My skill tree increases every day.

It was 1:56 PM.

Lin Yu was standing in a long line waiting for the elevator at the foot of Teaching Building No. 5.

The school bell will ring in four minutes.

The teaching building has eleven floors in total, and the elevator is currently stopped on the 8th floor.

It is known that the elevator takes 5 seconds to ascend each floor and pauses for 15 seconds on each floor. Lin Yu's classroom is on the 7th floor. So, will Lin Yu be able to reach the classroom before the class bell rings?

Lin Yu was unaware of this, but he enjoyed the thrill of gambling.

It's definitely not because I'm too lazy to climb seven flights of stairs.

"Brother Yu, are we really going to keep waiting like this?"

Liu Zhiyuan asked somewhat guiltily.

"What else? Climb the stairs like those two losers?"

"But now it's already..."

Liu Zhiyuan had taken his phone out of his pocket three or four times in a minute, and seeing the time jump another digit, he finally couldn't resist anymore.

"Never mind, I'm going first!" Liu Zhiyuan chose to take the stairs.

ridiculous.

Lin Yu watched his disheveled figure running away and sneered inwardly.

Jingle Bell……

Lin Yu heard the school bell ringing in the elevator.

A group of people with calm expressions and normal demeanor stood in the elevator, and no one spoke.

Obviously, people who choose to take the elevator at this time will not have any emotional fluctuations because they are a minute or two late.

Soon, we arrived at the 7th floor.

As Lin Yu stepped out of the elevator, he turned around and saw Liu Zhiyuan running out of the stairwell, panting heavily.

"hello."

Lin Yu's expression remained unchanged.

Liu Zhiyuan was somewhat on the defensive.

There were no more seats in the classroom, only a few scattered empty seats.

Strangely, the podium was empty; the teacher hadn't arrived yet.

The teacher for this course is a new teacher who was just recruited last year. His surname is Wu, and he graduated with his doctorate a few years ago.

His characteristics are also very obvious.

One word,

roll.

Well, it's better if he's not here; it's like he wasn't late at all.

Although Ms. Wu is not as strict as someone who would fail you in class and cause your participation grade to plummet for the slightest mistake, she will still give you some minor punishments.

He was especially keen to try his hand at something fancy, like with students like Lin Yu, whom he had taught and knew.

Lin Yu glanced around and noticed an empty seat at the back of the classroom, near the door.

There are empty seats there?

University classes are relatively relaxed. Unless the teacher makes a special arrangement, students will usually subconsciously sit in the back.

What's wrong?

With a hint of doubt, Lin Yu decided to step forward and find out what was going on.

Soon, Lin Yu understood why.

"Ha. Ha. Good afternoon, teacher." Lin Yuqian chuckled twice and greeted him respectfully.

Professor Wu, who taught the course, was sitting calmly in the last row near the door, watching Lin Yu walk over with a half-smile.

"Lin Yu, we've known each other for a year now, and I really didn't expect you to have such guts." Teacher Wu smiled like a chrysanthemum. "I really didn't expect that you would dare to come in through the front door when you were clearly late."

"..."

No wonder there's no one here!

I said, even though it's not the best spot, there should still be people sitting there!

So someone's blocking the bridge here!

"Officer Wu, can this be considered turning myself in?"

"Okay."

Wu Wanhang graciously agreed to Lin Yu's suggestion.

"Please sit down. Remember to show everyone your notes next class."

Wu Wanhang stood up and patted Lin Yu on the shoulder.

Thankfully, it was just checking my notes. It wasn't a particularly serious punishment.

Wu Wanhang stood at the back door and glanced around the classroom. It was already full, so it seemed that everyone had arrived.

"Okay, then we..."

Wu Wanhang stepped onto the podium.

"Excuse me, could you please open the door?"

A low voice came from the back door.

Are there more experts?

Lin Yu turned around and saw a figure squatting outside the back door of the classroom.

The man crouched on the ground, carefully lowering his body and hiding in the blind spot under the observation window of the back door.

If Lin Yu weren't in his current position, almost touching the back door, and looking out from a perspective almost perpendicular to the door, it would indeed be difficult to notice that there was someone hiding there.

Does this work too?

If she had hidden there a minute earlier, wouldn't Wu Wanhang have caught her red-handed?

This is just too lucky!

Lin Yu quietly raised his hand and turned the lock on the back door that Wu Wanhang had locked from the inside.

The back door opened slightly, and Lin Yu peeked out and saw a delicate, pretty face squatting on the ground.

Su Wanqing looked up and met Lin Yu's gaze for a second.

Su Wanqing?

Half a semester has passed, and I didn't even know she was taking this class?

strangeness.

Su Wanqing was quite well-known at school. Although Wu Wanhang hadn't taken attendance this semester, someone like her shouldn't be completely silent in class, right?

"Excuse me, could you please check if the teacher has looked here?"

Lin Yu nodded and glanced at Wu Wanhang on the stage.

Just then, he turned his back and was explaining his PowerPoint presentation.

So Lin Yu reached behind him and gestured for him to hurry up.

"Not now, hurry up."

Su Wanqing's eyes lit up, she gave her a grateful look, and slipped in.

Su Wanqing was very flexible. Although she was squatting, it did not affect her agility. With lightning speed, she went around the back of the chair.

He sat down in the seat that Wu Wanhang had just been sitting in.

They were quite quick.

But Lin Yu felt that something else was going to happen to her.

At her speed, if she went to one of the empty spaces in the middle, Wu Wanhang might not have noticed anything was wrong.

But here...

Wu Wanhang isn't senile; how could he not remember who was sitting in this seat a minute ago?

It all came down in that one minute!

"Dude, you'd better not..."

Lin Yu decided to give it a try and see if he could save an unfortunate child.

"Shh-"

Su Wanqing pouted her rosy lips and gently placed a finger in front of them.

"Hey classmate, can you do me a favor?"

She lowered her voice and clasped her hands together in front of her chest.

"no……"

Lin Yu wanted to explain further.

"The girl in the last row by the door, please answer this: where were we in the last class?"

Well, it seems her luck wasn't so good either.

Su Wanqing stood up awkwardly, and the other students in the classroom turned to look at her, letting out a series of low sounds of surprise.

"Um...we're talking about that..."

What should I do? This is so embarrassing!

Su Wanqing kept giving Lin Yu meaningful glances, hoping to get some outside help.

"The students next to her shouldn't help her."

It seems hopeless.

Unfortunately, the eyesight of the still young Wu Wanhang was far superior to that of the old professors with their thick glasses that were as thick as the bottom of beer bottles.

The tricks that might fool the old professor wouldn't work on Wu Wanhang.

"What's this student's name?"

Wu Wanhang's voice carried a hint of amusement.

"...Liu Siwen."
