Liu Chen looked at the boy he had never met and smiled and said, "Do you want to know how I entered Dongqiba?"

He nodded heavily, "I want to know."

"This is a secret, and you can't tell others casually, but if you give me five hundred dollars, I can consider telling you."

The boy's face changed, his heart was furious, and his chest was fluttering. Isn't this a robbery? Hard Bangbang said: "Student, don't make such jokes."

"I didn't joke with you. If you want to know, just take the money."

The boy doesn't know what to say.

Liu Chen didn't talk to him, but raised his legs and walked towards the library.

BBS's previous post quickly became popular and went to the top ten home page: the first man to enter East Eighteen!

On September 1, 2003, the new library of Jianghai University opened on the first day. Today is also the day of reporting. There are many students and parents in the school. After three years of depressed high school, the young freshmen finally entered the ivory tower full of fantasy. They started their college life in their youth and longing.

Jianghai University’s new library is definitely the best library in the country, and it should be no less. Liu Chen had visited many famous universities in his previous life and had never seen any better ones.

It was so good at school. Liu Chen looked around but didn't see Zhuo Ling. He felt a little disappointed. It seemed that she had left, found a book and read it freely. When she was annoyed, she took out a book and wrote two papers in the memory. One could meet the standards of a core journal, and the other was almost the level of ei.

When I have nothing to do, I always have to write a few papers to play with. After all, I still need to do academic work in school.

After returning from the toilet, I saw two classmates standing next to his seat, fiercely arguing about something. The location he chose was next to the aisle and approaching the stairs. It just so happened that the entrance to the library was overlooking the students, and the students could talk and discuss here. It was not possible in the library.

A boy and a girl look like freshmen. A high school child has just entered college and his characteristics are still very obvious. The boy has very short hair and meticulously wore a half-sleeved shirt with long trousers underneath, and his shirt is stuffed into his pants. He is very thin and has a pointed head.

The girl was wearing a long skirt, but her skirt was wrapped very tightly, dark, slightly fat, and her forehead was a little protruding. She looked like a high school girl, and her head could only be tied to the length behind her ears, and she had a set of headbands.

Liu Chen walked back to his seat. The two children moved outside and continued to argue. When they heard what they were discussing, they were indeed freshmen in their first year.

Being able to enter Jianghai University is the best in all high schools. You come to the library to read books before school starts. Being a top student must be diligent and hardworking. Children who have just graduated from high school love to study.

The two argued a few more times, and the boy said excitedly: "This sequence (1+1/4)(1+1/9)(1+1/16)...(1+1/n*n) is multiplying infinite terms, each term is greater than 1, so it will definitely not be convergent!"

As he said that, he drew a formula on the paper, and another girl said, "Not necessarily. I feel able to restrain myself!" Sometimes girls just look at the feeling.

"Then tell me how it converges? Have you never heard of it? Even if the thin paper is folded dozens of times in a row, it can reach an unimaginable height! There is no boundary in this sequence at all! It is impossible to converge!"

The boy's stern words were very intense. He did not say anything about being sympathetic when arguing. He could not say anything about the girl in such a question.

The discussion was fierce and the voice was loud. It seemed that if you didn't help them solve this problem, you wouldn't be quiet. Liu Chen took a casual look and realized it in his heart, and said lightly: "This sequence is indeed convergent!"

The boy said dissatisfied: "How can it be converged? Can the unbounded sequence also converge?"

Liu Chen asked back: "How do you know that this sequence cannot converge?"

"The first term of this sequence is 1.25, and the tenth term is 1.01, which must be infinite, the supreme realm, and will not converge!"

Liu Chen was not in a hurry and smiled and said, "I have learned a formula of square deviation in junior high school, do you still remember?"

"Of course I know this formula. We are now discussing the limits and convergence questions in [Advanced Mathematics], which is not a pediatrician in junior high school." The boy's tone was quite proud. He was the first in the city in the middle school entrance examination that year.

Liu Chen didn't say anything, and directly wrote the square difference form of the sequence just now on the paper, looking at the two, "Can you understand it here?"

The two of them frowned and looked at it, feeling that such a change had indeed had a great effect, but they still couldn't figure out the key.

After waiting for a while, Liu Chen saw that the two of them had not seen through it, so he had to write another change on the paper. They are both academic masters and have a very good foundation. As a result, he suddenly realized it.

Liu Chen wrote another difficult sequence and said: "In fact, the sequence in this question is not complicated enough. It can be obtained by directly simplifying the results. If it is a more difficult sequence, the value of this roundabout method can be reflected!"

The boy looked at Liu Chen in surprise, his face felt a little hot. He did lose, but he was convinced. The man in front of him must have a deep attainment in [Advanced Mathematics], not only could he explain it clearly, but he could also learn from it.

The girl showed joy on her face and said, "Wow, you must be a senior in the mathematics department, right? You are so awesome. I have heard from my cousin that there are great people everywhere in Jianghai University, and it turns out that's true."

"I'm from the Electrical Academy." Liu Chen didn't want to say that he was a freshman, so that the two of them would make a fuss again. "Ha, it was a bit confusing to learn [Advanced Mathematics] at the beginning. The teacher talked very quickly in class, so it was right to preview in advance."

The girl stood up seriously, reached out her hand, and said, "Hello, senior, it's such a coincidence. We are also freshmen of the Electrical Academy. My name is Tang Xiao. This is my high school classmate Wang Cong. We are both Qidong Middle School in Suzhou Province, and all high schools are experimental classes. We are still classmates now."

It turns out that these two people came from Qidong High School in Suzhou Province. Qidong High School is almost known to every student that they are very awesome in competitions and further studies. The secret volumes leaked from the school are circulating across the country.

Liu Chen reached out and shook Tang Xiao and let go. It was unnatural for Wang Cong to stand there. Tang Xiao touched him. The young man mustered up the courage to look up at Liu Chen, and also reached out and said, "Senior, I'm sorry, my tone just now was a little anxious, don't mind."

Tang Xiao also said to the point: "This is what he is. Haven't you ever heard of a good man not fighting with a woman? Every time I argue with me, I feel like I want to eat people. I'm so stingy..."
