Prince of Song Dynasty

Chapter 24 Comparing Mathematics
Under the dumbstruck eyes of the group of leaders and the soldier who took him to eat, Ye Chen ate enough food for seven people before he was completely full.

Then, a soldier named Li Hu brought Ye Chen to a camp of Cao Bin's soldiers, and found a suit of soldiers' uniforms that fit him well.

I don't know if it's because he witnessed all kinds of miraculous phenomena on Ye Chen, Li Hu, a veteran who has killed countless people, has a faint instinctive fear of Ye Chen.

After thinking for a while, Ye Chen vaguely understood what Cao Bin meant, that he wanted to keep himself in the Great Song Army and serve the Great Song.

In fact, Ye Chen also wanted to embrace Da Song's thigh at this time and be protected by him.Because after eating and meditating calmly just now, he thought of Yu Daoxiang, Si Luoyi and Guo Wuwei, and the forces behind the three of them, for the pendant on his neck, which is the Heavenly Star Jade Pendant that those three people called imperative attitude.

So, he has been feeling extremely uneasy.He knew that even if he handed over the celestial star jade pendant, he would inevitably end up being killed.

And under the coveting and even hunting down of the forces represented by these three people, if they can survive, I am afraid that the two behemoths of the Northern Song Dynasty and Daliao have this strength.For Ye Chen, the best destination is naturally to be under the protection of Song Dynasty, and the most direct and effective choice is to join the army.With the threat of a large army, it would be difficult for Yu Daoxiang, Tianyi and Taiping sect's demons to attack him.

Maybe Cao Bin has seen through his current situation, so he wants to keep him.

Because of this idea, Ye Chen chatted with Li Hu, and at the same time learned about the situation of the Great Song Dynasty and the affairs of the Great Song Army from him.In order to let yourself quickly familiarize yourself with the environment you are in.

Cao Bin returned to Beiying, summoned all the commanders and generals under his command, and after arranging the matters Zhao Kuangyin said during the discussion, he ordered people to bring Ye Chen over.

In the handsome tent, Cao Bin looked at Ye Chen and said without any nonsense, "Ye Chen! Do you know that you have been in a coma for more than ten days, and you haven't eaten a bite of food, or even a drop of water, but now you look radiant." Rejuvenated, refreshed, how do you explain that?"

Ye Chen was taken aback when he heard the words, he thought he would be unconscious for at most a day or two, but he thought it would be more than ten days.Li Hu didn't mention this matter just now.

Ye Chen smiled wryly in his heart, thinking that it seemed inevitable that he would lie again.

He had a lot of thoughts, and said bravely: "When Yu Daoxiang, Si Luoyi and Guo Wuwei were fighting for the treasure, I took the opportunity to escape, but I was already seriously injured at that time. After I ran to the Yellow River in one breath, Feeling that he was about to pass out, he swallowed the healing elixir given by his master, as well as another pill called Bigu Dan. The injury on his body has improved now, and it is because of the magical effect of the healing elixir that he was able to survive for more than ten days. Eating, not drinking water, but not starving to death, it is because this Bigu Pill is extremely miraculous, as long as one swallows one pill, one will not be hungry for half a month."

Cao Bin's eyes brightened, and he said: "There is such a pill in the world. Your master is indeed an unborn expert. Hmm... Do you still have this bigu pill on your body now? Let me show it to you."

Seeing that Cao Bin didn't seem to have any doubts about what he said, Ye Chen breathed a sigh of relief, and said, "Commander! Both the Bigu Pill and the Healing Pill have been used up, and I don't have any pills on me now."

Cao Bin was a little disappointed, and said, "Then you can learn alchemy from your master? Can this kind of bigu pill and other pills be refined?"

Ye Chen secretly screamed in his heart that something was wrong, and pretended to be embarrassed and said: "I don't have the qualifications for alchemy, so I failed to learn alchemy from my master."

The expression on Cao Bin's face was even more disappointed, and he said in a deep voice: "Your master is such a tall man, a fairy-like figure, and you are at least 20 years old. You have been with your master for so long, what have you learned? Tell me Listen to me handsome."

Ye Chen groaned secretly in his heart, suddenly his heart moved, organized his words in his mind, and said cautiously: "General! I learned mathematics, physics, chemistry, biology, map drawing, history, geography and other academic knowledge from the master."

Cao Bin frowned slightly, and said, "I know history and geography. This mathematics sounds like arithmetic. What is this physics, chemistry, biology, and map drawing?"

Sweat was already appearing on Ye Chen's forehead. He knew that if he didn't answer well at this time, his previous lies about his identity might be exposed. Although he wouldn't lose his life because of this, if he didn't handle this matter well, he would join the army. Ordinary matters of shelter go a long way.

After pondering for a while, Ye Chen said, "General! Mathematics and arithmetic are indeed similar. As for physics, chemistry and biology, they can be regarded as the study of things."

The disappointment in Cao Bin's expression was undisguised, and Ye Chen thumped in his heart, thinking of the theories of governing the country and the world, such as Confucianism and Huang Laozhi in Chinese feudal society, or some methods of governing the army, for some practical physics, chemistry, etc. They are extremely underestimated together with biological equivalents, and most of them are even reduced to low-level. It seems that only arithmetic is quite respected.

Sure enough, Cao Bin didn't mention Gewu at all, and maybe he remembered the strange things that happened to Ye Chen, especially the magic of the medicine mentioned, and respect for the master Ye Chen said, so he held the last little expectation , Said: "Since you have studied arithmetic, this commander will call some comrades in the army to exchange and compete with you to see how far you have learned? Come on! Go and invite Mr. Jia and the other two disciples to come over." this."

The three soldiers next to him took orders and quickly left the camp.

Seeing that Cao Bin wanted to test himself, Ye Chen breathed a sigh of relief. He thought that in the Song Dynasty, when elementary school students such as the three-fold well, chickens and rabbits in the same cage, and Han Xin's command of soldiers were super difficult, Ye Chen didn't believe that there were any problems that could pass the test. Own.

Not long after, three scribes walked in from outside the tent. They were an old man in his fifties and a half, and two middle-aged men.

The three of them may have learned from the soldiers that they wanted to learn arithmetic by comparing with others. After saluting Cao Bin, they clasped their hands when they saw how young Ye Chen was, and their faces were full of arrogance. But they have to compete with a young boy who is still young. If it is not for Cao Bin's face, they would have free time to play with this young boy.

Cao Bin was quite polite to the three of them, especially to the leading man in his fifties, who was extremely respectful.

"The three gentlemen, please have a competition with Ye Chen in arithmetic. As for how to compare, let's ask each other! Let's see who can beat who first." Cao Bin spoke and acted vigorously, rarely talking nonsense, and said straight to the point.

The three scribes nodded, did not speak, just looked at Ye Chen and snorted coldly.

Ye Chen looked calm and nodded in agreement.

Ye Chen knew that Cao Bin had doubts about the origin of his identity that he said before, and this math competition in front of him may be his only chance to prove that he is a master of the outside world, so how dare he neglect it? On the way where the famous praise came, he had already thought hard and thought about the countermeasures, thinking not only to win, but also to win a high profile, so that people would know at a glance that the three famous praises were like clouds and mud compared to him in mathematics. do not.

Therefore, Ye Chen coughed dryly, and while the three disciples were discussing with each other in low voices, he said loudly: "Since the three adults are proficient in arithmetic, how can binary be known? Can Chen Zi measure the sun? ? Can Zhao Shuang's String Diagram be solved?"

The three scribes were startled when they heard the words, and then looked at Ye Chen incredulously. Among them, the half-aged old man tremblingly said: "Binary is the essence of my Chinese mathematics. How can I not know it. It is said that Chen Zi's method of measuring the sun is from "Zhou Zhou" Bi Suan Jing", but this book has been lost for many years, and no one today knows Chen Zi's method of measuring the sun. As for the double difference method, it is the pioneer of the Pythagorean measurement method. Three strands, four mysteries and five, the old man naturally knows. It's just that Zhao Shuangxuan's picture is a picture of fortune, how can it be unraveled by mortals."

"Hahaha...Since you know the Pythagorean measuring method, why don't you know Chen Zi's solar measuring method, but you don't know that Chen Zi's solar measuring method is a breakthrough application of the Pythagorean measuring method. The kid re-deduced it, and it's just half a stick of kung fu." Ye Chen let out a long laugh, his face full of disdain, and then he said: "As for the little Mr. Zhao Shuangxuantu who thinks it is a picture of fortune, how ridiculous. Open your mouth and untie it."

"Don't talk too much, kid, I don't believe you can unlock Zhao Shuangxuan's picture."

"Listen up, three gentlemen, and treat it as a small contribution to my Da Song arithmetic. If you don't remember it, let me explain it again later, and I will give you the gift of master and apprentice." Ye Chen Ye Chen seemed to have changed Personally, said arrogantly but calmly.

After finishing speaking, regardless of the changes in everyone's faces, he said: "Pythagorean stocks are multiplied separately, and they are combined into Xuanshi. If you divide them, it is Xuan. If there is a Xuantu, you can multiply the Pythagorean shares together to form Zhu Shi Er, and double it to form Zhu Shi Si." Multiplying the difference of Pythagorean stock is the middle yellow real. Adding the real difference also becomes the mysterious real. Using the difference to subtract the mysterious real, half of the rest. Taking the difference as the method, and dividing it by the formula, you can get the hook again. Adding the difference to The hook is the stock. Wherever the reality of the Pythagorean is combined, it becomes the mysterious reality. Either the moment is inside, or the square is outside. And it is extended. And the real side of the stock. The reality of reducing the moment hook is in Xuanshi, and the rest is the stock. The double stock is on both sides. In addition to the merger, the shares can be merged. If the combination is removed, the shares can also be divided. Let the merger be multiplied by the hook and the truth. Add the difference to the merger and half of the shares. Its double is a vast combination. Let the Pythagorean see Those who multiply by themselves are the truth. The four truths are subtracted, the rest is opened, and the result is the difference. The difference is reduced by half, and the rest is the breadth. Reducing the breadth to the profound is what you want."

After Ye Chen finished speaking in one breath, the three scribes could only feel the ringing in their ears. Zhao Shuangxuan's diagram has long been recognized in the arithmetic circles, and it is an unsolvable diagram, unless it is calculated by heaven.But why this kid can figure it out, they are experts in arithmetic, although they are far from understanding what Ye Chen said, but they can also judge that what Ye Chen said is definitely not a random fabrication.

Cao Bin next to him witnessed this scene, his eyes sparkled, and he didn't know what was going on in his heart.But he didn't speak, and let the four continue.

Ye Chen saw the miraculous effect of being the first to win, so he didn't say any more. He raised his head at a 45-degree angle, looked at the tent, and put on a look of being too cold from a high place.

At this time, the old scribe had already rushed to the edge of the table in front of Cao Bin. Without further ado, he picked up the writing brush on it, tried to recall what Ye Chen said just now, and began to write seriously.It's just that he wrote more than 20 characters, but he couldn't remember anything.

"Do you two still remember how to explain the meaning of 'adding the difference between the real and the mysterious'?" The old scribe looked at the two middle-aged scribes and asked anxiously, frowning.

The two middle-aged scribes stood beside him and watched for a long time. If they still remembered that they had said it a long time ago, they could only shake their heads with a bitter face before he asked a question.

The old scribe glanced at Ye Chen, without any hesitation, quickly walked three steps in front of Ye Chen, bowed, and said, "Mister, please tell me about Zhao Shuangxuan's solution."

Hearing the voice, Ye Chen turned his head immediately, smiled reservedly, and said, "Mr., you are being polite. How dare you keep it private. Mister, just keep your notes." Pretending to be coercive should be done in moderation, otherwise it will be counterproductive. , it is better to be modest and prudent.

Hearing this, the old scribe couldn't help being ecstatic, bowed deeply to Ye Chen, turned around and walked to the table in three steps and two steps, and took the brush from the middle and upper scribe who had just picked up the pen, as if listening attentively.

Seeing this, Ye Chen changed Zhao Shuangxuan's graphic method, which would be solved by third-year junior high school students in the future, into the contemporary text style.Fortunately, he has always learned classical Chinese very well, otherwise he might not be able to speak clearly.

As soon as Ye Chen's voice fell, the three scribes looked solemn, surrounded the table as if no one else was there, muttered words, picked up a brush and another blank linen paper to write and draw, and it was clear that the three of them had already put Ye Chen and Cao Bin together. I forgot, and even forgot where I was.
