With Shen Qingqian's words, Wu felt at ease, but she still had a problem.
"We have tried to light a fire in the shed in our field for the past two days, but the effect is not ideal. Sometimes the smoke is so thick that no one can get close. I came back late today just to see how to solve it."
Shen Qingqian slapped his head, "Look at me, just say that you seem to have forgotten something important. I will draw a drawing in a while. You can show it to Brother Jiang tomorrow, and then ask Uncle Wu from the opposite yard to look at it and add heat pipes to the ground." .”
Wu was a little confused, and Shen Qingqian briefly explained the principle of heat conduction.
"So that's it. Let's do it. We'll discuss it here tomorrow."
There were people from the military in charge of the medicinal field, so everything went smoothly, but Shen Qingqian and the others in the small valley were in wasteland, and they had to deal with it on their own.
The creative enthusiasm of the working people is endless. A few days passed in the blink of an eye. Jiang Goudan and the others had already built the same heat-conducting pipes in the small valley as they did in the medicinal field.
The difference is that briquettes are used as fuel here in the medicinal field, while firewood is used in the small valley.
Ever since coal passed through the Northern Hubei Army, Mr. Qin and the others have been studying the use of coal.
The tools for making briquettes are still the ones Shen Qingqian prompted Shen Xiao to draw, and the finished product is similar to modern briquettes.
At this point, I have to mention in passing that the military now uses briquettes for cooking instead of firewood.
In addition to being equipped with a stove, this thing is really much easier to use than firewood.
Back to the present.
The day passed quickly, and Shen Qingqian returned to Mr. Qin's yard from the medicinal field.
"Brother Sun, please go back first. I'll go there myself." Shen Qing 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 wander around casually, so Xiao Sun volunteered to accompany Shen Qingqian to Qin Lao's house every day.
"It's okay, it's just an extra turn, so it's still a smooth road." Xiao Sun waved his hand and smiled.
He didn't have any bad intentions towards the sixth girl, he just felt that she was from a young girl's family and finished work very late every day, so he was afraid that she would be unsafe on the road.
In the past few days, everyone has been watching the medicinal seedlings emerge one after another in the field, especially the place where Miss Six was said to have used a secret recipe. In less than five days, they have grown more than a foot tall!
Doctor Hu and everyone in Jing Rentang found it incredible, not to mention their apprentices, that they could talk about their admiration for Miss Six all day and all night.
He had already said this, so Shen Qingqian naturally couldn't say any more, so she quickened her pace and returned to Mr. Qin's place not long after.
Before the old man came back, Shen Qingqian went to the kitchen to prepare supper for him, and also boiled the hot water.
As soon as she rolled out the noodles, she heard the voices of Mr. Qin and others in the yard.
Mr. Qin is not the only one living in this courtyard, but there are also two apprentices who are with him and responsible for his daily life, Chen Jun and Deng Kai.
Shen Qingqian pulled the bellows a few times, and the fire suddenly became stronger. The water in the pot, which had been warm, quickly boiled.
"Ah, it smells so good, teacher. Miss Six has made you another supper." Deng Kai looked enviously in the direction of the kitchen and swallowed his saliva.
Chen Jun quickly went to pull him, "Let's go back to the room first."
Although he was also greedy, the sixth girl made it for the teacher. If they got together, wouldn't it make things difficult for them?
"Brother Jun and Brother Kai, I also made a bowl of noodles for you. Go and serve it quickly." Shen Qingqian walked out of the kitchen with Mr. Qin's bowl and smiled at the people.
Mr. Qin's tired expression was gone, and he looked at Shen Qingqian angrily, "Didn't I tell you, girl, not to mess around at night?"
"Don't bother, you've been tired for a long day, hurry up and eat some noodles." Shen Qingqian urged with a smile.
"I said you..." Mr. Qin originally wanted to say a few more words, but his words were interrupted by a figure suddenly falling from the sky.
"Sixth sister, come with me!"
Before Shen Qingqian could react, he was lifted up into the air by someone!
