Material Empire

Although Yan Jiamin's warning was the only evidence for the whole incident so far, Xiao Weihao, like Qin Hai, did not think that this was a false alarm that had never happened. Xiao Weihao has heard many things about dismantling each other for the sake of competing for professional titles, academicians, etc. Of course, it was the first time for Xiao Weihao to personally take action and mobilize people to investigate this kind of matter. This was basically for Qin Hai's sake.

If Xiao Weihao wanted to use professional reconnaissance equipment and personnel, he naturally had to report to the unit. In the formal application for filing, he particularly emphasized the importance of iron-based superconductivity research to national military and economic security, explaining that this investigation is not out of personal affection, but a complete official business.

Xiao Weihao's leader also met Qin Hai once, knowing that this young chairman has done a lot of good things for the military industry system, and now that something is asked of him, how can he refuse. Therefore, although Xiao Weihao's application report had some flaws that could not withstand scrutiny, it was finally approved smoothly. A capable investigation team came to the Superconducting Research Center with various equipment.

Qin Hai didn't tell anyone about Zhang Shengying and Liu Jun's investigation. He just said that some colleagues who do material research hope to visit the laboratory. He is the funder of the research center, and Chen Zong would not refuse when he proposed which laboratory to visit, nor would he ask for specific reasons. In order to deceive others, Qin Hai, Xiao Weihao and his party did not go straight to Zhang Shengying's laboratory, but walked around other places first, and finally walked into Zhang Shengying's room inadvertently.

The time they chose happened to be when Zhang Shengying was teaching in the classroom, and Qin Hai thought of a reason to distract her graduate students. When Chen Zong heard that someone was coming to visit, he enthusiastically expressed his willingness to accompany him, but Qin Hai politely refused. Chen Zong only thought that it was Qin Hai's care for him, and he didn't think about any strangeness in it.

Xiao Weihao wanted to investigate all the computers in the laboratory. According to his analysis, if Zhang Shengying and Liu Jun want to do something, they probably need to write some written materials, such as anonymous letters. In the past, it was very troublesome to write anonymous letters. In order to prevent others from recognizing their handwriting, some people would write letters with their left hand, and some even pasted words cut from newspapers into a letter.

After you have a computer, it is easy to write an anonymous letter. Just type it out on the computer and print it out with a printer without leaving any handwriting. As for printers, they actually have their own fingerprints. Through technical analysis, it is possible to identify which printer a document came from. This is a relatively rare knowledge, and many people don't understand it.

If they used their own computer instead of the computer in the laboratory to write the anonymous letter, wouldn't it be impossible to find out? Qin Hai looked at the young men brought by Xiao Weihao lying on several computers He was busy looking up something in front of him, and said to Xiao Weihao in a prepared manner.

You're right. Xiao Weihao nodded and said, If they had a sense of anti-reconnaissance, they probably wouldn't write such documents on public computers.

Does that mean that you are still going to search the computers in their homes and dormitories? Qin Hai asked curiously, Is this a bit loud?

It's one thing to check a computer in a lab, but quite another to check Zhang Shengying's home computer. The nature of the former is not so serious. Even if Zhang Shengying knew about it, she would not be able to say anything. After all, these computers are public equipment and cannot be used for private work according to regulations, so there is no problem of protecting privacy. But if you want to check the computer at Zhang Shengying's home, it is a blatant violation of privacy. Although Qin Hai believes that Xiao Weihao has the ability to check without anyone noticing, it is not something glorious after all.

Hearing what Qin Hai said, Xiao Weihao smiled, and he said: It depends on the situation. Normally, we would not take such extreme measures. Of course, if there is evidence that they endangered national security, it would be difficult to say. .Our current reconnaissance is only looking for clues, as long as anyone does something, it is impossible not to leave traces.

While chatting, a scout named Lu Xiaotong called out softly: Ju Xiao, President Qin, come and take a look at this.

Xiao Weihao and Qin Hai walked over quickly, and saw a window open on the computer screen in front of Lu Xiaotong, with a string of file names and the corresponding time on it. Qin Hai took a rough look, but didn't see any tricks, so he couldn't help turning his surprised eyes to Lu Xiaotong.

This is the computer used by Liu Jun. What is displayed now is a list of documents that have been printed on this computer in the past two months. I checked just now, and all other files can be found on the hard disk, only this file...

At this point, Lu Xiaotong pointed at a file named Serenity and said, This file was printed directly from a floppy disk, and the printing time was two o'clock in the middle of the night.

That is to say, at two o'clock in the middle of the night, Liu Jun took a floppy disk from the dormitory to the laboratory to print a file called 'Serenity'? Qin Hai said.

No. Xiao Weihao said, he is specialized in intelligence work, and he sees problems far more comprehensively than Qin Hai. He pointed to other documents on the window and said, Look, before this, he also printed other documents. document, and finally printed this Serenity document. Obviously, he wrote this document first, brought it to the laboratory, and printed it out in the dead of night when no one else was present.

Serenity? Qin Hai recalled the meaning of the word in his mind, and before he could figure it out, Lu Xiaotong had already said it for him: President Qin, the Chinese meaning of this word is tranquility.

My_God! Is this okay? Qin Hai muttered. The word itself is a bit remote, and it is not easy to appear in scientific literature, so although Qin Hai's English is very good, he can't understand it all at once. After hearing what Lu Xiaotong said, he just remembered that this word really means Tranquility, could this Tranquility be that Tranquility, used to refer to his girlfriend?

Can you find out the contents of this file? Xiao Weihao actually thought of this a long time ago, and he asked Lu Xiaotong calmly.

Lu Xiaotong shook his head and said: The original file is on the floppy disk, but I can't find it on the hard disk. If it is a file that was just printed, I can find the print buffer file and restore it, but this file was printed a month ago. The buffer file has been overwritten by other files and cannot be recovered.

What are the documents printed before and after this, can you find them? Xiao Weihao asked again.

Yes, but they are all academic articles. Lu Xiaotong opened a document while speaking, pointed it to Xiao Weihao and Qin Hai, and said at the same time: It's all some experimental data, it's too professional, I can't understand it.

Samarium oxide iron arsenic? Qin Hai turned his head to look at the screen, and couldn't help frowning, This is an iron-based superconducting material. How could Liu Jun do experiments on iron-based materials?

Can you see what these data indicate? Xiao Weihao asked. Both he and Lu Xiaotong were incapable of dealing with such a professional matter, and the people in the security department were not encyclopedias. Such cutting-edge content is not involved.

Qin Hai picked up the mouse and dragged it, and quickly browsed through the content of the article. He could tell that this was an experimental report on the magnetic properties of iron-based materials, which had a strong relationship with Ning Jing's current doctoral thesis. . Since he is not particularly proficient in the theory of iron-based superconductivity, he can't see any problems with this report at once.

It's hard for me to judge now, but both Liu Jun and his mentor Zhang Shengying are engaged in copper-based superconductors, and Zhang Shengying strongly opposes her students getting involved in iron-based superconductors, so it was found on Liu Jun's computer that it is similar to iron-based superconductors. It is very abnormal for the paper of the director, especially when it involves the original experimental data. Qin Hai said to Xiao Weihao.

This is a tell-tale. Xiao Weihao nodded and said, Back up all the files on this computer, including files that have been deleted, and we will go back and do a detailed analysis.

Give me a copy, I'll show Tranquility, maybe she can guess the problem. Qin Hai said.

The subsequent inspection further confirmed Qin Hai's judgment. On Zhang Shengying's computer, he also found Liu Jun's experimental reports on iron-based materials. Technical analysis shows that Zhang Shengying has browsed this article more than once, and the most recent visit was a day ago.

Any abnormality is bound to be a demon. As intelligence workers, we pay special attention to such unconventional things. If a person does an unconventional thing for no reason, he will definitely be able to find the problem behind it. Xiao Weihao Said to Qin Hai.

I also have this feeling, but I don't know what they are going to do. Qin Hai said, However, it will be easy to find out their cheating feet. The feeling of being lost is really uncomfortable. .”

Okay, you take these articles, let Xiao Ning read them, hear what she thinks, and then communicate with me in time. Xiao Weihao patted Qin Hai's shoulder and said.

Thank you Xiao Bureau, thank you all. Qin Hai took the software that copied those articles and said gratefully to Xiao Weihao and others.

No thanks, no thanks. Xiao Weihao said with a laugh. After laughing, he put his mouth close to Qin Hai's ear and said, If you really want to thank us, then find some good projects for our department to do. Our department can generate more income... Now that housing reform is underway, young people worry about not having the money to pay for it.”
