Additional trial: Circle Cutting Technique

"Zero~! Lord Zero, why are you here!"

When the examiners saw the token in the girl's hand, their expressions changed drastically, showing signs of shock and showing great respect.

Even if they meet President Qian of the Luyang Chamber of Commerce, they will not be so frightened.

The Shang Department is one of the nine major departments in the Shenwu Continent.

The Secret Treasure Business Department is a core high-level organization within the Business Department. It is a department within a department and has only a few members. Moreover, the identity of the secret treasure merchant is kept strictly confidential and only has a code name.

Every member of the Secret Treasure Business Department has a higher status than ordinary members of the Business Department. Even President Qian of the Chamber of Commerce himself is only a member of the business department.

According to rumors, there is only one secret treasure merchant in the entire Luyang Mansion, and that is the mysterious girl code-named "Zero".

"Your level is beyond his ability."

The mysterious girl said lightly.

"That's what Master Zero taught you!"

Several examiners were extremely ashamed. They were originally angry with Ye Fan, but now they had no temper at all and did not dare to refute.

Then she took out a list and showed it to several examiners. "There are several outstanding candidates in the business department this year. I came over to see if there are any candidates who are suitable for the secret treasure department. Of the five people on this list, I We need to give them an additional test on the secret treasure system!"

 "yes!"

All the examiners immediately respectfully accepted the order.

"The following candidates, Mr. Ling will give you an additional test question. Sun Zaoli, Zhao Xing, Cao Qian...Ye Fan!"

An examiner called out all five candidates on the list.

Under the envy of all the candidates, Ye Fan, Sun Zaoli, Zhao Xing and other five people stood up and came to the front of the examination room, waiting for the mysterious girl to take the additional test.

"Congratulations on passing the preliminary screening of the business department and entering the additional examination of the 'Secret Treasure Business Department'. You are all the candidates with the best performance among the thousands of candidates in this business department assessment. You are all on the business department list. You can be among the top five. Among the more than a thousand people in the entire examination room, only five of you have been invited to take the additional examination!

However, you can easily pass the examination of the business department, but you may not have the strength to pass the additional examination of the secret treasure business department! You should also realize that the value of the secret treasure business system is far higher than that of the ordinary business system.

The additional test questions I am asking you are not from the business department, but from the secret treasure department. It's very difficult, and it rarely makes you feel desperate!

This time, I am your only examiner for the additional examination of the Secret Treasure Business Department. Those who don't want to take the secret treasure test can voluntarily withdraw! "

The mysterious girl looked at the five young candidates in front of her calmly.

No one quits, only fools quit.

Just look at the attitude of several business department examiners towards the mysterious girl, and you will know the importance of the secret treasure department.

Ye Fan was puzzled.

Secret Treasure Business Department?

He had never heard of this type of profession in the human race before? It's just that the black secret iron token in the mysterious girl's hand is made of the same material as the beast master's secret iron token. This is the most official status symbol of the human race in Shenwu Continent and cannot be faked.

Shang said to him: "The Secret Treasure Business Department is a high-level secret organization within the Business Department that rarely appears. The reason why the Business Department can become one of the nine major professions of the human race in Shenwu Continent is of course not just supported by ordinary businessmen. The core force of the business guild is the secret treasure merchants. They do not do ordinary business, but specialize in secret treasure trading! The so-called secret treasures are naturally extremely valuable rare treasures that are easily coveted by the strong. This kind of secret treasure trading is often very dangerous. , lives may be in danger at any time, so the Secret Treasure Business Department has very strict confidentiality disciplines."

Ye Fan suddenly understood.

"Very good, you have good courage! Although the five of you are the most outstanding business candidates this year, the chance of passing the secret treasure additional test is no more than one in ten thousand. It often takes many years for Luyang Mansion to give birth to a secret treasure merchant. ! Looking forward to your performance."

The mysterious girl said with satisfaction.

The five young candidates all showed excitement and extremely strong desire in their eyes.

An ultra-low probability of one in ten thousand!

There are millions of people in Luyang Mansion, and even a few candidates may not be able to join the Secret Treasure Merchant Department in a few years. Only the young people with the most outstanding talent in the business department will have the opportunity to join the secret treasure department.

This ultra-low probability is even lower than winning the top spot in the nine major categories.

If they could become a secret treasure merchant, this honor would be enough to make them proud.

"Now let's start the secret treasure series test!!"

After the mysterious girl finished speaking, she took out a slender black sword from her black robe.

All the candidates were staring at the mysterious girl, waiting for her to give the question.

The mysterious girl pulled out the slender sword, "Clang!", and a bright silver light flashed across.

The sword light flickered!

Between breaths, swish, swish, swish. A series of bright silver rays of light suddenly appeared, and a series of bright lights were drawn out quickly. These bright lights formed a circle.

All the candidates were immediately amazed.

What a sharp swordsmanship.

Those young candidates who were weak in martial arts couldn't even count how many sword lights the mysterious girl had emitted in this short period of time.

"Excuse me, it was me just now."

The mysterious girl put away her sword and asked slowly.

Zhao Xing hurriedly answered: "Master Ling! I recognize this is a set of high-level swordsmanship "Ice Soul Silver Light Sword". When the sword moves out, the pieces look like snow. When it reaches the highest level, the sword light is continuous and endless. Endless, as if the entire land is covered with flying snow. This is a high-level swordsmanship known for its dexterity and speed!"

"Shut up! This is not a martial arts exam, it does not test your eyesight. This is an additional secret treasure test, and it tests your calculation power!"

The mysterious girl gave Zhao Xing a cold look, full of ridicule.

 "yes!"

Zhao Xing immediately shut up in embarrassment, failing to show off but becoming a laughing stock.

The mysterious girl said to the others: "Just now I drew a circle in the air with my sword light. The longest point is two feet. What is the area of this circle? The time limit is one stick of incense. If no one can answer , then all will be eliminated."

Then, she picked up an incense stick on the table and lit it on the lamp.

When doing things, you have pen and paper to use for calculations.

The five teenagers immediately began to calculate. But after careful calculation, they were all shocked.

The more they calculated, the more frightened they became.

This question is too difficult.

"I know how to calculate the block-shaped land, just multiply the length by the width. But for a circle, how do I accurately calculate its size?"

"I can only make a rough calculation! But the time it takes to burn an incense stick is too short."

The five candidates were all deep in thought.

Ye Fan asked Shang in his heart: "Shang, how do you calculate this?"

Shang said calmly, "The only currently known method for calculating the land area of a circle is the 'Circle Cutting Technique', which is to cut the circle into regular polygons as much as possible. As long as there are enough sides, the area of a regular polygon circumscribed by a circle is the same as the area of a regular polygon inscribed in a circle. The difference in area can be arbitrarily small. This question is also an extremely difficult calculation question."

"Do you think the secret treasure department exam questions will be easy?"

The mysterious girl couldn't help but smile lightly when she saw that the five of them were stumped by the test questions and couldn't figure it out.

"This question is a famous eternal problem in the Secret Treasure Business Department of our Shenwu Continent. It is the pinnacle of computing power test questions. This question tests the purest computing power! This question can measure the computing power of a businessman. It can even be used to measure the overall computing power level of a human vassal state. Ordinary business departments do not need to take this kind of pure computing power test, and only we secret treasure merchants need to test this extreme computing power. Moreover, this question There is no 'correct' answer per se, only an 'approximately correct' answer. You only need to calculate an approximately correct answer within five sticks of incense time, and you have passed the examination of the Secret Treasure Business Department."

All the candidates were shocked.

I didn't expect that this test question would have such a big impact.

The mysterious girl suddenly looked at Ye Fan and said with a smile, "Do you know the answer to this question?"

She is looking forward to Ye Fan. After all, Ye Fan has three haloes: first in the martial arts department, first in the runes department, and first in the beast control department. He is known as the number one genius in the Luyang Mansion for thousands of years.

To a certain extent, what she looks forward to most is that Ye Fan can pass the examination and become a secret treasure merchant.

If Ye Fan, the most humble genius in Luyang Mansion for thousands of years, can't do it, I'm afraid it will be more difficult for other candidates to answer it.

Ye Fan was silent.

Sun Zaoli suddenly interjected at this time and said, "I know that this question requires the use of the extremely advanced arithmetic technique 'Circle Cutting Technique'. The area of a regular polygon inscribed in a circle can be infinitely approximated to the circle. The thinner the cut, the greater the loss. The area of the polygon will be smaller. If it is cut again and again, it will eventually become indivisible. This regular polygon will become one with the circle, and the area will not be lost."

The mysterious girl's eyes lit up, "Oh, so you can figure it out?"

Sun Zaoli was a little frustrated, shook his head and said: "I just know the principle of circle cutting. Although I know the method, the calculation process is extremely complicated and cannot be calculated in a short time."

The mysterious girl was slightly disappointed. She glanced at the incense and saw that one-tenth of the incense had been burned. She said, "Time is running out, so hurry up and do the math."

All the candidates understood the principle of calculating circles and hurriedly began to calculate.

One of them even thought of a clever way to cut the circle diagram into a square pattern to roughly calculate the area of the circle.

If you want to get a vague answer in just one stick of incense, this is one of the fastest ways.

If you want a more precise answer, you must cut the circle.

Sun Zaoli was also calculating quickly.

His calculation speed is the fastest. Other candidates were still immersed in calculating the regular hexagon, but he had already calculated the size of the regular dodecagon.

 "the answer is!"

Ye Fan closed his eyes and thought for a while, then suddenly said directly, "0.35 flat."

Other candidates are still immersed in calculations, and others have not even calculated the regular hexagon.

When they heard the sound, they couldn't help but raise their heads in shock, stopped their calculations, and looked at the mysterious girl one after another, wanting to know whether Ye Fan's answer was correct.

 "So fast!"

The mysterious girl was immediately surprised.

From the time she announced the test questions to when Ye Fan answered the question, it only took more than ten breaths.

This time is short, less than one-tenth of the time it takes to burn a stick of incense.

This question was the test question she took in the Secret Treasure Department examination back then. It took her a whole stick of incense to calculate the answer at the last moment when the incense was about to burn out.

 "this!"

"Why is he so fast!"

"How is it possible to mentally calculate the answer after ten breaths?!"

The other four candidates were all shocked. They stopped writing and looked at Ye Fan dumbfounded.

The principle of circle cutting is simple, and you need to keep cutting circles.

But the calculation amount is very large and cumbersome.

Not to mention the four candidates, even the mysterious girl who was the only examiner couldn't believe it.

But Ye Fan actually relied on mental arithmetic and calculated the answer directly in just ten breaths.

This mental arithmetic power is too terrifying!

Zhao Xing looked at Ye Fan dumbfounded and said, "How did you calculate it? Did you calculate it mentally, or did you just guess it randomly?"

"This must be...blindness!"

"That's right, it's only ten breaths, how can you do it mentally! I haven't even started to calculate the dodecagon."

The other candidates also had faces full of disbelief.

"Don't believe it! I definitely don't believe it. You have read a lot of books. You must have done the exact same test questions in a business book before, so you already know the results! It is actually accurate to two digits after the decimal point. How can a normal person do that? Do it in such a short time?"

Zhao Xing shouted excitedly.

Ye Fan said calmly, "This question asked by Master Ling is very sophisticated. She just drew a total of ninety-six sword rays with her sword, which was a figure that was close to a circle. For a circle For example, only by incising a regular ninety-six polyhedron can we accurately calculate to two digits after the decimal point! So for this test question, I can only calculate to two digits after the decimal point, and cannot calculate a more accurate answer. "

"You. Did you even notice how many times I fired my sword?"

The mysterious girl couldn't help but look shocked.

The art of cutting circles is the top calculation test question in the Secret Treasure Business Department of Shenwu Continent. If you want to be accurate to two digits after the decimal point of a circle, it is very particular, that is, it must be cut into a regular ninety-six polygon within the circle, and it cannot be missing one side.

So she only fired ninety-six sword lights just now.

This is also the limit of her computing power.

If you need to cut more, it may take days or even months to calculate, which is too time-consuming and energy-consuming.

"Then how do you get it to four decimal places?"

The mysterious girl asked excitedly.

"Inscribed in a regular polygon of 3072, it can be accurate to four digits after the decimal point."

Ye Fan thought for a while and said.

"Incircle three thousand and seventy-two polygons? Four decimal places! Can you calculate it?"

The mysterious girl was greatly shocked, her eyes glowing with a strange luster.

She is most familiar with the "circle cutting technique" and knows the difficulty of it best. Going from ninety-six sides to three thousand and seventy-two sides is not just a matter of adding thousands of sides.

The calculation was too difficult, and she couldn't do it even with the computing power and skills of a secret treasure merchant.

Even a business master here would not be able to calculate the results in just a few incense sticks. I'm afraid that giving the business master a month would barely make this possible.

"It can be calculated!"

Ye Fan thought for a while and nodded.

The other four mysterious candidates all opened their mouths in shock, their eyes filled with complete despair.

With their abilities, just thinking about three thousand and seventy-two regular polygons makes them feel frightened. That is simply an unattainable and distant height that can only be looked up at and cannot be reached.

Sun Zaoli looked stunned and felt palpitations.

He had just calculated the dodecagon and had not calculated the size yet.

After a while, Ye Fan had mentally calculated the size of the ninety-six polygons, and Ye Fan could even calculate a speechless three thousand and seventy-two polygons.

All the candidates present looked at Ye Fan blankly, like frosted eggplants, dejected and gave up calculations completely.

This gap is too big. Compared with Ye Fan's terrifying calculation power and mental calculation speed, their calculation power is simply scum.

"Calculate three thousand and seventy-two polygons? Four decimal places?! This. This is not a question for people to take the exam at all! Is this the terrifying gap between him and me? Do I really have no chance to surpass him in this life? , do you look down on Mark once?"

Zhao Xing raised his head sadly, completely unable to describe his mood at this moment.

He was completely desperate.

Ye Fan can just tell that the 3,072 polygons of an inscribed circle can be calculated to four digits after the decimal point. Just knowing this is far better than him countless times.

Even Sun Zaoli, who had the fastest calculation speed, only completed less than half of the calculation. Seeing that all the incense sticks were burned out, he voluntarily gave up and continued to calculate.

In the examination room, the teenagers and examiners looked at Ye Fan with great envy.

Only an extraordinary genius like Ye Fan can answer this perverted secret treasure business department additional test question of the mysterious girl.
