After listening to this, the fat man said: "As soon as you say this, I understand, then how to carry out resistance training, let's learn and sell now, what are the chances of success?" ”

Zhang Tangrui smiled bitterly and said: "It's impossible to learn and sell now, when we trained before, there would be special people to check and start the experiment one by one with bells, but now we don't have bells on hand, if we go directly to underwater training, I don't even know how to die." After a pause, Zhang Tangrui said: "And this time something happened to our Zhang family, the time is very urgent, even if we have bells on hand, but it will take more than a month to train the most basic effect, and this effect is not enough to resist so many bells underwater." ”

I suddenly said, yes, I didn't say it.

The fat man hissed and said, "When you say that, don't you want us to roll up and go home?" In my opinion, since those broken bells are hallucinatory with our sense of hearing, let's just plug our ears when we go into the water. ”

I suddenly felt that this method was quite reliable, simple, and had no worries, so I couldn't help but give the fat man a thumbs up and said, "Fat man, the little one is served." The fat man's proud tail was cocked, and he said: "Fat man, I can fight tigers in the mountains, catch dragons in the sea, and my whole body is shining with wisdom, this little gadget is not a problem." ”

While the two of us were talking, Jinjing suddenly poured a basin of cold water and said, "Do you know how often sound travels underwater?" Don't you know that people have inner ears? ”

"In the ears?" The fat man said, "What is that?" ”

I was suddenly woken up by the basin of cold water in Jinjing, and I couldn't help but pat the fat man's shoulder with a wry smile, and said, "What we just thought was too simple. "I guess the fat man didn't understand it, so I explained it to him.

Most people should have had this experience at one time or another.

When I go to bed at night, there is a construction site around, or a guest at home plays cards all night, and the sound is noisy and it is difficult to sleep, so I will try to stuff cotton or other things into my ears to block the sound.

In fact, this does have a certain effect, but anyone who has done it must have had the experience that no matter how tightly you stuff it, the sound will not be completely cut off.

In this regard, there are two reasons, because the transmission of sound can penetrate the substance, which is why the music is played in a closed room, and the people outside can hear it.

Secondly, it is because there is an inner ear inside the outer ear.

There are many animals, especially aquatic creatures, they often only have an inner ear, but they are also very sensitive to hearing, and it is difficult for the human inner ear to isolate sound. In other words, even if we do stuff something, we can't completely block out the sound in the water.

Of course, there is a kind of diving equipment that can be achieved, but our current conditions do not allow it, and the time to prepare the equipment for round trips will take at least half a month, I have been waiting for two years, I can take my time, but Zhang Tangrui's gang obviously can't afford half a month.

After I finished speaking, Zhang Tangrui shook his head and said, "This is just one of the reasons, and there is another reason. ”

The fat man said: "What is the reason why you say it directly, when is this happening, and you are still selling Guanzi." ”

Zhang Tangrui said: "In addition to auditory hallucination, there is also a reason for hallucination, that is, psychological suggestion. I don't know if you have ever been in close contact with this kind of bell, on its surface, there is a pattern, which can produce a similar hypnotic effect, this effect, the more people who know the bell, the greater the effect, but the kind of unclear, such as people who don't know that the bell can be a hallucination, they look at it, but it will not have much impact, this pattern, coupled with people's sense of supervision, will produce hallucinatory psychological implications. ”

After he finished speaking, I immediately smiled bitterly and said, "Is there no other way?" ”

Zhang Tangrui didn't say anything, he squinted, gritted his teeth, and said, "If you can't do it, you can blast it underwater." "This time we came out, all kinds of weapons are not less, if we are caught, a sentence of ten years or eight years is not light, if it is not a little more powerful now, it is estimated that even how to get equipment to Inner Mongolia is a big deal.

I felt something was wrong and said, "If you can blast it underwater, will you not use it?" And can the water hole under it withstand the blasting? What if it all collapses? ”

In this way, a group of seven of us sat around to discuss, constantly put forward ideas, and finally vetoed them one by one, the fat man did not believe in evil, and said: "Innocent comrade, what kind of inner ear you just said, can receive limited hearing, just follow the old method, let's plug our ears, blindfold, and touch the bell hole first." ”

After the fat man finished speaking, the others did not say anything, and so far, it can only be like this, the eyes are blindfolded, although it is not safe underwater, but because there are hexagonal bells, there are no vicious fish under the water, and it should not be a big problem.

As for plugging the ears, the sound of the bell is bound to be much smaller, and it should also have a certain effect, thinking of this, I suddenly came up with a more bold guess, so I said to everyone: "The hexagonal bell relies on sound to affect the brain sound, if we change the scale of the sound, maybe we can avoid being confused." ”

"Change the scale?" Zhang Tangrui whispered and muttered: "Theoretically, the feasibility is very high, but how to change the scale?" Is there anything you can do? I said, "The sound of the hexagonal bell is natural, not acquired, and it is impossible to change it, but we can interfere with the brain to accept the sound of the hexagonal bell at the same time, and then accept other sounds, so that when several sounds are mixed together, the audio will change." ”

The fat man suddenly realized and said: "Let's take an MP3 into the water and put that nine-section whip, the two voices will definitely collide across the century." I corrected him again and said, "It's nunchucks, not nine-section whips." ”

The fat man touched his chin and said, "Naive, your idea is still very good, why don't we wait for you here, you hurry up, go back to Jungar, and buy us seven mp3s?" ”

At this time, Heshui smiled and said, "I brought one with me." ”

The fat man said: "What's the use of a top." ”

I said: "I don't mind going back and forth, although this road is hard, but for the sake of the little brother, it is not a problem to go up the knife mountain and down the sea of fire, even let me go back and forth ten times, I don't frown, but these few ......"

I looked at Zhang Tangrui, Zhang Tangrui's eyebrows furrowed, and he groaned for a long time, and said, "You don't need to buy that thing." Then he pointed to his mouth and said, "Use your own voice." I immediately understood, and then couldn't help but smile bitterly, and said, "Brother Zhang, you're playing with us, you mean, let's move forward while singing?" ”

Zhang Tangrui nodded.

The fat man said directly: "! ”

I didn't say anything, but I thought like a fat man.

After Lao Hu's incident, going into the water became a heart problem for me and the fat man, and the two almost unanimously began to refresh the underwater breath-holding record. The human brain will be brain dead if it does not receive fresh oxygen for six minutes, and the average normal person will lose his strength after holding his breath for three minutes at most, and the brain will be chaotic.

Before Ghost Thunder Mountain, my highest breath-holding record was only about one minute and forty seconds, and I died for two minutes. Later, because of Lao Hu's matter, I would bury myself in the water when I had nothing to do, but now I and the fat man can hold it for at least four minutes, which is already a great achievement for ordinary people.

It is said that the Guinness World Record can hold up to 17 minutes.

The fat man and I are just ordinary people, and we don't have the perverted training methods of the Zhang family, and four minutes is already our limit.

This time we didn't bring underwater equipment, but this waterway will not be very long because it extends into the belly of the mountain, and I am confident that we can swim naked without relying on equipment, but now, according to Zhang Tangrui, we not only hold our breath and go into the water, but also have to sing?

We are a group of seven people, if we wear gas masks and sing underwater at the same time, we can indeed achieve the same effect as mp3, but we are just ordinary people, I don't know if Zhang Tangrui and others can do it, but this kind of difficulty, I and the fat man are absolutely unavoidable.

Hold your breath for four minutes while singing?

Just kidding!

I said directly, "Our brothers are just ordinary people, it's okay to hold your breath, it's too difficult to sing, if you are really in such a hurry, you can go down by yourself, we bought diving equipment and then went into the water." "Anyway, what I have now is time, and I can't afford to take such a big risk and act with Zhang Tangrui and others.

After I finished speaking, Zhang Tangrui smiled and said, "Of course I didn't let you." He pointed to Heqing and said, "Their records are all at the Guinness level, which is not very difficult." ”

I looked at the three young faces and had some doubts in my heart, but since we had said that, we could not refuse, and after the group had finished their discussions, they began to gather their equipment, tie up the raft, and prepare to enter the water.

The last step before entering the water is to inhale and put on a gas mask.

It's worth mentioning this way, because I've never seen anyone inhale in this way.

I saw that the river water and others inhaled for a long time, and when they inhaled, their chests bulged, and the position of their abdomen kept squirming, as if all the air was stored in their stomachs, which was very peculiar.

It took about half a minute for the three of them to put their masks on their faces, and at the same time, we inhaled enough air and started to get into the water.

The underwater environment is very dark, and we were going to be blindfolded at first, but now we can save this step. As we had judged the house in advance, the rest went relatively well, and we soon reached the periphery of the cave, where there was a faint sound of bells, which was relatively small, but before we could hear it, there was a more muffled singing.

Both sounds are relatively small, and when they are mixed together, they completely change.
