The heavens begin with Hongquan

The next day.

"Comparing formations?"

After Yelu Chucai looked at Yan Kang, his expression seemed a little strange.

He knew about the gambling fight between Huang Yaoshi and Wan Yankang, so out of curiosity, he came to the palace early in the morning.

"Yes, it's the formation."

Yaoshi Huang exudes strong confidence.

When it comes to martial arts, he may not be the best in the world, but when it comes to calculations and formations, even the [Tiangang Beidou Formation] left by the immortal Chongyang Master is nothing more than that in his eyes.

"But how do we compete in battle formations? Do we need to form a formation? How many men and horses are needed?" Wan Yankang asked.

"Both the troops and the formation base are too troublesome." Huang Yaoshi shook his head, "The basis of the formation is the method of arithmetic, so we directly compare the ability of arithmetic."

"Okay, just follow Island Master Huang."

Then, ask Hongyu to prepare pen and paper.

Huang Yaoshi was heartbroken when he saw Wanyankang agreeing so simply.

Ever since he was easily aroused and saddened the day before yesterday, Huang Yaoshi didn't dare to underestimate Wan Yankang.

Paper and pens were placed on the stone table in the courtyard.

"Island Master Huang, please." Wan Yankang extended his hand to signal.

"My first question: Arrange the nine numbers from one to nine in three columns. Regardless of the vertical, horizontal and oblique angles, the sum of each three characters is fifteen. How to arrange them?"

Huang Yaoshi first asked questions that he thought were relatively simple to test the opponent's arithmetic skills.

Wan Yankang blurted out: "The meaning of the nine palaces is based on the turtle, two and four are shoulders, six and eight are feet, three on the left and seven on the right, nine shoes on one, five in the center."

Huang Yaoshi looked over deeply.

"If you can tell me this, it seems that you have also specialized in arithmetic."

"The divine dragon came out of Luoshui carrying the picture, and the colorful phoenix held the book in the blue clouds. Because of the fate of the wind, it was written down, and the Dunjia Qimen began." Wanyankang smiled lightly and said: "Master Huang, to be honest, if you want to win against me , but this level of difficulty is not enough.”

Listening to the other party's confident and slightly arrogant tone, Huang Yaoshi snorted slightly.

"Then what do you think is the ancestor of divination?"

Wanyan Kangdao: "Some people say that Luoshu Jiu Shu is the ancestor of arithmetic, but in my opinion, arithmetic should be divided into ancient and modern times."

Huang Yaoshi was curious: "I would like to hear the details."

Wanyan Kang replied: "There are three ancestors of ancient arithmetic, Hetu, Luoshu, and Five Elements. Hetu is transformed into Bagua, and Bagua is transformed into sixty-four hexagrams. Each hexagram contains a small nine palaces."

"The nine palaces are divided into odd and even numbers of yin and yang. This is taken from the principle of yin and yang in the river diagram. There are forty-five directions in the nine palace diagram, and each location contains a gossip..."

Apart from Huang Yaoshi, only Huang Rong and Yelu Chucai could understand his explanation somewhat.

As for the others?

Haha, I can understand every word, but after being connected into a sentence, it means that the two of them don't know each other.

Huang Yaoshi raised his head with a happy face.

He suddenly became excited.

Wan Yankang's remarks showed that he was an expert in arithmetic.

At this moment, Huang Yaoshi had an inexplicable feeling that he was about to meet a talented person. On weekdays, there is no one with whom he can discuss the art of arithmetic.

then.

Huang Yaoshi put forward the "question of Shao Guang", "the question of business success", "the question of surplus and deficiency", "the question of equation", "the question of Pythagorean", "the question of cube" and "the question of decline and division" , "Fang Tian's question"...

All were quickly answered by Wan Yankang.

He looked so relaxed and at ease, as if he had a small skill.

See this.

Huang Yaoshi sat down and his attitude became serious.

I picked up the pen and drew several pictures on the paper solemnly, asking questions while drawing.

"In that case, come and see this [Explanation of the Creation of Heaven and Earth]."

"Twenty-five is the number of days. The middle is three-five-nine, and the outer part is fifteen, which is the position of three days, five days, nine and fifteen. The back shape of one-six has no place, and it shows that twenty-four is used. This is what the sky is like.”

"The bottom thirty is the number of the earth, and it is also divided into five positions, all of which understand the use of the five. The tenths are divided into six, which are the images of the form and the earth. The six are divided into four images, and the six of the earth are not suitable. The upper ones are one that is not suitable, and the form is two. Fourteen. In the following, six is ​​not used, and it also forms twenty-four."

"Afterwards, it is combined. The sky is at the top and is the sect of Tao. The six earths at the bottom are the root of the earth... Please give a brief outline." Huang Yaoshi continued to write and draw.

Others only felt a "buzzing" sound in their ears.

who I am? Where am I? What am I doing?

Even Yelu Chucai and Huang Rong couldn't understand it now. They only knew that it seemed to be something that calculated the "coincidence of heaven and earth".

Huang Yaoshi looked at Wan Yankang with a hint of pride.

It took him more than a month to figure out this [Explanation of the Generation of Heaven and Earth].

After Wanyankang listened, it only took him three breaths before he picked up the pen.

Huang Yaoshi's brows suddenly jumped.

"The question of Island Master Huang is indeed profound, but what if we understand it this way?"

"If you compare the chips, set up the yang chip on the left and the yin chip on the right. Then the number on the left is one, three, five, seven, nine, and the number on the right is two, four, six, eighty, half on each side.

Combining them together, let's set the raw number on the left and the established number on the right. Then the left is one, two, three, four, five, and the right is six, seven, eight, ninety, which is half and half. They all come together to achieve each other, and then something comes into being. "

"Therefore, one yang from the left combines with the six yins on the right, and water is formed. Three yangs from the left combine with the eight yins on the right, and wood is formed... Therefore, they match each other, just like Zi and Wu are opposite each other, and they are spouses. It's a set example. Because the positions are equal and the numbers are similar, they can be combined and the result of their creation can be seen."

"...the numbers covering the five elements, including the meaning of numbers. One shows the components of yin and yang, one shows the order of generation, one shows the measurement of the five elements, one shows the total number of divisions and sums of the two qi, and one shows the original number of two and five. …”

"...So there are quantities and numbers, and you can distinguish what they are. And things will be regenerated into other things, and Qi will be transformed into different Qi, and there will be a certain number of days from now on."

He wrote, drew and talked for almost two quarters of an hour. He used hundreds of pieces of blank paper before Wanyankang put down the pen and paper.

now.

The scene was completely silent.

Everyone stared with their eyes wide open and their mouths opened wide, feeling that their minds were blank. It was clear that countless words had entered my mind just now, but they slipped out without stopping at all.

That feeling is called "clear"!

But Huang Yaoshi was different.

His expression was excited, his eyes were shining, and his body was shaking involuntarily.

“So it can still be like this!”

“It turns out it can still be calculated like this!!”

He picked up the blank paper and began to calculate.

"The total number of the river map is fifty-five, of which twenty-five belong to heaven, which is the product of yang numbers; and thirty of them belong to earth, which are the product of yin numbers, that is, one yin and one yang. The difference between them is five, This is the untransformed vitality. Although it is in heaven and earth, it is not among the fifty-five."

"...Gai can be named but not nameless, and can be counted but countless. Therefore, it is the middle qi, which is the number of differences between yin and yang. However, the innate first appearance of life and transformation is disordered and memorable, and it is infinite and countable. There is a difference but no difference, there is Accumulation but no accumulation. Covered by the difference between yang and yin, it is only between movement and stillness."

Huang Yaoshi's behavior was like being possessed by a demon.

Can Huang Yaoshi be so disgraceful, and what the Crown Prince wrote is so powerful?

Everyone was speculating in their minds.

"I see!"

"You calculated from "the positions where the heaven and the earth have been combined", and then deduced the "number of the places where the heaven and the earth have not been combined" until you calculated the "number of how the heaven and the earth were created." What a wonderful idea, a wonderful idea!"

Not just a whimsical idea, this kind of problem-solving idea can be said to be a return to nature.

Only those who understand know how perfect Wanyankang's solution is.

"Island Master Huang, is it my turn to ask questions now?"

"……please."

Arithmetic is not like some policy articles, poems and songs. If you don't know how to do it, you can still say a few words. If someone cheers you up, you may even brag.

When it comes to arithmetic problems, if you can do it, you can do it, and if you can't do it, you can't do it. You can't do it falsely.

Through the question just now, Huang Yaoshi already knew Wanyankang's level, but he still had some luck. His arithmetic skills were profound and profound, and no one dared to say that he knew everything.

Wan Yankang drew a big river on the paper, with a few strokes, showing the momentum of the surging waves.

As Huang Yaoshi approached, he saw a math problem called "River Controlling Map".

“Calculate the amount of earth and stone required for water control?”

He glanced at the young prince of Jin Kingdom with deep meaning.

At the same time, Yelu Chucai and others also saw the question written by Wan Yankang. (End of chapter)
