Chapter 263 The Gap Is Too Far
Before stepping on the steps of the gate of the tribute courtyard, Li Xiaonan heard the hustle and bustle of laughter in the tribute courtyard.

Gu Yan snorted vaguely.

His uncle advocates Zhang Youchi's unrestrained nature, but every time he releases it and can't take it back!
Li Xiaonan quickened her pace, just as she passed Gu Yan, Wan Qing hurriedly took a step forward, grabbed Li Xiaonan, and let go of her hand quickly,
Li Xiaonan staggered when she was pulled.

Gu Yan and Mrs. Wei Si looked at Li Xiaonan together.

Li Xiaonan stabilized her body, smiled hurriedly, and signaled Gu Yan to leave first.

Gu Yan cast a sideways glance at Wan Qing, then lifted her foot forward.

Fourth Lady Wei tried her best to hold back her laughter, and raised her hand to pat Wan Qing who lowered her eyebrows and lowered her eyes.

When Gu Yan raised his foot and stepped over the threshold, there was a clear and loud sound of whips, and the hustle and bustle in the palace suddenly stopped, replaced by the sound of chaotic footsteps.

Li Xiaonan hurriedly took a step forward, held her breath, and slightly stretched her head to look into the courtyard.

Wei Xuezheng and others who were waiting inside the door hurried forward and stood in a row with their hands down.

Wei Xuezheng looked at Li Xiaonan, who was standing next to Gu Yan, stretched his head and looked around, and then looked at his nephew, feeling depressed and sad. He, a nephew who is literary and martial, handsome and powerful, wants to marry Such a vulgar country girl!
Ugh!
Li Xiaonan followed closely beside Gu Yan, turning her head to look around as she walked.

Scholars attending the class stood in square formations on both sides of the road, and in front of each square stood a board that was exactly the same as the one she had prepared, and two clerks stood beside the whiteboard.

Li Xiaonan thought about Shi Gun's introduction, um, it's just an artificial live broadcast classroom, I don't know how effective it will be.

Gu Yan glanced at Li Xiaonan from time to time, put his hands behind his back, with an uncharacteristically cold face.

Alas, looking left and right looked completely lacking in dignity. He was afraid that if he kept his kind gesture like before, Ah Nan would not be able to suppress the situation in lectures and would become chaotic.These young scholars are the most courageous and don't know the severity.

Li Xiaonan looked at the well-behaved scholars standing one by one, and only dared to roll their eyes, and wanted to sigh, the rules here are too strict!
The lecture place seems to be a place specially used for lectures, a square pavilion, sitting on a stone base about two feet high.All the door panels on the four sides of the pavilion have been removed, there are steps on all sides, and there is a white board under each step.

Gu Yan stood under the steps, beckoning Li Xiaonan to go up.

Li Xiaonan lifted her skirt and walked up the steps briskly.Wan Qing bowed her knees at Gu Yan, and followed Li Xiaonan up the steps.

She is Li Xiaonan's chief assistant.

Gu Yan watched Li Xiaonan sit down in the middle of the pavilion, then turned around and entered the tent that was temporarily set up on the side.

Wei Xuezheng followed behind Gu Yan, muttering, "I'm really ignorant and fearless."

Gu Yan looked back at Wei Xuezheng, "Don't worry."

In the pavilion on the stage, Li Xiaonan went straight to the point, "Now let's talk about the first question of island arithmetic."

Li Xiaonan paused, Wan Qing hurriedly took out a scroll marked with a word from the box that had been placed in the middle of the pavilion, and each of the four servants handed one to the four steps, Wan Qing lifted the one that was in the middle of the pavilion. Red silk on a white board.

After Li Xiaonan finished speaking, she pricked her ears to listen to the surrounding waves, as if it was okay.

Mr. Shao and Ni Rushi stood in the phalanx of scholars, listening to the voice, they stretched their heads to look at the whiteboard.

The clerk next to the whiteboard had seen the icons beforehand, took a glance at them, and quickly drew them with a charcoal pencil and long ruler.

The picture is very simple, a triangle with a diagonal line and two straight lines in the middle.

Ni Rushi frowned and looked carefully. Mr. Shao nodded and smiled. It was a good start, but the calculation of the island is too simple.

"How to solve this problem, everyone sitting here must already know it, so I will skip it. This problem uses similar triangles. Let's talk about the judgment of similar triangles. How to judge whether two triangles are similar Triangle, how to prove..."

Ni Rushi was stunned, and looked at Mr. Shao subconsciously. Mr. Shao stretched his neck and stared at the triangles drawn one by one on the whiteboard, obviously unable to keep up.

Ever since Li Xiaonan skipped a word, Wei Xuezheng became confused, but he has never been good at Gezhi, so Wei Xuezheng turned his head and asked the professor Gezhi of the government school, "Which book did she say this from?"

Professor Ge Zhi frowned and shook his head.

"Then do you understand?" Wei Xuezheng looked at Professor Gezhi.

"It's okay, don't talk." Professor Gezhi frowned.

"Speak slowly with Miss Li." Gu Yan calmly ordered Shi Gun.

He has experienced how profound Ah Nan is in style.

In the pavilion, Li Xiaonan paused, "About parallel lines, do you have any questions?"

There was a moment of silence in the crowd, and someone raised his hand, "Students think that visual inspection is enough."

Wan Qing immediately looked at Li Xiaonan, smiled like a flower and threw herself at the two paper tubes.

Sheets of thin and transparent bamboo shadow paper were spread from all sides, and straight lines were drawn on the bamboo shadow paper.

Immediately afterwards, another piece of tissue paper covered with dark and light color blocks was passed out again, and the clerk followed the instructions and placed the color block tissue paper under the bamboo shadow paper.

After a moment of silence, screams sounded, and the scene became chaotic.

"Now, can you still judge by eye? Seeing is not necessarily believing." Li Xiaonan said with a smile.

Wan Qing squeezed her smile hard, tiptoed slightly, and watched the chaos below the stage.

Wei Xuezheng stared at the parallel straight lines that twisted instantly after the tissue paper was placed on the pad. The lines became chaotic again, and grabbed Professor Gezhi, "What's going on? How could it be like this?"

"I don't know either!" Professor Ge Zhi stepped forward, lifted the bamboo shadow paper, looked at it, put it down, looked again, and lifted it up again.

"Why do our eyes see wrongly when we put those colors on the mat? Why are we in the mirror opposite to our left and right? If we can really understand the calculation of the island, we can understand why."

Ni Rushi stared at the lines that were sometimes straight and sometimes chaotic, and listening to Li Xiaonan's words, he was full of bewilderment. He looked at Mr. Shao who was frowning, knowing that he definitely didn't understand, so he couldn't help asking, "Mr. How is this going?"

"I heard that there are handouts." Mr. Shao answered an irrelevant question.

Gu Yan stood at the door of the tent, looking at the chaotic and dazed scholars with a half-smile.

He knew they couldn't understand!
In the tent, Wei Xuezheng grabbed Professor Gezhi again, "Do you understand?"

"Enlightened and enlightened. Don't talk!" Professor Gezhi slapped Wei Xuezheng away.

Wei Xuezheng glanced sideways at the sweaty Professor Gezhi, and walked up to Gu Yan, "I didn't expect the sea island almanac to be so profound, I see..."

"Whether the Sea Island Calculus is advanced or not depends on whether you meet someone who is advanced. When you told me back then, it was not so advanced." Gu Yan said bluntly.

"That's that, uncle is not good at style." Wei Xuezheng smiled dryly, "I mean, I want everyone to read the handouts. Miss Li's lectures are too bright. You see, even Lao Liu I don't understand."

Gu Yan tilted Wei Xuezheng, and hummed for a moment.

This is what he wanted, and he couldn't bear to let Ah Nan talk about it for a day!
Li Xiaonan's lecture lasted only half an hour, so she and Wan Qing moved to the lobby at the back, leaned on the window sill and looked at the classrooms on both sides and groups of scholars in the middle of the yard led by professors or seniors, facing the whiteboard Concentrate your eyebrows and save your forehead.

"Is it that difficult?" Li Xiaonan looked at Miss Wei and asked.

"Father has already urgently handed over a handout to the Imperial Academy. There is a Gezhi hall in the Imperial Academy." Mrs. Wei Si bowed slightly, very respectful.

Their Wei family respects true scholars most.

Li Xiaonan rested her chin and sighed with a heavy heart. If what she wrote today was too rare, then the things she planned to write would be useless if no one could understand them.

She's trying to find a way to write a basic book first!
