The small garden of the Li Mansion.

A pond with many koi fish and lotus flowers is sparkling in the deep weeping willow branches and the warm sun. Although it is late autumn and the pond is full of dead branches and leaves, it is also a bit wild and elegant.

At the edge of the pond, there is a small flat open space, and a small pavilion built against the pond.

This is the favorite place of the old lady in the Li Mansion, in the morning, you can stretch your fists and feet in the open space, and practice the five bird plays. In your spare time, you can enjoy tea and fish leisurely in the small pavilion.

At this time, in the small pavilion, Li Mao, Li Yu, Lu Zi and the three of them were sitting quietly, looking at the open space outside the pavilion and leisurely tasting tea, and talking and laughing softly from time to time. Only Lu Yunpeng was busy with the three elders on the side, making tea and handing pots, and he was so busy that he was sweating profusely.

In the open space outside the pavilion, a unique "examination" is also in full swing - but the situation in the examination room seems to be a little too one-sided......

I saw Xie Xiuqi standing leisurely in the clearing, looking left and right idle. A scholar opposite him was sweating on his forehead.

The scholar thought about it again and again, and finally opened his voice again with hesitation: "Gongzi Xie is invited, I still want to ask below, can Gongzi Xie know the principle of Kong Ming Lantern flying in the sky?" If so, please elaborate. ”

After speaking, he looked at Xie Xiuqi desperately.

Xie Xiuqi rolled his eyes, he was already feeling a little bored: "The air is heated and expanded, and the density of the air in the lamp is less than that of the outside air, which produces buoyancy, so it can fly into the sky." ”

"Alas......"

"How did he know?"

"And it's a few words."

"How so?"

The group of scholars sighed again, and many of them were full of incredulity.

Lu Zihe took a leisurely sip of tea, and he looked at the young people in the audience lovingly, his eyes were already full of pride and pride.

Li Mao also looked at the field with a smile, whispering to Li Yu from time to time, causing Li Yu to nod his head for a while, looking at Xie Xiuqi's eyes with shock, but the suspicion gradually faded.

Li Xi looked at Xie Xiuqi while eating, only to see her thin eyebrows frowning tightly, and her dark eyes were full of surprise.

Last night, the girl was reprimanded by her father, ran out angrily, and went straight to the county school.

The strong attack didn't work, so he used his brains to be indomitable and came up with a roundabout strategy.

A great truth, with the momentum of all the students, with the fairness of the teacher, to block the mouths of the father and grandfather - it is similar to Xie Xiuqi who instigated the school to make a big disturbance in the superintendent.

Strike while the iron is hot, and use a cynical and agitated method to force that bastard into a corner - if he dares to take the exam, he will bring humiliation on himself, if he doesn't dare to agree, how can he have the face to apprentice?

The script was perfect and everything went smoothly. However, it was at the time of this final blow...... After a few teas, the bastard was leisurely, but the people on his side retreated one by one?

What went wrong...... How so?

The girl thought with a frowning little brow, and her heart was full of puzzles.

was hesitating, but saw that the scholar who had just asked the question was already full of anxiety and retreated gloomily.

In an instant, another of his own generals was lightly beheaded by this bastard, and the girl's heart was gradually becoming a little anxious.

"I'll ask him!"

I saw that she waved her hand violently to stop a scholar who was about to ask a question, and his face was gradually a little unbearable, but she stood up angrily.

Xie Xiuqi glanced at the girl with a smile.

The younger brothers were killed and wounded, and finally couldn't bear it anymore, so did they want to go into battle by themselves? I'd like to see the beautiful girl of science who was able to invent picric acid a hundred years before the West...... What to ask.

He thought with a smile.

Li Xi no longer dared to underestimate the person in front of him at this time.

No matter how much he despises his morality, but the facts are the facts, and the grandpa praised it last night is probably not groundless......

The girl's heart was already very vigilant, but after she stared at her eyebrows and thought about it, she didn't know what she thought, and her eyes suddenly lit up.

I saw her look at Xie Xiuqi proudly and asked crisply, "If there is an iron ball, the radius is 1 centimeter." To pour copper on it, the thickness of the copper layer should be 0.01 cm, and the required copper volume should be geometric? ”

"How does this ......" "I've never seen such an arithmetic ......"

As soon as Li Xi's words fell, there was a murmur of doubts in the group of scholars.

Li Mao in the pavilion shook his head with a smile, and his eyes were full of helplessness when he looked at his little granddaughter.

This girl is just playing tricks in a fit of anger...... How could Xie Xiuqi calculate this question?

Meet...... The old man will be happy to end up for this Xie Xiuqiyuan, Xi'er is a little nonsense.

The old man thought to himself.

This is...... Differentiation in calculus? Xie Xiuqi also shrugged his eyebrows in surprise.

Ancient mathematics seems to be the part of mathematics, physics and chemistry that King Yongzu has changed the least. After all, since ancient times, the six arts of Confucianism have one of the "number" arts, but there is no need for King Yongzu, who is not to make up for the shortcomings of ancient science, to elevate his status again, and spend energy on it.

But calculus ...... It seems that the West was the first to propose it in the eighteenth century...... Looks like Newton?

But I don't want to...... Sure enough, in this new ancient period, the pace of evolution of our Great Chinese civilization has also accelerated slightly with the introduction of science?

The young man was thinking about it, Li Xi looked at the silent young man, but he gradually became very proud.

Any idea who made this question?

Chen Xiao, whose name is Jingrun, is currently an academician of the Imperial Royal Academy of Sciences, a president of the Mathematics Branch, and a close friend of his grandfather!

This is the result of Grandpa Chen in recent years, and "Differential Guessing and Algorithms" is currently only being demonstrated and disseminated among the high-level of the imperial scientific academic community, and has not been circulated outside.

I only found out when Grandpa Chen wrote to discuss with my grandfather, and he couldn't have known-Hmph, you forced this girl, and if you have the ability, you can answer it again, so I can't believe it and I can't ask you!

The girl thought triumphantly.

As she smiled, her gaze suddenly froze—she saw that the young man had picked a branch, but he was writing and scratching on the ground.

What is he doing here? Rushing to the doctor? Do the math? The girl thought in disbelief.

Li Mao's eyes were also slightly fixed, he looked at Xie Xiuqi's actions of writing and drawing on the ground, but he sat down again with the figure that stood up and was ready to play the round, and his eyebrows were full of surprise.

The scholars exclaimed in surprise one after another, and looked at the young people on the field desperately.

As far as everyone could see, it didn't take long for the young man to smile.

"About 0.13 cubic centimeters."

He nodded in satisfaction and chuckled.

Li Xi was stunned for a moment.

"How could it be ......," she muttered, Xiu's face full of incredulity.

"Did he get it right?" One of the scholars asked.

Even Li Mao's gray beard in the pavilion couldn't help trembling, showing that he was shocked in his heart.

Fortunately, when my brother was in college, he was so impressed that he was so impressed that he hadn't returned it to the teacher...... The young man laughed in his heart.

was complacent, but Xie Xiuqi suddenly glanced at the pavilion on the side, and Li Mao was also shocked.

Am I overdoing it again? Could this be the new research? Yes, even if I am smarter than Westerners, and even if I have a long history of ancient arithmetic, it is impossible for me to be far ahead of the mathematical theory invented by Westerners and the beach giant Newton at the end of the 17th century......

Fuck, I've got a daddy, you girl tested me as a waste, and you actually came up with a scientist's question? Is this like taking the Goldbach conjecture as a college entrance examination paper in the 21st century? It's crazy, isn't it......

Xie Xiuqi glanced at Li Xi, who was stunned, and he already hated it in his heart.

And how is that good? No, I should do something.

I saw him thinking like this again, and in a flash of thought, he had already taken a deep breath.

Oscar, give me strength!

He prayed silently in his heart.

Suddenly, Xie Xiuqi had already pretended to be stunned on his face.

"Am I not right?" He stumbled, but looked at the equation on the ground with a confused face.

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

He looked at the equation on the ground, and muttered puzzledly: "That time I flipped through my sister's notes, and I learned it when I saw this interesting...... The equation seems to be correct...... That's exactly how it counts...... Right? ”

He couldn't stop muttering in disbelief, and even looked at Li Mao on the side, his eyes were already full of timidity for help.

A hint of relief suddenly flashed in Li Mao's eyes.

This has also been mentioned to Wei'er, so it's no wonder...... It's just that he must have been a prodigal at that time, right? Just look at it and learn it? Xi'er Wei'er had studied with this sad face for a few days, and she still didn't understand it......

Mathematics, the foundation of science. I forgot about it that day, but I talked to him a lot. But I don't want his talent in science to be so comprehensive, and his talent is so high without a great change. It's just that I've been wandering for many years, and I haven't revealed it...... No wonder Lord Lu once said that when he was a child, he was actually smarter than Wei'er.

Thinking like this, the old man looked at Xie Xiuqi with more and more satisfaction.

Xie Xiuqi glanced at Li Maoyou's contemplative expression after the play, but he thought that his remedy was not successful enough, and he panicked in his heart.

No, I should have done something!

The young man thought about it anxiously, only to see him cough dryly, and he already looked at Li Xi, who was still flustering on the side, and said proudly: "What are you doing, I don't know if the answer I have solved is right or not?" ”

Li Xi was stunned and was about to speak, but saw that the young man sneered again: "Come and don't be rude, since you have already finished taking the test for me, I will also test you, I don't know if you dare to respond to it?" ”

Li Xi bit her lower lip, and a trace of annoyance appeared on the girl's face.

"You say." She puffed out.
