Small courtyard.
Su Yang is concentrating on drawing.
Since Bao Zhao came to visit that day, he has never visited again.
In fact, Su Yang also knew in his heart that the old gentleman was angry with him.
After all, Bao Zhao is a loyal and patriotic loyal minister. You can be a madman and accuse the king of his faults, but you cannot persuade a pure and good minister to betray his monarch. This is tantamount to humiliating him.
Therefore, Bao Zhao rarely became angry with Su Yang and never came again.
Although Su Yang felt a little guilty about this, he did not regret his choice.
Because he was saving Bao Zhao, a pure and good minister.
Following a master like Emperor Jianwen Zhu Yunwen will not end well!
Even if the Yan King Zhu Di fails to rebel, the Ming Dynasty has entered the Jianwen era when the scholarly court was in charge. With the old man's upright temper and temperament, sooner or later he will not be tolerated by the court!
So, it’s better to get out as soon as possible.
As for Xiaowan's family, Su Yang has not seen them for several days.
It seems that the imperial envoys arrived in Peiping, and the Yan Palace had to deal with it with all its strength!
But this is a good thing, after all, no one will disturb their peaceful life as a couple.
Su Yang is busy drawing drawings now, and in his spare time, he teaches his young wife to learn arithmetic. If she gets bored, they go out to the market together. They live a peaceful and happy life.
The only difficulty lies in drawing the drawings.
Although there is a brush at home, Su Yang can write with the brush, but it is a bit difficult for him to draw with the brush.
The lines were too thick and the ink was too thick. Su Yang tried several times but finally gave up.
"Ms. sir, what are you thinking about?"
"I'm thinking of making a pen."
"Don't you have a writing brush at home?"
The little girl was stunned for a moment, not quite understanding.
"The brush is too thick for drawing."
"Well...I've seen those painters before. They all use special fine brushes to draw, as black as charcoal..."
Hearing this, Su Yang's eyes suddenly lit up, he slapped his thigh suddenly, hugged the little girl and kissed her, and then ran to the kitchen in a hurry.
Zhu Wanqiu was confused by Su Yang's "surprise attack" and froze on the spot, then her little face turned red with shame.
"Oh...it's really...in broad daylight...shameless!"
The little girl complained a few words, then followed curiously.
Su Yang took out a few red coals from the stove with a shovel, and then brought a ladle of cold water.
Wow!
Suddenly a cloud of white air burst out, dust flew, and a mushroom cloud rose. The little girl stuck out her tongue in fear, looking extremely cute.
After the charcoal cooled completely, Su Yang reached out and picked it up.
Seeing his daughter-in-law standing there with curiosity on her face, Su Yang suddenly teased and said with a smile: "Xiao Wan, go and wash up quickly, she has a face like a cat!"
The little girl was stunned, covered her face in shame, turned around and ran away, Su Yang's laughter came from behind.
In front of the basin, peeking through the fingers, you can see that the delicate face is covered with dust and charcoal powder, black and gray, he looks like a little beggar.
"It's so ugly, it's so ugly! You've made your husband laugh again!" The girl quickly held the water and washed away the dust. Not worried, she ran to the mirror and looked left and right, fearing that there were some flaws.
Just when Zhu Wanqiu was feeling pity for herself, Su Yang had already used charcoal to draw a three-dimensional diagram. It was either a mysterious thing or the most common stove in later generations.
After washing, the little girl ran over happily, and her eyes widened when she saw the painting.
Although she is not good at the art of painting, this painting is too realistic, and it immediately attracted her attention!
"Ms. sir, this... this thing is a stove, right?"
"Yes!"
Zhu Wanqiu frowned immediately and couldn't help but said: "Although the iron stove is smaller than the stove, it is also more expensive. I'm afraid no one will buy it."
After spending such a long time with Su Yang, the little girl also learned some common sense in life.
Su Yang smiled and nodded, "But it is more convenient than a stove. As long as the charcoal fire is put in the chamber, it can not only keep warm, but also barbecue and cook."
"Besides, this stove is not for sale. The money at home is enough for us to live on."
"Winter is coming soon. You should go out as little as possible in the future. This stove is for keeping you warm. With this stove, our little Wan can have a warm winter!"
Hearing Su Yang's words, the little girl's eyes instantly turned red.
She thought Su Yang was just trying to make money again, but who would have thought that Su Yang was doing it for herself.
Recalling that Su Yang had been busy drawing drawings these past few days, the little girl's feelings became stronger and she hid directly in Su Yang's arms.
"Ms. sir, you are so kind!"
"Silly girl, what are you talking about?"
Su Yang smiled and comforted his wife, and then started drawing again with charcoal.
The stove is available, but the problem of charcoal fire must also be solved.
You must know that in this Ming Dynasty, charcoal was also a very expensive thing.
In the absence of air conditioning and heating, the people of the Ming Dynasty had only a handful of heating fuels, including charcoal, coal and firewood.
Among the three, charcoal heating has the best experience, but it is extremely expensive. Generally, only princes, nobles, dignitaries, and wealthy businessmen can afford it!
Because making charcoal is also a very hard physical job, the mountain people have almost no time to rest from morning to night, from chopping firewood to cutting wood into sections, then to splitting firewood, building a kiln, and finally burning it into charcoal. It takes ten days.
Moreover, the firewood collected is generally hardwood, so that it can be burned to produce high-quality products that are resistant to burning and smoke-free.
For example, the imperial charcoal used by the Ming Dynasty royal family for winter is "Hongluo charcoal", which is made from hardwoods in the mountains in Yizhou. Each charcoal is about a foot long and varies from two to three inches in diameter. It is warm and durable, gray but not explosive. There is still a slight aroma when burning!
However, the output of this high-quality charcoal is rare and expensive. Even the royal family cannot use it for a long time, let alone the common people!
In this era, most people want to keep warm, rich people burn charcoal, while the poor and humble can only burn firewood.
Although charcoal is time-consuming and labor-intensive to burn, it is very popular among wealthy households because it burns more fully and does not produce too much smoke.
Well, after all, they are people with status and status, which fits their arty style.
But firewood is different. Once it is burned, it will be filled with smoke immediately, and it requires poor people to go out of the city to harvest it. It seems cheap, but in fact it takes a lot of effort.
As for coal, no one dares to use it in this era.
Ordinary coal will produce a lot of smoke, and because there are too many impurities and the sulfur content is too high, it is equivalent to poisonous smoke when burned.
In later generations, the briquettes and briquettes commonly used by people actually needed to be refined, which was the step of "coal washing". However, in this era, the process of washing coal was too difficult and almost unfeasible.
However, anthracite is different. Anthracite has extremely low sulfur content. The most important thing is that it burns colorless and smokeless, and burns for a long time. It is an excellent fuel to keep out the cold.
If Su Yang remembers correctly, there is an anthracite coal production area in Peiping, located in the upper reaches of the Yongding River in the west of Beijing and on the east side of the Dahan Mountains, in the Xishan area outside Peiping City. The annual output of high-quality anthracite coal is millions of tons!
It seems that if you want to produce this anthracite coal, you have to bring in dudes like Guo You with you.
If the plan goes well, anthracite coal can enter the market at a reasonable price, saving some people in Beiping Prefecture from freezing to death in this cold winter!
After all, after coming to Ming Dynasty, Su Yang still wanted to do something for the people if he had the ability.
At least, we can’t just watch them starve to death and freeze to death!
