Throughout the night, Tang Haoran has been plagued by all kinds of thoughts, on the one hand, the time is getting tighter and tighter, and on the other hand, he is worried about what should be taught in tomorrow's class, and finally he thought of writing a few articles to make a name for himself, so he spent the whole night sorting out the materials he had read in his mind and wrote "Tessie's Vertical and Horizontal Technique: Prussia", which described the various diplomatic strategies implemented in the process of Prussia's rise in more detailed words.

Tang Haoran didn't know what this article would bring to himself, but he knew that compared with those "masters" who were proficient in "Zhihu Zeye" in China, he was more "proficient in the West", which was his only strength.

Now "proficient in the West" may be his only advantage.

After Tang Haoran, who stayed in front of the desk all night, finished writing "Taixi Vertical and Horizontal Technique", the sky was already white, and the air could even hear the unique pigeon whistle of old Beijing, listening to the pigeon whistle that swept across the sky, the corners of Tang Haoran's lips raised slightly, today, he will really get involved in the officialdom of the late Qing Dynasty, just like Ding Yunliang said, Tongwenguan is also officialdom, maybe he doesn't have any good impression of Ding Yunliang, but Tang Haoran knows that what he said is implementation, just like Chinese universities a hundred years later, it is also officialdom, There are not a few officials who have learned to do things.

For me, the Tongbunkan is just a stepping stone! Become a stepping stone to a great cause,

In the emotion, a violent coughing sound made Tang Haoran stunned, it was Yun'er coughing, what's wrong? Because of the pasting of window paper, when Tang Haoran walked out of the door and came to the yard, he saw that the kitchen door was already covered with a cloud of smoke, could it be a fire?

"Yun'er!"

Walking quickly to the kitchen door, Tang Haoran choked on the smoke and coughed a few times, and through the smoke, he could see that Yun'er was by the stove, as if he was leading the stove.

"Less, less...... Cough...... Young Master, you ...... Ahem, get out of here, smoke ...... Choke ......"

Yun'er's cough from time to time made Tang Haoran hurriedly pull her out of the kitchen, and a few gray stains could be seen on her white greasy face, and her bright eyes were even more bloodshot.

"Less, young master, I'm sorry, it's all my fault, the firewood for the stove was a little wet this time!"

Yun'er hurriedly explained that this firewood was bought by Young Master Tan's servant, who would have thought that it would be too tidal, and when the stove was lit, there would naturally be a lot of smoke and choking.

Seeing that the choked tears came out of Yun'er, a fifteen or sixteen-year-old girl like Yun'er in her own era who was in the flowering season was being favored by her parents, and she was also an immortal-level beauty in the future with her appearance, where she needed to suffer from this crime, Tang Haoran said as soon as she took the firewood from her hand.

"Don't do it, I'll raise the fire, look at you"

"Young, young master, how can this work, this ...... This smoke is gone......"

When Yun'er heard this, she immediately became anxious, and there was a girl ring to let the master go to the fire.

"I'll raise the fire first, wait for the fire to rise later, and then burn some tea!"

Tang Haoran blocked Yun'er and said with a straight face.

"Let you rest, you wait, I'll raise the fire, and you'll sit down and make tea in a while."

Seeing that the young master was annoyed, Yun'er still dared to insist, so she had to look timidly at the young master's clumsy stove, which would make her regret it, why not let people set up a stove in the kitchen, otherwise, there would be a stove there, but she secretly rejoiced in her heart while regretting it.

Tan Sitong, who had just gotten up and still had a headache with a hangover, smiled slightly when he saw this scene, living in Tang's house, he naturally saw that Tang Haoran treated this little girl differently, that there was someone who left someone else's house and wanted to leave someone else's house, Yun'er's girl ring did have a bit of a look, but her eyes were too big, just like a foreigner.

If it weren't for the relationship between living in the Tang family, he might even misunderstand that this Yahuan was his bed-warming Yahuan, but now it is not like that, but if it is not, how can he help Yahuan do things? Maybe Tang Haoran treats people differently.

Tan Sitong, who was not interested in these things, sat on the bench and watched Tang Haoran, who had never worked before, lighting the stove in the kitchen.

A handful of firewood stuffed into the hearth, after the firewood burned, Tang Haoran took the wrought iron stove tongs to pick up the briquettes, the so-called briquettes are definitely the "balls" in the wooden box of dozens of fist-sized briquettes, although the stove has not been led in the past, but these days looking at Yun'er leading the stove, naturally know how to lead it, after the fire is prosperous, Tang Haoran threw the briquettes into the hearth, picked a few times, picked the fire Wang, and then threw two pieces of firewood.

Because the firewood was a little wet, the whole kitchen was smoky and burning again for a while.

"This is a fire all day long, can it not be troublesome?"

Looking at the briquettes in the box in the corner, Tang Haoran, who choked on two puffs of cigarettes, couldn't help but complain when he walked out of the kitchen.

"Less, young master, this capital is like this, every household is burning briquettes, unlike Wuchang, where there is a lot of firewood and it is cheap!"

The young master's complaint made Yun'er hurriedly explain, he knew that he should really set up a stove, and Chai Gui was a matter of a few pennies.

Tang Haoran directly reached out and picked up a briquette, the fist-sized briquette seemed to be made of pulverized coal, and the briquettes of later generations, well, honeycomb coal is completely different, this is definitely a "ball", a solid "briquette", at least the honeycomb coal does not need to be used every day, three briquettes are enough for one day.

Tang Haoran, who was holding the briquette, looked at it for a long time, and estimated that it weighed almost a pound before asking again.

"How many meals do we need for this thing at a time?"

"Even boiling water for cooking, it takes seven or eight briquettes a day!"

Glancing at it, Tan Sitong said casually beside him.

"There are few people in our house, if we put it aside, even if there are only five or six people, it will cost twelve or thirteen briquettes a day,"

“……”

Tang Haoran was speechless for a moment, fifteen or sixteen catties of coal a day? If you switch to honeycomb coal, you can save about half of the coal.

"Burn this in the capital?"

"From the beginning of the dynasty, the common people and the palace burned coal, and as for firewood, it was used to start the fire! The briquettes are led in the morning, not to mention the fire that can be stuffed for a day, but also warm hot water, which is convenient to use, if someone comes, open the door of the stove but a pot of tea, you can boil a pot of boiling water, if you use the stove, it is not so convenient. ”

This is the truth, if you feel the most inconvenient in this era, the first one is to drink tea, unless it is a teahouse, a restaurant at home there is no ready-made boiling water, large families will use a charcoal stove, get a copper kettle that can only boil a pot of water to boil tea, with the use of the small family, but only when cooking, by the way boil some boiling water, put in a cold kettle.

"Brother Fusheng, do you mean that this coal stove is lit every morning and then smoldered for a day?"

But no, no wonder I usually haven't seen Yun'er raise fire, and I think that this burns coal, saving it like in Wuchang, burning firewood all day long, and getting it for a long time, which is not necessarily much easier than burning firewood.

Staring at the briquettes in your hands, briquettes, honeycomb coals...... Tang Haoran thought about these two words repeatedly in his mind, if he made honeycomb coal by himself, wouldn't it save Yun'er the trouble of raising the fire every day?

Not only can Yun'er no longer suffer the sin of smoke and fire, but he can even earn a sum of silver.

Thinking of silver, Tang Haoran's eyes lit up, just like Song Yuxin said, if Jingguan wants to release places, one is to rely on connections, and the other is to rely on silver, but in the final analysis, silver is needed, and with silver, there is everything. As for the 50,000 taels sent by Sang Zhiping when he left Wuchang, it seems to be a lot, but if he is an official, it is not a star or two points.

At this time, Tan Sitong walked over, looked at Tang Haoran who seemed to be thoughtful, and asked.

"Ziran, what are you thinking?"

"How do you make this briquette?"

"The dough uses coal to infiltrate soil and water, the dough forms a ball, and then collects the water and puts it in an iron heavy sieve, and the craftsmen in the coal shop keep shaking the big iron sieve, and the coal will naturally become a ball."

After many years of travel, Tan Sitong can be regarded as well-informed, and he has also seen how the apprentices in the coal industry make briquettes, but that is because of curiosity, curiosity about why they make briquettes so round.

It seems that this briquette is similar to the briquette of later generations, looking up at Tan Sitong, Tang Haoran asked,

"Is there a blacksmith shop near us, I want the blacksmith to get me something."

"Hit something, what?"

"Young Master Tang, there is a blacksmith shop at the entrance of the alley to the west of us!"

Tan Sitong's servant said on the side, Tang Haoran listened, then walked into the house and picked up the pencil bought in the Hankou concession, first recalled the structure of the briquette machine, he was no stranger to the briquette machine, until he was in middle school, every winter, his father's agricultural research institute will be divided into coal according to the head, cadres 800 catties, workers 500 catties of coal, every season, the agricultural research institute is full of briquettes "battlefield", basically every household has a briquette machine, sometimes Tang Haoran himself will be when his father feels tired, Hit dozens of briquettes or help wash the briquette machine.

But it is a thick round iron bucket, there are four or five rows of round steel bars, and there is a gasket, the structure can be said to be simple, but just a moment of effort, Tang Haoran drew a good briquette machine, as for the briquette furnace, Tang Haoran is not worried, when the furnace was bought, he saw that the furnace was burned out of two layers of pottery, the outside of the hoop iron sheet, the furnace is also round, in addition to the furnace mouth is larger, the furnace is shallow, and the briquette furnace of later generations is about the same, a little transformation can be used directly.

After drawing the drawings, Tang Haoran walked to the kitchen, took a wooden stick and compared the size of the hearth, and then wrote it down on a piece of paper.

"Just follow this size and appearance for the blacksmith to type."

After speaking, he took out two silver dollars from his body.

"These are two silver dollars, not enough for you to take it with Yun'er."

"Ziran, this is ......"

Looking at the things drawn on the paper, Tan Sitong asked with some puzzlement, but Tang Haoran looked at Yun'er who still had cigarette ash on his face and said with a smile.

"Self-cultivation Qi family rules the country and the world, if you don't cure the family first, what else do you talk about governing the country and leveling the world, with this thing, Yun'er will no longer have to get up early every morning to fire the stove in the future!"

But no, since I have a hundred years of insight beyond this era, why don't I first transform the environment around me and improve the quality of life, what else can I talk about doing big things! What's more, this can still earn money.
