"Copies? And ice in the official's share? ”

Yan Yunzhou remembered that the person next to him didn't even know how many officials he was, looked at him and came over, raised his hand and pinched his face:

"Yes, from next month until September, depending on the grade, you can get ice, and there are many examples of our Hou Ye."

Ning Yi grabbed Yan Yunzhou's hand:

"That means if it's hot before June or after September, there's no use for ice, right?"

Yan Yunzhou smiled, and he didn't know why he was so obsessed with ice:

"If you hadn't used it six months ago, what would you use now? Rest assured, it won't be short of your ice. ”

Ning Ji's eyes lit up when he thought of something:

"I know, you have an ice cellar, if an official who doesn't have an ice cellar wants to use ice at home, he can only wait for a share, if the family has a large population, this ice may not be enough?"

"Well, most of them should not be enough, just like those who have many concubines, and those who can get ice are favored."

Although Yan Yunzhou did not have a concubine, he was still clear about the situation in the official's family.

"Isn't the treasury short of silver? Isn't this ice sellable? ”

Yan Yunzhou smiled:

"An ice cellar will not store too much, enough for a house is good, there is a largest ice cellar in the north of the city, and the ice stored every year is just enough for three months of ice, and the royal ice cellar has another ice cellar, how can there be so much excess to sell?"

Ning seems to have found a business opportunity:

"And what if I could make ice? Is it possible to sell it for money? ”

Yan Yunzhou thought of what Ning Ji had done in the past that he hadn't seen before, but he didn't doubt his words too much, but he still repeated:

"You know how to make ice?"

Ning Ji suddenly stood up and asked:

"Is there saltpeter around here?"

Yan Yunzhou was stunned for a moment, and he didn't know why he suddenly mentioned saltpeter, but Ning Qi glanced at him:

"What? The prince wants to lock me up again, can't you? ”

Seeing that he mentioned the old accounts from the past, Yan Yunzhou took his hand and quickly admitted his mistake:

"It was me who was wrong before, there should be some in the warehouse behind the saltpeter, not much, what are you going to do?"

Ning Qi didn't answer him, but directly called Dark Xuan in:

"Dark Xuan, you go and get some saltpeter, get more, and then find a basin, it needs to be so big."

Dark Xuan immediately went to order, and after a while, everything was ready, and Ning Xuan turned his head:

"Let's go, my lord, let me see a magical thing."

He went to help Yan Yunzhou get up, the man smiled, but he also got up with him, Ning Ji sent everyone down when he arrived in the courtyard, except for the two of them, only the dark Xuan was left in the courtyard, Yan Yunzhou sat in the chair in the courtyard and didn't know what he was going to do, Ning Ji smiled:

"Wait a minute."

Ning Qi filled the basin in Dark Xuan's hand with water, and then put a bag of saltpeter in an empty fish tank with blue and white porcelain that was much larger than the pot, and then put the basin filled with water in the water tank and let it float on the water, Yan Yunzhou was a little inexplicable:

"What is this doing?"

"You'll find out in a moment."

At this time, it was already dark, and it was not so hot outside, this courtyard was a place to enjoy the shade, and there were no mosquitoes in the courtyard with incense, Ning Zhi sat with Yan Yunzhou and chatted casually, and went to the water tank from time to time to take a look, and it didn't take long for Dark Xuan's eyes to widen:

"Is this water frozen?"

Yan Yunzhou turned his head in surprise, and supported the armrest with his hand, but the rattan chair was too low, and he didn't stand up with a pain in his knees, so Ning Ji hurriedly helped his waist and back, and half hugged the person to get up:

"Slow down, my leg hurts."

Yan Yunzhou came to the water tank, and the water in the basin was already frozen at the moment, and he suddenly looked at Ning Qi:

"This?"

Ning Ji crossed his arms and smiled:

"Simple, right? In a moment, this ice ballast will turn into a whole block of ice. ”

Yan Yunzhou was also stunned at this scene, he reached out to the water tank, and the water that was still a little lukewarm was now very cold:

"Because of saltpeter?"

Just now, he looked at Ning Zhi and just added saltpeter to the water tank.

"Yes, the main ingredient of this saltpeter is potassium nitrate, and when potassium nitrate is dissolved in this water, it will absorb a lot of heat to the surroundings, and the water and the water in the basin will be cold and freeze."

Yan Yunzhou also felt that the scene in front of him was indeed a little magical:

"As long as there's enough saltpeter, you can always make ice this way?"

"Yes, in theory."

Ning Qi helped the person back to the room, the room was already cooler because of the ice, Ning Qi was comfortable, but Yan Yunzhou's joints couldn't stand it, he covered people with a thin velvet blanket, and then sat down beside him again, and said with a straight voice:

"Remember the equations I wrote when I was making medicine for you?"

"Are you talking about the alphabet?"

Ning Ji smiled and nodded:

"That's right, the reason why the kind of gunpowder made by Qingyang Dao people uses saltpeter, in fact, the main thing used is the ingredient called potassium nitrate, potassium nitrate has many uses, it is mixed with sulfur and carbon is the so-called black powder, dissolved in water can be used to make ice, and then with excess aqueous solution, it can also be precipitated to precipitate relatively pure potassium nitrate for gunpowder production."

This is indeed a good method, but it is also very dangerous, Yan Yunzhou raised his eyebrows slightly:

"This method can only be in the hands of the imperial court, and even, it must be in the hands of the emperor, when we return to the palace, let's report to Your Majesty in detail, if it is feasible, it is a method to fill the treasury."

Ning Yi also knows that it is powerful, this is just an ordinary chemical reaction in modern times, but this is ancient times, and if you want to fight for power, it is nothing more than soldiers and money, and these two things are naturally the safest in the hands of the emperor.

"I understand, the rest is up to you, okay, it's so late, go to sleep."

Yan Yunzhou sat on the edge of the couch and looked at the quilt:

"Is the quilt thick, I'll ask someone to change it to a thinner one for you."

"Is there a thin one?"

Yan Yunzhou ordered someone to change his bed, and Ning Yi touched the thin and light quilt, which was as soft as cotton:

"So comfortable? What is it made of? ”

"Silk."

Ning Qi hurriedly lay on the bed and felt it, he had no doubt that the silk quilt here was definitely more elaborate than the tens of thousands bought in modern times, it was light, thin and breathable, and it could even be embroidered with flowers, which was simply a work of art:

"I'll build this this summer, I'll sleep outside, it's hot inside."

Yan Yunzhou naturally has no opinion:

"Well, Master Hou can sleep wherever he wants."

The two of them only left one lamp, there was still some ice left, and the room was not so hot, Ning was quite comfortable covered with a high-quality silk quilt, and suddenly remembered someone with his eyes closed:

"By the way, what about that old thing?"

When he died, Xuanwei was still on the front line with the army, and he didn't return to the capital at all, such a person who had pit him again and again, he didn't even see his end when he arrived, and after being quiet for a long time, a slightly low voice sounded beside him:

"Ling Chi, I was imprisoned."

Ning Ji suddenly opened his eyes, Ling Chi? Is it the Ling Chi he thought? He turned around and met the man's deep eyes, and before he could speak, he heard Yan Yunzhou continue to speak:

"And the person who shot you, beheaded, is also my prison."

Ning Qi pursed his lips slightly, he was too far away from such a criminal law, and just subconsciously made a voice:

"Ahh

Yan Yunzhou closed his eyes in the dim tent, and reached out to wrap his arms around Ning Ji's waist, he never opened his eyes, he was afraid that Ning Ji would see his cruelty, but after all, he couldn't help but explain:

"The two armies are facing each other, and life and death are supposed to be their own destiny, but, Yu'an, I am not a saint after all."

Xuanwei was ordered by Li Yan personally, but the general who shot Ning Ji was Yan Yunzhou who insisted on cutting him in half, and he has no regrets until now, killing what he loves, cutting him in half, is the best ending he can give him, becoming a king and defeating him, if he is defeated, he will also let others deal with it.

Ning Yi kissed Yan Yunzhou's cheek and slowly came to his lips, unlike the stormy kiss before, this time the kiss was very gentle, with endless tenderness and comfort:

"I know, none of us are saints, and if it were you who had an accident, I would have gone crazy."

He remembered that time when Yan Yunzhou was carried back to the camp tent, at that moment, he really wanted to bombard all the people on the other side, and any morality and reason obeyed the laws of the battlefield at that moment.

This night, Ning Yi slept with Yan Yunzhou in his arms, although he was very hot.

On the second day, when Ning Ji arrived at the Zhou family, he saw the second son of the Zhou family who went to court with him:

"Isn't this Lord Zhou? Are you there today? ”

In the past two days, the Zhou family can be regarded as being erected on the Flame Mountain, Zhou Qing went home that day and told his old man about the court, his father invited the house doctor that night, and several of the Zhou family's official positions were almost in his father's study for the past two days.

Zhou Muchang can be regarded as having gone through three dynasties, but it is not really unstable, Zhou Qing now remembers that day in the study that his father seemed to suddenly be several years old, Zhou Muchang looked at the big family in front of him, and his hair seemed to be a lot whiter than before:

"My Zhou family and today are also considered a powerful family, although today's Majesty is young, but there is quite a strategy in his chest, Yan Yunzhou took over the prince from his father and brother, commanding the northern army, in those years, how many people in the court wanted to put him to death, he hid in the past, and even, he supported the new emperor to ascend the throne, looking at the current situation, His Majesty relied on him to trust him far more than to guard.

Although the Marquis of Ning has never seen it as a father, but just because he has only been to the court once, he has pulled our entire Zhou family down, and he is stronger than any of you, the new emperor ascended the throne, the treasury is empty, and Your Majesty has already made up his mind to clear the land to fill the treasury. ”

"Father, then we... Why did he focus on our Zhou family? ”

Zhou Muchang looked at his son who was still unenlightened, and snorted:

"Why? Because you were aggressive, that Ning Hou took out Yan Yunzhou's fold in the court, who made you uncontrollable? ”

The emperor wants to take this opportunity to show his determination to clear the land, he will not take ordinary people, he must be the power of the dynasty, although he is ranked second, but he is also a veteran of the three dynasties, and the Zhou family is quite a good candidate.

"The matter has come to this, it is useless to say more, Yan Yunzhou dares to go to the fold, the Yan family will definitely do their best to cooperate with the household department, when the time comes, if the Zhou family has half a point of concealment and prevarication, what is waiting for is the catastrophe, Zhou Qing, Zhou Chong, you both will go to Zhuangzi tomorrow, and there must be no half point of prevarication in the household inventory, when the family was divided in the past, your second uncle and third uncle's land has been divided, and you don't have to worry about the bad debts in the back.

If it is Your Majesty's grace, I can also give a tribute, if not, the Zhou family will not lose everything. ”

Zhou Qing thought of his father's words, and didn't dare to be disrespectful to Ning Ji:

"Master Hou, polite, this is my third brother Zhou Chong."

There are contacts and contacts, but Ning blame also returned the courtesy.

This day really made Yan Yunzhou right, the Zhou family didn't dare to hide it at all, the day went very smoothly, and when he returned to the courtyard in the evening, he joked:

"Our prince is really clever, why are you sure that the Zhou family doesn't dare to make a small move this time?"
