I'm a marquis in Datang

in the library.

Du Qi is writing a book, and the memory of "Water Margin" is extremely clear in his mind.

For Du Qi, the matter of excerpts is too simple, all he needs to do is keep transcribing.Of course, even if there is a part that needs attention, it is only a slight modification and will not have any impact.

When Du Qi was busy reading, it was Liu Jian who entered.

Liu Jian bowed and said, "My lord."

Du Qi asked, "What's the matter?"

Liu Jian replied: "The craftsman in our house came to report the news, saying that he had found a novelty, and wanted to invite you to take a look to see if it is useful."

The craftsmen of the Du family are all in the mansion.

Especially after making movable type printing and improving Quyuanli, Du Qi put forward new requirements and rewards for the craftsmen of the Du family.As long as there are any new inventions in the house, if they have practical value, they can be rewarded, so from time to time, craftsmen will come up with new things.

Just a lot of items, not much use.

Du Qi smiled and said: "Let's go, take a look, and figure out what

good stuff. "

"Yes!"

Liu Jian responded immediately.

Du Qi and Liu Jian went to the workshop in the mansion.

When he came to the workshop, many craftsmen inside stopped to salute Du Qi.Today's Du Qi is a veritable God of Wealth, and everyone in the house relies on Du Qi for life.

In particular, craftsmen researching new items are all rewarded by Du Qi.The Du family didn't have this rule, it was Du Qi who decided to reward new items with practicality.

Not long after, Du Qi came to the open area of ​​the craftsman's workshop area.

And the person who developed the new item this time also greeted him.This person's name is Yuan Kewang, and he is in his early sixties.

Quite old.

The fingers of his hands were extremely rough, and even a little dry and cracked due to the cold weather.His back was stooped, his stubble was messy, and one of his cheeks was a little bloody due to the frequent wind blowing.

This is often caused by strong winds.

When Yuan Kewang saw Du Qi, with a bright smile on his old face, he saluted and said, "My lord, you are here."

There is hope in his eyes.

Because he thinks his discovery is valuable.

It's just that these old brothers who work together don't agree and think it's worthless.

He wants to prove himself.

Also want to make money.

Du Qidao: "Master Yuan, what did you invent?"

Yuan Kewang immediately took Du Qi, and walked a certain distance, and saw Yuan Kewang squatting down, looking at a bulging dirt bag on the ground, Yuan Kewang squatted down, hit it with a hammer, and said: "My lord, look, This is my invention. Inside the soil bag, it is ordinary soil compacted. Outside, I used a layer of mud. After this layer of mud dries up, it is extremely hard. Even if it is lightly beaten with a hammer, it will not be destroyed. This Mud is my invention."

Du Qi looked at the dried up mud, but a smile flashed across his eyes.

Isn't this concrete made of cement?

Can solidify!

At the same time, a certain hardness is formed.

Du Qi looked at Yuan Kewang and said, "How did you find out about this situation?"

Yuan Kewang said: "My lord, it's actually a coincidence. At first, I mixed clay and water, which was too thin. There was lime next to it. By coincidence, I mixed some lime to make it thicker. .Unexpectedly, in the end, the formation of

had such an effect. "

"This is not my second experiment, I have tried it several times."

"Once the mud mixed together is dry and hardened, it will be extremely strong. I think this kind of discovery can be useful, so I invited you to come and comment."

Yuan Ke looked at Du Qi eagerly.

Everyone around looked over in unison.

He has a smile on his face.

In ancient houses, the reason why wooden houses are the main ones, and some are earth walls made of rammed earth instead of masonry structures is very simple. In ancient times, there was no cement, which could not make the stones truly stable.

With cement it is different.

With the appearance of cement, buildings will change, and gradually become all brick and tile structures.In particular, the emergence of cement will cause changes in the road, which can lead to changes.

As the saying goes, if you want to get rich, build roads first, this principle is true.

All eyes were on Du Qi.

Du Qi coughed twice, and said, "I won't say much about the situation of the mud. In short, I think it's excellent. At the same time, I will give Yuan Kewang the highest level of reward, a set of houses in Chang'an City , and a reward of five hundred coins."

"Thank you, son!"

When Yuan Kewang heard this, he immediately became excited.

It's done.

Such the highest level of reward is not available in the entire craftsman workshop.

Yuan Kewang is the first one.

The rest of the people had inventions and got Du Qi's approval, and they got some other rewards.

"Young master, I am not convinced."

At this moment, someone among the craftsmen spoke.

His name is Diao Peng.

In his early forties, he is relatively young and vigorous among craftsmen.He is mainly responsible for smelting pig iron.Diao Peng also received awards, mainly because he increased the temperature of smelting.

However, the effect of Diao Peng's improvement is not particularly obvious.So Diao Peng received limited rewards, but he felt that Yuan Kewang's invention was nothing new, so he was not convinced.

Du Qidao: "I know you, my son. Your name is Diao Peng. Tell me, what do you think?"
