When I heard about the city, I jumped out of my chair, and both Adili and the detective who came back to report were taken aback by me, they may not have any special feelings about this city, but I am different. Chongqing City. Since I got there, there have been quite a few cases that have caused headaches for the police, from the two-headed man case to the killer organization case.

Besides. I came into contact with the forces behind Shen Nuo in Yu City, Shen Cheng, Tang Yingxuan, Uncle Fan, Uncle Seven, and the mansion for the forces to hide. For me, this city is not destined to be an ordinary city, and now, is it just a coincidence that the letter that Rena received actually came from Chongqing?

Since the 330 bus reappeared in G City, I have encountered many cases, among these cases, except for a few cases, the others have an inexplicable relationship with the big cases I want to investigate, Kuta Village is related to Sun Xiang's key, and the headless female corpse is related to Xu Yi's bracelet, so the case I am investigating now must have an unprecedented connection with the case of the woman in red.

"Tell me the specifics." I took Adiri and the detective out of Doha's house.

Doha helped me a lot during the questioning of the villagers, most of whom were reluctant to provide testimony. So the last people to be questioned were Doha's parents. There are only three relatives of the deceased. I gave Doha a look, and she smiled back and motioned for me to go, and she would keep someone for me.

When we arrived at a place where there was no one, the detective saw that my face was solemn and did not dare to be careless, so he quickly talked about the results of his investigation. There is only one post office in the city, and the postman is only responsible for delivering letters from the main city, and the letters of the people in the village need to be picked up at the post office by themselves.

Because of this, many of the village's letters are hoarded at the post office, because there are no telephones at home. When people who go out write letters home, relatives and friends have no way to know about them at the first time, so they can only go to the post office every once in a while to see if there are any letters of their own.

The detective sent out by Adiri was also smart, and he asked the person in charge of the post office to search for any uncollected letters from Gena. After all, Rena disappeared in a hurry, although the criminal police who went to confirm the DNA have not returned, but the headless female corpse is Rena nine times out of ten.

So. Before Rena's disappearance or death, it is likely that there were still uncollected letters. The post office went through all the letters that had been hoarded in the post office in recent months, and throughout the afternoon, with the help of the police staff, the detective confirmed that there were no outstanding letters from Rena in the police station.

Due to the imperfection of the postal system, there is no detailed record of the sending and receiving of letters in the post office, and the most detailed record is which municipal administrative unit the letter is sent to, or from which administrative unit the letter comes. Unable to find Gena's unreceived letters, the detective had to flip through the post office records page by page.

In this search, the criminal police found that in the past few years, Rena has delivered more than 100 letters at the post office in Fanshi, and the destination of the letters is Chongqing City. In recent years, the post office has recorded that Rena has signed and received more than 200 letters, and the origin of the letters is also Chongqing.

This coincides with my speculation: the ashes left behind by the windowsill of Gena's house are the letters she burned.

Hearing the number of letters sent and received by Rena, I fell into deep thought. There are no more detailed records in the police station, and I can't be 100% sure that the person who sent the letter to Rena is the same person who sent the letter to Gena, but they are both in Chongqing City, and it is very likely that they are the same address and the same person.

Generally speaking, when you receive a letter, you will reply to it, and the number of letters received and sent should not be so different, but the number of letters received by Gena is more than twice as many as those sent by Gena. I paced back and forth, wondering what could have caused such a big difference in the number of items received and sent by Rena.

According to previous speculation, Rena may have had a purpose in the village, and she burned the letter she received, which must have had an unspeakable secret, or very important information. Of the more than two hundred letters, each of which was burned by the windowsill, accumulated for a long time, and without wind and rain, it was no wonder that there were some ashes in the corners of the windowsill.

Rena needs to burn the letter, which is likely related to Rena's purpose in the village. Soon, I came up with the possibility that if Rena stayed in the village, without making money or killing anyone, it was probably because she was trying to observe someone or something. If my speculation comes true, then the gap between the number of letters received and the number of letters sent by Zena can be explained. It is a blood conspiracy.

Rena stayed in the village for several years, and if she was really on an observation mission, it meant that the object of her observation had not changed much, and she needed to be observed all year round. And the letter sent by Rena was probably someone reporting the results of her observations, and Rena stayed in the village on the orders of the sender.

For so many years, the sender needed to pass on his wishes and instructions to Gena, so he sent more letters; Rena didn't notice much change in the object she observed, so she sent far fewer letters. At this point, the next thing to speculate about is what Rena is observing.

The biggest possibility is that Rena is observing and monitoring that strange desert, because the strangest thing about this place is the desert where the coffin was found. And if Rena is observing people, then the object of observation may be Uncle Man, because so far, I have only found Uncle Man's anomaly.

But that's all just speculation on my part.

"Is there no way to determine the address or identity of the sender and the recipient in Chongqing?" I checked with the detective again.

The criminal policeman shook his head: "Professor Li, I have already asked the post office in Fanshi, and the information recorded is incomplete, so it is impossible to find the person who sent and received the mail." ”

I frowned and thought about it for a while, and then I asked the criminal police if there was anything else I found at the post office in Fanshi. Soon, the detective told me another piece of news that shocked me: in the past two months, Rena had signed for the letter.

Gina had disappeared months earlier, and if she had been a headless corpse, she would have been dead months earlier, and I immediately realized the gravity of the matter: it was probably not Zena herself who signed the letter.

The system management of the post office is not strict, generally as long as the recipient's name and sender's address are known, the letter can be signed, and the recipient only needs to sign it. Two months ago, there were still a few letters from Genna's hoarding in the post office, but the post office has never received any letters from Gena since they were signed for at once.

I stepped aside, took out my mobile phone and called Lunan, the signal in the village was not good, I tried several times before finally dialing Lunan's phone. As soon as Lu Nan answered the phone, he immediately asked me how I was investigating in Fanshi.

"I don't have a clue for the time being, and there is no progress on the events to be investigated." I replied to Lunan like this.

Lu Nan said on the other end of the phone: "Don't worry, I heard that Fanshi has been blocked, look for it slowly, you can always find someone, if you need my help, you can just ask." ”

I didn't shirk either: "Captain Lu, I have a favor that I need your help with now, it's very important and urgent." ”

Lu Nan didn't know what I wanted him to help with, so he agreed.

After thanking Lu Nan, I made my request. I asked Lu Nan to go to the post offices in Chongqing City to investigate for me and see if I could find out who the sender of the letter sent to Fanshi Rena was. Although the sender's name and address are not required to be sent, there are not many letters sent to Fanshi, and Chongqing also has the most developed surveillance system in the country, so as long as you find the date of sending the letter to Rena, you can narrow it down through the surveillance camera.

After hearing my request, Lunan immediately went to do so.

After hanging up, I went back to Doha's house again, and everyone was a little impatient to wait. It was getting dark, and on the first day I was asking for information about Rena, and on the second day I was asking about the victims of the three deaths, and now I asked another question that I wanted to ask: who else was there besides the village chief, who else had gone into the desert to look for the coffin.
