Daming: Old Zhu, we agreed not to rush!

Chapter 186 The Golden Pill Calcined in the Furnace Fire, Do You Dare to Eat It!
Lishui County.

The alchemy furnace was transported to the yard, and Su Jing's alchemy life naturally began.

According to the ancient method, Su Jing used green vitriol to make alchemy.

In order to avoid the impact of toxic gas on health, Su Jing specially made some glass containers to hold raw materials.

Green vitriol is actually natural ferrous sulfate.

Su Jing put the green vitriol in the alchemy furnace, added an appropriate amount of rice vinegar, covered the alchemy furnace, and directly burned it under the fire.

The fire was burning vigorously, and the small courtyard was also very warm.

But Su Jing didn't have Zhu Biao and Zhu Wei staying in the yard to study.

After all, you are doing chemistry, so you still have to pay attention to your health.

The ancient alchemists practiced alchemy in some kind of airtight room at every turn, they really messed with themselves.

Poor ventilation conditions can easily cause the accumulation of harmful gases.

The lifespan of the ancient alchemists was actually not long.

Although there are many classics that record the longevity of alchemists, such as the legendary alchemist and the immortal doctor Ge Hong.

Although it is recorded that he lived to be 81 years old, Su Jing has always been skeptical about this.

After all, this ancient alchemy technique, to put it bluntly, is to refine heavy metal enrichment.

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 did not die early after eating it.

Of course, Huang Dan was taken internally at first, but after many people died, they also realized that Huang Dan was poisonous, and then it was changed to external application.

Even more exaggerated than Huang Dan is Huan Dan, which is to heat cinnabar to remove impurities and mercury, that is, mercury liquefies, and becomes solid again when cooled.

When Su Jing was looking for ancient alchemy classics, he found two books, "Zhouyi Cantongqi" and "Baopuzi".

Here is the refining method. Heat 15 parts of lead and 6 parts of mercury in a cauldron to form a liquid. Mercury is mixed, ground and smashed, put into the cauldron, sealed and heated, making sure that it does not leak or crack, first simmers, then simmers, observes day and night, adjusts the temperature from time to time, and finally refines the elixir that is the elixir.

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 and so on.

Repeated refining, one successful transformation at a time, so that after 12 years, it can be refined into a nine-turn red pill.

Ge Hong and other alchemists believe that the elixir will absorb the innate qi during the refining process, and after 12 years of success, the color will turn purple, and the magic elixir will be completed.

Those who take this elixir will be able to ascend directly in the daytime.

When Su Jing first saw it, she also called it a good guy.

If this elixir is taken, it is really possible to ascend in the daytime, but it is not the fairyland, but the underworld.

Of course, after Su Jing thought about it, he could understand it.

After all, it is normal for Ge Hong to have such an understanding during the Wei, Jin, Southern and Northern Dynasties.

In any case, they are truly pioneering chemistry.

Unfortunately, these things have not been systematically studied.

In the house at this time.

Zhu Biao and Zhu Wei also watched Su Jing's alchemy operation outside the room quite curiously.

The matter of alchemy and longevity is quite attractive.

"Brother, does Master Su really want to make alchemy for longevity?"

Zhu Xi asked Zhu Biao.

Zhu Biao shook his head and said: "Master Su has already told me that he does not make alchemy for longevity, and he does not make alchemy for longevity."

If it wasn't for Su Jing's accurate answer, Zhu Biao wouldn't be so calm at this moment.

Zhu Wei asked suspiciously, "Then why did Master Su make alchemy?"

"I don't know, but Master Su must have a deep meaning in doing this."

Zhu Biao replied.

His heart is also quite curious.

The things Su Jing created always made him feel extremely novel.

In the courtyard, Su Jing continued to increase the firepower.

In order to keep the firepower of the alchemy furnace at a certain level, Su Jing directly added a blower box beside it.

It's not that Su Jing never thought of building an incinerator by himself.

At first, he was quite interested in planning to design it himself, but soon he was slapped in the face.

Not everything he can remember.

Pure theoretical knowledge, relying on the memory in my mind, can still be recalled.

Like the chemical reactor, he used it directly when he was in school in his previous life. He really didn't understand how to design and manufacture it.

Buying an alchemy furnace is the most direct and simple way.

As the temperature in the Dan furnace continues to rise, green vitriol, that is, ferrous sulfate, begins to react, using oxygen as the oxidant to quickly generate iron oxide and sulfur trichloride.

However, because of the closed space in the furnace, more ferrous sulfate itself undergoes redox reactions to generate iron oxide and sulfur dioxide and sulfur trioxide.

Sulfur trioxide is condensed with water vapor at the same time, and sulfuric acid is obtained.

According to the records in ancient books, the sulfuric acid obtained in this way is called green vitriol oil.

Su Jing also did not expect that a person who accepted the study of modern chemistry would prepare sulfuric acid according to ancient books.

After one operation, Su Jing finally stopped.

When the temperature of the furnace dropped, Su Jing opened the furnace cover.

"Dan" appeared in front of his eyes, of course it was not round and jade-like, but a pile of oddly shaped residues.

Su Jing was not surprised, this was a normal chemical reaction, how could there be any kind of elixir.

But those green vitriol oils are what he wants most.

Carefully collected it and put it in a glass container, but Su Jing was a little disappointed.

Because of the obtained sulfuric acid, not to mention the impurity, the amount is quite small.

It seems that this alchemy alone is not feasible for large-scale production of sulfuric acid.

"Master Su, have you trained your elixir yet?"

Zhu Biao and Zhu Wei came out from the house and asked Su Jing.

Su Jing smiled and said: "You can see it yourself, pay attention to look at it from a distance."

Zhu Biao and Zhu Wei couldn't wait to come to the alchemy furnace, and checked the contents of the alchemy furnace curiously.

Neither Zhu Biao nor Zhu Wei believed in alchemy for longevity.

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 Xi were stunned on the spot.

"Master Su, why is there no pill?"

Zhu Wei turned his head and asked Su Jing.

"Aren't those pills?"

Su Jing replied.

Is this the medicine pill?
Zhu Biao and Zhu Wei looked at the residue-like things at the bottom of the furnace, and they really couldn't connect them with the elixir.

Alchemy, is this what is practiced?

The two looked at each other with puzzled expressions on their faces.

"Master Su, what is going on?"

Zhu Biao came to Su Jing and asked seriously.

Su Jing is still observing the little bit of sulfuric acid that she prepared.

"It's nothing wrong, the result of alchemy is like this, I'm not mistaken, and you are not mistaken."

Su Jing said indifferently: "Alchemy Changsheng, you told me it's fake, why, is it unacceptable to see the truth instead?"

This.
Zhu Biao didn't know what to say for a while.

For the matter of alchemy and longevity, Zhu Biao believes that this is impossible based on scientific cognition.

However, Zhu Biao couldn't accept that even a pill could not be produced in alchemy.

After all, alchemy for longevity needs to be taken internally.

Zhu Biao couldn't believe that those alchemists could eat this thing by themselves.

Some of them made alchemy for the emperor, so they couldn't present this to the emperor.

The emperor is superstitious about alchemy for longevity, but it doesn't mean he is a fool!

Su Jing saw the doubt on Zhu Biao's face, and said with a smile: "It seems that Niu Yi still has doubts in your heart, so you go out and buy some materials for me."

"I want saltpeter, pigskin, and distiller's yeast."

Su Jing directly made a list to Zhu Biao.

Since Zhu Biao felt that something was wrong, let him have a look at the right medicine.

"Yes, Master Su."

Zhu Biao nodded immediately, took the money and set off.

Zhu Wei looked at Su Jing who was observing the sulfuric acid and asked: "Master Su, this seems to be your purpose?"

Su Jing nodded and said: "That's right, this green vitriol oil is exactly what I want, but it's a pity that the amount 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 fiber, dyes, daily necessities, national defense and other fields.

Although for the current Daming, sulfuric acid is not that critical.

But with the foundation, there is the possibility of development.

"Green oil?"

Zhu Wei looked curiously at the sulfuric acid in the glass bottle, and felt that Su Jing seemed to understand everything.

Soon, Zhu Biao bought back everything Su Jing needed.

Su Jing also directly followed the method of alchemy in the book, and restarted the formal alchemy.

Of course, Su Jing directly omitted those repeated processes in the book.

I don't really make alchemy, I just show Zhu Biao the effect.

It didn't take too 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 pill with a clip and put it into the glass.

After all, it is something rich in heavy metals, so it is better not to touch it directly with your hands.

Even the mouth of the glass was covered with brown paper.

Safety is always the top priority in chemistry.

Zhu Biao looked at the golden pill in the glass, and couldn't help but find Su Jing's classics, and carefully identified them according to the description.

It turned 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 refine it so quickly?"

Zhu Biao asked Su Jing.

The alchemy time recorded in the alchemy book is often several months, and some even take several years or more than ten years.

For Su Jing, a few hours is enough.

It's really fast.

Su Jing smiled and said: "Niu Yi, although the time is short, the effectiveness of my golden elixir is not compromised, and I can guarantee that I will return home quickly after taking it."

Go west!

Hearing Su Jing's words, Zhu Biao's face suddenly changed.

He doesn't believe the saying that Jindan can live forever.

But it was the first time he had heard of this golden elixir that would go away after eating.

"Master Su means 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 stuff is really edible?"

Saying that, Su Jing shook the cup in his hand towards Zhu Biao.

The golden elixir dripped at the bottom of the cup, shining brightly.

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 seem like they could be eaten in my stomach no matter what I thought.

"Okay, there are alchemy techniques, but golden pills are definitely useless, so don't think too much about it."

Su Jing said to Zhu Biao: "Study hard, I will teach you this after you finish physics. By the way, this is called chemistry."

"Students understand."

Zhu Biao nodded.

The small courtyard returned to its previous state again, and Zhu Biao and Zhu Huan studied.

And Su Jing did not continue alchemy, but studied the structure of the alchemy furnace.

At the same time, he was also recalling the chemical knowledge he had learned. The preparation of sulfuric acid had to adopt 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 fail, his younger brothers have not given up yet. It is really not good for him to slip away by himself.

The Hall of Supreme Harmony is the place where the ministers go to the morning court every day, and the behavior of the princes naturally falls into their eyes.

There must have been whispers in private, but everyone also had a tacit understanding, and no one offered 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 Xing said to Zhu Xun and Zhu Di.

He's the type to back off on his own, but to pull others along.

If you can't save face by yourself, you need someone to accompany you.

As for why he didn't look for Lao Liu and Lao Qi, Zhu Xi also wanted to face it.

These two younger brothers still wear crotch pants.

"Second brother, I still want to think of a way."

Zhu Xun said to Zhu Xun.

"Second brother, I think the same as third brother."

Zhu Di also said to Zhu Xi.

The attitude of these two people made Zhu Xi quite uncomfortable. He didn't want to leave now, and it didn't matter if he didn't leave.

"Fourth brother, do you have any ideas?"

Zhu Yan asked Zhu Di who was beside him.

Don't look at Zhu Di who is poor at studying, but Zhu Yan has never underestimated his younger brother.

Those generals all spoke very highly of Mr. Zhu Di.

Not just simply wielding knives and guns, Zhu Di is also very talented in the strategy of changing the military formation.

In other words, Zhu Di is not as simple and brainless as Zhu Xi.

"Second brother, I wonder if it is possible to use a catapult to lift this tripod."

Zhu Di expressed his thoughts.

Catapults are quite powerful weapons in siege battles.

Such a large stone can also be thrown directly to a very long distance.

Zhu Bian thought for a while and said: "Third brother, if you are talking about the catapult, I am afraid that your strength alone is not enough. What the father said is our strength alone. You can directly find a ready-made catapult, but you can't have it. Soldiers help."

As soon as Zhu Yan said this, Zhu Di immediately realized that his method was not feasible.

"What about the second brother? Does the second brother have any ideas?"

Zhu Di asked Zhu Bian.

Zhu Yan shook his head and said: "I haven't thought of a solution yet, but I think it's not impossible for the emperor to ask us this problem. Maybe the emperor already knows that someone can do it, so he gave it to us."

The youngest's thinking is quick, and when he said this, even Zhu Xi realized something.

"Third Brother, you mean Mr. Su?"

Zhu Di looked at Zhu Yan and expressed his guess.
