Chapter 410: Coal Briquettes as Fuel
With Shen Qingqian's words, Wu felt relieved, but she still had a question.
"We've tried to light a fire in the shed in the field these past two days, but the results aren't ideal. Sometimes the smoke is so thick that people can't get close. I came back late today just to see how to solve the problem."
Shen Qingqian slapped his head and said, "Look at me, I seem to have forgotten something important. I will draw a blueprint in a moment. You can give it to Brother Jiang tomorrow. Then ask Uncle Wu from the opposite yard to come and watch and add heat pipes to the ground."
Mrs. Wu was a little confused, so Shen Qingqian briefly explained the principle of heat conduction.
"So that's how it is. Fine then, we'll discuss it tomorrow."
The medicinal herb field was under the charge of military personnel, so everything went smoothly, but the small valley where Shen Qingqian and his group were was a wasteland, so they had to figure it out on their own.
The creative enthusiasm of the working people is endless. In a blink of an eye, a few days passed and Jiang Goudan and his team had already built the same heat conduction pipes in the small valley as those in the medicinal herb field.
The difference is that coal briquettes are used as fuel in the medicinal herb field, while firewood is burned in the small valley.
Ever since coal became available to the Hubei-Northern Army, Mr. Qin and his colleagues have been studying the use of coal.
The tools for making coal briquettes were still the ones Shen Qingqian had instructed Shen Xiao to draw, and the finished product was similar to modern coal briquettes.
Speaking of this, I have to mention in passing that the army now uses coal briquettes instead of firewood to cook.
Apart from the fact that it requires a stove, this thing is much more convenient to use than firewood.
Let’s get back to the present.
Another day passed quickly, and Shen Qingqian returned to Old Qin's yard from the medicinal herb field.
"Brother Sun, you go back first. I'll go there by myself." Shen Qingqian smiled and refused Xiao Sun's escort.
Shen Jun and the others wanted to send her off, but their current status did not allow them to move around casually, so Xiao Sun volunteered to accompany Shen Qingqian to Qin Lao's place every day.
"It's okay, it's just one more turn, it's still on the way." Xiao Sun waved his hand and smiled.
He had no bad intentions towards the Sixth Girl. He simply felt that she was a young girl who finished work very late every day, and he was worried that she would be unsafe on the road.
Over the past few days, everyone has been watching the medicinal herb seedlings pop up one after another in the fields, especially the ones that Sixth Miss reportedly used a secret recipe to plant. In less than five days, they've already grown over a foot tall!
Doctor Hu and the people in Jingrentang all found it incredible, not to mention the apprentices themselves, who could talk about their admiration for the Sixth Miss all day and all night.
Since he said so, Shen Qingqian naturally didn't say anything more. She quickened her pace and soon returned to Old Qin's place.
The old man hadn't come back yet, so Shen Qingqian went to the kitchen to prepare a midnight snack for him and boiled some hot water.
Just as she rolled out the noodles, she heard the voices of Old Qin and others in the yard.
Old Qin doesn't live alone in his yard. There are also two apprentices, Chen Jun and Deng Kai, who follow him and take care of his daily life.
Shen Qingqian pulled the bellows a few times, and the fire suddenly grew bigger. The water in the pot, which had been warm, soon boiled.
"Oh, it smells so good, teacher. Sixth Miss has made you another midnight snack." Deng Kai looked at the kitchen enviously and swallowed.
Chen Jun quickly went to pull him, "Let's go back to the room first."
Although he was also greedy, the sixth girl was doing it for the teacher. If the two of them approached, wouldn't it make things difficult for her?
"Brother Jun and Brother Kai, I also made a bowl of noodles for you. Hurry up and take it." Shen Qingqian walked out of the kitchen holding the bowl that Old Qin had made and said to them with a smile.
Qin Lao's tired expression disappeared, and he looked at Shen Qingqian with a scolding look, "Didn't I tell you not to make trouble at night?"
"Stop bothering me. You've been tired all day. Come inside and have some noodles." Shen Qingqian urged with a smile.
"I'm talking to you." Old Qin wanted to say a few more words, but his words were interrupted by a figure that suddenly fell from the sky.
"Sixth sister, come with me!"
Before Shen Qingqian could react, she was lifted into the air by someone!
