Chapter 52 Healing
It was not even time to leave the government office when Li Nuo walked out of the county government office.
There are fewer and fewer cases every day. All the cases have been judged today, and the life expectancy has only increased by two days, which is not even a fraction of that of those second-generation officials.
It is easy to go from frugality to extravagance, but difficult to go from extravagance to frugality. After only one day, Li Nuo already began to miss them.
Butler Wu sat in the carriage. After Li Nuo got on, he asked, "Master, are you going home?"
Li Nuo shook his head and said, "No, I'm going to the Song family."
It would be too boring for him to go back alone. It would be better for him to stay at the Song's house. Not only is it close to the county government office, but Mu'er is there to entertain him. Of course, the most important thing is that at the Song's house, he can sleep with his wife at night.
On the first day he came here, he was nearly assassinated by his personal maid in his sleep. This made Li Nuo uneasy about everyone in the family except his wife and housekeeper Wu.
With his wife by his side, he slept soundly.
When Li Nuo returned to the Song family, he saw Song Muer practicing martial arts with Song Jiaren. She was waving her little fists vigorously. Every time she threw a punch, there was a dull sound in the air. Li Nuo had no doubt that she could break his bones with one punch.
Butler Wu said that sisters Song Muer and Song Ning'er both have good martial arts talents, but it seems that only Song Muer has embarked on the path of martial arts.
There are no shortcuts in the path of martial arts. Talent and hard work are both indispensable. Practicing martial arts is more difficult than practicing any other school of thought. It requires great willpower and long-term persistence to achieve success.
Most of the spoiled children of the powerful and wealthy are unwilling to endure this kind of hardship.
There are many people in Chang'an who have good martial arts talent but do not practice martial arts.
They don't need to practice hard themselves, as there are countless martial arts masters willing to come to them, bow down to them, and serve them.
Although Li Nuo himself is also one of these powerful people, he is born with insufficient innate conditions. Unlike those guys who allow their talents to go to waste, Li Nuo can only envy them.
What some people are born with but don't cherish may be what others dream of.
After watching Song Muer practice martial arts with envy for a while, Li Nuo went back to his room, got a book, and started reading in the pavilion in the courtyard.
After a while, Song Muer came running over and asked happily: "Brother Li Nuo, will you live in our house from now on?"
Song Jiaren's eyes also looked over here intentionally or unintentionally.
Li Nuo looked at her and explained, "This place is closer to the county government office, so you and Mu'er don't have to run here every day. If it's inconvenient, forget it..."
Song Jiaren didn't say anything. She knew that he had to go to the county government office every day, and she didn't think much about it. It was a bit troublesome for her to take Mu'er back and forth between the Song family and the Li family every day. It would be convenient for everyone if he lived in the Song family.
After dinner at the Song family, Song Muer brought another math problem to Li Nuo.
Li Nuo glanced at the question and did not explain it to her directly as he did before.
This is still a question related to the battlefield. Facing the sudden invasion of an enemy country, a team of Daxia cavalry needs to rush to a city to provide support in the shortest time possible.
The fastest way between the two places is to go in a straight line, but there is a desert between the military camp and the city. If the cavalry goes in a straight line, the speed will be greatly reduced. If they take a detour via the post road, although the speed will be faster, the distance will also be longer.
Now we need to find the optimal route so that the cavalry can reach the city in the shortest time.
This question is similar to the "General Drinking Horse" problem, both of which are about finding the maximum value, but the solution is completely different, and the difficulty is also increased.
If it was just a little bit difficult, it wouldn't be a big problem, but the difficulty lies in the fact that to solve this "Hu Bugui Model" problem, trigonometric functions are needed, which is something that will only be learned in the third year of junior high school in later generations.
However, Daxia's mathematics was still at the basic stage and trigonometric functions had not yet been developed.
Li Nuo vaguely remembered that trigonometry from another world was not introduced to China until the Ming Dynasty.
There is a chapter in the Mathematical Classics called "Pythagorean Theory", but the content of the study is very limited, involving only the most basic trigonometry problems.
This question seems simple, but it is actually far beyond the scope of the syllabus. With the existing means of Daxia mathematics, it is impossible to come up with an answer.
Li Nuo has taught Mu'er for so long and is very clear about her current level of mathematics and comprehension ability. This is not knowledge that she can understand at this stage.
Seeing that he hadn't spoken for a long time, Song Muer asked in surprise: "Brother Li Nuo, don't you know how to do this question?"
In her heart, Brother Li Nuo is the smartest and most intelligent person in the world.
Li Nuo shook his head and said, "It's not that I don't know how to do it. Let me try to explain it to you and see if you can understand it..."
After a moment, looking at Song Muer and Song Jiaren who looked confused, Li Nuo waved his hand and said, "Forget it if you don't understand. This question is indeed a bit difficult for you..."
He was very familiar with the levels of his wife and Mu'er, and the final result was not beyond his expectations.
Li Nuo didn't know why her mathematics teacher gave her this question. Mu'er didn't have to take the imperial examination. Besides, if this question came up in the imperial examination, no one could answer it.
It’s not that the “Hu Bugui” problem is difficult, but that a good cook cannot cook without rice. They simply do not have the relevant knowledge. Even if it only involves the content of elementary mathematics in later generations, it is an unsolvable mystery for them.
After playing Go with Mu'er for a while, the sky gradually darkened.
Li Nuo returned to his room and sat at the table, continuing to study the works of the Legalists. To his surprise, his wife was also sitting by the bed reading a book. Li Nuo took a closer look and found that she was reading Shuowen Jiezi (Shuowen Book of the Ming Dynasty)...
It seems that she still took to heart what Song Yu said to her.
This made Li Nuo feel somewhat dissatisfied with Song Yu. Isn't it just knowing a few more words? What's there to be proud of? Why did he say that about his wife? If she falls into his hands again in a fight next time, he will make sure those yamen runners whip him a few more times...
Thinking this in his mind, Li Nuo continued reading.
After these days of in-depth research, Li Nuo discovered that the Legalists were not easy to cultivate. Although they were far ahead of other schools in terms of strength, the endings of the Legalists were too tragic. Most of them died tragically, with some being torn apart by chariots, lingchi, beheaded, or skinned...
There were all kinds of torture, among which beheading was considered a light punishment, and there were basically no intact bodies.
During their practice, they offended too many powerful people, and before they died, they would often face extremely fierce revenge.
The more Li Nuo read, the colder he felt in his heart. It seemed that it wasn't that hot in the middle of summer. He felt a great shock in his heart. He closed the book and didn't want to read these horrible things anymore. He planned to take a look at the beautiful lady to relax...
When I turned around, I found Song Jiaren leaning on the bed, holding a book in her hand, but her eyes were closed.
Li Nuo shook her head helplessly. It seemed that she was not cut out for studying.
He walked over quietly, sat beside the bed, and looked at her closely.
I have to say that although the lady is uneducated and her figure is not that outstanding, her face alone can make up for all her shortcomings.
Just looking at her quietly, Li Nuo's heart, which had just been hit, was healed by 10,000 points...
Li Nuo stared in fascination until the long eyelashes on this beautiful face trembled and a pair of beautiful eyes slowly opened.
The two looked at each other for a long time, then Li Nuo looked away, looked out the window, and said with a smile: "Look, my lady, the moon is so beautiful today..."
Song Jiaren looked out the window and saw that the night sky was pitch black, with no stars or moon in sight.
