Li Yan looked at Huang Xinghe, frowning, looking innocent, but also feeling excited and shocked.

"Your friend gave you another question?"

Li Yan looked at Huang Xinghe as soon as he entered the door, and knew that he must be in trouble again.

"Uh-huh."

Huang Xinghe nodded, his eyes were dead ash.

"That problem solved last time?"

Li Yan looked at Huang Xinghe.

He has been thinking and meditating on the problem last night until now, and he has not found any better way to solve it.

And now, Huang Xinghe told himself, that guy sent him another surprise?

"Uh-huh."

Huang Xinghe nodded vigorously again.

"Did you figure it out yourself?"

Li Yan looked at Huang Xinghe and felt incredible, it was solved after only one night?

"No, no."

Huang Xinghe's face was depressed, and he felt that he had no face to see his master again.

"Did he tell you the solution?"

Li Yan still thinks it's incredible, because he is so tricky that he wants to die, how can there be a living person in this world who can answer?

"Yes, sir."

Huang Xinghe knew that Li Yan must be as shocked as he was now.

"Tell me about it?"

Li Yan was shocked, but curiosity took over.

He didn't have the heart to be depressed right now.

His fascination with mathematics has always made him a more open-minded person than the average person.

"That's ........."

Huang Xinghe took out a pen from Li Yan's desk, put it on a piece of paper, and calculated it in front of Li Yan according to Yang Jian's way of solving the problem.

"Really...... Simple. ”

After Li Yan listened, he sat down on the yellow rosewood Taishi chair.

"Indeed, sir, this guy has discovered the pattern behind the numbers."

Huang Xinghe has completely lost yesterday's doubts and disbelief today, and he can only admire now, admiring the eyes that can find the laws behind the complicated appearances.

Moreover, what shocked him even more was that the guy also told himself a formula, saying that all such topics in the future can be calculated like this, and it is guaranteed to be fast and accurate!

"Fast and accurate?"

Li Yan repeated Huang Xinghe's words, and he used a few simple numbers to test.

As a result, it really is.

"The students are really ashamed of their shame."

Huang Xinghe stood there stupidly, his face as pale as paper.

All the pride accumulated in his previous life was broken by a child who suddenly appeared in this way, and his pride was defeated.

"Xinghe, don't say that, according to what you say, you are ashamed to be a teacher. However, you must remember that there are people outside the world, and there are heavens outside the sky, and we must always be in awe of learning, and it is more important for us to grow and progress with humility. ”

Li Yan looked at the dejected Huang Xinghe and comforted.

It is also a comfort to yourself.

"Disciple keep it in mind, sir."

Huang Xinghe took a deep breath and gave Li Yan a deep squeeze.

"What kind of topic did this friend of yours bring you today?"

Li Yan took the initiative to ask now, he knew that the purpose of Huang Xinghe's appearance here must have something to do with it.

Moreover, he is also very curious about this friend of his now.

"Sir, here's the title."

Huang Xinghe respectfully handed over the question written by Yang Jian.

"This ————"

As soon as Li Yan saw the piece of paper handed over by Huang Xinghe, his palms trembled, and he almost flew out of his hand.

"My friend's handwriting is indeed a bit unsatisfactory, sir."

Huang Xinghe also felt very embarrassed, looking at the chicken feet text on the paper, he didn't dare to look at his husband's eyes.

"Ho-ho, interesting-"

Li Yan also laughed.

"Sir, this question—"

Huang Xinghe looked at the smile on Li Yan's face, and suddenly felt a little more optimistic in his heart.

"Huh? I haven't had time to see it yet—"

Li Yan couldn't stop laughing, he couldn't help but laugh when he was amused by Yang Jian's words just now, he couldn't imagine that there was no one in this world who was perfect, although this guy was very good at arithmetic, but calligraphy was really like a three-year-old Huangkou child.

"Hmm. Sir, please take a look—"

Huang Xinghe respectfully held the yellow papyrus with the title written on it.

"This—this—are you sure your friend gave you the question?"

Li Yan finished reading the question, but he couldn't laugh anymore.

And, obviously, this question is more than a little bit bigger than yesterday's question.

"Yes, sir."

Huang Xinghe looked at Li Yan with an incredible expression, and suddenly had an answer in his heart.

"Your friend is really a strange person."

Li Yan said with a smile.

However, he also has no solution to this problem.

"That's true, sir."

Huang Xinghe didn't wait for Li Yan's consent, and he didn't dare to put away the yellow straw paper.

"Can you please ask this friend of yours if he has any intention of coming out to serve His Majesty the Emperor?"

As an advisor to His Majesty the Emperor of the Tang Dynasty, Li Yan is also responsible for discovering talents for His Majesty the Emperor.

"This, this, I'm going to ask that friend."

Huang Xinghe tiptoed Nie Ruoruo.

"Okay, I'm waiting for your news."

Li Yan looked at Huang Xinghe, but felt that the disciple who had always been well-organized was a little abnormal today, as if he was extremely reluctant to let his friend go out of the mountain?

Hey, it's not surprising that there are such strange people in the world, right?

"Yes, sir."

Huang Xinghe's heart tightened again.

His Majesty the Emperor urgently needs to be entrusted with a heavy task?

If His Majesty the Emperor knows that the person recommended by Mr. is still a yellow-mouthed child, what should he think?

"You go back first, put this question here first, and think about it when the teacher turns around, and give you news soon."

Li Yan actually didn't have any bottom in his heart, but his competitive spirit was stirred, just like the previous question, he really didn't believe that he would be compared to his disciple's friend!

"Okay, the disciple will retire first!"

Huang Xinghe bowed deeply to Li Yan, and then withdrew from the arithmetic hall.

Watching Huang Xinghe's figure disappear from the arithmetic hall, Li Yan's tense nerves finally unloaded.

"Doctor, I'm tired today, why don't you take a break early?"

Today's doctor has been going to that cloth shop for cloth very early.

However, what he didn't know was that Li Yan went to Buzhuang again today to think about whether he would have another adventure and meet the child who was extremely fast in mental arithmetic last time.

However, no matter how Li Yan inquired, the guys and bosses of Buzhuang didn't know anything about the old man and child who appeared last night.

Li Yan was also very discouraged.

Has there been any change in the sky this year?

As the first person in arithmetic in the Tang Empire, Li Yan felt that there were a lot of strange things this year, the child with the fast algorithm, and Huang Xinghe, a strange but mysterious friend, all fascinated and confused.

"I'm not tired, Liang Quan, you can find out that fur fur for your teacher."

Li Yan thought about it and already had a plan in his heart.

"Sir, going out?"

Liang Quan looked at Li Yan and wondered in his heart, the sky was already dark now, where did the doctor plan to go?

"Yes, if you go out for the teacher, you will go with the teacher, and the school will lock the door for the time being."

Li Yan instructed Liang Quan.

"Yes, sir."

After Liang Quan finished speaking, he went to find his fur for Li Yan.

Outside the house, I don't know when the snow fell again.

A plum tree in the corner of the school hall bloomed with many fresh flowers.

The snow is falling, and the fragrance of plum is overflowing.

This is the most beautiful night in Chang'an City.

In a place in Chang'an City, someone stood in front of the window, he was dressed in a bright yellow robe, a room like an open, a lamp like a bean, indescribably lonely and bleak.

He knew there was going to be a distinguished guest tonight.

He had been watching the heavy snowfall, and the people behind him were already lighting a fire in the charcoal stove, and the water in the kettle had gradually begun to jump and sing.

The water is boiling.

He had already prepared the best snow mountain silver needle tea, waiting for the person who was approaching in the wind and snow.
