In the early morning, the courtyard was lively.

Amid the chirping of the children, the women raised the coal stove to start a fire there.

Broken firewood, broken charcoal, rotten leaves......

There were all sorts of things that lit the fire, and for a time the courtyard was full of smoke and fire, and from time to time there was the sound of women coughing, but in spite of this, they still fanned the stove with small fans while they lit the fire.

In the choking coal mist, Chunhua went directly into the small kitchen made of wattles in the corner of the courtyard, and after a while, she came out with a kettle and shouted into the house.

"Dad, the hot water is ready, come out and wash your face."

When pouring hot water from the kettle into the basin, Chunhua deliberately glanced at the sisters-in-law in the yard, and heard the coughing sound of the sister-in-law of the Wang family, so she said.

"Sister-in-law of the Wang family, look at your choking, these tears are coming out, you are busy first, I will cook and ......"

After speaking, he shouted again.

"Dad, don't hurry up, don't let this water get cold for a while."

When the women in the courtyard heard this, their faces became complicated.

Well, before they lit the fire, the water was already boiling.

"Dexing, this is all April, and I boiled water to wash my face, and I saw the ...... who gave her to Dese"

"Sister-in-law Wang, look at what you said, the briquette stove used by people is different from ours, it is smoldering, the door is only opened when three coals are cooking, three coals can cook for a day, and the kettle can be heated into warm water when placed on it......"

"It's not, that's like us, we have to raise the fire every day, not to mention anything else, what kind of honeycomb briquette stove is used to save the match money a day, and I have to go out for three or four dollars, and I have to go out one or two a year."

Listening to what others said, the sister-in-law Wang, who was covered with soot, looked at the small kitchen where the smell of rice was already coming out, and said.

"As long as they have a coal stove at home, we can also buy it, and this old lady will go and buy one back, as if someone can't afford it, why don't you change the stove for a few dozen dollars, and the firewood money for ten days is enough......"

"That's it, it's just, it's still Sister-in-law Wang's idea, and I have changed it, but the firewood money saved is enough......"

The lively kung fu in the miscellaneous courtyard also shows the changes in the capital for a while, firewood, rice, oil and salt, originally nothing has changed, but this time it has been played by the coal shop in the capital, a humble honeycomb coal and briquette stove, to some extent changed the lives of the people in the capital, not to mention that it saves money, at least those women save the pain of smoke and fire for cooking.

Honeycomb coal and the new briquette stove are not very cost-effective to use, that is, to save the money for a firewood, but it is convenient for the public, which is only half a month's work, and tens of thousands of households inside and outside the capital have switched to honeycomb coal.

The coal shops unexpectedly found that the convenience of honeycomb coal further popularized the use of coal, resulting in an increase in coal consumption inside and outside the city, compared with usual, they sold more than one percent of the coal, the size of the coal shop is naturally a laughter, but, in addition to laughter, they can't help but be a little worried, worried that the coal plant can not supply coal, as for the coal factory is thinking about how to transport the coal from the coal kiln.

The changes in the market naturally spread to the Guogong Mansion and to Zhang Rong's ears, and it was at this time that Shi Yiwen was invited into the Guogong Mansion as a distinguished guest, of course, he was invited as a distinguished guest because he cured Zhang Weiliang's illness.

"Oh, I originally thought that Zhiyuan was good at doing business, but I never thought that there was still a wonderful hand to rejuvenate the ability, Liang'er's tuberculosis was originally said to be an incurable disease by many famous doctors, and today it can be cured, all thanks to Zhiyuan, this kindness, the old man inherited the ......"

From ancient times to the present, there have been great graces that say without thanks. This kind of favor cannot be repaid with money. I can only keep it in mind and report it another day.

Although you are a national prince, Zhang Rong talks and does things, but he is more like an ordinary outsider, in fact, if it weren't for knowing his identity, Shi Yiwen would have thought so.

"Guogong is polite, but it's just a coincidence."

Shi Yiwen didn't take credit for it, and even now he didn't think it was a big deal to save his life, after all, the Song family had already disappointed him.

The heart is separated from the belly, the grace of saving lives...... It may not necessarily be that the spring will return to save Zhang Weiliang, but it is just to bring the relationship between the two sides closer, nothing more.

Encouragement to report. It's human nature. But selfishness and ingratitude are also human nature.

"Thank you for your kindness."

Zhang Rong didn't say too much, if the great kindness was kept being said, it would seem false, and if he wanted to pay it back, he would definitely have a chance in the future. He didn't ask the other partner, and after chatting for a while, he said.

"Zhiyuan, a few days ago, the housekeeper in the house replaced the stove in the house with the briquette stove that specializes in burning honeycomb coal, after the coal stove was used in this house, it burned hundreds of catties of coal a day, but even so, it was better than using firewood, no way, there were many people in the house, and the day always had to be carefully calculated, but the old man heard that the coal in the coal shop was almost not available......"

Looking at Shi Yiwen with a smile, Zhang Rong said curiously.

"Earlier, you said that you were going to build roads to transport coal, why did you think that there would be a shortage of coal now?"

"Not to mention, in the past, ordinary people in the capital often used coal, because coal needs to be smoldered to raise the fire, but a liter of fire is full of firewood smoke in the yard, and there are many inconveniences in the smoke and fire, so in the courtyard of the deep house, firewood and charcoal are often used, which is more expensive, but the smoke goes with the chimney."

In fact, at the beginning, Shi Yiwen didn't know that the big families mainly burned firewood and coal, and it was only when the iron factory was pushing the honeycomb briquette machine that he knew about this, and he never thought that it was because of those wealthy families who switched to honeycomb coal that the originally sufficient coal suddenly became nervous.

"After the honeycomb coal can be used, there is no need to raise the fire all day long, everyone changes to burn coal, and the coal will naturally not be supplied, in fact, the coal of Mentougou is not not supplied, but can not be transported, because the transportation of mountains and mountains is inconvenient, if you want to transport the coal out, you must build a road, and the ordinary road is not good, once it is summer, the rain is more, the transportation will still be affected, so I want to build a railway."

As soon as Shi Yiwen's words fell, Zhang Yuangong was surprised.

"Railroad? What railway? Could it be that the iron paved road can't be done? ”

Compared with Zhang Yuangong's surprise, Zhang Rong seemed quite calm, just responded lightly, and then said.

"Railway, this sounds a little fresh, I have only heard of paving roads with stones and bricks in the past, what kind of road is this railway, please tell me about it."

For the surprise of people in this era of the railway, Shi Yiwen has long been surprised, after all, for the people of this era, the railway is really a fantasy, it is not easy to explain, they don't know what convenience the railway has.

How to explain it?

After thinking about it, the chopsticks in front of him made Shi Yiwen's eyes light up, so he picked up the chopsticks and put them on the table to explain.

"Actually? There's nothing new about this railway......"
