"That's it?" Shen Xuan snorted and disagreed: "Isn't it just a hook with three strands, four strings and five?" What's the big deal. ”

"You know that, too?" Sun Shao was a little surprised.

"Who doesn't know?" Shen Xuan smiled a little proudly: "Nine chapters of arithmetic, Zhou Ji arithmetic, I know a little bit about it." ”

Look at you. Sun Shao straightened up, very angry at Shen Xuan's disdain, he thought for a moment: "You only know the hook three strands, four strings and five, but you know that if you hook three strands and eight, what are the strings?" ”

Shen Xuan rolled his eyes for a while, and then said, "Eight should be slightly stronger, and nine is slightly weaker." ”

"Then why?" Sun Shao asked, "Why is this happening?" ”

"There's no reason for that, because that's the way it is." Shen Xuan was a little tricky. He is good at literature, history and the art of war, and arithmetic is not his strong point.

"So you don't know why." Sun Shao pursed his lips, took a piece of paper again, drew a diagram on the case to prove the Pythagorean theorem, and was about to speak, but Shen Xuan stopped him: "Wait, general, this diagram ...... Is it from this book? ”

"It's not." Sun Shao saw Shen Xuan's strange face, and he was also a little surprised: "What, have you seen this picture?" ”

"I think I've seen it." Shen Xuan tapped lightly on the bookcase, staring and thinking: "You let me think about it, I must have seen this picture somewhere, someone should have told me, I just can't remember it for a while." ”

Sun Shao didn't dare to interrupt his train of thought. He knew that the proof of the Pythagorean theorem was a major event in the history of mathematics, just like pi, and that it was nothing to look at as a matter of precision, but in the history of mathematics, or in the history of science, this step often represents an era. He only vaguely remembered that the Pythagorean theorem was first proved by the Chinese, but who proved it, he didn't know, looking at Shen Xuan like this, could it be that someone had already proved it at this time?

"I've heard people say this, but I can't remember who it is." Shen Xuan smiled bitterly, "This...... Is it important? ”

"It's important." Sun Shao took the pen, since Shen Xuan said that someone had proved this, there was no need for him to demonstrate it to Shen Xuan again. He said solemnly: "Do you know why Bu Qi lost his troops this time? ”

Where did Shen Xuan know, he only knew that Bu Qi had lost the battle, if it wasn't for the victory of Sun Shao and Wei Jing to make up for his losses, he would have written to ask for his guilt now. But he knew that since Sun Shao mentioned this matter at this time, it must have something to do with this Pythagorean.

"There are many reasons why Buqi lost the battle, but one of the main reasons is that there is a problem with the chart in his hand." Sun Shao briefly described the battle in Jiaozhou, and then said: "If you want to suppress pirates, you must be aware of where the pirates are, and you must measure them in advance." Nautical charts are no different from land maps, and if they are wrong, they can be fatal, so this principle should be used when surveying. ”

"I know this, and I used this when I used to measure acres." Shen Xuan said: "It's just that everyone is using it, but no one has asked why." These are all the learning of craftsmen, and not many people have learned them, and most of them are just learning about them. ”

"But this one works." Sun Shao sneered: "To put it mildly, you all think that Dong Zhongshu is a saint, but in my opinion, his merits are far inferior to Zhao Guo." ”

The corners of Shen Xuan's mouth twitched, and he was not interested in arguing with Sun Shao about this topic. In his opinion, this is simply nonsense and not worth debating. Seeing him like that, Sun Shao was not interested in discussing with him, so he continued: "The biggest problem encountered now is how to measure the direction and distance of the island and draw accurate charts. ”

Shen Xuan stretched out a finger and scratched his eyebrows: "I know that there was a method before, called the Heavy Difference Technique, which is a method that must be used when measuring the map. However, this kind of technology can only be understood by those who specialize in surveying and mapping, and it seems to have been lost later. ”

Sun Shao sighed. The Han Dynasty in the Western Han Dynasty has a very good ability to map and map, Mawangdui unearthed maps can prove, but unfortunately such ability did not continue to develop, to the early years of the Western Jin Dynasty, there is a cartographic expert named Pei Xiu in a very disdainful tone said that the maps of the Han Dynasty are garbage, not worth mentioning. Sun Shao believed that he should not have seen the maps hidden in Mawangdui, otherwise he would not have said so. However, this also illustrates a problem, in the four hundred years of the Han Dynasty, the inheritance of technology is far less stable than the inheritance of scriptures, not only not to mention rapid development, but even regression.

Xianzhou Island, a hidden harbor, dozens of boats gathered together, dozens of men gathered together, some people wore well-cut brocade clothes, elegant demeanor, some wore short beats, exposed their chests, some people casually put on a dress, some simply only had a cow nose robe, they looked like they had their own characteristics, some were refreshing, and some were thicker, but their expressions were very consistent, all with gloomy faces, looking at Su Thick legs squatting on the boulder and not breathing.

Su didn't speak, he held a white stone in his hand, rubbed his fingers on it, and his two big eyes drooped, as if he was asleep. Several of his subordinates stood horizontally, their vigilant eyes roaming over the faces of the dozens of men, their big rough hands gripping the hilt of the ring-headed knife, and from time to time loosening their fingers that were numb because they were too tightly gripped. Today's atmosphere is so tense that they have to be careful to deal with it, and a moment of laxity can bring death.

These dozens of men are all leaders or representatives of large and small pirates in the East China Sea, and they are here to negotiate with Su Thick Legs. These people, most of them have 100 ships, 4500 people, less than a dozen ships, 100 people, and the strength is stronger than Su Thick Legs, but Su Thick Legs' subordinates have many elites who have gone through big battles, and their overall combat effectiveness far exceeds that of any other people, so he is a well-deserved boss in the East China Sea. Usually these people don't dare to compete with him face to face, but today's situation is a bit special: everyone has made an appointment to talk to Su Thick Legs.

There is only one reason, the merchant fleet that has just sailed from Jiaozhou.

The East China Sea is not better than the South China Sea, and the merchants from all over the country go beyond the South China Sea, and they are divided into several routes, some go directly into Yizhou, some enter Jingzhou, even if they go to Yangzhou, they are also divided into two roads, all the way by land, through the area of Da Yuling into Yuzhang County, all the way from the sea. Therefore, the pirate business in the East China Sea is far less good than that of the pirates in the South China Sea, and there have never been pirates of the scale of the South China Sea in the East China Sea, not even like the headhunter, not for no reason, because the business in the East China Sea is limited and cannot support such a large number of pirates.

More than 300 merchant ships, for the pirates of the East China Sea, are a piece of fat that they never dared to imagine before, enough to make any pirate excited, and the huge wealth temptation makes it rare for them to get together and negotiate with Su Thick Legs.

The reason for this is also very simple, there is a Sun Shao in the merchant ship, and Sun Shao has a pirate flag with thick legs in his hand. When he went south a few months ago, he was flying the pirate flag of Su Thick Legs all the way through the market, and the pirates in the East China Sea didn't touch that business for the sake of Su Thick Legs. But now this piece of fat is too big, and no one can let them pass like this calmly.

Su's thick legs have to be given, but his face is not worth the value of these more than 300 boats.

There is only one opinion from everyone: please be considerate of Su Dangjia, and the brothers should also live.

Su Thick Legs has been a pirate for so many years, and it is the first time that he has been called by so many pirates in person. Even when he first arrived in the East China Sea, he fought with other pirates, and he had never seen such a big battle, this time, the pirates with heads and faces in the East China Sea came, if he really wanted to fight, no matter how his men could fight, it would be impossible to win so many people.

Su Bush's subordinates also complained a little, even if they let Sun Shao go last time, it was more or less to give Guan Yu a little face, but what kind of pirate flag did you give, isn't this a violation of professional ethics? Now, not only can you not do it, but you also block other people's financial paths. If you don't agree, you may start fighting immediately, and if you agree, then your face will be over, and they will taste the sweetness of unity in the future, and they will definitely continue to do this again.

Su Thick Legs was also very embarrassed, he didn't regret the matter of the pirate flag, he felt that Sun Shao had given him a big problem, you have my battle flag, you are safe, why do you have to be involved with so many people? Isn't that a provocation target?

"Boss." Seeing that Su was thick and didn't speak, the military advisor Wei Ping knew that he was embarrassed, but it was not a thing to drag it out like this, did he want to leave these people for dinner?

"So be it." Su Thick Legs raised his head and glanced at everyone: "Thank you for looking up to me, come and report to me." However, General Guan is my old master, and I can't ignore morality, so I won't participate in this trip, and if you want to go fishing, I won't stop you, after all, this is everyone's livelihood. There is only one reluctant request for thick legs, and I also ask you to give me some face. ”

Everyone was relieved when they saw him, and they also secretly breathed a sigh of relief, they all knew the strength of Su Thick Legs, if they really wanted to fight, of course they could win, but there would definitely be a lot of losses like that, and it would be best if they could solve it peacefully.

"Please ask General Su to say it in person, as long as it doesn't hinder our lives, it's easy to say." A long-faced man in a brocade robe said politely. His name is Zhou Qun, a native of Lujiang, nicknamed Mingjiang Dragon, who is second only to Su Thick Leg in this group of pirates, with more than 80 ships and nearly 400 households. is insidious and quite scheming, and this cooperation is also led by him. He is very happy now, this time he can suppress Su Thick Legs, and take everyone to make a windfall, his prestige will increase rapidly, and it is a matter of course to overpower Su Thick Legs.

Su glanced at him, crooked his mouth, and laughed: "More than three hundred boats, enough for you to eat, right?" ”

Zhou Qunpi nodded with a smile: "It's enough, if this business wasn't too big, the brothers wouldn't make it difficult for the general." ”

"Thick legs appreciate it." Su Thick Legs put away the white stone, raised his head to look at the others, and arched his hand: "There are more than three hundred boats, and you must not be short of one or twenty." General Sun's twenty boats, even if I am a member of Su with thick legs, please give some face. I'm determined not to touch the rest, how? ”

Zhou Qun glanced back at the others, who looked at each other and had no opinion. With the strength of Su's thick legs, he wants to monopolize these twenty boats, and others dare not have any opinions. Since he himself is willing to give up this business, others are not reluctant. They all nodded at Zhou Qun, and subconsciously regarded Zhou Qun as the new boss. Zhou Qun was very satisfied, and smiled politely: "General Su's righteousness, we admire it very much, I will assure General Su that those twenty boats are absolutely unharmed." ”

"Thank you." Su Thick Legs nodded.

"However," Zhou Qun's tone changed, and he said very solemnly: "There is a sentence, it is better for us to make it clear to the general in person." ”

Su Bu's legs were a little unhappy, his face sank, and he looked directly at Zhou Qun. Zhou Qun's eyes flashed, and he instinctively wanted to avoid it, but then he held it again. He forced a calm arch of his hand: "Presumably, the generals also know that General Sun has hundreds of officers and soldiers under him, and he is the strongest among these people. We can listen to the general and not provoke him, but if he wants to be strong, not to protect the merchant ships, then ...... But you can't blame us. We can't just be beaten and not fight back, General Su, do you think that's the truth? ”

Su Thick Leg hesitated for a moment, and his face changed: "You dare to touch my Su Thick Legs' business?" ”

"Not really." Zhou Qun met Su's fierce gaze and protested: "If General Su can ensure that he doesn't cause trouble, we will definitely not touch him, but if he wants to attack us, then we can't just be beaten, right?" Otherwise, please General Su go out and lead us to this fishing trip, and when the time comes, you stop him, and we will be responsible for the rest. ”

Su Bush was stunned, Zhou Qun's words were very realistic, and the reason was not excessive, if Sun Shao made a move, he would not let Zhou Qun and them fight back. However, let him go out to deal with Sun Shao, no matter what form it takes, it doesn't seem to be suitable, he can not give Sun Shao's face, but Guan Feng is on the boat, he can't deal with Guan Feng.

Zhou Qun saw that he had the upper hand, and he refused to give in even more, and motioned for everyone to talk together. Everyone saw that Su Thick Leg was not angry, and his courage also grew, and he expressed his support for Zhou Qun in a gossipy manner, Su Thick Leg was a little unexpected, he wanted to get angry but felt that he was at a loss, he thought about it for a long time, and had to wave his hand: "I will send someone to inform General Sun and ask him not to come forward, so it's okay, right?" ”

"Yes, yes." Zhou Qun said in a strange manner: "However, the people you sent must set off with us, if we go in advance, then what kind of fishing are we going to do?" ”

Su Thick Legs choked again, he looked at Zhou Qun, who was a little carried away, and was helpless, so he had to grit his teeth and nodded: "Okay, I will set off with you, and I hope that you will abide by what you just said, otherwise, don't blame me Su Thick Legs turned his face." ”

"Don't worry, general, as long as he doesn't cause trouble, we will never move him." Zhou Qun emphasized his words again, turned to the crowd and raised his hand, signaling them to be quiet, that posture seemed to be the boss of the pirates.

Su was furious, but helpless. The cronie behind him, Heiyu, gave him a worried look, licked his lips, and turned his fierce gaze around the back of Zhou Qun's neck. Zhou Qun's heart palpitated, and he said a few words calmly, not daring to stay longer, and hurriedly left with everyone.

"General, this ......" After the figures of Zhou Qun and the others disappeared, the black fish whispered: "We really ......"

"To be a man is to be righteous." Su Thick Leg snorted, interrupted Heiyu's words, and said undoubtedly: "General Guan was so kind to us back then, we can't harm Miss's surname." You don't need to say it anymore, if you are unwilling, follow them now, I won't stop you, but if you hurt Miss's surname, I will chase you to the edge of the sky, and I will have to cut you. ”

The black fish blushed: "General, how could I leave you?" ”

"That's good." Su glanced sideways, sat down again, took out a white stone and rubbed it, and his eyes were full of fierce light: "This bastard river is not small, you want to be the boss of the East China Sea?" Dare to get entangled and shout to Lao Tzu, hum, don't give him some benefits and take a look, he doesn't know how many catties and taels he weighs. ”

"General, if they make a fortune this time, I'm afraid we may not be able to suppress them." Wei Ping reminded: "His strength is not bad in the first place, and the harvest this time will definitely not be small, and with the help of those people, we are not opponents at all." ”

"Damn, it's really troublesome." Su Bu Leg frowned thickly, and pinched his eyebrows in embarrassment: "I hope Sun Shao won't be too numb, and save some face for Lao Tzu's flag, otherwise, this time it will be planted." ”

Wei Ping rolled his eyes: "Mixed River Dragon, they gathered nearly a thousand boats, more than two or three people, the momentum is so big, although General Sun has two building boats, but he connected the building ships together, his ability to act was greatly affected, and he couldn't deal with them at all, so he shouldn't be able to make a move without his strength." I'm worried about the mixed river dragon, I heard that General Sun's eighteen boats are all big ships, compared to others, this is enough to be worth forty or fifty boats, they ...... Are you willing to let it go? ”

"He dares." Su Bush's eyes glared: "If he dares not to put me in his eyes, I will definitely not spare him." ”

Heiyu smiled bitterly, wanted to say something, and shook his head again, he always felt that Zhou Qun had just set a trap on Su Rou's legs, and when they appeared, how could Sun Shao not make a move? Even if he shot an arrow, Zhou Qun could be said to be Sun Shao's hand first, and then rushed up and grabbed it. Even if Sun Shao really didn't do it, Zhou Qun just grabbed it, who can say clearly? Su Thick Leg must have been planted this time, not only wasting a chance to make a fortune in vain, but also standing on the opposite side of all the pirates.

"Alas, to put it mildly, Miss's life is really good." Su slapped his thigh: "General Sun is really interesting, for her, he actually connected the building boats together, but ...... It's not good for war. He thought for a moment, turned his head and said, "Let the brothers gather, and we will go too." ”

"Go too?" Blackfish's eyes lit up.

Su Thick Leg glanced at him, and raised his leg is kick: "What do you want?" Lao Tzu is going to watch the battle, don't let the vertical son of the mixed river dragon deceive Lao Tzu. ”
