Datang: I was exposed by Princess Changle

why?

Because Qin Shihuang attached great importance to medicine!

Where is Lin Xuan's hometown?

It's Xianting!

To be able to pass down the ancient prescriptions in the Immortal Court, this... can this be bad?

There may be a way to bring the dead back to life!

Lin Xuan smiled.

In fact, he also wanted to bring out some western medical skills, but the technology couldn't keep up.

Moreover, Chinese medicine has been passed down for thousands of years, so it may not be worse than Western medicine.

Foreigners are scrambling to ask for things that many Chinese people dismiss.

A medical book, 20 reputation points!

Much more expensive than serial novels like "The Legend of the Condor Heroes"!

Although these medical books have some similarities, they are all written by those medical masters with their own hard work.

As long as the promotion continues, Datang's fatality rate will be greatly reduced!

What should I do if I want to promote it?

Cultivate excellent doctors one by one!

In the future, it is even possible to open a medical clinic in every township.

There is no money to see a doctor, and no money to buy medicine.

If Chinese medicine can be popularized, it can also drive economic development.

The value of various traditional Chinese medicines can be tapped!

Then Lin Xuan took out another object, a boxy cuboid, red.

Li Shimin was very curious when he saw it!

He asked eagerly: "Qinglong King, tell me quickly, what is this thing?"

Lin Xuan explained lightly after hearing the words: "These square ones are red bricks, also known as bricks."

"Well, this red brick is not bad!" Li Shimin nodded happily upon hearing this.

Bricks actually existed during the Spring and Autumn and Warring States Periods.

During the Tang and Han Dynasties, brick-making technology and production scale, quality and fancy varieties all developed significantly, and they are known as Tang bricks and Han tiles in the world.

However, ordinary people still cannot afford bricks nowadays.

Because it uses blue bricks!

Although the quality of blue bricks is very good, the output is small and the cost is high.

Although it is very useful, it only serves the powerful class, so there is a saying of the blue brick compound.

The old houses preserved in ancient times are all made of blue bricks without exception.

Because the air permeability of the green brick is very good, and the water absorption is also very good.

Now some ancient green bricks with a history of hundreds of years can still be found in some ancient buildings!

However, it is still too expensive after all.

Lin Xuan used to live in a rural area for a while.

The largest enterprise in the village is a red brick factory.

Under the invitation of the factory manager to visit, Lin Xuan also probably knew the principle of firing red bricks.

The quality of red bricks is a bit worse, but they are cheaper, and the production speed is several times that of blue bricks.

For example, it's like the later generations performing brick splitting with bare hands.

Most of them are red bricks, and few people use blue bricks.

Just because the bricks are of good quality!

The heavy snowstorm last winter left countless people without a fixed place to live.

Because the common people could not afford green bricks, and the quality of the houses was poor.

Those who are a little richer use rammed earth, and those who are almost use thatched and wooden houses.

With red bricks, match them with cement.

Not to mention anything else, a small one-story house can be easily built.

Red bricks are fired from the red clay on the mountain, and there are quite a few of them in Dengzhou.

He has already begun to order people to carry out protective mining and excavation, and even a brick-burning factory has begun to be established.

When spring starts, at least 2000 people will have job opportunities because of this.

Digging, transporting, burning bricks.

There are also brick movers on the construction site!

Lin Xuan roughly explained, and Li Shimin's head was buzzing.

Green bricks are of good quality, but the cost is high and the output is low, so ordinary people cannot afford them.

Red brick is the exact opposite!

Chapter 284 What do we learn to do with such a scary thing?

"So, Qinglong King, what do you mean to say that these red bricks can not only be used to build roads, but also can be used to build houses that will not collapse for dozens or even hundreds of years?"

certainly!Even if it is hailstones, don't be afraid!

Li Shimin's face was shocked, his eyes were dull, and he held the rectangular red brick in both hands, his hands were trembling with excitement.
