Countless alpacas and llamas rushed past in Ji Qiao's heart, and they were actually counted out without a shirt! That's right!

"So fast?"

"How could it be so fast!"

He hurriedly wanted to take a closer look at the strange symbols and vertical styles of Zhao Wuxian's calculations, but when he saw Zhao Wuxian's feet move, he erased them all!

Ji Qiao was so distressed that he covered his stomach, he felt that he had approached an unprecedented algorithm skill, and once he learned it, he would open a new era of mathematics!

Perhaps, as recorded in the ancient sutra, the technique of "the heavens can rise without steps, and the earth cannot be measured by size", will no longer be a legend!

He immediately put on a smiling face and said, "Little gentleman, don't mess around, tell me about this algorithm." ”

Zhao Wuxian wanted to embarrass him: "Mr. has already been admitted to the school, I don't know if the kid can be admitted to the school?" ”

"This ......"

"If Mr. can answer the kid's question, the kid will definitely give up this novel algorithm without reservation."

Ji Qiao was proud of his arithmetic skills, and there were not many opponents in the Jin Kingdom, and few arithmetic problems could stump him, so his temper also came up today, and he agreed to Zhao Wuxian's challenge in a daze.

Zhao Wuxian drew a circle on the sand table, and said: "Circle, one is the same length, the diameter of this circle is one foot long, and the circumference is unknown, can Mr. find out what is the exact area of this circle?" ”

Ji Qiao looked at it, and replied angrily: "Counting the scriptures, the diameter of Wednesday is one, the circumference is three times the diameter, and the radius of half a circumference is multiplied by the step, such a simple question, is the little gentleman underestimating me?" ”

Zhao Wuxian touched his bearded chin and smiled: "Sir, sir, in vain, you are called the first in Zhao's arithmetic, do you think the so-called Wednesday Jingyi is really accurate?" ”

Ji Qiao's heart jumped suddenly, and his eyes were suddenly different when he looked at Zhao Wuxian, the common algorithm for calculating the area of a circle at this time was actually very different, which was also a big problem that plagued many arithmetic experts and craftsmen who made wheels and potters.

But the mystery is only a mathematical god like him who can get a glimpse of it. The circumference of a circle calculated by "Wednesday Diameter One" is actually not the circumference of the circle but the circumference of the circle with a regular hexagon, and its value is much smaller than the actual circumference of the circle.

But how to find that mysterious ratio is a question that Ji Qiao has been pondering since he studied mathematics at the age of eight.

"Please teach me, little gentleman!" For Ji Qiao, the dignity of a teacher is not as important as the pursuit of the truth of mathematics, he just knelt on the ground!

Zhao Wuxian was no longer embarrassed for him, and continued to draw dots on the ground: "Sir, please see, if we can divide the circumference of the circle into six arcs on the basis of a regular hexagon in the circle, and then continue to divide each arc into two, and make a circle with a regular dodecagon, wouldn't the circumference of this regular dodecagonal be closer to the circumference than the circumference of the regular hexagon?" ”

So, if the circumference is divided finely, the less error there will be, and the circumference of the inscribed regular polygon will be closer to the circumference. And so on until the circumference can no longer be divided, and its circumference is almost exactly the same as the circumference! ”

Ji Qiao was like a boy in elementary school, he was fascinated by it, nodded his head incessantly, and sighed in his heart that Zhao Wuxian was a real genius in arithmetic, and he could think of such an ingenious method.

I hated that I wanted to stump him with that "simple" question just now, and I still wanted to point him out...... Really, it's really embarrassing, Ji Qiao just wants to find a crack in the ground to get into.

What Zhao Wuxian shows is actually circumcision, something that junior high school students in later generations will have...... But at this time, this theory had to go through more than 700 years of development, and it would not be discovered by Liu Zheng, Zu Chongzhi and others until the Wei and Jin dynasties. The Europeans were earlier, and the great scientist Archimedes came up with similar results two hundred years later, but it would have to be six decimal places until the sixteenth or seventeenth centuries.

Therefore, if Ji Qiao, a mathematician in the Spring and Autumn Period, can know, then there will be ghosts.

After releasing this cross-era theory, Zhao Wuxian clapped his hands and ran away. Verify the matter, leave it to Ji Qiao to do, let him slowly cut the circle and cut three or four thousand sides, and Wu Xi will not tell him so simply that pi is actually 3.1415926......

Ji Qiao pouted his ass excitedly, lying on the ground while drawing circles, fiddling with the tape measure, and acting as a junior high school dog to verify pi. For the first time, he felt that the calculations that he used to be like armies were so cumbersome and difficult to use......

……

After fooling Ji Qiao, Zhao Wuxian walked in the Zhao family's palace in the early morning, enjoying the rare leisure time in the past few days.

Although the lower palace is small, it has all kinds of organs, there are thousands of acres of well fields in the field, and the countrymen and savages wear calf nose pants and are shirtless in the middle of the haystacks left after harvesting. There is a towering main hall in the "country" in the city, only to see the heavy hall and the sky, the floors and pavilions, and the high platforms are connected with the steps, showing the heritage of the family for hundreds of years.

Compared with before, Zhao Wuxian's life has improved these days, and the retainers will stop saluting when they see him, and there are a few more courtiers and concubines in the living room who are a little more beautiful, but these are still not what he really wants.

You must have a territory of your own as soon as possible in order to let go of your hands and feet and break away from the shackles and rules of the Zhao Palace!

Prepare for that big war five or six years later.

There are advantages to receiving Zhao Ying's attention, but there are also disadvantages, such as Zhao Wuxian can no longer wear the hakama pleats of the Nadi people in public. The wide robe and large sleeves on the top and bottom look very pleasing to the eye, but it is really inconvenient to wear them, I really don't know how Ji Huan and the others wear more complex curved deep clothes, how they can walk flexibly and freely.

He was now planning to take some dried plums and dates to the garden to see the white elk he had caught.

That little guy is now being treated as a treasure by the whole Zhao clan, and a large deer park has been built for it, and a dozen servants are specially taken care of, expecting it to give birth to new beasts.

However, there are not many people who can get close to it, Zhao Wuxian is one, and since Ji Huan came once, I don't know if it is like the same sex attracts, the smart Bailu quickly likes the new and hates the old, and drills into Ji Huan's arms one by one. When Ji Huan saw the obedient white deer, she couldn't put it down, so she simply moved to live near the deer park, saying that she wanted to take care of it to give birth in spring next year.

Thinking of meeting Ji Huan, Zhao Wuxian couldn't help but look forward to it, he didn't understand what kind of emotion this was, there was the love of sister and brother in this life, but there was another trace of indescribable meaning.

However, halfway through, he was stopped by the vertical servant (servant) who was passing the word by Zhao Ying's side, saying that the Lord asked him to go to the main hall and discuss something.

"Something to discuss?" Zhao Wuxian's heart suddenly jumped, what could it be?

Walk straight along the avenue where two horses and chariots can be paralleled at home, pass through the hall and courtyard, and come to the main hall, which is the place where Zhao Ying handles government affairs and receives guests and retainers.

Zhao Wuxian looked up and saw that the main hall was tall and magnificent, Zhu Linghe was relieved of light, and the eaves faced with the painted Xuanniao sculpture, which was lifelike, and seemed to be about to rise and soar into the sky.

The appearance of the main hall is majestic, and the interior is also very gorgeous, there is the winding of the coiled cockroach, and there is the flying beam of the bearing of the male rainbow.

Sitting on the main seat in the hall was a middle-aged man with a beautiful beard and chest, who was Zhao Ying. He changed out of his military uniform today, dressed as a secretary of state, with a crown and a long crown, black and red, wearing a white jade ring, with a bronze long sword, and a few gilded tiger talismans representing military power were placed on the table in front of the seat.

Kneeling on both sides of the main hall in order were the three brothers of Uncle Bozhong, as well as several powerful retainers of the Zhao family, all of whom were dressed in black and with high crowns, sitting in a precarious position. Among them, there is also a doctor who wears a military attache uniform and is allowed by Zhao Ying to go to the palace with a sword.

Looking at this posture, almost all the important retainers of the Zhao family have arrived, and there must be something important to discuss.

Of course, there was one person missing, that is, Yin Duo, the housekeeper with a goatee, was still not there, probably because of the incident a few days ago and Zhao Ying. It is said that after his winter hunting, he urged Zhao Ying to immediately offer the white deer to the Marquis of Jin, but the result was naturally another quarrel, and Yin Duo threw down the words that the lord would regret in the future, and walked away.

The second position, which originally belonged to Yin Duo, was replaced by Fu Suo, a doctor with a charitable face, who was Zhao Ying's third strategist. If Yin Duo is relieved of his position as the head of the household by Zhao Ying this time, and Dong Anyu, who is in Jinyang, cannot come back for the time being, he is the most promising candidate for the position.

Speaking of which, this is the first time that Zhao Wuxian has been notified to attend a family meeting since he was a child.
