Da Qin: Give Ancestral Dragon the elixir of death at the beginning!

He Chao had long expected that Ying Zhenghui would be a reflection of this, and said disdainfully:

"Of course, the color and purity of ordinary salt are not as high as those of my cottage

The salt in my cottage is obtained after purification with brine salt. "

"Salt purification? You still know how to purify? "

When Ying Zheng heard this, he immediately stood up from the ground and asked incredulously.

Meng Tian was also shocked in his heart, and looked at He Chao in shock.

To know,

Nowadays, there are still hundreds of people in Daqin who can't afford to eat well salt

And go buy cheap brine salt to eat.

Halogen salt is the crystalline body that naturally condenses in saline-alkali land after being exposed to wind and sun.

This crystalline has not been purified

It contains a variety of impurities that are harmful to the human body

If it weren't for the last resort, no one would eat it.

However, because of its backward technology, Daqin has no way to purify the brine salt into refined salt

The high purity of well salt is simply not affordable for ordinary people.

The various Yankues and salt wells in the territory of Daqin are the same as copper and iron smelting

It is controlled by the government, and private individuals are not allowed to buy and sell at all.

After all, salt and iron are the foundation of the state and an important source of taxes for the imperial court.

Although there is no shortage of salt in Daqin, various salt mines in Daqin are common

But even though the government monopolized the trade in salt and iron, there was still a shortage of edible salt

This edible salt is still a precious thing in Daqin.

The root cause of this lies in

The government has not mastered the method of purifying the brine salts with high impurity content

As a result, there are countless salt mines in Daqin

But hundreds of people can't eat salt.

And now He Chao actually said that he knows the method of salt purification

Isn't that...

Thinking of this, Ying Zheng swallowed his saliva vigorously

I couldn't wait to look at He Chao and asked

"Master He, do you really know the method of purification?"

"Well, is the purified refined salt poisonous?"

He Chao couldn't help but roll his eyes, and couldn't help but ask:

"How can it be poisonous? If it's poisonous, will I give it to my villagers? "

"Haha, it's good to be non-toxic!"

"Master He Zhai, since your refined salt is purified from brine salt

It must be cheap, right? "

After Ying Zheng listened, he asked with a smile.

The corners of He Chao's mouth pursed, patted his chest and said:

"That's nature, the salt purified by the owner of this village

Every common person in Daqin can afford to eat! "

"Haha, it's non-toxic and cheap, it's really good salt!"

"He Zhai Master, if you take out the refined salt in your cottage and sell

it

You've done a great job again! "

Salt is a necessity in the daily life of the people of Daqin, and every common person must eat salt

If you don't eat salt for a long time, it can even cause serious consequences to your body.

Because everyone has to buy salt to eat, the imperial court can rely on the monopoly system

A large amount of taxes were collected from the salt industry, which allowed the imperial court to obtain a large amount of wealth.

And now He Chao has mastered the method of purifying the halide into refined salt

The importance of this cannot be overstated!

Thinking of this, Ying Zheng and Meng Tian looked at He Chao with burning eyes

The light in his eyes flickered.

"Let's talk about this then, it's not too early

I'm going to school, please! "

He Chao replied lightly, and after speaking

Just turn around and walk in the direction of the school.

Seeing the back of He Chao's departure,

Ying Zheng hurriedly patted Meng Tian's shoulder on the side and said

"Lao Meng, let's take a look at the school too."

After speaking, Ying Zheng followed excitedly.

At this moment, Ying Zheng is becoming more and more interested in He Chao.

Ever since he came to this cottage,

He saw many things from He Chao that amazed him

From the very beginning, unparalleled medical skills, high alcohol, economic theory, paper

As well as seeing high-purity refined salts today,

He Chao is like a mystery, constantly attracting Yingzheng.

Take out any of these things,

are all existences that can cause a sensation, but He Chao took them out one after another.

It is enough to prove that these things are revealed

It's just the tip of the iceberg on He Chao

There are bigger surprises on him waiting for Ying Zheng to discover.

Therefore, when he heard that He Chao was going to give a lecture at school again, Ying Zheng followed without saying a word.

He had a hunch that waiting for the content of He Chao's lecture would definitely surprise him.

Meng Tian saw that Ying Zheng turned around and left without saying a word

Some couldn't laugh or cry, so they hurriedly followed.

Soon, Ying Zheng and Meng Tian came to the school

walked outside the classroom where He Chao was lecturing.

At this time, He Chao had already opened the book and started lecturing.

"Students, today we are going to talk about a very serious topic - Western medicine!"

"Everyone opened the textbook of Western medicine, before starting to lecture

Let me first tell you about the difference between Western medicine and Chinese medicine. "

"The difference between Western medicine and Chinese medicine is mainly reflected in two aspects: research direction and way of seeing patients."

"The direction of Western medicine research is human anatomy, biochemistry, histology and embryology and other disciplines."

"Traditional Chinese medicine focuses on the harmony of yin and yang, and the image of meridians and veins."

"As for the way of seeing a doctor, the difference between the two disciplines is even greater."

"Traditional Chinese medicine emphasizes 'looking, hearing, inquiring, and seeing' to explore the cause of the disease

Western medicine, on the other hand, has heard inspection, auscultation, percussion, and palpation

Or with the help of tools and methods such as stethoscopes, blood pressure monitors, thermometers, etc

A systematic physical examination of the patient is performed to determine the cause. "

"These two medical disciplines are very different, and everyone must carefully screen them."

......

Ying Zheng and Meng Tian outside the classroom were directly stunned when they heard this!
