Chapter 54 You smell so good
This afternoon, Li Nuo did not have lunch at Pei Zhe's house.
Although he liked Mrs. Pei's cooking very much, he felt embarrassed to always eat at someone else's house.
Of course, the fundamental reason was that Lord Pei went out incognito today to understand the people's sentiments, and Mrs. Pei was the only one at home, so Li Nuo needed to avoid suspicion.
Even though there was a dozen years’ age difference between him and Madam Pei, marriage tended to be early in Daxia, and most people were married and had children before the age of eighteen.
Mrs. Pei has been married for many years. She is only thirty-five or thirty-six years old this year, and she still has her charm. Li Nuo doesn't want others to spread gossip.
In the past, he would avoid being alone with her.
Fortunately, the Song Mansion is not far from the county government office, so Li Nuo can go back to the Song Mansion for lunch at noon, and take a nap in his wife's room after lunch.
There haven't been many cases in the county government these days. After today, Li Nuo won't have to go there every day.
In addition to major cases, daily minor disputes can be handled together over a few days to save time and be more efficient.
He can use the saved time to read and study.
As a new arrival, there are many things that Li Nuo doesn’t understand about this world.
My father's study not only has a large collection of books, but also a complete range of types.
It involves history, geography, humanities, mathematics, music, etiquette, and various ways of cultivation... For him, it is a huge treasure trove.
After returning to the Song Mansion with Butler Wu, Li Nuo had just walked into the gate when a figure suddenly came out from the gatehouse and asked nervously, "Excuse me, is this Master Li Nuo?"
Li Nuo turned around and looked at the familiar old man. He nodded and said, "I am Li Nuo. Old man, you are..."
Mr. Chen smiled and said, "My last name is Chen, and I am Miss Mu'er's mathematics teacher."
Although he had never met Mr. Chen, Li Nuo had known him for a long time.
His impression of Mr. Chen was that he had a deep understanding of the "Nine Numbers", but was not very good at teaching. How could he assign such difficult homework to a six-year-old child?
Li Nuo asked curiously, "Mr. Chen, what can I do for you?"
Mr. Chen coughed lightly and said, "I have a math question, may I ask you, sir?"
Mr. Chen took out a piece of paper from his sleeve. Li Nuo glanced at it and was slightly stunned. Isn’t this the question that Muer asked him?
Even the words on this piece of paper were written when he was solving the problem.
Because it involved trigonometric functions, she couldn't understand it for the time being, so Li Nuo didn't explain it in detail.
He was also curious about how they solved this problem in an era without trigonometry.
After all this time, even her math teacher can't figure it out.
etc……
Li Nuo suddenly thought of something. There was no reason for Mr. Chen to give Mu'er homework for a question that he himself didn't know. So this homework was originally meant for himself?
When Li Nuo's eyes swept over him, Mr. Chen blushed and said, "I accidentally learned that there is a math expert behind Miss Mu'er, so I couldn't help but want to test her. Please don't blame me..."
Li Nuo didn't want to argue with an old man, so he asked, "I have written down the solution here, how can Mr. Chen not understand it?"
Mr. Chen immediately pointed to two of the lines and asked, "From here to here...how did you get there?"
As Li Nuo expected, what he couldn't understand was the step that introduced trigonometric functions. However, this couldn't be explained in a few words. Li Nuo said, "There is no pen here. Let's go in and talk."
The two walked into the Song Mansion and came to a courtyard.
Song Jiaren and Song Muer were practicing in the yard. Li Nuo walked to the stone table in the yard and asked Muer to get paper and pen. He first introduced the concept of trigonometric functions to Mr. Chen.
Mr. Chen is worthy of being a mathematics teacher. Mu'er could not understand these things at all, but he could accept them easily.
It is not surprising when you think about it. Daxia's mathematics already had the concept of Pythagorean theorem, and trigonometry was an extension of these basic concepts.
This question is nothing more than trigonometry, with a little bit of transformation, reduction and combination of numbers and shapes added in.
Once Mr. Chen had the concept of trigonometry, the next thing was very simple. He only needed to draw an auxiliary line and construct an angle so that its sine value was equal to a coefficient in the formula, converting the algebraic problem into a geometric problem, and the answer would be clear at a glance.
After listening to Li Nuo's explanation, Mr. Chen trembled and held the paper in his hand, speechless for a long time.
His hands were trembling slightly, and there were even tears flashing in his cloudy old eyes.
At this moment, something deep-rooted in his heart was completely overturned.
Is mathematics like this?
After studying mathematics for a lifetime, this was the first time he experienced the ultimate sophistication of mathematics.
Seeing that he hadn't spoken for a long time, Li Nuo asked, "Sir, is there anything else you don't understand?"
Although this problem can be mastered by junior high school students in later generations, it is still too advanced for today's mathematics community.
It’s normal that Mr. Chen doesn’t understand. Li Nuo can explain it to him again.
Mr. Chen came back to his senses and said immediately, "No, no, no, I really don't deserve the title of Mr., the master is the wisest one, and in mathematics, I should call you Mr.."
Before today, he only thought that Li Nuo was a quick-witted mathematical genius.
It was not until this moment that Mr. Chen realized how big the gap was between him and Li Nuo.
Even if he was given another ten or twenty years, he would not be able to come up with such a brilliant solution.
Unexpectedly, Mr. Chen was so polite. Li Nuo said hurriedly, "Mr. Chen, you are too kind, too kind..."
Mr. Chen said solemnly: "I didn't say that. It's ridiculous that I have been sitting in a well and looking at the sky all my life, claiming to be a master of mathematics. Today I know that there are people who are better than you, and there are things beyond your reach. What I have seen in the past is just a small part of mathematics..."
He clasped his hands together, bowed deeply to Li Nuo as a master and disciple, and said, "Thank you for clearing up my doubts, young master."
Li Nuo waved his hands repeatedly: "I don't deserve it, I don't deserve it..."
He knew very well that he was just standing on the shoulders of his predecessors, and Mr. Chen was just limited by the times. There was nothing to be proud of.
A figure stood not far away, staring at the scene blankly.
Song Jiaren knew that her husband was very smart, but she never expected that even Mr. Chen, the master of mathematics in Daxia, would ask him questions as a student...
Mr. Chen held the paper in his hands as if he had found a treasure, and asked Li Nuo carefully, "If I encounter any problem I don't understand in the future, can I often ask you for advice?"
Li Nuo smiled and said, "It's not that I'm asking for your advice, but we can discuss it together."
Mr. Chen said happily: "Thank you very much!"
After seeing Mr. Chen off, Song Muer ran over, hugged Li Nuo's arm, and said with twinkling eyes, "Brother Li Nuo, you are so amazing that you can even be the teacher's teacher!"
Not far away, another petite figure hid most of her body behind a tree. Looking at Song Muer who was so close to Li Nuo, she stomped her feet hard, snorted, and ran away.
While having lunch together at noon, Li Nuo secretly glanced at the lady opposite him.
Last night, he was caught when he was peeking at her while she was sleeping, which made him embarrassed for a while. Fortunately, she didn't say anything, and during the day today, it was as if nothing had happened.
It must be said that Li Nuo had a very bad first impression of her.
But after so many days of contact, his impression of her has gradually changed.
It's true that she didn't read enough books and had a cold and aloof personality, but she wasn't as violent as Li Nuo initially thought. Li Nuo later realized that it was just a misunderstanding and she couldn't be blamed entirely.
After all, she was just an eighteen-year-old girl, at the age of a flower, but she married a fool just because of her parents' unreliable promise more than ten years ago.
In later times, an eighteen-year-old girl might have just graduated from high school. If she encountered such a thing, the state would most likely intervene forcibly.
But in Daxia, this kind of thing is very common.
Even Li Nuo felt sorry for her in his heart.
Song Jiaren ate her meal in silence, and of course she noticed Li Nuo stealing glances at her from time to time.
This made her feel a little uncomfortable, and she couldn't help but think of the look she saw when she woke up last night.
From childhood to adulthood, no one except him had ever looked at her like this.
The way other people looked at her was more of fear and unwillingness, and later it was just fear.
And the feeling contained in that gaze... She didn't know how to describe it. In short, it was a novel experience that she had never had before.
After dinner, Li Nuo returned to his room and prepared for a nap.
Song Jiaren also returned to the room and sat at the table reading, still reading the "Shuowen".
Li Nuo lay in bed, tossing and turning, but couldn't fall asleep.
Although it is already August and the summer heat has arrived, it is still a bit hot at noon.
Song Jiaren heard the occasional noise behind her, closed the book, and asked, "Did the sound of turning pages disturb you?"
The occasional sound of flipping pages was actually quite hypnotic. Li Nuo shook his head and said, "No, it's just that the weather is too hot and I can't sleep..."
Song Jiaren thought about it, walked to the bed, and said, "Give me your hand."
When Li Nuo was wondering, she had already taken the initiative to hold his hand. The next moment, Li Nuo felt something cool entering his body through her palm and circling inside him. He shuddered in response, and all the heat was swept away, leaving only a cool feeling...
Li Nuo had read a lot of books in the past few days, some of which were about martial arts. He instantly understood that what his wife was practicing was a cold-attributed technique, and what had just entered his body was a stream of cold-attributed true qi.
Feeling a coolness from the inside out, Li Nuo said, "Thank you."
Song Jiaren didn't say anything, went back to the table and continued reading.
Li Nuo habitually slept with his hands as his head resting on his head, and suddenly he smelled a faint fragrance.
I've never seen her use sachets or anything like that, but she always has a faint scent like gardenia.
Li Nuo has been sleeping in her bed for the past two days and has become accustomed to the smell.
So much so that whenever he smelled this fragrance, he had an inexplicable sense of security, and even slept soundly.
He looked at his hand that his wife had just held, and subconsciously sniffed it. When he raised his head, he found a gaze from the table, and said silently: "Madam, what kind of bath powder are you using? It smells so good..."
[ps: I received a notice from the editor that the book will be published at midnight on the 14th. I still have some manuscripts in reserve. If I don’t get stuck in the writing process and use up my manuscripts in the next few days, I should be able to publish 10,000 copies a day by then. . ]
