Although Liu Xin is now in a high position and his starting point is much higher than that of Cao Cao, Liu Bei, and Sun Jian in history, he knows in his heart that truly wanting to dominate the world cannot be achieved overnight. Historically, Yuan Shao's
Stronger than Cao Cao, but
Defeated at the hands of Cao Cao; Cao Cao was stronger than Liu Bei and Sun Quan, but failed in Chibi. There are many examples of this kind of battle in which the weak defeated the strong. There are many reasons why the stronger side lost, but they have one thing in common
The point is the lack of a clear mind.
Moreover, Liu Xin's focus is not just on defeating the heroes and dominating the world, he also has his own longer-term goals. The northern grasslands and the vast sea, these cancers that have plagued the Han nation for thousands of years, even if they cannot be
If you cut off your own hands, you will at least lay a solid foundation for future generations.
Since the New Year, Liu Xin's series of measures can only be regarded as a short-term plan, and to achieve his ambitious goals, what he needs most is talents! Although Liu Xin has also thought about setting up some kind of institution such as a recruiting institute, but
He understood that in the nearly hundred years of the Three Kingdoms' struggle for hegemony, real heroes and wise men had long since stood out, and their names would inevitably be recorded in history. Liu Xin, who came from eighteen hundred years later, was not only interested in these people
Their names, and even their personalities, have long been familiar. Even if there are one or two talented people who have been buried, and Liu Xin doesn't know about them, it doesn't matter, just treat them as fish that slipped through the net. And
, if we set up a recruiting institute now, it would easily arouse the emperor's suspicion, which would obviously outweigh the gains. Therefore, as soon as the idea came up, it was immediately rejected by Liu Xin.
Liu Xin now pins all her hopes of cultivating talents on Xiangyang Academy. Mr. Cai Yong is indeed not a simple man. He is a great scholar in his own right. At the age of more than 50, he has long passed the age of knowing his destiny, but he is still
Hungry for knowledge, he was not only interested in the mathematics taught by Ma Yun, but also in the astronomy knowledge Cai Yan learned from Ma Yun. He was indeed the best choice to head the academy.
Soon it was the day when the new semester started, and Liu Xin strolled to Cai's Mansion. He wanted to see how Cai Yong was preparing. Cai's Mansion was only a stone's throw away from Liu Xin's Prefecture and Shepherd's Mansion, but Liu Xin was still the first.
Second visit.
When he heard that Liu Xin was coming, Cai Yong hurriedly came out to greet him and said, "My lord, why are you here?"
Liu Xin said with a smile: "We have been neighbors for a long time, and we haven't visited him yet. Today I specially came to see the old gentleman."
As Cai Yong welcomed him in, he was murmuring in his heart. He always felt that he was interested in Cai Yan, but he had never heard him express it directly. He didn't know if this was the reason for his coming today.
But I heard Liu Xin say: "Uncle, school will start in a few days. Last semester was relatively short, but this year it is a full semester. How are you preparing? Are there any difficulties?"
Seeing that Liu Xin had made a special trip to learn about the academy, Cai Yong temporarily put his mind back. He was very concerned about the academy and said without hesitation: "There are no problems in other aspects. It's just that Mrs. Ma's health is not convenient, so she can't do it this year."
Next, let’s teach the students mathematics. The mathematics taught by Mrs. Ma is quite different from what I have learned in the past. I can’t find a suitable candidate to replace him for a while, and I am worried about this.”
Liu Xin couldn't help but laugh. This matter is indeed not something that Cai Yong can solve. Even if you ask him to search the entire Han Dynasty, he can't find a second person to replace Ma Yun to teach mathematics and science. Fortunately, Ma Yun's teaching is also good.
It had only been two months since the beginning, but Liu Xin still knew how to do these four simple arithmetic operations, so she said, "Don't worry about this. If it doesn't work, I can teach them myself."
Cai Yong knew that Liu Xin was highly skilled in martial arts and admired his accomplishments in poetry and prose. He did not expect that Liu Xin also knew mathematics. He was surprised and said: "The mathematics taught by Mrs. Ma is profound and profound. Is it possible that my lord is also good at this?"
Liu Xin said humbly: "I only know a little bit about it, but there is no problem in teaching children. Besides, when I encounter problems, I can go back and ask my wife for advice."
Cai Yong said hesitantly: "It's just that my lord is busy with affairs and I'm afraid I won't be able to spare time."
Liu Xin waved her hand and said: "No matter how busy you are, it can't affect the children's study. You can still spare half an hour to an hour every day."
Seeing that the problem he was most worried about was unexpectedly solved, Cai Yong said happily: "That's great. In this way, the academy will have no other problems."
At this time, Cai Yan suddenly came out. She now runs to the Prefecture Mufu almost every day, saying that she is going to listen to Liu Rui telling stories. In fact, another reason is that she wants to meet Liu Xin. Who knows that Liu Xin passed by on New Year's Eve?
, now he is preoccupied with Jingzhou affairs, and has very little time at home during the day. Now, Cai Yanzhi
She said that Liu Xin had come to her house. She would not miss such an opportunity, so she quietly walked to the front hall and hid behind the screen to eavesdrop. When she just heard that Liu Xin was also proficient in mathematics and science, she was surprised and couldn't help but come out and said:
"It turns out that your Excellency is also proficient in mathematics and science. I have a difficult problem here. I wonder if Your Excellency can solve it?"
Cai Yong was very conflicted about his daughter's meeting with Liu Xin, and hurriedly scolded: "Yan'er must not be rude!"
"Mr. Bozhe, it's okay." Liu Xin stopped Cai Yong while feeling deeply embarrassed. He knew that Cai Yan was a talented woman, and the problems in the eyes of a talented woman were probably not difficult for ordinary people, but it was difficult to retreat, so she had to force herself.
scalp
Said, "Liu is ashamed. He only knows a little about mathematics and science, not proficient in it. I don't know what problem Miss Cai has. Why don't you tell me and listen. Liu will try his best. I don't know if I can help."
I can guarantee it.”
Cai Yan took out a piece of paper, handed it to Liu Xin, and said: "This is the question on the paper. The girl racked her brains and still can't solve it."
Liu Xin took the paper from her hand uneasily and took a closer look. She saw a nine-square grid drawn on the paper, and she couldn't help but feel reassured. Although Liu Xin dropped out of school since he was a child, it was because of a sudden family change, in fact, his original academic performance was still
The more excellent one, Jiugongge, was also called Sudoku game in later generations.
Liu Xin was quite fond of this aspect when she was a child. When she grew up, she would often do Sudoku to relieve her boredom in her spare time. Unexpectedly, when she came to the Eastern Han Dynasty, people would come to ask her about Sudoku problems. Liu Xin felt more cordial and her confidence increased greatly.
He said: "Mr. Bozhe, could you please lend me some pen and ink?"
Taking the brush from Cai Yong, Liu Xin spread the paper on the table and started writing. After a while, Liu Xin gently put the brush aside and said, "Okay, Miss, let's take a look and see if it's okay."
correct?"
Cai Yan picked up the piece of paper and couldn't help covering his mouth when he saw Liu Xin's words and laughed. Although Liu Xin had practiced calligraphy for a few days when she was a child, her level of calligraphy had long since faded after so many years.
I don't know where it was thrown. In the Eastern Han Dynasty, he would dictate everything and then polish it with Jushu's pen. Although there were only a few numbers from one to nine written on the paper, they were all in traditional Chinese, which was really difficult for him.
Already.
Liu Xin blushed and said sarcastically: "Yes, my words are indeed a little..."
However, Cai Yan had stopped laughing, his eyes widened with an incredulous look, and he said in surprise: "My lord has really figured it out."
Hearing this, Cai Yong grabbed the piece of paper and looked at it carefully. Sure enough, it was not bad at all, but the words were written a little differently. He couldn't help but shake his head.
Liu Xin saw him shaking his head and asked hurriedly: "Bojie, is there anything wrong with my explanation?"
Both father and daughter are great calligraphers, so Liu Xin's calligraphy was naturally not something they could appreciate. Cai Yan already knew what his father meant when he shook his head, so he smiled and said, "No, no. This is what a folk girl learned from a book."
I saw it in an ancient book and it took me three days to solve it, but I didn’t expect you to solve it in such a short time.”
Liu Xin also smiled and said: "I used to play this kind of Jiugongge game to pass the time when I was in a small mountain village. It's not unusual to solve it occasionally. There are many kinds of Jiugongge, and this one is called the standard Jiugongge.
In addition, there are diagonal nine-square grid, number ratio nine-square grid, window nine-square grid, and the most difficult one called the killer nine-square grid."
Cai Yong and his daughter did not expect that there were so many tricks in the small nine-square grid, and they were immediately attracted by his words. Cai Yan blurted out and asked: "I wonder which small mountain village your Excellency originally lived in?"
Liu Xin was stunned by her question, but he reacted very quickly and immediately replied: "Oh, my wife and I used to live in a small place called Global Village."
"Global village!" Cai Yan exclaimed in surprise, "I heard my wife say that the land we live in is called the earth. The earth always revolves around the sun. Why is it called a global village only in your place?"
Liu Xin secretly complained, this Ma Yun really knows how to make trouble, and she has nothing to do with promoting "heliocentrism". She just told a lie casually, but she didn't expect this little girl to be more serious. As the saying goes, it takes ten to tell a lie.
What should I do now that the lies are gone? Liu Xin faltered twice and suddenly became anxious.
Zhi, said: "Well, the thing is like this. Miss also knows that most people think that the earth is flat, and the sun rises in the east and sets in the west. But we people in the global village all think that the earth is round.
The sun does not move, and the round earth revolves around the sun every day."
Cai Yong had never heard of the "heliocentric theory" theory, so he said in confusion: "No, the earth is obviously flat. If the earth is round, how can people stand on it?"
Cai Yan heard Ma Yun explain this issue. Although she didn't understand it very well, she was very willing to be her father's teacher, so she said plausibly: "Dad, I know this. My wife once told me that the relationship between objects
There is a force called universal gravitation, so people and other things are all attracted to the earth."
At this point, Cai Yan seemed to feel that there was something wrong, and said: "It doesn't seem right. You see, the adults and I are standing so close. If there is some gravitational force, why are we not attracted to each other?"
