Huang Xinghe saw from a distance that little kid was walking towards him step by step, looking at his short arms and short legs, he seemed to be majestic and arrogant, he wanted to step forward quickly, pick him up, and beat him up fiercely, so he was happy!

However, he knew that he couldn't, because he was now a gentleman.

Be a teacher, and be a model.

He wants to convince people with virtue!

However, in the face of technology, who can Germany serve?

Huang Xinghe felt extremely weak and bitter when he thought about it.

"Sir, did you calculate that problem yesterday?"

Yang Jian felt blushing when he heard his voice, slush, soft, glutinous, could it be that his voice expression had changed after the crossing?

Just like last night, if he hadn't tried his best to restrain himself every time and try his best to use the performance he had learned in school to express his opinions, he would probably be knocked off the stage by those rough men and girls in the conference hall, but fortunately, thanks to Grandpa and Father Qin, he finally persevered.

"Little brother, hello!"

Huang Xinghe looked at him left and right and expressed his morning greetings.

"Sir, my brother asked you if you did the problem you solved yesterday?"

Xu Hezi must also be a harmful reincarnation, knowing that Mr. is deliberately avoiding answering, but he still wants that foot to step on painfully, for such a girl, who will Mr. punish if you don't punish you?

Yang Jian looked at Huang Xinghe with the same smile as Xu Hezi, with a gentle and harmless smile.

"Xu Hezi, you go in first and read the three-character scripture ten times with your classmates!"

Huang Xinghe glared at Xu Hezi, who was talkative.

"Well, sir—"

Xu Hezi glanced at his brother reluctantly and went in obediently.

"Sir, you won't be embarrassed by Xu Kazuko, will you?"

Yang Jian asked a little worriedly.

"Why should I be embarrassed by Xu Kazuko?"

Huang Xinghe was a little strange about the way of thinking of the child in front of him.

"Because I've embarrassed you, sir?"

Yang Jian doesn't like to hide it.

"Ho-ho-ho, you're really a villain-" Huang Xinghe gasped and continued, "Do you think I look like such a petty gentleman?" ”

"Not really."

Yang Jian replied quickly to Huang Xinghe.

Sometimes it's easier to convince people by praising them than by scolding.

He's not eight, he's not nine, he's twenty-five, okay?

"Come here—"

After Huang Xinghe finished speaking, he turned around and walked towards another small room in the ancestral hall.

Yang Jian looked at Huang Xinghe's hurried appearance, knowing that he wanted to talk to him alone, but without thinking about it at the moment, he took a step away and followed Huang Xinghe all the way.

"Tell me, who gave you that question yesterday?"

Huang Xinghe walked to the small room and looked around, no one should be eavesdropping, as if he was relieved.

This small room should be his bedroom in this private school, although it is simple, but it is also clean, a bed, a chair, a desk, a bookshelf, and a few simple washing items.

Nothing else.

However, it is indescribably comfortable to watch.

Yang Jian likes it.

Perhaps this is the ancestor of later generations of minimalism or frivolity decoration style?

"I gave it to you myself, sir?"

Yang Jian looked at Huang Xinghe, his eyes were not confused at all.

"Are you sure?"

Huang Xinghe looked at the harmless face of the child in front of him, how did he not look like a child who could do arithmetic? What's more, there is such a huge and complex arithmetic problem?

Could it be that he just happened to play tricks on his random questions?

"Of course, sir."

Yang Jian nodded vigorously, proud and pure.

"Then tell me what the answer to yesterday's question was?"

Huang Xinghe felt that if he just came out casually, then he would definitely not know the answer.

"But, sir, is this the question I gave you?"

Yang Jian was unconvinced.

Great dissatisfaction!

"Hehe, sir, you're sure that you just came out to spoof Mr., in fact, you don't know what the answer is, right?"

Huang Xinghe finally found a reason for himself, and was happy for this reason, and the huge mountain rock in his heart broke free at once, and he was also relieved.

"Sir, it's wrong for you to do this, I can tell you the answer, but if I tell you the answer, you have to accept my other question, so that it is fair, what do you think?"

Yang Jian is not a vegetarian either, he knows that Huang Xinghe just wants to blackmail himself.

"Okay, will you show me?"

When Huang Xinghe heard this, his heart was happy again.

He wanted to see how the doll-like little broken child who jumped out of the New Year's painting in front of him could be calculated.

"The answer is five hundred thousand and five hundred, sir!"

Yang Jian already had a plan in his heart.

Such a simple problem of summation of the difference series, when he was in his third year of high school, it was very commonplace, and this problem was adapted by him from the story of the great mathematician Gauss when he was a child.

For modern people, an ordinary high school student can easily solve it, but for the ancients, hehe, if you don't grind off a few layers of his skin, I'm afraid you can't think of an answer, you have to rely on your fingers and arithmetic and mental arithmetic to add one by one, that requires extremely strong mental power to support it, and it will torture people crazy!

"Five hundred thousand and five hundred?"

Huang Xinghe sighed in his heart.

He looked at the little broken child in front of him stupidly, five hundred thousand and five hundred? How did he do it? He barely saw his fingers and mouth move, and then he figured out the answer?

Answer?

Oh my God, is this little kid in front of you a human or a ghost?

Since he came back from the doctor's house last night, this question has made the first person in arithmetic in the Tang Empire, the current third highness, the doctor's most proud assistant and the most proud protégé all sighed for a day without calculating it, and he calculated it all at once?

Don't believe it, this guy must have come prepared, I don't know how many times I've been calculating at home, so I'm specifically using this topic to test myself?

It must be like this, if you give yourself enough time, you can figure it out yourself, right?

Huang Xinghe's self-confidence and questioning spirit have become proactive again.

"Yes, sir, do you believe it now?"

Yang Jian was triumphant, and her proud expression was like a little rooster who had won a fight over a little hen.

"Sir still doesn't believe me."

Huang Xinghe smiled and shook his head, saying.

"Still don't believe me?"

Yang Jian's eyes widened, he felt that he was about to be defeated by the old man in front of him!

"Yes, you've been secretly doing this for a long time, aren't you?"

Huang Xinghe's guess is nine out of ten.

I finally breathed a sigh of relief for the depression I had had all day before, and the depression was swept away.

"Of course not, if you don't believe you, sir, we can compare, let's come up with the same question again to compare who is faster?"

Yang Jian's pride was also stimulated.

"One more?"

Huang Xinghe was surprised and delighted by this challenge.

"That's right, one more one, sir, you have a question!"

Yang Jian is very generous.

"Really?"

"Of course!"

"Then you are not allowed to cheat, I will ask the question, and if you answer slowly, you will lose, okay?"

"Deal!"

"Deal!"

Huang Xinghe was very happy, his competitiveness was also completely stimulated, and he also buried a little Jiujiu for himself, if he came up with another question, if Yang Jian didn't calculate it, or rather, he didn't calculate it before himself, he would win.

Where to find such a profit-only and non-losing deal?

"Sir, please ask!"

Yang Jian stretched out a white and tender little hand and made a gesture of invitation to Huang Xinghe.

"Good!"

Huang Xinghe was made to cry and laugh by the little kid in front of him.

"I'll listen, sir."

Yang Jian's face was calm and calm.

"Okay, may I ask Yang Jianxiao, what is the number from 1 to 100?"

After Huang Xinghe finished speaking, he looked at Yang Jian triumphantly.

"Huh?"

Yang Jian almost choked to death by a mouthful of his own saliva.

Is Huang Xinghe the reincarnation of the legendary Gauss teacher after a thousand years? So, without thinking, he came up with an identical topic for himself?

"How's it going, little friend?"

Huang Xinghe actually couldn't figure it out himself, and he didn't plan to count it anyway.

According to the rules, as long as Yang Jian answers incorrectly, he wins.

And he calculated that Yang Jian would not win.

"Mr. Hui, the number is five thousand and fifty!"

Yang Jian smiled happily and charmingly, his small white teeth shining in the winter sun.

"You? Are you sure? ”

Huang Xinghe was a little unconvinced.

This guy must be guessing randomly, so come to fool himself?

It's likely that the answer above is also his nonsense, right?

Huang Xinghe looked at Yang Jian, and the activities in his heart were like turning over the river and the sea, and the clouds and rain turned upside down.

"Of course, don't you believe me?"

Yang Jian looked at Huang Xinghe, who was angry and had a green face, and smiled like a little warm man.

"Nope! Letter! ”

Huang Xinghe almost gritted his teeth and popped out two words.

"Yes, sir, I'll prove it to you!"

Yang Jian was not in a hurry at all, pulled Huang Xinghe to sit down on his crumbling solid wood chair, and then, found a wooden stick, touched the ground on one knee, and planned to personally demonstrate Huang Xinghe's calculus-
