was speechless, his heart was sour, but he was also accustomed to the privileged life in the Proton Mansion, although what Chang Anjun wanted was all strange things, far from his "elixir of life", but it had a lot of fun.

After distilling soju and then purifying "alcohol", Chang'anjun arranged a new job for them, that is, to purify the "eliminated stone" purchased on the market.

This thing Xu Ping is familiar with, the stone is the saltpeter of later generations, this thing has been discovered in the spring and autumn period, after the rise of alchemy, Yan Qi Fangshi attaches great importance to it, and constantly explores its nature, saying that it is "born of the gas of the sea halogen, and it is the thing of heaven and earth to the gods,...... It can make seventy-two petrified and turn into water, soften the hardware, and refine the eight stones, although the Great Dan is not willing to give up."

In alchemy, in addition to the usual "fire method", there is also a set of "water method", which is to use saltpeter as raw material.

Xu Ping was suddenly excited, thinking that Chang Anjun was finally going to let them do some of the magician's own work.

Unexpectedly, Chang Anjun was still not interested in taking mineral poisons, but instead demonstrated to the magician master and apprentice a thing that seemed to them to be amazing......

Chang'anjun asked them to take a large plate, put water in the plate, and put a copper pot filled with half a jar of water in the plate, and constantly added saltpeter to the plate, and the saltpeter melted when it met the water, and the room suddenly had a trace of coolness, and as a result, half an hour later, the water in the tank became a hard ice......

"It's ...... Ice? ”

Xu Ping and Lu Sheng were dumbfounded, and they were shocked by Chang'an Jun for a while, you must know that this is the midsummer of May, and turning water into ice cubes in the summer is simply amazing! Even the best magicians can't do it.

Chang Anjun shook his head, and pierced the mystery of this reaction with one word.

"Remember what I told you about the freezing point? If the ambient temperature drops below freezing, the water will turn into ice. When this stone is dissolved in water, it will absorb a lot of heat, so that the water temperature will be lowered, and the cold on the outer plate will be transmitted to the copper pot, below zero, the water in the tank will naturally condense into ice, which is the same as the principle of freezing in winter, which is not surprising. ”

The master and apprentice of the magician looked at each other, ashamed to say that although they had also owned a small amount of saltpeter for alchemy in the past, the amount was too small, and it was impossible to add it to the water to see the changes.

The ice water on the outside dish is poisonous, and if you eat it, you will definitely vomit and diarrhea, but it is edible in the copper pot. At that time, Chang Anjun took the lead and put it in his mouth and chewed it, and Lu Sheng also learned from him to take a small piece of ice and put it in his mouth, and suddenly a cool and comfortable feeling from the tip of his tongue to his throat and then to his lungs, driving away the scorching summer day, making his pores all over his body comfortable.

Then the boy wiped his tears and wept: "Master, I can't imagine that I can live a life of drinking ice in the middle of summer. ”

Xu Ping's face was full of shame, indeed, in this era, drinking ice in summer is something that can only be enjoyed by wealthy families.

There is a saying in the Book of Songs, "The second day is to dig the ice and rush, and the third day is in Lingyin", which means that the ice is chiseled in December of the summer calendar, and the ice is hidden in the ice cellar in the first month for summer use. The ice cellar is similar to the cellar, which is built underground with stone, but due to the small stock and high cost, it is generally only the princes of the Son of Heaven who can afford it, and a special position is set up to be responsible for this matter, called "Iceman", who slashes ice and Qiling.

In the summer, the iceman regularly takes ice from the ice cellar and distributes it to the doctor as a gift, Mingyue knows that there is an almanac called "Xia Xiaozheng", which specifically talks about the matter of "awarding ice", and there is a custom of sacrificing lambs when awarding ice, which shows the importance of this matter.

So the nobles happily went home with ice, and then used ice cubes to chill food and wine, enjoyed with their wives and children, and sat on the high platform to watch the common people sweat profusely under the hot sun......

Therefore, the popsicles that ordinary primary school students in later generations could enjoy for five cents were already the privilege of Wang Sun Guizhou in ancient times......

It's no wonder that Lu Sheng cried so excitedly after tasting the ice.

There is also an ice cellar in the Proton Mansion, but there is no stock, and Nuqi feels sorry for Chang'anjun's unbearable heat, and reminds him that he can ask the royal family for it. But the confessor Hou Sheng said that because Linzi was extremely hot this year, after entering May, even the ice in the royal ice cellar melted one after another, and there was no ice in the entire Linzi, and the king of Qi and the crown prince were too hot to help, so he couldn't help.

Nuqi was a little helpless, but Chang Anjun smiled and said that it was okay, and then took the magician in the Dan room to make ice by himself, and in the next few days, Nuqi was pleasantly surprised to eat the "shaved ice" with honey.

After saltpeter is dissolved into water, it can be reused by cooling crystallization method or evaporation crystallization, so Mingyue not only wants to meet her own needs, but also plans to take it out as a summer gift......

"In the palace, the Queen Mother of Qi and the crown prince will send a total of three copies, Housheng will send one, Anping Junfu will send one, and Jixia Xuegong will send one each, and the three gentlemen Xun, Zou and Gongsun Long will also send one each......"

As a civil servant in her previous life, Mingyue deeply knew a truth, communication does not rely on natural familiarity, nor on one or two first-sight acquaintances, but on the continuous accumulation of human contacts, and after a few times, she is familiar with it.

But in this way, not only was the magician tired enough, but even the saltpeter was not enough.

"It's so rare." Seeing that the output of ice was far less than the demand, Mingyue couldn't help but sigh.

Except for a few natural saltpeter mines, this thing can only be scraped in the mud of dry corners, toilets, and pigsties, and then filtered and purified.

He couldn't help but say to Xu Ping, who had always felt that he was not doing his job to make ice with saltpeter: "Ice making is just incidental, the real use of saltpeter, I will teach you and others in the future, Mr. knows where in the world is the most saltpeter?" ”

Xu Ping replied to him with a desperate message.

"I only know that most of the saltpeter in the hands of the warlocks in the world was purchased from the Qin State, and it is said that there is a large nitrate mine in the middle county of Qin and Hanzhong, which is inexhaustible......"

"Qin State, Hanzhong County ......" Mingyue rolled her eyes: "Qin State forbids foreign businessmen, and if you want to transport this thing out of Qin in large quantities, it is more difficult than ascending to the sky, it seems that within ten or twenty years, there will be no play." Alas, if only there was a great lake in this world where saltpeter was produced in the same way that salt was produced in the reconciled pool......"

Xu Ping looked at him strangely: "Don't you know Chang'anjun?" ”

Mingyue was stunned: "What?" ”

"Taiyuan County of Zhao State was formerly known as Dalu, there are countless lakes, Zhaoyu Qi has been surging so far, but some small lakes have dried up, and some lake beds produce salt, which is mixed with saltpeter, although it is not as much as Hanzhong, but there are also many ......"
