As soon as Tang Sufan took a sip of water, he almost spurted it out again.
The choking made Tang Sufan cough repeatedly, and the pretty boy's face turned red from the choking.
"Cough cough cough cough..."
He finally recovered and quickly waved his hand to cover up his embarrassment.
"It's okay, it's okay, the water is too hot..."
Good guy, he is worthy of being a ruthless man who is almost considered a god by later generations. This ability is really mysterious!
Jade Broken Ningshuang, doesn't it mean that his predecessor has been sacrificed to heaven?
And what is behind the mysterious thing, isn't it just that I have traveled through time?
Good guy, can you figure this out?
He is worthy of being a famous old magic stick in Chinese history. He is so accurate~
Looking at Tang Sufan's sudden embarrassment, Yuan Tiangang, who had no results, said with some shame: "My dear, please forgive me..."
"Where is it, Taoist Yuan, cough, cough, cough. Actually, I already know it in my heart. I just want to borrow someone else's hand to see if I am blind..."
Yuan Tiangang looked sideways for a moment...
It turns out that this kid is just testing his ability?
Yes, if you can calculate the evolution of heaven's secrets and have no fear of the secrets not being leaked, how can you not be able to save yourself?
People of a certain level talk to people of a certain level. It turns out that the kid is really testing his own abilities.
This makes sense, understand, understand...
Afterwards, Tang Sufan quickly skipped this topic.
Who can guess whether this old man will be able to figure out his identity as a time traveler.
After all, this old man is really mysterious~
And I don’t want to be an outlier~
Isn't it beautiful to pretend to be a fool and fool around when nothing is wrong?
In just three or five cups of tea, Yuan Tiangang had a lively conversation with Tang Sufan.
In the sky and on the earth, there are four seasons.
Despite Yuan Tiangang's many years of travel, Tang Sufan was still able to catch the conversation.
Although sometimes he is wrong, he still misleads Yuan Tiangang~
Tang Sufan also felt a little guilty. Good guy, luckily I was a little white dragon on the Internet back then and was a good student in the nine-year compulsory education in a high-quality country.
And there is a lot of traveling around, otherwise if you were an otaku traveling through time, you really wouldn’t be able to deal with this old man.
Even Li Chunfeng couldn't help but get up and come in to say a few words, but Tang Sufan pretended to be smooth...
When it came to astronomy, Tang Sufan even described the two of them as confused as a student...
It's like opening the door to a new world...
"teacher?"
At this time, the boy Li Chongyi came out.
He walked in with a piece of question paper in his hand and looked a little ashamed.
"What's wrong?"
Li Chongyi took a look, scratched his head, and then prepared to leave.
"The student is confused about this question, and I came here to ask for advice. However, the gentleman is still waiting for guests, so we should wait a while."
Tang Sufan looked anxious and quickly grabbed his eldest disciple.
"Well, the reason why a teacher teaches is to teach and solve doubts. If the students have problems, how can the teacher be slack? Even if there are guests, so what, as a teacher, I will first answer your doubts..."
Good disciple, you came at the right time.
Although Yuan Tiangang and Li Chunfeng are famous magic sticks in history.
But chatting with these two people was really stressful.
How to spend it?
Isn't this opportunity coming?
My students have come to ask me for advice. You two must be a little discerning.
Why don't you hurry up and say goodbye?
Although I can’t bear to leave this forest fairy who is more eye-catching than the flowers sitting there, I can’t bear to continue chatting~
"Daozhang Yuan, I..."
Tang Sufan spread his hands, showing that he had no choice but to teach the students.
Why don't you go back quickly? Didn’t you see it’s already dinner time? You can't be as shameless as that dog emperor, right?
But Yuan Tiangang and the other two just smiled.
"My friend, please excuse me. I and I are lucky enough to be able to meet my little friend as a disciple. It is also fate..."
Then act like I will stay here and wait for you.
To be honest, Yuan Tiangang and Li Chunfeng were addicted to chatting.
This Tang Sufan, I don’t know where he came from.
Whether we were chatting with him about astronomy and calendar, or the changes in the four seasons, he knew it all.
It can be said that as he said, the world is huge, but it is just like the stars in the sky, just a ethereal thing in the universe.
For the two masters of astronomy and calendaring in this era, it is nothing more than enlightening remarks.
It was obvious that the two masters and apprentices were having a good time chatting.
Even Lin Xueyan and the young lady were attracted by Tang Sufan's conversation just now...
Tang Sufan's mouth twitched. Are all people in the Tang Dynasty so thick-skinned?
I can hardly continue the conversation without looking at the young master, why are you just hanging here?
Forget it, find another way to kill these two people.
I took the question paper and glanced at it, math question? Or a geometric math problem?
"Chongyi, do you still remember the age unit I asked you to memorize before?"
Li Chongyi nodded respectfully: "Students remember."
"Look at the title, a cup of rice in a Gusu farmer's house is three feet wide, one foot narrow, and two and a half feet wide..."
This question is nothing more than a question about the area of a regular trapezoid.
It can be written like this because Tang Sufan changed it like this in order to fit the background of the times.
"First of all, you have to clearly distinguish what is length and what is width. Different from the rectangle I taught you before, this is a trapezoid, and the trapezoid is divided into..."
When Tang Sufan lectured slowly, everyone except the obedient student Li Chongyi listened carefully.
Even Yuan Tiangang and Li Chunfeng were spellbound for a moment...
Such a theory? Never heard of it?
Could it be that this is the science of the Immortal Sect?
Especially Li Chunfeng, what a good guy, his eyes are almost shining.
Listening to Tang Sufan's remarks secretly, I hated myself for not bringing a pen and paper.
After learning in this way, I should write it down secretly!
When Li Chongyi suddenly realized it and stayed in a trance, he listened briefly.
Just go down and do the questions by yourself.
"May I ask that what Brother Tang just talked about is also about numerology?"
As soon as Li Chongyi left, Li Chunfeng asked quickly with eyes shining.
This question is related to numeracy, but it seems to have nothing to do with numeracy...
"That's right, this is a category of geometry in the art of mathematics."
Is there such a category in numerology?
"Ahem, Brother Tang is really a great talent, but a poor man... I have a few questions on numerology, and I would like to discuss them with Brother Tang. Is it convenient?"
"inconvenient!"
Tang Sufan did not hesitate and refused with a wave of his hand.
It's noisy.
I was a liberal arts student back then, so if you want me to fool you, that’s fine.
Mathematics was a nightmare back then.
The only subject I was partial to in high school was mathematics.
At that time, I was so exhausted in college that I lost my hair for several months and barely managed to get enough credits to pass.
Even now, he has already forgotten about 90% of the time. He has no confidence in showing off mathematics.
If I don’t pretend to be mellow, it won’t be in line with my personality...
Li Chunfeng's expression reminded him inexplicably of the math instructor in college who had a forehead like growth rings and a pair of bulletproof glasses.
Huh……
Just thinking about it makes me irritated...
"Forehead……"
Li Chunfeng's expression froze...
Recently, he was deducing the astronomical calendar, which involved several advanced mathematical methods. He had been stuck for several days and made no progress for several days.
Now this is a great opportunity.
I still want to be a little clever...
As a result, every knowledge in the Taoist sect is a secret that is not passed down.
Secondly, since my husband is still sitting here, I have no choice but to be clever.
As expected of a disciple of the Immortal Sect, he can see through it at a glance...
But Li Chunfeng is really itchy...
The question just now seems simple, but the mathematical logic designed in it is unheard of!
How could someone who is not a master of numerology have designed it?
The most important thing is that they are used to teach children!
But if I miss it now, I may not have the opportunity in the future...
For a moment, Li Chunfeng was confused...
Li Chunfeng still didn't give up and asked with a smile: "Well, I'm just talking about discussion. I'd like to ask Brother Tang to give me some advice."
Now that the words have been said, Tang Sufan can only show his hands and show his cards...
"Ahem, Brother Li... I must have misunderstood you. I'm really not good at math. I can teach children just fine, but I'm far different from people like you who are math, science and astronomy..."
"I think back then, I didn't even pass advanced mathematics or calculus, so I had to retake it to get the credits. Back then, even a quadratic equation or an advanced function in four variables would make people go crazy..."
Alas, thinking about it brings tears of bitterness...
Tang Sufan felt that he couldn't let this guy misunderstand.
This will make him feel that he is a master of mathematics, and then his courtyard will be more lively in the future...
Li Chunfeng's mouth twitched, and his whole body felt bad.
It's like watching a person standing on a high mountain say humbly to the people below: Alas, this is too low...
Is this what the Immortal Sect disciples have in mind? It’s beyond my generation’s reach...
Even those advanced numbers...calculus...and those quadratic equations, advanced functions...
He has never heard of it...
Could this be the rumored immortality?
Looking at the back of Li Chongyi who had just left the house, Li Chunfeng's eyes showed envy. The opportunities between this person and others are really different...
At this age, people can listen to the teachings of immortality.
"Brother Tang, are you serious about this?"
It was so mysterious that Li Chunfeng couldn't help but confirm it subconsciously.
Believe it?
Tang Sufan took a look and felt greatly relieved. It was really great. This guy believed that he was a novice in mathematics.
This is called "preventing future troubles". I am really smart.
He nodded repeatedly: "That's right, that's right. Alas, this aspect of mathematics is full of bitter tears..."
As soon as Tang Sufan said this bitter tone, Li Chunfeng ignored Yuan Tiangang and was still sitting there.
"Li Chunfeng, a junior student, please give me some advice!"
Li Chunfeng looked excited and bowed his hands.
Tang Sufan and Yuan Tiangang's lips twitched at the same time.
Can you still play like this?
And Tang Sufan was even more speechless.
What, you can’t understand people?
Haven't I repeatedly emphasized to you that I am a noob at mathematics?
Why are you so stubborn, kid?
If it were anyone else, Tang Sufan would have run away a long time ago, but this person was still a magic stick, and a famous stick man in Chinese history.
If someone wants to take revenge on me, with the mysterious abilities of people like them, I will be confused if I get punished...
You said that you are a land god in the eyes of future generations, do we have some status?
Yuan Tiangang is also trying to catch someone blind. This kid has made himself very embarrassed...
But who could let the child's professional ability be better than that of his original wife, the teacher?
Moreover, he and Li Chunfeng are not considered to be the same masters and disciples, so it is not impossible for others to ask for advice...
At this time, Yuan Tiangang could only smile bitterly and said: "Tang Xiaoyou, Lao Dao is a student who is obsessed with mathematics. Now he may not have encountered a difficult problem, otherwise he would not have said this... If... Tang Xiaoyou has no concern, That’s it…”
Tang Sufan glanced over speechlessly.
Old man, this is me, the CPU...
What you said is quite good.
It's not enough if I don't teach...
Forget it, these two big guys can’t be offended.
Let's take a look first. If it doesn't work, just give it up. I won't do it and you won't force me anymore.
You said it's a difficult problem.
At this point, Tang Sufan could only hold his nose and recognize it.
"Okay, Brother Li, why don't you write it down and let me take a look. But please let me know in advance, please don't blame me if I can't solve Brother Li's question..."
"Xiaodao doesn't dare."
Seeing that he had agreed, Li Chunfeng borrowed pen and ink from Tang Sufan and wrote quickly.
"Please sir, take a look."
Li Chunfeng handed the paper to Tang Sufan respectfully, without even noticing Yuan Tiangang, who looked unhappy next to him.
"Okay, let me take a look. Brother Li, please stop standing and sit down..."
Tang Sufan was not used to it when he saw that Li Chunfeng was really looking at him respectfully.
Boss, can’t you talk nicely?
Your sudden admiration makes me feel even more guilty.
Li Chunfeng refused to sit down, saying that this was the etiquette for asking for advice.
Tang Sufan:......
Tang Sufan glanced at it with a guilty conscience. After looking at it for a while, his waist slowly straightened up unconsciously.
It turns out to be just a few related three-dimensional quadratic equations?
If you want to say this, I think I can still be rescued, and I can still use it for another wave.
I thought that you, who deduced the calendar, reset the armillary sphere, and wrote the "Tui Bei Tu" with your teacher, would ask some historical questions, but this is it.
If I didn’t know how to do this, my high school teacher would be so angry that he would hit me on the head with two teacups~
"Ahem..."
Tang Sufan coughed lightly, and Li Chunfeng quickly looked nervously.
"Now that Daochang Yuan has spoken, I must give Daochang Yuan some face. Even a kid can solve this question. That's all. Let me solve it for you..."
This situation of giving favors must be handled well.
Didn't anyone look at Yuan Tiangang, even the immortal Taoist priest, with a look of relief on his face?
This is emotional intelligence.
Alas, you are worthy of being a disciple of the Immortal Sect. Look at others, and then look at you.
Yuan Tiangang glanced at the half-disciple who was "licking a dog" angrily, as if he kicked him.
What did I bring you here to draw today?
He asked his apprentice to bring him his pen. The pen was elegant and graceful, and then he handed it to Li Chunfeng confidently.
"Come on, Brother Li, let's see if it's right."
Li Chunfeng was careful about the result, and kept tinkering in his mouth as if reciting mantras, and his eyes almost looked into it.
Afterwards, Li Chunfeng's face suddenly looked like he was relieved, and he quickly held up his hands in admiration: "If you give me more advice, sir, your calculations will definitely be correct! The student deduced it three times in reverse, and there is nothing wrong. I would like to thank you more for your advice!"
"No, no, no, forget it, sir. Brother Li, it would be more pleasant to call me Brother Tang. I just did it casually. I was lucky enough to figure it out. I don't deserve this sir~"
He has a mellow temperament, alas, I've pretended to do it again.
