Cross Country Little Master

When Eunuch Cao made a point in Liujia Village, Fang Ruixuan guessed that the emperor might have summoned Shen Huiming because of the modern mathematics he taught to Shen Huiming.

He brought the textbooks he had compiled for the three apprentices into the capital, and even took time to transcribe them on the way.

At this time, it happened to present the transcribed copy to the emperor face to face.

"Fang Juren came prepared." The emperor signaled Eunuch Li to present the book presented by Fang Ruixuan.

Fang Ruixuan was frightened by the emperor's short words. The emperor would not think that he was guessing. People in power are very jealous of these things. Cao Cao killed Yang Xiu because of this. He didn't want to die young .So Fang Ruixuan quickly explained, "Yesterday, I met with the young disciple and learned that the emperor is interested in these things, so I brought them into the palace. I also ask the emperor not to blame the grassroots for trying to figure out the emperor's heart."

The emperor didn't say anything, and started flipping through the book Fang Ruixuan brought, part of which Shen Huiming had told him was easier to understand, so he flipped through it casually.When the emperor saw a chapter called coding, he took a breath.

"Fang Juren's chapter on codes is very interesting." The emperor said inexplicably.

"Back to the emperor, this is a game I played with my disciples when Caomin was teaching." Fang Ruixuan answered bravely. Shen Huiming revealed a lot of old things to the emperor, and he dared not tear up these chapters rashly.

At the beginning, in order to open up several ways of thinking for the apprentices, I taught a lot of advanced things.

"This game is very interesting, and there are many uses for benefiting the country and the people. Fang Juren said, right?"

"Yes, your majesty knows the pearl with his eyes. This is just a game in the eyes of the grassroots. You can see it and it will have a great effect. The grassroots admire it very much." Fang Ruixuan said in an extremely doggy manner.

But this flattery seemed to hit the horse's leg, "Fang Juren is too modest. Fang Juren can teach a student like Tan Hualang, so how can he not know the usefulness of this game." The emperor specifically emphasized the word game.

Fang Ruixuan couldn't tell the joy or anger from the emperor's voice, and it really was like accompanying a king like a tiger.

He quickly knelt down and pleaded guilty, "The grass people are guilty, but the grass people did think of it as a game at the beginning." Fang Ruixuan bit to death that it was a game, and then said, "The grass people are among the people and have no official position. Since he has no way to dedicate this thing to the emperor, he just wants to wait for his disciples or descendants of the Fang family to pass the imperial examination in the future, and then present it to the emperor in the court, which is considered a credit."

Thinking back to the second uncle in the original body, he also had this idea and had that thing.Fang Ruixuan now feels that the thing is so hot that he dare not hand it over.

"Fang Juren also tried his best to plan for his descendants. It's just that Fang Juren is so talented, why didn't he become an official in the court and solve my problems for me." Knowing that the youngest son of the Tang family was teaching at the Fang Family Academy, the emperor didn't believe it all. Fang Ruixuan's rhetoric.He just wants to make benefits for future generations. He can still accept such selfishness.

I don't want to die too fast.Fang Ruixuan wailed in his heart, but said another way.

"My Majesty, when the people were in turmoil a few years ago, the grass people's family suffered great changes. The wives and children of the clan died at the hands of the refugees. The grass people were discouraged and lost the will to survive. Fortunately, I met my husband. There are still many people who are suffering, how can the grassroots say death so easily."

"Caomin married Fulang, and he and Fulang supported each other, and then they slowly cheered up. It's just that they have been abandoned for a long time, and they have long lost the enthusiasm to serve the court. They just want to live together in the mountains and fields with Fulang for the rest of their lives."

"It's common for men to have three wives and four concubines. You treat your husband so well, you are not afraid that he will ride on your head." The emperor was in a very good mood when he heard Fang Ruixuan's words, and joked.

"Back to the emperor, Caomin's husband is the most responsible. Even if Caomin let him ride on my head, he would not give up. We also have a pair of lovely children under our knees. Even for the children, Caomin is also reluctant to give up. Use other female brothers to make Fu Lang sad." Fang Ruixuan brazenly praised Liu Sheng and boasted to himself.

"Fang Juren is a rare person with the most affectionate nature." The emperor praised him.

"Don't dare. If the emperor is interested in this code, there are several other methods here, which are not written in this book."

"Oh, let's hear it." The emperor also became interested. This thing is very useful in the secret affairs of the army and the court.

Fang Ruixuan seriously told the emperor several commonly used passwords, as well as the binary writing method of numbers, which made the emperor very happy.

"This so-called binary number is in line with the Taoist theory that one life is two, two is three, and three is all things." The emperor nodded.

"What you said is that the knowledge of Taoism is extensive and profound."

The emperor summoned and talked with Fang Ruixuan for more than three hours this time, which surprised some people who were concerned about this matter, and they all asked around, what did the emperor say to Tan Hualang's mentor.

I thought I was just a young man who could teach, but I didn't expect to get the emperor's favor so soon.

Should it be said that he is Tanhualang's teacher?

Tanhualang was reused by the emperor just because of his birth, so what did Tanhualang's teacher rely on.

The emperor and Fang Ruixuan talked very happily, until the time when the palace gate was locked and it was time for Fang Ruixuan to leave the palace, there was still something to be desired.

"Fang Juren, you said that the method of numbers came from overseas?"

"Go back to the emperor, yes."

"I named it Fang's counting method, Fang Juren can understand what I mean."

"Yes, Cao Min understands, Cao Min thanked the emperor for his kindness." Fang Ruixuan knelt down and thanked the emperor.

What does the emperor mean? He just feels that such a great invention is a little unhappy under the name of an imported product.They are rich in land, resources, and talents, how could they not have talented people in this area.

Didn't Fang Juren invent the method of representing numbers with symbols?

Although such a bandit logic is very cool, it seems that the emperor's calculations have come to nothing.

Historians of later generations, after serious textual research, drew the following conclusions from the clues obtained from the notes of Fang Juren and his husband Lang Liusheng. Fang Juren was the first to introduce Arabic numerals in Chinese history and spread them widely. Fang's counting method is a Chinese name given by the then emperor Wende to facilitate the spread of Arabic numerals in Dayan.

Fang Juren and the predecessor who created numbers in ancient India did not complete the creation of calculus like Newton and Leibniz, but invented the symbolic method of numbers.Numbers were invented by Indians, and Fang Juren is just a communicator.

Although Emperor Wende did not do anything to promote the dissemination of numbers during his lifetime, he hid this method and used it in the army to encrypt intelligence and encode confidential events.Historians still arbitrarily believe that Emperor Wende made a great contribution to the spread of Arabic numerals in China.

Let future generations talk about the things of later generations.Now Fang Ruixuan is on the way out of the palace, feeling a little restless.

Was he plagiarized?But it is still aboveboard, and the plagiarism is ordered, and the name of a plagiarist must be blatantly passed on to the world.

In this way, he has indeed left his name in history, and he will still be famous for a long time.Just waiting for those people who love to research and discover this, will they give him such an evaluation as a thief who deceived all future generations.

Anyway, it is impossible for a thief like him to compete with the Lord.After all, Arabic numerals were invented in the third century A.D., and it is probably in the eleventh century A.D. now.

Fang Ruixuan was a programmer in his previous life, and had a strong sense of patents, so he has never been able to do things like other time travelers who impersonate others and occupy the fruits of other people's mental labor.

Now, in front of the imperial power, he had to do it.

During the day, Fang Ruixuan returned to Shen Huiming's mansion exhausted from dealing with the person on the dragon chair, tidied up and had dinner, then fell asleep with his wife in his arms.

Shen Huiming wisely didn't bother Fang Ruixuan, he and the Yao family took the route of pure ministers, and it didn't matter whether he knew what the emperor had talked about with Fang Ruixuan.

Moreover, he just left the teacher and caused such a big trouble for the master, it is lucky that the master does not blame him.
