Xiaohua gave me two strokes and told me his thoughts: "There are reliefs all around, and the iron plate can rotate, and the relief only has four directions, so even if you don't see this photo, it is easy to deduce the position in the photo by pushing the iron plate indiscriminately, if this is a secret hint, it is too easy to be tried, and there is no combination." ”

I frowned, still not quite understood, so he continued: "For example, the safe at our home will have at least three passwords to have the effect of a password, and a password bit will have zero to nine or ten possibilities, so the complexity of the password is enough." Whatever the disc was, if it was combined with the surrounding reliefs, the code, or anything that prevented someone from activating a mechanism quickly, then there were only four possibilities for it, and a three-year-old could easily try it out. He paused, "Then it's actually useless, for example, your safe has a one-digit password, and it can only be one from one to four, it's not a safe, because it's not safe at all." ”

I flicked the photo with my finger and immediately understood that he had a point.

Xiaohua continued: "Let's assume that the technology at that time could only make a lock with a one-digit password and only four digits from one to four to choose from one, how do you make this lock have a sufficient insurance effect? He looked at me, "Do you know the law of contraction?" ”

I shook my head, and Xiaohua's tone was very calm, as if she was telling someone an old artist about the play: "When you don't have enough things to choose from, reduce the number of choices you have." It's like defusing a bomb, when you only have three leads to cut, red, yellow, and blue, you can probably only cut it once at most, and if you cut it wrong, it will explode. So, if you're right, we're going to turn this iron plate, and it's likely that we're only going to have one chance. If you make a mistake, you're likely to activate the mechanism here, and you don't know what the consequences will be. ”

Saying that, he looked at the passage: "Before you are completely sure and prepared, you can't try it easily, there has already been a tragedy here, and it is likely to happen again." ”

I was a little stunned when I heard this, and I felt that I suddenly didn't know him: "Do you often solve problems in this tone?" ”

He shone a flashlight on the blood-soaked iron plate and said: "The criterion for doing things is to be rigorous, and this is how my family education has been since childhood. ”

Lao Jiumen Xie Jiuye is indeed known for doing things without leakage, I thought about it, what is the Wu family's standard for doing things? My grandfather seems to be famous for his popularity, which really doesn't sound like a long-faced thing now.

"Okay, Little Ninth Master, what should I do now." I sat down on the ground.

Xiaohua said: "We have to think from the beginning, everything has a reason, and there must be a strict necessity for such an elaborate mechanism set up here, let's think about it together, little third master." ”

Hearing this long-lost title, I don't know why my heart twitched, there was an inexplicable melancholy, he looked at me, I looked at him, and the two of them laughed. It seems that the two people are indeed saddled with a lot of similar things.

Both of them were silent, and I took out a packet of beef jerky from the food I brought, and said while eating: "You say, the descendants of Zhangjialou back then, how did they use the organs here?" Let's think about it like this, for example, if you are a descendant of the Zhang family, your father has passed away, and you want to bury your father in Zhangjialou in Guangxi, let's simulate the whole process. ”

Xiaohua said: "I must have burned him secretly, and then told them that he had already put him in, and the Xie family would not do anything superfluous." ”

I said, "Suppose it's the Zhang family, then what's the situation?" ”

Xiaohua thought for a while: "At the beginning, I will definitely get an explanation, the elders of the family will inform me about this in a secret place: we have a family tomb, I must bury my father in the tomb, but the tomb has very strict anti-theft measures, I must first go to Siguniang Mountain in Sichuan to find a cave, this cave can get the key to open the tomb." ”

"This doesn't make sense, if that's the case, he can't see the relief hint in Guangxi, he should have gone to Guangxi first, found the ancient tomb, and then found the relief tip, and then went to the cave here to find the key."

"Is the tip of that relief carving: Please take a photo here and take the photo to Siguniang Mountain in Sichuan?"

I didn't think it was funny at all, and I wanted to smile bitterly, but suddenly I was excited, and I thought of something.

"Photos? That's right, photos. ”

I immediately grabbed the photo sent by Guangxi, pinched it in my hand and sorted out my thoughts, and said in my heart that I would rely on it.

This is a very typical mistake of the ancestors, people will always take the details of the present reality as the basis for their own judgment, and ignore the various factors of time and place, we have always believed that the relief in Guangxi is actually a hint here, but, at that time, there is no photographic technology in the world.

So, in other words, it is impossible to have the situation where we are sitting here looking at the photos of Guangxi and pondering like we are now, and what they can convey is at most a copy or simply their own memory. Whether it's copying or memorizing, there will always be a loss of detail.

In particular, copying is likely to spread to the people, and it is very unsafe to convey any information by copying. As an anti-theft measure, an ancient tomb with such a complex is unlikely to make such a mistake. And how to ensure that future generations will go to the tomb with sketching tools? Could it be that all the members of the Zhang family were trained in sketching skills and techniques from an early age, and at the same time, there was a family rule that they must carry a full set of painting tools when they were buried?

Then, what is conveyed in this photo will not be as simple as the picture, and the meaning contained in it should be out of the picture, for example, when the Zhang family saw this relief, it is likely that they will suddenly realize and know the secret in this relief. It's like the cartoon "The sheep is dead below", when others see the picture, the target is only two pigeons and a dead sheep, but those who know the strange thing will immediately understand the cattleness in this painting.

It's useless to pay attention to the photo, understand the meaning of the image in the photo.
