I failed a course, and the system became my study supervisor.

Chapter 20 “Magnetic Rhythm and Flowing Light” Art Exhibition
By definition, magnetic fluid is a new functional material composed of magnetic particles, surfactants and base fluid, which combines magnetism, fluidity and stability.

However, what you see with your own eyes in reality is far more shocking than cold words.

The exhibition was set up in the exhibition hall of the school's function building. As soon as they entered the gate, Xu Ling and his companions saw a huge glass panel standing in the center with four large characters "Magnetic Rhythm and Flowing Light" written on it.

This should be the name of the exhibition, and if Xu Ling was not mistaken, the glass plate should be filled with magnetic fluid. These words were presented by magnetic fluid, and were definitely not an ordinary electronic screen.

There was no special tour guide, so Xu Ling and several roommates went around on their own.

The first thing that caught everyone's attention was a huge glass ball, which was mostly filled with inky fluid.

From a distance, it seemed nothing special, but when everyone got closer, Wang Rui exclaimed:

"I rely on!"

I saw the fluid in the glass ball surging rhythmically, and at the same time, a small circle emitting white light was rotating around the entire glass ball.

And that ring is not simple either. If you look closely, you can see that it is a circle surrounded by many sharp protrusions.

After walking past this big sphere, the next thing that comes into view is an ink-colored wall, which doesn't look special at all.

But as people walked past the wall, their outlines were reflected on it.

Huh? Coincidence?
Xu Ling then walked closer and kept changing his body posture. Then he was surprised to find that no matter what posture he was in, it could be recorded by the wall, and it was dynamic.

Several roommates were also shocked and quickly ran to the wall, posing in various coquettish poses.

"Yang Chaojie? What's this posture?" Xu Ling looked at Yang Chaojie who was performing Korean sexy dance with a frown on his face.

"You do not understand!"

Yang Chaojie ignored Xu Ling.

Seeing this, Wang Rui and Qin Kai immediately left the magnetic fluid wall, hid far away, and pretended not to know the strange man who was posing in a coquettish manner.

Seeing that the situation was indeed a bit awkward, Yang Chaojie stopped fiddling and quickly pulled his roommates to the next exhibit to appreciate it.

Title: Killing Time

This is a 2016 work by the sculptor Eric.

This is an introduction to the exhibits. Anything that requires an introduction must be extraordinary.

Indeed, this work is full of visual shock.

In the middle of the glass cabinet hangs a metal skull, and below the skull are two skeletons of hands in a lifting posture.

Then the inky magnetic fluid flowed down from the mouth of the skull, gathered into a ball in the skeleton's hands, and then flowed out from the gap.

The lost magnetic fluid will return to the top of the skull along a spine.

For a moment, Xu Ling and the others were so shocked that they were speechless. Words like shock and surprise were no longer enough to describe their emotions.

"I rely on!"

An exclamation came out of several people's mouths at the same time.

Don’t say that I am uneducated. I have traveled the world with my own words.

Before everyone's surprise had fully subsided, Qin Kai started yelling again:
"Holy crap! Look at that!"

Everyone immediately looked in the direction Qin Kai pointed.

Flowing Light

Author: Wang Xueqin

The visual flow of light is achieved through the action of magnetic fluid.

I saw a tetrahedron-shaped glass cabinet placed on the exhibition stand, and each side of the glass seemed to be covered with a thin film.

There is a static light source inside the glass cabinet, which continuously emits light of different colors.

However, to everyone's shock, the still light began to flow when it hit the glass.

Accompanied by soothing music, it has a unique flavor.

After staring at it for a long time, everyone suddenly remembered the introduction of the exhibits.

"Damn! Damn! Damn! Did you notice? The author is Wang Xueqin! She's our instructor!"

Wang Rui's words woke Xu Ling up from his dream. Surprised, Xu Ling recalled the scene of seeing Wang Xueqin in the library before. The book she was holding was "The Movement of Magnetic Fluids".

At this moment, a huge cry came from a distance:

"Wow--"

Xu Ling looked in the direction of the sound and saw a group of students gathered in a circle. They couldn't see anything.

"Let's go! Let's go over there and take a look." Xu Ling became very curious and called a few roommates to come to the crowd.

Only by standing on tiptoe could Xu Ling see what was inside.

In a large pool filled with magnetic fluid, the fluid around it continued to gather towards the center, then accumulated and moved on its own, actually forming a three-dimensional structure of the Eiffel Tower.

Before I could exclaim, I heard a familiar voice from the crowd:

"The Eiffel Tower is finished. Which students would like to see other buildings?"

Holy crap! It's customizable!

Xu Ling quickly shouted, "I want to see the Bird's Nest!"

"Okay! Then let it form a bird's nest."

Xu Ling finally recognized that it was Wang Xueqin's voice.

It’s just that I was blocked by the crowd and I don’t know if she could see me.

Never mind her! The most important thing is to look after the bird's nest.

Xu Ling stood on tiptoe again and stretched his neck.

In just thirty seconds, a complete bird's nest was formed.

The onlookers exclaimed again.

"Alright! I'm sorry, but the show has to end here. This device isn't suitable for long-term display."

Wang Xueqin said loudly.

"what--"

For a moment, the place was filled with grief and every student watching was filled with regret.

Only when the crowd finally dispersed did Xu Ling see Wang Xueqin next to the equipment.

A white shirt and black trousers made her look dignified and elegant. But she must be a little tired at this moment, with beads of sweat on her forehead.

"Eh? Xu Ling? You're here."

Wang Xueqin smiled.

"Yeah. Teacher Wang, you're amazing. I just saw your work."

Xu Ling also responded with a smile.

"Haha, I'm not too proud of my accomplishments, as long as you guys like me."

Wang Xueqin said this somewhat modestly.

She paused and continued, "I still have things to do. You guys can look around a bit more."

Xu Ling and others nodded repeatedly and watched Wang Xueqin leave.

Xu Ling's roommates were also very fond of Wang Xueqin.

Especially Yang Chaojie, his face was a little red and he couldn't speak clearly.

After all, who doesn’t like a gentle and beautiful counselor?

After seeing so many exhibits, Xu Ling was no longer shocked, but curious. How magical would an object with both magnetism and fluidity be? What are the laws of its movement?

Maybe this is what a top student is like, completely different from ordinary people.

Why do I say this? Of Xu Ling's three roommates, two kept saying "Oh my god!", and one was actually being infatuated with him.

As expected, it’s lonely at the top!
Xu Ling couldn't help but think.
