Seeing that Shi Lei and the others didn't answer, Yuan Muye continued to ask, "You tell me the truth, did that Sui Guangnan give you a little sweetness at the beginning?" Otherwise, how could you give him 50 million so easily? ”

Before Shi Lei could speak, Ah Zhe swore to the sky and said, "Are we going to take those things and strike five thunders in the sky?" ”

It is estimated that even Shi Lei didn't expect Ah Zhe to say such childish words, so he had to say to Yuan Muye a little speechlessly, "I don't know how to say it to believe it, but we really didn't get anything!" The reason why we gave Sui Guangnan money first was because we received rumors that the institute would submit an important experimental report to the government in the near future, and this report was related to a cutting-edge high-tech equipment...... In order to seize this opportunity, we had to pay Sui Guangnan first. If it weren't for the shame of saying it, I wouldn't have asked you to come over and help. ”

Although Yuan Muye was a little gloating in his heart when he heard this, he still said with a sympathetic look on the surface, "Then you can get the money back?" If you don't come back and grab it back?! ”

Who knew that Shi Lei said with a depressed expression after hearing this, "Do you think we haven't tried?" But this Sui Guangnan does not leak anything, he has no bank account, the house he lived in before his death was rented, and even his only relative died of illness three years ago. We almost dug all the places he had been in, but we couldn't find anything......"

Yuan Muye said thoughtfully when he heard this, "Have you ever thought that it is impossible for a person to be completely out of touch with this world, if he really has no relatives and no reason, then what is the use of him asking for this money?" ”

When Shi Lei heard this, he shook his head and said, "We have really searched all the places we can find......

Yuan Muye thought for a while after hearing this, and then said to Shi Lei, "In this way, use your information network to find out this Sui Guangnan's personal information, don't give me the official one, I want all the details of him from birth to death, including which hospital he was born in, which kindergarten he attended, and what elementary school he graduated from...... Check it all out for me. ”

Yuan Muye saw that Shi Lei didn't agree immediately, so he asked suspiciously, "Can't you find it?" ”

Shi Lei smiled after hearing this and said, "Give me a day......

After sending Shi Lei and Ah Zhe away, Yuan Muye whispered into the air like a psychopath, "Li Chen? Are you still there? ”

As a result, after he shouted twice, there was no reaction in the room, and it seemed that the other party should have followed Shi Lei and the two of them out together. Thinking of this, Yuan Muye couldn't help but secretly breathe a sigh of relief, in fact, he had been sweating for that kid since just now, although he had stealth equipment on his body, what if he was hit in a relatively narrow place?

After that, Shi Lei and Ah Zhe left for a day, and Yuan Muye also watched American dramas in the room for a whole day, during which no one appeared again in the fake Li Chen and the real Li Chen......

Just when Yuan Muye was about to stop staying and wanted to go around the corridor, the door was suddenly opened, and Shi Lei walked in with a thick stack of A4 paper in his hand, and said, "Here, this is all the information you want......

As soon as Yuan Muye heard it, he took it and sat on the sofa and looked at it carefully, the information shows that this Sui Guangnan had a not very happy childhood, he lost his father since he was a child, and after his mother took him to remarry, his stepfather has always been not very good to him, and he often beats and scolds.

Sui Guangnan was admitted to the hospital when he was twelve years old, but his mother insisted on refusing to call the police, not saying that her son was naughty and fell and injured himself. It is estimated that his mother should have her own plans in her heart, after all, it is not easy for a woman to raise her children alone, so she will always live with compromise......

Sui Guangnan officially left that home after going to university, and he didn't go back to mourn until his mother died of illness three years ago, and before that, he didn't go back once. His grades in school were average, but fortunately, he was very motivated, and he was a bit bent on getting ahead.

He joined the Lihai Research Institute after graduating from graduate school, and he has been working for five years, if he doesn't do this, he should also be a promising scientific researcher......

Because the information that Shi Lei got back was too trivial, Yuan Muye had to go through it carefully in order to find out the hidden clues hidden in the details, especially some consumption records.

Through analysis, Yuan Muye found that Sui Guangnan had always had a record of buying envelopes and stationery during his lifetime. But in these years, everyone has used mobile phones and emails to contact each other for everything, and who will write letters to each other with pen and paper?

So Yuan Muye pointed to one of the consumption records and said to Shi Lei, "What do you think Sui Guangnan plans to do when he buys envelopes, stationery and stamps?" ”

After hearing this, Shi Lei glanced at the consumption record and said, "If you just buy envelopes and stationery, it means that Sui Guangnan wants to write a letter that is not intended to be mailed, that is, the kind of letter that is given to the other party in person, or directly stuffed into the other party's mailbox." But since he bought the stamps together, it proves that the letter should be a letter to be sent. ”

Yuan Muye nodded and said, "If you look at these consumption records, Sui Guangnan basically has to buy them every month or two...... This proves that his contact with the other party is fixed and frequent. Let's go to a few post offices near Sui Guangnan's house, and maybe find out where these letters ended up. ”

Then Shi Lei took Yuan Muye out of their group's building and went to several post offices in turn...... According to the time when Sui Guangnan bought the envelope, they then retrieved the surveillance video of several post offices near his home, and sure enough, they saw Sui Guangnan's figure in front of the post box outside one of the post offices.

Although the exchange of paper letters is too primitive, this is now the most secret and safe way to communicate, if it were not for a careful person like Yuan Muye, ordinary people should not find that Sui Guangnan has the habit of sending letters. Moreover, in country M, this kind of ordinary letter usually does not record detailed logistics information, so it is difficult for ordinary people to find out where the mailed letter is sent.

As a scientific researcher, Sui Guangnan's life is full of high-tech elements, but he chose the most primitive way of communication, which alone is already very suspicious.

From the perspective of time, this should be the last paper letter sent by Sui Guangnan before his death, and he had already received Shi Lei's money and taken away the experimental data in the scientific research institute at that time.
