School grass, your playgirl girlfriend lost

Chapter 150
"Why is there no value for a tangent of 90 degrees?"

"No matter how I look, I don't see that these two planes are perpendicular!"

"Why should it be greater than zero, but not less than zero and equal to zero?"

……

That's enough.

"Ren Ren." Ren Ruxin took a deep breath, threw away the pen, stood up, looked down at Ren Ren, and said angrily: "You are deliberately playing me!"

Ren raised an eyebrow and looked at her.

"What's the matter?", Mr. Ren's voice came from the door of any room.

Ren Ruxin was startled, she looked towards the door stiffly, took a breath, and called obediently, "Grandpa."

"Hmm." Elder Ren was helped into the study by Shi Ruyue, sat on the sofa, looked at the two sisters and asked, "What's wrong?"

Ren Ren sniffed, his eyes were red, and he looked at Mr. Ren with wet eyes and said, "Grandpa, I'm too stupid, I can't learn anything, and I annoy my sister. I will definitely study hard in the future, don't you?" You're yelling at me, okay, don't be angry anymore, okay?"

Ren Yi grabbed Ren Ruxin's hand and shook it, and Ren Ruxin looked at her in astonishment.

"Ru Xin, you're yelling at your sister." Mr. Ren squinted slightly at Ren Ruxin.

"I."

, Ren Ruxin looked at Shi Ruyue helplessly.Shi Ruyue winked at her, and Ren Ruxin lowered her head, "I'm sorry, Grandpa, I won't do it next time." She was so wronged.

Old Man Ren raised his eyelids, "It's good that you know, she's a bit stupid, but it's not your turn to yell at her!"

Ren Ruxin took a deep breath and gritted her teeth, "Grandpa said so."

Mr. Ren snorted softly, looked at Ren Ren and said sarcastically: "And you, stupid, but you have the nerve to say, are you a pig?"

Ren Yi grinned, "I'm a monkey."

"...", Mr. Ren rolled his eyes to the sky, and got up, "Okay, Ru Xin will teach this monkey well."

"Let's go!", Mr. Ren looked at Shi Ruyue.

"Yes." Shi Ruyue helped Mr. Ren out of the study.

Ren Ruxin looked at Ren Ren unwillingly, "Satisfied."

Ren Yi kicked the chair away, stood up, and looked at Ren Ruxin leisurely, "What do you think?"

Ren Ruxin: "..."

"Heh.", Ren Ren sneered, turned and walked out of the study, stopped at the door, "If people don't offend me, I won't offend others." Looking back at Ren Ruxin, he grinned, "Are you right? Sister Ruxin! "

Ren Ruxin clenched her fists tightly.

——

"Bang." With a sound, the things on the desk were knocked down by Ren Ruxin.

"Why, why, why didn't she die, why didn't she die in that mudslide, why did she come back, and what did she do when she came back."

Ren Ruxin curled up in Shi Ruyue's arms aggrievedly and cried,

"Mom, I can't compare to any bitch, why did grandpa treat me like this? Why?",
Shi Ruyue's eyes were red, she patted Ren Ruxin's back, and comforted her: "It's mom, it's useless, it's mom who's sorry for you, sorry for you."

"Mom." Ren Ruxin choked up and looked up at Shi Ruyue.

Shi Ruyue wiped away Ren Ruxin's tears, "Hey, mom won't hurt you, from now on, you have to listen to mom and do what mom says, you know?"

Ren Ruxin blinked her wet eyes, and nodded obediently, "Yeah."

"What a good child of mother." Shi Ruyue wrapped Ren Ruxin in her arms in comfort, patted her back, and comforted her, with the corners of her lips raised.
