Most students weren't interested in Xu Zifan's materials. After all, even with his significant improvement, he only ranked first in Class 3, still lagging behind Classes 1 and 2, especially in physics, chemistry, and biology, where his scores were low and unlikely to be helpful to them. However, about half the students in Class 3 were tempted. They had personally witnessed Xu Zifan studying and taking notes every day and could sense the value of his materials. So, after observing for two days, more than thirty students bought his materials.
Some bought single-subject notes, others bought notes for several subjects. Xu Zifan charged 30 yuan for each note, and in the end, he made 5,000 yuan from his classmates! This time, Xu Zifan and Yan Yaru split the money 50/50, thanks to Yan Yaru's highlighting of key points and Xu Zifan's summarizing and organizing. Yan Yaru was truly amazed by his method of making money, and when she received the money, she looked at him incredulously a few times, "Why do you have so many unique ideas?"
Xu Zifan laughed and said, "It's innate, I guess." Actually, he had experienced too much. He had struggled all the way from the slums and seen everything. There are countless ways to make money, and this was just a piece of cake.
Yan Yaru's eyes showed a hint of admiration as she put the money away. Then, she frowned with some concern. "You really only sleep three hours a day, as you said? How can that be? Even if you want to study, you don't need to be in such a hurry. You're very smart and learn quickly. You'll definitely be able to learn all the knowledge before the college entrance exam. You don't need to work so hard."
Xu Zifan looked at her and said, "There's always a future ahead. Compared to other things, studying is the easiest thing to do, and it's not hard. Besides, I'm in great health. Look at me, I've been doing well lately. If I were tired, I definitely wouldn't keep going, so don't worry."
Yan Yaru looked at his complexion; it was indeed very good. At least half of the senior students would rest during breaks, closing their eyes to relax, because they were exhausted from studying. But Xu Zifan was always energetic, seemingly full of vitality. She'd heard he used to sleep in class; she wondered why he'd changed so much. Could it really be because of Ji Yuxin's betrayal?
For some reason, Yan Yaru felt a little awkward about this reason. Ji Yuxin had a terrible character and was always sarcastic and cynical whenever she saw her. If Xu Zifan had changed so much because of Ji Yuxin, it would be too much of a waste. Was he really that blind? However, Yan Yaru didn't ask. She flipped through her textbook and started her daily live stream with Xu Zifan.
They've already started teaching first-year high school courses, much to the dismay of a large group of middle school students who previously liked them. They're begging them to explain the middle school curriculum in more detail and not to cover high school material. Meanwhile, some high school students who discovered the live stream are happy, saying they've found a useful platform and no longer need to worry about not understanding the concepts. The fact that they only teach physics, chemistry, and biology, without covering Chinese, math, or English, is a source of great disappointment for many students.
Xu Zifan laughed when he saw their comments and said, "Don't worry, the young lady is mainly tutoring me. Once I've learned everything, we'll consider teaching other subjects. You'll get what you want in the future, just be patient."
Newcomers were commenting in the live chat that it would take forever to learn this, and they could all tell that Xu Zifan was relatively bad at physics, chemistry, and biology. But the veterans were laughing and replying that they didn't understand the world of academic geniuses. This young man finished the entire junior high school curriculum in just one month. So what if he was in high school? Watching their live streams is like witnessing miracles. It's so inspiring that it makes them want to study too. What if they also have the talent and can take off like him?
The live stream became increasingly lively, and their earnings also increased. After gradually gaining fame within the high school community, students from No. 1 High School finally recognized them.
[My God! Aren't these two popular figures from our school? Why are they doing a live stream together? What's their relationship?]
[I saw them walking together before; they seemed to be neighbors. But wasn't the former academic star incredibly wealthy? Did she go bankrupt?]
[This female academic genius is giving an amazing lecture! Don't you guys know her? She's the one who always gets first place in the city's joint entrance exam! The guy next to her is a prodigy who improved his score by 200 points in a month! Wow, he's already learning first-year high school material so fast, is he going to improve by another 200 points next time? Incredible!]
[A 200-point increase isn't that easy. He already scored over 580; another 200 points would be incredible, haha. But he's definitely a genius. He just really loves money. He sold study materials before, and now he's giving live-streamed lectures. Is his family short of cash?]
[What materials? Where can I buy study materials? I want to buy them!]
[Hey there, are you selling middle school study materials? I'd love to buy them! I really love your lessons, they're so much better than my private tutor's! Please leave your contact information if you're interested!]
Xu Zifan's heart stirred upon seeing the comments. He smiled slightly and said, "Want study materials? No problem. I'll let everyone know after I've reorganized them. If there are many requests, I'll consider it more carefully. Now, if you want to confirm your purchase of junior high school study materials, type '1'. Thank you. Also, my dear classmates, please don't leak our information. We just want to earn our tuition for next semester. After all, we're 18 now, it's time to grow up and experience earning money early. We also hope our live stream can help you. Please follow us if you like it, thank you."
As soon as Xu Zifan finished speaking, a string of "1"s appeared, and the number continued to increase, quite considerable. Their live stream was quite popular right now. After closing the live stream, Yan Yaru breathed a sigh of relief. She had been a little nervous when her classmate from No. 1 Middle School appeared. She wasn't very good at interacting with people on screen and didn't know what to say. Fortunately, Xu Zifan was there, never letting the conversation go cold, and perfectly glossing over her situation, leaving her no time to think about it.
Yan Yaru looked at Xu Zifan with a puzzled expression, "Is there anything you can't do?"
Xu Zifan placed the workbook directly in front of her. "I don't know how to do this chemistry problem. Miss genius, can you tutor me?"
Yan Yaru smiled and picked up her pen to explain the problem to him.
That evening, as soon as Yan Yaru left, Xu Zifan began organizing his junior high school notes. It wasn't the kind of dry, boring knowledge points; instead, he incorporated a lot of his own interpretations, meticulously creating a review document like a tender proposal. He didn't sleep until 2 AM. Actually, he was just as busy when he first started from scratch, drinking black coffee to stay awake when he was tired, wishing he could be several people in one. However, he was indeed very physically exhausted back then, often suffering from headaches, which only subsided after he achieved success and sought treatment from renowned doctors for a long time.
But now that he's traversing multiple worlds, his soul is growing stronger, and the bodies he travels to are nourished by his soul power, becoming healthier. This intense workload is quite easy for him; three hours of sleep a day is his absolute limit, and he doesn't feel uncomfortable at all.
Some students from No. 1 High School tried to study for as long as he did, but they could only last two or three days before giving up. They were so sleepy at night that they couldn't keep their eyes open, and they would doze off in class during the day. Their efficiency not only didn't improve, but actually decreased significantly, scaring everyone away so much that no one dared to try it anymore, making them think Xu Zifan was a genius. But the other method Xu Zifan mentioned was indeed effective, and some self-disciplined students began to use their spare time to memorize vocabulary and texts.
This method might have been known before, but generally no one tried it. Seeing Xu Zifan's success led them to try it, which unexpectedly yielded good results. The students were quite happy to see the success and developed a greater liking for Xu Zifan for sincerely sharing his experience with them.
Because teachers frequently used Xu Zifan as an example to motivate everyone, the students' enthusiasm for learning increased significantly. If someone who was a poor student could turn things around, why couldn't they? Everyone had a competitive spirit; no one wanted to lose to someone who had once been a poor student. The most miserable among them was Ji Yuxin, but she wasn't doing it willingly; she was forced into it by the Yan family.
Previously, the Yan couple had been rather cold towards her. After transferring her to the first class, they didn't pay much attention to her, hoping that she would experience the harsh realities of life and face some setbacks after entering the upper class, so she could understand that she had to work hard to adapt to her new status. Who knew that Ji Yuxin would spend all her time going out with Li Xudong, actually giving up on befriending other rich girls, and even getting second to last place in the exam, which was a complete slap in their face.
While they were furious, they also felt they couldn't let things continue. No matter how long they delayed, they had to reveal the truth about the switched babies. At the end, Ji Yuxin couldn't be too much worse off than Yan Yaru; at least on the surface, things had to look presentable. So they hired elite tutors to teach Ji Yuxin at home, taking up all her free time. She was driven to and from school, and they forbade her from going out with others. Ji Yuxin didn't dare anger them and could only obey. But she was used to having fun, and this restriction made her extremely uncomfortable. Why could Li Xudong and the others go out and play freely? Why couldn't she? How many rich kids were better at studying than her? It was just that Yan Yaru scored over 700 points, surpassing her. Why did her parents insist on comparing her to Yan Yaru?
No matter what she wanted to do, she had to accept the "training" of the Yan couple, and on the surface, she had to happily please them while inwardly suffering unbearable pain. She didn't even have the desire to cause trouble for others. This time, the Yan couple learned about her past, and their first impression was disgust. They felt that her flattery and obedience were all hypocritical, so they naturally had no intention of making amends. Instead, they were full of criticism, treating her like a stubborn stone to be polished, hoping for a miracle to sculpt a piece of jade.
The Yan family was extremely dissatisfied with Ji Yuxin, but the Ji family and Yan Yaru were getting along better and better. Yan Yaru intentionally wanted to learn more tricks from Xu Zifan, including filial piety towards her parents. She learned Xu Zifan's tricks for coaxing people, and although she didn't do them very well, she became much closer to the Ji couple, and the family of three was becoming more and more harmonious. Therefore, the Ji couple chose a suitable time to bring up the matter of changing Yan Yaru's surname, and changed her household registration, ID card, and personal file, because it would be difficult to change her name after the college entrance examination.
This time, Yan Yaru agreed without hesitation, so the Yan family had no choice but to change their household registration as well. From then on, Yan Yaru changed her name to Ji Yaru, and Ji Yuxin changed her name to Yan Yuxin. Both changed their names at the same time; one went from wealth to ordinariness, and the other from ordinariness to wealth. The classmates finally learned about the mix-up at birth. While lamenting the unpredictability of life, they subconsciously sympathized with Ji Yaru. After all, Yan Yuxin had become somewhat arrogant after gaining wealth, while Ji Yaru had never changed, regardless of wealth or ordinariness. The classmates couldn't help but secretly compare the two, and Ji Yaru was the clear winner.
