Shuang Daqin comparison, no comparison, no harm

[Hu Hai]: With such a natural disaster, can your Daqin survive safely?

Hu Hai asked curiously.

If only the plague could have been avoided.

That would be outrageous!

Suddenly.

Everyone in the original Daqin was looking forward to the reply of the people who became Daqin.

[Ying Zheng]: The Qin state also has a plague. However, there is Ze’er….

Hear this.

Everyone in Yuan Daqin was cold in their hearts.

Don’t!

Zhao Ze has a way to crack the plague?!

The picture of the larger Qin unfolds.

The same.

Above the main hall.

Lees recounts of plague outbreaks in several neighboring countries.

Quite a few people have died.

He was afraid.

The plague will also come to the Qin Kingdom, causing the Qin State to be hit hard.

The same approach has been taken.

“Notify the border officials to close the country’s doors and prohibit everyone from entering and leaving the Qin Kingdom!”

“If someone is infected, isolate on the spot!”

“Yes! King! ”

Lees turned his head and went to deliver the message.

At that time.

Zhao Ze, who is already nine years old, looks even more heroic.

Chang is also more and more similar to Yingzheng.

He who was talking to the palace maid suddenly received a prompt from the system.

New missions are coming!

“The plague?”

Zhao Ze’s face froze, and he pushed the palace maid away to prepare to go to the Industrial Construction Institute.

The little palace maid reluctantly took Zhao Ze’s hand.

But I can’t hold it.

“Gongzi, where are you going?”

She asked, scratching her head.

“You go back, I’ll go to the Industrial Construction Institute!”

Zhao Ze left in a hurry.

When the craftsmen of the Industrial Construction Institute saw Zhao Ze appear, they were shocked in their hearts.

Because.

Zhao Ze only likes to hunt and play on weekdays, or he hangs out with beautiful palace maidens.

Rarely come to such boring places.

Every time it appears.

It must show that Zhao Ze has good things to invent.

“Changgongzi!”

“Why did you come to the Institute, eldest son?”

“Isn’t there another invention?”

The crowd immediately gathered around.

Really.

Zhao Ze immediately spoke.

“Bring limestone and fire soda!”

These two things are not unfamiliar in the Warring States.

Back in the Spring and Autumn period.

Lime has been used as a cementitious material.

It can change from slurry to solid, and can be doped with some other objects, which is cementitious material.

It is often used to patch up something.

For example, clay pots and the like.

Moreover.

In addition to lime mines, humans were able to extract limestone from shells.

The way to obtain it in nature is simple and crude.

Therefore.

The craftsmen of the Gongzao Institute are no strangers to lime, but the name is different.

Caustic soda.

Before it was first applied to the Warring States, it is impossible to study how long ago.

Ancient people would mine caustic soda.

Use it for laundry, good cleaning ability.

Even in the era of science and technology, the main raw material is caustic soda.

So.

When Zhao Ze shouted out these two things.

The craftsmen were not confused and immediately turned around to take it.

“Get some more pieces of fat!”

Zhao Ze said again.

The craftsmen were stunned.

Quicklime and fire soda are understandable, after all, they themselves are commonly used.

But…

What is fat for?

But.

The craftsmen did not dare to delay.

Someone immediately said, “Wait a minute, I’ll go ask the cook for a few pieces of fatty meat!” ”

Soon.

All materials are available.

In front of all the craftsmen.

Zhao Ze started the pot and poured the fat meat into the pot and stir-fried.

“Remember.”

“I’m going to teach you how to make soap.”

“The method is very simple, you will see it at a glance, and after you learn it, you will teach other craftsmen.”

Kung Fu of speaking.

A basin full of animal oil was boiled out by the heat.

After waiting for cooling, it turns into a milky white ointment.

Subsequently.

Zhao Ze threw quicklime into the fire and waited for a moment.

Seeing that the lime changed color, Zhao Ze took it out and threw it into clear water to mash it.

Wait for the impurities to settle to the bottom.

Zhao Ze carefully poured out the lime water.

Then.

Then crush the fire alkali into ash and sprinkle it with lime water.

The combination of the two emits some tiny bubbles.

Wait again for the impurities to settle to the bottom.

This gives a sodium bicarbonate solution, that is, soda.

At last.

Zhao Ze poured soda water into the pot to heat, dug another spoonful of animal fat and threw it in.

“Take something and stir it in it, remember, you can’t stop.”

“Change when you’re tired.”

“When the feeling can’t be stirred, it’s done.”

Finished explaining.

Zhao Ze took the opportunity to find a place to bask in the sun and doze off.

And everyone, look at each other.

I don’t understand what Zhao Ze is doing.

However, the craftsmen did not dare to slack, and frantically stirred for two hours.

Until he felt that he couldn’t stir, he called Zhao Ze back.

Glanced at the grease in the pot.

Zhao Ze was overjoyed in his heart.

It’s done!

The craftsman was ordered to pour the grease into the basin.

Wait for cooling to set.

It is then cut into pieces with a knife.

“It’s called soap!”

Picking up a piece, Zhao Ze introduced.

“Soap can be used to wash clothes, but also to wash hair, face, and hand!”

“After doing farm work, you can wash your hands after you go out.”

“Soap can decontaminate and sterilize.”

“If you wash your hands and face with soap, it will be difficult to catch the plague again.”

Between words.

Ying Zheng, who rushed to hear the news, saw the soap in Zhao Ze’s hand at a glance.

“Ze’er!”

“The widow heard the palace maids say that you hurried to the Industrial Construction Institute.”

“The widow knows that you have something new!”
