Because it was just a bruise, the promise came back soon.

She sat at the desk under the lectern, listening to the teacher lecture in front of the blackboard, in a trance.

These contents are obviously known and mastered by her, but in a completely unfamiliar environment, in an unfamiliar classroom, there is no sense of familiarity at all.

I even had the urge to cry, and for the first time I felt lost......

In this unfamiliar environment.

What's next for her?

"Promise classmate, you come up and do this question."

The math teacher tapped the blackboard with his whip, reflexively stood up from his position, and shouted "Here!" ”

The class burst into laughter.

"Hahaha, how old are you and you still raise your hand and shout, it's not a shame."

"It's like a child."

"Teacher, what do you choose her for, she doesn't know anything except chasing Gu Ze all day long to confess."

"He only has Gu Ze in his eyes, where will he still study."

Everyone, you say a word, and among them, Zhang Tingting and the others are the most happy, trying in vain to attack Xu Promise.

This is a call back to God for the promise.

"Isn't it just a math problem? Look at the one who abused you, my sister will go up and teach you now. ”

Xu Promise walked up to the podium with great dignity, and he looked like a strong man with a broken wrist.

But soon, she couldn't laugh anymore.

【Ding! If the host violates the original "no ink on the chest" persona, please stop immediately, otherwise you will be punished by "turning back to the shore". 】

- And what kind of punishment is that?

The next second, I felt the sound of someone tapping on the wooden fish next to my ear.

"Knock knock" seemed to knock into her brain, giving her a splitting headache.

Influenced by "turning back to the shore", the action of promising to answer the question on the blackboard with chalk is a meal.

In the eyes of other students, she just can't write.

Look silly.

"Cut, I thought she would do it."

"You don't know the promised grades, the last in the class, do you think she will do this function problem? The first place in our class is enough to choke up. ”

"Is it really a swollen face to fill the fat man, thinking that you will write after a trip to the podium?"

"Come down, don't be ashamed."

"yes, let's get down here!"

They shouted, but promised not to hear them now.

The ears are full of "dong dong" wooden fish sounds, and some incomprehensible Buddha sounds.

My head is about to explode.

【…… Go down, why be so uncomfortable? 】

- Nope! I must write it out!

Promise gritted her teeth, she couldn't just admit defeat like this, she couldn't keep being so bad.

She held the chalk in her hand and quickly wrote on the blackboard: "Let A and B be two non-empty sets of numbers, and if we follow some correspondence rule f, for any number x in the set S......"

When he finished writing the topic, he immediately dropped the chalk and left the podium as if fleeing, returning to his place.

That headache is just a little better.

"Teacher, did she do it right?"

"Do you see how she just ran away, like someone who did the right thing?"

"Hahaha, too!"

The math teacher also finished reading the question, and slammed the podium with his whip, making a screeching sound.

"Alright, shut up!"

"............" the class fell silent.

"This question, promise the students to do it right, and this method is also very simple, you can refer to it, I will explain it now."

"What? Did you get it right? ”

"Impossible, teacher, promise that she won't write at all."

"Did the promise get it right? Teacher, I think you should change the power of your glasses. ”
