Hand over the jade seal first [Infrastructure]

Xiao Zirong was indeed very surprised. He thought it would be good to find it within half a year, but it turned out so quickly?

Ling Fu said hastily: "We did find it, but not many, and we didn't find the ore deposit His Highness mentioned."

After hearing this, Xiao Zirong was a little surprised: "Where did you find scheelite when you didn't find the deposit?"

Ling Fu said: "Someone has collected this thing."

After his explanation, Xiao Zirong realized that the property of scheelite to emit light when exposed to ultraviolet rays was not discovered by no one, but everyone didn't know what the use of this thing was, so they thought it was rare and used it as a gemstone collection.

Because the stock is scarce, and there is no place where it can be mined in large quantities, the price is not low.

Xiao Zirong: ...

Really unexpected.

"How many can you find now?" he asked.

Before Ling Fu could speak, Xiao Xuexing said, "No matter how much, take it."

"Don't." Xiao Zirong said hastily: "What are you doing with this unjustified money? When you find the deposit later, the price of this thing will definitely drop."

Xiao Xuexing turned to look at Xiao Zirong: "Do you know where the ore deposit is?"

Of course I know, although I’m not particularly sure, after all, scheelite was only discovered in the seventeenth century, which is a long time ago from modern times, and the changes in topography and landforms are not ordinary.

It's just that things like mineral deposits are usually formed after a long time, so they shouldn't move their positions. He just needs to check where the later generations of scheelite are located and where they are now.

But this can't be said. Wouldn't it be a prophet to tell the truth?

So he swallowed the words and said: "I'm not sure, but this thing is a kind of mineral. If you are lucky, you can find it in caves. The ones that are handed down now may be washed out of caves."

How could Xiao Xuexing not see his hesitant look just now, but he didn't ask any more questions, just nodded as if he didn't see it: "Then how much do you want?"

Xiao Zirong was silent, how would he describe it?Speaking of one piece, the big one is one piece, and the small one is also one piece.

Seeing his embarrassment, Xiao Xuexing couldn't help laughing: "It's not short of your food and clothing expenses, what's the point of spending some money." He turned to Ling Fu and said, "Buy the ones you find first."

It's okay if it's not a big acquisition, even if it's bought, it's probably not much.

Xiao Zirong muttered, "If you have money, you can't waste it."

Xiao Xuexing patted his head and said, "Rest after eating."

The corner of Xiao Zirong's mouth twitched: "Brother, you can't let me eat when I'm full, sleep and wake up, I'll gain a lot of weight if this continues."

Xiao Zirong pinched his face with his hand and said, "It's good to grow some flesh, let's see how thin you are now."

Xiao Zirong patted his hand away and said confidently: "I am of standard body type!"

Seeing that his mood didn't seem to be affected much, Xiao Xuexing said with peace of mind: "Even if I let you out, what can you do?"

Xiao Zirong lowered his head and looked at his feet, it seemed that he was the same.

This injury is not serious, but the problem is that the injury is all on the bottom of the foot, so walking is out of the question.

Xiao Zirong was very sad: "Then I have to go out."

Xiao Xuexing said: "We'll talk about tomorrow's matter tomorrow, you won't go out at this late hour, will you?"

Xiao Zirong looked up at him: "Then I have to go back to my room."

After Xiao Xuexing asked people to put away the things on the bed, he bent down and picked him up, put him on a chair beside him and directed the people to rearrange the bed, and then said: "You have been sleeping with me these two days."

Xiao Zirong blinked: "Why?"

Xiao Xuexing said: "I sent someone to do a ritual in your room, it will take a few days."

In fact, he invited wizards, monks, and Taoist priests all over, no matter which one would always work.

As for whether there are ghosts of his relatives there, he doesn't care anymore.

If his close relatives love him naturally, even if he becomes a ghost, he should know that he values ​​Xiao Zirong and will not harm or threaten that child.

If doing so means that the other party may not remember anything or has become a ghost, then why should he care?It's better to transcend the other party as soon as possible and let him enter reincarnation.

Xiao Zirong couldn't laugh or cry after hearing this: "No, it was a misunderstanding before, what are you doing with this?"

Xiao Xuexing wanted to seek peace of mind, but he was afraid that Xiao Zirong would feel guilty, so he said: "Then let the misunderstanding continue, do you want others to know that you were frightened by the maid sent by His Majesty?"

Xiao Zirong immediately silenced, if the truth got out, would he lose face?

So... is it true that there is a female ghost causing trouble even if she is hammered to death?

Xiao Zirong frowned and said, "Will Xiao Yan and the others have anything to say?"

After all, he drove away those people from the Nuo opera back then, and insisted that there were no female ghosts in Taoyuan City, but he turned his head around and "bumped into ghosts" and slapped him in the face... It seemed very embarrassing.

Xiao Xuexing knew what he was thinking at a glance, reached out to hug him back, patted his forehead and said: "Don't think so much, go to sleep."

Xiao Zirong:? ? ? ?

He just woke up not long ago, how did he sleep?

At first he thought he couldn't fall asleep, but when Xiao Xuexing finished washing and lay beside him, he sniffed the fragrance on her body and said, "Brother changed the fragrance? This smells good."

Xiao Xuexing responded: "You like to turn around and have someone send you some."

This fragrance is a bit special, not very strong, it smells like nothing, if you smell it carefully, you will feel that you can't smell any fragrance, but when you don't care, there will be a wisp of fragrance that penetrates into the nasal cavity, which makes people very happy memorable.

It can be said that it matches Xiao Xuexing very well.

Xiao Zirong responded, feeling sleepy for some reason after smelling the fragrance, closed his eyes and fell asleep again.

The next day, when he woke up, Xiao Xuexing was still not there. After washing up, he tried to take two steps on the ground, and then sat back with grinning teeth.

When Ah Yin came to help him apply the medicine, Xiao Zirong suddenly remembered that the first time he left Taoyuan City to go to the county seat, he walked a lot, and when he came back, his feet were full of blisters, which were worse than now after they were broken. It hurts a little.

But at that time, he directly dug a little coriander root and applied it on before continuing to walk, but now he couldn't stand the pain at all, and felt that he was a little coquettish by Xiao Xuexing.

As for why it has something to do with Xiao Xuexing... Before Xiao Xuexing came over, he often did physical work, walking on mountain roads and so on. Do-it-yourselfer, the rest of the time lives a corrupt aristocratic life.

He touched his stomach, um, it's okay, although there are no particularly obvious abdominal muscles, but there is not much fat either.

When Xiao Zirong was reflecting on himself, Ling Fu asked someone to come over with two stones.

Those two stones are scheelite.

Although it sounded logical before, it was the first time for Xiao Zirong to see scheelite.

Under the sunlight, the scheelite does emit a faint purple light, but it is not obvious, the kind that will be ignored if you don't pay attention.

However, this may also be because the two pieces of scheelite are rough stones.

There are quite a few associated ores of scheelite. Even if he doesn't know the original appearance of those minerals, Xiao Zirong can see that there are at least two kinds of ores associated with the two pieces of scheelite in front of him.

It's just that these two ores are very rare, and even if they are stripped off, they may not have much effect.

Now that the ore was found, Xiao Zirong immediately became energetic and planned to start working.

The first thing is to extract the scheelite. The tungsten wire must be pure scheelite without any impurities.

Xiao Zirong had listed all the methods of extracting scheelite before, but the first thing he had to do was to burn a few more glass bottles to collect carbon dioxide.

Because the extraction of scheelite requires the use of soda ash, there is no need to make this thing now. Anyway, this thing can be regarded as an important basic material for chemical industry, so it will not be caught when it is used in advance.

As for the production of soda ash, Xiao Zirong chose the Soxhlet method after choosing for a long time.

Hou's soda-making method is indeed more suitable for today's Qi State. After all, it can not only improve the utilization rate of table salt, but also produce ammonium chloride, a chemical fertilizer. However, this method has something that they can't get at all at present-ammonia gas.

The production of ammonia is a bit more complicated, and nitric acid is also used in it.

Sulfuric acid and hydrochloric acid can be produced if you think about it, and nitric acid... Unless it can be obtained in nature, Xiao Zirong will not be able to produce it for a while.

So he can only give up Hou's soda making method, even if he is very greedy for ammonium chloride, it is useless!

The Soxhlet process uses table salt, ammonia and carbon dioxide.

Among them, salt is definitely not lacking in Taoyuan City. As for ammonia... it can also be replaced, that is, urine.

So what remains is the production and collection of carbon dioxide.

The production of carbon dioxide is actually not difficult, it is produced by the metathesis reaction of limestone and dilute hydrochloric acid.

After writing this, Xiao Zirong discovered that the most important thing to do now is sulfuric acid.

Hydrochloric acid is obtained by heating sulfuric acid and adding salt.

After deciding to make sulfuric acid first, he couldn't help laughing, because among the steps he originally wrote down to make sulfonamide, the first chemical material to be made was also sulfuric acid.

Sure enough, three acids and two bases are the basis of all chemical industries.

It is estimated that after he finished refining the scheelite, the three acids and two alkalis would at least give him two acids and one alkali, and the remaining nitric acid and caustic soda... It doesn't seem too difficult.

Xiao Zirong thought of this and closed the document, waved his hand and said, "Let's go, let's go to the Ministry of Industry!"

It is definitely not enough for him to do this alone, but if you want to get help, at least let Zhai Xi and the others understand some of the truths.

After all, he didn't make these things and then he didn't use them after one use. Since he made all the things, he had to develop slowly in the future.

After hearing Xiao Zirong's words, before Ah Yin had time to say anything, she saw her city lord standing up very excitedly, and then... sat down again with a face of pain.

Xiao Zirong forgot about the injury on his foot again.

He looked at his feet with a little melancholy, did he want to call everyone over?But there are more equipment at the Ministry of Industry.

After seeing his expression, Aman immediately said: "City Master, wait a moment."

Before Xiao Zirong could react, Aman ran away like a gust of wind, and she came back after a while, and at the same time pushed a wheelchair over.

Aman said happily: "The city lord can sit on this and don't have to worry about hurting his feet."

Xiao Zirong: ...

Good guy, did he prepare the wheelchair for himself after working for half a day?
