Just as he was about to ask the question, Zhang Yang saw Li Yue tugging at the corner of his clothes and received her look.
Zhang Yang followed her into the house, and Li Yue whispered: "Taoist Li Chunfeng's numerology is very powerful, and your numerology is also very powerful."
Looking at her curiously, Zhang Yang frowned and thought.
Li Yue said with a smile: "I know your math skills are very good, but Taoist priest Li Chunfeng is the master of math skills today. The questions cannot be too difficult to avoid losing face, and it will not be good for you."
Zhang Yang nodded clearly. In fact, there are many famous mathematical questions in the world, and pi is an endless number. If Li Chunfeng was asked to calculate pi, he would be crazy.
Not wanting to cause trouble, and not wanting to have her life too disturbed, my wife still put herself in her own shoes.
Touching her head, Zhang Yang asked puzzledly: "Do you have to tie your hair up?"
Li Yue smiled and said, "I am an adult. Aren't all women like this?"
Zhang Yang took off her hairpin and let her long, silky hair fall down her shoulders. "I still like this look. Keeping your hair tied up for a long time is not good for your hair."
Li Yue grinned, "You can do whatever you want."
"So dependent on me?"
"You are my husband!"
Li Chunfeng was waiting outside the door and didn't know what the Prince Consort and the Princess were discussing. He had studied numerology for half his life, so naturally he had no problem dealing with a young man. It also allowed him to experience the breadth and depth of numerology.
In the room, Li Yue whispered: "Just give me a slightly easier question. Whether you can calculate it depends on Taoist Master Li Chunfeng."
Zhang Yang then nodded, "Okay, for your sake."
Li Yue smiled softly.
In fact, my wife’s hair is of very good quality and very smooth. It would be bad if her hair was damaged in any way.
In the past, Li Yue was in poor health and her hair was a little yellow, but now her black hair is very beautiful.
The two walked out of the house again.
Li Chunfeng looked at the couple and said, "Have you decided on the topic?"
In the courtyard, the two people stood opposite each other. Li Chunfeng did not dare to underestimate the young man in front of him. He was able to teach Her Highness the Princess and make her solve problems so quickly. This person was not an easy person.
Zhang Yang drew an eight-by-eight chessboard with a total of sixty-four squares on the ground. "Once upon a time, there was a king who liked to play. He wanted to reward a hero and asked the hero what he wanted."
"The hero said: He wants wheat. The king asked how much wheat he needed. He said: I hope the king will put 1 wheat grain on the 1st square of the chessboard, 2 wheat grains on the 2nd square, and 3 wheat grains on the 3rd square. 4 wheat grains, 8 wheat grains are placed on the 4th square. Put them down one by one, multiplying by 2 each time. The total number of wheat grains placed in the 64 squares of the entire chessboard is the number he wants."
Zhang Yang paused for a moment and then said: "According to these conditions, how many grains of wheat are needed to fill all the grids?"
After finishing speaking, Li Chunfeng smiled and said, "What's so difficult about this?"
He was about to start counting, but when he reached the fifth square, he stopped and suddenly realized that this question was not simple.
Zhang Yang and Li Yue continued to eat roast duck, which was a high-order operation that was continuously superimposed.
"Do you know why foxes fall down so often?"
Li Yue thought for a while, "Why does the fox fall so often?"
Zhang Yang explained: "Because foxes are very cunning."
"cunning?"
"Slippery feet."
Zhang Yang looked at Li Yue's feet emphatically.
Li Yue also looked at her feet, understood, and suddenly smiled.
Li Chunfeng looked up and saw the princess and Zhang Yang smiling happily.
While calculating, this is the calculation, it should not be wrong.
After a while, Li Chunfeng scratched his head in pain, and when he counted the eighth grid, the numbers got bigger and bigger...
It was getting late, and the setting sun shone on the yard. The sunlight shone on Li Chunfeng's body, and his eyes were a little dull.
The couple had a great time playing shuttlecock. Zhang Yang asked, "Has Taoist Li Chunfeng figured it out?"
Li Chunfeng gritted his teeth and looked at his calculations.
Damn, why is it so difficult? After all, I am a master of mathematics. If I am crushed by a young man and I can't calculate, my self-esteem will not be able to bear it.
Another half an hour passed...
Li Yue collected the clothes and bedding that had been dried and said, "Taoist Master Li Chunfeng, it's getting late. You can do it tomorrow. There's no need to be in such a hurry."
Li Chunfeng stood up slowly, "Since Her Royal Highness the Princess said so, Pindao will go back first. Her Royal Highness Princess, please rest assured, Pindao will definitely figure it out."
With somewhat shaky steps, Li Chunfeng left the yard like a walking corpse.
Zhang Yang took a leisurely sip of tea.
After packing up the clothes and bedding, Li Yue said, "Is the question your husband asked difficult?"
Zhang Yang said in a low voice: "Actually, there is a story behind this question."
Hearing the word "story", Li Yue's eyes were filled with anticipation, "What story, tell me and listen to it."
"This story is about a king who likes games and a very wise hero. After the hero asked this question, the king calculated for a long time before he understood that even if he used up all the wheat in the country, he would still be able to fill the gap. Not happy with this chessboard.”
Li Yue listened patiently.
"Since the promise given by the king must be fulfilled, the reward for the hero must also be given, but after calculating it, we will know where his country will get so much food for him."
"Later, the king learned about the hero's life experience. He came from a very poor place. The king spent all his time having fun and did not know the sufferings of the people. Many people in the hero's hometown had no food to eat and many people starved to death. The king asked him what he wanted. At some point, all he wants is wheat."
"The king finally realized that what he wanted was not glory and wealth, he just wanted the people in his hometown to have enough to eat. From then on, the king stopped having fun and took care of his government affairs."
Li Yue whispered: "This is not just a math problem, it is also a story full of wisdom."
Zhang Yang added: "Actually, this story has another ending."
"What ending."
"The king can continue to complete this question, but let the hero count the wheat by himself, one by one, which will take dozens or hundreds of years... Later, the hero gave up and rebelled with a butcher knife."
Li Yue suppressed a smile, "I still like the first ending."
Zhang Yang said: "Facts have proved that not being able to reason with the king will not only bring no benefit, but will also cause harm in return."
The story of Maizi is a famous mathematical problem. The power of the numbers is constantly superimposed, and in the end it is a very large number.
At night, Li Yue took a hot bath, her face was flushed, she walked out of the room and said: "The clothes are not big enough."
Li Yue's pajamas can no longer cover her waist.
It is the most important age for growth and development.
Seeing that Zhang Yang's trousers did not cover his ankles, Li Yue sat at the table with his chin in his hand and said, "I need to make clothes again."
The light of the oil lamp shone on her little face.
Zhang Yang said: "Why don't you go buy some clothes directly."
Li Yue shook her head, "No, I want to do it myself."
"Let's go see your fief tomorrow."
"OK."
After saying that, she walked back to her room and closed the door.
It was rare that she could go back to her room to sleep, and Zhang Yang let out a sigh of relief.
It was quite warm tonight, but some cold wind would still leak in through the windows. Zhang Yang was calculating the costs and benefits.
You can first set up a breeding farm, so that you can produce and sell it for your own store, and the size of the store can also be expanded.
We can also start a furniture industry and popularize flush toilets first.
Well, that's great.
After washing up, Zhang Yang blew out the oil lamp and went to bed early.
Late at night, Taishi Bureau.
Two young eunuchs who were patrolling the palace at night passed by and saw Li Chunfeng writing something on a very huge piece of silk with a pen in his hand, and he kept mumbling.
Li Chunfeng's hair was disheveled, and from time to time a dark wind blew through here.
Seeing a strange scene in the middle of the night, the two young eunuchs quickened their pace and left the Taishi Bureau.
After walking away, the two young eunuchs talked in low voices.
"Daozhang Yuan is already half crazy and half stupid. Is this Li Chunfeng also crazy?"
"He keeps mumbling in his mouth, it's really scary."
"The monks are terrible."
"Hurry up and go back after your patrol."
…
In the Taishi Bureau, Li Chunfeng's hand holding the pen was trembling. He was writing calculations and calculating at the same time, and unconsciously read out, three hundred thousand... five thousand nine hundred...
After pouring a mouthful of cold water into his mouth, Li Chunfeng scratched his scalp in pain, "What number has it reached?"
"..."
"The twenty-ninth frame, and..."
Li Chunfeng's hand was shaking and his pen fell to the ground, "There are still thirty-five spaces left."
Not to mention calculating each cell, but also asking for the sum, this is also a huge number...
Can this be calculated by humans?
Why is there such a painful problem in this world?
"Ah!" Li Chunfeng almost broke down and roared late at night.
The most painful problem in the world is that you know how to calculate, but you just can't finish it.
Finally, Li Chunfeng swayed for a few times, feeling like the world was spinning, and finally couldn't stand and fell to the ground, motionless...
Fish belly white appears on the horizon, and the peaceful city of Chang'an under the sun gradually comes to life.
A dreamless night and a solid sleep.
Li Yue was still asleep in her room, but the two aunts got up early.
After washing up, I had to go out. I hadn’t seen Cheng Chumo and the others for a long time.
The bustle in Chang'an City is still the same.
In the early morning, there are already many pedestrians on the streets, and the festive atmosphere of the New Year has not yet passed.
Arriving at the post house, Zhang Yang walked into the room, where Li Tai and Cheng Chumo were chatting wordlessly.
"Eh? Brother Chumo, were you struck by lightning while walking on the road?" Zhang Yang looked at Cheng Chumo's hairstyle.
Where did the thunder come from so early in the morning...
Li Tai yawned lazily.
"After the court meeting, my old man asked me to follow the officers and soldiers to investigate a case. On weekdays, a certain person will also help lead the troops. He said that investigating the case can make a certain person wake up and use his wisdom."
"It's a good thing, practice your wisdom more."
"This case is also bizarre. The people from Dali Temple were vague when talking about it, and the investigation was not complete. However, they found a strange bamboo tube, which they said was physical evidence picked up on the roadside. Later, they were studying the physical evidence. When the fire broke out, I don’t know which blind person threw the bamboo tube into the fire.”
After setting off the fireworks, there may still be some gunpowder left in the bamboo tube, which is also flammable and explosive.
"Then there was a loud bang and the hair looked like this."
Zhang Yang patted Cheng Chumo and said sincerely: "Chumo,"
"Um?"
"Don't pick up things on the side of the road."
Cheng Chumo said discouraged: "I know, fortunately he is fine."
Looking at Cheng Chumo's hairstyle, Zhang Yang smiled unkindly, "Your hairstyle is quite avant-garde."
"If I hadn't just beaten up the bad guys and acted like a hero, I would have chopped off the blind people as well."
Zhang Yang cupped his hands and said, "Don't worry about it. In fact, Brother Chu Mo can be more confident. After all, you are well-known in Chang'an."
Speaking of this mileage, Mo Mo felt a little regretful, "It's a pity that guy left Chang'an overnight with Jia Xiao and Xin Ruan."
Zhang Yang smiled dryly and was speechless for a moment.
Cheng Chumo naturally did not dare to stay in Chang'an City if he offended him.
The Cheng family has a strong family style, and Cheng Yaojin is not a loser. Who dares to provoke him?
Changing his sitting position, Zhang Yang said, "By the way, where's the profit?"
Li Tai said: "We all put the money in the store, you can just go and get it yourself."
The waiters at the posthouse served wine and meat.
Li Tai took a sip of his drink and said, "The prince is really hateful."
Seeing Cheng Chumo pouring wine, Zhang Yang took away his bowl and said, "Drinking in the morning is not good for your health."
Li Tai told another bad news, and the cake business was still exposed.
The Prince of Wei's Mansion has the current crown prince's spy.
Li Tai was like a deflated rubber ball, his eyes were dull at the moment.
Zhang Yang looked at him sympathetically and said, "It's hard to guard against thieves during the day and night, so be careful in the future."
"This prince actually complained to his mother and said that the king spends all his time with businessmen! Is this the kind of person I am? He has never come out about business matters. Why does he say that!"
"Complaining is really the work of a villain."
Hearing what Zhang Yangneng said, Li Tai was a little moved, "Sure enough, heroes think alike. He is really a villain."
Li Tai is still a child with a lot of personality, but after all, the prince cannot just follow his will. In the eyes of many people, the prince should be like this, not that.
The courtiers and civil servants all wanted the prince to live the way they wanted.
But people cannot live as stereotyped as those produced by the assembly line, otherwise it would be a tragedy to lose individuality.
Li Tai scolded Li Chengqian for half an hour while drinking wine, without taking a breath.
Taking another sip of wine to moisten his mouth, Li Tai finally stopped as if he was running out of words.
"I'm a little tired. I'll scold you another day."
Li Tai let out a sigh of relief.
Zhang Yang said with emotion: "His Royal Highness the King of Wei can continue to curse for half an hour. I really admire him. Even the shrew in the street would be ashamed."
"What a shrew, I am not a shrew!"
"That's right!" Li Tai cleared his throat and said, "I'll introduce you to someone."
After speaking, he clapped his hands, and a middle-aged man walked into the room. He bowed his head humbly and bowed deeply.
Li Tai introduced: "He is Xu Jingzong, and he was also one of the eighteen bachelors in the palace of his father, Prince Qin."
Xu Jingzong was also a controversial figure in history.
This is also a smart guy.
