Li Shilang was younger and quickly adjusted himself, "This kid looks pretty good, haha!"
When Li Shilang saw that Jia Shangshu hadn't recovered, he continued to give instructions: "I invited Madam Tang San here today because I also want to ask about the farmer's fertilizer. There are still many things that I don't understand, and I need you to explain them to me." Ichiban.”
Shen Fei nodded, "Okay, no problem."
Zhu Baigong had never seen the late emperor. At most, they were curious about Shen Fei bringing the child here, and they were also curious about her waist stool straps.
Take a few more glances!
"Thank you, Mrs. Tang San."
"You're welcome, where do we start? It seems like..."
Shen Fei didn't finish her words because this was not a place for teaching.
At this time, Li Shilang continued to speak: "Tang Yuanwailang, I would like you to accompany Mrs. Ling here in the past few days, and study this thing called chemical fertilizer with the other workers."
Tang Zhiling was not worried that Shen Fei was here, so she nodded hurriedly, "Yes, I understand."
Li Shilang nodded, "Okay, all craftsmen, you can take Mrs. Tang San to your research room. If there is anything you still don't understand, the other craftsmen from the Ministry of Industry will be at your disposal."
Tang Zhiling and all the workers said, "Yes, Sir."
So Shen Fei took Xiao Fubao and left with Tang Zhiling.
At this time, Jia Shangshu was confused. He now had a big question.
What happened to Tang Guogong?
Does he know that there is a little emperor at home?
This thing is very strange, no one in this world looks like that for no reason.
And whose child this child is.
Everyone in the capital knew that Mr. Tang San married a widow, and the widow brought a small oil bottle with her.
Now that this little kid looks so much like the late emperor, who does this child belong to? Calculating the time, it can’t be the late emperor’s. Could it be that he is the son of the current emperor or some prince?
What's the trick here?
Jia Shangshu started a conspiracy theory.
Thinking of the military power in the hands of Duke Tang, Jia Shangshu himself broke into a cold sweat.
"Qiongfang, let's go quickly and enter the palace immediately to meet His Majesty."
Qiongfang is the given name of Shilang Li Tai. In private, Shangshu Jia still calls him Shilang Li this way.
"Sir, without further ado, let's go!"
Not only Jia Shangshu was thinking about it, but Li Shilang himself was also thinking about the big dramas.
He is also extremely curious now.
When Jia Shangshu stood up, his head felt dizzy again and his body swayed.
Li Shilang walked quickly to Jia Shangshu's side and supported him, "Sir, there is no need to worry. The matter may not be as serious as we think. Otherwise, how could Duke Tang allow them to leave the house so freely."
"Qiongfang, you are right. Let's go. We are really old and can't hide anything anymore."
Li Shilang cursed in his heart, anyone who found out about this would have to complain.
Jia Shangshu and Li Shilang hurriedly left in the car.
At this time, Shen Fei had arrived at the research room of the Ministry of Industry. Xiao Fubao had been untied from her body by Shen Fei, and Tang Zhiling was holding him.
Little Fubao is young and not noisy, but looks around curiously.
Shen Fei took the chemical raw materials and explained them to the craftsmen from the Ministry of Industry.
She first introduced these raw materials to everyone, including the acidity and alkalinity of some relatively common substances, such as plant ash, saltpeter, quicklime, limestone, rust, caustic soda and other substances.
She also did a small chemistry experiment in front of everyone, which was a small case of acid-base neutralization.
An experiment was conducted with rusty ironware. Everyone was surprised to see that the rusty iron quickly became smooth.
Just this is an eye-opener for everyone, and those with quick minds have already been inspired.
Also because of the applause of the crowd, more craftsmen from the Ministry of Industry were attracted to come and watch, and they were no longer afraid of wasting time.
After Shen Fei's introduction, she started to get into today's topic, how to make fertilizer.
The chemical fertilizers in Shen Fei's space laboratory are limited and impossible to obtain, so her recipe is a combination of farmyard manure and chemical raw materials.
Tang Zhiling stood aside and watched Shen Fei's eloquent speech, feeling that her whole body seemed to be glowing.
Shen Fei didn't notice the way Tang Zhiling looked at her. Like a little teacher, she said calmly and generously: "Let's take a look at the third fertilizer I mentioned, which is ammonium sulfate fertilizer.
This is a very easy-to-use fertilizer, and it is very simple to make. Not only does it have a wide range of raw materials, it saves time and effort, but it is also very efficient.
The method is to use about 50 kilograms of human feces and urine, add 20 kilograms of water, and then add 5 kilograms of plaster of paris powder. After stirring evenly, seal it and leave it for about 10 days. "
At this time, someone asked: "Mrs. Tang San, this is not much different from ordinary excrement retting, except for the gypsum powder."
Shen Fei snapped her fingers at this time and said, "This uncle has got the point right. If the rest of us have questions, we should ask them in time, so that I know whether you understand or not."
The old man who asked the question was embarrassed to be praised in public, so he scratched his head.
At this time, someone asked, "Gypsum of Paris powder, I remember it is a medicinal material!"
"Yes, plaster of paris powder is made from gypsum ore that has been burned, purified, and ground. It is a mineral herbal medicine known for its effects of clearing heat, detoxifying, cooling blood, and stopping bleeding."
"Gypsum of paris powder is also very useful when used in retting. Adding gypsum of paris powder can speed up the decomposition of feces and turn it into fertilizer."
"...."
Shen Fei was here today and talked about many methods of retting.
"Okay, that's it for today. You should experiment according to the method I told you. It's still some time before spring farming starts, so don't be in a hurry."
Everyone nodded in agreement. In addition to being helpful to their own jobs, the reason why they listened so carefully was that they also had fields at home. Now they know better fertilizers, fertilizers that can make farmers more productive. Who knows? How can I not be moved?
After everyone left, Shen Feicai came to Tang Zhiling and saw that Xiao Fubao had fallen asleep, "Tang Zhiling, let's go home!"
Tang Zhiling looked at Shen Fei with soft eyes, "Okay, let's go home."
Shen Fei and Shen Fei were affectionate. In the palace, the emperor was really shocked, "Jia Shangshu, who did you say you saw?"
