I smashed the CP of me and the villain school grass

"Assume that A is an m×n (m<n) dimensional coefficient matrix of the constraint equation system, and its rank is m. B is a non-singular submatrix of order m×n in matrix A (｜B｜≠0), then B is said to be A basis for linear programming problems. That is to say..."

Song Zuan explained the knowledge points in the textbook enthusiastically, but Haidai obviously didn't listen.

On the one hand, these technical terms are indeed too difficult to understand, and Haidai's brain cannot understand them.

On the other hand, the two people next to him stared straight at him, and a layer of cold sweat broke out on their backs, unable to concentrate.

Haidai successfully inherited Song Zuan's cowardly temperament, and he took a cautious look at Jiang Ye.

Shocked by fright, he quickly turned his face back.

Whispered to Song Zu'an: "Master...Jiang Ye has been staring at me, I'm afraid..."

"And your sister, I'm also afraid..."

Song Zu'an looked at the two people sitting not far away with their heads stuck.

They frowned, as if they were staring at a big villain who might steal their children at any time.

Song Zuan couldn't say anything about Jiang Ye, so he looked at his younger sister and coaxed, "Warm, go back to your room obediently. By the way, ask Brother Jiang Ye to tell you a story."

The little girl quickly shook her head, "No, we'll stay here with brother."

"Warm, be good."

"(?ì_í?) I don't."

Jiang on the side couldn't sit still anymore, he took out a textbook from his schoolbag, walked to Song Zuan's left and sat down.

"I don't know this knowledge point either. Teacher Song will explain it to me."

Song Zu'an, who is between Jiang Ye and Hai Dai, is male on both sides.

Ah bah, in a dilemma.

He secretly blinked his big eyes at Jiang Ye, and said coquettishly, "Don't make trouble, can you go home first? I'll come to you after tutoring Hai Dai."

"Then I don't worry about it."

"What are you worried about? He is just my apprentice."

"Since ancient times, between master and apprentice...then there are still few things?"

An An, who understood in seconds, had a blush on her cheeks.

"Haidai is still here, don't say that."

The party at this time, Hai Dai:

who I am?Where am I?what should I do?

The squad leader actually has some knowledge points that he doesn't understand and needs to be taught by the master?

Why was the master's tone of voice so delicate just now?

The squad leader said he was worried, but what did he mean?

I'm even more worried, alright, the big villainous squad leader who messes with Master all day long!

What is it that Master said that he could not say more because I am here?

Master actually has a secret with the monitor behind my back?

I am the closest person to Master, am I not?

Haidai looked at the two whispering people beside him, and muttered aggrievedly: "I was the one who slept in the same bed as Master, and Master still has something to hide from me..."

"What?!" Jiang, who had a sharp ear, also heard this mutter clearly, word for word.

"? (???) Did you sleep with An An? When?"

Song Zuan himself expressed confusion.

He behaves carelessly, and he doesn't necessarily remember what he has done.

He also followed Jiang Ye's words and asked Hai Dai: "When did I sleep with you? Don't talk nonsense!"

Haidai was just muttering to himself, but he didn't expect the two people to react so strongly.

What happened to master and apprentice sleeping together?Besides, we are all boys, so it's normal to sleep together.

As for all the fuss?

He explained with a puzzled face: "It was last semester, on a windy night, Master and I were blocked in an alley by several seniors wearing stars and moons, and then we didn't come home until early in the morning. Did you take it home?"

Having said that, Song Zuan was indeed somewhat impressed.

There is such a thing.

But Jiang next to him was not calm.

An An didn't know how to avoid suspicion, and just lay down with others casually!

unhappy!

"Uh...Jiang Ye, listen to my explanation. I haven't talked to you at that time...you understand? So I didn't think too much and brought Haidai home. I promise, nothing happened between me and him. "

"╮(??ω??)╭Master, why are you explaining this? What else can happen between us?"

Song Zu'an mercilessly looked back at the silly apprentice, "Shut up!"

Then he turned his face to Jiang Ye.

Ask softly: "Are you not angry?"

The change of the two faces can be described as perfect, and the switching of the two tones is also the pinnacle.

Jiang Ye raised his eyebrows lightly, his eyes filled with danger, "No, I'm angry."

Song Zu'an continued to explain softly: "I really didn't do it on purpose at the time. We are all boys, so I didn't think too much about it."

"I'm angry!"

"(?︿??.) Then what do you want?"

Jiang Ye had a cold face, with a premeditated look, and said calmly: "I want you to wear a female body when you do it next time..."

The word "servant" hadn't been uttered yet, but fortunately, Song Zu'an quickly covered his mouth and blocked it.

His cheeks were red, and his brows were angry: "('-')ノ)`-') Don't you pay attention to the occasion when you speak?!"

Haidai behind him stared in shock and opened his mouth wide enough to stuff an egg into it.

"?_?Master, what are you...doing...?"

"Do your homework!"

"Do you need to wear... any special clothes for homework?"

"(?｀⊿′)? Stop asking! Just do your homework!"

Judging from the current situation, Haidai can already conclude——

The squad leader must be coveting Master!

And Master... doesn't seem to object either!

After all, this apprentice paid by mistake.
