I'm a marquis in Datang

The two women responded one by one.

Du Qi didn't doubt the ability of the two girls, because the two girls had been playing for many years and were very capable.But the two women have the limitations of this era, even if they have a good vision, they can't get out of the rut.

Du Qi wants to let the two daughters have a more forward-looking vision.

gain deeper insight.

Li Yanyun and Qianxue listened to Du Qi's words, and they also had doubts in their hearts, so they immediately raised themselves, and Du Qi was responsible for solving them.After walking around in the backyard, the three went straight back to the room to rest.

Chapter 739

Toss about

The weather in late November is getting colder, and there is even heavy snow falling.The entire inside and outside of Yiwu County was shrouded in a piece of silver, turning into a vast white world.

Up to now, many things have stopped, and the people are idle.

Du Qi didn't wear thick clothes, but loose clothes.

He is reading in the study.

It's just that when Du Qi was reading, the attendants entered several times and added charcoal to the brazier to dispel the chill.Although there are anthracite stones mined today, the taste of anthracite is not as good as such charcoal.In Du Qi's palace, the servants used coal, while Du Qi himself used charcoal.

When Du Qi was bored while reading, his eyes fell on the burning charcoal.

Charcoal burns, and there is no smoke.

On the contrary, there is a trace of fragrance coming out of the charcoal, which makes the room smell very good.Du Qi's thoughts suddenly flew to the coal that is being sold now.

Coal has been widely sold, and many people can afford it, as it is not expensive after all.Plus the people of Illinois today

, because Du Qi exempted many taxes and carried out countless fortifications, the people's life is generally good, and there is no shortage of money to buy some coal.After all, coal can be used for heating and boiling water, and has many uses, and many people are buying it.

It's a big industry today.

What Du Qi thought of was the honeycomb briquettes of later generations.At a certain stage in later generations, briquettes are necessary for every household.It was not until coal gas and natural gas began to be popularized on a large scale that briquettes gradually withdrew from the mainstream.

Even so, honeycomb still has a place, after all, it can be used in many places.

If Du Qi wants to make briquettes, he needs a machine for making briquettes.In the current environment, there is no mechanization at all, and now more is done by hand, so it is definitely impossible to make complex briquette-making machines.

What can be produced can only be the simplest manual twelve-hole briquette mold.

The production of honeycomb briquettes by such molds is entirely manual. Although the speed is slow, it is sufficient to meet the current needs on the current basis. Moreover, with such productivity, many workers are needed to work, and it can also allow people to work to make money.

After searching in Du Qi's mind, he found a mold for making twelve-hole briquettes, and began to copy and draw sketches.

This mold is not complicated.

After the sketch drawn by Du Qi was corrected several times, the condition of each part of the mold was marked.When it comes to parts, the mold itself is actually the simplest, and there are not many labels.In a short period of time, Du Qi has completed all of them.Wait for the ink to dry

After drying up, Du Qi put away the drawing and said, "Liu Jian!"

"exist!"

Liu Jian entered the room to answer.

Du Qi said, "Get ready, let's go to the University of Science and Technology."

"Yes!"

Liu Jian answered immediately.

When it comes to making briquette molds, the craftsmen in Du Qi's mansion can't do it, so they have to rely on the cooperation of many craftsmen from the Manufacturing Academy.Du Qi went to the University of Science and Technology this time, just to take a look at the situation inside the school.

It is snowing heavily outside now, but the main streets in the city are all cleaned by someone.Moreover, the main official roads inside and outside Yiwu County, Yizhou are all poured with concrete. The roads are easy to clean and easy to pass, and the speed of driving is very fast.

Horse-drawn carriages drive on it, and it is easy to pass.

Sitting in the carriage, Du Qi looked at the current Yiwu County with a smile on his face.Because today's Yiwu County is quite clean, adjustments have been made everywhere, and the overall look is very good.

Du Qi raised the curtains of the carriage and looked out. Except for the concrete official road, it was still white.

In the sky, there is heavy snow falling.

The ground is a concrete road, and the snow melts quickly after falling on the ground.And even if there is some snow, the roads in the city need to be cleaned every once in a while, so there is no need to worry about snow blocking the roads.

"Drink! Ha!"

At this moment, Du Qi suddenly heard shouts.Curious in his heart, he looked through the curtains of the carriage and saw about a hundred people on the road ahead, hurrying neatly.

The clothes of these hundreds of people are very ordinary, and some people's clothes are even relatively thin.Moreover, this group of people are all gray-haired, and at least they are 50 to [-] years old.

In their hands, each one is carrying a broom.

This scene surprised Du Qi a little.

What kind of battle is this?

In particular, a group of elderly people carried brooms and walked neatly in the cold weather, and some of them were not dressed too thickly.Heavy snow was flying in the sky, and a cold wind was blowing, but a group of old people were on their way.

Du Qi said: "Stop!"

Hearing this, the groom who drove the carriage tightened the reins immediately, the carriage stopped, and stopped moving forward.

Liu Jian said: "Young master, what's the matter?"

He was sitting on the shaft.

As for Moredo, he rode along with him on the horse, and did not sit on the shaft of the chariot.

Du Qidao: "Liu Jian, go and ask, what are these elderly people doing when they are walking neatly? It's very strange for a group of people to walk on the official road in cold weather. Remember, don't reveal your identity, get to know first."

"Yes!"

Liu Jian got the order and immediately jumped out of the carriage.

He hurried forward.

Liu Jian didn't ask the old man, but went straight to the front and saw the leader.The leader was an old man, about fifty years old, with a rather lean body and slightly thicker clothes.

Liu Jian came forward to strike up a conversation to understand the situation, but fortunately, the leader was kind and said with a smile: "We are all sweepers, and they are in charge of the streets in the city. Because the higher-ups have arranged, we have to rectify discipline. The higher-ups require that we You must have the spirit of a soldier and the discipline of a soldier, so let us practice walking in the city together in the cold weather."

Liu Jian was stunned when he heard it.

He really couldn't understand why street sweepers still need to practice, rectify discipline, and have the spirit of a soldier.

God.
