The next day, Yang Tianhong still walked into the library pavilion. Pen % fun % Pavilion www.biquge.info

Xiaohe's expression was a little complicated. There is a clear resentment in it, and there is also a bit of joy that is not there.

"I thought you wouldn't come," she said. ”

Yang Tianhong smiled: "I really thought about it last night. But this morning, I suddenly found that I had nowhere to go except for the library and the entire national prison. ”

Xiaohe's black eyes and black skin are mixed together, which has the flavor of the heroine of another world horror movie: "Why?"

Yang Tianhong sighed: "I was born with a situation where I couldn't sit still in the classroom. The teacher would have beckoned me with an iron ruler and a whip, and then he would have stood in the hallway to show me. Either way, it's not what I want. After thinking about it, I can only hide here and survive these few months. ”

Xiao He nodded clearly: "You really have no ambitions." Could it be that you will always only want to stay in the position of General Xuanwu for the rest of your life, and never want to get a high position such as the prime minister and minister?"

According to the Da Chu example, only civil officials can be qualified for such a position.

Yang Tianhong's tone was firm, and he said with a light smile: "What's wrong with General Xuanwu? I would rather kill Rong Di's head in the northern Xinjiang with a million heads than eat a corpse in the court." The high position of Zaizhi may not be related to me for the rest of my life. However, if no one dares to kill the enemy with a sword in this world, how can there be a peaceful and prosperous world?

Xiaohe was dumbfounded by this answer. After a long time, he slowly came back to his senses, frowned, and shook his head again and again: "I really don't know what to say about you." Listening to your words, it seems to make some sense, but according to the concept of the saints, it is simply nonsense. Nonsense. ”

Yang Tianhong still smiled, did not admit it, and did not deny it.

There was a glimmer in Xiao He's dark eyes: "Stay on the first floor, I guess you are still the same as yesterday, I don't think it's interesting." However, if you want to go up to the second floor, you can take a look. You have to promise me one condition first. ”

Yang Tianhong glanced at her: "Let's hear it." ”

Xiaohe turned around and picked up a notebook from the bookshelf behind him and handed it over.

There are only a few sentences on it.

That's a question.

Lei Zhangnai is the general of Zhenxi in this dynasty. Six hundred years ago, in a battle with Rong Di, Lei Zhang led 30,000 light cavalry to attack Luoyingyuan and beheaded more than 5,000 ranks.

In this battle, General Lei's light cavalry went out from the west, traveled 300 miles, turned to the northeast, traveled 120 miles, and then turned to the northwest. Seven hundred and forty miles, then turn north, two hundred miles, turn southeast, go one hundred miles, turn northeast, go six hundred and eighty miles, and finally turn southeast. Entry from Pak Yan Province.

The above formation is the battle of Zhenxi General Lei Zhang for the expansion of the border and the great victory of the land. Q: This battle. How much territory did General Lei expand for this dynasty in total?

Yang Tianhong's expression was a little strange. When I raised my head, I just saw Xiaohe's eyes.

"If you want to go up to the second floor, please solve this problem. ”

Yang Tianhong had a wry smile on his face.

Obviously, Xiaohe is still haunted by yesterday's events. This Nizi couldn't talk about herself in poetry, so she directly found a math problem to make it difficult. I also blamed myself for being emotional yesterday and saying a lot of things that were hidden in my heart on weekdays. Right now. She used it as a weapon against herself.

Since you say that poetry is useless, then let me see how well you have cultivated in arithmetic? Is it possible that you should also devalue arithmetic to nothing?

Taking a deep breath, Yang Tianhong said seriously: "If I solve it, you will let me go up to the second floor?"

Xiao He's black ugly face was full of pride. She stretched out her right little thumb: "Do you want to pull a hook?"

Yang Tianhong nodded, with a serious expression: "Of course." Moreover, it must be stamped with a thumb, and it is absolutely not allowed to repent. ”

Seventeen years old, both are children.

......

Judging by the standards of another world, this is actually a geometric problem.

To the west, to the east, to the northwest, due north......

Doubling down all the mileage numbers and drawing straight lines according to the direction, soon thick black ink appeared on the rice paper, forming an irregular polygonal pattern.

At first glance, it looks like an ignorant naughty boy scribbling on paper.

Xiaohe stood beside him with his hands on his hips, looking at Yang Tianhong who was busy calculating quite proudly.

Lei Zhang was a well-known military general in the State of Chu. Sending troops to the Eagle Plains is also Lei Zhang's successful record. In this battle, of course, the land seized from Rong Di was not so big, and the descendants only made some changes according to the general route of Lei Zhang's troops at that time, and came up with this arithmetic problem.

Arithmetic problems such as chickens and ducks in the same cage also exist in this world. It's just that many Confucian scholars don't like arithmetic, and few people bother with this way.

From the perspective of another world, this arithmetic problem is actually not difficult. The simplest and most direct solution to the problem of finding the area of irregular shapes is to draw auxiliary lines.

Soon, the chaotic and chaotic shapes on the paper were divided by thin black lines, turning into triangles, rectangles, and trapezoids......

As for the length, it is already evident in the title. Three hundred miles to the west, one hundred and twenty miles to the northeast, and so on, are all indispensable heights or side lengths for these segmented figures. Yang Tianhong is very handy in this regard, dividing three by five by two, and listing neat equations in order on scratch paper. Finally, six triangles, two trapezoids, and four rectangles, the total area of which adds up to one thousand four hundred and ninety-three square miles.

Of course, this number can't be completely accurate, it's just that the basic divisor after the decimal place is discarded. After all, there are still many places in this question where the numbers are vague, and without the premise of accurate numbers, Yang Tianhong can only do this.

Looking at the answer that Yang Tianhong wrote on the paper and handed in front of him, Xiaohe was a little confused, and he didn't know what to say for a while. Large black birthmarks obscured her face, making her look like a cute panda standing there with her legs upright.

Yang Tianhong raised his right hand, pointed to the ceiling, and asked in a joking, very friendly, and sarcastic tone: "Now, can I go up?"

Xiaohe nodded subconsciously and held the piece of paper with the answer written on it tightly.

The answer to this question should be between 1,400 and 1,500. Because the numbers in the question are vague, the final number cannot be 100% accurate. In short, as long as it is within this range. Whatever the number is, it's right.

Yang Tianhong floated up the stairs and quickly disappeared between the rows of neatly arranged bookshelves.

Xiaohe touched his forehead in distress, looked at the paper with countless lines, and whispered to himself: "How did he calculate it? Could it be that this guy has heard of this problem before, and he also knows the methods and steps to solve the problem?"

......

There are three floors in the Guozijian Library. The lower two floors are used for books. The top floor is exclusive to Xiang Guang, the king of Changle of the Great Chu State.

It's the last time of the day when the sun stays in the sky.

The afterglow of the setting sun is very comfortable on the body, and the sunlight that shines obliquely from the sky is not dazzling, like a magnificent spotlight, shining on the golden glazed tiles of the library, as if to turn the whole world into the same substance composed of the same color.

Xiang Guang's hair is gray, but his figure is very tall, and his whole person looks strong and powerful. With his hands behind his back, he stood on the terrace on the top floor of the library, smiling. Silently gazing at the brilliant clouds in the distance.

Changle King is a rather interesting title. Of course, Xiang Guang had his own fiefdom, but he took the initiative to ask Emperor Shunming for the title of "Changle", and he was willing to hand over most of the fiefdoms, as well as all the military power. Because of this, Xiang Guang is very different among all the royal families of the Chu State, and he also has many privileges. For example, he can live in the capital for a long time. You can travel in the capital or even anywhere in the Chu Kingdom, but there will not be any secret agents from the imperial court around you.

People are old. It also faded a lot of dreams and ideals from his youth. The dragon chair is far away from oneself, and if you want to sit on it, you must give up a lot of things that ordinary people dream of, and give up the most precious family, friendship, and even love in the world. If Emperor Shunming was a mediocre and incompetent guy, Xiang Guang might still have the idea of wanting to compete for the world. However. No matter how you look at it, his nephew, that is, Emperor Shunming Xiang Zhong, can be regarded as a wise monarch. In that case, it is better to hand over all the power. I stayed in this library by myself, doing my studies honestly, and being a bookworm who buried his head and didn't ask anything outside the window.

If it had been before, Xiang Guang would have sighed at such a beautiful and magnificent sunset, and then made a poem with pride. But now, he couldn't laugh at all, and the most right thing was to regard this landscape as an ordinary natural phenomenon. The years he had experienced in the past reminded him all the time that many things he cherished when he was young were actually meaningless. In the face of eternal time, they are fragile like soap bubbles, which will explode with a "bang" at the slightest touch.

That's life.

The multicolored clouds in the sky faded little by little, and the sky began to become gloomy. Soon, a large area of darkness covered the ground, and as far as the naked eye could see, countless lights gradually lit up.

Human beings have always been able to find a way to fight the darkness and solve problems that they don't like.

Because we're smart.

Xiang Guang, who was wearing a loose robe, turned around, and happened to see Xiao He, who was frowning, sitting on the chair behind him, with his chin in his right hand, looking at the scratch paper on the table that had been drawn by Yang Tianhong with countless auxiliary lines, and was silently fascinated.

Dressed in green clothes, he couldn't hide Xiaohe's curvy figure at all. If you look at it from behind you from a different angle, it will make the man feel an irresistible temptation. But as soon as you turn to the front and see the face shrouded in a large black birthmark, I believe that anyone will be surprised, and then instinctively feel pity or disgust.

Xiang Guang laughed loudly: "Don't look at it, this question has been revised by me, and it is very different from the original prototype." The version you used to test this kid is known only to you and me. Even if he had heard of similar arithmetic problems before, it was impossible for him to know the exact answer. Therefore, he did not pretend, but relied on his real talent and learning to solve the number of 1,493 li. ”

Now that he has given up competing for the world, Xiang Guang must find something that interests him and is addicted to it. He has been fond of arithmetic since he was a child, and he is willing to stay in this library. Guozijian is the place where literati and artists are most concentrated, and Xiang Guang did not reveal his identity, and was willing to manage the library here. Over time, this place has become the royal library of Da Chu.

Xiaohe's gaze never left the scratch paper: "I have never seen this kind of problem solving, but there is no doubt that it is really clever." ”

"It's not just clever!"

Xiang Guang pursed his lips, smoothed the white beard on his lips with his thumb, and said with emotion: "I have searched through the classics of my predecessors, and I have not found any clues about this solution. This should be Yang Tianhong's own originality. Or. There is a certain arithmetic master in the Guiyuan Sect. One thousand four hundred and ninety-three...... This number is very accurate, but even I, the author of the question, could not calculate it the same way as before. It is in response to that sentence: The back waves of the Yangtze River push the front waves!"

Xiaohe smiled slightly: "Uncle Wang, you are too humble. Even if you look at the countries in the world, you can still rank in the top three. ”

"Hmph! Even if you are a master of arithmetic. Another piece of!"

Xiang Guang, the king of Changle, snorted nonchalantly, walked to the nearest chair and sat down, turned sideways, looked at the manuscript paper placed on the coffee table, and said seriously: "The Yang family has been loyal and good for generations, and Guangping Hou has always been talented. What Yang Tianhong said does have some truth. My Da Chu's method of controlling martial arts with literature is really flawed. If we despise the warriors, how can we come to fight against the soldiers of the world? Is it really necessary to send civil officials and ministers to battle with books in their hands in the future? When they saw the enemy, they called "Zhihu also", and they dismounted and knelt down one after another, and came to surrender one after another?"

Xiaohe laughed out loud: "Uncle Wang, you are so interesting." How did you suddenly come up with this?"

"I don't want to, I can't!"

Xiang Guang's tall body leaned back, tilted his head, stared at the starry night sky that vaguely appeared outside the balcony, and said lightly: "Except for the generals who followed Taizu to open the country. The hussar general Yang Jing should be the most heroic and handsome man in my Great Chu. In the twenty years of Rongdi in Beiding, Rongdi was killed. Frightened. If there was no Yang Jing in the north, my Da Chu would have been disturbed by Rong Di and would have been in chaos. It's ridiculous that those Wenchen who are vegetarian corpses in the court actually said that Yang Jing killed too much, which made the heavens angry and resentful. According to the king's will, the whole family of these bastards should be banished to the north or south of the country, and let them experience it for themselves. What kind of results will you get if you talk to the barbarians with a scroll in hand?"

Xiaohe's eyes flashed with curiosity: "Uncle Wang, listening to your tone, it seems that you appreciate Yang Tianhong very much?"

"What is more than appreciation, these words of this boy are very appetizing to this king. ”

Xiang Guang, the king of Changle, slowly stroked the long beard on his chest. His eyes lowered, and he saw the lights in the back room of the Guozijian in the distance, and his tone was a little gloomy: "Don't talk about it from afar, just talk about this Guozijian." The people who are qualified to enter here, except for the descendants of wealthy officials who spend money to buy a student status, are poor students who have passed the state and county examinations. These people have no problem learning to write and write poems, and their articles are also full of flowers. However, what is the significance of merely writing essays and poems? Take what Yang Tianhong said as an example: If the champion who won the first place in the palace examination in the Bagu article is put on the local level, will he be able to measure the land? Do he know how to manage water conservancy? How to deal with the hungry people in a disaster year? How can he ensure that the grain prices of the people are not manipulated by businessmen in a good year, resulting in cheap grain and hurting the peasants?

Xiao He's bright black eyes flashed and asked, "Uncle Wang, what you said is true?"

"All of them!"

Xiang Guang obviously lost his temper, and said angrily: "Gao Yufang, the commander of Sangmo County, is the eye of Guangrun's 27-year imperial examination. This person's articles and poems were once rated as unparalleled in the world by the first emperor. However, Gao Yufang won't even fart on the ground. After taking office, Sangmo County was a mess by him, and he couldn't even collect the tax money. This person can be described as extremely incompetent when it comes to management. Sang Mo was originally a first-class rich county, but he made it into a poor county with poor harvests year after year. In the end, the people of Sang Mo rebelled, and Gao Yufang was killed by the mob. The human head was hung on a flagpole in front of the county office, and the body was chopped up by the mob and fed to the dogs. The depth of the people's grievances can be seen. ”

Also, Lu Jinsheng, the commander of Yaoding County, is also good at poetry and writing, but he doesn't even understand the most basic administrative affairs. This person has served as the county magistrate in Yaoding for six years, and has never been out of the county office, and he either writes poems and paintings every day, or accompanies his wife and beautiful relatives to drink and have fun. All affairs are handed over to the county to handle, and the people below are deceived and concealed. In the end, the people of Yaoding County didn't know that there was a county order above, and they only knew that the county's affairs were all in charge of the county. There is such a guy who is stupider than a pig, do you think it is my great Chu Zhifu and an example for students in the world?"

In contrast, Yang Tianhong's words were simply thought-provoking. It's a pity that there are very few people in the Manchu Dynasty who can see the problems behind it. Even if there is, it is far from being the opponent of countless literati in the world. Like this king, I am not used to the filthy ways of the so-called scribe leaders. Isn't it just that he can write a few poems and write a few beautiful words, and he will his tail to the sky one by one. If it really encounters an invasion of foreign enemies, Da Chu needs strong men to set a side against the enemy, you see how far they must be hiding and hiding one by one, which is worse than rats and cockroaches. ”

Xiaohe's eyes were as bright as the morning star, and he asked slowly: "Uncle Wang, do you mean that poetry is useless?"

"Of course not. ”

Xiang Guang said seriously: "No matter what you do in this world, you must have a degree. This is true of the poems, and the same is true of the soldiers. Your father is very good in this regard, otherwise, he would not have allowed Yang Tianhong to resign from the title and leave him with an official position in the court in advance. It's just that if you want to change the status quo, it won't happen overnight. But as long as there is a benchmark and start like Yang Tianhong, those stupid-minded old bastards in the DPRK will also have opponents. (To be continued.) )
