Lu Nan's efficiency was really fast, I asked him to check it for me only two days ago, and a day later he told me that he had found the records of the post office where Rena received and sent the letters, and he assured me that there was absolutely a way to find the person who received and sent the letter. Another day passed, and Lunan made good on his promise.

"Who is it?" Lunan's words immediately made me solemn, I never thought about sending letters to Rena and the recipients of Rena's mail. I would have known.

I only met Lu Nan in the past two months, and the people I and Lu Nan know are indeed only people who may have been haunted in Chongqing City. Several figures flashed in my mind, and Lu Nan no longer sold Guanzi, he told me directly: "Professor Li, the person who sent the letter to Rena and received the letter from Rena is the person who bought and killed you before. ”

My heart sank suddenly, and the several figures that flashed in my mind disappeared one by one, and finally a person was left, and his face slowly became clearer: Tang Yingxuan! This feeling is very strange, Tang Yingxuan seems to be really in my mind, Tang Yingxuan in the imaginary world is also cold and resolute, the difference is that more mysteries seem to have been added to his body.

Tang Yingxuan, a veteran, has excellent skills and marksmanship. Calm and decisive, indifferent and rejecting people thousands of miles away. and Gao Xufan, the companion of the strange man in red, hated each other and lived alone, but they did things for the forces behind Shen Cheng, and wanted to kill me for inexplicable reasons.

Tang Yingxuan's various information quickly and automatically analyzed in my heart. I've noticed that I'm surrounded by more and more mysterious people, some of whom I don't know or aren't sure who they are, such as the weirdos in red, the mysterious men, and the guy who is good at imitating voices.

And some, I know who they are, but I still think they are mysterious, such people include Shen Cheng, Shen Nuo, Seventh Uncle, Du Lei who hides marksmanship, and so on. Tang Yingxuan belongs to this kind of person, I have had a lot of contact with Tang Yingxuan, but as time goes by, instead of knowing him better, I feel that he is even more strange.

Tang Yingxuan. He was no less mysterious than anyone else I had met.

When I was in Yushi, Lu Nan had already found out that Tang Yingxuan was the one who bought and killed me, but I already knew about it, so I didn't let him tell it. The news that Lunan told me was very important, and although I had great trust in Lunan's reconnaissance ability, I had to confirm the accuracy of the investigation with Lunan.

"Professor Li, I have repeatedly investigated and verified, and the results will not be wrong." Lu Nan confirmed to me again.

Lunan's method of investigation was similar to what I had previously speculated. When the sender sent the mail, he did not write his name and address, so Lu Nan had no way to directly investigate the identity of the sender, but the address and name of the recipient Rena were confirmed.

Therefore, according to the name of the recipient, Lunan checked the relevant records of the post office and finally determined the delivery date of the letter addressed to Gena. So, Lu Nan randomly selected a few days of so many dates and compared the surveillance video, and soon, Lu Nan found the same figure in the surveillance video: Tang Yingxuan.

At first, Lu Nan thought it was just a coincidence, so he randomly selected more shipping dates, but after such verification, Lu Nan still found that Tang Yingxuan appeared at the post office in those days. Moreover, Lu Nan asked the criminal police to search repeatedly, but finally failed to find other identical and repeated figures in those dates.

"I'm afraid of making mistakes, so last night I asked my subordinates to investigate in more detail the surveillance video of more than 200 days, and Tang Yingxuan appeared in the post office every day." Lunan said.

One day or two, it may be a coincidence, but more than two hundred letters, more than two hundred days, every day in that post office seems very abnormal. Moreover, in the absence of other duplicates, Tang Yingxuan has indeed become the biggest suspect in this way.

"Originally, I was worried that the real sender would deliberately let different people send the mail, but God still favored us." Lu Nan said again.

I had that concern before. If there is an ulterior secret in the letter, then the sender is likely to ask a different person to send it, after all, it is very easy to give a small benefit to an ordinary person to go to the post office to post a letter. If that were the case, the method of identifying the sender by finding duplicates would not be available. It is the blood of the history of the pool.

Tang Yingxuan can basically be presumed to be the sender, which also makes me think about why Tang Yingxuan didn't let others send the mail. Tang Yingxuan's actions are very likely because of the forces behind him, in that force, there is no freedom, which can be seen from Shen Cheng and Shen Nuo, and Tang Yingxuan naturally has no one.

Therefore, the mail, most likely, is also an order of that force.

Whether it was that force or Tang Yingxuan, they were undoubtedly extremely smart, and they would not have thought that letting different people send the mail could reduce the possibility of being found out by anyone who was the real sender. But they didn't, and soon I thought of a possibility: the content of the letter was very important.

If you casually ask a stranger to give benefits and ask them to submit the letter, that person is likely to open the letter out of curiosity, and may also have worries about whether the other party will let him do something illegal, and may even tell others that this is undoubtedly a huge threat to the confidential letter of the letter.

And the fact that the force did not let different people in the force send the mail is enough to show the importance of the content of the letter, and the fewer people who know about it, the better. So that force has always asked Tang Yingxuan to send the mail alone.

Tang Yingxuan's ability is undoubted, letting Tang Yingxuan send the mail is a trust in Tang Yingxuan, and on the other hand, that force probably didn't expect that one day someone would investigate them through the post office and surveillance, and even, after Rena received the letter, she burned it after reading it.

In such a roundabout and complicated way, it is very difficult to find out who is receiving the letter. In other words, I'm afraid that the forces didn't expect that Rena would be involved in the case of the woman in red and get my attention, and finally come to Fanshi to investigate.

Rena communicates with that force, and the purpose of Na Rena's stay in the village is the same as the purpose of that force, and they want Rena to investigate someone or something. All of a sudden, my brain automatically analyzed a lot of possibilities.

If Rena knows that she shouldn't know, or betrays the forces, the forces want to kill Rena, they can be quiet, there is no need to make such a big noise, which will expose the secrets of the forces. I've been in contact with a lot of people in the forces, and in their eyes, they have their own understanding of morality, so it's unlikely that they'll kill Gena.

Therefore, Zena's death should have come as a surprise to that force.

The criminal police who went to the Fanshi Post Office to investigate told me that in the past two months, the letters that had been hoarded in the post office and addressed to Rena were taken away at one time, and there were no new letters after that, which may also be sent by Tang Yingxuan and the forces behind him to pick them up, because Rena died several months ago.

However, the forces had no way to learn of Rena's death for a while, so they kept sending mail to Rena. The number of Gerna's shipments is much smaller than the number of receipts, which indicates that Gerna's order to reduce the chance of exposure will only be sent when there is something important.

Therefore, even if Zena did not reply for more than a month, that force would not be suspicious, after all, their actions were very hidden. It wasn't until a few months after Rena's death that the forces probably sensed that something was wrong, so they sent someone to the city. The person who sent the mail was Tang Yingxuan, and the person sent by that force to Fanshi was also Tang Yingxuan, which is probably not a coincidence.

After thanking Lunan, I immediately hung up the phone and rushed into the desert. Tang Yingxuan had just led the camel into the desert, his speed of action would not be too fast, I had to stop him and ask him clearly! Tang Yingxuan told me that today would be his last day investigating the desert and his last day of service for that force.

This means that Tang Yingxuan is about to break away from that force, I don't know if this is allowed by that force or Tang Yingxuan's own decision. If it was Tang Yingxuan's own decision, I don't know how that force would react after learning of Tang Yingxuan's decision.
