After half an hour, maybe forty or fifty minutes, the wall door just now finally opened again, and Shen Jianqing walked back with a silver tray with an ugly face and put the tray in front of me.

Looking at the angry expression on his face, I think he probably wanted to slam something in front of me, but he was afraid of breaking it, so he didn't dare.

I looked down and the canister was open.

However, only half of it was opened.

Because there's a little cipher barrel in there.

There is a small cylinder inside the large cylinder, which is a container for double protection.

I didn't expect it.

When I reached out to pick it up again, I couldn't help but smile, deeply admiring the Xiujia's skill and thoroughness.

That's right, the puzzle is very unsafe protection, no matter whose hands this thing falls into, as long as that person's eyes are bright enough and his brain is smart enough, and he spends a little more thought and time, he can spell it out, so dangerous, it's not the Xiu's style of acting.

I took it in my hand and looked carefully, although the smaller password cylinder is the same material as the outside, but the password mode is completely different things, because it is not engraved with lines, but neat symbols, and all kinds of symbols are engraved all over the surface, some are familiar, some are raw, and some are familiar. Moreover, it is not a trap on the central axis, as in the outside one, but a small square grid, densely covered with the whole cylinder, and those symbols of unknown meaning are engraved on these grids.

These slots should be cipher disks.

The most familiar among the various symbols is the sickle-shaped pattern, which is the hidden pattern on Xiao Hai's neck and Peng Liang and Yin Saburo's arms, the generational marks of the Xiu family and the Yin family.

Then the moon, the stars, and the stones, all of which I had seen, on the inside of the bracelet on my left wrist and in the splint at the bottom of the box I had seen at Xiaohai's house earlier.

It used to be a puzzle password, but now it's a symbol password, double protection, and it is possible to solve it only if you have to be in the game.

I shook my head at Shen Jianqing with a blank face, saying that I really didn't know that this would happen, and I really didn't know how to solve it, so I was very helpless.

He looked at me coldly a few times, and felt that I didn't look like a showman, so he walked out with the code canister, and before going out, he ordered the two soldiers to watch me closely, and deliberately shouted a loud order: "If you dare to mess around, shoot directly!" ”

Look at his smugness, what if he really shoots? I don't believe it, with the particularity of my body, you can still shoot me to death!

Then I don't know how long I waited, he came back, followed by several people, among them was Yin Saburo, the cipher cylinder was in his hand, and he had obviously studied it. He wore a white shirt with three buttons open, and he didn't squint at me, asking me if I knew the meaning of the symbols on the cipher tube.

I shook my head, "I don't know." ”

He held the password barrel in front of me and said, "The password is four symbols, after it is solved, you can press it in order and in turn, and you can start again if you press the wrong one, it will not be damaged, and there is no limit to the number of times the password can be entered incorrectly." The self-destruct mechanism inside only works when violently dismantled. ”

The people of the Xiu family set up organs, the people of the Yin family studied the way to crack it, the Xiu family built a tomb, and the Yin family robbed the tomb, these two families have been married for generations, which is really interesting.

Yin Saburo said, picked up a handful of delicate silver tweezers from the full tray of tools held by the staff next to him, and showed me a demonstration, casually pressed into four squares with symbols, the password cylinder did not move at all, and then pressed one, and the four that were pressed in before all popped out, so the correct password can only be four symbols, if these are in line with the representative numbers, it is a four-digit number.

A light lit up in my heart, as if I knew what the four digits were.

If I'm not mistaken, it's 1937.

Yin Saburo said before that if it is a number, it must be a number that they feel is of great significance and can be associated with the clansmen or descendants. Uncle Xiu used 1937 here as a code to commemorate the tragic massacre, which has the same meaning as the mirror number signed by Xia Dongyi in all his paintings, for the sake of the past that cannot be forgotten.

The problem is that there are so many symbols, which symbol represents which number, it is difficult to deduce for a while.

But it's not impossible.

I asked Shen Jianqing if there were any symbols like this in the underground tombs of Chenjiawu.

He nodded, turned his face to look to the side, and Yin Saburo went out with his people, meaning that his mission here was complete.

As soon as Yin Saburo left, a stranger stumbled in from the outside, glasses as thick as beer bottles, pale face, and an old pedantic smell exuding from his body, holding a pile of materials in his arms, probably an expert in semiotics.

Really.

The expert put the information in his arms on the table, took out some photos and spread them out in front of me, all of them were taken from the tomb of Chenjiawu, and the end of each sarcophagus was engraved with this symbol on the code cylinder, because of the poor light, the photo was very blurry, but it did not affect the identification.

The semiotics expert told me in great detail about the study of these symbols, and at first a professor of archaeology suggested that it might be a decoration that expressed wishes for good luck and a good future and a stable future, carved on a sarcophagus, similar to a modern window grille. Several experts in semiotics and paleography disagreed, but for a time there was no better explanation. Later, after it was confirmed that the place was not a tomb but a laboratory, some people suggested that it was a number, which was used to mark the order of the sarcophagus in the tomb, but no matter how it was arranged, no one could find a pattern, and no one could crack it through various channels for help. After a few turnovers, they eventually preferred the term "conventional digital code".

The so-called "conventional number code" is a popular term, which means that it refers to a completely self-created, no rules to follow, and only based on convention and memory to use. For example, a few of us here sit down and discuss, the circle represents 1, the triangle represents 2, the pentagonal shape represents 3, the diamond represents 4, and the square represents 5...... And so on, there is no pattern, it is only up to us to agree and remember. Then it can be used in combination with two or three figures, for example, a circle plus a triangle represents 12, a diamond and a pentagonal shape represent 43, and it can also be combined with three or four.

I immediately knew and decided that they were right, and that the symbols on the sarcophagus and the cipher cylinder were conventional numeric codes.

And I immediately had a way to reason about them.

However, the expert said that they analyzed countless substitution methods against the order of the symbols and sarcophagus, and the conclusion did not work, because no matter how they were arranged, they were neither in the order of one, two, three, four, five, six, seven, eighty, ninety, nor in the order of nineteen, eight, seven, six, five, four, three, two, one, that is, there was no law to follow, so unless it was the insider at the time of the appointment, or the insider left a clue, there was no way to crack it.

I asked him if there were any other places or documents where such symbols appeared in the underground tombs of Chenjiawu.

He pushed his glasses, looked up at Shen Jianqing, and saw Shen Jianqing nodding, so he turned his face and said to me: "There is a chaotic diary in the relics of Chen Qiaobin, the murderer of the Chenjiawu serial murder four years ago, and there are several such symbols in it, but it has no effect on cracking it. ”

My heart was stirring.

When Li Xu told us about the murder of Chen Jiawu four years ago, he mentioned Chen Qiaobin's relics, some highly professional books on advanced mathematics, geometry, anatomy, philosophy, religion, and architecture, a diary of confusion, and scattered notes and the like, I wanted to see it at that time, but because they were all in the physical evidence room of the research center, it was impossible to show them to me, and I only glanced at a few photos, but I didn't see any flowers, so now is just an opportunity.

Chen Qiaobin was also a person in the incident, his father Chen Zuquan played the role of a contact point in Chenjiawu Village, and he was too lazy to go to Uncle Chen several times to pass on information through him, and I have reason to think that Chen Qiaobin also has some information related to the "Huan" organization in his hands.

Maybe it's hidden in his relics.

Now is a great, perhaps a unique opportunity, to be seized.

I looked at the expert in front of me and calmly offered to see Chen Qiaobin's relics, my tone was very light, and I couldn't make Shen Jianqing feel that I wanted to see it.

The expert turned his face to look at Shen Jianqing again, this time Shen Jianqing did not nod, the expert was helpless, so he had to change the topic lightly and said: "We have done a lot of searching and research, these symbols only appear in the underground tomb of Chenjiawu and Chen Qiaobin's diary, and there is no other place, it can be temporarily believed that they are the special numerical codes used by the person who conducted the human experiment in the tomb, for the purpose of recording various data and conditions of the experimental subject, A special symbology system designed to ensure that even if the data is leaked, it cannot be read by others. Since there is no record of the relevant experiments so far, even if the meaning of the symbol is deciphered, it is not very useful, and there is no need to spend so much time and effort. ”

I grinned expressionlessly, and pointed to the cipher cylinder on the table: "It's very useful now, and to open it, you have to decipher the meaning of these symbols." ”

The expert hadn't looked at the cipher cylinder carefully before, but only noticed the importance of the thing after I reminded him, so he carefully picked it up and looked at it carefully with his eyes, turned around to look at it, and sighed stainedly, saying that it was the first time he had seen these symbols on something other than Chenjiawu.

I said, "No, this thing also came out of Chenjiawu." ”

He was surprised, and his eyes showed the scientist's thirst for knowledge, and he hoped to crack the code, but because he didn't have the authority to meet my request, he turned his head to look at Shen Jianqing helplessly.

I also looked at Shen Jianqing and calmly asked to see Chen Qiaobin's relics again.

I sneered in my heart, no matter whether it is meaningful or not, I still have to watch it today, who let you ask me, who let you not have me, none of you can open this cipher tube!

I'm really going to carry it with you, see who is tough.
