Madam, protect me!

Although Song Muer finally gave half of the peach to Song Ninger, Song Ninger still looked unhappy.

Li Nuo was a little embarrassed.

At this moment, he was like a biased parent who had two children at home but didn't treat them equally.

Not like that, he was indeed more biased towards Muer between the two sisters.

No matter what delicious and fun things there were, the first person he thought of was definitely Muer.

Because Muer was well-behaved.

When they first met, she would play with a fool without any disdain, would stand up for him when someone bullied him, and would say thank you sweetly after Li Nuo dressed her up.

Except for some deep-rooted decadent ideas, all the favoritism in this world is not without reason.

Absolute fairness to the two sisters is unfair to Muer.

So although Li Nuo was embarrassed to be caught in the act, he did not think he did anything wrong. He just took care of Ning'er's feelings and tried to avoid her when giving Mu'er something good next time...

Song Ning'er ran away alone after eating the peach.

Song Mu'er sat beside Li Nuo and read the book while he was reading. Occasionally, when he encountered a word he didn't know, he would ask Li Nuo.

After studying hard these days, Li Nuo had read a copy of "Shuowen". Except for some uncommon characters that still needed to be looked up in the dictionary, he had mastered most of the commonly used characters.

Song Mu'er was reading the children's enlightenment books of Daxia. Although Daxia girls could not participate in the imperial examinations, some wealthy families, especially those of officials and dignitaries, still attached great importance to the education of girls in their families.

These girls had to learn literature, mathematics, music, calligraphy and painting from an early age. They did not ask for mastery of everything, but they had to dabble in all of them.

After all, the Daxia has a strict hierarchy, and high-ranking families will only marry high-ranking families. Even if the mistress of a wealthy family is not a talented woman who is proficient in music, chess, calligraphy and painting, she cannot be illiterate...

Of course, this is just a superficial view of others.

Li Nuo turned his head and glanced at the lady who was polishing the sword in the yard, and felt that there was nothing wrong with being illiterate.

At least, when he was explaining math problems to Mu'er and her, the envy and admiration she often showed always made him feel secretly happy...

Today, Mu'er rarely asked him questions, so Li Nuo turned around and asked, "Didn't Mr. Chen assign math homework to you today?"

Song Mu'er shook her head and said, "No, Mr. Chen took a leave today and didn't come to teach us."

In fact, Li Nuo used to have a little prejudice against Mu'er's math teacher.

He thought that Mr. Chen should be the kind of old scholar who didn't know how to teach students in accordance with their aptitude, and always gave children such difficult math problems, but when he saw him yesterday, he completely changed his view of the old man.

The old man not only has a deep foundation in mathematics, but more importantly, at his age, he can still bow his head and ask a young man for advice. His attitude is so humble and polite that people can't help but admire him...

Qingfeng Academy.

Mr. Chen put his hands behind his back, looked at the three gray-haired old men, pulled the corners of his mouth, and said: "Tsk tsk..., I have explained it in such detail, you three, you still don't understand it?"

Compared with the energetic Mr. Chen, the other three old men looked particularly haggard.

At their age, no one would be energetic after staying up all night for two consecutive nights.

After a night of discussion, the three people thought they could understand the mystery.

What they didn't expect was that the three masters of Daxia mathematics, who worked together and stayed up all night, couldn't even understand other people's solutions.

I thought it was Chen's trick, but after listening to his explanation today, I felt that the difficulties were suddenly clear, and all the doubts in my heart were solved.

It is a shame to say that they have lived their whole lives, and only now do they know the subtlety of mathematics.

With their vision, it is not difficult to see that the method used by Mr. Chen to solve the problem is derived from "square field" and "Pythagorean theorem", but it is not limited to "square field" and "Pythagorean theorem", but is a brand-new mathematical method.

If this method can be improved, it will undoubtedly open up a new mathematical field in addition to "nine numbers", and his status is comparable to that of mathematical sages.

This time, the three people were convinced.

The old man surnamed Lu bowed his hands and said with a sincere heart: "I admit that I am far inferior to you in mathematics."

"I admit it too."

"In mathematics, you are good at it."

The other two old men also expressed their opinions one after another. The four of them had been arguing for a lifetime, but they did not expect that Mr. Chen, who was sixty years old, could still be enlightened. They had to admire him in addition to regret.

Mr. Chen stroked his beard and said, "It's rare that you have such awareness. If you still have any questions, please bring them all out. I will take the time to help you..."

The next morning, Li Nuo still slept until he woke up. After breakfast, he slowly went to the county government office.

He didn't sleep well last night.

Because his wife was not around.

She went to sleep with Mu'er last night, and Li Nuo slept alone in her room.

Li Nuo was actually embarrassed to always let her sleep on the floor.

He suggested sleeping on the floor himself, but she refused.

He didn't dare to invite her to sleep with him.

She was obviously not satisfied with this marriage, and Li Nuo would not make himself unhappy. He felt that this mode of getting along was not bad.

There were many unexpected cases in the county government today. Li Nuo was so busy that he didn't have time to go back for lunch at noon. He went to Pei Zhe's house for a meal. He thought he could add at least three days to his life, but until the court was dismissed in the afternoon, he didn't add a single day to his life.

I don't know if it was his illusion. These days, he always felt that trying these ordinary cases would add less and less to his life...

It shouldn't be an illusion.

Although he hasn't entered the door of the Legalist school, he is familiar with the Legalist classics and knows the Legalist practice like the back of his hand.

This is how the disciples of the Legalist school practice. At the beginning, they can increase their cultivation by solving some small cases. The more they practice, the more difficult it will be.

Those trivial cases, after reaching the third level, can play a negligible role. If you want to quickly increase your cultivation or break through the bottleneck, you must do something big.

So those big guys of the Legalist school like to kill people and their families, and they are very fond of judging the powerful...

In his case, it is very likely that he has encountered a bottleneck.

This is a bad thing, but also a good thing.

If the increase in life span has a bottleneck like cultivation, then before breaking through the bottleneck, it will be difficult for him to increase his life span by judging these small cases.

But once this bottleneck is broken, he can officially step into the door of the Legalist School and have a little self-protection power.

In addition, there is another question that confuses Li Nuo.

Steward Wu once said that the Legalist practice can be as short as one or two years, or as long as three or five years, and you can get a glimpse of the door, officially step into the door of the Legalist School, and become a Legalist disciple of the first level.

But at most, he has only been practicing Legalism for half a month, so how come he has encountered a bottleneck?
