Chapter 227 Determining the direction
In the car, Han Yi noticed that Li Wenxi was a little absent-minded, and turned to ask: "What's wrong? You seem to be worried."
Li Wenxi came back to his senses and explained: "No, I just encountered some doubts in the paper I read recently, and I can't figure it out for a while." He briefly described the difficulties he encountered in the cryptography paper, "I didn't find this piece of information in the library of Tsinghua University, and I feel that my thinking is stuck here."
Han Yi frowned slightly after listening, and after thinking for a moment, he said: "The Chinese Academy of Sciences data room in Zhongguancun has many professional books, maybe you can find the answers you need. Otherwise, let's go over and take a look now?"
Li Wenxi's eyes lit up, and he asked in surprise: "Chinese Academy of Sciences? Can we go in and borrow information?"
"I'll just get two borrowing cards." Han Yi said with a smile, "Let's go now."
Han Yi did what he said and turned the car around at the intersection ahead.
Li Wenxi hurriedly said, "Why don't we go eat first?" She was afraid that Han Yi would be hungry.
Han Yi smiled and said, "Borrow the books before eating, otherwise I'm afraid you won't be able to enjoy the food. It doesn't matter if you wait for a while."
Li Wenxi didn't insist.
In the Chinese Academy of Sciences' data room in Zhongguancun, Li Wenxi was looking through rows of bookshelves, while Han Yi would occasionally take out a book and ask Li Wenxi if it was what she needed. Although he was not a student majoring in mathematics, he was also a top student. Li Wenxi described the information she was looking for in a little detail, and Han Yi understood it. He helped find all the information he thought was relevant and finally let Li Wenxi read it.
Because there was not much information on cryptography, and with Han Yi's help, Li Wenxi found the book she wanted in less than an hour.
The moment she found it, Li Wenxi almost jumped up. She didn't expect that there was such a book that could answer her doubts. She kept thanking Han Yi, "Han Yi, thank you for helping me solve a big problem."
Han Yi smiled, "You can have a good meal next."
"Whatever you want to eat, eat whatever you want. I'll treat you."
Han Yi took Li Wenxi to a private restaurant. The environment of the restaurant was quiet and elegant. After entering the door, the wooden tables and chairs and the simple and elegant calligraphy and paintings on the wall created a calm atmosphere. The air was filled with a faint sandalwood scent, and the whole space seemed to be isolated from the outside world, making people relax immediately.
"It's nice here, isn't it? The dishes are also very exquisite." Han Yi walked in front and said lightly.
Li Wenxi nodded, looked around, and suddenly felt much more relaxed.
The dishes were quickly served, and several signature dishes such as braised pork, steamed sea bass, and stir-fried vegetables were placed in front of him, with a fragrant aroma. Han Yi picked up a piece of braised pork and handed it to Li Wenxi's bowl: "Try this braised pork, it's quite famous."
Li Wenxi took a bite, the meat was tender, fat but not greasy, and instantly felt that her taste buds were satisfied, and smiled: "It's really delicious, I like braised pork very much."
"That's a coincidence, I also like to eat braised pork." Han Yi replied.
The waiter at the side brought pork chop soup, and Han Yi scooped another bowl and handed it to Li Wenxi, "Drink some soup to replenish your brain. You will have time to solve your problem in the evening."
Li Wenxi took the bowl with a smile, "Thank you."
"Are you ready to specialize in cryptography?" Han Yi asked.
"Not sure yet, but I am becoming more and more interested in cryptography." Li Wenxi said softly, with a trace
of seriousness in his eyes. "I think you will do well." Han Yi said, there was no unnecessary exaggeration in his tone, only a firm trust.
Li Wenxi looked up at him in surprise, "You believe me so much?"
Han Yi smiled faintly, his tone calm but firm: "From the day I met you, I knew you would do what you wanted to do."
"Thank you." Li Wenxi felt warm in her heart and lowered her head to drink a sip of soup.
"Actually, you make me feel the same way." She added softly.
Han Yi paused and looked at her seriously: "Yes, what I want to do will definitely succeed."
Li Wenxi was stunned for a moment, realizing that Han Yi's words seemed to be hinting at something, and hurriedly lowered her head to drink the soup.
Fortunately, Han Yi did not continue to talk, and turned to talk about other things.
After the meal, Li Wenxi still failed to pay, because Han Yi was one of the shareholders of this restaurant, and the waiter did not accept her money.
Han Yi smiled and said, "You can treat me next time."
Li Wenxi was helpless: "Next time, next time, how many next times will there be."
Han Yi smiled and said, "Then I will never be able to count them all in this lifetime."
After returning to school, Li Wenxi gradually devoted her energy to the study of cryptography. Under the guidance of Professor Chen, Li Wenxi had a deep understanding of the distribution of prime numbers under certain conditions, and asked her to write a detailed paper on this.
After reading it, Professor Chen was impressed by her potential and decided to recommend her to Professor Wang, a top expert in the field of cryptography.
Professor Wang had cracked several extremely complex cryptographic systems in the world and was recognized as an authority in the cryptography community. Li Wenxi did not expect that she would be lucky enough to get such an opportunity, and she cherished the opportunity to learn from Professor Wang even more.
In the following years of college, with in-depth study and research, she felt more and more the mysterious connection between prime numbers and cryptography. Her research direction became clearer and she decided to follow Professor Wang to study for a master's and doctoral degree, specializing in cryptography.
Time flies and it's time to graduate from college. The other three people in Li Wenxi's dormitory all choose to study abroad.
Hao Sanmei is also preparing to study simultaneous interpretation abroad.
Zhang Shulan, like Li Wenxi, continues to study abroad. She has a clear goal. She wants to stay in school and become a Chinese teacher in the future, while writing novels part-time.
In the four years of college, Zhang Shulan wrote several novels, and all of them were best-sellers. It can be said that she is not short of money at all. She lives a very carefree life. However, Zheng Shunli was assigned to the Ministry of Commerce in Shanghai,
and the two had to live in different places. Gao Hui was assigned to work in a state-owned enterprise in Beijing. However, since the dispute with Hao Sanmei, she rarely contacted Zhang Shulan and Li Wenxi.
Graduation is approaching, and there are many people packing their luggage on campus, and some are setting up stalls to sell second-hand items. These people are basically leaving Beijing. It is inconvenient to take things away, but it is a pity to throw them away, so they set up stalls to sell things on the campus road. The atmosphere of parting is everywhere.
After Li Wenxi's dormitory dinner, the other three have already left school, leaving only Li Wenxi. Looking at the empty dormitory, Li Wenxi felt a little lost, but she didn't have much time to feel sad.
During this time, Professor Wang received an important task from the Ministry of National Defense - to design a new information security system. Although Li Wenxi was only an undergraduate, Professor Wang treated her as a graduate student due to her outstanding performance in prime number research and directly involved her in the project.
