"Then let me ask you again, how to arrange the nine numbers from one to nine in three columns, regardless of the vertical and horizontal oblique angles, every three words add up to fifteen?" asked the county lord of Changsi. Li Changsheng thought to himself: "This is the oldest method of the Nine Palaces in the ancient "Nine Chapters of Arithmetic", it is widely spread, and the smarter elementary school students can easily solve it, is it a problem when they get here?"

It's no wonder that the Book Sword Continent is based on cultivating the Book Sword, and what is cultivated is cultivation and killing techniques. There's really no use for arithmetic like this, so it's basically a blank slate here.

At the moment, he said: "The righteousness of the nine palaces, the law is based on the spirit turtle, two or four is the shoulder, six or eight is the foot, three on the left and seven on the right, wearing nine shoes and one, and five in the center ......" This song has long been passed down in the world, and Li Changsheng can finally say some proper nouns. As soon as these proper nouns came out, everyone felt that Li Changsheng was simply an arithmetic master and had a very high cultivation in mathematics.

Li Changsheng said: "Not only the Nine Palaces, but even the four or four pictures, the five or five pictures, have long been circulated in the Han Dynasty. Let's just say that the four or four pictures are arranged in four rows in order with sixteen characters, first with four corners for one, one for sixteen, four for thirteen, and then within the four corners for one, six for eleven, seven for ten. The combination of the horizontal and upper and lower oblique angles is thirty-four. ”

After listening to Li Changsheng's words, the official who received the envoy nodded secretly, feeling that Li Changsheng was quite knowledgeable. Everyone knows that mathematics is almost a blank in the Han Dynasty, and they don't know anything about the nine palaces and four fours. He said that it was widely spread in Dahan, and that was to promote the prestige of our country.

And the more the county lord of Changsi listened, the more pale his face became, and he said in his heart: "I originally thought that these algorithms were my own creation, but I didn't know that they had long been widely spread in the Han Dynasty, and it seems that the small Mo Yue Kingdom is really not as good as the civilized country like the Great Han." Said: "Little woman, the frog at the bottom of the well." Let the people of Shangbang laugh, Your Excellency's numeracy is ten times better than mine. I threw in the towel. After saying that, he retreated.

Hearing that Li Changsheng easily solved her problem, the next few words earned enough face for the big man. Emperor Wu couldn't help but smile and nodded in approval. If he hadn't stood up, I'm afraid Dahan would have lost face today. At the same time, I also had some doubts in my heart, Li Changsheng was famous for his talent in poetry, when did he have such an in-depth study in mathematics? Among the eight princes of the Han Dynasty, he was indeed the Hidden Dragon and Crouching Tiger, all of them were great geniuses, and it was not for nothing that the eldest son ranked third among the eight princes and second only to the two princes. Although the calligraphy cultivation of the two princes is very strong, they are not as good as Li Changsheng in other aspects.

"Dare to ask who is the surname of this prince, and what is the ranking among the eight princes?" Seeing that the county lord of Changsi admitted defeat and retreated. The eldest prince Mole stood up and asked him with a folding fan in his hand. He also has some understanding of the Great Han and knows how difficult it is to obtain the name of the Eight Great Princes. This person's cultivation is among the best among the talents of the Han Dynasty, but he has such a study in mathematics, and his talent is really terrifying.

"In Xia Li Changsheng, he ranked third among the eight princes, and was given the title of Changsheng Son. Li Changsheng replied.

"Ranked third?" Prince Mole looked at him, ranking third is so good, so what about the first and second, isn't it even more terrifying?

"The first-ranked Heavenly Prince has already been ordered to go to the southern coast to exterminate the thieves. The second Feile Gongzi is ordered to Cangzhou for disaster relief, and the two sons can deter barbarians on the outside, and they can stabilize the country on the inside. As for the reception of envoys from small countries, it is enough to do so. Li Changsheng said: "As for His Majesty Emperor Wu, I have arranged for me, the third-ranked receptionist. Or for the sake of Mo Yueguo's face as my Han vassal country. ”

Li Changsheng's words made all the Han courtiers nod their heads, as a Han man, he raised his country's prestige everywhere in front of foreign envoys. His bearing and insight are truly impressive. Even if such a person represents the Han Dynasty and goes to the enemy country, he is definitely not a loss of national dignity.

"Hmph!" the eldest prince snorted coldly. "I have long studied mathematics at my time, so it is not surprising that I can solve my imperial sister's problem. If you don't know how to solve my second problem?"

"A person's energy is limited, and it is impossible to be proficient in all aspects. You have now changed someone, and if you can't solve it, my big man will have a genius who can solve it. Li Changsheng said: "But it's still Your Majesty's words, if you have any problems, you can raise them first, so that everyone can refer to them in detail." ”

He did not say this to find a way out for himself, but he was telling the truth. The problem raised by Mo Yueguo was screened out by the entire country, and Li Changsheng could not say that he was sure that he would be able to solve it. One person's abilities are limited and it is impossible to study to the top in all aspects. Just like Li Changsheng himself, he knew something about the Seven Great Academies in his knowledge, but he only decided to specialize in military supernatural powers.

After listening to Li Changsheng's words, the Prince of Magic Music was noncommittal and said, "What is the question I want to come up with...... Come on, move up!" As soon as the words fell, I saw several shirtless Mo Yueguo men carrying a huge log to the front of the big tent, and with a "boom" sound, Mo Yueguo put the wood on the ground.

"This is a hundred-year-old giant tree, who of you can guess which side of it is the head and which side is the tail? I know that there are several saints in the Seven Great Academies of the Han Dynasty, and they can know the world. However, to identify this head and tail, you can't use the abilities of any scholar saint, you have to use a simple method. The eldest prince said triumphantly.

Hearing this difficult question from the Prince of Magic, the courtiers of the Great Han frowned. This piece of wood is taken from a small section in the middle of a century-old giant tree, and it is impossible to distinguish the two sections from the degree of thickness. And its surface is unusually smooth, and the two sections look exactly the same.

Among the Han people present to receive the envoys, Emperor Wu is already in the realm of a saint. If he used the ability to know the world, he could easily know it. But the eldest prince said it first, and if Emperor Wu came forward to solve it, it would be an insult to the country's prestige.

How should we judge this? Some of the old ministers of the big men frowned. His eyes were fixed on the wood, trying to find the difference between the two ends. I have some thoughts in my heart but I don't dare to draw conclusions easily, the difference between the two ends is too small, and I really don't dare to draw conclusions easily. And judging from this aspect, it is not enough to convince the public.

"This matter is extremely easy!" At this time, Guo Jie, the sword boy, stood up and said: "I have traveled to rivers, seas and lakes and met some fishermen. Trees, by the aura of heaven and earth for a long time, put into the lake heavy for the head, please for the tail. Just put this piece of wood in the lake, and the head and tail will be decided!"
