"You have to trust me in this case."
Tianxiang Bookstore, which was still whispering, fell into an eerie silence.
Huang Tu said earnestly: "It's not that I don't believe you. Do you know what it means to face the God's Will List directly?"
"Don't worry, wait until I finish writing this poem."
"Recalling Qin'e·Loushanguan"
The west wind is strong, and the wild geese in the sky are calling Shuang Chenyue.
In the frosty morning and the moon, the sound of horse hooves breaks and the trumpets sound.
The long road through Xiongguan is really like iron, but now we are crossing it from the beginning.
From the beginning, the mountains are like the sea, and the setting sun is like blood.
Huang Tu stared blankly at the poem, blankly looked at the exclamations and appreciations around him, blankly watched the golden light coming from the sky, and then blankly looked at Xu Kai.
Xu Kai picked up this poem with satisfaction. It was worthy of being written by a great man. This poem made his literary style grow even more.
But there is still the same problem, the conversion rate is too low. It is good to occasionally write something to show your holiness in front of others, but you cannot make it your own path.
My own path lies in modern science.
But Huang Tu couldn't help it anymore and asked directly: "Has your kid been kidnapped?"
Xu Kai was furious: "Are you a shameless kid? If I write a good poem, you think I've been robbed of my life?"
Huang Tu looked at Xu Kai carefully and suddenly asked: "Who are you?"
"I'm Dad."
Huang Tu nodded: "It seems not."
"Is this how your kid identifies?"
Ignoring the compliments around him, Huang Tu asked directly: "Are you serious about taking part in the imperial examination in the form of facing the God's Will List?"
"You know, I'm not joking about this."
Huang Tu said seriously: "Do you know the consequences of failure?"
"First, the literary energy will be destroyed, and even worse, the meridians will be destroyed, and even worse, the body will die." Xu Kai shrugged, "Besides, I don't think I will fail."
Huang Tu was silent for a while and said, "I think you have become more confident than before."
Xu Kai patted Huang Tu's shoulder again: "If you could become a scholar of the Holy Path, you would be as confident as me."
…
…
Xu Kai went straight to the third floor. As expected, he didn't hear the sound from downstairs while going upstairs, and he didn't know how he had delivered the message to the people on the second floor.
Generally speaking, the higher the floor, the more valuable the books. But there is something special about numerologists. Although there was no semi-sage before Zhang Cang, because numerology is widely used in all aspects of life, such as measuring acres, accounting, building calculations, etc., numerologists also have a high status. A certain generation of emperors even included numerology as a required subject in the Imperial College.
Xu Kai found "Nine Chapters of Arithmetic", which was a version that Zhang Cang had not yet rewritten, but Xu Kai wanted to take a look at this version.
Ancient mathematics is not without its merits. For example, the Dayan Unification Technique proposed by Qin Jiushao, also known as the Chinese Remainder Theorem, has shone brightly in later generations of computer science and cryptography, and has a high status.
Suddenly someone came to Xu Kai and asked, "Are you Xu Kai?"
Xu Kai turned back to look at the man. He was eight feet tall and had dark skin. It would be unsurprising to say that he was middle-aged in his forties. Xu Kai felt that this person looked familiar, so he agreed: "That's right. What do you do for me?"
"I heard that you rejected Lord Zhang Sheng's offer to be a disciple."
Has this matter spread? Xu Kaixin thought there was something wrong with this.
"I, Zhao Chang, are from the same lineage of numerologists as you."
Xu Kai was even more puzzled: "Since you can't bear to see me rejecting Zhang Sheng's apprenticeship and coming from the same family as me, why do you want to trouble me today? Why don't you come earlier?"
Zhao Chang was stunned: "Who said I was here to cause trouble?"
Xu Kai was stunned: "Then what are you here for?"
Zhao Chang sat opposite Xu Kai and said: "I heard that you plan to face the Heavenly Will List. If you can be accepted by Lord Zhang Sheng as a disciple, you must be extremely talented. Although our numerologist has many great sages, now we have Zhang Sheng. You are in charge, but the decline in the past is hard to hide, and you have not found any geniuses in these years. To a certain extent, you can be said to be the most talented person in our math department at present."
"Thanks for the compliment."
"But you shouldn't go to face the God's Will Ranking." Zhao Chang's eyes were sharp and his expression was serious. "Although you are a scholar of the Holy Path, it is not unprecedented for you to participate in the Face to God's Will Ranking. As far as I know, there have been four Scholars of the Holy Path participated in the list of facing the will of God, but only one person passed."
"Classmate Zhao, don't you believe that I am one of the quarter?" Xu Kai said with a smile.
"We can't bet." Zhao Chang raised his voice, causing some people nearby to look over. Seeing this, Zhao Chang lowered his voice and said: "Xu Kai, you have a peerless talent, there is no need to rush for a while. The benefits gained from facing the God's Will List are undoubtedly huge and unimaginable, but that is something we can talk about after we succeed. Let's count the numbers The artist has been weak for a long time and cannot afford to lose a genius like you."
Xu Kai understood. If what he said was true, he was really a good senior who cared about the mathematics department. The birth of a genius can save a declining faction, and for the current numerologist, he is that important genius.
What was even more difficult for Zhao Chang to understand was that even if he failed to pass the government examination, he could still take the Half-Saint as his teacher, and there would be no need to worry about being dropped out of school by Tianxiang. In this case, why should we be so radical and take the road of facing the list of God's will?
"Senior brother, don't worry, I'll figure it out myself."
Zhao Chang's voice was a little anxious: "Xu Kai, do you know the difficulty of your choice? Especially the questions from my lineage of mathematicians are more complicated than those from other departments! You..."
Xu Kai interrupted him: "I wonder what senior brother's state is now?"
Zhao Chang took a deep breath and said: "I have now passed the Jinshi examination. After I am promoted to Qingyun, I will return to Daxia and join the officialdom."
Those who choose to become an official after becoming a Jinshi are called Qingyun Realm, which means straight up to the top, and are on par with the Holy Dao Realm. It's just that the methods of the two have different emphasis.
Xu Kai nodded: "How about you and I have a battle on the subject of mathematicians? If senior brother loses to me, stop trying to persuade me, and help me stop other people who have the same purpose as you. people."
"Okay." Zhao Chang stood up, "Since I passed the Jinshi examination, I have had a lot of time to study numerology, and I did not neglect the study of numerology before. My level of spirituality in numerology is not You can imagine.”
He came to the door of the book pavilion, turned to Xu Kai and said: "If you lose, don't face the God's Will List again."
Xu Kai smiled and said: "Senior brother, don't forget what you said."
…
…
If both parties in the literary fight are at least Juren, then the scene of the literary fight is actually not much different from the scenes in the novels that Xu Kai imagined. It is nothing more than using poetry to attack and defend, and using literary spirit to use various secret techniques to fight.
And Xu Kai is just a scholar of the holy way, so the fight between the two of them is really not much different from that of a literary society.
On Tianxiang Literary Battle Stage, a teacher from the Department of Mathematics stood on the stage, looking at the two people who proposed the literary battle. And there were countless people watching in the audience.
"Did you hear that the scholar of the holy way refused Lord Zhang Sheng's offer to be a disciple..."
"What? Could it be that he already has a teacher, so he refused to accept Master Zhang Sheng as his disciple?"
"I don't know. It is said that there is no such thing. No one knows why he refused...and what's even more outrageous is that he also proposed to face the God's Will List!"
"What?! Isn't this a bit arrogant? It's just that he refused Master Zhang Sheng's offer to be a disciple, but he actually dares to face the Heavenly Will List?!"
"This classmate has been in Tianxiang for less than a month, but he has caused so many waves. It's really interesting..."
Xu Kai, who had taken the Raw Blood Bone Grass and the Heavenly Blood Beads, could clearly hear the whispers in the audience, and felt that he seemed to have underestimated the status of the list of facing God's will in everyone's hearts. Historically, no more than ten people have passed the imperial examination in this way, which is even less than the number of people who have passed the imperial examination. Although the benefits are extremely rich, compared to the huge risks, people who choose this method are almost extinct now.
The teacher on the stage has already begun to read out the rules: "Since this is a literary battle of our numeracy family, and both sides have made demands, then this time it is not comparable to the classics of all saints, nor to lyrics and lyrics, but only to my numeracy master." The question of pulse. Both sides take turns to ask each other a question until someone cannot answer it. The person who cannot answer the question will lose. But if the person who asked the question cannot answer the question he asked, the person who asked the question will lose. Do you understand? "
Seeing the two of them nodding, the teacher clasped his hands together and announced: "In that case, the literary fight begins."
"Junior brother, please go ahead." Zhao Chang extended his hand to signal, showing off his senior brother style.
"No, no, no, senior brother should invite me first." Xu Kai shook his head and rejected the other party's proposal.
It would be too disrespectful for the other party to end this with the first question.
After all, the other party at least has good intentions.
Zhao Changchang saw that the other party insisted on this, so he said: "Since junior brother insists on this, then I will make a fool of myself. I just hope that junior brother will not be defeated at the first question. If this is the case, then it is a good thing for me to dissuade junior brother from facing the God's Will List directly. ."
After that, he read out his topic: "I heard that you are very weak in the classics of all saints. You have not even read Master Zhang Sheng's "Nine Chapters of Arithmetic". In this case, I will give you a lesson from "Nine Chapters of Arithmetic". Question: There are pheasants and rabbits in the same cage. There are thirty-five heads on top and ninety-four legs on the bottom. What are the pheasants and rabbits?"
After saying that, he looked straight at Xu Kai, his expression seemed to say that if you don't know this question, then why are you going to face the God's Will List?
Xu Kaixin wondered if the other party was looking down on him too much, so he said directly: "There are twenty-three pheasants, and there are twelve rabbits."
"method?"
"Suppose the number of pheasants is A and the number of rabbits is B. According to the question, we can know that A and B add up to thirty-five, and A's product of two plus B's product of four is ninety-four. The solution can be used to get the number of pheasants and rabbits. "
Since Zhang Cang has not promoted simplified numbers and English letters yet, Xu Kai still uses Chinese characters.
After hearing this, Zhao Chang was stunned. Even the teacher glanced at Xu Kai with surprise in his eyes. As for the students in the audience, they also started whispering.
"I have read some arithmetic books, but I have never seen the method proposed by Xu Kai..."
"The ideas are clear and unique. This method does have some merits."
"Maybe Xu Kai can really win?"
"Don't think so much. As far as I know, Zhao Chang may have been immersed in numerology for a longer period of time than Xu Kai. How can he compare to Xu Kai, who has just entered Tianxiang?"
"Hey, I really hope that Xu Kai can win. It's been too long since I've seen anyone who participated in the list of facing God's will..."
Zhao Chang came back to his senses and nodded: "Xu Kai is worthy of being proposed by Master Zhang Sheng to accept a disciple. This method is indeed excellent, so please also propose a question."
"Today there is a rich businessman who hires a worker. He gives the worker twelve taels of silver and a piece of clothing. The worker is about to leave in the seventh month, and the rich businessman gives him five taels of silver and a piece of clothing. How much is this clothing worth?"
After saying that, Xu Kai took a sip of water. It was too difficult for him to describe mathematical problems in classical Chinese, so he came up with this after thinking about it for a long time.
Hearing this question, Zhao Chang fell silent obviously. He took out a pen and paper, frowned and thought for a while before giving the answer: "Four taels and two-fifths two-quarters."
That is 4.8 taels.
"How to ask for it?"
"If he earns a normal income, he can get seven taels of silver and seven-twelfths of a piece of clothing for this job, but his final income is five taels of silver and one piece of clothing. Subtracting the two can give him five-twelfths of the price of a piece of clothing. It’s two taels, and then we can get the price of the clothes.”
Xu Kai applauded and smiled: "Senior brother's method is somewhat similar to my method of solving the problem of chickens and rabbits in the same cage."
"I was inspired by your algorithm to solve this problem, otherwise I might have spent more time." Zhao Chang said calmly, "But my next problem won't be that simple."
"Brother, feel free to come."
The two asked each other questions, and Xu Kai could often answer Zhao Chang's questions quickly, but Zhao Chang often had to think hard and meditate, with a lot of cold sweat on his forehead, before he finally answered.
No matter how strange these questions are, they are still within the category of elementary mathematics, and there are no Mathematical Olympiad questions in this world that mainly test mathematical thinking. For Xu Kai, these questions are really not difficult.
In the fifth round, Xu Kai thought that he could no longer waste time like this, and he had given Zhao Chang enough face, so he threw out his prepared trump card: "There are two people playing pot throwing now. The probability of A making the throw is 5 Three out of three, the probability that B will make a successful throw is 1/2. Let’s ask the probability that after ten throws, B will make more successful throws than A.”
Xu Kai has completely abandoned classical Chinese and directly described in vernacular.
When he heard this question, Zhao Chang froze, frowned, and looked at Xu Kai. After receiving a positive answer, his expression became darker and darker. He clenched his pen, sweating more than before.
Xu Kai directly attacked the weaknesses of ancient mathematics. Although China's mathematical level has been much more advanced than that of the West for more than a thousand years, there is no problem about probability theory. Although the term probability exists, it has not been studied in depth in mathematics. Because this aspect is generally believed to be related to things like the Book of Changes and divination, numerologists have not studied it.
The situation in Tianyan Continent is very similar in this regard.
After thinking hard, Zhao Chang finally put the pen down and said: "I don't know how. If you can do it, junior brother, I am willing to admit defeat."
Xu Kai confidently wrote down some probability laws related to this question and proved them. This took Xu Kai about a quarter of an hour. He then solved the problem on the basis of these laws.
Zhao Chang stared blankly at the manuscript paper in Xu Kai's hand.
Xu Kai smiled and said: "Senior brother, you lose."
…
…
The next day, Xu Kai woke up early in the morning and was just about to wash up when he heard someone knocking on the door.
"Who's coming again?" Xu Kai frowned.
Yesterday, he defeated Zhao Chang in a literary battle and received a gasp of air, but he seemed to see some people leaving with gloomy expressions.
Could it be that someone really is here to cause trouble this time?
Xu Kai went to open the door, and it was Mo Cen who was outside the door.
"I worked overtime to make everything you asked for."
Xu Kai was very surprised and said: "Didn't you say it would take a month? I didn't ask you to rush the work and I won't pay you more."
"I won't ask for more wages from you. It's time to pay the balance."
Xu Kai nodded and took out the token Wang Xin gave him. This token had the effect of a bank card. Mo Cen also took out a similar token. When the two touched each other, the balance was paid. That’s it.
Since the thing Xu Kai wanted was larger, the two went to the Mo family to get the props customized by Xu Kai.
"Why did you suddenly speed up and complete what I wanted?" Xu Kai asked on the way.
"I heard that you are going to face the God's Will List. I'm afraid that if you die there and no one will pay me the balance, I'll finish the things first." Mo Cen said sincerely.
