“…… Well, I'm in. Pei Bai felt that his voice trembled a little.

"Did you understand the third question I just told you? In fact, the principle is more complicated to understand, you just need to know the result, and you can use it directly when doing the problem. ”

I'll go! Can you not be like this, hey, you call people so casually, it's easy to scare people to death!

"Oh, I'll think about ...... again"

Pei Bai muttered, then seized the opportunity to take a look at Ding Li's bedside and found a few strands of hair.

Then I went to her desk to take a look, and it happened that there was a comb there, Pei Bai picked out a few hairs that he looked at and had hair follicles, and then knocked the collected hair into a square plastic bag he had prepared, and then closed the seal.

After everything was done, she secretly returned to her place, picked up the pen and began to work on the problem.

As soon as he started reading the question, Ling Lan, who had washed his hands, came out, and asked as he walked, "How is it, are you done?" ”

Pei Bai smiled at her apologetically: "I'm still ...... I really don't know much. ”

Ling Lan sat next to her again and gave her a lecture.

……

When he went back in the evening, Linglu was reading a book on the sofa.

Pei Bai had a tired expression on his face, leaned over Ling Lu's stomach, and muttered while leaning on: "Damn, don't your waist be so thin, you don't have a stomach, it's not comfortable at all." ”

After saying that, he took a cushion and put it next to Zero Lu, and then moved his head to the pillow.

She squinted at the cover of the book in Ling Lu's hand, "Contemporary Astrology Research", and the energy that had just been drained seemed to be squeezed out a little more.

"You...... Is this preparing to be a goddess? ”

"Hey, I won't fail the course, just take a look."

"You can occupy one for me, so let me see if my future husband is handsome." Pei Bai closed his eyes and said mischievously.

"A boy who can be worthy of our Miss Pei is naturally handsome."

"How handsome?"

When Pei Bai asked this question, Ling Lu didn't know why, and Xiang Ju's appearance drifted through his mind - he was sitting at the door that night, and it seemed that his voice was faintly saying that he was hungry...... Actually, how do you feel that when it's not a killing decision, Xiang Ju looks better?

Seeing that Ling Lu didn't speak, Pei Bai took out a plastic bag from his bag with his eyes closed, and said, "I'm tired today, I'm just going to get a strand of hair, so Ling Lanfei took me to give me an example question...... No, this is a whole half of the example problems of high mathematics, and to this day, my head is still buzzing, what are the limits, unary differentials, indefinite integrals, multivariate differentiations, and two-triple integrals...... God, I felt like all my math cells were forced to activate and then die out in an instant. ”

As soon as Ling Lu heard this, he felt that something was wrong: "Ling Lan gave you a lecture?" Are you still talking so seriously? ”

Originally, Pei Bai felt that today's Ling Lan was a little strange, but he was overwhelmed by Gao Shu, and he forgot all about it all at once.

At this time, Ling Lu reminded her, and she remembered it again.

She sat up from the sofa and said vigilantly, "You also think Ling Lan is very abnormal like this, don't you?" And she didn't look half angry when she saw me, but joked with me, as if we had known each other for a long time and had a good relationship. ”
