The next day.

He was wearing a school uniform, a high-yield backpack, his left hand inserted into his trouser pocket, and his face was full of wooden and emotional indifference.

"No. 3 Middle School...I'm coming."

Bang.

Gao Yi slammed the door and walked out.

Click.

Gao Yi opened the door and came back.

"I'm super, I'll freeze you to death!"

The temperature dropped suddenly today, and it finally started to look like winter. The wind was like a bone scraper. Gao Yi didn't have any magic resistance on his body, and his defense was broken immediately when he went out.

Reluctant to change the painting. After thinking about it for a while in the room, Gao Yi finally made a decision.

Put on another autumn school uniform outside.

No. 3 Middle School is not very far from my cousin’s apartment, and can be reached directly by bus at one stop.

Gao Yi got off the bus, and not far away was the gate of No. 3 Middle School. Students in twos and threes, arm in arm, were entering the campus one by one under the inspection of the teacher on duty.

"High justice."

A middle-aged teacher waved to him.

"Teacher Ma?"

Gao Yi was trying to escape.

Teacher Ma suddenly came over, grabbed his arm, and frowned: "Why are you wearing so little? Isn't it cold?"

Gao Yi said it was okay.

Because the clothing customized through different paintings has various attribute bonuses.

Now, even if he is just a member of the support system called [Learning Activist], he can defeat normal adults just by relying on his body alone.

If it were [Mystery and Surprise], it would be even higher.

"Teacher Ma, it's not good to talk too much in front of everyone..."

Gao Yi reached out and wanted to pry Teacher Ma's fingers.

Next is you——

Teacher Ma!

"It's good if it's not cold."

Teacher Ma calmly grabbed Gao Yi's rebellious hands, easily relieved the force with a move of four or two, and pushed Gao Yi into the small dark room.

"Elbow, come into the house with me. Your thinking needs to be corrected. You can't wait a moment longer."

???

Gao Yi stared, confused.

…

My name is Director Zhang, a sophomore in high school.

I like to do derivative problems very much, and I even prefer to use VR devices. I can swim freely in the ocean of mathematical mysteries and cannot extricate myself.

But due to school regulations, I cannot use VR openly.

But I won't compromise.

I really like to use VR to read questions in the empty laboratory building toilet with the door open and openly.

Just like Prometheus stole the light of fire, I also have the wonderful taste of stealing the fruit of truth.

Mathematics is really wonderful.

"Very good. You probably haven't reached this point yet, so I'll ask you a question first."

Director Zhang opened the cubicle door and brought the VR equipment.

"I will attack in Gundam form!"

"The big head is dead in the forest pit——"

The teacher's earnest instructions came from the earphones.

“…Because when ⊿x→0, ⊿x/x tends to 0 and x/⊿x tends to ∞, so lim⊿x→0loga(1⊿x/x)^(x/⊿x)=logae,

F……"

Director Zhang was so mesmerized that the teacher's explanation in VR slowed down a little after the climax.

Tick.

Clear sound comes from outside the headphones.

Tick.

Tick.

Sound of water?

Could it be that the toilet is leaking?

Director Zhang paused the headphones and listened carefully.

It shouldn’t be, wasn’t it already there just now?

Did someone come to the toilet?

But who would go to the toilet on the upper floor of the laboratory building so early in the morning?

Mud seems to be more excited!

continue.

Director Zhang continues to play.

"That's it. I didn't expect that this question could be solved like this. The teacher is really of a high standard!"

Another question ends.

Tick.

Tick.

Tick.

The sound of water was now clearer.

It's like... he has arrived at the door of the cubicle.

"Is anyone there?" he called softly.

"Classmate? Did I disturb you from going to the toilet?"

No one responded.

The temperature seems to have suddenly become colder.

Director Zhang suddenly felt a little creepy. He immediately raised his hand and wanted to pull off the VR glasses. Suddenly!

He felt something brush the tip of his nose.

The touch is like pieces of seaweed soaked in water that are stuck together, dry but a little moist.

An unpleasant stench, like a sewer that had been blocked for many years, entered his nasal cavity at the same time.

"Who is playing a prank!"

Director Zhang didn't care, grabbed the VR glasses and pulled them off violently.

nobody?

The toilet in front of me was empty, with no sign that anyone had just been there.

Director Zhang touched his chest and was about to take a breath, but his face turned pale.

He saw half a pair of water-stained shoe prints in front of his cubicle.

It was as if something had been standing in front of him, close to him with almost no gap.

Then, the footprints extended downward from the compartment, step by step, straight to the innermost compartment!

The innermost compartment door was tightly closed, as if someone had locked it from the inside.

"Haha, after all, some classmates are still joking with me."

Director Zhang's pale face softened slightly, but deep down he was a little unhappy with this classmate who was deliberately trying to mess with him.

I've come here to read the question, and you still want to punish me?

Okay, let's see who will prank whom later.
To be continued...
