Only a week after the midterm exams, Zheng Li regretted his decision. Classmates kept coming to him, and after discovering that he could solve all their difficult problems, word spread and more and more people came to him.

Some senior students who were preparing for graduate school entrance exams even asked him questions about mathematical analysis and higher algebra.

The core courses for postgraduate entrance exams in mathematics are mathematical analysis and linear algebra, excluding statistics.

The better the school, the fewer poor people there are. In subjects like mathematics, where economic benefits are not directly visible, there are even fewer students from impoverished families.

Therefore, students in the Department of Mathematics are not short of money, and the tuition of only one hundred yuan for half an hour is too cheap for them.

On his best day, he earned a thousand, but he wasted all his time on it. Zheng Li felt that the monk's life was being wasted.

He can multitask, but frequent communication with people still takes up a lot of energy.

More importantly, the monk spends a lot of time alone researching topics that interest him, which, to put it bluntly, makes him a bit socially anxious.

Zheng Li felt uncomfortable having to meet several different carbon-based intelligent life forms every day.

Just when he was troubled, Li Miaomiao came to his door. Zheng Li was puzzled that Li Miaomiao hadn't bothered him during this time.

Li Miaomiao sent him a message on WeChat: "Is business booming lately?"

“I heard from my classmates in the math department that there’s even a line of people in the study room looking for you every day.”

Zheng Li: "?"

"Speak quickly if you need anything."

Li Miaomiao: "I have a good idea for you. Recently, some senior students have come to you for help, and you answered all of them correctly. So I contacted the senior counselor in your math department for you."

"Have him announce it in the group chat for you. We can easily set up a tutoring class specifically for math majors preparing for the postgraduate entrance exam next week."

"If the timing is right, we can start next week. We'll find a classroom in Teaching Building 5 every weekend afternoon."

Zheng Li: "How much does it cost?"

Li Miaomiao: "It's mid-November now, and there's about a month and a half left before the postgraduate entrance exam. We can have four weeks of classes, two days a week, on weekends."

"It's about 32 hours in total. The price for a large class can't be the same as one-on-one."

"So I'm thinking of setting it at 1,500 yuan, which is about right for a month's living expenses."

Zheng Li felt the price was too high, and he asked, "How many people can you find?"

Li Miaomiao: "About a quarter of the students in the School of Mathematical Sciences take the postgraduate entrance exam every year. I also need to mobilize resources outside the school to help you contact Jiangcheng University of Science and Technology and Jiangcheng Normal University. Let's gather at least ten students."

"Otherwise, how can I demonstrate my worth as an old lady!"

Zheng Li estimated that this method would earn him about five times more than his one-on-one sessions: "Okay."

Li Miaomiao added, "Don't forget we're 91 points."

Zheng Li revealed his true intentions: "We can even split it 80/20, but there's something I need your help with."

Li Miaomiao paced back and forth in her dormitory, filled with curiosity. Her recent impression of Zheng Li was that he was a person without desires and focused solely on academics.

Although she earned some money by lecturing her classmates, she didn't notice that Zheng Li spent his money anywhere. He would always go to practice in the morning, go back after lunch, and sit there from the afternoon until the evening. His clothes didn't get any better because of the money he earned.

Li Miaomiao considered herself a beauty, but every time Zheng Li talked to her, he looked directly at her naturally, without any desire or evasion in his eyes.

If it weren't for the fact that many male students in the School of Economics and Management expressed their affection for her, Li Miaomiao would have wondered if her charm had rapidly declined.

"It must be something very difficult to get someone as greedy as you to give in. Tell me first and I'll see if I can help you."

Zheng Li said frankly, "I know your parents work at Jiangcheng University. I want to do an internship in the biomedical polymer materials laboratory. Do you have any ideas on how to do that?"

After a moment's thought, Li Miaomiao knew which laboratory Zheng Li was referring to. The history of the Biomedical Polymer Materials Laboratory dates back to the 1980s, and it has produced two academicians.

She asked, puzzled, "What are you doing in the biology lab if you're a math student?"

Zheng Li said directly, "I want to develop in the field of biocomputing in the future, so I want to work on some biology projects."

As if realizing something, Li Miaomiao raised her voice by a decibel: "How do you know my parents work at Jiangcheng University?"

Zheng Li explained, "After you came to the study room to ask me a question last time, I overheard you making a phone call outside. Given how familiar you were with Professor Liu Gui and the fact that you're from Jiangcheng, your parents are most likely staff members at Jiangcheng University."

Hearing this was part of it; the other part was that Zheng Li directly hacked into the database where Jiangcheng University stored student information and found the data.

Without a dual-cloud physical architecture for both internal and external networks, and only having a database server for basic web protection and vulnerability detection, Zheng Li sees it as no different from a piece of paper.

He found from the database that Li Miaomiao's father was a professor who graduated from the School of Biology at Jiangcheng University with a bachelor's, master's, and doctoral degree.

Li Miaomiao felt helpless about her carelessness at the time, but she couldn't show her fear: "How could you just pry into my privacy!"

“I didn’t hear anything,” Zheng Li replied.

Li Miaomiao didn't dwell on this too much, and she didn't want the other person to know her parents' identities, so she asked, "You don't need to go to the biomedical polymer materials laboratory right away. There are many laboratories in the School of Biology."

"There are so many directions in biological experiments: physical chemistry, organic chemistry, inorganic chemistry, electrical engineering, chemical engineering, biochemistry, microbiology, and so on. I suggest you start with basic experiments."

"With your high school biology level, even if you plan to do computational biology that analyzes protein structures, you'll have to start from the basics."

Zheng Li: "I'm more interested in biomedical polymers. You don't need to let me go directly in. Just help me get an interview opportunity, and I'll pass the interview myself."

"Wait a minute, let me ask for you."

Li Miaomiao didn't actually want to ask her father for help. She knew that if she did, Zheng Li would definitely be thoroughly investigated by her father.

The father was always wary of any male friends who appeared around his daughter, especially since Li Miaomiao was only a freshman in college.

Li Miaomiao made a phone call to her father, Li Xulin: "Dad, a friend of mine wants to work in your medical polymer laboratory. Can you help me arrange it?"

Li Xulin is a professor in the School of Biology. At just under fifty, he's nearing the end of his prime for scientific research. He received a call from his youngest daughter in his office, and asked with a puzzled expression:

Which friend?

Li Miaomiao knew that Zheng Li had gone to the biology lab for an internship, and she knew she couldn't hide it from her dad: "He's a friend I just met recently."

Li Xulin asked, "Are you from your department? Tell me about your background."

"She's from the School of Mathematics. I met her at an event organized by the Student Union last time. She's a super academic achiever! She's already finished all the basic math courses for freshmen and sophomores, and she got full marks on all the midterm exams."

“He said he was very interested in biology and wanted to pursue a career in computational biology, so he wanted to work in your medical polymer lab now,” Li Miaomiao answered honestly.
