Su Yichen didn't know that he and Lin Dong would actually pass by, but when Lin Dong told the story behind the photo to everyone in the showroom, he had already come to another part of the campus, stopping in front of a new building with a very modern atmosphere.

This was once the site of the old Red Building of Polytechnic University, which was built in the 50s of the last century, when it was a place for Soviet experts who came to aid China. Later, after Sino-Soviet relations deteriorated and all Soviet experts were withdrawn, this old red building became the school's dormitory building, and Professor Luo Shaohua lived here.

But now, the old Red Mansion in my memory is long gone, and there are no traces of my former familiarity around, and everything has become so strange. But in the depths of Su Yichen's memory, the small red building overgrown with green creepers seemed to be right in front of him, and on the first floor to the east, behind the window where the lights were always on late at night, was the home of the teacher and Luo Yan.

Standing in front of the old Red Mansion for a long time, Su Yichen didn't cry as before, but there was still infinite sadness in his heart, as well as deep reluctance and regret. The years have changed cruelly, and the 30 years have even made him feel that the 100 years he has spent with Ike have been even longer.

Leaving the old site of the old Red Mansion, Su Yichen went to see the library again, the old building of the library has also changed greatly from his memory, the new library is so magnificent, but it looks so strange, shaking his head and sighing lightly, Su Yichen is no longer interested in continuing to look for familiar things in the depths of his memory, turning around and leaving, walking towards the agreed place.

When he came to the agreed place, Li Xiao was already waiting, and when he saw Su Yichen, he hurriedly waved his hand to greet him.

"I'm sorry I'm late." Su Yichen said apologetically, he forgot the time for this visit, and he didn't know how long Li Xiao had been waiting for him.

"It's okay, I just arrived, and I was worried that you wouldn't be able to find the land." Li Xiao waved his hand very casually, and then sued him without waiting for Su Yichen to ask, he had already inquired about Luo Yan's situation.

As soon as he heard the news of Luo Yan, Su Yichen's mood instantly became a little excited, and he hurriedly asked about the result.

"Don't worry, sit down and talk slowly." Beckoning Su Yichen to sit down, Li Xiao told Su Yichen the news of his inquiry, he first went to the Department of Mathematics to ask a few professors, but several professors didn't know who Luo Yan was, and they had never heard of her name. Just as Li Xiao was about to go to the Academic Affairs Office to inquire again, a retired old faculty member happened to come to the office, and this old faculty member overheard Li Xiao mention that Luo Yan's name was a little different, and asked Li Xiao strangely how he knew about Luo Yan.

After listening to Li Xiao's explanation, the old faculty member told him that there was indeed a young associate professor named Luo Yan in the Department of Mathematics of the University of Science and Technology, and she was also the only daughter of Professor Luo Shaohua, the old dean of the School of Science. However, Professor Luo Yan left the school shortly after Professor Luo Shaohua's death, and I heard that she seemed to have gone abroad later, because 26 years have passed, plus several major changes in the school later, after a long time, almost no one in the school remembers Professor Luo Yan's affairs back then.

"She's out of the country?" The disappointment that could not be concealed appeared on Su Yichen's face, he never expected this result. But when you think about it, it's not impossible.

Luo Yan once studied at Princeton University, one of the Ivy League universities in the United States, and a few years after learning that she was missing, her father Professor Luo Shaohua died suddenly, which made Luo Yan feel a huge blow in her heart, for her, this is no longer a place worth remembering, but a sad place, the two closest relatives have left one after another, making her heart all hopeful, with Su Yichen's understanding of Luo Yan's character, she is likely to make the choice to leave school, and going abroad may be the final decision she makes.

So, where will Luo Yan go? Is it the United States? Or Hong Kong? Or is it somewhere else? Su Yichen thought hard, because these are possible, the reason is very simple, Luo Yan once studied in the United States, but he also knew that Luo Yan had an uncle who lived in Hong Kong, and there was also a distant aunt who seemed to be in any country in Europe, which means that she could go to these places, but the world is so big, it is not easy to find a person who has long lost contact for many years in the vast sea of people.

For a while, Su Yichen didn't know what he should do next, he had fantasized about the scene when he and Luo Yan reunited again, the original girl may have become goosebumps now, and even old, but Su Yichen's feelings for her in his heart will never change in any way, he just wants to find her and find his lover, because this is the person he cares about and loves in his life!

But the reality gave him such a cruel blow, first the news of his teacher's death, and then Luo Yan's whereabouts unknown, which made Su Yichen's heart empty and uncomfortable.

"Mr. Su......." Looking at Su Yichen's painful expression, Li Xiao didn't know how to comfort him, and he was also curious, although Su Yichen explained to him the reason for inquiring about Professor Luo Shaohua and Luo Yan, but he didn't know how to say it, judging from his feelings, the young man in front of him seemed to have a very unusual relationship with Professor Luo's family. But since Su Yichen didn't mention it, and Li Xiao was not convenient to ask, emotionally speaking, he was very willing to help Su Yichen.

Suddenly, a thought flashed through his mind, and Li Xiao hurriedly said to Su Yichen: "Actually, it is not impossible to find the whereabouts of Professor Luo Yan...... ”

"What! You say you have a way to find Luo Yan? Su Yichen's body shook suddenly, and he hurriedly grabbed Li Xiao's hand and asked urgently.

"Don't excite Mr. Su, I just said it's possible, oops, my hand is ......."

"I'm sorry, I'm really sorry ......." Su Yichen's strength was so great that he almost broke Li Xiao's wrist, he hurriedly let go and apologized repeatedly, but he still couldn't wait to ask what the solution was.

"Actually, the solution is very simple, try to search on the Internet." Rubbing his numb wrist, Li Xiao didn't blame Su Yichen for his recklessness, and said the answer.

"...... web search?" Su Yichen repeated these four words thoughtfully.

Li Xiao nodded, afraid that Su Yichen would not understand the meaning of Internet search, so he roughly explained to Su Yichen the purpose of the computer network, and then took the initiative to invite Su Yichen to his dormitory to use the computer to search and query.

For the meaning of computer network, Su Yichen is actually no stranger, you must know that he was an expert in this area, as early as the 70s, foreign scholars put forward the idea of computing network, in the early 80s, the local area network began to be used in the national computer center, 30 years later, with the development of modern science and technology, the use of today's computing network must be far beyond the level of the year, but as for what kind of development, Su Yichen has not been formally contacted after his return.

With curiosity, Su Yichen followed Li Xiao to the graduate student dormitory, Li Xiao lives in a good place, of course, this has something to do with his family background, you must know that ordinary graduate students can't afford to live in a single-family dormitory. opened the door, invited Su Yichen into the house, and walked into the dormitory only to find that this was a set of two bedrooms and one living room, the living room was not large, only about ten square meters, and a sofa and a set of dining tables and chairs were placed, which seemed very simple. One of the two rooms is Li Xiao's bedroom, and the other is set up by him as a study and studio, the computer is placed on the writing desk in the study, and Li Xiao opens the computer casually when he enters the study, the screen lights up, and soon an operating system called windows8 starts to start, and it doesn't take long for the computer desktop to jump out of the screen, showing that the startup is successful.

Looking at the computer in front of him, Su Yichen felt a little emotional, although he was the first time to contact the computer of this era, but when the computer started the retrieval, the few lines of English that popped up displayed the number jù, he keenly found that the configuration of this small computer is not simple, but the clock frequency is as high as 2GHz, that is to say, this computer can perform 2.2G operations per second, which is simply incredible back then.

What's more, in addition to the ultra-high clock frequency, its other series of parameters also surprised Su Yichen, but now is not the time to study the computer mechanism, sat down on the chair next to Li Xiao, watched Li Xiao take the mouse and skillfully click on the icon of the previewer, and then a network page popped up on the computer desktop, and then Li Xiao operated on it and opened a search website.

"Luo ...... Beautiful...... Fuzzy math ...... Shimen ...... Polytechnic...... Associate professor....... ”

Li Xiao entered several keywords in the search bar in a row, picked up the mouse and clicked the blue button on the right after typing, and in an instant, the page jumped, and lines of websites marked with red information pointed in front of them.
