"So, Mr. 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 heart was aroused with youthful spirit, and 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 solve them." Zhu Su looked gentle, 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 forming a formation?
Young Master, my family has a long history of learning, and I have always been diligent in studying, and I dare not slack off for a moment. How can I be compared to a playful prince like you? I must completely convince you today, so that my sister knows that his younger brother is far superior to him!
This little Highness was just born into a good child, so he has no virtues or abilities that can make my sister, who is naturally intelligent, beautiful and smart, look at her in a different light!
"Heh." Zhu Su laughed. He thought for a moment and then asked: "Then listen carefully. What I'm asking is: There are chickens and rabbits in the same cage today. There are thirty-five heads on the top and ninety-four legs on the bottom. What are the sizes of the chickens and rabbits? "
"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 can't solve it in a hurry. Please give me the solution, Your Highness." With chips, paper and pen, I should be able to solve it before sunset..."
"Slow down." Zhu Su stretched out his hand: "This is just one of the questions. There are others."
"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 met. 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?"
"This..." Xu Yungong felt sweat on his forehead. There is still some arithmetic to test when it comes to chickens and rabbits in the same cage, but when asked by "two people facing each other", it is enough to confuse people.
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!
"Do you remember clearly? I'm going to read the third question." Zhu Su saw the panic gradually appearing 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."
"Question: If pipe C is used to inlet water and pipe A is used to discharge water, how long will it take to fill the pool?"
"This... this..." Xu Yungong was sweating profusely after hearing this. He could not sort out the pipes A, B, and C. He just felt like a bunch of pipes were flying around in his mind. Even though a servant had brought the calculation chips, he could only stare blankly at the calculation chips, with his hands open, not knowing how to calculate.
He stayed there for a while, then gritted his teeth and argued: "Water is being filled in and water is being discharged 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 boy. He didn't expect that the third question would cause the child to fail.
He walked up to Xu Yungong and smiled evilly: "If you can't figure it out, you can go home and calculate it slowly. If you have any doubts, you can ask me."
"As long as I know everything, I will tell you everything, okay?"
"You..." Xu Yungong's expression froze. You said stiffly: "Can you calculate these questions?"
"Easy to do, no effort~" Zhu Su spread his hands. "For such a simple question, as long as I'm not stupid, how can I not figure it out?"
"Well..." Xu Yungong couldn't help biting his lip after hearing how lightly he said it. He said that as long as I'm not stupid, I 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 has memorized all these questions, and his competitive spirit is even higher. He can't wait to go back and read through the classics, solve these questions one by one, and attack the arrogance of the Fifth Highness.
"Um...ok." Zhu Biao touched his chin, quite absent-mindedly.
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: Zhu Su, Zhu Su, he's just a little kid, why do you have to make it so difficult for him?
If this little brother can't figure it out and is so confused, when Uncle Xu comes back and complains to the palace, Lao Zhu will have to slap my Zhu Laowu's tender buttocks with his big leather boots!
Zhu Su had no doubt at all about the lethality of these weird math application problems to the little brother... If the little brother could solve them, he would be lucky. Even in later generations, these word problems will still be the nightmare of most students in the middle of the night, something that can make children cry at night and drive parents crazy.
Its power is no less than that of Xu Da in Beiyuan...
"What a pretentious young man...Brother, let's go back to find Brother Muying quickly."
"...brother?"
Zhu Su went to tug on Zhu Biao's sleeve, but he didn't want to tug on it. Zhu Biao actually didn't move at all. Looking up, he saw Zhu Biao pinching his fingers, looking confused, not knowing what he was thinking.
"Brother? What are you doing?" Zhu Su asked.
"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. There was an unnatural blush on his face. He didn't say what he was looking for. Instead, he took a big step forward and urged Zhu Biao: "Brother-in-law must be impatient to wait. Let's go there quickly..."
"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."
"Ahem!" Zhu Biao coughed unnaturally. What's his purpose? I haven’t even figured out the topic yet! It's just that the younger brother just said that as long as he is not stupid, it will be fine. As the eldest brother, how can he afford to disgrace this person?
"Naughty! Let's go, 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 problems. But he couldn't be too embarrassed in front of his younger brother. Too bad...
…
In this way, Zhu Su settled down in the mansion of Prince Zhu Biao. Following Lao Zhu's instructions, Mu Ying came to Zhu Su's west courtyard every morning. One day is not lacking, it is the same as Yingmao. If Prince Zhu Biao has nothing to do, he often goes to the west courtyard to sit around. The three brothers may try to modify firearms or discuss ways to enrich the country and strengthen the army. Mu Ying and Zhu Biao would always be surprised and amazed by Zhu Su's occasional high-minded remarks about later generations.
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.
