Differentiate into omega in the normal world

There was a long silence on the phone.

Chen Lang should hang up if he can't hear the voice.

However, things backfired. Chen Lang patiently prepared him mentally, and then said, "Speaking of Song Chen, I can hear your breathing."

Song Chen subconsciously held his breath.

The other side paused for a moment and said, "Don't hold your breath."

Song Chen felt aggrieved and snorted, "What's the matter, I'm busy."

"Yes, I just found a math paper in my schoolbag, and it only scored 145. I feel a little strange..."

"What's strange, of course you did the wrong question, and you thought the teacher gave you a wrong score. Besides, 145 points is pretty good, do you think you can get a full score back then?"

"Yes, yes, 145 points is pretty good." Chen Lang followed his words sincerely.

Yo, I'm pretty human today, and I didn't say anything to refute.

Song Chen, who had successfully pissed off Chen Lang, was in a better mood, "Why did you come to me, do you want me to explain the wrong question to you?"

"Alright." Chen Lang held back his laugh and asked, "But I want to ask you how many points you have first."

"Of course I'm—" Song Chen suddenly stopped, feeling something was wrong.

Math paper?

Didn't he remember that Chen Lang got full marks?

Song Chen faintly had a bad premonition. He rummaged through his schoolbag and found a test paper in the middle.

mathematical.

out of 150

Name: Chen Lang.

Song Chen's head buzzed, I must be dazzled.

He closed his eyes, meditated for three seconds and opened them, still the same scene.

"How much?" Chen Lang on the other end of the phone asked, a little laughter seemed to escape from his throat.

It was very light, but Song Chen heard it.

He gritted his teeth and said, "Chen Lang, you're playing tricks on me, you already knew about it, right?"

Fortunately, he thought he was here to ask him a question, but it didn't make sense after thinking about it. When did the relationship between the two get so good?

dizzy.

Hearing Song Chen's gnashing of teeth, Chen Lang finally laughed out loud, stopped laughing for a few seconds, and said before someone hung up, "You know what, I didn't say that this test paper is mine. Besides, 145 points is not very good, how can I return to full marks."

He returned Song Chen's words to Song Chen intact.

As soon as Song Chen exerted force, his thumb poked a hole in the test paper, and he calmly licked it.

If Chen Lang was present, maybe he could smell some milk fragrance again.

"I think you have the right idea behind the big question, that is, the decimal point of the data in the middle..." Before finishing speaking, the phone beeped to indicate that the voice call had ended. Chen Lang kept smiling, picked up the pen and wrote down the correct process Then, take a photo and send it to Song Chen.

Chen Lang: Help you change it.

I also posted a cute meow meow emoticon package.

Of course Song Chen didn't reply, Chen Lang could almost imagine how angry he was now, maybe even the smell of milk came out.

After thinking about it, Chen Lang smiled happily again.

The next day Song Chen came to the school early and met few people along the way, and he was also the first to enter the classroom.

Taking advantage of no one, he stuffed the test paper with a hole in it into Chen Lang's drawer.

Seeing the wristband on his wrist, Song Chen frowned in distress, and finally pulled his sleeve to cover it.

Stupid batch.

Tell you to play me.

I'll give it back to you a few days later.

Song Chen sat back in his seat, took out the sandwich Aunt Lin had prepared and started eating.

He took a bite and cursed Chen Lang again.

If it weren't for him, I wouldn't have got up so early, and returned the test papers before everyone came.

As time passed, the number of people in the school began to increase, and students came into the classroom one after another. Zhou Ning saw Song Chen at a glance and asked, "Why did I go out so early today? I went to your house. Aunt Lin said you had already left." gone."

"Come here and recite the words, dictate today."

"Is there such a thing?"
