Arrogant and mediocre in talent, this is Xu Zhiqiong's evaluation of Xian Yue.
Although the light was dim, Xu Zhiqiong could see that Miss Xianyue had bitten her lip.
"You are still stupid, but you are still sharp-tongued!" Xian Yue said angrily, "If you hadn't done this question in advance, would you have been able to answer it?"
Xu Zhiqiong sighed and said: "You, you, not only have no talent, but you also don't have the courage. If you can't afford to lose, why are you here to compete?
Counting is the ultimate principle of heaven and earth. How can your mind, which is so small, accommodate heaven and earth? How can you learn the ultimate principle?"
"You..." Xian Yue was so angry that she couldn't speak. Taibu said from the side: "Stop bickering and come up with a question quickly. This young man has a lot of math skills. You can't underestimate him!"
Crescent Moon waved her hand, and a piece of grass appeared in front of her eyes, with sheep grazing on the grass.
"If ten sheep graze on this land, they can eat it in twenty-two days."
The crescent moon waved again, and there were more sheep.
"If we let sixteen sheep eat this same piece of land, it would only be enough for ten days."
The crescent moon waved again, and there were more sheep.
"Twenty-seven sheep were called today, and they can eat all the grass in a few days!"
Xu Zhiqiong asked Taibu for paper and pen to use for calculations, but Wu Xu had questions about this question.
"Wait a minute, this question is a lie!" Wu Xu said, "Suppose one sheep can eat one bale of grass in one day, and ten sheep can eat it in twenty-two days. This means that there are 220 bales of grass on this land. Sixteen sheep ate grass for ten days, but they said there were only 160 bales of grass. This is clearly not a piece of land!"
Xian Yue sneered: "It's rare for Master Qianhu to be careful."
After saying that, Xian Yue said to Tai Bu again: "Master, this is how stupid people are. It is useless to talk to them about the principles of calculation, but they can't even think clearly about the common principles between heaven and earth."
Wu Xu frowned and said, "Little girl, don't be so mean. Could you please tell me what's the mystery behind this?"
Xian Yue sneered: "What can I do if I tell you? Can you understand it?"
Xu Zhiqiong said from the side: "What don't you understand? Isn't it just that the grass will grow?"
Xian Yue was stunned, and Wu Xu was also stunned.
Wu Xu asked Taifu: "Will this grass grow?"
Taibu smiled and said: "My disciple has shown clearly that this is grass and it will grow naturally. Otherwise, wouldn't all the grass in the world be eaten up by sheep?"
Xian Yue looked at Xu Zhiqiong and said sarcastically: "You are not bad. You know how long the grass will grow. You look like a sheep herder. You should be herding sheep for the rest of your life, but the sheep will not think you are stupid."
She rolled out a ball of fire and lit incense: "When I was fourteen, I took two sticks of incense to answer this question. You said my talent was mediocre. I will give you three sticks of incense and time. If I can answer it..."
"Put out the incense," Xu Zhiqiong raised his head and said, "Twenty-seven sheep can last for five days."
Xian Yue's face turned green, and the fire ball in her hand shivered with the fire: "You, you, have you done this question before?"
Xu Zhiqiong said with a naive smile: "I, I, I haven't done it."
Xianyue looked at it with tears in her eyes and said, "This fool is lying. Even senior brother Zhixian can't be so quick."
Xu Zhiqiong said: "Senior Brother Zhixian, does he have the same talent as you? If he is the same as you, then stop learning mathematics."
Xianyue was furious: "Fool, what are you talking about?"
It's impossible to say it to her, and it's even more impossible to say it to her senior brother Zhixian!
Wu Xu tried to persuade him: "Little Pump Girl, you said my brother has done this question, there must be some evidence."
Xianyue said: "Okay, I will expose you now, and let me ask you, if there are fifteen sheep, when will they eat up all the grass?"
Xu Zhiqiong said: "Eleven days."
Xianyue's face turned purple: "Let me ask you again, what if there are forty-nine sheep?"
Xu Zhiqiong said with a smile: "Two and a half days."
"If, if, if," Xianyue stuttered, "What if there are thirteen sheep?"
"Thirteen days and nine hours."
"If, if, if..."
Xu Zhiqiong raised his head and said: "Don't worry, there were originally 110 bundles of grass in the pasture, five bundles of grass grew every day, and a sheep ate one bundle of grass a day. I can count exactly how many sheep you mentioned.
!”
Crescent Moon was dumbfounded and speechless.
Taibu said from the side: "Young man, who taught you the algorithm? Please tell the truth."
Xu Zhiqiong said: "Didn't I just say that there is an old woman who sells vegetables? She, she especially likes to cut leeks, and she cuts them one crop after another. She just doesn't care. There are so many leeks, do I need to hire someone?
People will do the cutting? How many people should be hired? Isn’t it the same question as yours?”
Taibu was speechless.
Xu Zhiqiong turned to Xian Yue and said: "This question should be discussed or not. I was still willing to do it when I was seven years old. Cutting leeks is quite interesting. I did it while I was peeing.
But you actually made two sticks of incense?"
Crescent Moon trembled and pointed at Xu Zhiqiong: "You, you, you..."
Xu Zhiqiong hadn't finished speaking: "This incense is so thick, I can only talk about it for half an hour. Just such a question, you did it for a whole hour. You are so talented, you really shouldn't learn arithmetic, let alone you Zhixian
Senior brother, if we grow leeks together for two years, we may be able to develop some skills. Even if we can’t learn to count, we can still learn a craft and sell leeks to make a living!”
Xianyue burst into tears, clenched her fists, and couldn't even breathe.
Xu Zhiqiong yawned: "Are there any other questions?"
Wu Xu also yawned next to him and said to Taibu: "Two questions. Although Taibu is not a man of words, he should be a shameless person."
Taibu stared at Xu Zhiqiong for a long time.
Xu Zhiqiong knew that Taibu was a third-level person, that a third-level person was someone close to the gods, and that a third-level person's cultivation level could rival an army of tens of thousands.
But Xu Zhiqiong cannot be cowardly. At this time, he must hold up the place for Qianhu.
Taibu said to Xianyue: "If you ask another question, don't test the examples again, only test the calculation!"
This means moving from application questions to calculation questions.
Beads of sweat broke out on Xu Zhiqiong's forehead, and the real test was coming.
Crescent Moon wiped away her tears, waved her hand, and an ear of wheat appeared in front of her eyes.
She waved her hand again, and two more wheat ears flew towards her: "How many wheat ears are these in total?"
Wu Xu said in surprise: "There are three plants in total. Is this considered a question?"
Three more ears of wheat flew over, and Crescent Moon asked again: "How many are these?"
Wu Xu blinked: "Six."
Four more plants flew over, and Wu Xu understood the meaning of the question.
Xianyue said: "From the beginning to nine thousand nine hundred and ninety-nine, how many ears of wheat do you know?"
One plus two, plus three...all the way up to nine thousand nine hundred and ninety-nine!
The crescent moon only gave Wu Xu and Xu Zhiqiong time to figure it out.
Wu Xu quickly asked for paper and pen, and said to Xu Zhiqiong: "You count from front to back, and I will count from back to front!"
Of course it was impossible for Xu Zhiqiong to calculate like this. Even if he calculated one number per second, he could calculate up to 3,600 numbers in an hour. Two people added up to 7,200. How could this be done!
But yin and yang cultivators can do all the calculations, especially cultivators like Xian Yue who are good at counting.
Xu Zhiqiong also learned some of the math skills of the Yin Yang family from Tong Qingqiu. It is not really as simple as Xu Zhiqiong said, but the emphasis is on a different direction.
The study of arithmetic pursues calculation ability. If Taibu really wants to do a calculation problem seriously, he can calculate it faster than a computer.
However, the Yin-Yang family only focuses on calculation ability and does not pay attention to mathematical principles. Including the previously raised problems of filling the pond with water and sheep eating grass, they are all famous math problems in Daxuan. The Yin-Yang family has a special set of problem-solving formulas.
This set of formulas for solving problems comes from the accumulation of experience through repeated calculations. Among the twenty-seven sheep, which sheep eats old grass and which sheep eats new grass has a fixed number. You must strictly follow the formula and apply it step by step.
Xu Zhiqiong, on the other hand, relies on equations to solve problems. No matter how the problem changes, he can deal with it calmly, so he solves the problem much faster.
But in terms of pure calculation ability, Xu Zhiqiong is no match for Crescent Moon. If she were to calculate, she could add up the calculation from one to more than a thousand in a few minutes, and it would take just one stick of incense to complete the calculation.
It's a pity that if she asks a question where dozens of four-digit numbers are multiplied together, Xu Zhiqiong will really have to put in some effort.
But when she came up with an arithmetic sequence, Xu Zhiqiong was rude. Before the incense was lit, Xu Zhiqiong had finished the calculation.
"The total is 49,990,500!" Xu Zhiqiong blinked and looked at Xianyue and said, "Just think that I have done this question before, and you can ask another number again!"
Xianyue looked at Taibu with a blank expression, and Taibu looked at Xu Zhiqiong and said, "Young man, what is your name?"
"My name is Xu Zhiqiong, the Qiong of the sky!"
Taibu nodded and said: "I never expected that there would be such a genius in the world, Xian Yue, just give up!"
Xian Yue almost gritted her teeth. She stood up, pointed at Xu Zhiqiong and said: "I don't accept it! Since we are discussing, there will be a back and forth. Come up with a question. If I can't solve it, I will die today."
In front of you."
Wu Xu waved his hands repeatedly and said: "It's not like this, it's not like this!"
Xianyue pointed at Xu Zhiqiong and shouted: "Fool! Just come up with the question!"
This woman, relying on her talent in numbers, is usually arrogant.
She must have never taken anyone else seriously except her master and senior brothers in the Onmyoji Division.
I suffered a setback today and I can’t keep my face on it, but I’m here again!
Xu Zhiqiong must teach her a lesson.
"I only ask one question. If you can answer it correctly, I will kowtow to you and admit your mistake. If you can't answer it, you will also kowtow to me!"
"Okay!" Xianyue agreed.
"You can be considered a yin-yang cultivator after all. I won't care about the few times you acted like a fool in the past. This time, you must keep your words."
Xianyue is still dissatisfied: "When have I ever cheated..."
Xu Zhiqiong said: "If I ask a new question, but I am bullying you, I will only ask an old question. The old question you asked just now only said that there is a pool. This pool leaks water and can leak all the water in five days.
, there is a bamboo dragon filling the pool with water, and it can be filled with water in three days..."
Before Xu Zhiqiong finished speaking, Xian Yue was about to answer. She could still do this question.
But Xu Zhiqiong didn't give her a chance to answer.
"We haven't finished the question yet. If it rains, the pond can be filled in seventeen hours. It's just raining now."
Xianyue was stunned, this question was not easy to solve.
She relied on formulas to solve the problem, but there was an additional condition in Xu Zhiqiong's question.
For Xu Zhiqiong, one more condition is equivalent to one more unknown number and one more equation. There is no essential difference between a linear equation of three variables and a linear equation of two variables. It is just a little laborious to calculate.
But for Xianyue, who relies on experience and formulas, this is a big problem.
She was still thinking about how to deal with the rain problem, and Taibu reminded her: "Just think of it as adding a few more bamboo dragons!"
If Xianyue gained something, he was going to change his formula, but suddenly he heard Xu Zhiqiong say: "There are still a group of sheep coming to drink water. Ten sheep can drink all the water in the pond in thirty days. Now fifteen sheep are coming to drink water next to the pond."
.”
Taibu reminded again: "Just pretend that there is too much water leaking."
Crescent Moon seems to understand, but the words are simple, and the calculation routine is about to change again.
Xu Zhiqiong added: "There is a waterwheel next to the pool. Water is released from the pool to push the waterwheel to grind wheat. The water can be drained out in three hours a day, and three hundred kilograms of wheat can be ground in one hour."
Taibu said: "It seems that some water leaked again."
Xianyue didn't respond. With her current level of cultivation, it was impossible to reconstruct such a complicated calculation routine.
Xu Zhiqiong added: "This pool is half full of water now. The bottom of the pool is leaking, and the bamboo dragons are filling the water. It rains half the day and is sunny half the day. Fifteen sheep drink water next to the pool on sunny days.
Two days later, seven lambs were born. The lambs drank half as much water as the old lambs. After opening the gate in the early morning, it happened to rain. How much wheat can be ground in this pond of water!"
Taibu stopped talking.
Xu Zhiqiong looked at the crescent moon: "Pond, sheep, and wheat are all what you said. I will use your old question and give you a new question. Isn't this difficult for you? If you can't even do this question
Come out, are you mediocre in talent? With such talent, you have to study calculations, are you wasting your time and overestimating your abilities?"
Xianyue put down the pen and paper and looked at the divination.
Taibu still remained silent.
Xianyue pulled out her sword and wanted to commit suicide.
Wu Xu trembled with both fingers, snatched the long sword away, and sighed: "Your master and I have an agreement, you are just having a sparring match, why is it like this?"
The crescent moon is full of love, and my face is full of tears.
Taibu looked at Xu Zhiqiong and said, "I still want to ask you something. You have to tell me honestly, who is the person who taught you counting?"
Xu Zhiqiong said: "Didn't I tell you that she is an old woman selling vegetables?"
Taibu looked ferocious and said: "If you don't tell the truth, I will never help your family!"
Wu Xu sneered: "You have gone back on your word several times, but you don't care about your reputation?"
Taibu looked at Wu Xu: "I care about my reputation, but you don't dare to tell me about it."
Wu Xu rolled his eyes, what Taibu said was indeed correct.
Taibu looked at Xu Zhiqiong again and said, "Tell me where your calculation method comes from. If you tell me, I will promise to help thousands of your families and I will never break my promise."
Never break your promise?
What can I do if you break your promise?
You have grasped Wu Xu's key point, knowing that he dare not speak out, yet you are acting rogue here!
Xu Zhiqiong looked at the Taifu, pointed at the crescent moon, and said: "If you want to tell my master's name, let her kowtow to me first. This was agreed in advance!"
Xu Zhiqiong looked at the crescent moon, don't think that just because you want to die, you can default on your debt!
Taibu said to Xianyue: "Kowtow to this young man!"
Xianyue gritted her teeth and said, "This disciple would rather die than obey!"
Like a master, there is a disciple, and this is also a man who refuses to accept his words.
Taibu frowned, and Xu Zhiqiong felt strange changes in the surrounding environment.
The space is enlarging and sometimes shrinking.
Is this the method of the third-grade Yin Yang family? Can he change space?
Xu Zhiqiong was very nervous, but Wu Xu looked normal and kept looking at Taibu with a smile.
Why is he not afraid of Taifu at all?
Does he really only have a fifth grade?
Xian Yue was frightened and did not dare to act recklessly, so she quickly kowtowed to Xu Zhiqiong.
Taibu turned his eyes and looked at Xu Zhiqiong and said, "Tell me, who is your master?"
Xu Zhiqiong looked serious and said: "My master and Taibu are old acquaintances!"
Taibu frowned, remembering many of his old enemies.
Xu Zhiqiong cleared his throat and said, "Her name is Jinghan."
Taibu looked at Xu Zhiqiong and said nothing.
Wu Xu looked at Xu Zhiqiong with a puzzled expression.
Xianyue raised her head and asked Taibu: "Master, who is Jinghan?"
Xu Zhiqiong said: "My master once said that Taibu liked to see her expression at that time the most, but she was so delicate and beautiful!"
Wu Xu said in surprise: "Taibu, what time of expression are you talking about?"
Taibu blinked and said to Wu Xu: "Qianhu, I helped you."
After saying that, Taibu still looked at Xu Zhiqiong.
Xu Zhiqiong pretended to be coquettish and said: "Taifu, don't read it anymore, it's embarrassing!"
Old man, I know how many scars and marks you have on your body, whether they are long or short, and what posture you like.
As long as Wu Xu is not afraid of you, I still dare to speak out about these things.
