Qian Song

Chapter 61
...

Under the bright moonlight, Li Cun saw a high-degree equation written on the paper in front of Qian!
This is not what surprised Li Cun the most.

What surprised Li Cun the most was that Qian had actually solved this high-order equation!

Moreover, Li Cun didn't understand Qian's solution at all. He could only judge based on the results that Qian's solution was correct!
As far as Li Cun knows, Wang Wensu, the mathematician of the Ming Dynasty, should be the first to solve the high-degree equation.

Even Wang Wensu was nearly 300 years earlier than the West.

I don't want to, the cheap concubine I just received has advanced this time by more than 300 years!
"This is a math genius!"

Li Cun looked at Qian as if he had found a treasure.

Qian Shi carefully considered her calculation process again, and only after she felt that there was no problem with her calculation did she put down the pen contentedly and prepared to get up.

But at this moment, Li Cun's voice sounded behind Qian's: "You don't sleep at night, so that's it?"

Li Cun thought that he would scare Qian Shi, but Qian Shi just looked back at Li Cun in surprise, and then replied without a wave: "I suddenly want to understand the Fa, and I will be unhappy if I don't write it out."

Seeing that Qian Shi didn't respect him at all, Li Cun, who had been kneeled and licked by a large group of women these days, felt a little uncomfortable, so Li Cun deliberately hit Qian Shi and said: "You do the calculations, but you are barely right. , but the method is too clumsy."

When Qian heard this, he was really hooked: "Is the general able to solve this problem?"

Li Cun knew that if he didn't show his skills, a genius like Qian would definitely not look at him seriously, even if he was her man, because this kind of genius has a sense of superiority in IQ in his bones. It is not difficult to see that she is entrusted to himself as if completing a task and now uses "I" instead of "Nujia" to refer to himself.

Li Cun didn't talk nonsense, directly picked up the pen, and solved this problem easily with the Menggen descending method that he learned when he was in college.

Seeing him, Mrs. Qian stared at Li Cun's solution method for a long time without saying a word.

——Qian's main reason is that he can't understand those strange symbols written by Li Cun.

However, Qian relied on her intuition as a genius mathematician to feel that Li Cun's solution should be correct.

Qian raised her head and looked at Li Cun with burning eyes: "General, can you explain to my family?"

Li Cun turned around and walked towards the bed, saying, "It's too late, I need to rest, um... If you can make me comfortable, I can find time to teach you how to do arithmetic tomorrow."

Upon hearing this, Mrs. Qian quickly responded, "No!", then wrapped up the quilt and chased after Li Cun...

……

Li Cun discovered that genius, although there are reasons for talent, can not be separated from personal efforts.

Such as Qian.

Last night, Li Cun, who was finally able to harm a genius, was exhausted.

But this morning, Li Cun just opened his eyes, and Qian quickly got up, trotted to take the Menggen descending method that Li Cun wrote yesterday, and asked Li Cun to explain it to her.

Li Cun felt that Qian Shi served him very comfortably, and he was happy physically and mentally, so he taught Qian Shi the Menggen method of descending order while the other women were helping him to wash up.

In fact, Li Cun just told Qian what the symbols he wrote down (such as the root sign) meant, and Qian figured out the key.

Li Cun felt that all women are trained, and geniuses are no exception.

Therefore, seeing that Qian had mastered Menggen's descending method so quickly, Li Cun asked Qian a very classic math problem he had done when he was in the Mathematical Olympiad class: "Today there is a wall ten feet thick, two mice The rats are one foot a day, and the mice are also one foot. Rats double each day, and mice half a day. Question: When will we meet again? How much do you wear?

Li Cunman thought that this problem of encountering variable-speed motion would definitely stump Qian. After all, the mathematical methods of this period were limited, and there was no such tool as the algebraic function of later generations.

But what Li Cun never expected was that after hearing that Li Cun had given her this question, Qian looked at Li Cun with a look of "this is too simple", and then said " The arithmetic method of "surplus and insufficiency" easily solved the difficult problem that made Li Cun almost cry.

Li Cun felt that his IQ was crushed, which made Li Cun very upset, so Li Cun shamelessly threw the twenty tree problem, one of the three major problems in the mathematical world, to Qian, and then left.

After several days, Qian did not appear in front of Li Cun again.

It wasn't until a few days later when Li Cun met Huo Chengfu, who had brought more than 2 state soldiers to vote for Li Cun, that Qian rushed in from the door clutching a piece of rice paper with unkempt hair and bloodshot eyes.

Seeing this, both Chen Kuutong and Huo Chengfu were taken aback!
Li Cun knew that Qian Shi must have calculated the result, but this is not the time to discuss a math problem, and Li Cun also intends to teach Qian Shi, so Li Cun glared: "I didn't see that I was talking with Huo Yuanwai, go out. "

When Qian heard this, she wanted to show Li Cun the rice paper in her hand, but she didn't dare to disobey Li Cun's words.

After hesitating again and again, Qian could only turn around and leave.

After Mrs. Qian left, Li Cun said to Chen Kuutong and Huo Chengfu with a smile: "This is my concubine, who is obsessed with calculations and made herself like this."

——Looking at Li Cun's unfaltering smile, he didn't seem to feel that Qian was embarrassing him.

Huo Chengfu is also a good person. When he saw Li Cun's performance, he knew that Li Cun must like his little concubine very much, so he said with a smile: "I like math scholars, and I like to study novel things. I think my lady will help the general to study The new weapon has made a breakthrough, so you just found it rashly?"

Huo Chengfu was actually just helping Li Cun find a way, but he inadvertently reminded Li Cun: "Since Mrs. Qian is such a genius, wouldn't it be easier for me if I asked her to help me research some advanced weapons and tools?" Conquering the world?"

Thinking of this, after sending all Chuzhou soldiers brought by Huo Chengfu to the recruit training camp, Li Cun went home immediately, ready to have a good talk with Qian.

Unexpectedly, as soon as Li Cun entered the house, he saw Qian lingering at the door.

Seeing this scene, Li Cun suddenly changed his mind about taking the initiative to talk to Qian Shi—Li Cun wanted to train Qian Shi well so that she would obey him in the future.

So, before Qian could open her mouth, Li Cun scolded her: "You come to see me without combing your hair or washing your face, how decent it is."

After that, Li Cun left.

Without time for a meal, Qian came to see Li Cun again after freshening up and dressing up beautifully.

But at this time Li Cun said again: "Is it your turn to sit in bed today? Let's talk when it's your turn."

After speaking, Li Cun took the last four young women waiting for Jin back to the room to rest.

The next day, Mrs. Qian waited for Li Cun to come home at the door, freshened up and dressed up.

This time, before Li Cun could speak first, Qian said first: "Sister Virgin and the others have promised to let the servants sleep in bed first."

After finishing speaking, Qian put his palms together and looked at Li Cun pitifully.

Li Cun reckoned that the Qian family must have paid a lot of money to get the virginity and the others joined her. It is estimated that there is also Fang Baihua supporting her, otherwise she would not be able to leave before Li Cun was about to leave. For a few days, he "possessed" Li Cun alone for one night.

Seeing that Qian's temperament was almost worn out by himself, Li Cuncai said, "We'll talk about it when we go back to the room."

Qian finally made it through, and Li Cun, being served by his wives and concubines, was comfortable, and was willing to go back to the room to rest, and then hurried into the room with her rice paper to find Li Cun.

But before Qian could open his mouth, Li Cun asked, "Do you understand the rules?"

"rule?"

After reacting for a while, Qian hurriedly went to help Li Cunkuan take off his clothes...

……

After more than an hour, Li Cuncai took the rice paper that Qian had been clutching for two days with satisfaction, and took a closer look.

Then, Li Cun couldn't help but sat up.

After looking at it for a long time, Li Cuncai turned his head to look at Qian Shi who was already sweating profusely: "Did you calculate this picture?"

Upon hearing this, Qian Shi immediately got up and asked, "Am I right?"

Li Cun asked without answering, "Do you think it's right?"

Qian Shi nodded confidently: "You are right, but..."

Li Cun took over the conversation: "But you think there are more permutations."

Qian's eyes brightened: "Is there really more rows?"

Li Cun didn't answer Qian's question immediately, but took a closer look at his amazingly talented concubine.

You must know that it was not until the sixteenth century that ancient Greece, ancient Rome, and ancient Egypt completed the sixteen-line arrangement and widely used beautiful maps in elegant decorative buildings and gorgeous arts and crafts.

But my little concubine did it five or six hundred years earlier.

"What kind of monster is this?!"

Li Cun put the rice paper aside, then hugged Mrs. Qian, and said softly, "There are still eighteen lines."

Upon hearing this, Qian was not only not disappointed, but also delighted: "There are really eighteen lines?!"

Li Cun nodded: "Not only are there eighteen lines, but there are also twenty, twenty-three lines."

This time it was Qian's turn to be shocked. She just intuitively felt that there should be eighteen more lines, but unexpectedly, there were so many lines on it!
Qian Shi immediately said: "Can the officials be counted as showing to the slave family? The slave family understands the rules."

While speaking, Qian supported Li Cun's waist and prepared to lean down.

No, this time Li Cun stopped Qian Shi: "Aside from being able to calculate, what else do you know?"

Qian said: "The slave family helped my father make water-lifting tools such as oranges, potters, dumpers, barrel cars, buckets, and scrapers. The astronomical astronomical platform, although my family has not built it yet."

After listening, Li Cun couldn't help swallowing: "Isn't this the top scientist of our time!"

Li Cun excitedly hugged Qian Shi and kissed her fiercely, and said with a big smile, "You are the treasure God gave me!"

Who would have thought that Mrs. Qian didn't understand the style at all, but asked again: "Officer, can you explain the 23th, [-]th, and [-]rd lines to my family?"

Maybe because she felt that she asked for too much, Qian changed her words again: "It's okay to explain only eighteen lines to my family."

Li Cun moved his eyes and said, "Well, let me make a few things for me, and when you make them, I will explain eighteen lines to you..."
