I didn't tell Zhang Ziang about seeing Team Nie, and naturally I didn't say anything about the iron box.

I carefully put away the iron box, and Team Nie didn't contact me until the next day. The next day, I reported to Team Fan about the file Z-70, and Team Fan gave me a letter to retrieve the file, so I went to the Archives Bureau with Zhang Ziang.

This is the largest archives office in the city, basically all the relevant archives are hosted here, and the division of labor of the entire archives bureau is also very complicated, I don't understand these very well, so I don't say much, Zhang Ziang and I went to the seventh floor, there are almost no people here, I'm afraid no one comes for a day.

When we arrived at the front desk, we needed to be strictly registered, especially our identification, although our identities were confidential, but we still had special team membership cards. Confiscated our mobile phones and a series of other things that may leak files, we can only go inside after registration, there is a special staff to receive us, we are greeted by a woman of about forty, she took our access letter and read it, and entered the access number in the computer, and only after confirming that it is correct and said to us: "Z files can not be taken out of the archives, according to the relevant procedures, you can only read on the spot." ”

Team Fan had thought about this before we came, and he said that if the file could not be taken away, then Zhang Ziang and I would read it, so the staff went to get this file and took us to a separate reading room, she said, "You have 60 minutes to read." ”

Then she left, and I opened the file, thinking to myself that with such strict rules, it seemed that this Z-70 file was not ordinary.

When I opened it, I found that it was a case file, and when I saw it, I understood why there were so many pig carcasses in the basement of that yard.

This is a pig's head corpse case, it seems that this person should be the owner of this yard in the past, called Meng Guangwen, and what is even more surprising and even weird is that whether it is the yard or the room where the butterfly girl lives, it is the property in his name, and Meng Guangwen is the real adoptive father of the girl, that is to say, the girl's parents we saw later are already the girl's second adoptive parents.

According to the file, Meng Guangming is humble and polite on the surface, but he is a murderer behind his back, and his method of killing people is very special, every time he kills someone, he must first kill a pig, and then take off the skin of the pig's head completely, and then wear it on his head, looking like a pig-headed man, and the file also comes with a photo of him with a pig's head face, which looks really eerie, even a pig's head.

It is impossible to know how many people Meng Guangwen killed, because he specially selected those who were alone, alone, or unrelated and unrelated to kill them, and the whereabouts of these people were the most difficult to grasp, which is why he kept killing people but never found out. There is also the way he disposes of the corpses, the bodies of the people he killed are gone, and the bodies cannot be found. The reason why his criminal deeds were discovered was because of a very terrifying video, only about ten seconds, which was a video of him walking with a pig's head in the dark, which was sent from an email account to the local criminal investigation department, and after watching it, the criminal investigation department felt that something was wrong, so he followed a series of clues to arrest Meng Guangwen, and when he was captured, he also found the body of half a person, the reason why it was half a person was because the corpse was indeed only half cut off, and the upper body did not know how to be disposed of, and it was gone.

When she was captured, Meng Guangwen's daughter, the missing girl, was only three years old.

Meng Guangwen was captured in this way, but he didn't want to say how many people he killed, but he also admitted to killing the body he found, and what he said was detailed, how he targeted him, how he tricked him into coming to his house, how to kill again, the whole process was very detailed, the logic was very clear, and it was also very calm.

But about the destruction of the corpse, he didn't say anything, no matter how he asked, there was no progress in the final trial, a public prosecution was carried out, and he was finally sentenced to death, after the execution of the death penalty, the case was settled, but more mysteries also followed Meng Guangwen to the underground.

The couple who continued to raise the girl were Meng Guangwen's only distant relatives, they chose to raise the girl, and lived in Meng Guangwen's building, as for the courtyard, no one went into it again, and it was almost deserted.

And the strangest thing is that the person who was killed by Meng Guangwen has not found out what his identity is, and he can't even determine his identity, so he was finally moved to the crematorium for cremation, and the ashes were placed by the funeral home in the crematorium.

After reading it, I was almost sweating profusely, and there was no record that there was a basement in his yard, and the existence of the basement was probably not found, but I thought it was unlikely, because the case was so big at that time, it was impossible not to search his house in a carpet way, so the only explanation is that this basement was built after Meng Guangwen's death.

I didn't continue to think about it, I asked Zhang Ziang: "Do you understand?" ”

Zhang Ziang nodded and said, "What about you?" ”

I said, "I have understood the general facts of the case, but there are still many things that I don't understand. ”

Zhang Ziang said: "Now is not the time to talk about this, we must keep in mind the content of the case file, especially some details, like this case, many times ignoring the details will ignore the whole case." ”

So although we had already finished reading it, we still looked at it again from the beginning, until we saw a photo of Meng Guangwen in the house, and I saw that there seemed to be a painting in the blurred background behind him, so I took the photo and looked at it for a while, and I said, "I have seen this painting." ”

Isn't this the sketch-like painting I saw in that strange mountain village with Duan Jiaming's name written on it?

After discovering this detail, I looked at other photos, trying to find out something from the background and some small features on my body, and finally I really found some very subtle and detailed places, I said to Zhang Ziang: "These photos appear in the case file, not accidentally, but inevitable, you see." ”

I pointed out this common place to Zhang Ziang everywhere, and there were a total of photos attached to this case file, and in each photo, there was a mark that I thought about, or it could be called a symbol, in different places, sometimes it was a button on the clothes, sometimes it was a small object in the background, and sometimes it was an unintentional graffiti, which could not be found at all if I did not compare it carefully, and I only carefully identified it after seeing Duan Jiaming's painting, and I found this as a result.

I asked Zhang Ziang: "Have you seen this symbol before?" ”

This is not a very complex symbol, the shape is an equilateral triangle, and the inside leads a line from one-third of the edge of each triangle to the adjacent side but does not want to intersect, and roughly two-thirds of the way it intersects with the line drawn from the adjacent side, and the length of the intersection is one-third of the line drawn out, so that the three sides repeat, so that the three intersecting lines form another triangle that does not look very regular inside the whole triangle. It forms a strong irregular contrast with the equilateral triangle on the outside, and at a glance, it looks like a kaleidoscope about to intersect.

Zhang Ziang was also shocked when he saw it, he looked at me with some surprise, but there was no shortage of glances, and finally I said: "This is the point, this strange symbol appeared in different times, and even accompanied by the occurrence of the whole case, so the question also came, Meng Guangwen was so dignified, why did he kill this person?" ”

In other words, Meng Guangwen must have some motive, if there is no motive, I don't believe it, after all, his adopted daughter became another unbelievable victim three years later.

As if I had thought of something, I asked Zhang Ziang: "Has a similar pattern appeared on the body of the butterfly corpse?" ”
