Seeing Gu Zhesi talking eloquently on the podium, Xue Qiao's face turned red, and he denied it coquettishly: "What are you talking nonsense about!" Senior Gu is so good, how can he like me, don't talk nonsense in the future. ”

"Oh." The tablemate nodded with a smile, supported his chin with his hand, and continued to appreciate Gu Zhesi on the podium calmly explaining the content of this lesson.

I can't help but sigh.

It's so handsome, even if it's handsome, how smart is it, the key is that the family is still so rich, it's really a tyrannical thing!

Looking at Gu Zhesi, who was standing on the podium and seriously explaining the content of mathematics, Lang Siyu was also shocked by him.

I didn't expect this guy to have such a side.

It turns out that the serious man they said is the most handsome, and it's true!

I don't know when Nuan Yang sneaked into the classroom, naughtily leaned on Gu Zhesi's body, and put a layer of warm soft light on his white sweatshirt.

The clothes are pulled up to the arm, revealing a fair and strong arm, giving people a capable taste.

The facial features that are carefully carved like a ghostly axe make people look a little fascinated.

"As follows from these two inferences, there must be no inverse function for even functions, and there is not necessarily an inverse function for odd functions."

His voice struck at her heart like a clear spring.

"Then Lang Siyu, please get up and answer, if there is an inverse function of an odd function, then its inverse function is ......."

Xue Qiao was slightly stunned, and glanced at Lang Siyu, who was still stunned, in disbelief.

Isn't Lang Siyu a freshman who just transferred? How could Senior Gu know about Lang Siyu?

Could it be that they had known each other before?

Or is it just a delusion on her part?

Gu Zhesi propped his hands on the projector table, leaning lazily on it, and raised his eyebrows to look at Lang Siyu.

I was actually distracted in class, when I was what, the air!

In an instant, all eyes followed Gu Zhesi's sweeping towards Lang Siyu.

Lang Siyu was stunned, I'm damn!

I actually forgot what kind of person this guy is, and I was still obsessed with his beauty just now, what the hell.

So what did he just ask?

Lang Siyu hurriedly looked at Li Li, hoping that she could give her a hint.

But Li Li looked at her with a joke in his eyes.

Lang Siyu was stunned.

She really has a goldfish memory, she had a conflict with Li Li just a second ago, and now she is waiting to see her jokes!

If you are really sick, you rush to the doctor.

The door of the head is caught by the door before he asks her for help.

Forget it, on your own!

"I'm sorry, Senior Gu" Looking at Gu Zhesi's gloomy eyes, Lang Siyu swallowed his saliva, and after taking a deep breath, he stared at Gu Zhesi with a deadly expression, and added again, "Can you repeat the question just now?" I forgot. ”

“……”

The rest of the people in the classroom watched the show, and some covered their mouths and didn't laugh, in short, each family had their own expressions and psychology.

And after Gu Zhesi listened to Lang Siyu's words, a wave of anger rushed to his head, and he was so angry that he almost couldn't control himself and wanted to smash the chalk in his hand towards Lang Siyu's head.

Lang Siyu touched his nose in a daze, stalked his neck, raised his head, and looked directly at the information left by Gu Zhesi on the blackboard.

Looking at the frightened Lang Siyu, Gu Zhesi suddenly felt a trace of unbearability somewhere in his heart.

Or "forget it".

But if it is forgotten, will it hurt her self-esteem!

Forget it, I'd better remind her!

Gu Zhesi coughed lightly, stretched out his hand and pointed to the deduction steps on the blackboard again, "If ......"

Before Gu Zhesi could say "Qi", Lang Siyu slapped him in the face with a sentence of "I know".

Gu Zhesi's heart jumped, and suddenly the urge to hit someone became even more violent.

"Even functions must not have inverse functions, odd functions do not necessarily have inverse functions, and odd functions have inverse functions, then its inverse function is odd functions, right?" Lang Siyu replied with a smile, and the two pear vortices on her well-behaved face rippled shallowly.

Gu Zhesi was stunned, then quickly removed the abnormality, cleared his throat and replied lightly: "Hmm"
