Great Qin Empress's Infrastructure Handbook

Chapter 87
"Sit down, they will bring some ice in a while." Zhao Qingrui quickly invited them to sit down and rest. Over the years, she had saved some saltpeter just to keep some ice.

"My little sister has someone dig an ice cellar?" Yin Man was surprised, even in the palace, not everyone can use the ice mirror.

"No, it's too troublesome to dig an ice cellar. I have other ways to make ice." Zhao Qingrui shook her head mysteriously. In Daqin, most of the saltpeter is used to make alchemy, and some are used as medicinal materials.

Fu Su looked at Zhao Qingrui, the little girl looked very mysterious, as far as what she saw on the road, the way she brought food, saddles and stirrups, and the current method of making ice, all of these are It was something he hadn't seen before.

Soon, the iced drinks were delivered, and the mung bean smoothie made, there are not many things that can be eaten in this era.

"Hurry up, it's delicious." Zhao Qingrui scooped a large spoonful of it into his mouth with a wooden spoon. He was so satisfied that he felt the heat all over his body dissipate at once.

After taking a sip, it was sweet and icy, and Yin Man's eyes lit up, and she quickly ate it.

"It's delicious, my cook will cook a lot of delicious food, so I can eat as much as I want in the future." Zhao Qingrui looked at the two of them with a smile.

"It's really good, a holy product for relieving summer heat." Fusu nodded seriously.

After the housekeeper cleaned up their yard, Zhao Qingrui asked them to rest for a while. She was also tired after traveling for so long.

------

After sleeping until evening, when Zhao Qingrui got up, Fusu was sitting in the school on Zhuangzi, asking Zhao Wen some questions.

Yin Man was in the backyard, sitting on the swing that Zhao Qingrui had made before, enjoying herself very much by herself.

Hearing the butler's report, the corners of Zhao Qingrui's mouth twitched, aren't they all tired?
Zhao Qingrui didn't bother to take care of Fusu's side anymore, Zhao Wen's ability to deal with Fusu was no problem.

When she came to the backyard, Yinman held a small dried fish in one hand and the rope of the swing in the other, and there was a maid beside her to swing for her.

"Little sister, your swing is so fun. When I go back to the palace, I will also get one in my palace." Yin Man asked the maid to stop, and walked down excitedly.

"It's fine if you like it." Zhao Qingrui also sat on it. It's quite interesting to come here to sit and play when you have nothing to do.

Yin Man helped Zhao Qingrui push the swing, she had been playing for a while.

"Little sister, how did you come up with this, it's so fun." Yin Man couldn't put it down because of this swing.

"I asked the carpenter at home to make this because I watched others play." Zhao Qingrui said perfunctorily.

"There are so many fun things in your yard, I want to live here." Yin Man pushed the swing and said with emotion, the little girl knows how to enjoy it.

Zhao Qingrui bit the small dried fish that Yinman fed, and said generously, "It's not easy, you can come here anytime, that yard will be yours from now on, you can come whenever you want."

"By the way, I think Brother Fusu went to your Zhuangzi to read. He just couldn't stay idle. He read in your study for a while, and then someone took him to Zhuangzi. It's been an hour now. , haven't come back yet."

"I already know about this. There is a school in Zhuangzi, and he is discussing knowledge with the master there." Zhao Qingrui had a faint smile on his face.

Now Fusu was listening to Zhao Wen's lectures, which he had never heard before. Mr. Zhao's lectures were humorous, and the classroom was full of students, many of whom were from the Mo family.

Although he was shocked at first, he soon immersed himself in the knowledge Zhao Wen explained that he hadn't heard before.

In the class this afternoon, Zhao Wen is a judicial class. He talks about the purpose of legislation, and uses some laws of the current Qin Dynasty as examples to analyze their advantages and disadvantages.

Daqin's punishment is quite heavy, but its purpose is also to rule the country better and enable the country to develop better.

After class, there were a lot of things that Fusu didn't understand in class. When he asked questions, Zhao Wen would explain them to him carefully.

"That's Mr. Fusu? It looks really good-looking." Han Xin and Yan Shuang walked together and turned to look at Fusu who was still asking Mr. Zhao questions. He had heard of Mr. Fusu's famous name.

"That's right, Mr. Fusu is kind and easy to speak. Even if he says something wrong in front of him, he won't punish people easily." Yan Shuang has a very good impression of Mr. Fusu.

"Three years ago, I accidentally bumped into Mr. Fusu, and he helped me up himself."

"Master Fusu used to..."

Seeing that Yan Shuang was going to talk endlessly again, Han Xin quickened his pace.

He did not expect Zhao Qingrui's identity. He did not expect that she would be His Majesty's daughter.

However, this also made him more confident. She must have the ability to send herself to the military camp.

After he finishes learning what he needs to learn with Mr. Zhao, he can go to the military camp that he has been thinking about.

Thinking of this, Han Xin was full of motivation.

During this period of time, I learned a lot with Zhao Wenxue, which made him more confident.

Zhao Wen's erudition is the consensus of all the students in this school. He seems to understand everything. He has perfect solutions to all kinds of questions they ask.

Zhao Wen's erudition not only conquered the group of students in the school, but also conquered Fusu.

When Fusu came back, it was already dark.

"Brother, what happened to you? You came back so late." Yin Man joked.

Fusu expressed emotion, "It is true that I have gained a lot. I met a knowledgeable gentleman in my little sister's Zhuangzi."

"Little sister, this Mr. Zhao, where did you find it? Such a powerful person is actually unknown." Fusu was heartbroken. Such a powerful person should be famous all over the world, and now he is nestled in this small town. local teaching.

"He is my master's student. He only likes to teach, so I set up a small academy for him and let him teach here." Zhao Qingrui talked nonsense, but they couldn't find out anyway.

As for Zhao Wen's household registration, it was done by Lao Die's people in person, not a black household.

"There are people with such strange hobbies?" Yin Man tilted her head, and the way Brother Fu Su seemed to admire that Mr. Zhao made her even more curious.

"My little sister still has a teacher?" Fusu became even more curious.

"I know this, my little sister told me that my little sister's teacher knows the past and the future, and knows astronomy from the top and geography from the bottom. Father knows the future, so he sent Hu Hai to raise pigs." Yin Man Immediately, he told Fusu about Zhao Qingrui's mysterious master.

The more he heard it, the more something was wrong, Fusu's eyes widened, these were too outrageous.

　In ancient China, saltpeter was used very early. At the beginning, it was written as "xiaoshi", and it was used as medicine in the Warring States period.Its chemical composition is potassium nitrate.Saltpeter in nature is often formed by the decomposition of nitrogen-containing organic substances in the soil under the action of bacteria, oxidized into nitric acid, and then combined with potassium in the soil.So whenever the autumn season is high and crisp, it usually precipitates out in the shape of a shell or salt flower, covering the ground and the foot of the wall. This is the so-called ground frost.Especially in the corners near pigpens, stables, and toilets.

　　"Generated by the air of sea brine, it is the most divine thing in the world... It can turn 72 petrified into water, soften hardware, and refine eight stones. Even the Great Dan will not give up this."In the early Chinese Danjing "36 Water Methods", which came out in the Eastern Han Dynasty, saltpeter is the protagonist.
