When Wang Yi arrived in Rivertown, he got out of the taxi and went to a public toilet nearby.
Wang Yi took off the human skin mask on his face and threw it into the sewer of the toilet before leaving the toilet. He then hailed a taxi by the roadside and headed back to his house.
The taxi stopped at the entrance of his neighborhood. Wang Yi paid the fare, got out of the car, and entered the neighborhood. Then, he walked home.
He came downstairs. Wang Yi went upstairs and knocked on the door.
"Who is it?" An unusually familiar seductive voice came from inside.
"Me!" Wang Yi shouted.
"Wait a minute." There was a sound of light footsteps coming from inside the door, followed by the sound of the door opening.
"You're back? Did you have fun at the class reunion today?”Yun Mengyi opened the door and saw Wang Yi. She immediately asked Wang Yi with concern.
"It's alright." Wang Yi said.
"That's good." Yun Mengyi said and turned around to walk inside.
As she walked, she said,"Yuyan has something to look for you."”
"What is it?" Wang Yi asked.
"It's a few math questions. They're very difficult. I don't know them either. She could only wait for you to come back and ask you.”Yun Mengyi said.
"Oh." Wang Yi replied and walked towards Wang Yuyan's door.
At this moment, Yun Mengyi suddenly seemed to notice something as she said to Wang Yi," Wang Yi, why do you smell like a woman's perfume?”
Hearing Yun Mengyi's words, Wang Yi's heart subconsciously skipped a beat. He then said without changing his expression," At the gathering today, a girl bumped into me. It should have been left behind at that time."”
"That girl is quite rich. She actually uses Chanel perfume. And it was a Chanel Miss Coco perfume that was worth more than 1,000 yuan.”Yun Mengyi sniffed carefully and sighed.
As a woman, she was naturally very familiar with perfumes, especially famous perfumes like Chanel and Dior.
She could tell what kind of perfume Wang Yi was wearing with just a sniff.
Wang Yi complained in his heart. Wang Xiaoya was a big star after all. It was normal for her to use perfume that cost more than 1,000 yuan.
He did not say anything to Yun Mengyi and went to Wang Yuyan's room, then knocked on the door.
Soon, the sound of a door opening could be heard.
"Brother, you're finally back!" When Wang Yuyan saw Wang Yi, she could not help but exclaim in joy.
Today was Saturday, and the school had given out a lot of test papers.
She chose to do the math test first, but she did not expect to encounter four or five difficult questions as soon as she did it.
She could not solve it, so she asked Yun Mengyi for help. Who knew that Yun Mengyi knew nothing about it.
Wang Yuyan sighed. Yun Mengyi had gone to university for nothing. She didn't even know how to solve high school math problems.
She had no choice but to wait for Wang Yi to come back and teach her.
After all, Wang Yi was also a university student. He might have already learned it.
She didn't have much hope. After all, Wang Yi had bought his grades to get into university in this world, but it was better than nothing.
"What question is it?" Wang Yi asked.
To be honest, he wasn't confident. His mathematics was not good. In the past, he had barely passed the cut-off point for university. As for Wang Yi in this world, he was even worse. He had actually bought his grades to attend university.
However, Wang Yuyan was his younger sister after all. His heart ached for his younger sister, so he wanted to do his best to help this younger sister and see if he could solve her problem.
"Come with me. These are the questions.”Wang Yuyan said to Wang Yi and walked to the table she usually used to do her homework. She pointed at the five questions on one of the papers on the table.
These five questions were the last few questions on this paper. They were very difficult and she did not know how to answer any of them.
Wang Yi nodded and picked up the test paper on Wang Yuyan's desk. Then, he read it carefully.
He looked at the first question and felt awkward. He didn't know how to answer it either.
When she looked at the second question, she felt awkward again. She still didn't know how to answer it.
Then, the third question, the fourth question, and the fifth question were all awkward. He didn't know any of them.
He couldn't help but curse in his heart."F * ck, which f * cking teacher set this test paper? Do you even know how to set a test paper?”
However, he still had his dignity, so he couldn't reveal it. He immediately communicated with the system without batting an eyelid.
"System, is there any way to help me solve these problems? I don't want to lose face in front of my sister.”
"Host, there is. The system has a high school math proficiency book here. As long as the host learns the content of this math proficiency book, he will be able to easily solve these questions.”the system said.
"Then hurry up, but don't appear in my hands this time.”Wang Yi said.
With his sister present, he couldn't let the system pass something like Mathematics Proficiency to him and let his sister see it.
"Host, this High School Mathematics Proficiency requires 100 popularity points to exchange. Host, are you sure you want to exchange?”The system asked again.
"Nonsense!" Wang Yi said," For the sake of my sister's future, I'm willing to spend 100,000 popularity points.”
"Alright." The system responded and deducted 100 popularity points. Then, it transferred all the content of the high school mathematics proficiency into Wang Yi's mind.
After Wang Yi digested the information, he instantly grasped all the content of high school mathematics.
To put it bluntly, the current him could easily be a math teacher in the third year of high school.
He looked at the questions on the test paper in his hand again and immediately felt that each question was easier than the last. He looked at it from the back to the front.
Not to mention that it was easy, even if he was asked to answer it, he could use several different methods to answer it.
"Brother, do you know how to solve these questions? If not, I'll leave it here for now. I'll go to school to ask my classmates on Monday.”Wang Yuyan asked Wang Yi when she saw that Wang Yi had been holding the test paper without saying a word.
"Yes, of course." Wang Yi replied and immediately found a chair to sit down. Then, he began to talk to Wang Yuyan.
Wang Yuyan listened to Wang Yi's explanation and suddenly felt enlightened. She did not expect this question to be so easy.
Not only that, but she could also use a few different methods to answer each question.
One question, two questions, three questions, four questions, five questions. Soon, he finished all of them. Wang Yi provided at least two or three solutions to each question.
In her eyes, these questions were as difficult as ascending to the heavens. However, in Wang Yi's hands, it was as easy as turning a palm over. It was like playing house for a child.
"Brother, you're amazing. I admire you to death. How did you do it?”Wang Yuyan looked at Wang Yi with countless stars of admiration in her eyes.
"It's very simple." Wang Yi said," Brother didn't spend four years in university for nothing. These questions are not difficult for Brother. In the future, no matter what math problems you have, come to me and I'll help you solve them.”
"Brother, my idol. In the future, I won't just look for you for math questions. Language, English, Physics, Chemistry, Biology, and so on. I'm looking for you. I'll leave the college entrance examination to you.”Wang Yuyan looked at Wang Yi, her emotions surging.
Hearing this, Wang Yi was speechless. Did his sister think that he was an all-rounded genius?
However, being worshipped by his sister made him feel very comfortable.
