Great Song

"Teacher, the green alum has already melted into water, can we start experimenting?" Qingfeng asked cautiously.

"Let's get started!" Zhen Qiong let out a heavy breath, "You can't make it with vitality, but you should be able to do it with green energy!"

The teacher's persistence is what Qingfeng admires the most.I thought of using alkali silver to replace the bauxite before, but I actually got the solution and replaced it with a wet method, but I didn't see the shadow of the metal at all.Once the alkali silver is put into the water formed by bauxite, a series of bubbles will be produced immediately, and the temperature will rise, and white flocs will overflow.This is not like a replacement, but rather like a reaction between alkali silver and water.

After more than a dozen tests, all links have been checked, and alkali silver was used alone to enter the water, only then did I find that this substance can really react with water.It's just that the bubbles are insignificant when it meets cold water, and become more after heating.

Now everyone is a little bit waxy.The mentor was unwilling to give up, and after thinking hard for a while, he proposed another plan.First replace the vital qi in the bauxite with green qi, change its properties, and then try again.This green gas is obtained from hydrochloric acid, the color is yellow-green and highly poisonous, and it is also more unstable and volatile.If green gas can be used to replace vitality, the products produced will inevitably be less heat-resistant and easy to replace.

So a group of people tried again, and finally mixed and heated charcoal, green gas and bauxite to produce green alum like white powder.Then dissolve it in water to become a replacement solution.

Isn't it time to experiment?

Qingfeng put on protective glasses and a mask, carefully took a piece of polished alkali silver, and put it into the solution of greening alum.In the expectant eyes of everyone, dense bubbles appeared around the small piece of alkali silver, scrambling to overflow, just like when using bauxite before.

Is this going to work?Even Qingfeng couldn't help but slumped his shoulders.The green alum that has been produced so hard is still useless!

Zhen Qiong looked at the bubbling beaker, feeling a little frustrated.He originally thought that it could be done with green energy, but it took half a day, but it was still useless.Is it possible that alkali silver cannot react with the solution?So how to deal with it?

Just as everyone in the room was downcast, Duan Xuanshuang rushed in quickly: "Master! My master has discovered a new kind of gold that can cure diseases!"

"What?" Zhen Qiong stood up abruptly, and rushed out of the room without saying a word.He has been researching for so long but still hasn't figured out why, why did the senior brother discover the new gold?

Zhen Qiong went quickly enough, but Chi Liaozi was more impatient than he thought, when he saw someone coming in, he grabbed him: "Junior brother, I seem to have found the root of the cure for galls!"

ah?How could it be gall?Isn't this a big neck disease?

Zhen Qiong was dragged to the table and saw the black and purple crystals in the bottle at a glance.Chi Liaozi had already picked up the bottle excitedly: "Isn't there a saying in "Behind the Elbow" that if you suffer from galls, you should eat more seaweed and kelp? I found some seaweed and burned it to ashes, and used it to refine it. Let's see if we can find out the reason. As a result, when it was soaked in sulfuric acid two days ago, purple smoke suddenly appeared from the object, and after condensing, it became the crystal powder in front of us..."

Zhen Qiong widened her eyes, looked at the half-bottom of the bottle, and murmured: "This is a crystal, I'm afraid it's not metal, but a kind of stone..."

"Whether it's gold or stone, this thing must be the key to cure galls!" Chi Liaozi paused, and was a little frustrated, "I just tried it with rats and rabbits, and this thing is also very poisonous, and it's easy to swallow. It can suffocate small animals, and it can also cause blood in the feces, and even violent death. I am afraid it is also somewhat corrosive, and I don’t know how to use it as medicine? Oh, yes, this substance is not very soluble in water, but it can be dissolved in alcohol. , will turn blue...

Before Chi Liaozi finished nagging, Zhen Qiong's eyes suddenly lit up: "Can this thing dissolve in alcohol?"

"Isn't it? After melting, it turns yellowish brown, and the smell is a bit pungent." Chi Liaozi said immediately.

"Have you tried to observe with a microscope? Alcohol can sterilize bacteria, but after being dissolved in this substance, will the effect change?" Zhen Qiong asked again.

"I haven't tried this before!" Chi Liaozi suddenly regained his spirits, "Do you think there is a difference, Junior Brother?"

"There will definitely be!" Zhen Qiong immediately said, "Such a poisonous thing, killing Gu must be useful, as long as it doesn't cause disease!"

He has already remembered, don't those herbal Taoist temples have a kind of "purple potion"?It is the purple medicine that is dissolved in alcohol, and the effect is quite good. It is said that it can also cure beriberi.It's just that they don't have much contact with Taoism about these things, and they don't quite understand the principles.

However, this proposal has opened Chi Liaozi's mind, and he nodded again and again: "The brother's words make sense, I will try it now to see if I can make a better Gu-killing medicine. It's just that the toxicity needs to be controlled. There is also a question of how to refine the elixir to treat galls..."

Chi Liaozi was already fascinated by these thoughts, and he didn't even care that Zhen Qiong was still there, so he immediately summoned Duan Xuanshuang to help him prepare the utensils.

Looking at the old Taoist who was completely selfless, Zhen Qiong couldn't tell whether it was jealousy or envy.Although the purple medicine was not too new to him, Chi Liaozi discovered it by himself.If this is really refined into medicine, wouldn't it also be famous in history?

But the brothers have made results, but he is still empty-handed.Zhen Qiong clenched her fists, turned her head and left.He is not reconciled!Now that the green alum has been produced, it may be only one step away from success, how can it just retreat?Since no new gold can be produced by the wet method, he switched to the dry method and started the furnace to smelt it!

Unexpectedly, the mentor would go and return so soon, Qingfeng carefully asked: "Men, did the uncle really discover the new gold?"

"It's not new gold, but a new kind of stone. But it's a great achievement, we can't be left behind!" Zhen Qiong waved her fist and said loudly.

Seeing the teacher's appearance, Qingfeng quietly let out a sigh of relief.Discovering new gold is the most important thing for his mentor. Now that his uncle has taken the lead, he thought that his mentor would be depressed, but unexpectedly he cheered up again.That's right, the recorded experiments have been done more than 3000 times, are you afraid of failing once or twice?

"Once this green alum is heated, it is easy to melt, and the melting point of alkali silver is not very high. If you put the two in a closed alchemy furnace, maybe there will be a replacement and new gold will be purified!" Zhen Qiong said her plan come out.

"But alkali silver is easy to blend with vitality, and the bauxite also absorbs vitality, will it produce two yuan compounds instead?" Mingyue standing beside him hurriedly asked.

"That's why it needs to be airtight. The alchemy furnace for making alkali silver must remove the atmosphere, and the same must be done for purifying new gold." Zhen Qiong replied decisively.

Qingfeng was shocked when he heard the words: "There is still a vacuum? What if it blows up?"

Alkali silver ignites when it sees a fire. It is not safe to heat it with green alum. Now it needs to pump air and increase the pressure. It is really hard to say whether it will fry the furnace.

Unexpectedly, Zhen Qiong shook her head decisively when she heard the words: "Even if you practice less every time, you still have to try. The way is like this, if you don't try, you will be dead everywhere. Only try, and then you can find another way!"

So far, it seems that there is no better way to think of it.Qingfeng gritted his teeth, and finally nodded vigorously: "It's all up to the teacher!"

These days, Zhen Qiong is busy again.It is said that it was because Chi Liaozi made a new elixir that he was also attracted to it.Han Miao had nothing to do with this competitive spirit, he could only order people to watch him carefully, and he would go to see him from time to time, so as not to make him sick again.

But at this time, Han Miao will inevitably have a little pantothenic acid.Qiong'er cared about Dao far more than others.No matter how hard he tried, he couldn't get more attention.To say loneliness, there must be some.But what he likes is a man, and he has the great wish of establishing a sect and leaving a name in history, so he will never regard him as the sky and revolve around him.However, while feeling sour, Han Miao also understood that besides Dao Dao, maybe Qionger cared most about him.What is a little loneliness compared to those shocking achievements?

On this day, Han Miao called a few shopkeepers as usual to arrange everything for the business.In the middle of the conversation, there was a sudden noise outside the door, and immediately, the door was pushed open with a "bang", and a figure rushed in, no matter how many people were around, just at one end Tucked into Han Miao's arms.

"Brother Miao! Brother Miao! I found it!"

The voice was astonishingly loud, as hard as hugging his neck. Han Miao lost his breath and hugged the person in his arms.There were all kinds of smells on the man's body, pungent, burnt, sour, and even a lot of sweat, but he didn't even clean up, he ran straight to his side, and plunged in.

His heart seemed to be rubbed hard, Han Miao patted his back with his hands, and asked softly: "But new gold has been refined?"

In the room, those shopkeepers who were winking have already retreated, and no outsiders disturbed them anymore.However, Zhen Qiong didn't care about this, and broke out of the embrace, and stuffed a small glass bottle over.

"This is new gold! Refined from alum! It is especially easy to absorb vitality, slightly inert than alkali silver, but it can be easily replaced by other metals, soluble in acid and lye. I haven’t been able to find out. But it is extracted from alum, as long as you find the right method, you may be able to mine a large amount, which is not inferior to copper and iron!” Zhen Qiong was trembling all over, and the speed of her speech was astonishingly fast, but His hand holding the bottle was very steady, as if he was about to hand over the most precious treasure in the world to Han Miao.

In that bottle, there was a piece of metal, silvery in color, not as big as a mung bean.Just lying alone at the bottom of the bottle, there is no novelty at all.

Han Miao raised his head and met his still excited eyes.

"Brother Miao, I made this, you can name it!" Zhen Qiong ran out from the alchemy room without changing her clothes, let alone eating and sleeping.These things are not as important as announcing the good news to Brother Miao.This is new gold, real new gold, and it took him five years to refine it.He must let brother Miao share this feat that is enough to leave a name in history!

The man's face was also dirty, red and black and white, just like a cat.But his expression is so solemn, even better than the appearance when he handed out the marriage certificate that day.

Han Miao smiled, and gripped the small glass bottle tightly.The other hand picked up the pen, without hesitation, and wrote an ink word on the account book in front of him.

That is the word "couple".

Holding the pen, Han Miao looked at Zhen Qiong: "Since it's your new gold, how about using it as a name?"

That is a lover, a Taoist couple, a companion, and a life and death companion, sharing weal and woe.

Zhen Qiong's eyes lit up immediately, and she laughed happily: "This name is good! By the way, I need to add two strokes!"

As he said that, he grabbed the pen and drew two crooked lines on the upright and handsome characters: "Since it's gold, you have to use the '钅' part!"

That word just became "aluminum".A new word that has never been seen before, but will be known to the world in future generations.

Han Miao smiled and took the pen in Zhen Qiong's hand, threw it on the table, stretched out his arms, and hugged her in his arms.A kiss mixed with the fragrance of flowers was imprinted on the lips stained with charcoal gray.

Affected by the strength, the bean-sized metal rolled over in the small bottle held in the palm, hit the wall of the cup, and fell back to the original place lightly and delicately.

(End of text)

The author has something to say: Tomorrow is the college entrance examination. First of all, I wish all the babies who take the exam can perform at a super level and achieve ideal results!

What Chi Liaozi refines is not purple potion, but iodine element. When mixed with alcohol, it becomes iodine tincture. It does have certain curative effect on skin diseases, but it needs to be deiodized, so it should be used with caution according to the doctor's advice.

Impure magnesium metal was first produced by Anton Rupprech in 1792 by heating a mixture of bitter soil and charcoal. Zhen Qiong used the half-baked Pidgeon method, and the purity would be a little higher.Sodium and potassium have to wait for the electrolysis experiment to appear before they can be extracted.

The electrolysis of aluminum is more complicated than that of sodium and potassium, mainly because the temperature cannot meet the requirements for a long time. Before cryolite was discovered, metal sodium or potassium amalgam was heated together with aluminum chloride, so The price is so expensive.That being the case, magnesium, which is more active than aluminum, can theoretically replace aluminum.

As for why it cannot be replaced with an aluminum salt solution, it is because the activity of potassium, sodium and magnesium is too high, and it will first react with hydrogen ions to generate hydrogen gas.Of course, they are all inferences based on random checking of information. For the novel, let’s make Bo Jun laugh.

At this point in writing, it can be considered a conclusion.The hidden dangers that would lead to the sudden demise of the Northern Song Dynasty have been eliminated little by little. Some are subtle, some are erroneous, and some may cause variables, but the general direction will definitely not be so outrageously wrong.

Afterwards, there are still some idle pens, which will start from more perspectives.After all, it is a change in the fate of the country, and it would be too stereotyped to follow the original writing method.However, it is customary to ask for two days off first, take a breather and then come to the episode.I still want to thank the little angels who followed me all the way. If you have any special episodes you want to watch, you can also bring them up and see if you can write about them.
