Wang Xin asked curiously: "If the Mohist family doesn't collect your salary and profits, will you still join the Mohist family?"
Xu Kai thought for a while and nodded.
"Why?"
"Sir, you said that Taoism is very likely to stand against me in the future. Before I become strong, I need a strong backer. Although Taoism has a stronger foundation than Mohism, its leaders are all Yasheng, so they must also It’s not much different. Moreover, the Mo family’s ideas and mine have some similarities.”
Mohism, along with "famous masters" and "numerologists", are among the hundreds of pre-Qin scholars who specialize in the study of "natural science". Although they also advocate the theory of ghosts and gods, they generally fall into the category of materialism. What's even more rare is that Mohism also has a strict definition of geometry. Its "Mo Jing" was written even earlier than "Elements of Geometry", but it did not establish an axiomatic method.
Wang Xin was silent for a while and asked, "Why don't you accept Zhang Sheng as your teacher?"
"Can you tell me directly?"
Wang Xin nodded: "Don't worry, I won't tell anyone."
"In mathematics, he is not as good as me."
It was said very directly, and to other people's ears, it was also an extremely arrogant statement. Who can compare to Zhang Cang, who is now a semi-saint, in the field of numerology?
But Wang Xin touched his chin and caught a word: "Mathematics? Not arithmetic?"
"Yes, I think arithmetic is not just a 'skill', but also a science, a science no less than any other."
"I admit your talent in this field, but how can you compare to Zhang Sheng, who has been studying the art of numerology for so long?"
Xu Kai said with a smile: "I asked Zhang Sheng a question. As expected, he shouldn't be able to solve it."
Wang Xin asked curiously: "Can you solve it?"
"I can't solve it either."
"...Then what's the use of saying this?"
"At least I know how to solve it. With all due respect, Zhang Sheng probably doesn't even know the essence of the problem." Xu Kai was very confident.
"Forget it, since you already have the measure, I won't say anything more." Wang Xin nodded and agreed with Xu Kai's statement, "Then which department do you plan to join?"
"Let's take a look first and then talk."
…
…
After seeing Mo Cen's bridge, Xu Kai began to wonder if the experimental props he had ordered would also explode with a bang.
Huang Tu found Xu Kai, and the two went to the cafeteria together.
"I'll be in the Confucian department in the morning and the Taoist department in the afternoon. I plan to go to the Legalist department tomorrow. How about you?"
Xu Kai was silent for a while and said, "I won't go to the Mo family anyway."
"Didn't you say last time that the Mo family is very suitable for you?"
"I suddenly felt like it wasn't for me again."
Huang Tu shook his head, obviously having a hard time understanding Xu Kai's erratic attitude.
"How about Confucianism?"
"Although I think the Confucian school is quite suitable for me, to be honest, their progress is too advanced. I am currently just preparing for the government examination, and I have never heard of many of the classics they talk about. Although the teacher speaks well Very good, I can understand the meaning without reading those classics, but those students answered fluently, which shocked me a little."
"Is such that."
Huang Tu suddenly asked: "Why did you refuse Lord Zhang Sheng's offer to be a disciple?"
Xu Kai didn't have so many scruples in front of Huang Tu: "I don't think he can teach me."
Huang Tu looked at Xu Kai a few more times and asked, "Have you relapsed?"
"I've said it many times, can't you just wait for me?"
"Then tell me your reasons! If the Half-Saint wants to accept me as his disciple, I will lick his shoes even if he wants me to."
Xu Kai glanced at Huang Tu with contempt: "If you really lick it, maybe the Half-Saint will not accept you as his disciple even if he originally planned to do so."
"That's right. Those half-saints hate those people who are just like dogs and cats." Huang Tu nodded and continued to eat.
"Since you are also going to the Legal Family Department, then I will go and have a look too."
The Legalist family is based on the rule of law, and the rules are probably stricter than those of the Mohist family, but it doesn't matter if you just go and have a look.
Huang Tu wanted to sit in the first row, but Xu Kai forced him to sit in the last row.
Then he was accurately called by the teacher.
"The student in the last row, I heard that you just entered Tianxiang. The fact that you came to take classes in our Legalism Department means that you should also be interested in Legalism. So how much do you know about Legalism?"
Xu Kai scratched his head and said with some uncertainty: "Everything has potential...?"
Huang Tu quickly pulled Xu Kai and whispered: "Are you stupid? That's from the Buddhist family!"
Sure enough, the atmosphere in the classroom became weird. If the law on illegal genealogy was strict, the whole crowd would probably burst into laughter.
The teacher also had a livid face and said slowly: "Classmate Xu Kai is really knowledgeable. He even knows the contents of Buddhist classics that have been passed down for tens of thousands of years. However, although I cannot interfere with your decision, I still suggest that you Don’t come to the Legal Family Department.”
If Xu Kai hadn't been considered a student of the Legal Department, he would have kicked him out long ago.
After class, Xu Kai asked curiously: "There are temples in Tianyan Continent, but why is it said that the Buddhist tradition has been cut off for tens of thousands of years?"
He has seen Buddhist temples in Shangyang County. When they left Shangyang County, Huang Tu gave him an example of the relationship between a monk and a Taoist priest.
Huang Yu looked at Xu Kai as if he were a fool: "You will know this kind of thing if you go to the bookstore more often. This is extremely basic knowledge."
Xu Kai only understood some basic customs and customs, but didn't really know much about the specific history of Tianyan Continent, so he asked, "Then can you explain it in detail?"
"In fact, there was Buddhism before. It is said that Buddhism appeared earlier than the way of literature and energy. Buddhism existed when human beings were still practicing the method of introducing qi into the body. After the establishment of the way of literature and energy, Buddhism also entered the world. Xiang is its own lineage. But later, for unknown reasons, Buddhism began to decline. Until now, there are only some mortal temples, and there are no longer people who can use Buddhist classics to complete the cultivation of literary spirit."
"Could it be that he failed to adapt to the change from the method of introducing Qi into the body to the way of human civilization?"
Huang Tu shook his head: "If we can't adapt, how can Tianxiang let the Buddhist family enter Tianxiang to establish a line? As of now, it is impossible to know when the Buddhist family began to decline."
"Ah, I know something about this."
This voice was very familiar to Xu Kai, and Huang Tu was also very familiar.
"Yun Qingshan?! Why did you come to Tianxiang?" Xu Kai was very surprised.
Yun Qingshan smiled kindly and said: "Thanks to Xu Kai for knocking over my desk and messing up my test papers. Otherwise, how could I have exploded and become a full-A candidate and qualified to enter Tianxiang? ?”
Xu Kai looked at her kind smile, but he clearly felt a biting chill.
"It's not my fault! The yellow picture was also smashed down at that time, why don't you blame him!"
"Hey, that's how you sold me, right?" Huang Tu was grabbed by Xu Kai just as he was about to run away, and he scolded Xu Kai angrily. He wanted to escape from the scene, but couldn't escape Xu Kai's clutches.
"Okay, okay, I don't want to blame you." Yun Qingshan waved his hand, "You just said you wanted to know the reason for the decline of Buddhism, right?"
Xu Kai nodded: "I am indeed a little curious."
The three schools of Confucianism, Buddhism and Taoism, Confucianism and Taoism, are all flourishing in Tianyan Continent. Why has Buddhism declined? According to Huang Tu's description, when Tianxiang was still at Qufu Academy, Buddhists were invited to give lectures. Although Buddhism is a religious belief, some of its principles still have merit.
"I don't know the specific reason, but I have read a record in a classic. It seems that a treasure inherited by the Buddhist family broke apart in an accident. As a result, the Buddhist family was unable to pass on the inheritance and gradually declined."
"Inherited treasure?" Xu Kai asked doubtfully, "Buddhist inheritance is so fragile that it cannot be passed down if a treasure is lost? And for the way of literature and spirit, classics are more important than treasures, right?"
"So I don't know the specific reason." Yun Qingshan said with a smile, "It is said that the saints are also exploring this issue, and I just accidentally saw this record."
Xu Kai thought that given the other party's mysterious background, the book's statement might actually be credible.
"And with the decline of Buddhism, almost all Buddhist classics have been lost. Only some extremely rare classics exist in the world. You actually know a Buddhist mantra. It seems that you are really well-read."
However, Xu Kai suddenly thought that since the Buddhist scriptures in Tianyan Continent were lost, could he reproduce some Buddhist scriptures to assist his practice?
Thinking of this, he suddenly shook his head. His understanding of Buddhist knowledge is limited to "Guo Zi talks about the Tathagata." Does he have to go on stage to talk about "Tathagata, has he come? Is he the Tathagata?"
forget it.
"What are you shaking your head for?" Yun Qingshan asked curiously.
"Nothing. Why are you in the Legal family? Have you already decided?"
"I'm about the same as you, I'm still studying. But what are your plans?"
Huang Tu said: "I should go to the Confucian school, but I am a little interested in the famous scholar's 'White Horse is Not a Horse'. Let's go and have a look tomorrow."
Xu Kai thought about it. At present, he didn't think that any of the hundreds of schools of thought in Tianxiang was suitable for him. If I had to say it, I might be about to establish a new line of numerologists, but I had just rejected Zhang Sheng's offer to be a disciple, and then turned around and wanted to become a disciple of someone else's numerologists. I'm afraid it would be a bit embarrassing.
"I wonder how Zhang Cang's Goldbach's conjecture has been proven?"
…
…
In Zhang Cang's other courtyard, the calculation manuscripts overflowed outside the other courtyard, leaving the four authors of "Song and Yuan Arithmetic" who came to visit not knowing what to do.
With the writing speed of a semi-sage and the fact that he already understood the axiomatic method, he spent a day rewriting "Nine Chapters of Arithmetic", which solidified the foundation for his sainthood.
So he sent a message to the four people, inviting them to come over the next day to talk, and then began to devote themselves to the great project of proving Goldbach's conjecture.
"Lord Zhang Sheng, what's going on?" Qin Jiushao asked doubtfully.
"Song and Yuan Arithmetic Books" does not refer to one book, but to the arithmetic books of the four authors with the highest achievements in numerology. Because it is difficult to distinguish between them, they are often referred to together, and the relationship between the four people is therefore not bad.
However, since Zhang Cang became a saint, they are no longer the highest achievers of the numerology discipline.
"I don't know, there are so many manuscript papers, what are the calculations? Why can't I understand something?" Zhu Shijie picked up a piece of manuscript paper and looked at it over and over again, but he didn't understand what the calculations were about.
As if hearing sounds outside the room, a sigh came from inside the room, and then the owner of the room said: "Everyone, please come in first."
The four people entered and carefully pushed aside the manuscript paper blocking the way, but heard the person inside say: "Don't worry, it's just useless paper."
"Master Zhang Sheng is joking. This is all written by the semi-sage. How can it be called waste paper?"
"If it were a Half-Saint from other families, there would be some truth in saying this. But to me, a numerologist, the wrong calculation paper is worthless, not even worth the weeds on the roadside."
The four of them looked at each other and felt that this was quite reasonable. They thought that this might be Lord Zhang Sheng giving them guidance.
The four of them bowed together and said, "Thank you Zhang Sheng for your teaching."
"Don't talk about the extra stuff, just come in first."
With Zhang Sheng's permission, the four of them had no scruples and swept aside the manuscript papers.
Finally seeing Zhang Sheng's true appearance, the four of them were shocked: "Master Zhang Sheng, how could you do this!"
However, Zhang Cang's rosy face, which was originally rosy due to his breakthrough to semi-saint, shriveled up again, his eyes were bloodshot, and the hand holding the pen was a little shaky.
Zhang Cang coughed a few times and said, "You should also know that I discovered a good seedling a while ago and want to take him under my wing and teach him personally."
"With Master Zhang Sheng's appreciation, that boy is truly a lucky man."
"But he rejected me and gave me a question, saying that if I could solve the question, he would sincerely accept me as his teacher." Zhang Cang put down his brush and sighed, "I calculated It’s been a day, but I still don’t have a clue.”
"What problem can be difficult for Mr. Zhang Sheng?" the four people asked in confusion.
The power of the Semi-Saint reaches the sky and the earth. He has insight into the world and can make deductions and predict future events. Not to mention the numerologists who specialize in this. But what was so difficult for Zhang Cang was actually just an arithmetic problem?
Zhang Cang told the four people the questions Xu Kai asked him.
After listening to this, the four people all frowned, and Qin Jiushao said displeasedly: "The art of numerology is meant to solve worldly problems, such as fields, accounts, etc. This question does not involve anything in the world, it is so illusory. , even if it is solved, what good will it do to the people, the country, and our race?"
Zhang Cang said quietly: "Do you know where the opportunity for me to become a saint comes from?"
The four of them were extremely excited when they heard this. They had been stuck here for a long time and could not find the opportunity to become a saint. If Zhang Cang's breakthrough to Half-Saint had not brought them great confidence, they might have started to I have plans to switch to another department.
Zhang Cang took out a book and said quietly: "This is my opportunity to become a saint."
The four of them stepped forward to take a look and saw four large, crooked characters written on the cover.
--Euclid.
"This book was written by the student who asked me that question."
