Li Shunan raised his eyes and swept the blackboard, raised his chin slightly, and said unhurriedly: "...... When x is equal to 2/2 L, EK is maximum, and x is equal to 1/2at12...... t1 equals ...... The answer is 0.014s. ”

His speed of speech is not hurried, and he always gives people a calm and unhurried calmness, as if he is in control of the overall situation.

Like now.

Even Jiang Ling didn't know where Brother Weiwu was talking about.

He opened his mouth and gave a series of answers.

Jiang Lingzhi slipped a drop of sweat on his forehead, he shouldn't be talking nonsense, right?

But......

After he finished answering, there was no sound in the classroom.

Even Brother Wei Wu stopped talking.

Hao Weiwu's forehead twitched twice.

He was a little annoyed when he saw them chatting so happily just now.

Jiang Lingzhi just forget it, he often has a full score in the exam, so he doesn't say anything.

However, this new classmate didn't give him the class teacher at all!

Although others say that this is a thorny student, he does not believe in this evil, so he wants to take the opportunity to establish his majesty.

I didn't expect ......

Hao Weiwu was silent for two seconds, cleared his throat, and said stubbornly: "So, the new classmates are still very good, sit down, even when you go to class in the future, you still listen to the teacher, and the discussion will also divide the time, you know?" Okay, let's move on......"

Everyone immediately cast a look of admiration.

Tsk, tsk, tsk!

The big guy is awesome, even Brother Weiwu eats turtles here with him!

Worship!!

Li Shunan lowered his eyes and sat down casually.

Jiang Lingzhi leaned over, looked ahead, and asked in a low voice, "How do you know where he came from?" ”

Wasn't he talking to himself just now, how could he still hear the teacher lecture?!

Li Shunan raised his eyes, the girl turned her face sideways, he could see the tip of her upturned nose, and casually threw out two words: "Guess." ”

Jiang Lingzhi: "??? ”

Jiang Lingzhi turned his head and stared at him blankly.

How did you guess this, tell me, there are so many questions on the test paper, how did you just guess this question?!

As if sensing what she was thinking, Li Shunan raised his chin: "He didn't write half of the formula on the blackboard. ”

Jiang Lingzhi: "......"

The blackboard is densely packed with a bunch of formulas.

Well, it's kind of a test of eyesight.

Jiang Lingzhi felt that it was wrong again: "Then how do you know the answer?" ”

Li Shunan stared at her for a while, his eyes were a little playful, and he raised his hand and tapped twice on her test paper: "Didn't you write here?" ”

Jiang Lingzhi glanced down at the test paper, and the place where his fingers were buckled was the question that the teacher said just now.

What he just said is exactly what he wrote.

Oh, really.

However, when did he read her exam papers?

Jiang Ling was half-understood, and raised her hand to put the test paper between the two: "Let's read it together." ”

Li Shu sat on the south side, lowered his eyes, staring at the girl's test paper, and the number of full marks was very eye-catching.

Tsk, the little table is very good.

He leaned back, his posture full of laziness, his head propped up with his hands, and he looked tired and tired.

Jiang Lingzhi looked at him and asked in a low voice, "Are you going to sleep again?" ”

"Hmm," Li Shunan raised his eyes to look at her, and responded unhurriedly: "What?" ”

Jiang Lingzhi nodded: "Then you go to sleep, the old class shouldn't order you anymore, he won't allow himself to be planted twice in the same place." ”
