This photo is very familiar to Su Yichen because there is the same photo in his pocket.

This was taken on the day the Galaxy Megacomputer project was completed. In the photo, his mentors, Professor Luo Shaohua and Professor Wan Changchun, stood in the middle. The three people on their left were Lu Yuanming, Yunmei and Lin Dong. Lu Yuanming is a disciple of Professor Wan Changchun and a lecturer in the Department of Physics of the University of Science and Technology. Sister Yunmei is Su Yichen's senior sister. She focused on electronic technology and gave Su Yichen a lot of help and care during the project team.

As for Lin Dong, he is an expert in microelectronics, and also an assistant teacher in the department. When Su Yichen first joined the project team, Lin Dong had awkward relationship with Su Yichen because it was Luo Shaohua's intention to join the project team. Lin Dong thought that Su Yichen was completely fussed with the project team because of his connection. He was very unhappy about this, and even said some weird words about using public instruments and being nepotist in front of everyone.

In that year, in order to save time and speed up the overall progress, the project team finally decided to adopt a modular design in terms of overall solution design of general integrated circuits, that is, to complete the module and then conduct overall assembly tests, and finally adjust this design idea.

Due to this idea, the entire project team is divided into various groups, and Lin Dong is one of the persons in charge. Once, when Su Yichen was reviewing the design of a single area module, he found that the electronic circuits of this part of the template had design defects, and immediately questioned Lin Dong, who was responsible for this part of the work, believing that the electronic circuit he designed was in conflict with the overall design, and if no adjustments were made, it would be possible to cause the failure of the entire general-purpose integrated circuit.

But when Su Yichen made his opinion, Lin Dong felt that he was simply worried, or was talking nonsense, because he had already done a detailed calculation when designing the template, and the design plan was calculated in detail after discussion by the project group. All theoretical data were based on evidence and even signed and approved by Professor Wan Changchun. How could this happen? Both sides expressed their opinions on this and argued with reason, and no one was willing to give in and started to make a fuss on the spot.

This disturbance not only attracted Lu Yuanming and Yunmei to persuade each other, but even alarmed Professor Wan Changchun nearby. Finally, Professor Wan Changchun made a decision after listening to the report. To be cautious, he paused all work and checked the previous data again in response to the questions raised by Su Yichen. At the same time, he also asked everyone to take into account the overall verification plan and conduct comprehensive simulations from local to overall to make the final verification results.

After the final result came out, what surprised Lin Dong was that Su Yichen's judgment was correct, and it was precisely because of Su Yichen's bold "confrontation" that saved the possible huge losses for the entire project team.

After experiencing this incident, Lin Dong, who was straightforward and responsible for work, did not blame Su Yichen, but instead changed his previous cold attitude and looked at Su Yichen with great admiration. After a while, the two of them became very good friends later.

Recalling the scene when Lin Dong argued over the issue of electronic circuits, Su Yichen couldn't help but smile, and at the same time, she felt infinitely emotional. After so many years, I don't know how Lin Dong and the others are doing now, and whether everything is okay?

Gradually, the eyes looked to the left of the photo. On the left of the photo, which was the right hand of Professor Luo Shaohua and Professor Wan Changchun, two young people standing in full bloom were Su Yichen himself and Luo Yan who was extremely concerned about. Although Su Yichen and Luo Yan in the photo were just standing as ordinary as others, if you look closely, you can find that their hands were holding each other under the photo, and their smiles were so bright and sweet in the eyes.

Standing in front of this familiar photo, for a moment, it seemed like I had returned to the past, back to the time I took the photo. Looking at the familiar faces in the photo, Su Yichen couldn't help but feel a little confused.

I don’t know how long it took, but it was not until a question that I returned Su Yichen to reality from his memories.

"This classmate..."

Su Yichen turned around and saw a middle-aged man dressed in a teacher standing behind him. The other party told Su Yichen that there would be a reception event in the exhibition room soon, so he hoped that Su Yichen could leave as soon as possible.

The other party’s reminder Su Yichen didn’t care. Anyway, he had seen everything he wanted to see here, so he should leave. Next, Su Yichen planned to go to the staff dormitory. If the old Red Mansion was still there, he wanted to see where his mentor and Luo Yan had lived. Thinking of this, Su Yichen nodded slightly to the other party, walked away from another door in the showroom.

As soon as Su Yichen walked out of the showroom, a group of people came from the door he had come in before. An old man with gray hair and about 70 years old walked in with several professors and school leaders. When the old man stepped into the showroom, Su Yichen's figure happened to leave from the other side, and his eyes accidentally flashed past his back. The old man was slightly stunned, and he felt that the back seemed familiar.

"Old Lin?" Seeing the old man stopping, a middle-aged man accompanied him asked with concern.

Old Lin looked at Su Yichen's departure direction, and Su Yichen had already walked away, and there was no empty figure there.

"It's nothing. I guess he's old and dazzled. He's old. This person is easy to be confused when he's old." Mr. Lin smiled self-deprecatingly, and the middle-aged man accompanied him laughed and said, "Mr. Lin, you are really good at joking. You are not confused at all. According to me, Mr. Lin, you are in good health. It's not a problem to work for more than ten or twenty years. We juniors still hope to listen to your teachings for a few more years."

"Yes, yes, Mr. Lin, you are a treasure of our Shimen University. Although you have gone to the Chinese Academy of Sciences, don't forget that this is your mother's home. We mother's family members are looking forward to you coming back to see it every year."

The other people on the side laughed and echoed. Mr. Lin laughed and pointed his fingers at them, saying that you guys have not improved for so many years and have become department chairs. They are also deliberately flattering themselves when they are professors. However, no matter how loud this flattery is, it is useless. He was just a stinky old man who was engaged in scientific research, and now he is a bad old man who is about to retire. He burns incense and worships Buddha to find the wrong person.

Although Mr. Lin said this, how could those present dare to take his words seriously? You should know that Mr. Lin was not only an old professor at Shimen University, but is now an academician of the Chinese Academy of Sciences. He has a very high status in the education and academic circles. Not to mention anything else, some of the people present were even disciples of Mr. Lin, who received almost the most important thing that Mr. Lin went back to Shimen University to visit him every year.

Speaking of Mr. Lin, he is a nostalgic person. Although he had already left Shimen University, he always took a few days every year to go back to the university. Especially this showroom is his must-pass place every time. Today is no exception. Accompanied by everyone, he came to the showroom, looking at the glass walls with honor and old photos, and telling others about the past.

Finally, when he came to the photo, Mr. Lin stopped and his eyes remained on the photo. His excited expression just now became lonely, and he even sighed lightly.

"Old Lin, tell us about this photo." Every time, Mr. Lin comes here, he will stand in front of this photo for a long time, but never tells everyone the story of this photo. Today, the department head who accompanied Mr. Lin, the middle-aged man standing next to Mr. Lin, couldn't help but ask boldly.

The eyes were taken back from the photo and looked at everyone. When he saw that everyone was curious, Mr. Lin hesitated for a moment before he said, "Okay, I'll tell you today..."

Mr. Lin told everyone the story behind this photo. Although there is a line of introduction written below the photo and the origin of the photo is marked on it, it is far from the story of the person involved. Mr. Lin started from the establishment of the Galaxy Mega Computer Project in 1979, and until the day the project was successfully successful in 1983. This photo was the main member of the Shimen University of Science and Technology who participated in the Yinhe Mega Computer General Integrated Circuit Project. Among the seven people in the photo, Professor Luo Shaohua is known. This is the old dean of the School of Science, and Mr. Lin is Lin Dong in the photo. As for the other five, Professor Lu Yuanming is not unfamiliar with him, but he died many years ago. Many of the remaining four people do not know their origins.

"This is Professor Yunmei. She was transferred to the Ministry of Aerospace Science and Technology in 1984 and died in an accident at the Northwest Aerospace Base in 1993. She is a very outstanding scientific researcher. Her sacrifice is a huge loss to my country's aerospace industry..."

"I have heard of this. Professor Yun was the leading electronics expert in our country back then. Unexpectedly, Professor Yun was also a scholar from our Shimen University." A young associate professor interjected, and Mr. Lin nodded slightly to him. Since Yunmei later worked in a confidentiality unit, the school did not publicly promote her due to some reasons. Unexpectedly, someone present knew about her.

"By the way, Mr. Lin, are these three..." No one expected that there was a person like Yunmei in the photo. Everyone was curious and proud, and someone pointed at the remaining three people to ask.

Mr. Lin looked at the remaining three people and didn't speak for a long time. Just when everyone thought Mr. Lin didn't plan to continue introducing, Mr. Lin said: "This lesbian is Luo Yan, the daughter of Professor Luo Shaohua. She was once the youngest associate professor at our Shimen University of Science and Technology, and is also the leading expert in fuzzy mathematics in China."

This sentence stunned everyone for a moment. Professor Luo Shaohua's daughter, the youngest associate professor at Shimen University of Technology and an expert in fuzzy mathematics? Why don't they know about this situation?

"It's normal for you to not know that she is, because Professor Luo Yan went abroad shortly after Professor Luo Shaohua passed away. Now I don't even know where she is. Speaking of the reason why she went abroad, it is actually related to another person in this photo."

"Are you talking about... this young man?" A sharp-eyed person in the crowd noticed Su Yichen beside Luo Yan from the photo, and especially found their hands holding each other, and couldn't help asking.

Mr. Lin nodded silently, and then introduced Professor Wan Changchun and Su Yichen in the photo to them. Although everyone had never seen Professor Wan Changchun, Professor Wan still heard of his reputation in the physics world. Moreover, Professor Wan suddenly disappeared in the northwest that year, which was a sensational event, and it still remembered many people deeply. But no one expected that the old man who was ranked alongside Professor Luo Shaohua in the photo was Professor Wan Changchun that year.

Unexpectedly, in addition to Professor Wan, Mr. Lin focused on introducing the unknown Su Yichen to everyone. What surprised everyone was that the young man in this photo was not only the old dean's personal disciple, but even Mr. Lin's evaluation of Su Yichen was extremely high in his words. According to Mr. Lin, if Su Yichen had not encountered an accident with Professor Wan Changchun and his whereabouts were unknown, then his future achievements would definitely be greater than that of himself. It was precisely because of Su Yichen's disappearance and Professor Luo Shaohua's death due to illness that Professor Luo Yan would be discouraged and resolutely resigned from his job and went abroad despite the retention of the school.

The past made many people present sigh. No one expected that there were so many stories hidden behind this ordinary photo. After saying this, Mr. Lin seemed a little sad and tired. He slowly left the showroom with everyone's persuasion. After Mr. Lin walked away, the middle-aged teacher who was waiting outside came forward to clean the showroom. When he walked to the photo, he accidentally looked up at the photo. He felt that someone in the photo looked familiar, but after thinking about it, he couldn't remember where he had seen it. In the end, he could only return to the illusion that Mr. Lin just told. The middle-aged teacher didn't care in his heart and quickly threw this matter behind.
