"Good understanding!"

Lu Li nodded in appreciation, "It's heavy rain, you have a platinum shape. Work hard! I look forward to your book to the top and attaining the gods."

“Must!”

Fatty Yuwen laughed loudly and was full of fighting spirit.

"Why are you laughing at? I'm in my senior year of high school, but I still don't know how to study hard?"

Old Xu roared, blowing away Fatty Yuwen's spirit and fighting spirit with all the rain and wind.

As his neck shrank, Fatty Yuwen hurriedly buried his head in reading.

Lu Li still remembers the "stimulation" of Lao Xu. He didn't dare to explode the thorns and honestly picked up the homework book.

But... Lu Li picked up a pencil in his hand and sketched it on his homework book.

When drawing sketches, Lu Li once again lamented the powerful auxiliary role of "not forgetting after seeing".

After seeing it at first glance, I remembered the picture in my mind.

When Lu Li draws, he just needs to describe the pictures in his mind.

Sketching requires a certain ability to imagine space and position the ability to position the space. In essence, whether it is spatial imagination or positioning, it is all mathematical problems.

Mathematics is Lu Li’s strength.

After thinking for a moment, Lu Li immediately constructed a spatial coordinate system in his mind, and then determined the coordinate positioning of the picture in the form of views and projections.

The pen is placed on paper, and the center line is used as the reference to accurately locate the entire composition, accurately calculate the proportional dimensions, and perfect light projection angle.

The tip of the pen is zipping on the homework book. The calm mentality makes Lu Li very calm, and his skillfulness makes Lu Li's strokes very accurate.

At the beginning, a coordinate system appears on the paper, followed by coordinate points one by one, followed by projection lines one by one.

At this moment, there was a completely geometric figure on the paper, and no one thought it was painting.

Even Lao Xu, who was passing by, nodded slightly when he saw the coordinate axis and projection line drawn by Lu Li on his homework book.

A three-dimensional coordinate system has accurate proportions and rigorous composition, which means that the coordinate points appear irregular. What curve is being calculated?

Old Xu glanced at Lu Li, and a hint of praise flashed in his eyes. Not bad! From this coordinate system, you can see that Lu Li's math foundation is not bad and has made great progress.

A smile appeared on the corner of his mouth, and Lao Xu nodded slightly. He is already in his third year of high school. With this progress, as long as he keeps going, it is no problem to take the undergraduate degree.

With his hands on his back, Old Xu patrolled the classroom.

After a round and seeing the students in the class studying hard, Lao Xu was also very pleased. After all, it was a key class, the learning atmosphere was relatively strong and the learning style was relatively good.

Turning around and getting ready to go out. When he walked to the door, Old Xu saw Lu Li still drawing on the paper.

Well? A coordinate composition can be used to get a curve by taking a few key coordinate points. Why haven’t it been calculated for so long?

As a teacher and a math teacher, teaching and solving doubts is your job.

Old Xu stopped, turned around and walked towards Lu Li.

Walking to Lu Li, looking down... I'll go!

Old Xu's eyes are about to bulge out!

Where is this coordinate composition and where is the curve calculation?

On Lu Li's homework book, he suddenly drew the look of Lao Xu standing at the door of the classroom and staring at the classmates in the classroom.

The precise dimensions, perfect spatial coordinates, and appropriate light projection portray Lao Xu's image vividly, and even his eyes reveal a sense of eyeballing.

What shocked Lao Xu even more was that in this picture, even the wrinkles on his face were depicted very accurately, giving Lao Xu the feeling of looking in a mirror.

The reason why Lu Li was still drawing constantly is because... he was taking points for each wrinkle, calculating coordinate points, and outlining the wrinkle curve.

At this moment, Lao Xu didn't know what expression he had on his face, and he didn't know what it felt in his heart.

You even calculate each coordinate point. If you have this ability, just to draw a painting? And... you also paint me so ugly?

“Good drawing!”

Old Xu knocked on the table and stared at Lu Li with a blank expression.

"ah?"

Lu Li was immersed in painting and came to his senses when he heard this.

Looking up, Lu Li looked at the paintings drawn on the paper again, and a hint of embarrassment flashed across his face.

"Bring your paintings and follow me!"

Old Xu waved his hand and turned around and walked out of the classroom.

"Lao Lu, you... can still draw?"

Fatty Yuwen saw Lao Xu drawn on Lu Li’s homework book and trembled all over, “You...why are you not good at drawing? Why do you want to draw Lao Xu? Are you drawing evil-proof?”

“A commemoration.”

Lu Li picked up his homework book, got up and walked out of the classroom, and once again came to Lao Xu's office.

Lao Xu sat at the desk, holding a cigarette at his fingertips, slowly took a sip, looked up at Lu Li, "Show me the painting."

"OK!"

Lu Li quickly handed over the homework book.

Lao Xu reached out to take the homework book and opened it to see the painting. His eyes fell on the formulas on the page next to him, and Lao Xu's eyes became a little helpless.

"You calculate so many coordinates and so many curves to draw a picture?"

Lao Xu doesn't know what to say.

You said Lu Li was not doing his job properly? When he was drawing pictures, he clearly did countless math problems and solved countless coordinate points and countless curves.

You said he is doing his job properly? He does so much just to draw a painting.

“Sketching is about truth.”

Lu Li smiled, "Mathematics is the most realistic language in the world. Any sketch is essentially composed of points and lines. Points and lines are all mathematical problems."

"Use mathematics to draw..."

Lao Xu touched his head with a deep hairline, and his face looked very strange. "It can be seen from this painting that your math level has improved a lot. As long as you keep it, it should be fine to take a key undergraduate degree during the college entrance examination. What are you... studying painting for?"

"Art students can also take the key undergraduate exam."

Lu Li was also a little helpless. I am here to be a "craftsman" and a top student... it is not my mission route.

"You want to take the path of artistic life?"

Old Xu almost choked by a puff of smoke.

He reached out and put the cigarette butt out in the ashtray. Lao Xu looked up at Lu Li, "Art specialty? This road is not easy to walk! And... With your grades, isn't it good to work hard to get a major exam? Why do you have to narrow the road?"

There is a common concept in high school campuses. That is, the right way to take the college entrance examination is to take the right path. Students with sports talents, music talents, and art talents are all "side doors".

I have no choice! Who says the task requirement is a "craftsman"?

Lu Li sighed in his heart. The admission to the "Central Academy of Fine Arts" through his art expertise is only the first step to getting started with a "craftsman". There are still many things to do in the future.

"Teacher, I'm interested in this."

Lu Li could only explain this, "Because I was interested, I improved my math level in order to draw. This... should be a good thing, right?"

Interest is the best teacher, and it is of course a good thing to be interested.

Lao Xu sighed secretly, "You are still young, and you should discuss more with your parents about your life path. No matter what, the teacher is very happy that you can improve your math level now."

"Thank you, teacher."

Lu Li also knew that Lao Xu was talking to him because he was concerned about the students and was responsible for them.

"Okay!"

Old Xu nodded to Lu Li, "You go back and discuss with your parents. If you have to take the art route, you cannot ignore cultural courses. After all, culture is the foundation."

"Okay! Thank you teacher."

Lu Li thanked Lao Xu, stood up and said goodbye, "Teacher, I'll go back first."

"Yeah! Go down!"

Old Xu waved his hand to Lu Li.

Lu Li turned around and walked out of Lao Xu's office and returned to the classroom.

"Old Lu, I just thought about it, and suddenly I feel... you are very brave."

When Lu Li had just returned to his seat, his deskmate Yuwen, who was next to him, came up terrifiedly.

"Brave? Why do you say this?"

Lu Li was stunned, not knowing what Fatty Yuwen was talking about.

"You painted Lao Xu's portrait! Your painting looks like a portrait!"

Fatty Yuwen shook at Lu Li and looked at him.
