My Sister is a Bit Ruthless

  Chapter 151 Uncomfortable

  "...Using the regression equation to perform statistical control to specify the change of the Y value, and to achieve the goal of statistical control by controlling the range of x.

If the regression equation between the concentration of NO2 in the air and the flow of cars has been obtained, the concentration of NO2 in the air can be controlled by controlling the flow of cars..." Under the bright light, Jin Feifei is gently answering questions about the rain, black eyes Shines in rational luster.

  Siyu also listened carefully, and then immersed in her homework...

  The state of obsessive and selfless learning gives Siyu an extraordinary charm. Jin Extraordinary feels that the silk rain at this time is more beautiful than ever...

  Binjiang Road, a high-end car is speeding past Huaxiang Lane.

  A young man in the co-driver suddenly shouted: "Brother Cha, stop."

  The boy is Liu Xudong.

   Liu Xudong got off the car and saw a pretty lady on the side of the road preparing to walk towards Huaxiang Lane.

  "Zhiqiu——" Liu Xudong greeted the person he wanted to provoke in the previous period.

   "It's you, Xudong." Ye Zhiqiu saw Liu Xudong and suddenly felt a little sad.

  "Where are you going?" Liu Xudong asked.

   "I will go to see Siyu in'Beauty's Appointment'."

   "What are you going to see her doing?"

   "She met with Jin Feihua today, I am a little worried about her."

   Liu Xudong laughed, as if he had heard the funniest joke in the world.

  "Worried? Are you worried about the rain?"

   "Why, is there a problem?"

  "Zhiqiu, why don't you worry about Jin Feihua? Unless that girl loves money, twenty Jin Feihua can't help but a cold rain."

   Liu Xudong said, but he was still surprised that Ye Zhiqiu was worried about Leng Siyu.

  In Liu Xudong’s cognition, Ye Zhiqiu is vain and selfish, and has a strong sense of class. She used to look down on Leng Siyu and disdain to be with Leng Siyu.

  Don’t worry about Leng Siyu, even if you can say a few words peacefully with Leng Siyu, it’s difficult.

   "Then I won't go to see her, I'm going back." Ye Zhiqiu slowly turned and walked back.

  "Zhiqiu——" Liu Xudong suddenly stopped Ye Zhiqiu.

   Ye Zhiqiu turned around, staring at Liu Xudong, "Is there something wrong?"

   "I will send you to you." Liu Xudong said.

   "No, thank you. Not a few steps away." Ye Zhiqiu politely refused, and then walked along the sidewalk on the street.

  The figure from the back was a bit depressed.

   Liu Xudong said "Let's go" after getting in the car.

   Chanan started the car and the wheels rolled forward.

  Ye Zhiqiu’s figure became clearer and clearer, and gradually blurred in the rearview mirror...

   "It's beautiful," Chanan said.

   "School tweed," Liu Xudong smiled, "The singing is also beautiful."

   "Then don't you invite her to sing a few songs?"

   "Someday, I have to go back to catch up with homework today."

   "Are you still doing homework?"

  "You can pick one for me who can maintain good grades without doing homework! Xia Pengfei has such a high IQ, he still has to do a lot of training.

  Xueba is practiced, not blown out! "

"just kidding!"

  ……

  Siyu finished a math paper and looked at the time it was too late, so she said to Jin Feifan, “Extraordinary, it’s a bit late, I want to go back, I have to go back to do political geography homework.”

   Jin Feifan smiled grandiosely, “Okay, I’m fine, you didn’t even drink your coffee, just patronizing the questions.”

  Siyu picked up the coffee and poured it into her stomach like a drink. After drinking, seeing Jin Feifei staring at herself in a daze, she stupidly asked: "Did I drink too quickly?"

   Jin Feihua said gently, "It's natural and free and easy, mainly because I am afraid of choking you..."

   "Waitress, pay the bill." Siyu raised her head and beckoned a waiter.

  "This little gentleman has already paid." The waiter came over and answered with a smile.

"How much?"

   "One hundred and sixty yuan."

  Siyu immediately frowned, took out the phone to unlock and opened WeChat, "Extraordinary, WeChat! I'll ask you, this is a matter of principle."

  Jin Feihua knew that Siyu was serious, and didn't want to lose big because of small mistakes, so he gave out the WeChat account.

  Siyu finished the transfer, put away the test paper and stood up, "Then I will go back."

  Jin Feifan accompanied Si Yu out of the coffee shop, Si Yu said apologetically: "She said that she invited you to have coffee, but she didn’t speak with you. She asked you to help me with the topic, sorry."

   "Believe it or not, I am really happy tonight."

   "Uh, let's go."

  Silk rain's free and easy back disappeared in the blink of an eye under the city lights.

   "A girl like lightning!" Jin Feihua sighed and left.

  ……

  Two people walked out of a certain shadow, Xia Pengfei and Liu Xing.

   "Why avoid her?" Liu Xing asked.

   "She wants to know that I am following her, she must not kill me?" Xia Pengfei said, "Now let's go, I'll buy you a cup of coffee. I can't let you go for nothing."

  ……

  Siyu returned to Room 0101, Unit A, Building A, Fenghuang Community, and saw the two children still using the learning machine on the sofa.

  Leng Siyu grabbed the learning machine, threw it on the sofa, and said: "Two little monsters, you guys are better than the third-year students! Aren't you tired of studying?"

  Little Yuanyuan asked the bug, "Are you tired?"

  Xiao Chongchong replied: "I won’t be tired with Xiao Yuanyuan. Let me study for ten minutes and I’ll be tired."

  Siyu sent the bugs to 0301. When she went home again, Xiao Yuanyuan said excitedly: "Sister! Brother Fei paid me the bonus."

  Leng Siyu roared "soaking" and carried Xiao Yuanyuan into the bathroom, filled the bathtub with water, and then peeled off Xiao Yuanyuan and put it in the bathtub...

  Little Yuanyuan fluttered in the water...the water splashed the silk rain who was undressing.

After a while, the two naked American silvers were wrapped in a piece of silver foam. Leng Yuanyuan was soaked in the foam that only two eyes were exposed. With splashes on both legs, he shouted happily: "Sister, the bath is so comfortable!" "

   "Gluck, elder sister is not allowed to tickle me—"

   "Nonsense! I rub my back, OK?"

   "Sister, let me rub it for you."

"Um."

   "Uncomfortable?"

   "It's boring, you work hard!"

   "I'm still a baby!"

   "Let you hit the sandbag, you don't hit the sandbag!"

  “It’s impossible to hit a sandbag. It’s impossible to hit a sandbag in this lifetime!”

  In the living room, Siyu’s cell phone ringtone "The Wedding in a Dream" has rang N times, but it has never been heard by two people who take a bath.

  ……

  Xia Pengfei stood in the yard blowing a cold wind, wondering.

  The light is on in the living room, so I shouldn’t sleep. Why don’t you answer the phone?

  Xia always has the spirit of perseverance, and he will not give up until the milky white light in the living room goes out.

  At the 283rd call, he finally heard a sound like a natural sound, "Say—"

   "I want to learn history." Xia Pengfei actually wanted to say another sentence, but he realized that only this sentence was his master key to opening the door of Siyu's house.

   Immediately afterwards, the doorbell rang.

   "Wait a few minutes..." Si Yu yelled quickly.

  The visit of the beautiful boy caused a bare **** and only a bath towel in Room 0101 to get busy for a while:

   "Shorts! Sister!"

   "Bath towel, sister!"

   "Pyjamas, pajamas, Yuanyuan!"

   "Hair hair! Blow!"

  Said it was a few minutes, Xia Pengfei waited outside the door for at least half an hour when the sisters were busy to open the door.

When Siyu opened the door, Xia Pengfei's eyes lit up.

  Siyu wrapped in a nightgown is a **** look like a water lotus. The snowy skin and jade skin exposed to the air and the plump aura reflected from the whole body are as charming as they are.

   "Believe it or not, I'll goug your eyes out." Siyu said fiercely.
