Great Song

When she became interested, Zhen Qiong also became serious, and obediently followed Han Miao to learn the rules of face saints.Under the guidance of the other party, he adjusted the demonstration process of gall water smelting copper to make it look more orderly and free-spirited.

There were many changes, and Zhen Qiong gradually became enlightened.Isn't this the advanced version of the application for project approval?To show the means in front of people, it is best to be inscrutable, novel and unique, so as to attract the attention of the viewers and get attention.No wonder Master often taught them to learn how to apply for project approval.It turns out that this ability is useful even in front of the emperor!

After figuring this out, Zhen Qiong became more confident.It's just that people are not as good as heaven, and before he could consolidate his practice, Han Qi sent someone to take him into the palace the next day.

how so fastZhen Qiong was dumbfounded.Seeing this, Han Miao comforted him, "It must be the emperor who pays attention to it, so he hastily called you into the palace. The method of refining copper with gall water is not difficult, just practice it in front of the emperor."

Knowing what Qiong'er was thinking, Han Miao sent someone to send a letter to Han Qi, and described in detail the process of smelting copper with gall water.The other party sent someone to pick him up the next day. Such a haste clearly implied a deep meaning.How can you back down at this time?Anyway, Qiong'er's set of experiments has been done proficiently, and it is enough to reproduce it safely.

After exhorting carefully, Han Miao personally sent Zhen Qiong to the gate of the palace.After getting out of the car, carrying the wooden box full of bottles and cans, Zhen Qiong took a deep breath, straightened her clothes, and strode into the palace.

"The telescope presented by Shen Qing is really an important weapon for the military. I read what Chen said, can this mirror look at the sky?" With the telescope, Zhao Xu even shortened his morning court time.After the dynasty was over, Shen Kuo was immediately summoned to ask questions.

"Go back to the official's house. This mirror is too small. You have to grind a bigger lens to see the sky. It's just that the sun, moon and stars are unfathomable, and you can see thousands of miles away, but you may not see them clearly." With the chancellors of the two governments, Shen Kuo was inevitably still a little nervous.The speed of speaking is also faster, for fear of not being able to answer clearly.

If it were someone else, I'm afraid they would have already started bragging about how far the binoculars could see, but Shen Kuo had an answer and didn't dare to speak nonsense.For such a courtier, Zhao Xu still admired it quite a lot. He nodded with a smile and said: "Shen Qing's "Southern Suburb Style" is well written, and it won my heart. It is also a great achievement to present the telescope. The promotion to Prince Zhongyun, Promote the Sitian Supervisor to supervise the construction of the mirror for viewing the sky."

Now there is no crown prince in the East Palace, but from the editing and proofreading of Zhaowen Pavilion to the crown prince Zhongyun, it has skipped several levels.Shen Kuo's eyes turned red immediately, and he bowed to thank him.

After rewarding the meritorious officials, Zhao Xu said to the left and right: "This binoculars is enough to defeat the enemy on the battlefield. You might as well make two hundred first and send them to the Western Army."

Aspiring to regain Yanyun, Zhao Xu naturally understood the significance of the telescope for marching investigations.Now that Xixia is fighting more and more, if the guarding generals are equipped with binoculars, the chances of being ambushed will be greatly reduced.

Hearing this, Tang Jie, the envoy of the third department, immediately stepped forward and said, "The telescope is expensive to build. Now that it has just been added to the border, and a city shipping department has been set up in Quanzhou, the treasury is empty. I really can't afford so much money."

The third envoy, who is in charge of fiscal revenue, expenditure and taxes, is the chief steward of the imperial court. He said that the treasury is empty, so there must be difficulties.Zhao Xu couldn't help frowning: "Isn't it possible to make two thousand handles, and only two hundred are not enough?"

Tang Jie shook his head immediately: "The glass of that quality can't be fired even by a supervisor. If you buy it, the cost of the lens alone will not be less than 2000 million yuan."

A pair of armor is only about [-] yuan.These lenses are more than three times more expensive!

Unexpectedly, as soon as he finished speaking, the privy envoy Wen Yanbo said: "A binoculars, you can win a team of sentries, how can several armors compare with it? It's just that this thing is related to military affairs, and it is always inappropriate to buy it. "

He only said it was inappropriate, but did not say in detail, it was precisely because the glass used to make the mirror came from Han's shop.The owner of this shop has a lot to do with Han Qi.

Han Qi had been prime minister for nine years, and everyone in the court thought he should retire.Unexpectedly, this person would repeatedly advise and add new Bianqian and Shibosi to tax the treasury.Needless to say, this idea seems to have some effect after trying it out.But she can't escape the reputation of making money by flattering her.If you don't insinuate at this moment, when will you wait?

"The glass on the market is not in violation of the regulations, so how can we take advantage of the people?" Before anyone else could speak, Tang Jie stood up and objected.Just kidding, Mr. Han has already conceded that he can increase the business tax on extravagant things.There is no way to know how much tax can be increased just by glass. How could he let Wen Yanbo do something like kill the chicken and get the eggs.

"Then please plan to allocate money to send this military weapon to the Western Army." Wen Yanbo immediately retorted.

Seeing that the two were about to quarrel, Zhao Xu turned his face away with a headache: "What does Mr. Han think?"

Han Qi stood at the head of all the ministers, and reminded him calmly: "Did the officials forget the Qianshan mine?"

Um?Zhao Xu blinked, and really remembered this, and hurriedly asked Shen Kuo who was standing below: "Shen Qing said that there must be a big mine for the gallbladder water produced in Qianshan Mountain, is there such a thing?"

When Shen Kuo saw the quarrel between several princes, sweat came down his forehead. When he heard the question from the emperor, he hurriedly replied: "It is true! It is because there is copper in the ground that the gallbladder is born, and the copper can be extracted. I have seen the transformation with my own eyes. Dare to say so.”

This remark surprised several other ministers, Han Qi hadn't mentioned this before, hadn't he?He even planted a foreshadowing!If he really expected it, wouldn't he be able to secure the position of Prime Minister again? !

Seeing everyone's expressions, Han Qi knew what they were thinking, and smiled slightly: "Shen Zhongyun learned about this method from a Taoist master. I have invited this person, and he is outside the hall. The officials might as well ask them."

This arrangement leaves no room for retreat.The situation was unclear, and several important officials kept their mouths shut, but Zhao Xu beamed with joy: "Recruit him quickly!"

Searching for mineral veins has never been a trivial matter.Based on Shen Kuo's words alone, it is absolutely impossible to spend a lot of manpower and material resources to find copper mines.But if you can see the evidence with your own eyes, things will be different.If Han Qi dared to do this, he must have some confidence, how could Zhao Xu refuse?

The servant summoned him, and after a short while, he saw a man in cassock walking slowly into the inner hall.

The man was about seventeen or eighteen years old, not too tall, and very handsome.Dressed in a blue Taoist robe, embroidered with silver clouds and black cranes, it looks heavy, but it seems to be floating when walking, with big sleeves waving.She only wears a jade crown on her head, her black hair is lightly tied, her neck looks slender and her eyes are clear.As far as appearance is concerned, I'm afraid it's not as good as the high skills in the temple.Just such a trail, can it explain the reason for the smelting of copper with white gall water?

Zhen Qiong didn't care about the eyes of the crowd, so she walked to the front of the imperial court so generously, bowed and saluted: "Xiaodao Zhen Qiong, I have seen the official family."

Who can have a place in the Chui Gong Palace, who is not a veteran who has been in the officialdom for decades?Everyone immediately realized that this trail was not afraid of them.Even for the emperor on the seat, there is only respect and no fear.Only in this way can you show such a calm look when you meet for the first time.

Zhao Xu looked at the trail with great interest, and then said: "Listen to Shen Qing, do you know the reason why gallbladder smelts copper?"

"Exactly." Zhen Qiong replied neatly, "If the officials want to see it, Xiaodao has also brought equipment, so they can demonstrate it in class."

"Sure." Zhao Xu regained his energy. He still cared more about whether there was a big mine in Qianshan than his appearance.

What Brother Miao said was really good.Seeing that the Son of Heaven was eager to ask for the courage to smelt copper as soon as he came up, Zhen Qiong felt more at ease in his heart.He walked all the way from the palace gate to the Chuigong Hall just now, and he was indeed a little nervous.But when he entered the house, he found that the hall was not as big as he had imagined, and the emperor was very young, and he was not as calm as Brother Miao.He immediately relaxed again.

But it's just a process of applying for project approval. He has no shortage of funds now, so what is there to be afraid of!

With this in mind, Zhen Qiong felt relaxed and her movements became more and more free.The servants brought the table, and he took glass vessels from the wooden box, put them all on the table, and took out a glass bottle, and showed it in front of everyone: "This bottle contains gall alum, also known as alum. Zeng Qing. By melting water with this substance, you can get gall water."

Everyone in Zeng Qing knew about it. Those who were well-informed and well-informed had already remembered the saying in "Huainan Wanbi Shu" that "if Zeng Qing gets iron, it will turn into copper", and they couldn't help squinting their eyes slightly.

However, some were curious and asked one more question: "Why use glassware?"

Using such precious things to display gallbladder smelting copper, is it also particular?

Zhen Qiong looked at the old man suspiciously: "Of course it's because the glass can see clearly."

Everyone: "..."

Regardless of the expressions of the others, Zhen Qiong raised her long sleeves, poured the blue crumbs into the glass, and poured some water.After a while, the water turned blue.Then, he took a thin iron bar and put it into the solution: "When iron meets gall water, it can replace copper. This is the method of refining copper with gall water."

All eyes were fixed on the iron bar.Even if you have heard the rumors and read the books, it is not true what you have seen with your own eyes.Sure enough, not long after, a layer of red appeared on the silver shiny iron sheet.Zhao Xu immediately ordered his servant to fetch the iron bar, washed it clean, and held it in his hand for a closer look.I saw that the top was really evenly plated with a layer of copper.Even though he had heard of gall water smelting copper, he had never seen it with his own eyes, so he couldn't help but praise: "It's really amazing!"

Wen Yanbo sneered coldly: "Smelting copper with gall water has been recorded in the Han Dynasty. This method is nothing more than Huangbaishu. How can it confirm the theory of copper mines?"

Zeng Qing is not copper, even if copper can be smelted from gall water, it doesn't mean that copper ore can be found.The phrase "Huangbaishu" is even more embarrassing.If it is true, it is inevitable that he will be accused of seducing the monarch.

Zhen Qiong didn't understand at all, but nodded in agreement: "This experiment is just gallbladder refining copper, but it still needs to be verified. I also brought the corresponding medicine. If you dare to ask the officials, you have to see See?"

Zhao Xu immediately said: "Let the Taoist priest give it a try."

He unconsciously used the word "please", which attracted the attention of several gentlemen.Zhen Qiong didn't understand this, and took out a few things from the wooden box.

A glass bottle with a wick in it, a set of glasses with long tubes, and an iron shelf of odd shape.

"Sulfuric acid must be used to produce bile. This substance is strong and can corrode gold and iron." Zhen Qiong said, carefully pouring out a few drops of liquid from a bottle with a lid, and dripping it on the table.The brocade spread on it was suddenly blackened, with holes in it.

Everyone's teeth were sore for a while, even Zhao Xu himself couldn't help but look at Han Qi.How could such a dangerous thing be brought to the imperial court?

Zhen Qiong didn't care about the faces of others, and said seriously: "Copper is not suitable for decay. If you want to melt copper, you must use this kind of strong acid and heat it."

After all, he took a few copper wires, put them into a glass, poured some concentrated sulfuric acid, and screwed on the lid.The glass is firmly placed on the stand, and the thin tube at the other end is inserted into the water glass on the side.

He is wearing a Taoist robe, although the sleeves of the robe are wide, but he does these things smoothly, making it dizzying for the eyes.

After placing the utensils properly, Zhen Qiong also specially explained: "The exhaust gas produced by refining gall water is also highly poisonous. But it will be fine if it is poured into water, so the officials don't have to worry about it."

After speaking, he took out a mask for himself, lit the alcohol lamp, and put it under the glass.

It's okay, why don't you bring a cloth towel!Several important officials in the palace cursed in their hearts.However, the path was standing next to the poison, and the emperor didn't give an order to stop it, so no one dared to stop it rashly, so they all leaned back together, covering their noses with their sleeves.There were also many people who gave Wen Yanbo a look, blaming him for asking something wrong, they insisted on asking this!

Zhao Xu himself was also shocked, but after looking at the calm path and Han Qi who was calm and calm, he managed to regain his composure and looked at the table.I saw the glass lamp filled with clear liquid, the flame flickered, and the liquid in the cup was boiled in a short time.During the ups and downs of the solution, the copper wire in the cup became thinner and thinner, and gradually melted, turning the white water blue.

Seeing that the copper wire had reacted cleanly, Zhen Qiong extinguished the flames with an alcohol lamp cover. After making sure that no exhaust gas was discharged, she took off her mask and said, "Please look at it, this is the source of gall water. It is the nature of heaven and earth that makes copper become Copper alum, so columbine always grows with ore, where there is so much bile, there must be a lot of copper!"

Seeing is believing, this is the simplest truth.All the cups and cups are clear and transparent, every move is in front of others, and the Xiaodao explained it so clearly, how can there be even a little bit of mystery?Even Wen Yanbo, who had questioned him just now, didn't dare to say more now.

Zhao Xu stared at the glass for a while, and suddenly showed joy: "There is a big mine in Lead Mountain!"

"That's right." Zhen Qiong nodded firmly, "Follow the courage to search carefully, and you will definitely get something."

This is amazing news!When the Shaozhou Copper Mine was discovered that year, it more than doubled copper production and filled the treasury.Now that there are so many guts in Lead Mountain, can there be no big mines? !

Tang Jie on the side also laughed: "There is a mine in the lead mountain, and it can also mint coins. The nearby river is unobstructed, which can save a lot of effort!"

With copper mines, there will be money. Are you afraid that the national treasury will be empty?

Wu Kui, the political adviser, frowned: "Such a large mine has been discovered for hundreds of years since the Tang Dynasty. I'm afraid it's located in a deep mountain, so it's not easy to dig."

Wen Yanbo also echoed: "Opening mountains for mining is too harmful to the people. Since gall water can also be used to smelt copper, why not set up more factories to increase the production of gall copper."

This is an old-fashioned opinion, it saves time and effort, and it will not be a waste of money.However, Zhao Xu still frowned, how much copper can be smelted out of courage?I don't know when it will be exhausted. Compared with mines, it is far inferior.

Of course Tang Jie knew what the emperor was thinking, and immediately said: "It is better to send people to search for mines first, and then ask the Raozhou government to mine more copper. It is safer to do both..."

Several prime ministers started arguing like this.Unexpectedly, a voice suddenly appeared from the side: "Since it is mining, why not use explosives?"
