We soon came to the edge of the crack and continued to walk towards the hole, for it was the only way, but when we got there, we were stunned - how could the hole suddenly disappear? Could it be that the location is misremembered?

We searched several times but still couldn't find it.

Will it make people clogged?

We relied on our memory to find the location of the entrance to the cave several times, but we couldn't find it, and it was said that even if the entrance to the cave was blocked by stones, there should be traces, but we didn't find any clues.

And, for some reason, everyone found that all of us couldn't remember the specific location, and could only vaguely remember that the location of the cave entrance should be within one or two hundred meters of this vicinity.

Supposedly, even if the entrance to the cave is blocked, we can find the approximate location of the cave just by memory, because we have been here once, and it was only an hour or two ago, but for some reason, for the location of the cave, we suddenly found that all the people, as if they had lost their memory, only vaguely remembered, the hole should be in this area, as for the specific location, we can't remember, what is going on?

How could this happen? It's so weird!

At this time, for some reason, Crazy Six suddenly turned around and looked at each of us with a strange look, looking at our straight hair, is Crazy Six mentally abnormal?

My cousin was also surprised and asked, "Senior, what's wrong with you?" How can you stare at us with such eyes? ”

When my cousin asked, Madman Six seemed to realize that his behavior was a little strange, so he laughed at himself and said, "Ha, you don't have to be afraid, I'm fine, I just think it's very strange, we just came out of this hole, why can't we remember the location of the hole?" Don't you think that's weird? ”

Sister Li said quickly: "Yes, it's really weird, I don't think about it, I can't remember the location of the hole, I just think that it should be within these hundreds of meters, as for the more accurate location, but I can't remember it, if there is a person like this, maybe it's because of his ability to remember the direction, but there are so many of us, everyone doesn't remember, it's very incredible, but I can't find the location of the hole, you don't have to keep staring at us, we look at it in our hearts, Do you think you're not mentally normal? ”

After listening to Sister Li's words, Crazy Six laughed out loud: "Xiao Li is right, what weird things happen here, it can happen at any time, you think I'm not mentally normal, it's inevitable, ha, but the reason why I'm staring at you is to solve the mystery - that is, why can't we remember the mystery of the location of the cave entrance?" ”

Can we unravel this mystery? The more people listened, the more confused they became.

Maniac Six nodded, and spat out a sentence leisurely: "I seem to have figured it out." ”

Got it? All the people were stunned and didn't know what Crazy Six meant.

Madman Six then explained: "Have you noticed, when we first found the entrance to the cave, the stone blocking the entrance of the cave seemed to be very unusual, how unusual was it? Do you remember the kind of stone that made Xiao Lei and Hongmei lose their memory? ”

The cousin seemed to suddenly realize: "Are you saying that the stone that blocked the entrance of the cave is the same as the stone that made Xiao Lei and them lose their memory?" ”

Crazy Six nodded and said: "Yes, it can't be said that it is exactly the same, it can only be said that it is similar, and the effect is not as strong as the stone that Xiao Lei encountered before." ”

"No, the kind of stone we encountered before, when you look at it with a magnifying glass, that special gas can be emitted, and the guide person temporarily loses his memory, didn't the female assistant say this principle? But for the stone that blocked the entrance of the cave, we didn't use a magnifying glass to look at it, even if it was that kind of stone, without the concentrating effect of the magnifying glass, the gas in it would not be released. ”

The madman shook his head again and again and said: "The reason why that gas can be released is because the magnifying glass has the effect of concentrating light, and after the light is polymerized, it can excite that gas, which is true, but the gas that can make people temporarily lose their memory may also be released in another way."

For example, when you use a drill diamond head, the gas in it has been released, and each of us inhales that gas - although the gas is very weak - so we also have a temporary amnesia, this slight amnesia, we can't remember the specific location of the hole, but other things, we can remember more clearly. ”

If that's the case, plugging the entrance with the kind of stone that makes people lose their memory for a short time is really an ingenious design, that is, even if we find the hole and drill into it, we still can't remember the exact location of the hole, so that we can better ensure the secrecy of the hole, as if there is more insurance.

"Actually, when everyone entered the cave, I found that everyone's meridians seemed to have undergone a slight change, and the changed meridians were all related to memory, but I didn't particularly care about it at the time, thinking that it might be because everyone was nervous, but now it seems that it is not, it should be caused by the gas released by the stone, I just looked at everyone, just to see if everyone's meridians have been restored to normal."

For his strange behavior just now, Crazy Six also explained.

Now that we've found the cause of the amnesia, what do we do next? The extent of the hole that we can determine is about 1,200 meters -- that is, we know that the entrance to the cave should be within this 200 meters, but the exact location cannot be determined, and within this 200 meters we have searched for it many times, and like the first time, we have tried it with a scarf, but we have found nothing.

It's so weird! Is the clue that was finally found going to be broken again?

"Could it be those Japanese troublemakers, they are the best at doing this kind of thing, and it was after they blocked the road that we came here by mistake."

The madman said fiercely that as a person who had personally experienced the Anti-Japanese War, he had always hated the Japanese.

The cousin also nodded and said, "There is such a possibility, because the monster that the 'Monkey Eagle' is chasing seems to have something to do with the Japanese, and they are likely to be on the other side of the crack, so they sealed this hole in order not to let us know their secret." ”

Grandma Di, those half-human, half-ghost Japanese, are simply not things, but what do we do now? Since the entrance to the cave is blocked, we can't get to the other side, and the next step of the plan can't be carried out.

At this moment, Xiao Lei suddenly said: "By the way, I have a way, maybe I can find the hole again." ”

Xiao Lei's words made everyone's mood cheer up all of a sudden.

Xiao Lei continued: "They were able to block the hole so without showing any traces in a short period of time, and they couldn't find a single gap, they must have used a special substance, and that special substance covered up the gap, and this special substance, we have encountered it before, remember?"

It was unusual to follow the amphibious man to the edge of the cliff and see a pine tree, which was hollow and the entrance to a cave, and then we cut down the pine tree, but the second time we went, we couldn't find any trace of the pine tree, the ground was full of stones, and it was this special substance that covered the stump.

This substance is like cement, it is muddy when wet, but when exposed to air, it solidifies quickly, and the color and texture become the same as that of stone. ”

After Xiao Lei reminded us so much, we suddenly remembered that this is the case, indeed, the two techniques are too similar.

I, Hongmei, and the female translator are all people who have personally experienced that operation, and we still remember the situation at that time, so we told the other people in detail about the detailed situation at that time, and after everyone listened, they all completely agreed with Xiao Lei's speculation.

"Even if we understand what's going on, what's the use, can't we still find the location of the hole?" The female translator shook her head helplessly and said.

Xiao Lei smiled and said: "Not necessarily, after our operation, I was very interested in that substance, so I took some samples and went back to study it, because I think that kind of strange substance, in the military, may have a high use value, because it can seal a hole in a short period of time, and from the surface, there are no clues, which is very meaningful for camouflage in military operations."

After several experiments, I found that the substance is a little different from cement - after the cement hardens, even if it encounters water, it will not become muddy, but this substance is different, after it hardens, if it encounters water again, it will return to its original shape. ”

Hearing Xiao Lei say this, we are all excited, since we know this characteristic, we can find the location of the cave entrance, there is a way - within this 200 meters range, you can splash water on the stone wall, and after that substance encounters water, it will melt into mud again, so that you can easily find the location of the cave entrance.

Because we guessed that the entrance to the cave should have been partially blocked by a large stone, but the gap between the stone and the hole must have been covered with that substance, so as long as the gap was found, the location of the hole could be determined.

The water is easy to find, there is a stream a few meters away, Xiao Lei took out a few plastic bags from the bag, and then we used the plastic bags to get water from the stream, poured on the cave wall, and observed while pouring, so that it has been poured along the stone wall for more than ten meters, suddenly, Kenya shouted loudly: "Look, I found it, there is a small piece of 'stone' here that has melted and cracked, and the hole should be here." ”

Everyone hurriedly gathered around to look, and sure enough, there were pieces of 'stone' on the stone wall, which were slowly dissolving, turning into mud, and being washed down by the water, and at the same time, a clear gap appeared.

The hole has finally been found!

Xiao Lei did the same again, took out the sapper shovel, and pulled out the drill bit, and when he was about to diamond the head again, he suddenly stopped again: "When I drill, everyone hides away, and I also bring a gas mask myself, so that everyone will not be affected by that gas." “
