The control group of the ancient heroine

Yang Haiyan knows whether boiling water can produce saltpeter, but you can try it. Yang Haiyan has been thinking about how to try it out. For example, after the ice melted, did you boil the water incorrectly?

This worked, and soon, Yang Haiyan had other ideas.

Qin Fang was in high spirits and was in particularly good spirits: "Yanyan, go to bed first and then write a letter to Du Da그 and tell him how to make ice with saltpeter."

Yang Haiyan said: "Okay. By the way, Mr. Du, why do you always write letters to Du Da그, but 놊 directly submit the memorial to the emperor?"

Qin Fang's own thoughts: "I first entered the court. I came from the imperial examination and knew many of the rules of the court. I had gotten along with Du Da그. I thought Du Da그 was a good official, so I If you write a letter to him, he should remind him if he feels it is appropriate. Secondly, since he is a military commander, there is no problem in theory if the military commander’s memorial comes to the Ministry of War first.”

Yang Haiyan has read the laws of Qi State. Qi State did not have a cabinet, so unlike many dynasties, many dynasties had cabinets. Therefore, official memorials would first go to the cabinet, and then the cabinet would select and submit them to the emperor. In this case, The cabinet first read the memorial. Then, if the cabinet minister and the official who wrote the memorial confronted each other, the memorial might be suppressed.

‌Of course, official memorials will be transcribed and registered before submission.

Another way is for the officials to hand over the memorial to the emperor privately, which would cause trouble to the palace officials.

However, although some dynasties did not have a cabinet, there was another way to submit memorials. It is the department of the imperial court that collects memorials, called the General Affairs Department. The General Affairs Department then sends them to the palace, where they are handed over to the officials in charge of the palace, and then presented to the emperor's table.

In Qi State, memorials by civil servants and memorials by generals were separated. The memorials of civil servants were delivered directly to the Secretary of General Affairs, who then delivered them to the palace, and then to the emperor by the palace officials. Memorials from generals usually arrive at the Ministry of War first. Of course, if the general wants to submit the memorial to the Ministry of War, he can also submit it directly to the General Affairs Department.

But as a result, the Ministry of War would be a little embarrassed. For example, the emperor knew about these situations, but the Ministry of War knew about them. When the emperor asked questions in the morning, the officials of the Ministry of War were passive. It is also possible that the officials of the Ministry of War will hate the generals for this. For generals, this is not beneficial.

Moreover, if the Ministry of War knows about some situations related to the Ministry of War in advance, it will also be conducive to the adjustment of the Ministry of War.

However, Qin Fang gave the memorial to Du Ke first, but because of this, he completely wanted to find someone to lean on and hug his thighs. He knew that he was soft-spoken and understood all these things. He hoped that Du Ke Give him some pointers. Du Ke is the Minister of War. Even if Qin Fang knows the affairs of the imperial court, he also knows that the Minister of War can be anything. Especially when the new emperor ascends the throne, what he wants to control is the military power, so the Minister of War must be him. 그.

Qin Fang would tell Yang Haiyan about some of his dark thoughts. He wanted his wife to know some of his calculating thoughts. It was all when he had nothing, when he was down, and when he was literate. She came with her, he didn't care that in front of her, he had been poor, but he cared that in front of her, he was perfect, with many shortcomings. Yes, he just wanted her to know about his conspiracies.

Qin Fang wrote the memorial overnight, and at dawn the next day, he sent it to the capital.

So two and a half days later, Du Dajin received Qin Fang's second letter.

Du Ke was now in the imperial study room, looking at the emperor face to face. Du Ke just walked out of here half an hour ago, and the monarch and his ministers had discussed the rewards for Qin Fang and Yang Haiyan. Unexpectedly, half an hour later, Qin Fang sent him a piece of work, making ice with saltpeter. If Qin Fang dares to tell this, then saltpeter must be able to make ice.

The Emperor: "Sulfur mines, saltpeter mines, military camp fields, saltpeter ice making, all these things happened on the second day after I ascended the throne. Du Ke, tell me, this Qin Fang is really My lucky star. "Things that benefit the country and the people happened when he ascended the throne. No emperor would like such good things.

Du Ke was startled and remembered what his father said just today. His father said that Qin Fang's mistake was due to luck.

And the emperor really likes this kind of luck. Especially for someone like Qin Fang, who was born in a poor family, has no support, and no family. No matter how lucky he is, no matter how high he is promoted, he is still afraid of doing bad things.

The emperor said: "In March, it rained continuously for half a month, the dam collapsed, and the floods flooded. Everyone said that my throne was well-deserved. This way, Qin Fang suppressed the bandits and sent Money has come. Tell me, if when I ascended the throne, I had produced firecrackers, solved the food problem for millions of soldiers in the military camp, and solved the problem of having to use more ice than even my family, who would say anything? , My royal title is just right, and it has attracted God’s punishment?”

Du Ke lowered his head and dared to speak.

The emperor laughed loudly: "Qin Fang was wrong, and so was his wife. You are right, this is a marriage involving me, and I am their elder brother."

Duco: If you say yes, then it is.

The Emperor: "Come, let the Imperial Hospital bring some saltpeter. Let's try following Qin Fang's method of using saltpeter to make ice. If it really works, the price of ice will drop, and people may be able to afford it. I'm sorry, sir. After all, it would be really..."

Du Ke: "The emperor is wise and wise, so it will definitely be possible."

The emperor had heard too much flattery like this: "Unfortunately, no matter how big the saltpeter mine is, there is no limit. If the saltpeter mine is dug out, there will be no saltpeter to make ice, and the ice will still..."

Du Ke said: "Maybe the beast Qin Fang mentioned is only a saltpeter mine."

The Emperor: "Even if it's two places or three places, that's also limited."

After a while, the imperial doctor came with saltpeter, and brought enough saltpeter according to the emperor's abundance. Because saltpeter is slightly poisonous, the imperial doctor came in person.

When the imperial doctor arrived, a large basin and a small basin were placed in the royal study room. Water was put in both basins, and the small basin was placed in the big basin.

The Emperor: "Put the saltpeter into the big basin so that it touches the small basin."

Eunuch: "Yes."

Imperial Physician: "Your Majesty, please forgive me for your boldness. Saltpeter is poisonous. I have to abuse it without the doctor's instructions. Do you know what your Majesty wants?"

The emperor had listened to the imperial physician's words in the past. After all, it was related to his own body. But today he also wanted to show off in front of the imperial physician: "This saltpeter has uses you know, so just watch it..." …Put more saltpeter in the big basin.”

Eunuch: "Yes."

Since the emperor said this, the imperial doctor naturally looked at it. However, the reaction of saltpeter in absorbing heat and cooling down was very fast. Because enough saltpeter was put in, the water in the basin started to become cold after half an hour. 놊It's just air-conditioning, but it's far from freezing.

Both eyes of the imperial doctor lit up: "Your Majesty, what is this?" The imperial doctor was slightly shocked. As an imperial physician, he dared to say that he read a lot of books. He had read most of the books related to medical skills, but he had never known that saltpeter was so useful.

When the emperor saw this, he laughed again. It can be seen from the laughter that he is in a good mood today: "Qiu Aiqing, it is said that saltpeter is poisonous. If you put it in water to make ice, the ice produced will also be poisonous. This is how you make ice by separating water. In a small basin Ice is non-toxic and edible, do you think so?”

Doctor Qiu: "We have to let Wei Chen check it." It is very simple to check whether the water-proof ice-making machine is poisonous or edible. As long as the cold water is non-toxic, then it will naturally be non-toxic if it turns into ice.

So soon, Imperial Physician Qiu came to the conclusion: "Your Majesty, as you just said, making ice through water is indeed non-toxic, but the water in this big basin is poisonous because too much saltpeter is put in, which speeds up the cooling. speed, so the toxicity is stronger than the saltpeter itself. "

The Emperor: "That is to say, if the Ministry of Industry can design good ice-making vessels, it is possible to use saltpeter to make safe and edible ice."

Doctor Qiu: "Yes."

The emperor sighed: "It's a pity. The amount of saltpeter is limited, and the ice that can be made is also limited."

Doctor Qiu thought: "That's not necessarily true. Maybe saltpeter can be used repeatedly, but I haven't verified it yet. Wei Chen is sure."

When the emperor heard this, he asked excitedly: "What do you think of this?"

Dr. Qiu said: "Cook. The saltpeter melts in the water. Boiling the water may produce the saltpeter."

Duco: "What do you mean?"

Doctor Qiu thought for a while, took out a white handkerchief, took out a bottle of potion, poured the potion on the handkerchief, and then explained: "Have your Majesty and Doctor Du ever heard of boiling medicine? This potion is poured on If the scarf is dry, you can put the scarf in a pot with water and boil the potion on the scarf. If the saltpeter is dissolved in the water, the saltpeter should be boiled out. If it can really be cooked, saltpeter ice can be used repeatedly.”

The Emperor: "Then the ice will be valuable, and the common people can afford it." Although the ice manufacturers lost their profits, in the Emperor's heart, the common people were naturally more important.

If Yang Haiyan were here at this time, she would definitely be excited when she heard what Doctor Qiu said. The wisdom of 녢그 is really incredible.

The emperor said: "In this case, the matter of boiling saltpeter will be left to you. Remember, this matter must be spread."

Doctor Qiu: "I obey the order."

The emperor nodded: "You can go out now." He ordered the eunuch, "Help Doctor Qiu move these things to the Imperial Hospital."

Imperial physician: "Yes."

Doctor Qiu: "Thank you, Your Majesty."

Du Ke came in the afternoon, and it was already past dinner time, and it was getting dark, so after verifying the matter of making ice with saltpeter, he said: "Your Majesty, it's getting dark early, and it's time for me to leave. "

The Emperor: "I'm sorry, please stay in the palace and have dinner with me."
