Chapter 251 Master and apprentice

Everything has arrived.

Li Ang looked around the raw materials and equipment in the room, took a deep breath, and raised his palm to release his mind.

Potassium antimony tartrate, also known as tart, is a powerful vomiting agent and antiparasitic drug.

It can disturb the body of Schistosoma worm, causing it to lose its muscle adsorption function, fall off from the blood vessel wall, be swept into the liver by the blood flow, and be eliminated by the human immune system in the liver.

In addition, potassium antimony tartrate can also affect the energy supply of insects, affect the reproductive system of insects, and have a powerful killing effect on schistosomiasis, filaria, etc.

"First of all, it's antimony..."

Antimony was called Lian Tin in Yu State, and it was used to dopant in copper to mint currency.

This batch of antimony transported from Tanzhou is of high purity.

After calcination, antimony white, that is, antimony trioxide can be obtained.

"Then, it's tartar..."

The precipitated tartar in wine contains about 50% to about 85% potassium bifid tartrate. It is decomposed and recrystallized by hydrochloric acid to obtain higher purity potassium bifid tartrate.

"Mixed the two..."

Put potassium bifidate and antimony trioxide into a round bottom flask in a weight ratio of 2 to 1, add distilled water, and install air condensation tube.

Using talismans and mind power, simulate a constant temperature magnetic stirrer, heated in a water bath, and the temperature is controlled close to boiling.

After the antimony trioxide is basically dissolved, filter while it is hot.

The obtained filtrate was concentrated by evaporation, cooled to crystallize, and allowed to stand.

Then, wash with a small amount of high concentration of ethanol and dry at a temperature of 80 degrees.

Finally, the white crystal is obtained.

“…”

Li Ang looked at the extremely purity of potassium antimony tartrate, but there was not much joy in his eyes.

He picked up the drug in silence, diluted it with five percent glucose injection, walked out of the secret room, came to the shed outside the hospital, and injected a small amount of antimony potassium tartrate into a sick cow infected with schistosomiasis.

Then take out the lyrics and stab it into the sick cow's body to monitor the physical condition of the sick cow.

He told Qiu Feng and others that he wanted to develop drugs and did not disturb him if there was nothing particularly important. Therefore, the courtyard was particularly quiet, with only the hard breathing of the plowing ox.

I don’t know how long it took, but Niansi finally got feedback.

In the body of the sick cattle, one after another, schistosomes twitched and atrophy, falling off the inner wall of the blood vessel, and being washed into the liver by blood, surrounded by inflammatory tissue and killed.

Countless pharmacists and schistosomiasis, whose prescriptions are helpless, have no ability to resist the special medicinal potassium antimony tartrate, and are killed one by one by one by one by the autumn wind swept away fallen leaves.

There was still not much joy on Li Ang’s face.

He got up and walked through the courtyard, pushed open the gate, and looked up at the cloudy sky.

Successful,

But the price is too great.

———

Taihu Lake was called Zhenze in ancient times, also known as Lize.

It was early spring, the lake water was rippling, and the willow trees on the shore sprouted tender buds, swaying in the wind.

The spring breeze is gentle, the grass is green, and the air is filled with the fragrant smell of grass and trees.

"Everyone must wear socks and gloves before they can get into the water! Did you hear that?"

"Be careful, schistosomiasis is pervasive and can even exist in the dew on the grass leaves. Even if you feel hot, you can't take off your gloves!"

"Dragons, every old ditch must be covered and new ditches must be dug again! Don't think that digging other people's canals has nothing to do with you. After spring plowing begins, the water system of the ditches is connected. If the snails in a place are not completely wiped out, a large area of ​​cultivated land will suffer!"

On the bank of the river, countless people who were mobilized were waving shovels and hoes, and digging ditches.

If we cannot kill snails and schistosomiasis on a large scale before spring plowing, all prefectures, counties, townships and towns along Taihu Lake will be attacked by a new round of water poisonous disease.

Rolling around—

A carriage drove by the lake road,

In the carriage, an old man named Situ Feng looked out the window through the curtains and chuckled.

"Haha. This momentum is really a battle against the sky and the earth, and man will defeat heaven..."

His eyes swept across the people who were sweating like rain on the shore, and a strange smile appeared on his face, "Yu Shi, do you know why I spread the epidemic in Yu Country?"

"Um?"

The white-haired boy sitting opposite the carriage thought that this was another trial for the teacher. He carefully considered the following words and slowly replied: "In order to defeat the State of Yu?"

"No, defeating Yu State was Zhao Ming's purpose, not ours."

Situ Xu said, "Think about it again."

"for..."

The boy named Yu Shi followed the teacher's gaze and looked at the people of Yu outside the window and replied hesitantly: "Observe the reactions of people under the epidemic?"

“It’s very close.”

Situ Xu smiled and said, "We spread the epidemic not to kill as many people as possible, but to observe human power.

You are an abandoned baby of Western descent that I picked up.

In our hometown, in the west, there was once a great empire called Romulus.

Romulus' territory and people are no less than those of Yu State. Romulus' scholars also advocate the way of rationality, just like the Academy.

Five hundred years ago, an unprecedented plague broke out in Romulus.

The patient has severe diarrhea, vomiting, swelling and sore throat, fever, thirst, ulceration of hands and feet, pus in the skin, and rash on his body peels off like fish scales.

From royal nobles to slaves and civilians, nearly ten million people died in the plague. The entire empire suffered a huge blow, the order was shaky, and the fire of civilization was almost extinguished."

Situ Yue said leisurely: "However, just when everyone thought that the Romulus Empire would fall and perish, the disease subsided.

The living people who stand up from the pile of dead bodies will no longer be infected with diseases, and the population will rise accordingly.

They cleared the corners of the city and built more complete public buildings. The farming and construction within the empire was more developed than in the past. There were roads passing through all places, and each city was open to commerce.

People reclaim wasteland, build manors, cut down thorny forests, and replace them with farmland.

The civilization of the empire is also more prosperous than in the past.

The death of the slave owner liberated a large number of slaves.

Past debts were erased, business redeveloped, thriving,

The college lowered the threshold and accepted more students.

The nobles feared the power in the dark and did not dare to act recklessly anymore. The upper class of society was degenerate and corrupt, and the atmosphere of arrogance and extravagance was solemn.

Even the seemingly endless war has to be stopped due to the lack of manpower.

A terrifying plague brought rebirth to the empire.”

Situ Xu sighed: "In the East, the same is true for everything.

The new kingdom, because it has cleared the accumulated shortcomings of the past, can re-establish order and quickly have strong national strength.

For example, the Han Empire, from the fact that Emperor Gaozu of Han was besieged by the Huns in Baideng Mountain to Emperor Wu of Han attacking the Huns and forcing him to move far north of the desert, it took only a few decades.

After the demise of the Western Han Dynasty and Emperor Guangwu unified the world again, the population of the empire increased again and the national strength quickly recovered.

Until the end of the Eastern Han Dynasty, the empire was unable to suppress the Yellow Turban Uprising due to its decay, and decided to drink poison to quench thirst, and ordered each county to recruit troops on its own, which eventually led to the demise of the Eastern Han Dynasty."

He stroked his beard and smiled, "The destruction of a great empire is often not due to foreign invasion.

But before this, the empire itself fell into a long-term rigidity.

The nobles were high above, and the wealthy families rallied in large numbers. The rich were all over the country, and the poor had no place to stand.

Scholars who are ambitious to change the status quo are forced to get involved in the officialdom and lose their motivation to move forward in a scheming.

The interests of all parties wrap around every corner of the empire like spiders. Everyone knows that the status quo is wrong, but everyone has no ability to change it.

The only lesson that humans can learn from history is that humans will never learn from history.

Unlike some people in Zhaoming, I don’t hate Yu Country.

On the contrary, I have a good impression of this huge empire that is somewhat similar to Romulus. If it weren't for the limitation of my identity, I would actually want to go to the academy in person and sit with the doctors there.

And I spread this plague not to destroy them,

It's more like...a kind reminder, a wake-up bell."
