Judge of the Lamp

Chapter 69 Master Jinghan
Proud and arrogant, mediocre talent, this is Xu Zhiqiong's evaluation of Xianyue.

Although the light was dim, Xu Zhiqiong could see that Miss Xianyue bit her lip.

"You're stupid, but you're still sharp!" Xuanyue 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 have no courage, since you can't afford to lose, why do you still come to compete?

Counting is the ultimate principle of heaven and earth, how can you accommodate heaven and earth with such a small mind like yours?How to learn to be wise! "

"You..." Xianyue was so angry that she couldn't speak, Tai Bu said from the side: "Stop arguing, come up with a question quickly, this young man is very good at counting, you can't underestimate the enemy!"

With a wave of the moon, a meadow appeared in front of her eyes, and there were sheep grazing on the meadow.

"Let ten sheep graze on this piece of land, and they can eat it all in twenty-two days."

Xianyue waved again, and there were more sheep.

"It's still this land, let sixteen sheep eat it, it's only enough for ten days."

The crescent moon waved again, and there were more sheep.

"Twenty-seven sheep are called today, and the grass can be eaten in a few days!"

Xu Zhiqiong asked Tai Bu for a pen and paper to use for calculations, but Wu Xu had doubts about this question.

"Wait a minute, this question is deceitful!" Wu Xu said, "Let's say that one sheep can eat one bundle of grass a day, and ten sheep can eat for twenty-two days, which means that there are two hundred and twenty bundles on this land. Sixteen sheep ate grass for ten days, but they said there were only one hundred and sixty bales of grass, which is clearly not a piece of land!"

Xianyue sneered: "It's rare that Master Qianhu is paying attention."

After finishing speaking, Xian Yue said to Tai Bu again: "Master, such is the case with foolish people, it's useless to talk about calculations with them, but they can't even figure out the common sense between heaven and earth."

Wu Xu frowned and said, "Little pump girl, don't be so mean, tell me what's the secret behind this?"

Xian Yue sneered and said, "What can I do if I tell you? Can you understand me?"

Xu Zhiqiong said from the side: "I don't understand anything, isn't it the president of Cao?"

Xian Yue was taken aback, and Wu Xu was also taken aback.

Wu Xu asked Tai Bu: "Is this grass still growing?"

Tai Bu said with a smile: "You guys have shown clearly that this is grass and it will grow naturally, otherwise the grass in the world will not be eaten up by the sheep?"

Xianyue looked at Xu Zhiqiong, and said sarcastically, "You're not bad, I know the president of this grass, you look like someone who can herd sheep, you should be herding sheep for a lifetime, but the sheep won't think you're stupid."

She rubbed out the ball of fire and lit the incense: "I did this question when I was fourteen years old, and it took me two sticks of time. You say I'm mediocre, so I'll give you three sticks of time. If you can answer it..."

"Put out the incense," Xu Zhiqiong raised his head and said, "Twenty-seven sheep can last for five days."

Xianyue's face turned green, and the fire ball in her hand trembled with the fire: "You, you, have you done this question too?"

Xu Zhiqiong smiled foolishly: "I, I, I have never done it."

Xian Yue looked at her with tears in her eyes and said: "This fool is lying, even Senior Brother Zhixian can't calculate it so fast."

Xu Zhiqiong said: "Brother Zhixian also has the same talent as you? If he is the same as you, don't learn math anymore."

Xian Yue was furious: "Fool, what are you talking about!"

Say she can't, let alone her brother Zhixian!
Wu Xu persuaded from the side: "Little pump mother, you say that my brother has done this question, there must be evidence."

Xian Yue said: "Okay, I'll expose you now, and let me ask you, if there are fifteen sheep, when will they be able to eat all the grass?"

Xu Zhiqiong said, "Eleven days."

Xian Yue's face turned purple: "Let me ask you again, what if there are forty-nine sheep?"

Xu Zhiqiong laughed and said, "Two and a half days."

"If, if, if," Xuan Yue stuttered, "What about thirteen sheep?"

"Thirteen days and nine hours."

"If, if, if..."

Xu Zhiqiong raised his head and said, "Don't worry, the pasture originally had one hundred and ten bundles of grass, five bundles of grass grew every day, and one sheep grazed one bundle a day. I can count exactly how many sheep you said. !"

Xian Yue was dumbfounded, speechless.

Tai Bu said from the side: "Young man, who taught you the algorithm? Please tell me the truth."

Xu Zhiqiong said: "Didn't Shi just say it? Yes, there is an old woman who sells vegetables. She, she likes to cut leeks very much. She cuts one crop after another. She doesn't mind. There are so many leeks, do you have to hire someone to do it?" People come to cut? How many people are suitable to hire! Isn’t it the same as your question?”

Tai Bu was speechless.

Xu Zhiqiong turned to Xianyue and said: "This question, whether you should talk about it or not, I was 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 did it for two sticks of incense?"

Xianyue tremblingly pointed at Xu Zhiqiong and said, "You, you, you..."

Xu Zhiqiong hadn't finished speaking: "This incense is so thick, it takes at least half an hour to talk about it, just such a question, you have to do it for an entire hour, you are so talented, you really shouldn't learn to count, let's talk about it with you Zhixian Senior brother has grown leeks together for two years, maybe he can grow some skills, even if he can't learn to count, he can learn a craft, sell leeks, and make a living!"

Xianyue burst into tears, clenched her fists, and couldn't even breathe well.

Xu Zhiqiong yawned: "Any other questions?"

Wu Xu also yawned at the side, and said to Tai Bu: "Two questions, although Tai Bu can't be said to promise, he should be a shameless person."

Tai Bu stared at Xu Zhiqiong for a long time.

Xu Zhiqiong knew that Taibu was a third rank, knew that a third rank was a person who was close to a god, and knew that a third rank's cultivation could rival an army of tens of thousands.

But Xu Zhiqiong couldn't be cowardly, at this time he had to prop up the place for Qianhu.

Tai Bu said to Xianyue: "You come up with another question, don't test the school examples, only test the school to count!"

This is to go from application questions to calculation questions.

Beads of sweat appeared on Xu Zhiqiong's forehead, and the real test came.

Xianyue wiped away her tears, waved her hand, and a wheat ear appeared in front of her eyes.

She waved her hand again, and two more ears of wheat flew over: "How many ears of wheat are these?"

Wu Xu was surprised and said, "There are three plants in total, is this considered a problem?"

Three more ears of wheat flew over, and Xianyue asked again, "How many are these?"

Wu Xu blinked: "Six plants."

Four more plants flew over, and Wu Xu understood the meaning of the title.

Xianyue said: "From the beginning to nine thousand nine hundred and ninety-nine, do you know how many ears of wheat there are?"

One plus two, plus three... all the way to nine thousand nine hundred and ninety-nine!

Xian Yue only gave Wu Xu and Xu Zhiqiong the time to figure it out.

Wu Xu hurriedly asked for a pen and paper, and said to Xu Zhiqiong, "You count from front to back, and I count from back to front!"

Of course, Xu Zhiqiong couldn't do the math like this. Even if he counted one number in a second, he could count at most [-] numbers in an hour, and two people added up to [-]. How could it be possible to count it all!
But yin and yang cultivators can finish the calculation, especially those who are good at counting like Xuanyue.

Xu Zhiqiong also learned some of the mathematics of the Yin-Yang family from Tong Qingqiu. It's not as simple as Xu Zhiqiong said, but the direction of focus is different.

The study of mathematics is the pursuit of calculation ability. If Taibu really wants to do a calculation problem seriously, he can calculate faster than a computer.

However, the Yin-Yang family only pays attention to the calculation ability, not the mathematical principles, including the problems of watering the pond and grazing the sheep, which are all well-known mathematical problems of Daxuan, and the Yin-Yang family has a special formula for solving the problems.

This set of formulas for solving problems comes from the accumulated experience of repeated calculations. Of the twenty-seven sheep, which sheep will eat old grass and which sheep will eat new grass, there is a fixed number.

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 can solve problems much faster.

But in terms of pure calculation ability, Xu Zhiqiong can't compare with Xianyue. If it is her calculation, it can add from one to more than one thousand in a few minutes, and the time of one stick of incense can just be calculated.

It's a pity, if she came up with a problem and multiplied dozens of four-digit numbers together, Xu Zhiqiong would really have to work hard.

But she came up with an arithmetic sequence, so Xu Zhiqiong was not polite, and Xu Zhiqiong finished the calculation before the incense was lit.

"It adds up to four thousand nine hundred and ninety-five thousand!" Xu Zhiqiong blinked and looked at Xianyue and said, "You just think that I have done this question, and you change the number and ask again!"

Xian Yue looked at Tai Bu blankly, and Tai Bu looked at Xu Zhiqiong and said, "Young man, what's your name?"

"My name is Xu Zhiqiong, the Qiong of the sky!"

Tai Bu nodded and said: "I really didn't expect that there is such a genius in the world, Xian Yue, you admit defeat!"

Xianyue was about to grit her teeth, she stood up, pointed at Xu Zhiqiong and said: "I don't accept it! Since it's a discussion, there should be back and forth, and you come up with a problem. If I can't solve it, I will die today." in front of you."

Wu Xu waved his hands again and again and said, "Not here, not here!"

Xianyue pointed at Xu Zhiqiong and shouted: "Fool! Just come up with a question!"

This woman, relying on her talent in arithmetic, is usually used to being arrogant.

Presumably, except for her master and senior brothers in the Onmyoji Department, she has never put anyone else in her eyes.

Frustrated today, I can't hold back my face, but I'm here again!
Xu Zhiqiong must teach her a lesson.

"I only asked one question. If you can answer it, I will kowtow to you and admit your mistake. If you can't answer it, kowtow to me too!"

"Okay!" Xuan Yue agreed.

"You are considered a yin and yang cultivator anyway. I didn't care about the previous few times when you messed up. This time, you can count on your words."

Xian Yue still refuses to accept: "When did I mess around..."

Xu Zhiqiong said: "If I come up with a new question, I will insult you. I will only make up an old question. The old question you asked just now only said that there is a pool. This pool leaks, and the water can leak out in five days. , there is a bamboo dragon on top of the pool to fill the water, it can fill the water in three days..."

Before Xu Zhiqiong finished speaking, Xianyue was about to answer this question, and she still knew how to do it.

But Xu Zhiqiong didn't give her a chance to answer.

"I haven't finished the question yet. If it rains, the pond can be filled in seventeen hours. It just happens to be raining now."

Xian Yue was stunned, this question is difficult to calculate.

She solved the problem by back-to-back formulas, but Xu Zhiqiong's problem had an extra condition.

For Xu Zhiqiong, one more condition is equivalent to one more unknown and one more equation. There is no essential difference between a ternary linear equation and a binary linear equation, and it is just a bit laborious to calculate.

But for Xuanyue, who relies on experience and formulas, this is a big trouble.

She was still thinking about how to deal with the rain, but Tai Bu reminded her: "Just add a few more bamboo dragons!"

If Xianyue got something, she was going to change her formula, when she suddenly heard Xu Zhiqiong say: "There is another group of sheep coming to drink water, ten sheep can drink all the water in the pool in thirty days, now fifteen sheep have come to drink water beside the pool .”

Tai Bu reminded again: "Take it as if the water has leaked a little more."

Xianyue seems to understand but does not understand, the words are simple, but the calculation routine will change again.

Xu Zhiqiong said again: "There is a waterwheel next to the pool. Water is poured from the pool to push the waterwheel to grind wheat. It can drain the water for three hours a day and grind three hundred catties of wheat in one hour."

Tai Bu said: "Let's let some water leak again."

Xuanyue didn't respond. With her current cultivation, it was impossible to reconstruct such a complicated calculation routine.

Xu Zhiqiong said again: "The pool is half full of water now, and the bottom of the pool is leaking water, and the bamboo dragon fills the water. It can rain for half of the day, and the other half is sunny. Fifteen sheep drink water by the pool on sunny days. Two days later, seven lambs were born, and the lambs drank half as much water as the old sheep, and asked how much wheat could be ground by this pool of water when it rained after the gate was opened early in the morning!"

Tai Bu stopped talking.

Xu Zhiqiong looked at Xianyue: "The pool, the sheep, and the wheat are all mentioned by you. I will use your old question and give you a new question. Isn't it difficult for you? If you can't even solve this question Come out, are you mediocre in talent? You have to study and count for such a talent, are you wasting your time and overthinking your capabilities?"

Xianyue put down the pen and paper, and looked at Taibu.

Tai Bu remained silent.

Xianyue drew out her long sword and wanted to commit suicide.

With trembling fingers, Wu Xu snatched the long sword away and said with a sigh: "I have an agreement with your master, you are just a sparring match, why is this?"

Xian Yuesheng has nothing to love, her face is full of tears.

Tai Bu looked at Xu Zhiqiong and said, "I want to ask you one more thing, you have to tell me honestly, who is the person who taught you to count?"

Xu Zhiqiong said: "Didn't I tell you, she's an old woman selling vegetables."

Tai Bu said grimly: "If you don't tell the truth, I will never help you!"

Wu Xu sneered: "You have turned back and forth several times, but you don't care about your reputation?"

Tai Bu looked at Wu Xu: "I care about reputation, but you dare not speak out about it."

Wu Xu frowned, and what Tai Bu said was true.

Tai Bu looked at Xu Zhiqiong again and said: "Tell me where your calculation method comes from, tell me, and I will promise to help thousands of households, and I will never break my promise."

Never break your promise?

You broke your promise, what can I do?

You have pinpointed Wu Xu's vital point, knowing that he dare not speak up, but you are playing a scoundrel here!
Xu Zhiqiong looked at Tai Bu, pointed at Xianyue, and said: "If you want to say my master's name, let her kowtow to me first, it was agreed in advance!"

Xu Zhiqiong looked at Xianyue, don't think that if you want to die, you can renege on your debt!
Tai Bu said to Xian Yue: "Kowtow to this boy!"

Xianyue gritted her teeth and said, "Disciple would rather die than obey!"

Every master has such a disciple, and this is also a man who doesn't admit his words.

Tai Bu frowned, Xu Zhiqiong only felt a strange change in the surrounding environment.

Space is expanding, 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 at Tai Bu with a smile all the time.

Why is he not afraid of Taibu at all?
Does he really only have the fifth rank?

Xian Yue was terrified, she didn't dare to play tricks, so she quickly kowtowed to Xu Zhiqiong.

Tai Bu looked at Xu Zhiqiong in a blink of an eye and said, "Tell me, who is your master?"

Xu Zhiqiong looked straight and said: "My master and Tai Bu are old acquaintances!"

Tai Bu frowned, he thought of many old enemies.

Xu Zhiqiong cleared his throat and said, "Her name is Jinghan."

Tai Bu looked at Xu Zhiqiong, but didn't speak.

Wu Xu looked at Xu Zhiqiong with a puzzled look on his face.

Xian Yue raised her head and asked Tai Bu: "Master, who is Jing Han?"

Xu Zhiqiong said: "My master once said that Tai Bu likes to see her expression at that time the most, but it is so beautiful!"

Wu Xu was surprised and said: "Tai Bu, when did you talk about the expression?"

Tai Bu blinked, and said to Wu Xu: "Qianhu, I've helped you."

After finishing speaking, Tai Bu still looked at Xu Zhiqiong.

Xu Zhiqiong pretended to be coquettish and said: "Tai Bu, don't read it again, 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 say these things.
