In the palace, Emperor Yu sat at his desk reading a book, and beside him was the gentle and beautiful Dou Guifei.

Dou Guifei, the younger sister of Dou Jianming, the protector of the country, was deeply loved by Emperor Yu after entering the palace.

In the study, there are two more people, the crown prince and the king of Ji.

On the paper in front of Emperor Yu was the wheat grain chessboard problem, and after complicated calculations, an astronomical number was finally reached.

But even if you solve this answer, you will lose face more than 100 years ago, because the most complicated method is used to solve this problem, and you add it step by step.

What the emperor wants to know most now is that in this township test, Jiang Han finally used his skills to solve this question, or there was fraud.

Because when taking this subject, Jiang Han only took less than half an hour to hand in the paper in advance.

And these days, the emperor is also trying other ways to solve the problem.

However, to no avail.

At this moment, the eunuch outside the door said, "Your Majesty, the eldest princess is here." ”

The emperor raised his head: "Let Ning Yue come in!" ”

Princess Ning Yue quickly walked into the imperial study, her eyes calmly swept over the faces of the crown prince, King Ji, Dou Guifei and others, and said, "I went to see Jiang Han today. ”

The emperor said, "How is this person?" ”

The crown prince and King Ji also looked at the eldest princess, only the noble lady Dou lowered her head and polished the ink, but a trace of curiosity flashed on her face.

This Jiang Han is the son-in-law of Ning Guofu, right?

Why does the emperor pay attention to a son-in-law?

Ning Yue groaned: "This son, his talent is amazing!" The way of arithmetic is even more unfathomable! More than 100 arithmetic problems were indeed solved by himself! ”

Everyone in the study was a little surprised.

Princess Ning Yue is talented, she is the most talented among the princesses, and it is rare for her to praise a person like this.

Next, Ning Yue began to tell about seeing Jiang Han today.

Of course, she omitted to eat the barbecue because it was irrelevant.

Hearing Jiang Han's question of chickens and rabbits in the same cage, the prince and King Ji all looked at each other, and their faces changed slightly.

This question is too tricky and weird!

If you want to solve it, you can solve it.

But it needs to be calculated step by step, and the wrong answers need to be eliminated step by step.

Then, hearing Jiang Han's solution, the crown prince and King Ji were shocked again.

There are three solutions to this problem?

The first solution is a little complicated, but the emperor thought about it carefully, and found its ingenuity, and he couldn't help but marvel in his heart, what a clever way to solve the problem!

The second solution is simpler and faster, and the emperor is even more shocked in his heart, how did Jiang Han come up with this solution?

But here's the big thing!

When Ning Yue talked about setting unknowns and setting equations, everyone, including the emperor, was stunned.

Actually, there is such a solution?

How can it be so ingenious?

How the hell did this man come up with it?

That's too smart, isn't it?

Ning Yue looked at the reactions of the crown prince, King Ji and the others, and felt a little more comfortable, and when she heard this solution, she was just as surprised as them.

Finally, Ning Yue talked about the proportional sequence.

It's just that Jiang Han didn't know much about the number of equals, and Ning Yue only understood part of it, and after saying it, even the emperor frowned when he heard it.

Do not understand.

But I finally knew what kind of method Jiang Han used to solve the problem.

As long as you substitute that formula, you can easily solve it.

This son is really a genius!

It's no wonder that Zhongli Wuwu is so impressed!

Lady Dou said: "Your Majesty, since you know the solution, you can teach a little eunuch first." Tomorrow morning, summon more than 100 envoys, let the little eunuch solve it in person, and tell him, I can solve this problem, even a eunuch can easily solve it, the reason why I waited until this time is just to give you more than 100 face. ”

The Emperor said, "Okay, so be it." ”

……

Princess Ning Yue left the imperial study and returned to the princess's mansion. When I looked up, I saw a woman in white sitting in my room.

The woman held a book in one hand, pastries in the other, and a jug of wine on the table.

I saw that she first stuffed a piece of pastry into her mouth, chewed it twice, then grabbed the wine jug, tilted her neck, and drank the wine with a grunt, without any image at all.

Princess Ning Yue seemed to be accustomed to it, her expression was indifferent, she came to sit down beside the girl, and said, "Aren't you guarding Nannuma Town?" What are you doing in Kyoto? ”

The girl changed her posture, put the book under her, and read the book while eating pastries: "There is no war in Nannuma, I miss you, so I came." ”

Princess Ning Yue raised her eyebrows slightly and said, "Over there, are you ready to send troops?" ”

The girl's hand holding the pastry stopped, and then stuffed it into her mouth, and said, "You're still so smart, it's really boring." ”

Princess Ning Yue said: "Yi country to Si You fourteen states as the color head, the imperial court naturally has to make two preparations, if the Mid-Autumn Festival Wenhui can not succeed in winning the leader, then send troops to conquer Yi, Nanmarsh is the closest to Yi country, if there is a war, you must mobilize your White Tiger Army." But...... You didn't just come to Beijing for this, right? ”

The girl said: "Well, I have an old relationship with Ning Guofu, and I am going to visit Beijing this time." ”

Princess Ning Yue sneered, "What old do you have? It's just ......"

The girl's eyes froze, and she looked at her.

Princess Ning Yue immediately did not speak.

The girl sighed lightly: "After coming to Kyoto, I found that Ning Guofu had fallen like this. I heard that the eldest lady of Ning Guofu recruited a son-in-law, a scholar with weak letters. Unexpectedly, the Qin family casually recruited a weak scholar as a son-in-law. ”

The girl said: "I heard that this person is a poor scholar in Yunmeng City, with no fame, no literary position, and no martial arts. It's also a little stupid - after all, you can't even pass the child exam, isn't it stupid? ”

Ning Yue looked at her a little strangely: "You didn't inquire about this person?" ”

"No, not interested." The girl took another horseshoe cake and stuffed it in her mouth, and stuffed it with a bulging mouth.

Ning Yue said: "The female general of Nannuma is naturally not interested in a son-in-law...... However, is your book good? ”

As she spoke, Princess Ning Yue glanced at the book that the girl was reading, which was a copy of "The Biography of Wu Song".

"It's good-looking, but I don't know who the author is...... Ning Yue, help me find out the author of this book, I want to tie him back to Nanmarsh and write a book day and night. ”

"Okay, I'll check." Princess Ning Yue chuckled.

"Of course, there's no need to rush, I still have to go to Yiguo and do something." The girl grinned, revealing two rows of neat white teeth.

Princess Ning Yue looked at the girl, the general of the South Marsh White Tiger Army is going to Yiguo? Don't stir up the country?

"Anyway, where have you been today?" The girl asked.

"I went to meet a talented man who solved an arithmetic problem for Da Yu."

"What kind of talent?"

The eldest princess muttered: "Eight buckets of talent, five cars of learning!" ”

The female general said: "Even you say so, which makes me a little curious." ”
