Seeing that the fourth biology class was about to end, Shen Zilu was mostly with Sheng Hailuo and Tan Xiao during lunch time, and Guan Zhengxing could only find an opportunity to repay her money before class.

Holding the money in her hand, she slowly approached her desk, and the biology teacher on the podium was reading the exercises:

"When nerve cells are in a resting state, the distribution characteristics of K+ and Na+ inside and outside the cell are ......" The gaze scanned the class, and Shen Zilu's name was clicked, "What does Shen Zilu choose." ”

Shen Zilu stood up, Guan Zhengxing's hand immediately retracted, "Choose D, the concentration of extracellular K+ is lower than that of intracellular, and Na+ is the opposite." ”

"Well, sit."

'Bell-'

The bell rang after class, Shen Zilu got up and ran to the toilet, it was really not that she deliberately avoided Guan Zhengxing, but the time after the first three classes was taken up by 'Teacher Guan'.

As soon as her buttocks got up, she said a cold 'sit down' in her ear, Shen Zilu slowly turned her face, her eyebrows twisted reluctantly, "...... I went to the toilet, three classes, I didn't go, you are a bit humanitarian, okay. ”

Guan Zhengxing's poker face was as usual, and he said without a tone and frustration: "After memorizing the electrochemical principle of metal corrosion, I will go." ”

"......" the corners of Shen Zilu's mouth twitched slightly. What a genus of gold! What a corrosion!

She was stuck in her heart in one breath and couldn't get up or down, squinting at Guan Zhengxing and said angrily: "It's been three classes, you don't want to go to the toilet?" ”

"Then the structure and properties of the representative substances of various hydrocarbons."

I can't take it anymore. Shen Zilu slammed his fist on the table, bit his lip and said angrily: "...... I don't carry it, I'm going to the toilet. ”

"......" Guan Zhengxing lifted his eyelids and looked over, looking very fierce in a deep look.

Shen Zilu believes that if she takes another step, this crazy guy will definitely add a damn theorem for her to memorize. Fortunately, after a period of getting along, Shen Zilu somewhat understood the character of classmate Guan, he belongs to the soft and not hard, and the soft policy is the most effective.

She retreated and said aggrievedly: "Classmate Guan, I really want to go to the toilet." ”

He didn't mean to make things difficult for her, but he was just looking for an opportunity to pay her back, and as soon as he stretched out his hand, Sheng Hailuo returned to his seat and looked at the two of them, Guan Zhengxing changed his words and said, "Finish memorizing the principle." ”

Poof-Shen Zilu vomited blood.

Let's do it! Who asked Teacher Xiao to contract her to him. Bored began to recite: "Hydrogen ...... produced by the reaction"

Sheng Hailuo looked at the picture in the front row with a sense of joy, one with a straight face like a teacher in ancient times, and a Confucian student who shook his head like a gentleman.

“！” Sheng Hailuo was patted on the shoulder, she turned around, Tan smiled and said, "Don't watch the show, you can't ask me anything." ”

Sheng Hailuo said: "There is another trigonometric function problem that I don't understand. ”

Tan Xiao stepped over the chair and sat directly in Wen Tuoxi's place, "Take it out, for the sake of our predecessors at the same table, I will do something good and good." ”

Sheng Hailuo smiled and happily flipped through the exercise book.

Guan Zhengxing took advantage of everyone's inattention and stuffed twenty yuan into Shen Zilu's hand.

“！？” Shen Zilu was stunned for a moment, looked down at Qian, and then looked at him, his eyes confused and puzzled.

Well, this little fool has forgotten about borrowing his money.

"Why are you giving me money?"

"......" is speechless.

A few classmates next door looked over, Guan Zhengxing retracted his eyes and looked down to read, and Shen Zilu said 'oh' again, it seems that he remembered it.

Shen Zilu put the money in his pocket, leaned over and asked him in a low voice, "Hey, Teacher Xiaoguan, can I go to the toilet after I finish reciting?" ”

Guan Zhengxing got up and said, "Go ahead." ”

He left first, and Tan Xiao 'sighed' in the back, "Virtue!" Relying on the first place in the year, it is awesome. ”

Shen Zilu turned around and scolded him, "Give you sour, if you have the ability, you will also be the first in the year department." ”

"Isn't it, I'll help you hold the grievances, and you scold me?" Tan Xiao's mouth was about to be angry, but Shen Zilu said: "He is my tablemate, and it depends on the owner to beat the dog." ”

Tan Xiao narrowed his eyes, "...... Dog fighting? ”

Sheng Hailuo followed, "Look at the master? ”

The analogy didn't seem right, and the three of them laughed.

Tan Xiao jumped out of his seat and ran out of the classroom, saying as he ran: "I'll tell Guan Zhengxing that you scolded him for being a dog." ”

Shen Zilu was so angry that she chased out, "You dare!" ”

Sheng Hailuo followed behind the two and reminded, "Don't run, it's miserable to be caught by the teaching director."
