After five years of teaching support, Daming became an empire on which the sun never sets.

Chapter 198 Blast Furnace Alchemy
"It doesn't matter whether you agree or not, the facts are already there." Qin Yu said indifferently, "It is an indisputable fact that the technique of Qihuang cannot cure bacterial infections, and tuberculosis has become a problem through the ages."

"That's because they haven't met a real master." Lao Zhang said.

"I didn't expect that you were still a Qihuang Bing." Qin Yu said, "If you are telling the truth, Huo Qubing and Empress Ma would not have died in those years. Those who treated Huo Qubing and Empress Ma were imperial physicians, representing Qihuangzhi at that time. The highest level of art. Even if the imperial doctor can't cure it, others will not be able to. Don't tell me what masters say in the folk."

"It's true." Lao Zhang said, "But the master I'm talking about is not a master of Qi Huang's technique, but a master of poison medicine!"

"Master poison doctor?" Qin Yu smiled.

Thinking that he was a whimper, he made up a new set of reasons.

In fact, Qin Yu takes a dialectical view on Qihuang technique and Western medicine.

I think both have their own advantages, and they are neither ignorant nor ignorant.

But I didn't expect this old Zhang, who is a little suspicious of brainless whistle blowing, to actually say that a master of poison can treat bacterial infections.

And the profession of poison doctor seems to be made up by him.

"The penicillin you mentioned in class is actually a bit similar to the poison used by poison doctors to treat diseases." Lao Zhang said, "Penicillin allergy can easily lead to death of patients, and it is extremely dangerous for expert poison doctors to fight poison with poison."

"You said that too much penicillin will cause drug resistance, and the same is true of the virus used by poison medicine to treat diseases."

"Just blow it for me." Qin Yu said.

"If you don't believe it, forget it." Lao Zhang said, "They have always extracted highly poisonous toxins from poisonous snakes, poisonous spiders, poisonous centipedes and other highly poisonous things to treat diseases. So they cured some intractable diseases, Worse than your penicillin."

"But to be honest, the poison doctor has never extracted toxins from mold."

"The extraction of toxins from molds that you just proposed in class has great reference value for poison doctors."

"It's like a wake-up call for them. It has the effect of a morning bell and a twilight drum.

"That's why Laodao just said that listening to your lectures will often yield unexpected results."

"Continue to blow, the cowhide will go to the sky." Qin Yu obviously didn't believe it.

"Don't believe it." Lao Zhang didn't care.

"By the way, I see that you are sneaking around these days and often come back from the back mountain. What are you doing?" Qin Yu asked, changing the subject.

"No, nothing." Lao Zhang's eyes were obviously dodging.

"The more you are like this, the more curious I am." After Qin Yu finished speaking, he was about to walk towards the back mountain, "It's fine now, I'll go take a look."

"Just watch it if you want, anyway, you won't be able to hide it in the end." Lao Zhang said helplessly, and then followed.

Not long after, the two came to the back mountain one after the other.

In a valley, the first thing that caught Qin Yu's eyes was an earthen furnace pit.

The furnace pit is more than three meters high. The surrounding area is covered with yellow mud, and the inside is covered with bricks. More than half of the project has been completed.

There is a huge bronze furnace cauldron in the middle, which looks like a legendary Taoist alchemy furnace.

There are shovels, steel drills, hoes and other tools nearby, which seem to be borrowed from villagers' homes.

"You did this all by yourself?" Qin Yu was amazed.

He is a 80-[-]-year-old man, but he can complete such a large project by himself! ?
He asked, "Why are you secretly building a blast furnace here? Do you want to make iron in a private blast furnace and melt the furnace inside?"

He couldn't help but wonder if the alchemy furnace inside was stolen from a certain gym.Then I want to melt it in a blast furnace and sell it for money.

In Qin Yu's mind, Lao Zhang is an old liar.

"No, no, it's not that I have nothing to do when I'm full, why do I make iron in a blast furnace?" Old Zhang Wenyan smiled awkwardly,
It was obvious that Qin Yu did not suspect that he was stealing the alchemy furnace, and said, "Good alchemy furnace, what am I melting it for? It's a treasure."

"Treasure? I didn't see it." Qin Yu said.

"I have eyes but I don't know gold inlaid jade." Lao Zhang rolled his eyes at him.

"Then tell me, you didn't build this blast furnace to make iron, but what did you want to do?" Qin Yu asked.

"Old Dao, I just listened to the blast furnace ironmaking class taught by Mr. some time ago. I learned that the temperature in the blast furnace is higher, and then I had a whim and wanted to use the blast furnace ironmaking method to make alchemy." Lao Zhang said.

"Use a blast furnace to make alchemy?" Qin Yu was dumbfounded, "You really dare to think about it."

"By the way, you can still make alchemy? Isn't it a new deception method you came up with?"

"Look at what you said. When a Taoist priest, who can't make a pill?" Lao Zhang said, "As for you always think I'm a liar, hehe, you'll be happy."

"Even if you really know how to make alchemy, you can't use a blast furnace to make it." Qin Yu said, "The temperature inside the blast furnace is at least [-] degrees Celsius."

"You are a layman, and I don't blame you for not knowing alchemy." Lao Zhang said, "Do you think alchemy is an easy task? To tell you the truth, alchemy is an extremely profound knowledge."

"The old Taoist alchemy technique belongs to the Zhonglu School. Alchemy is divided into [-] main points, including Dao, heaven and earth, sun and moon, four o'clock, five elements, water and fire, dragon and tiger, elixir, lead and mercury, etc., which are divided into twelve categories. …”

"Profound knowledge? That would be disrespectful." Qin Yu was too lazy to listen to him talking about those mysterious and mysterious things, and hurriedly interrupted him, said.

"If you don't like to listen, I'm too lazy to talk." Lao Zhang said.
Suddenly sighed: "I can't understand you more and more."

"Say you don't know anything, but you can write some chemical equations for the reaction of lead and mercury, so that Laodao has benefited a lot in alchemy. Say your alchemy knowledge is much higher than mine, you can't even feel anything. interest."

Benefit a lot?

Qin Yu remembered it. Old Zhang did come to him from time to time to ask him for some chemical knowledge, most of which were about the reaction of heavy metals. At that time, Qin Yu didn't pay much attention to it. He thought he was diligent and eager to learn, so he taught him patiently.

Unexpectedly, this old man actually used chemistry in alchemy, which was beyond his expectations.

Not doing business!Qin Yu just wanted to say that to him now.

This old man Zhang is similar to the village chief Huang, and he is not doing his job properly.

One uses chemical knowledge for alchemy, the other leaves the village chief's business and prefers to study history.

These two are kind of weird.

It is really a hundred kinds of rice to support a hundred kinds of people.

"I used to refine a special kind of pill, it took decades and countless resources, and I didn't succeed once." Lao Zhang said, "Now I have found the reason, that is, the material ratio is not right, Plus the temperature isn't enough."
