In the following days, Meng Lin would often ask Su Yichen some questions, and Su Yichen was also willing to point him out. Meng Lin's talent in science is very good, otherwise he would not have been admitted to this key university with excellent grades, what he lacks is only pioneering ideas and some practical experience, after all, college students are a little different from Su Yichen back then, especially the weakest in terms of hands-on.

As a student who is about to be a senior, Meng Lin is also worried about his future prospects, the current society is not like before, more attention is paid to economic construction as the center, making money is the only goal of the vast majority of people, Su Yichen's reading era is not afraid to learn mathematics, physics and chemistry all over the world is not afraid of outdated, young people pay more attention to finding a good job with a good income and decent, as for whether the job has anything to do with their major, this is not considered at all, In their eyes, a college diploma is just a stepping stone.

Meng Lin still has some ideals in scientific research, but the facts are also in front of him. Just like Tang Wei at the beginning, he must make a choice between ideals and reality, unless he is favored by a certain tutor in college, or even enters a professional project as a member of it, so as to slowly accumulate his own capital in this way. Then, after graduation, you will have a wider range of choices, and you will be able to achieve both ideal and realistic results.

Tang Wei's story touched Su Yichen's heart, and after getting acquainted with Meng Lin, Su Yichen also knew that Meng Lin had always wanted to join Professor Ye Tianlong's research group in their department, so he would choose these hardware papers to prepare. After thinking about it, Su Yichen decided to give him support and help in this regard, so as to make up for Meng Lin's shortcomings in a targeted manner, and also put forward some key suggestions for him in writing his thesis.

With the help and guidance of Su Yichen, in just over a month, Meng Lin's progress was obvious, and he also wrote a very novel professional paper. It is this paper that has attracted the attention of the department, when Professor Ye Tianlong personally read Meng Lin's paper and felt very good, and then found Meng Lin to assess him on the spot, and the assessment results also satisfied him, Meng Lin compared with ordinary college students, in the design and application of general integrated circuits has some ideas, and the foundation is also solid, immediately asked Meng Lin if he was willing to join his research group, for the pie that fell from the world Meng Lin was of course overjoyed. In this way, a few days ago, Professor Ye Tianlong officially notified Meng Lin to absorb him as a new member of his research group, but as Meng Lin's current student, joining such a research group is only a member at the bottom, and most of the work he usually does is to help a "big boss" like Ye Tianlong or a "small boss" in the group to do chores.

But even so, not everyone in Professor Ye Tianlong's research group can enter, and having this opportunity is equivalent to writing a strong stroke in Meng Lin's academic career, which will make his choices much broader after graduation, and he may even get the opportunity to graduate and stay in school in the future. When he received this good news, Meng Lin wanted to tell Su Yichen as soon as possible and share his joy together, but he couldn't meet him in the library for a few days, Meng Lin didn't have Su Yichen's contact information, their meeting was always in the library, and he didn't even know where Su Yichen lived, so these days Meng Lin would come to the library at this time every day to have a look, and the effort paid off, and he finally met Su Yichen today.

"Not bad, yes, do a good job after joining the research group!" Su Yichen smiled and patted Meng Lin on the shoulder as encouragement, but Meng Lin knew very well in his heart that without Su Yichen's guidance, he would never be favored by Professor Ye. And these days, he has always wanted to thank Su Yichen, and immediately proposed to invite Su Yichen to dinner to express his gratitude.

Su Yichen smiled and shook his head in refusal, stretched out his hand to point at the journals he borrowed, indicating that he hadn't finished reading these journals yet. Meng Lin's gratitude was understood by him, and there was no need to eat, not to mention that the reason why Su Yichen helped Meng Lin was that he felt that he was a good seedling, and secondly, because of Professor Luo Shaohua's book.

"Brother Su, just give me this opportunity, or I'm really sorry in my heart, without your help, Professor Ye won't let me join his research group, if you don't even want to eat a meal, I'll ...... I....... Meng Lin couldn't think of suitable words to express his feelings for a while, and rubbed his hands in anticipation with an anxious expression.

Looking at Meng Lin's expression, Su Yichen couldn't help but be happy, and after thinking about it, he reluctantly agreed. However, he still made an agreement with Meng Lin for three chapters, it is okay to go to dinner, but he will definitely not go to the big hotel, just find a small restaurant near the university town, otherwise Su Yichen would rather not eat this meal.

"No problem, no problem!" Seeing that Su Yichen finally relented, Meng Lin nodded happily. Of course, he also knew that Su Yichen did this because he was a poor student and didn't want to break the bank, and he was even more grateful to this eldest brother in his heart.

After returning the borrowed periodicals first, Su Yichen and Meng Lin left the library together and walked out of a street, in front of which was the food street in the university town, which was a favorite place for students from several nearby universities, including residents, because of its affordability and a wide variety of delicacies. found a relatively clean shop, the two walked in, and ordered a few side dishes, originally Meng Lin wanted to order more but stopped Su Yichen, it was already hot this day, not to mention that it was two people eating, and it would be a waste if they ordered too much to eat, these meals were enough.

"Why don't you have some drink?" Meng Lin asked.

Su Yichen didn't have an opinion, so he asked the boss to take two bottles of beer, and after pouring it full, he took the initiative to salute Meng Lin first, congratulated him on entering Professor Ye's research group, and also encouraged him.

After clinking glasses, Meng Lin helped Su Yichen fill up the wine, and then the two chatted while drinking. In his words, Meng Lin greatly admired Su Yichen's professionalism and level in general integrated circuits.

Meng Lin was also curious about Su Yichen's personal situation, and he always thought that Su Yichen was likely to be a researcher at that research institute, or another university teacher or something. With the strength of the wine, Meng Lin couldn't help but ask this question, who would have thought that Su Yichen smiled and shook his head in denial, telling him that he was just a junior high school physics teacher in a private middle school.

"What!" When he learned that Su Yichen was just a junior high school physics teacher, Meng Lin was extremely surprised at first, and then he was very upset for Su Yichen, in his opinion, with Su Yichen's level in this regard, let alone a junior high school physics teacher, even if he was a lecturer in a university, it was more than enough.

"Brother Su, do you want to come to our school, let me introduce you to Professor Xia, it is absolutely no problem to enter our research group at your level, maybe Professor Ye can help you solve the title evaluation, no matter what, being a teaching assistant in a university is better than a junior high school physics teacher, right?"

Meng Lin kindly helped Su Yichen come up with this idea, in his opinion, Su Yichen's current job is too condescending. But who would have thought that Su Yichen just smiled and shook his head, rejected Meng Lin's kindness, and even made a request that made him unbelievable, that is, no matter who he was, he couldn't mention his own affairs, even in front of Professor Ye Tianlong, and he couldn't mention that he had guided Meng Lin.

"Why?"

"No, it's just a small favor for your brother Su." Su Yichen said lightly.

"But ......." Meng Lin really couldn't figure out why Su Yichen asked for this, and was about to persuade him again, but at this time, Su Yichen waved his hand and stopped him from talking.

"If you still treat me as a big brother, do what I say, or we won't have to meet again in the future."

Su Yichen's insistence made Meng Lin really entangled in his heart, and finally nodded in agreement, but he felt deeply sorry for Su Yichen's talent being buried.

"By the way, is your project team working on a topic about computer chips now?" After eating a mouthful of food, Su Yichen seemed to think of something.

Meng Lin nodded, in fact, domestic research on computer chips began in the late 70s, reached a peak in the 80s, and achieved great success, Su Yichen participated in the Galaxy project is one of them, the success of the Galaxy giant machine at that time caused a sensation in the whole world, even the United States has to admit that the Chinese's computer technology has reached a very high range. However, in the mid-90s, with the death of the old group of computer people, coupled with the great changes in the Soviet Union and the division of the country, the United States, as the sole superpower, adopted a series of tactics against China, which led to the emergence of an idea that it was more convenient to engage in spontaneous research than to take it, thus suspending China's independent computer research and development, including the core part of the computer -- the central processing unit.

This situation did not begin to change gradually until the beginning of the 21 st century, with the increase of national strength, the country only found that there is no independent research and development to be subject to the embarrassing problem of others, in order to change the current situation, the relevant departments have re-established independent research and development of computer projects, but due to more than ten years of technological fault, coupled with the current rapid development of computers, how easy is it to catch up again? No matter how difficult it is, this thing still has to be done, so similar projects have been established in major science and engineering colleges, and the same is true of Meng Lin's school, and the research group led by Professor Ye Tianlong is also conducting research in this area.

"Brother Su, you don't want to ......?" Hearing Su Yichen mention the matter of the research group, Meng Lin's face was happy, and when he thought that Su Yichen had changed his original intention, Su Yichen smiled and said: "Don't think about it, I don't have any interest in your subject, I just want to ask if your school has equipment like a mainframe computer." ”

Meng Lin was stunned, he didn't expect Su Yichen to ask this, but out of trust in Su Yichen, he nodded and said, "Yes, Professor Ye's research group will use it in many aspects of work. ”

"Do me another favor." Su Yichen directly made a request, he wanted Meng Lin to help him use the school's large calculations to perform a few number jù operations if possible. As for the calculation formula, Su Yichen will provide it to him, and Meng Lin only needs to input the formula number jù into the computer, and then hand over the final calculation result to him.

The reason for this request is that Su Yichen just remembered that although he has optimized the computer system, the efficiency of computing can be carried out with the limitations of ordinary personal computers is too low, and with his current ability, he cannot get professional-level large-scale computing, or even the use of supercomputers. Now that Meng Lin has entered this research group, it is very likely that they have this kind of equipment in their school, and if they can use a mainframe computer to assist in calculations, then Su Yichen's work progress will be much faster.

Although he didn't know Su Yichen's intention in doing this, he didn't understand what kind of arithmetic operation he actually needed to use a tool like a mainframe computer. However, Meng Lin still agreed without any hesitation, but he also frankly told Su Yichen that the use of mainframe computers has strict regulations in the school, and even if he enters the research group, it is difficult to get in touch with it immediately, so it will take a while, but as long as there is an opportunity, Meng Lin will definitely help with this.

Meng Lin agreed to this, which made Su Yichen very happy, with a mainframe computer, the next work could be much faster. A few days later, Su Yichen selected some of the most complicated formulas and handed them to Meng Lin, Meng Lin didn't understand what these formulas were for, but he still solemnly put them close to him.

In the next two months, Meng Linshun entered the research group to start working and studying, and often came to the middle school to communicate with Su Yichen in his spare time. With the beginning of his study work in the research group, Meng Lin deeply felt that he was deficient in many aspects, when he sometimes asked Su Yichen for advice on the problems he usually encountered, Su Yichen would patiently and carefully explain and analyze to him, with Su Yichen's help and teaching, Meng Lin's professional level improved rapidly, and in the autumn, Meng Lin used his good performance to get Professor Ye Tianlong's praise, so that he was promoted by the most basic member to a level.

After being promoted to the level, Meng Lin finally had the opportunity to directly contact the mainframe computer, and he had never forgotten the promise he had made to Su Yichen, and he also began to help Su Yichen calculate those formula numbers jù, at first he thought that such operations should be completed soon, but when the first formula number jù operation took a full week to produce results, this surprised Meng Lin.

You must know that this is not an ordinary personal computer, but a highly professional mainframe computer, although the school's mainframe computer is much worse than the most cutting-edge foreign computer, but its computing speed is also extremely amazing. He never thought that it would take so long for Su Yichen to hand over the formula jù operation, what was the use of these numbers jù? Why is it so large and complex? These questions lingered in Meng Lin's heart, and at this time, he finally understood why Su Yichen would entrust himself to do this, because it would take almost half a year or even more to perform calculations according to the fastest personal computer on the market.

When the results of the number jù came out, Meng Lin wanted to tell Professor Ye Tianlong about it, and wanted to find out what these formula numbers were used for, but in the end, the promise to Su Yichen still made him dispel this idea. When he handed over the result of counting jù to Su Yichen, Su Yichen was extremely happy, and immediately turned on his computer and entered the number jù into it.

"Thank you Xiao Meng, you can help a lot!" Su Yichen finished typing the last number, and thanked Meng Lin with the excitement in his heart, and at this time, Meng Lin glanced at the strange program on Su Yichen's computer, this computer was not the first time he had come into contact with it, but he never understood how the program used by Su Yichen was so strange, it seemed to be a bit like the Linux system, but it was very different from the Linux he was familiar with.

"That's as it should be, but there are a few formulas that are estimated later." Meng Lin said with a smile, and deliberately explained the situation, because from tomorrow, the university will have several foreign scholars to do academic visits, and for this reason, the use of important equipment such as mainframe computers will be suspended, and even their research group will be on vacation for a few days.

"It's okay, just wait until they're gone." Su Yichen nodded in understanding, and then casually asked about the situation of the academic visiting scholars, Meng Lin told him that these scholars are professors from several famous universities in Europe and the United States, and several of them are famous figures in physics today, when he mentioned a few names, Su Yichen didn't care, but when Meng Lin said the last name, Su Yichen was stunned for a moment, and suddenly raised his head.
