After digressing for a while, Bai Lu opened the textbook and showed Qin Conghuai a few example questions that had been randomly outlined. @

Qin Conghuai lifted his glasses, his eyes moved from Bai Lu's body to the textbook, and Bai Lu's eyes began to look at his desk, now it is not like in 2015 that every classroom has computer projectors and other auxiliary electronic equipment, and at the same time, each teacher is also equipped with a personal computer for modern teaching.

In 1994, there was only paper and pen in the teacher's office, and everything was still in the manual stage, so Qin Conghuai's desk only had spread out lesson plans, teaching books, students' homework books, personal water cups, etc., which were very normal furnishings.

"This question...... Qin Conghuai said loudly, pulling Bai Lu's attention over.

Bai Lu leaned forward a little closer to see the small print in the textbook.

"This question is an introduction to algebra, mainly using a few formulas, Xiaolian, do you remember the formulas that your teacher Chen taught before?"

Bai Lu understood the example questions in the book "Formula, ......", but she was really stunned for a moment when she suddenly pulled out a certain detail to ask, and in Qin Conghuai's eyes, it meant that she didn't remember the previous knowledge points, which was exactly what he expected.

"Xiaolian, several important formulas of algebra are the key to solving problems, if we can't even remember the formulas, then even the most basic problems can't be done. ”

Isn't this nonsense, Bai Lu complained in her heart, if it wasn't the key to solving the problem, could it be called an "important" formula, but she still nodded humbly and teachably.

"Do you think this question is a squared difference formula, or a squared formula for the difference?"

Bai Lu's mind was not on the topic at all, and suddenly he heard the question of "square difference" or "poor square", which was like playing word games. For her today, the knowledge points in the first year of junior high school are not as familiar as the advanced mathematics of college differential calculus derivatives and other content.

"Uh... Is it a squared difference formula?"

"That's right, you look at the problem, we calculate the result 13 according to the A value and B value given by the question, through the squared difference formula, and then use 13 to subtract 7 from the first sentence of the question. The end result is obtained. ”

(#‵′) Even if she picks it casually, she won't ask such a simple question.

"Oh, that's right!" Bai Lu said in an accent. It seems to have really dawned on me.

"Got it?"

"Hmm!" is so simple, it's too fake to say that you don't understand.

Let's look at the next problem, assuming that m, n is an integer, and n=3. 36 divided by m and multiplied by 7 minus n equals 18, ask how much m is equal to?"

Bai Lu reluctantly calculated on the scratch paper on the side. Once an algebraic list is made, it's easy to solve.

Just as she was about to say "m=12", Bai Lu noticed that Qin Conghuai's gaze was staring at her...... In the front chest, if you don't know anything, you just think it's a natural sight. But when Bai Lu knew the truth, he felt that this sight was like a sticky stinky ditch sludge, which was indescribably disgusting.

Bai Lu shrank back. Turned around and pretended to rummage over things, and carried the schoolbag from behind in front of him. Pretended to be excited to solve the problem: "Teacher Qin, is m equal to 12, right?"

Seeing Bai Lu blocking the front of him with his schoolbag, a trace of disappointment flashed in Qin Conghuai's eyes, but he quickly covered it up: "Yes, it's 12, it seems that Xiaolian you have a good grasp of the content of this piece." ”

"Teacher Qin~" A female voice came, it was the pregnant female teacher who taught foreign languages, she said: "Teacher Qin, Darling has come to pick me up, then let's go first!"

Bai Lu thought silently, Darling is dear, worthy of teaching foreign languages, even her husband has to pronoun it, I don't know if Smecta will appear.

After the teacher who shouted Darling left, only Qin Conghuai and Bai Lu were left in the office, Bai Lu hadn't reacted yet, but from Qin Conghuai, he was obviously "explaining the topic", but he got closer and closer-

Ahh

Bai Lu had all kinds of disgust in her heart, and her mind kept coming up with the scene of Qin Conghuai violently infusing customers on the night of thunderstorms on customer order materials, and now, the violent beast was sitting unharmed in front of her, and she was also "lecturing" in a high-sounding manner.

"Well-dressed beasts" refers to people like Qin Conghuai!

Pretend to accidentally touch your hand and arm and pat your shoulder...... All kinds of small actions are intimate between couples, and caring for the loving elders, but Qin Conghuai is always obscene, and he can do it to female students who are not yet adults, how distorted this psychology is!

Bai Lu's endurance is limited after all, and he can't stay any longer knowing that he will be rubbed with oil by the salty pig's hand.

"Ouch..."Bai Lu suddenly clutched her stomach and screamed.

"Xiaolian, what's wrong with you?" Qin Conghuai said with concern.

"I ...... My stomach hurts a little. ”

"Is it cold?" Qin Conghuai actually grabbed Bai Lu's shoulder with one hand, and the other hand was about to poke into Bai Lu's belly, which frightened Bai Lu.

"Well, it seems to be a cold!" Bai Lu put the book back in her schoolbag and hurriedly got up: "I'm sorry Teacher Qin, I... I have a stomachache and ...... first Let's go first!"

When Bai Lu stood up, he saw that the entire office was empty, and it was estimated that all the teachers had gone to lunch, so there must have been no other students coming to ask questions at this time.

"Does it matter?"

Even if Bai Lu stood up and put on his schoolbag and was about to leave, Qin Conghuai didn't let go, but hugged Bai Lu as if he was concerned: "I'll send you to the infirmary to have a look!"

Qin Conghuai's strength pinched Bai Lu's shoulders a little painfully, you well-dressed beast is a pervert, let go of me!

Bai Lu didn't break free from Qin Conghuai's shackles with all her strength, her mind was full of thunderstorms and tyrannical scenes at night, interspersed with chaos, and a layer of fine sweat appeared on her forehead.

Qin Conghuai shouldn't want to use force in the school office, right!?

It's noon now, even if the teachers go to eat, it will only take a while, and the office doors and windows are wide open, Qin Conghuai won't be unscrupulous to this point, right!?

And Qin Conghuai, who was holding Bai Lu in the name of care, was very happy in his heart, the young female student made him feel a sense of vitality, his tentacles were full of softness, like a soft little animal, and it was also that kind of little milk cat and rabbit, so that he couldn't suppress the fierce beast in his heart, and wanted to ravage it fiercely, and then eat it into his belly......

It's just that this kitten doesn't seem to be very obedient.

As Qin Conghuai didn't even realize that his knuckles were getting stronger and stronger, Bai Lu's breathing became short, and the fear of the original body also conveyed a prayer to her spirit body at this time-
