"It's not a secret, there are people from Kaifeng in Bianzhou, and their families have been making tea for generations. After Bianzhou became the land of gold, it made it difficult for us Han people to do business, and it can be said that we have been bullied over the years.

Seeing that the ancestral business was unsustainable, my father planned to leave Kaifeng and go to Jiangnan. Unfortunately, he encountered bandits on the way, and his belongings were robbed, and his parents died of illness on the way......"

Lu Fan recounted his past experiences, and when he talked about the excitement of love, it was difficult to hide his grief and indignation.

After listening to Lu Fan's story, Ye Yu understood the reason, and the heart was a place that couldn't be mixed up in the north.

Since it has been a generational tea making business, for Lu Fan, who has been cultivated in tea since he was a child, he is very familiar with a series of processes such as tea making and tea boiling.

However, this made Ye Yu suddenly think of someone, so he asked tentatively in a deep voice: "Since you are so intensive in the study of tea, I wonder if you have any research on the tea saint Lu Yu?" ”

"This book is written by the ancestors, and many people who make tea and understand tea have studied it, but there is no reason not to read it for their descendants!" Lu Fan responded very solemnly.

"What, you are really the descendant of the tea saint?" Ye Yu suddenly looked startled, and then asked.

Speaking of this, Lu Fan's waist seemed to be much straighter at the moment, and he said with a proud face: "I can't hide it, I am the twenty-first generation descendant!" ”

Ye Yu didn't expect that he would ask at random on a whim, but get this surprising answer. Xindao found a treasure today, so he said with a slightly excited expression: "I see, but Ye is disrespectful!" ”

"Don't dare! In the next five days, the grain of rice has not been eaten, if it is not for the grace of the father-in-law to give money, today is the next period of death! Please accept this worship for the reinvention of grace! ”

"Eh, don't be polite!" Ye Yu waved his hand, and then said, "I don't know what your plans are in the future?"

As soon as he asked about his future plans, Lu Fan's words suddenly became blocked, he sighed slightly after a moment, and laughed at himself: "What can you do in such a situation, you can only take care of food and clothing first!" ”

"Haven't you ever thought about going back to your old business? With your ability to make tea, wouldn't it be a pity if it was buried? ”

"My Lu family has been making tea for generations, how dare I forget it! In the future, whenever there is an opportunity, we will reopen the tea workshop and carry forward the Lu family's tea-making process! Lu Fan, who was still very lonely, really brightened his eyes when he talked about this matter, and said firmly with his fists clenched.

Ye Yu nodded, and said in his heart that there might really be a providence in this world, so he looked at Lu Fan and asked solemnly, "What if I give you this opportunity?" ”

"Engong, ...... you," Lu Fan asked in disbelief.

"But you have to promise me one thing!" Ye Yu did not answer Lu Fan's question directly, but directly threw out his own request.

"Eun Gong, please speak! If you are sent to the soup, you will not hesitate! ”

"If I open a tea shop, you will be the shopkeeper of this tea shop! That's my only condition, can you promise me? Ye Yu said this, looking at Lu Fan opposite with burning eyes.

"This ......"

Lu Fan was so stunned by this sudden surprise that he couldn't help himself.

The fluctuating mood looked at Ye Yu with incredible eyes. But when he looked at Ye Yu with a solemn face, he suddenly didn't know what to say.

With a pop, Lu Fan knelt heavily on the ground and solemnly bowed his hand to Ye Yu: "Engong is so trustworthy?" ”

"You don't want to leave outside the courtyard gate, in addition to telling me about these tea-making tea ceremonies, you also want to recommend yourself to make a job here with me, I don't know if what I said is right or not?"

Lu Fan, who was seen through by Ye Yu, was inevitably a little embarrassed on his face, and then said frankly: "I really have this intention below, I am not familiar with life in the land of Jiangnan, so I deliberately show my skills in front of Engong, in order to be a tea master in Engong's mansion......"

Ye Yu saw that Lu Fan was quite honest, so he smiled and said: "Isn't it useless for you to be a tea master with this ability, and you are just a powerful and rich servant in the end!" I, Ye Yu, don't suspect that I don't use people, so how can I make promises lightly? ”

"But if you are young and shallow, how can you ......"

Ye Yu waved his hand and interrupted Lu Fan's words: "If you have ambition, you are not old, and if you have no ambition, you will live a hundred years old!" Didn't I also create this family business in the year when I didn't reach the crown? ”

"Thank you for the grace of Engong's reconstruction!" Lu Fan said no longer hesitating, and 'bang bang bang' knocked his head on the stone slab three times.

Then Ye Yu instructed Uncle Sun to go down to settle Lu Fan, and when the courtyard returned to its former tranquility, a slight breeze swept through his cheeks, and Ye Yu showed an elusive smile in the direction of Lai'an Mansion.

……

At this time, in the Taishi Bureau of Lin'an Mansion, Yang Hui was reviewing one test paper after another.

Although there are not many answers, it is a big project for an old man who is nearly sixty years old. The triennial spring in the capital has just passed, and he, as a doctor of the Taishi Bureau, naturally participated in the review and grading.

The imperial examination in the Song Dynasty was divided into regular subjects, system departments and martial arts, which were roughly equivalent to modern unified recruitment, special recruitment, and military schools. There are several subjects in the regular course, among which the Jinshi department is the most popular in the world.

However, everyone in the world knows that the Jinshi in the imperial examination, but they don't know that at the same time, there are other subjects being examined, such as Yang Hui's Ming Arithmetic Subject.

Ming arithmetic, also known as arithmetic, belongs to the discipline of mathematics. Although this subject has been set in all dynasties, few people take the exam. Because for the literati who pursue fame and fortune, this is obviously not as good as the roots of the Jinshi Branch.

The so-called ten-year cold window no one asks, once it becomes famous and the world knows, it refers to the Jinshi list. As for this Ming arithmetic subject, which can be classified as a specialty in later generations, it will naturally not be recognized by the current literati.

No, Yang Hui, who was supposed to be in the Ministry of Rites and the main examiners, stayed in the Taishi Bureau to read the papers alone, which shows how far the scientific examination of the Ming Arithmetic Department has fallen.

Under the dim light, Yang Hui looked at the few answer sheets, put down the brush and lay on the chair, and couldn't help but sigh helplessly.

"Bullshit...... Bullshit! Yang Hui, who closed his eyes, couldn't help but let out such a sigh in his mouth.

Quietly in the room, there was only the cracking sound of the lamp, and Yang Hui, who had been quiet for a long time, looked at the answer sheet on the case with cloudy eyes, and couldn't help but smile bitterly: "Is this arithmetic really down to such a point?" ”

Everyone in the world is in pursuit of fame and fortune, and there are too few people who can calm down and do learning.

The academic nature of arithmetic is already very strong, even if the first in the imperial examination is only a professor in the Guozijian, and the best is only to study the astronomical calendar in the Taishi Bureau. With such a promising subject, who will be pure and hard-working?

Among the few candidates who apply for the Ming Arithmetic course every three years, most of them are candidates who have repeatedly failed the Jinshi course, or they are old and hopeless candidates who will take the Ming Arithmetic exam, in order to mix up the so-called fame.

He Yang Hui has been obsessed with arithmetic all his life, and he can be described as the Taishan Beidou of arithmetic in the Great Song Dynasty, but he should always need a disciple of inheritance when he is nearly sixty years old. But as soon as he thought of the students in the Guozi Prison, Yang Hui felt a wave of disappointment hit his body.

His cloudy eyes moved away from the answer sheet, and he picked up the teapot on the side to moisten his throat, but the entrance of the tea was a little cold. It seems that he only cared about reading the papers, and he forgot that the tea was cold.

I wanted to call the attendant to buy a pot of hot tea, but when I saw that it was getting late, I didn't summon the attendant, but got up with the teapot and walked out.

Crash!

Just as he got up and walked around the table, he accidentally dropped a book.

Yang Hui turned his head when he heard the sound, and bent down tremblingly to pick it up, but when his dry left hand was about to pick it up, he was attracted by two words in the book - mathematics!

This made Yang Hui unconsciously puzzled, wondering when he had this book on his desk?

Moreover, he had never heard the name of the book, but according to the name, it should be related to arithmetic. Thinking of this, Yang Hui picked up the book and put the teapot aside.

This suddenly reminded him of a book of arithmetic sent to him by his son Yang Zheng on Chinese New Year's Eve, because of the busy affairs of the Spring Expedition, he has not had the leisure time to read it, and now he thinks that it must be this one.

He Yang Hui is very knowledgeable about books such as arithmetic, but he has never heard of this book today, so he is curious about who wrote this book.

With this curiosity, he returned to his seat and slowly opened the book.

However, when he opened the first page of this math book, it was like a hammer hitting his heart.

As he read deeper, Yang Hui felt as if he had suddenly opened the door of his heart, making his cloudy eyes burst out with the brilliance of a young man.

As time passed, the attendant entered the room and added lamp oil twice, until the fifth watch of the rooster's crow, Yang Hui's eyes still did not leave this math.

When he saw the wonderful laws and formulas in the book, Yang Hui did not forget his feelings and excitedly performed the calculations on the paper. After repeating it many times, the table was already full of calculation papers.

This made the attendants on the side feel very stunned, how could he have ever seen Old Man Yang look like this. I secretly thought to myself, could it be that Old Man Yang was stunned by the madness of losing his heart?

When Yiqiē returned to calm, Yang Hui turned to the last page of the book, on which was the handwriting of his son Yang Zheng. After he carefully read Yang Zheng's account, Yang Hui's right hand holding the book couldn't help but tremble slightly.

At this moment, he was stunned and didn't know how to express his feelings at the moment, because this book was too important and shocking to him!

He didn't expect that the high-order square operation of the "Jia Xian Triangle" that he had painstakingly studied would be deduced by a doll less than twenty years old.

This derivation of the law of trigonometry is not only innovative and advanced, but also much more profound than his research!

Yang Zheng said very clearly in his detailed description that a young man named Ye Yu in Qingliu County had deduced the results of his life's pursuit two years ago.

This made Yang Hui unable to imagine how a sixteen-year-old boy could have calculated the law of trigonometry.

Just now, he calculated one by one according to the steps listed in the book, but it was exactly the same as the answer, which made Yang Hui suddenly feel that he was ten years older in an instant.

But after a long period of depression, it was replaced by more joy, because he was no longer bothered by the fact that there was no successor to the arithmetic......
