It was the second day that Ren Baqian saw Qinglian.
In fact, Ren Baqian knew that this team passed through Pingcheng thirteen days ago, and he only found out that Qing Lian was in the team last night.
Ren Baqian saw a slim woman waiting in front of the school early the next morning.
The previously arranged time to summon Qing Lian was this afternoon, but seeing her at this time, Ren Baqian knew in his heart that he was here to get acquainted first. After all, he was also his student, so Ren Baqian let him in without saying anything.
The two of them sat down, and Ren Baqian looked at his heartbreak. After more than a year in the rebel army, he hadn't changed much, his skin hadn't turned dark, and his person hadn't changed in determination.
"Prefect! I'm here to return the books!"
Qinglian has a wider forehead and a bit bigger mouth, but these are not flaws on her face, and she smiles very beautifully. The most important thing is that she has a student-like temperament, which is rare in this world.
Ren Baqian brought over several books, three of which were on mathematics and two on probability.
One of them also covered calculus.
For this world, it is quite advanced knowledge.
Well, it can be regarded as quite complicated knowledge on Earth, and I don’t know how many people want to die.
Anyway, Ren Baqian knew that if he wanted to pass by himself, it was no less difficult than defeating the Empress.
"Understood?" Ren Baqian had a kind smile on his face, full of malice in his heart, letting you natives from other worlds also experience the power of "calculus".
Originally, I thought about locking my group of students in the classroom for a few years and let them face this calculus and pluck their hair, but I didn't expect someone to see it in advance.
"I understand most of them, but there is still one thing I don't quite understand. I am going to ask the governor for advice! Regarding the fixed point theorem, there is always something I don't want to understand..."
Qing Lian took out a wooden board and carved numbers on it with a hairpin as she spoke:
"It is here that, if F is a continuous mapping from the sphere to itself, there must be a point c such that F(c)=c or -c. That is, F either has a fixed point, or has a point mapped to it Antidiametric point…”
The smile on Ren Baqian's face suddenly froze.
The horrible memory dominated by calculus resurfaced in my heart again, bursts of toothache, and the urge to pull my hair down...
Oh, and now there is no hair.
"Stop!" Ren Baqian hurriedly stopped him, with a strange expression on his face, "You came back to test me today, right?"
"How can it be? I'm also a student of the governor. I'm here today to ask for advice. Regarding this question, I don't think anyone in this world can answer me except the governor!" Qinglian said, blinking her eyes.
Think about the reason why Ren Baqian rejected him at this time, the real probability of the reason Ren Baqian said is 30%, the probability of not being able to answer is 50%, and the other probability is 20%...
In other words, Ren Baqian had a 50% chance of being able to answer his own question.
And the probability that I will meet other people who can answer this question within three years is one in a million, in ten years or so the probability is one in ten thousand, and in twenty years, the probability is one percent.
This probability increases with time, that is to say, there is a high probability that I will meet someone who can answer my questions after twenty years... It's been too long...
Still have to rely on Prince Zhao.
Ren Baqian felt goosebumps all over his body inexplicably, and he suddenly felt that Qing Lian's calm and peaceful expression... was probably a devil, right
Ren Baqian will never touch calculus again!
But at this time, he couldn't give up.
"The students you know are about to graduate in two months. After graduation, some of them will continue to learn more advanced knowledge. If you can give up everything and go back to school, I will give a unified lecture on calculus .
I borrowed your books to see how sincere you are in studying, but now, in what capacity are you asking me for advice? "Ren Baqian felt that she had made a good excuse, after all, she was no longer a student of the academy, but a military advisor of a rebel army in Daxia.
You are not my student now, so naturally I will not answer your profound questions.
Well, this reason is not very good, but Ren Baqian couldn't think of a better reason for a while, and he didn't show his timidity.
Qing Lian froze for a moment, then pursed her lips and smiled. "It was my recklessness."
Then he smiled brightly, and made a request that has been calculated to be 87% likely to succeed: "In order to better communicate with Dayao, Sugong wants to send an envoy to Lancheng, and I want to deal with it completely." Just come to be this envoy for some things, and the governor must not refuse me to go back to study in the mansion."
Ren Baqian gasped in surprise, "Send an envoy? In what name?"
Su Gong is Su Qing, who established himself as Su Gong after the uprising. At this time, although the rebel army has reached the size of a million people, it is still a peasant rebel army after all. It is normal to want some help from Dayao, but it is more interesting to send envoys to Dayao.
"In the name of King Ping!" Qing Lian said with a slight smile.
Hearing this, Ren Baqian tapped lightly on the table with his fingers, thinking in his mind.
In the previous two battles between Daxia and Dayao, they almost lost all their vitality. Coupled with the excessive taxation by corrupt officials, and the Infernal Affairs dispatched by Su Qing, the people in many places are in dire straits.
From the very beginning, Su Qing revolted under the slogan "Equal rations!", but it swept a large number of people who were almost unable to survive. In addition, Da Xia was short of soldiers at the time, and it became a trend in a short period of time.
But although the elite soldiers of Great Xia were almost completely destroyed, there were still many fierce generals in the court. It took a year or two to train a group of soldiers who could fight. Although half of the country was lost, they gradually stabilized their positions. At that time, the two sides were in a state of tug-of-war, and I am afraid that it would be difficult to make a big breakthrough in a short period of time.
In this case, Su Qing wants to be king!
Ren Baqian thought for a while, and in a situation where it was difficult to enter the country in a short period of time, claiming the title of king was not the best way, but it could also have the effect of calming people's hearts.
If envoys are sent after being crowned king, it is still reasonable.
"As for more, I will talk about it when I meet His Highness in the afternoon." Qing Lian gave a slight bow.
Ren Baqian nodded, and in the afternoon, he had an audience as an envoy, and he was a public servant at that time.
And now, it is indeed a private visit.
It's a pity, what's the point of calculus
"I want to borrow a few more books to read. The governor will not refuse me, right? Just now the governor also said that I am very sincere in studying..." Qing Lian said, pulling her hair by her ear.
"Go!" Ren Baqian waved his hand.
"Take your plank away!"
"Let's leave this here. If I don't understand it when I come back in the future, I will wait for the governor to answer my questions when I return to the school!" Qing Lian bowed again before retreating.
Ren Baqian sat on the chair, looked at the symbol on the board, and felt that his brain and teeth began to ache.
After Qing Lian left for a long time, Ren Baqian went out with the plank in his hand, dug a hole, buried the plank inside, and finally felt a little better.
Sitting back in the office, Ren Baqian began to think.
Although Qing Lian had learned arithmetic before, she was at the junior high school level at most. When I came here, I systematically studied geometry and algebra in modern elementary and junior high schools. I didn't expect that I have learned calculus now...
No one taught her, she taught herself high school and college math...and got to a pretty high level.
This is another trick!
I have to admit that there are always some people in the world who are loved by heaven and earth.
For example, the empress Yu Wu Dao, for example, Ning Caichen is on the earth, for example, this Qinglian...
Um
Ren Baqian suddenly thought of something.
Ning Caichen and Qinglian
Know two sword masters yourself? All so talented? Is it too coincidental
The genius has been met by himself
Ren Baqian suddenly remembered what he had seen before. Thousands of years ago, there was a magnificent period, when thousands of sword masters were born and fought against each other, all of them left a lot of fame.
But that period was too long, and the records were vague, so he didn't think much about it.
And after that, the sword master was prohibited from entering the court as an official.
The reason is simple, the sword master needs a lot of resources to build the sword pool, so the possibility of corruption and bribery is too great!
Moreover, the sword master himself had to spend a lot of energy to buy rare treasures for his own life, and even searched for a long time in barren mountains and old forests.
Naturally, it gradually ceased to be noticeable.
However, after Ren Baqian had a little doubt in his heart at this time, he suddenly woke up with a question.
Thousands of years ago, how many god wheel fighters were famous and recorded in the history books? I'm afraid that even the disciples in his own sect may not know it.
Thousands of years, dozens of generations, is really too long.
But the lifespan of the sword master is not long, and there are very few people with the strength of the god wheel, and the number must be less than that of the warriors.
In this case, it is not only because of strength that he can leave a huge mark in history, right
Could it be that the sword master's skill point is crooked? Although he can't practice martial arts, his talent in other aspects far exceeds that of ordinary people? If so, it's a bit scary!
After seeing Ning Caichen and Qing Lian, Ren Baqian felt that this guess was not impossible, and it might be very big.
