Extraterrestrial parasite

Naturally, an adult cannot meet a little girl, so Chen Yang could only laugh it off. Of course, if possible, he would not mind spanking the little girl hard several times to make her disrespect his brother.

The birthday dinner was quickly finished. Xia Yuerou put down her bowls and chopsticks and said sideways, "Mom, I want to go to the pedestrian street with Xiaole and the others to play for a while, okay?"

"Pedestrian Street? No!"

Li Yingai shook her head: "There are too many people on the pedestrian street at night. What if something happens to you three girls?"

"It's a pedestrian street and not some other remote place. How could something happen?"

Xia Yuerou said unconvinced.

"There are many thieves in the pedestrian street at night, and they like to prey on young girls. So Xiaorou, listen to your mother and go there again during the day tomorrow." Xia Zhenghe also persuaded.

"I will pay attention to my wallet." Xia Yuerou defended.

"Are you paying attention? Is it useful if you pay attention? Others rely on this dirty work to make a living, can you pay attention all the time?" Li Yingai still disagreed.

"you……"

How could Xia Yuerou give up so easily? She turned her eyes and looked at Chen Yang, "Then let my brother accompany us. Is that okay?"

"This..." Li Yingai looked at Chen Yang, a little hesitant.

"This is not bad. Xiaoyang can play with Xiaorou and take care of them."

Xia Zhenghe nodded.

Chen Yang wanted to refuse. It was not a good thing to go shopping with three girls. However, looking at Xia Yuerou's pitiful eyes, he reluctantly nodded.

"That's okay, but Xiaoyang, you must keep an eye on your sisters and don't let anything happen to them."

Li Yingai warned.

"Oh yeah!"

Xia Yuerou and the other two girls clapped their hands and looked extremely happy.

Now that he had received permission, Xia Yuerou couldn't wait to pull the two girls out of the door. Chen Yang had to follow closely behind. If he hadn't reacted quickly, the three girls would have maliciously closed the elevator door.

Xia Yuerou acted as if no one else was around and ignored the existence of Chen Yang, her brother. She chatted with the two girls about school and magazine celebrities, laughing from time to time.

As soon as he left his uncle's house, Chen Yang no longer had to keep that fake smile, and his face suddenly returned to a calm expression.

In fact, even before encountering the parasite, he had very little contact with outsiders. He always maintained an expression of keeping away from strangers and was too lazy to talk to others. Now that he has been parasitized by extraterrestrial creatures, in addition to showing his true emotions in front of his right hand, his most common expression in front of others is probably "expressionless".

Seeing Xia Yuerou's willful look, Chen Yang suddenly said: "Xiaorou, are you already a high school student? How are your academic performance?"

Chen Yang suddenly spoke, startling the three of them, especially Xia Yuerou. She had a headache when she heard the word academic performance. She rolled her eyes and said, "What does it have to do with you?"

"I was thinking..."

Chen Yang's eyelids drooped slightly and his tone was calm: "Would you like to tell your uncle and let me make up for your classes? After all, high school studies are very important, but they are related to your future life."

Make up a lesson?

Xia Yuerou's expression changed, and she said nervously: "Don't mess around, I won't ask you to make up lessons for me."

"It's okay if you don't let me make up the lessons. I can suggest that your uncle find other experienced teachers to make up the lessons for you. After all, high school study is too important."

Chen Yang once again repeated the sentiment that studying in high school is too important.

"No one can make up lessons for me, and I don't want to make up lessons."

Xia Yuerou, a playful person, naturally hated things like making up classes, so she warned, "Let me tell you, don't mention this in front of my dad, otherwise I will never be done with you."

After saying that, she looked at Chen Yang with disdain: "What's more, with your ability, you still want to give me extra lessons? You're just an ordinary college student who graduated with a second degree."

"Ding……"

When the elevator reached the first floor, Xia Yuerou walked out first with her two companions.

Chen Yang didn't feel angry at Xia Yuerou's ridicule. He just wanted to stimulate Xia Yuerou.

However, a girl with Xia Yuerou's temperament would not forgive someone easily after being provoked. She walked in front and whispered something to her two companions. Suddenly a sneer appeared on her face. She deliberately slowed down. Wait for Chen Yang to come over quickly.

"You just said you wanted to give me extra lessons, but do you have the strength?"

Xia Yuerou's eyes rolled.

Chen Yang's mind was running so fast at this moment. As soon as Xia Yuerou said this, he understood what it meant.

"I am a college student after all."

Chen Yang's tone of voice didn't even change. He looked straight ahead, as if there was something in front of him.

"Well, since you are so confident, there must be no problem if I test you, right?"

Xia Yuerou was smiling so much that her dimples appeared.

Chen Yang was noncommittal, showing neither agreement nor disapproval.

Xia Yuerou couldn't wait. When Chen Yang agreed, she immediately asked the question: "It is known that the left and right foci of the ellipse x2/16+y2/4=1 are f1 and f2 respectively, and the point p is on the straight line l; x-√3y+ On 8+2√3=0, when ∠f1pf2 takes the maximum value, what is the value of the ratio |pf1|/|pf2|?"

Xia Yuerou spoke in one breath, speaking at an extremely fast speed. Most people can't even remember the questions, let alone answering the questions.

Chen Yang was silent. Under the illumination of the street lights in the community, the shadow formed by his nose and cheeks seemed to make Chen Yang look "downcast".

Xia Yuerou was elated and felt that she had gotten revenge on Chen Yang, but she was unwilling to give Chen Yang an excuse to admit defeat. "Did you understand the question clearly? If you didn't understand it clearly, I can tell you again."

"No."

"The answer is √3-1."

Chen Yang's face turned slightly to the side, and Xia Yuerou couldn't see his specific expression clearly, but it didn't matter, she could only feel the shock in her heart now.

This was impossible. She never expected that Chen Yang would just be silent for four or five seconds before speaking out the answer. Yes, this is indeed the correct answer. I was punished by the teacher and copied this question twenty times. Of course, I remember the correct answer clearly.

But because of this, she felt shocked. Xia Yuerou knew how fast she had just said the topic in one breath. Most people couldn't remember it at such a fast speed, so how could they talk about solving the problem?

Even if you can remember the question, can you solve this problem just by mental arithmetic?

She didn't know if her math teacher could solve the problem by just relying on mental arithmetic, but she was certain that her math teacher would never be able to solve the problem in just four or five seconds by just relying on mental arithmetic.

Looking at the whole of China, there are very few people who can do such a thing.

unless……

"You've seen the answer to this question before, right?"

Xia Yuerou thought that her doubts had been resolved. She laughed "haha" and said, "Don't think you can fool me."

Chen Yang raised his head and looked at the sky, ignoring Xia Yuerou's "misunderstanding" and asked, "Should we go there by taxi, bus or subway?"

"You're cheating. Knowing the question a long time ago doesn't count as winning."

Xia Yuerou ignored Chen Yang's question. She was more concerned about embarrassing Chen Yang than taking any transportation to get there.

"Xiao Le, Xuan Xuan, come here and ask a question to test this guy."

Xia Yuerou couldn't think of any difficult problems in her mind for a while, so she simply waved to her two companions with good academic performance.

Xia Yuerou had told them her plan before, so they naturally understood what Xia Yuerou meant.

"Xiaorou, it seems your cousin is very smart. Didn't you give him a hard time?"

It was Zhang Xiaole who spoke. With her short hair, she looked extremely youthful and lively.

"Hmph, this guy happens to have read the answer to this question beforehand. You two will give him a difficult question to test him."

Chen Yang felt a little impatient. He was not very happy to accompany the little girls shopping, but now he had to face the difficulties of three little girls, which made him feel even more uncomfortable.

"Okay, then brother, I won't be polite."

Zhang Xiaole saw that Chen Yang was Xia Yuerou's brother, so he also shouted.

"etc!"

Chen Yang suddenly stopped shouting, as if he thought of something, his face changed slightly.
