The first free king of Tang Dynasty

Chapter 520 I'm Really Bad at Math
As soon as he took a sip of water, Tang Sufan almost spit it out again.

Tang Sufan was so choked that he coughed again and again, and that little boy's face turned red from choking.

"Cough cough cough..."

After finally slowing down, he quickly waved his hands to cover up his embarrassment.

"It's okay, the water is too hot..."

Good guy, he deserves to be a ruthless person who is almost passed down to be a god figure by later generations. This ability is really mysterious!
Doesn't Yusha Ningshuang mean that his predecessor has already sacrificed to the sky?
And what is the mysterious and mysterious stuff behind it, isn't it just that he has traveled through time?
Guys, can this be figured out?

It is indeed a famous old magic stick in the history of China, it is really accurate~

Seeing Tang Sufan's sudden embarrassment, Yuan Tiangang, who had no results, said with some shame, "My little friend, please forgive me..."

"Where is there, Daoist Yuan, cough cough cough, in fact, I already know it, the boy just wants to use the hands of others to see if the boy is blind..."

Yuan Tiangang looked sideways for a moment...

So this little friend was just testing his abilities?

Yes, if you can calculate the evolution of the secrets, and you are not afraid of the way that the secrets cannot be revealed, how can you not pass yourself?
What level of people talk to what level of people, it turns out that Xiaoyou is really examining his own ability.

That makes sense, understands, understands...

Afterwards, Tang Sufan quickly skipped over this topic.

Whoever guesses this old man will calculate whether he 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~
It's okay, isn't it beautiful to play tricks and play tricks?
In just three or five cups of tea, Yuan Tiangang had a lively conversation with Tang Sufan.

Heaven and earth, four seasons and five constants.

No matter how much Yuan Tiangang has traveled for many years, Tang Sufan can still catch up with the conversation.

Although sometimes the bull's head is wrong with the horse's mouth, it still confuses Yuan Tiangang's chat~

Tang Sufan also felt a little guilty, good guy, but luckily I was a little white dragon of the Internet back then, a good student of the high-quality national nine-year compulsory education.

And there are a lot of travels, otherwise, if an otaku travels through time, he really can't deal with this old man.

Even Li Chunfeng couldn't help but come in and interject a few words, but Tang Sufan pretended to be mellow...

And when it came to astronomy, Tang Sufan made the two of them confused like a student...

It's like opening a door to a new world...

"teacher?"

At this time, Li Chongyi jumped out.

Still holding a question paper in his hand, he walked in with a somewhat ashamed expression.

"What's wrong?"

Li Chongyi took a look, scratched his head, and was about to leave immediately.

"The students are confused about this question, so I came here to ask for advice, but the master is still entertaining guests, so let's wait a while."

Tang Sufan's face became anxious, and he quickly grabbed his eldest apprentice.

"Hey, the reason why the teacher preaches and accepts karma to solve doubts. If the students have problems, how can the teacher slack off? Even if there are guests, so what, as a teacher, I will first solve your doubts..."

Good apprentice, it's really time to come.

Although Yuan Tiangang and Li Chunfeng are famous magic sticks in history.

But chatting with these two people is really a bit stressful.

How to send it away?
Isn't this an opportunity?
My students have come to ask me for advice, you two should have a little insight.

Why don't you hurry up and say goodbye?

Although I can't bear to part with this fairy Lin who sits there and is more eye-catching than flowers, but I can't bear to talk any more~

"Daoist Yuan, I..."

Tang Sufan spread his hands, showing that he had no choice but to teach the students.

Why don't you go back soon?Didn't you see it's time for dinner?You can't be as cheeky as that dog emperor, can you?
But Yuan Tiangang and the two just smiled.

"Your friend, please go ahead, the two of you are just lucky enough to see you as an apprentice, it is also fate..."

Then 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 it is chatting with him about astronomy and calendar, or the changing seasons, he knows it all.

It can be said that what he said, the world is as big as the stars in the sky, just a ethereal thing in this universe.

As for the two masters of astronomy and calendar in this era, it is tantamount to enlightening remarks.

Obviously, the two masters and apprentices are having a good chat.

Even Lin Xueyan and the young lady were attracted by Tang Sufan's chat just now...

The corner of Tang Sufan's mouth twitched. Could it be that everyone in the Tang Dynasty was so thick-skinned?
I can't talk anymore without looking at the young master, so why don't you just stay here?
Forget it, let's get rid of these two in another way.

He took the question paper and glanced at it, math problem?Or a geometry math problem?

"Chongyi, do you still remember the age unit that you were told to memorize earlier?"

Li Chongyi nodded respectfully: "Student remember."

"Look at the question, a cup of millet from a millet farmer's family, the mouth is three feet deep, the mouth is one foot narrower, and the mouth is two and a half feet wide..."

This question is nothing more than a question about the area of ​​a trapezoid.

It can be written like this, not because Tang Sufan changed it like this to fit the background of the times.

"First of all, you have to distinguish clearly what is long and what is wide. Unlike the rectangle I taught you before, this is a trapezoid, and the trapezoid is divided into..."

When Tang Sufan was lecturing slowly, except for that obedient student, Li Chongyi, who listened carefully.

Even Yuan Tiangang and Li Chunfeng were fascinated for a while...

Such a theory?Never heard of it?
Could it be that this is the science of the fairy gate?
Especially Li Chunfeng, good guy, his eyes are almost shining.

Listening to Tang Sufan's remarks in his heart, he hated himself for not bringing a pen and paper.

Such a learning, I should secretly write it down!
When Li Chongyi suddenly realized and stayed in a trance, he got a rough idea.

Just go down and do the questions obediently.

"Dare to ask that what brother Tang just talked about is also a math technique?"

As soon as Li Chongyi left, Li Chunfeng hurriedly asked with bright eyes.

This question is related to numerology, but it seems to have nothing to do with numerology...

"That's right, this is a category of geometry among numerology."

Does numerology still have this category?
"Cough cough, brother Tang is really a great talent. I'm poor... I have a few questions about numerology. I want to discuss with brother Tang. Is it convenient?"

"inconvenient!"

Tang Sufan refused without hesitation.

What a mess.

I was a liberal arts student back then, so if you want to fool me, that's fine.

Mathematics, that was the nightmare of the year.

The only subject I was partial to in high school was mathematics.

At that time, the university was a waste of nine bulls and two tigers. After losing the strength of hair for several months, I barely got enough credits.

Even now, he has already forgotten seven out of ten things, and he has no confidence in pretending to be math.

If you don't pretend to be mellow, it doesn't fit my personality...

Li Chunfeng's expression reminded him inexplicably of the mathematics instructor who had a forehead like an annual ring and a pair of glasses that could prevent bullets in the university.

what……

Just thinking about it will infiltrate people...

"Forehead……"

Li Chunfeng's expression froze...

Recently, he was deducing the astronomical calendar, which involved several advanced mathematical techniques. He had been struggling for several days, and he hadn't made any progress for several days.

Now this is a great opportunity.

I still want to be a little smart...

As a result, the knowledge in every Taoist sect is a secret that is not passed on.

Secondly, my husband is still sitting here, I have no choice but to be clever.

As expected of a disciple of Xianmen, you 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 it be possible to design it if it wasn't someone who possesses the principles of numerology?

The most important thing is that they are used to teach children!
But if you miss the present, you may not have a chance in the future...

For a while, Li Chunfeng was tangled...

Li Chunfeng still didn't give up, and asked with a smile: "Well, it's only about the competition, and I would like to ask brother Tang to teach me a thing or two."

It's all said here, Tang Sufan can only have a showdown...

"Cough cough, brother Li... I think you have misunderstood me. I really can't do math together. It's okay to teach children, but it's far from someone like you..."

"I think back then, I didn't even pass advanced mathematics and calculus, and I got the credits only after retaking it. Back then, a quaternary quadratic equation or advanced function, I could see it directly..."

Alas, just thinking about it brings bitter tears...

Tang Sufan felt that this fellow should not be misunderstood.

If this makes him feel that he is a master of mathematics, then the dragon robe in his yard will be much more lively in the future...

The corner of Li Chunfeng's mouth twitched, and he was in a bad mood.

It's like watching a person standing on a high mountain say to the people below with humility: Oh, this is too low...

Is this the heart of the disciples of Xianmen?I can't reach it...

Even those high numbers...calculus...and those quaternary quadratic equations, advanced functions...

He has never heard of it...

Could this be the rumored fairy school?
Looking at the back of Li Chongyi who had just left the house, Li Chunfeng's eyes showed envy. The chances of this person are really different...

At this age, people can listen to immortal studies.

"Brother Tang, are you serious?"

What he said was so mysterious, Li Chunfeng couldn't help subconsciously confirming it.

Believe it?

Tang Sufan glanced at it, feeling relieved, it's really great, this guy believes that he is a math rookie.

This is called "to avoid future troubles", I am really smart.

Nodding again and again: "That's right, that's right, alas, this math aspect is full of bitter tears..."

As soon as Tang Sufan's bitter tone came out, Li Chunfeng ignored Yuan Tiangang and was still sitting there.

"Li Chunfeng, a late student, please give me your advice, sir!"

Then Li Chunfeng looked excited, and directly saluted.

The corners of Tang Sufan's and Yuan Tiangang's mouths twitched at the same time.

Can you still play like that?
And Tang Sufan was speechless.

What's wrong, you can't understand people's language?

Didn't I repeatedly emphasize to you that I am a math rookie?
Why are you so stubborn, kid?

If it were someone else, Tang Sufan would have run away long ago, but this person is still a magic stick, a well-known magic stick in Chinese history.

If people want to take revenge on themselves, with their mysterious abilities, they will be stupefied...

You said that you are a land god in the eyes of future generations, do we have a bit of status?
Yuan Tiangang is also caught blind, this kid, let yourself lose face...

But who would let other children's professional skills be better than their original teacher?

Moreover, he and Li Chunfeng are not regarded as masters and apprentices of the orthodox school, and it is not impossible for people to ask for advice...

At this time, Yuan Tiangang could only smile wryly and said: "Xiaoyou Tang, this old Taoist student is obsessed with numerology. I'm afraid he has encountered a difficult problem now, otherwise he wouldn't have opened his mouth... If... Xiaoyou Tang, what considerations do you have? That's fine..."

Tang Sufan glanced over almost speechlessly.

Old man, you are my CPU...

What you said is level.

Let me not teach it is not enough...

Forget it, these two big guys can't be messed with.

Let's take a look first, if it doesn't work, just drop the pick, I won't, you won't force me anymore.

You said it was a problem.

So far, Tang Sufan could only pinch his nose and admit it.

"Okay, Brother Li, why don't you write it down and let me take a look, but let me state in advance, if you can't solve Brother Li's problem, please don't blame..."

"Xiaodao dare not."

Seeing that he agreed, Li Chunfeng borrowed pen and ink from Tang Sufan, and wrote it quickly.

"Please take a look, sir."

Li Chunfeng handed the paper to Tang Sufan respectfully, and didn't see Yuan Tiangang next to him with a sulky face.

"Okay, let me take a look, Brother Li, stop standing, sit down..."

Tang Sufan was not used to seeing Li Chunfeng really respectfully waiting.

Boss, can't you talk nicely?
Your sudden admiration made me even more guilty.

Li Chunfeng insisted not to sit down, saying that this is the courtesy to ask for advice.

Tang Sufan: ...

Tang Sufan glanced at it with some guilt, and after looking at it for a while, his waist slowly straightened.

It turned out to be just a few related ternary quadratic equations?

If you want to say this, then I think I can still be rescued, and I can use it to install another wave.

I thought you, a big guy who deduced the calendar, reset the armillary sphere, and wrote "Tui Bei Tu" with his teacher, would ask some historical questions, so that's it.

If I still don't know how to do this, my high school teacher will be so angry that I will hit my forehead with two teacups~
"Cough cough..."

Tang Sufan coughed lightly, and Li Chunfeng looked nervously.

"Since Daoist Yuan has spoken, I must give Daoist Yuan a face. This question can be solved by a kid, that's all, let me solve it for you..."

This situation of giving favors must be handled properly.

Didn't Yuan Tiangang, who didn't look at other people even if he was a fairy, looked relieved?

This is emotional intelligence.

Alas, as expected of a disciple of the Immortal Sect, take a look at others, and then look at you.

Yuan Tiangang glanced angrily at half of the apprentice in the "dog licking" posture, as if kicking him.

What are you drawing here today?

Asking his apprentice to bring his own pen, the pen was flamboyant, and then confidently handed it to Li Chunfeng.

"Come on Brother Li, let's see if you are right."

Li Chunfeng was careful as a result, his mouth kept fiddling as if reciting formulas, and his eyes almost followed him.

Afterwards, Li Chunfeng's face suddenly seemed relieved, and he quickly cupped his hands in admiration: "More guidance from the gentleman, the calculation of the gentleman is sure to be correct! The student deduced it three times in reverse, and there is no mistake. Please give more guidance to the gentleman!"

"Don't don't don't, sir, it's fine. Brother Li still told me Brother Tang to be more pleasing to the ear. I just did it easily. I was lucky enough to solve it. This sir, I can't be it~"

The temperament is mellow, alas, I pretended it again.
