"Adding one point is too much and will reduce the number of rows. Subtracting one point is not enough and is a waste of trees." Lao Zhu couldn't help but sigh after reading it several times. In his opinion, this should be the final answer. At the same time, it also meant that Han Jingyun lost, but being able to see such a beautiful scene made Lao Zhu feel it was worth it whether he lost or won.
Mr. Jin was sweating slightly on his forehead, and returned to the posture of stroking his beard. He said with a slightly tired smile: "This is my answer, fifteen lines. If you can come up with more lines, I will be the best."
Han Jingyun smiled confidently, picked up the dead branches that Lao Zhu threw on the table, first laid out a square with four trees on each side, and then placed a Bagua in the middle of the square.
He said calmly: "Sixteen lines, but this is what I came up with after thinking hard. Let the old gentleman compete with me who is well prepared in a short period of time. Jingyun will be the winner. How about it being a tie this time?"
"Wonderful, wonderful, wonderful beyond words." Mr. Jin ignored Han Jingyun's words at all. He stared at the patterns on the table and refused to move away for a moment. He was more interested than any old gourmet when he saw the delicacies of the mountains and seas. Excited.
After a while, he looked up at Han Jingyun with unfinished thoughts, shook his head and said: "Win is win, lose is lose, how can it be considered a tie? I am convinced that I lost. Besides, the arrangement of these sixteen lines, even for me, No matter how much time I have, I still can’t figure it out, and that’s it!”
Han Jingyun shook his head slightly after hearing this. Seeing Mr. Jin's confusion, he explained: "Jingyun feels that this is not the end yet. There should be eighteen or even twenty lines of arrangement, but now Jingyun also Don’t come out.”
Han Jingyun pointed to the four corners of the large square. These four points were obviously used too few times. If you want to have as many rows as possible, you will naturally want to use each tree as much as possible.
"Haha, interesting, really interesting." Mr. Jin nodded and said, "It seems that I need to think about it carefully."
After finishing speaking, he couldn't help but look up at Han Jingyun and asked, "May I ask who your arithmetic teacher is? Can you recommend someone to me?"
Han Jingyun suddenly raised his head, glanced at Han Du subconsciously, and said truthfully: "My
Mathematics was taught by my elder brother. "
Mr. Jin looked at Han Jingyun in surprise as he pointed at Han Du, and was suddenly startled. Could it be that he just didn't recognize Taishan? He immediately saluted Han Du respectfully and said apologetically: "It seems that Mr. Han is a real person and does not show his appearance. I was very rude just now, please forgive me."
Han Du quickly avoided Mr. Jin's salute, waved his hand to stop him, and said with a dry smile: "Old man, I misunderstood. In fact, my sister-in-law mainly learned mathematics by herself. Apart from giving him some mathematics books, I can't give her any guidance." What."
Seeing that neither Han Du nor Han Jingyun seemed to be cheating, Mr. Jin couldn't help but become more curious and asked: "What book? I wonder if it would be convenient for me to take a look?"
After hearing this, Han Jingyun turned to look at Han Du. Now, everyone knows that Han Du can make the decision.
Seeing the constipated expression on Han Du's face, Mr. Jin suddenly realized: "I was rash. After all, it is your master's secret skill. How can you despise others?" As he spoke, the disappointed expression on his face was almost overflowing.
Han Du felt so guilty that he could only endure the discomfort of being betrayed by his own sister, and explained with a smile: "It's not a secret skill. Since I took out these things and taught them in the academy, I never thought of hiding them." It's secretive. Although it's not a secret skill, it can't be taught casually. I hope the old gentleman can understand."
"Understood." Mr. Jin sighed and nodded, "In other words, you still can't give me a look, right?"
Han Du shook his head and said: "You can't give it to the old gentleman for no reason. If the old gentleman can enter the academy, then naturally you can let him watch it as long as he wants."
"Enter the academy?" Mr. Jin frowned slightly and asked doubtfully, "Are you asking me to enter the academy to study?"
"No~" Han Du said immediately, how dare he let Mr. Jin enter the academy to study, no matter how old he is. Even if he saves his face, he still can't do such a thing.
Romance
Besides, Mr. Jin's mathematical attainments are actually not bad, and he is also talented. It's just because he has not studied mathematics systematically that his achievements stop there. If he can get the system
With more study and research, maybe he can make further progress.
"I invite you to come to the academy to teach students. I wonder what your intentions are?" Han Du revealed his ultimate goal.
As soon as Han Du finished speaking, the happiest people were Lao Zhu and Han Jingyun.
Lao Zhu was happy that Mr. Jin rejected me at first, but he didn't expect that he would still be unable to escape from his grasp in the end.
Han Jingyun was simply happy that someone finally helped her share her teaching duties with those students.
Mr. Jin was not willing to teach in the academy. He was immersed in the world of studying arithmetic and did not value external things, otherwise he would not have refused the emperor's solicitation without hesitation.
Although fame and fortune had little appeal to him, mathematics books had a fatal temptation on him, and he was not allowed to give up as easily as he wanted to refuse the emperor's imperial edict.
After pondering for a long time, Mr. Jin still couldn't resist the temptation of mathematics books. He smiled helplessly and said: "Well, Lao Zhu has no relatives in the capital anyway, so I promise you to enter the academy and become a teacher. But you must also promise me not to hide it. Privately, you have to show me whatever I want to see."
"Haha, don't worry, Mr. Jin. If he dares to hide his secrets, I will never spare him." Lao Zhu said with a smile. He is really so happy that someone who rejected my will has returned to his service. Who is qualified enough to question the legitimacy of Ming Dynasty?
Mr. Jin smiled and shook his head, jokingly saying: "The emperor has such a talented assistant. It's too late to be happy. How can he be willing to punish him?"
Seeing that Mr. Jin didn't believe it, Lao Zhu immediately pointed at Han Du's nose and said: "Mr. Jin, don't be deceived by his innocent appearance. He is very capable, but his ability to cause trouble is even greater. And he is the most cunning, I If I don't keep an eye on him for a day, I don't know what kind of trouble he will cause. In order to deal with the aftermath for him, I am really worried and exhausted."
Lao Zhu smiled and shook his head and sighed.
Mr. Jin did not expose the emperor's self-promotion and glanced at Han Du with deep meaning.
Han Du looked embarrassed and quickly waved away.
