"So, Young Master Xu is conceited about being a genius?" Zhu Su said sarcastically.
"I don't dare. Yungong just knew things earlier and enlightened a little earlier. He just knows more poems and books than most of his peers." Xu Yungong remained respectful on his face, but his youthful spirit was aroused in his heart. In his words
Confrontation.
"I really admire you for being so capable. I do have some problems here, and I would like to ask Brother Xu to explain them." Zhu Su looked warm, like a handsome young man.
"Oh? Please tell me, Your Highness, just do your best." Xu Yungong also showed humility, which was like a spring breeze blowing on his face.
Do you really want to test me? Come on, is it Confucian classics or history? Or is it the method of marching and formation?
Young Master, my family has a long history of learning, and I have always been diligent in studying. I dare not slack off for a moment. How can I be compared to you, a playful prince? Today I must completely convince you, so that my sister knows that his younger brother is far superior.
outstanding person!
This little Highness is just born into a good child. What virtues and abilities can make my naturally talented and smart sister look at me differently?
"Heh." Zhu Su laughed. He thought for a moment and asked: "Then listen carefully. What I'm asking is: Today there are chickens and rabbits in the same cage. There are thirty-five chickens and rabbits on the top and nine on the bottom.
Fourteen legs, how many are each of a chicken and a rabbit?"
"Count?" Xu Yungong was stunned. He knew that this question came from "Sun Zi Suan Jing". Although there was a solution in it, the solution was very complicated and time-consuming, so he said: "This question is easy. I just solved it in a hurry.
I can’t figure it out in time, so I ask Your Highness to give me some advice, paper and pen, I should be able to figure it out before sunset..."
"Slow down." Zhu Su stretched out his hand: "This is just one of the questions. There are others."
"...brother?"
"This..." Xu Yungong had sweat on his forehead. There is still a lot to be said for the chicken and the rabbit in the same cage, but when asked by "two people facing each other", it is quite confusing just to read it. Why does city B belong to city B and city A belongs to city A?
"Ahem!" Zhu Biao coughed unnaturally. What's his clue? He hasn't even figured out the topic yet! It's just that the younger brother just said that as long as he's not stupid, he can do it. As the eldest brother, how can he afford to disgrace this person?
"Second question: There are two people, A and B, walking along a certain official road. A is going from City A to City B, and B is going from City B to City A. The two people have different journeys. They set off at the same time. They will be on the road in six hours.
We meet. We know that it takes ten hours for A to get to City B. How long does it take for B to get to City A?"
If this little brother can't figure it out and is so confused, when Uncle Xu comes back and complains to the palace, Old Zhu will have to slap my tender buttocks, Zhu Laowu, with his big leather boots!
"Do you remember clearly? I'm going to read the third question." Zhu Su saw the panic in his eyes, smiled slightly, and then said: "There are several water pipes in a certain pool. If pipe A and pipe B are filled with water at the same time, it will take five
Hours to fill. If tubes B and C are opened at the same time, it will take four hours to fill. If tube B is opened for six hours first, it will take two hours for tubes A and C to be filled."
"As long as I know everything, I will tell you everything, okay?"
"Question: If pipe C is opened for water in and pipe A is used for outlet, how long will it take to fill the pool?"
After finally reading the entire question, he was surprised to find that even though he prided himself on being a general mathematician, he actually had nowhere to start!
"With a little effort, no effort~" Zhu Su spread his hands. "How can it be possible that such a simple question cannot be solved as long as it is not stupid?"
"Brother? What are you doing?" Zhu Su asked.
"You..." Xu Yungong's face froze. He still said stubbornly: "Can you calculate these questions?"
Seeing Xu Yungong leaving, the evil fire in Zhu Su's heart subsided. Thinking that he was actually competing with a little brother, he couldn't help but shook his head to himself: Zhu Su, Zhu Su, he is just a little kid.
, why bother to make it so difficult for him.
"Why are you so anxious?" Zhu Su had a smirk on his face: "Brother, what do you have in mind? Tell me first so I can confirm it for you."
Zhu Su went to pull Zhu Biao's sleeve, but he didn't want to pull it. Zhu Biao didn't move at all. Looking up, he saw Zhu Biao pinching his fingers, looking confused, not knowing what he was thinking.
He stayed for a while, and then he gritted his teeth and argued: "It is filling the water and draining it at the same time. How can there be such a stupid thing in the world?"
"Can't you figure it out?" Zhu Susa said with a smile. In his mind, he also prepared many more tricky application questions to make it difficult for this little kid. He didn't want to get to the third question and the kid wouldn't be able to do it.
"This...this..." Xu Yungong was sweating profusely after hearing this. He could not sort out the pipes A, B, and C. He just felt that a bunch of pipes were flying around in his mind. Even though a servant had brought it to settle matters, he could only stay blank.
He stared blankly at the calculation, with his hands open, not knowing how to calculate.
Its power is no less than that of Xu Da in Beiyuan...
Zhu Su has no doubt about the destructive power of these weird math problems on his little brother... If he can solve them, he will be a ghost. Even in later generations, these word problems will be the nightmare of most students at night, which can make them...
Children cry at night and parents go crazy.
"Ah! Oh, fifth brother. My eldest brother was just thinking about your questions... Ahem, don't get me wrong. Although your questions are difficult, I already have some ideas." Zhu Biao said, with his face on his face.
There was a hint of unnatural red color. He did not say what the specific features were. Instead, he took a big step and urged Zhu Biao: "Brother-in-law must be waiting impatiently, let's hurry over..."
"Um...ok." Zhu Biao touched his chin, quite absent-mindedly.
"What a pretentious young man... Brother, let's go back to find Brother Mu Ying quickly."
"Well..." Xu Yungong couldn't help biting his lip after hearing what he said so easily. He said that as long as he's not stupid, he can calculate it. If I can't calculate it, doesn't it mean that I have a brain disease?
"Your Highness, Yungong, please take your leave first. Please don't blame me for being disrespectful." Xu Yungong did not look at Zhu Su's provocative face, but instead saluted Zhu Biao. He had written down all these questions,
The competitive spirit in my heart is even higher, and I can't wait to go back and read through the classics, solve these problems one by one, and attack the arrogance of the Fifth Highness.
He walked up to Xu Yungong and gave a crooked smile: "If you can't figure it out, you can go home and calculate it slowly. If you have any doubts, you can ask me."
"Naughty! Let's go, let's go find our sworn brother together." Zhu Biao pushed Zhu Su and left. He had already made up his mind to read the Sutra more tonight and finally solve these three questions. But he couldn't be too embarrassed in front of his younger brother.
Too bad...
…
In this way, Zhu Su settled down in the residence of Prince Zhu Biao. Mu Ying, following Lao Zhu's orders, also came to Zhu Su's west courtyard early every morning. There was no shortage of days, just like Ying Mao. Prince Zhu
If Biao had nothing to do, he would often go to the west courtyard and sit around. The three brothers might try to modify firearms, or discuss ways to enrich the country and strengthen the army. Zhu Su would occasionally come up with some lofty views from later generations, and Mu Ying and Zhu Biao would always be surprised and amazed.
After a period of time, on this day, Zhu Su and Zhu Biao were sitting in the waterside pavilion in the garden. Crown Princess Chang was afraid that they would not be able to bear the heat, so she personally brought them several bowls of sour plum soup.
Suddenly, for no apparent reason, Mrs. Chang felt nausea in her chest and abdomen. She hurried to the pavilion and opened her mouth to vomit.
