Li Shunan raised his eyes and glanced at the blackboard, raised his chin slightly, and spoke slowly: "...When x is equal to L/2, EK reaches the maximum, and x is equal to 1/2at12...t1 is equal to... The answer is 0.014s."

His speed of speech is neither rushed nor slow, always giving people a calm and unhurried calm, as if he is in control of the overall situation.

Just like now.

Even Jiang Lingzhi didn't know where Brother Weiwu came from.

He opened his mouth and reported a series of answers.

A drop of sweat slid down Jiang Lingzhi's forehead, shouldn't he be talking nonsense?

But……

After he finished his answer, there was no quiet sound in the classroom.

Even Brother Weiwu stopped talking.

Howie's forehead twitched twice.

He was a little annoyed to see them chatting so happily just now.

Jiang Lingzhi had nothing to do with it. He often got perfect marks in exams, so he didn't say anything.

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

Although others say that this is a thorny student, he doesn't believe in this evil, so he wants to take the opportunity to show his majesty.

did not expect……

Hao Weiwu was silent for two seconds, cleared his throat, and said bravely: "So, the new classmates are still very good, sit down, even if you are in class in the future, you should still listen to the teacher and discuss discussions. Time, you know? Well, let's look down..."

The crowd suddenly cast a look of admiration in the past.

Tsk, tsk, tut!

The big guy is awesome, even the mighty brother is eating turtles here!

Worship! !

Li Shunan lowered his eyes and sat down loosely.

Jiang Lingzhi leaned over, looked straight 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's lecture? !

Li Shunan raised his eyes, the girl turned her face sideways, he could see the tip of her nose upturned, and he 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? !

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

Jiang Lingzhi: "..."

A bunch of formulas are written on the blackboard.

Okay, it's a bit of a test of your eyesight.

Jiang Lingzhi felt wrong again: "Then how do you know the answer?"

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

Jiang Lingzhi lowered his head and glanced at the test paper. The place where his fingers were clasped was the question the teacher said just now.

What he just said was exactly the same as what he wrote.

Oh, it really is.

However, when did he read her test paper?

Jiang Ling knew half of it, so she raised her hand and placed the test paper between the two: "Let's read it together."

Li Shunan sat on the side with his eyes down, staring at the girl's test paper, the number of full marks was striking.

Gee, my little roommate is very good.

He leaned back, his attitude was full of laziness, and he supported his head with his hands, looking tired and tired.

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

"Well," Li Shunan looked up at her, and responded calmly, "What?"

Jiang Lingzhi nodded: "Then go to sleep, Lao Ban probably won't call you again. He won't allow himself to fall in the same place twice."
