The Hou Mansion fell to His Majesty, he followed me during this time and offended the one in the palace, if there is a radical change in the world in the future, I will not worry about him, you follow him, stay in Youzhou, King Jingjun will definitely take care of it. ”

Dark Xuan's eyes were red, and Yan Yunzhou kept looking at him until he nodded.

"Okay, let's go, don't have any pressure, this king won't die tomorrow, go and call Li Han and a few people over."

Because Ning Qi didn't know how to ride a horse, so when he went to Montenegro this morning, Yan Yunzhou specially ordered someone to drive over, but fortunately, there was a small road to walk on the side of Montenegro, and the Qingyang Dao people naturally followed Ning Ji to rub the car once.

"Oh, it's still comfortable to ride in this car."

Qingyang Daoist very unceremoniously occupied half of the frame, and Ning Ji took a piece of paper in his hand, which was the process he had just sorted out.

Among them, the most likely method he can think of is to use hydrogen chloride gas and sulfur trioxide gas to prepare it, and almost all of these gases need to be obtained with concentrated sulfuric acid and concentrated hydrochloric acid.

Concentrated sulfuric acid and concentrated hydrochloric acid are definitely the C position on the test bench in modern laboratories, but they are not good now.

But he can't do it, it doesn't mean that the Qingyang Daoist in front of him can't do it, this person can give the first emperor the pill that he doesn't have, he must have some research on alchemy, and sulfuric acid was made by the alchemy Taoist in history.

"Qingyang Daoist, ask you for something."

Before Ning Jiao set off today, Yan Yunzhou was afraid that he would be hungry, so he deliberately asked people to put some food on the frame, and at this moment, it was not Ning Qi who ate on the table last time, but the old man with a sheep's beard:

"Childe said this, I have a breeze on my sleeves, how can I have something for you?"

Ning Qi's time in the past two days can also be seen, this Qingyang Daoist is a slippery and somewhat transparent person, it is not easy for such a person to live to this day, he did not go around in circles, and spoke directly:

"Alum oil."

Qingyang Daoist raised his head this time, and the beard on his chin was still sticking to the scraps of snacks:

"What do you want alum oil for?"

Ning Ji heard his answer, and it was, 'What do you want alum oil for?' What is 'Alum Oil?' He knew there was a play right now:

"Give me alum oil, and I'll let you eat another roast venison."

Qingyang Daoren's little yellow bean blinked, alum oil is not precious, but it is worth changing a meal of roast venison:

"Okay."

Ning Yi was about to laugh out loud, he actually just asked with the mentality of giving it a try, the main ingredient of alum oil is actually sulfuric acid.

When he was in school, he remembered reading a miscellaneous note, which was about the alchemist Gu Gangzi refining alum oil, but he didn't expect that the alum oil of this era was also called this name, and with the alum oil, he could purify concentrated sulfuric acid.

With this most basic chemical agent, he can synthesize concentrated hydrochloric acid through concentrated sulfuric acid and salt synthesis, both of which have chlorosulfonic acid and are hopeful.

Ning was in a happy mood all the way because of the green alum oil.

After a while the frame stopped:

"Ning Gongzi, I can't get on the car, so I can only go up."

Ning Qi and Qingyang Daoren got out of the car, today is a cloudy day, although there is no big sun, but fortunately, it is not windy, Ning Qi squinted and looked at the mountain in front of him.

The awl type is indeed the most typical appearance of a typical volcanic eruption forming a volcano, but this black mountain should be called the White Mountain now, because the black mountain in this season has been covered with snow.

Yesterday, the place where the Qingyang Daoist came had been dug out of the surface soil by the soldiers, Ning Ji walked over and looked, the gray color, and there were many clods of soil, many of which were the soil stones containing sulfur that the Qingyang Daoist picked up yesterday, and there were a lot of yellow crystals in the middle, which was ammonium chloride.

Ning Ji hurried up and ordered with the soldiers who followed:

"Everyone's idea is to pick up as many hepars as you want."

There are many people and great strength, and the sulfur-containing soil and ore that Qingyang Dao people need, as well as the ammonium chloride that Ning Yao, are quickly filled with several large bags.

Ning Qi had a shovel in his hand, he wanted to see if there was anything else that could be used, he walked a little farther, and when he raised his eyes, he saw a black land, which was very obvious in a piece of white, but it was far away, and he couldn't see what was over there.

Then he turned to one of the soldiers on the side and asked:

"What's that darkness over there? Excavated? ”

The soldier grew up in the north, and looked at the opening:

"Oh, that's coal, it can make a fire, before the village moved away, I came here to dig coal and burn it back in winter, it is much more durable than firewood, and I put this thing in the stove, and the house can heat up for a night."

The soldier knew that Ning Qi was from the capital, and specially explained to him how good this thing was, but Ning Qi suddenly turned his head:

"It's called Black Mountain, isn't it not only the mountains that are black in summer, but also the places where there is this coal are black?"

The soldier nodded:

"yes, it's all black."

Ning Yi stood there with a shovel, squinting at the excavated land in the distance, so it was, he said, well, the volcanic ash is not pure black, how can it be called Black Mountain, it turns out that this is an open-pit coal mine.

He even laughed, the sun showed a ray of sunlight in the cloud city, and Ning Qi stood on a piece of white, not knowing whether he should feel the gift of nature.

When he came, he actually noticed that Wuzhou Mountain was a bit like the Taihang Mountain of his time, very barren, there was almost no tall vegetation on the mountain, and with so many garrisons in the north, heating in winter was a big problem.

The barrenness of the mountains meant that there was not enough firewood, but there was an open-pit coal mine that could be mined without much effort.

Moreover, with such readily available and abundant coal, it was possible for him to refine benzene from coal tar himself.

It will be half a day's journey to go back, so before it gets dark, Ning Ji has already followed the team back to Suizhou City, and the harvest of this day is not small, which directly leads to Ning Ji's good mood when he goes back.

When he went back, Yan Yunzhou had just come out of the conference hall, obviously sitting on his lap for a day, half of his body was leaning on Dark Xuan's body, and he smiled when he saw him:

"Coming back? Come in and warm up. ”

Ning Ji walked over and looked him up and down, Yan Yunzhou's complexion was very bad, so bad that he could see at a glance that his condition was not good, almost no need to ask, now he is afraid that there are few comfortable places on him:

"Done?"

"Well, I'm done."

Today, Yan Yunzhou called three generals and dismantled the recent battle plan in detail, Li Han has led the troops for many years, and he doesn't need to ask about the following matters one by one.

Ning Qi nodded:

"Let's go back to the room when you're done, it's time to change the medicine in your chest."

Ning Ji walked to his side and walked side by side with him to the residence, Yan Yunzhou didn't ask him what he had gained today, but he could see that he seemed to be in a good mood, looking at the soldiers coming and going, he also remembered something, and turned his head sideways to Ning Ji and said:

"You haven't learned to ride a horse yet, have you?"

"Well, I'm not available these days."

Since arriving in the north, Ning has not been idle, where is the time to learn to ride a horse?

Yan Yunzhou looked at the stable at the back of the yard, looked at Ning Ji and said with a smile:

"Then tomorrow, I'll teach you tomorrow morning."

Ning Ji remembered that on the way here, this person said that he would go to the north to teach him to ride a horse and learn to ride a horse? Horseback riding is now almost an aristocratic discipline.

A 40-minute experience class costs a few hundred yuan, which is not very bad for him, but he has no time, and the horse farms in the modern city are not very big, and they are naturally incomparable to the vast north.

Who doesn't have a dream of riding a horse? To say that I don't want to learn is false, but Yan Yunzhou's body:

"How can you teach you to ride a horse? You can just show me a little soldier and teach me. ”

Yan Yunzhou is a little persistent in this matter:

"I promised to teach you when I came, don't worry, I'm very docile in lightning."

Ning Ji looked up, this man was going to teach him with his mount? He had seen that horse, and even he, a person who didn't understand horses, could see that it was very handsome, and he couldn't help but feel a little excited.

"Okay, that's settled."

Yan Yunzhou nodded lightly, there was a hint of complexity in his eyes, if he didn't have much time, this would be a little selfish on his part:

"Okay, it's decided."

The author has something to say:

In the end, it was the prince who was moved first

Chapter 49: The Last Selfishness

At night, Ning Qi was changing the dressing on Yan Yunzhou's chest, the weather in the north was cold, people hardly sweated, the wound healed quite well, there was no inflammation, redness and swelling, but the symptoms of Yan Yunzhou's pneumonia were relieved quite limitedly, and Ning Qi knew that this was because the effect of allicin was not enough.

Compared to last night's anxiety, after getting the alum oil today and knowing that this is an open-pit coal mine outside, Ning's tense mood has been relieved a little.

Although allicin can't completely cure Yan Yunzhou, it has played a role after all, although it is difficult to prepare sulfonamides, but now that he has a direction and raw materials, he doesn't believe that he can't do it.

"There's nothing wrong with the wound, I'll help you remove the stitches now, come, lie down."

Yan Yunzhou was helped by Ning Qi to lie flat on the couch, Ning Qi brought his medicine box, disinfected his hands and instruments with alcohol, and picked up tweezers and scissors.

His expression was focused on the wound on Yan Yunzhou's chest, and Yan Yunzhou could see his eyelashes fluttering like a small fan almost as soon as he lowered his eyes.

"Does it hurt?"

"It doesn't hurt."

Ning Qi's level of stitch removal was naturally no problem, and after a while, the thread was removed, and he smiled while holding the thread:

"Okay, get up, if the thread is removed, there won't be much of a problem on your wound, as for the situation of the lungs inside, we still use allicin first.

Although it can't be completely cured, it can always be relieved, the medicine I have in hand is already eyebrow-raising, don't worry, I said that I can save you. ”

With a firm confidence in his eyes when he spoke, his whole body seemed to glow, Yan Yunzhou raised his hand and buttoned his shirt and smiled:

"Is it Montenegro that has what you want?"

This man was still sitting on the edge of the table scratching his head last night, and it seems that he has gained a lot today.

Ning Yi disinfected and put away the instruments in his hand, and his spirit was a lot lighter:

"There is something I want in Montenegro, but there is one thing that I want from Qingyang Daoren, I didn't expect him to really have it, if he doesn't, I will have to work harder, oh, by the way, I promised him to exchange roast venison for the alum oil in his hand, you can reluctantly let someone roast some venison for him."

Ning Qi said before remembering that he had promised the old Taoist priest to give him venison today, but Yan Yunzhou did not show resistance to the Qingyang Taoist at this moment:

"Since you agreed, it would be good to let people go hunting in a while."

Ning Ji nodded, it would not be wrong to give him a deer, alum oil is actually crude sulfuric acid, he only needs to further purify it.

But if the old Taoist priest didn't have alum oil, he would probably have to distill the gallium to prepare alum oil first, which would be time-consuming and laborious, and he would have to find raw materials.

"You go to bed early, I'll draw the installation."

At this moment, when the raw materials are all ready, the installation diagram is easy to draw, and Ning Qi returns to the table.

First of all, he wrote on the paper the first raw material that needs to be synthesized, chlorosulfonic acid, which can be prepared by fuming concentrated sulfuric acid and concentrated hydrochloric acid, so first he needs to get concentrated sulfuric acid first.
