Lishui County.
The alchemy furnace was transported to the yard, and Su Jing's alchemy life naturally began.
According to ancient methods, Su Jing used green alum to make elixirs.
In order to avoid the impact of toxic gases on health, Su Jing specially made some glassware specifically for holding raw materials.
Green vitriol is actually natural ferrous sulfate.
Su Jing placed the green vitriol in the alchemy furnace, added an appropriate amount of rice vinegar, covered the alchemy furnace, and fired it directly below.
The fire was burning brightly and the small courtyard was very warm.
But Su Jing did not stay in the yard to study like Zhu Biao and Zhu Ru.
After all, we are doing chemistry, so we still have to pay attention to our health.
Ancient alchemists would always make alchemy in some closed room, which was really self-inflicted.
Poor ventilation conditions can easily cause the accumulation of harmful gases.
In fact, most of the lifespans of ancient alchemists were not very long.
Although there are many classics that record the immortality of alchemists, such as the legendary alchemist and medical fairy Ge Hong.
Although it is recorded that he lived to be eighty-one years old, Su Jing has always been skeptical about this.
After all, this ancient alchemy technique simply means refining heavy metal concentrates.
For example, Huang Dan, this kind of elixir is also called Lead Dan, Dong Dan, and Guang Dan.
Its main ingredients are refined from lead, sulfur, and saltpeter.
Just look at this ingredient. It would be strange if people didn’t die early after eating it.
Of course, Huang Dan was taken internally at first. Later, after many people died, he realized that Huang Dan was poisonous, and then it was changed to external application.
Even more exaggerated than Huang Dan, there is Huan Dan, which is to heat cinnabar to remove impurities and mercury, which is liquefied mercury, and becomes solid again when cooled.
When Su Jing was looking for ancient alchemy classics, she found two books, "Zhou Yi Shen Tong Qi" and "Bao Pu Zi".
Here is the refining method. Heat 15 parts of lead and 6 parts of mercury into a liquid state in a cauldron furnace. At this time, add firepower to let the mercury volatilize to form yellow elixir. At this time, mix the yellow elixir and 9 parts of mercury. The mercury is mixed, ground and pounded, put into a cauldron, sealed and heated to ensure that it does not deflate or crack. First use slow fire, then strong fire. Observe day and night, and adjust the temperature from time to time. The elixir finally refined is Huantan.
Finally, in order to make the baked elixir more shaped, better-looking and more delicious, you can also add cinnabar, saltpeter, glue made from leather, distiller's yeast, etc.
After repeated refining and successful transformation once, in 12 years, it can be refined into the Nine Turns of Returning Pill.
Ge Hong and other alchemists believe that the elixir will absorb the innate energy during the refining process. When it is completed in 12 years, the color will turn purple and the magical elixir will be completed.
People who take this elixir can directly ascend during the day.
When Su Jing first saw it, she also called him a good guy.
If you take this elixir, it is really possible to ascend in the daytime, but you will not go to the fairy world, but to the underworld.
Of course, Su Jing thought about it later and understood.
After all, it is normal for people from the Wei, Jin, Southern and Northern Dynasties to have such an understanding.
In any case, they truly pioneered chemistry.
Unfortunately, these things have not been systematically studied.
Inside the house at this time.
Zhu Biao and Zhu Ru also looked at Su Jing's alchemy operation outside the house with great curiosity.
The matter of refining elixirs for immortality is quite attractive.
"Brother, does Master Su really want to refine elixirs for immortality?"
Zhu Xi asked Zhu Biao.
Zhu Biao shook his head and said: "Master Su has already told me that he did not make elixirs to seek immortality, and refining elixirs cannot lead to immortality."
If it hadn't been for Su Jing's accurate answer, Zhu Biao wouldn't be so calm at the moment.
Zhu Rui asked doubtfully: "Then why does Master Su want to refine elixirs?"
"I don't know, but Master Su must have a deep meaning in doing this."
Zhu Biao replied.
He was also quite curious in his heart.
The things Su Jing created always made him feel extremely novel.
In the yard, Su Jing continued to increase the firepower.
In order to maintain the firepower of the alchemy furnace at a reasonable level, Su Jing directly added a blast box next to it.
It's not that Su Jing has never thought about building an incinerator of her own.
At first he was quite interested in designing it himself, but he was soon slapped in the face.
Not everything he could remember.
Pure theoretical knowledge can still be recalled with the help of memory in the mind.
Things like chemical reactors were used directly when he was in school in his previous life. He really didn't understand how to design and manufacture them.
Buying an alchemy furnace is the most direct and simple way.
As the temperature in the furnace continues to rise, green vitriol, or ferrous sulfate, begins to react, using oxygen as the oxidant, and quickly generates iron oxide and sulfur trichloride.
However, because of the closed space in the furnace, more ferrous sulfate itself undergoes an oxidation-reduction reaction, generating iron oxide and gaseous sulfur dioxide and sulfur trioxide.
Sulfur trioxide and water vapor are condensed simultaneously to obtain sulfuric acid.
According to records in ancient books, the sulfuric acid obtained in this way is called green vitriol oil.
Su Jing also did not expect that she, a person who had studied modern chemistry, would prepare sulfuric acid according to ancient books.
After one operation, Su Jing finally stopped.
When the temperature of the stove dropped, Su Jing opened the stove lid.
"Dan" appeared in front of his eyes. Of course, it was not as round as jade, but a pile of strange-shaped residue.
Su Jing was not surprised. This was a normal chemical reaction. How could any elixir appear?
But those green vitriol oils were what he wanted most.
Su Jing carefully collected them and put them into glassware, but Su Jing was a little disappointed.
Because the sulfuric acid obtained is not pure, the amount is quite small.
It seems that if you want to prepare sulfuric acid on a large scale, it is not feasible to rely solely on this alchemy technique.
"Master Su, have you mastered your elixir?"
Zhu Biao and Zhu Ru came out of the house and asked Su Jing.
Su Jing smiled and said, "You'll know just by looking at it yourself. Just be careful to stay away and look."
Zhu Biao and Zhu Ru couldn't wait to come to the alchemy furnace and curiously looked at the contents of the alchemy furnace.
Zhu Biao and Zhu Zhu didn't really believe in the idea of refining elixirs to seek immortality.
But this does not hinder their curiosity.
Alchemy is still a very mysterious knowledge.
However, when they saw the scene inside the alchemy furnace, Zhu Biao and Zhu Ru were stunned on the spot.
"Master Su, why don't you have any elixir?"
Zhu Ru turned around and asked Su Jing.
"Aren't those just pills?"
Su Jing replied.
Is this the elixir?
Zhu Biao and Zhu Xi looked at the residue-like things at the bottom of the furnace, and they really couldn't connect them with the elixir.
Alchemy is all about this kind of thing?
The two looked at each other with puzzled expressions on their faces.
"Master Su, what on earth is going on?"
Zhu Biao came to Su Jing and asked seriously.
Su Jing was still observing the little bit of sulfuric acid she prepared.
"Nothing happened. The result of alchemy is just like this. I am not mistaken, and you are not mistaken either."
Su Jing said calmly: "You told me that Alchemy Immortality is a lie. Why, are you unable to accept the truth after seeing it?"
this.
Zhu Biao didn't know what to say for a while.
Regarding the matter of refining elixirs for immortality, Zhu Biao believed that it was impossible based on scientific knowledge.
But Zhu Biao couldn't accept that he could not even produce a single elixir.
After all, refining the elixir for immortality needs to be taken internally.
Zhu Biao never believed that those alchemists could eat this thing themselves.
Some people make elixirs for the emperor, so they can't present them to the emperor.
The emperor was superstitious about alchemy and immortality, but that doesn’t mean he was a fool!
Su Jing saw the confusion on Zhu Biao's face and said with a smile: "It seems that Niu Yi, you are still quite confused. Then go out and buy some materials for me."
"I want saltpeter, pig skin, and distiller's yeast."
Su Jing made a list directly to Zhu Biao.
Since Zhu Biao feels something is wrong, then make a suitable elixir and give it to him to take a look.
"Yes, Master Su."
Zhu Biao nodded immediately, took the money and set off.
Zhu Jing looked at Su Jing who was observing the sulfuric acid and asked: "Master Su, this seems to be your purpose, right?"
Su Jing nodded and said: "Yes, this green vitriol oil is exactly what I want, but it's a pity that the quantity is too small."
The importance of sulfuric acid is too great.
In Su Jing's previous life, sulfuric acid was known as the mother of the chemical industry.
As the most basic and important chemical raw material in chemistry, it is widely used in chemical fertilizers, pesticides, metallurgy, petroleum, chemical fibers, dyes, daily necessities, national defense and other fields.
Although for the current Daming Dynasty, sulfuric acid is not that critical.
But only with a foundation can development be possible.
"Green vitriol oil?"
Zhu Ju looked at the sulfuric acid in the glass bottle curiously and felt that Su Jing seemed to know everything.
Soon, Zhu Biao bought everything Su Jing needed.
Su Jing also directly followed the alchemy method in the book and started formal alchemy again.
Of course, Su Jing directly omitted those repeated processes in the book.
I am not really making elixirs, I am just showing the effects to Zhu Biao.
It didn't take long for Su Jing to actually refine the "golden elixir" in the book.
"Niu Yi, this is the so-called golden elixir."
Su Jing picked up the golden elixir with a clip and put it into the glass.
After all, it is something rich in heavy metals, so it is best not to touch it directly with your hands.
Even the mouth of the glass was covered with brown paper.
Safety is always the first priority in chemistry.
Zhu Biao looked at the golden elixir in the glass, couldn't help but find Su Jing's classics, and carefully identified it based on the description.
It turns out to be exactly the same.
"Master Su, I don't think it takes a long time to refine the golden elixir in this book. Why did you finish it so quickly?"
Zhu Biao asked Su Jing.
The elixir-making time recorded in the elixir book often takes several months, and some even take several years or more.
For Su Jing, a few hours is enough.
Really fast.
Su Jing smiled and said: "Niu Yi, although the time is short, the efficacy of my golden elixir has not been compromised. If you take it, you will be able to return to the west quickly."
Return to the West!
Hearing Su Jing's words, Zhu Biao's expression suddenly changed.
He didn't believe in the claim that golden elixir could lead to immortality.
But this was the first time he had heard that the golden elixir would lead to death after eating it.
"Master Su, what you mean is that this golden elixir is poisonous?"
Zhu Biao asked Su Jing carefully.
Su Jing replied: "Niu Yi, didn't you look at the ingredients I added? Do you think this thing is really edible?"
As she spoke, Su Jing shook the cup in her hand towards Zhu Biao.
The golden elixir dripping on the bottom of the cup rotates and sparkles.
Just looking at it, it really looks like that.
"It should be inedible."
Zhu Biao shook his head.
The messy things I bought didn’t look like they could be eaten no matter how much I thought about them.
"Okay, there is alchemy, but the golden elixir is definitely useless. Don't think so much."
Su Jing said to Zhu Biao: "Study hard. When you are good at physics, I will teach you this. By the way, this is called chemistry."
"Students understand."
Zhu Biao nodded.
The courtyard once again returned to its previous state, with Zhu Biao and Zhu Ru studying.
Su Jing did not continue to refine alchemy, but studied the structure of the alchemy furnace.
At the same time, he was also recalling the chemistry knowledge he had learned. To prepare sulfuric acid, he had to use another more efficient method.
…
Inside the Forbidden City.
All the princes were still facing the big bronze tripod, even Zhu Xi was no exception.
Although he has tried to no avail, his brothers haven't given up yet. It doesn't look good for him to run away by himself.
The Hall of Supreme Harmony is where the ministers attend morning court every day, so the behavior of the princes naturally falls in their eyes.
There must have been whispers in private, but everyone had a tacit understanding, and no one took the initiative to provide assistance to the princes.
"Third brother, fourth brother, I think this is simply impossible. Let's go. There is no need to waste time here."
Zhu Xi said to Zhu Fan and Zhu Di.
He is the type who retreats on his own but still wants to bring others along.
If you can't live up to your reputation alone, you need someone to help you.
As for why he didn't find Lao Liu and Lao Qi, Zhu Fang also wanted to lose face.
These two younger brothers also wear crotchless pants.
"Second brother, I still want to think of another way."
Zhu Fan said to Zhu Ping.
"Second brother, third brother and I have the same idea."
Zhu Di also said to Zhu Xi.
The attitude of these two people made Zhu Xi feel quite uncomfortable. It didn't matter whether he left or not.
"Fourth brother, do you have any ideas?"
Zhu Fan asked Zhu Di beside him.
Even though Zhu Di was poor at studying, Zhu Fan never looked down on his younger brother.
Those military commanders all spoke highly of Teacher Zhu Di.
Not only is he simply wielding swords and guns, Zhu Di is also very talented in strategies for changing military formations.
In other words, Zhu Di is not as simple and brainless as Zhu Ping.
"Second brother, I wonder if I can use a catapult to lift this cauldron."
Zhu Di expressed his thoughts.
Catapults are quite powerful weapons in siege warfare.
Such a big stone can be thrown directly a very long distance.
Zhu Fan thought for a while and said: "Third brother, as for the catapult, I'm afraid it's not enough for you to tighten it alone. What my father said is our strength alone. You can find a ready-made catapult directly, but you can't have it." Soldiers help.”
As soon as Zhu Fan said this, Zhu Di immediately realized that his method was not feasible.
"Where's the second brother? Does the second brother have any ideas?"
Zhu Di asked Zhu Fan.
Zhu Fan shook his head and said: "I haven't thought of a solution yet, but I think it's not impossible for our father to give us this difficult problem. Maybe our father already knows that someone can do it, so he gave it to us."
The third child's thinking was quick. As soon as he said these words, even Zhu Xi realized something.
"Third brother, do you mean Mr. Su?"
Zhu Di looked at Zhu Fan and expressed his guess.
