Mobei opened Ji Yunhan's math book, and was about to talk about it to Shangguan Yan......

"Ji Yunhan ......"

Mobei pushed the glasses on the bridge of his nose, gritted his teeth and said, "Don't you want to live anymore??? ”

Shangguan Yan didn't pay attention to the scribbles on the book, but when he heard Mo Bei say this, his eyes were on the part that Mo Bei deliberately blocked with his hand......

"Huh? Help me finish it first, and then you'll settle accounts with him. ”

Mobei listened to Shangguan Yan's words and took a few deep breaths: "Whew, I'm calculating the general ledger later, let's look at the question first......

Because there are often younger students in the student union who ask him to make up for classes, he knows very well where the math class in the first year of high school is now.

"This sum of the first n terms of S, you look at its known conditions, it has told you some sequences, you first find its tolerance......"

Shangguan said: "Ah~ Then you can calculate the tolerance according to the formula, because it has already told the first item." ”

……

"Teachers, students, class—"

As soon as Mobei closed the book, the prepared bell rang.

"The time is just right, thank you, president, I'll go first."

"Okay."

……

After Shangguan Yan thanked him, he took a pendant that Mobei gave him before and left the student union.

"What is this pendant...... Why is there a strange energy fluctuation on it......"

Shangguan Yan walked towards the teaching building not far away unhurriedly, his eyes slightly lowered and he muttered to the wing pendant in his hand.

Because Shangguan Yan walked too leisurely, and the person was still hanging his head, he was stopped by Zhou Sheng on duty again, but it was still the two who met in the first two classes.

"No, it's you again......"

The boy looked at Shangguan Yan's face was a little distorted.

"Hey, you shut your mouth first."

The girl next to her slapped the boy a few times, and then smiled and said, "Classmate, you should have come out of the student union again, show me your pass." ”

Shangguan Yan pursed his lips with a smile: "The president gave me this, and he didn't give me the companion card." ”

He picked up the wing pendant in his hand and showed it to them, but the two students on duty were shocked for a moment when they saw it.

I'll go, and the president will give him such a precious place?

"Well, classmate, you can go in, remember to hurry up, because the second bell is going to ring, and the pendant needs to be kept, well, by the way, what's your name?"

The girl told Shangguan Yan, and finally remembered that she didn't know Shangguan Yan's name......

"My name is Shangguan Yan...... Belch...... Does this pendant do anything? ”

Shangguan Yan was a little hairy by these two Zhou Sheng.

"It's useful, it's useful, anyway, you just need to remember that this pendant is very important, very important, and it must not be lost."

"Oh......"

"Okay, let's go in, let's go first."

With that, the girl pulled the boy and walked quickly in the direction of the student union.

Shangguan Yan, who was confused, looked at the increasingly blurred backs of the two and felt strange in his heart.

"What the hell is this thing for...... How did the girl and the boy look at this thing with strange eyes......"

If he was not mistaken, then the pair of Zhou Sheng's eyes should have flashed with respect after seeing the pendant in his hand, and listening to their tone, they seemed to know what this thing represented, and they seemed to be even more surprised and strange......

"Forget it...... I can't think of a reason for it......"
