Nian Youyou followed closely behind Su Qianxia and also returned to his seat.

Mu Xichen kept looking at Nian Youyou, and finally Nian Youyou found out.

Nian Youyou pretended to be very ladylike, and looked at Mu Xichen with affection, "Lao Tie, what do you think I am doing?" ”

"I'm sorry." Mu Xichen politely apologized and turned his head.

Nian Youyou: "......"

Why don't you look at me.

"Lao Tie, in fact, I don't mind you...... "Look at me more."

Before he could finish speaking, a very discordant voice interrupted.

The student who disturbed the table stood up and answered the question. The old and old professor assigned Nian Yoyo to answer the questions on the blackboard.

Nian Youyou glared at the old professor and stood up reluctantly.

The people who eat melons are snickering, let you talk to Mu Xichen, and you will be punished!

Wait to be disgraced!

"Isn't that easy?" Nian Youyou doesn't play cards according to the routine, to put it mildly.

"Oh?" The old professor didn't believe it, and touched the white hair on the top of his head that was about to fall out, "Then you answer." ”

"Set x first, and then use the parabola ......" Nian Youyou glanced at the question on the blackboard, and said it easily.

The classmate who just snickered and didn't believe it was mercilessly slapped in the face.

Nian Youyou obviously doesn't learn, how can you answer this question.

This question is very difficult, and some people may not understand it when they listen to the explanation, but she didn't even listen to the lecture?

Jealousy makes me ugly, and jealousy makes me unrecognizable.

Su Qianxia on the side snickered: "Although Yoyo doesn't study, he is very smart." ”

Oh, stupid human.

After listening to the old professor's answer, he kept nodding his head, this kid is really good.

I just don't like to learn, but if I do, I must be very good at mathematics.

Although the old professor thought so, he still criticized her for the sake of face, "In the future, you are not allowed to talk in class, and you can't disturb the same table, do you hear me?" ”

"Oh." Nian Youyou agreed, and looked at Mu Xichen in the next second, "Lao Tie, let's talk about life and ideals after class." ”

The old professor who originally thought that Nian Youyou had promised to come down: "......"

Today's children are really disobedient, and one session is not as good as one session.

"You sit down first." The old professor touched his beard and couldn't say anything.

As long as he doesn't talk in class, he can't care what he does after class.

Mu Xichen has been smiling, this girl is really ......

Nian Youyou saw Mu Xichen's smile and laughed along.

Lao Tie's smile is too good-looking, and her girlish heart is rippling when she sees it.

……

Because Nian Youyou threw a stool in class, he was punished by the exterminator for a whole week and cleaned the toilet.

Nian Youyou pulled Su Qianxia on his back.

"You go and sweep it yourself, I don't want to go." Su Qianxia refused to clean the toilet.

Nian Youyou didn't care whether Su Qianxia agreed or not, and directly carried Su Qianxia away.

Su Qianxia, who was carried, was in tears, how could she have such a violent best friend.

Can I return an item? Postage she out.

"Is it a girlfriend?" Nian Youyou asked coldly, like a guinea pig looking at an experiment.

Su Qianxia replied tremblingly, "It should be...... Right? ”

"It's my best friend who will help me clean the toilet." Nian Youyou really didn't have a good heart.

Nian Youyou looked around and said, "I've calculated, I'm going to brush the toilets of two buildings, I'll brush the toilets in that building, and you brush this building." ”

"Remember to go back to the classroom to gather after brushing, don't run blind." Nian Youyou said to Su Qianxia like a child.

"Okay, got it."

Nian Youyou ran away with the toilet plug.

Su Qianxia looked at the toilets one by one, and the whole person was not good.

There are eighty toilets on each floor, and there are three floors in total, so you have to brush two hundred and forty toilets.

So much, do you want to let people live.

The exterminator only allowed the toilet of the women's toilet to be cleaned, and the one who removed the men's toilet was one hundred and twenty.

In the end, Su Qianxia resigned herself to putting on gloves and brushing the first toilet.

As soon as she entered, a figure swished in, and with a bang, the door was shut.
