"So remember, what is mechanical energy? It is a general term for kinetic energy, gravitational potential energy, and elastic potential energy, and the formula is E=Ek+Ep"

The female physics teacher, whose glasses were glowing, spoke the stage with her voice pulled out.

Lin Wancongee sat straight and listened very carefully.

Even though she had already previewed this part in advance and completed the exercises, she still copied the teacher's board book word by word in a special notebook.

Her handwriting is beautiful, even if she has drawn a lot of horizontal lines, wavy lines and other symbols on it, the notebook does not look messy at all, but indescribably neat, as if it has a miraculous effect that makes people remember it at a glance.

"The derivation process has been taught, and students who don't understand it will memorize the formula, and the exam will be 100% examined!"

As soon as the teacher said this, the girl revisited the derivation process more seriously, and sorted out the transformation relationship between various energies in her mind.

At this time, she suddenly noticed that her back had been poked, and the person who poked her was naturally Xu Cheng in the back seat.

Annoyed, she must have asked her to pick up pens and erasers, so she didn't care about him.

The girl frowned and leaned back on the table, fortunately she was not as thick as Guo Zining, and her back could avoid the super long distance of that hand.

The effect is also obvious.

The palm behind her really didn't harass her anymore.

This made the girl slowly breathe a sigh of relief, took back her mind that had been gone for a long time, and continued to listen carefully to the teacher's knowledge points.

So what about the law of gravitation, that is, any two objects in nature are attracted to each other, and the magnitude of gravity is on their connecting line, and the point is that big F = big G times. The formula for the exam is worth two points, depending on whether you remember it or not. ”

After listening to what the teacher said, Lin Wancongee flipped through the textbook in disbelief.

One page, two pages.

I turned five pages in a row to see the part that deals with gravity.

It's outrageous!

It's only been a little bit of a distraction, and the teacher has talked so much?!

Fortunately, she has a good foundation.

Although she missed a lot of content after walking for such a short time, she understood it all after a little reading of the eyeboard book.

Presumably the other classmates must be like her.

Just thinking about it, Lin Wancongee felt that her feet under the chair seemed to have been touched by something, so she looked down at the chair.

It turned out to be Xu Cheng's big feet.

Why does this guy have so long legs? Her feet are stretched out in the middle of her feet!

His big feet were still moving, bumping against the girl's little white shoes.

Lin Wancongee looked up nervously and looked around, and found that no one was paying attention, so she turned around and glared at Xu Cheng fiercely.

"What for!"

"This, this."

Xu Cheng lowered his head and lay on the table, relying on the cover of the books raised high on the table, and handed the note in his hand to Lin Wancongee.

The girl ignored him and turned away again.

She knew what he wanted to say without a note.

Hum.

She didn't let him join their camp!

Everyone has already said it.

If you want to go this time, it's a few girls who go together, and it's a pure girls' bureau.

Whoever brings a man at that time will be a puppy.

She doesn't want to be said by everyone that she and Xu Cheng are a pair of dogs and men.

However, this made her little feet suffer, and under the chair, she was entangled by Xu Cheng's big feet, sucked together like a magnet, and couldn't take it off at all.

Xu Cheng used shoes the size of two boats to clamp the position of her ankles, as if locking her inside.

His legs were also strong, clamping her feet so tightly.

From the feet to the ankles and even the calves, almost everything was tightly bound by him.

Lin Wancongee used her other foot to resist, kick, kick his instep, and rub his calf

But it's just useless.

Forget if she can't save the bound foot, it looks like she is actively entangled with him.

There was a slight feeling of pressure tightening in the feet.

Add to that the surroundings of the classroom, the whispers of the students, and the eyes of the teachers and the sound of the lecture.

This makes the girl can't help but feel extremely charming and ambiguous stimulation in her heart.

It seems that she is hiding from all her classmates, teachers, and Xu Cheng behind her in a bright and upright occasion.

Lin Wancongee hurriedly turned around.

In the eyes of other classmates, she has always been a well-behaved girl who does not smile and is full of learning.

If everyone finds out, it turns out that she is this kind of bad girl who steals with Xu Cheng in class, and she may be what to say about her.

Although she never cared about that.

"You see, you see." , Xu Cheng handed over the note again, and Lin Wancongee had no choice but to take it.

Unfolded on the table and looked at the contents of the crumpled note.

"You girls are too dangerous, you need a boy to protect them."

The girl picked up a brush and brushed to write a line.

"You big pervert, we're more dangerous!"

Without turning around, she held the note with her slender fingers and handed it to her back, and soon felt Xu Cheng take it from between her fingers.

His fingers touched her tender little finger as if they were kissing, and the girl blushed again.

She's still wondering.

The two of them, a class president and a school committee, took the lead in passing the note, so that the other students could see it, what should they think?

The impact is not good.

It is true that other students have seen it.

"Look at the class president and the school committee! What about passing the note, can you write down the name and deduct points for the two of them. ”

"Are you two b? The two of them study so well, they must put aside the discussion topic. ”

"Yes."

The notes came and went, and the girls didn't even bother to listen to them.

"Don't be Lin Wancongee, in case there is any beast, aren't you afraid?"

"Even if you run into a beast, can you beat it?"

"In this case, I'll help you refer to the location first, where are you going to camp, and I'll help you search for information to see if there are any more ferocious beasts there."

The girl looked at his handwriting and pursed her lips in thought.

It's okay to tell this guy where the camping location is, right?

If he hadn't been called, he wouldn't have been so shameless as to sneak over by himself.

Well. If she was not careful, she revealed the camping location, and then Xu Cheng shamelessly ran over by herself.

Then she can't be counted as bringing him!

Naturally, it can't be formed that she and Xu Cheng are a pair of dog men and women.

Only Xu Cheng is a dog.

It's her Xu dog.

"The Longmiao Mountain campsite should be relatively safe, it's all demarcated addresses, and my mother took me there when I was a child."

By the time she looked up again, the teacher had already begun to wipe the blackboard full of books to make room for what was to be said next.

Lin Wancongee hurriedly turned the page in a panic, and turned four or five pages in a row before finding what the teacher said.

It was all out of her prep, and it sounded a little hard for her to understand.

He pursed his lips in frustration, his eyes full of resentment.

After school this afternoon, if Xu Cheng doesn't explain this to her.

Then he's tonight.

Don't even think about going home!
