The depth of 52.7 meters is quite terrifying for ordinary people, because most people who have not received diving training are at most 10 meters, and if they are professional, about 30 meters, at this depth, they have to be at the sports level. Pen & Fun & Pavilion www.biquge.info

For example, the one in India dived more than 300 meters, which is a Guinness record, and it is not something we can do.

Most people can't dive into this depth at one time, and the reason why we can do it is because we have had adaptive dives before, not to mention Ah Zi and the others, who can carry out this mission are not ordinary people.

But sixteen minutes made my heart beat like thunder.

In fact, professional scuba oxygen cylinders can generally provide people with about an hour of diving, but this utilization rate is proportional to the depth of the dive, and we have about half an hour from the time we enter the water to the present.

Scuba is not pure oxygen, we use helium oxygen diving, which is a relatively safe one, but even so, the longer we stay underwater, the more dangerous we are, and at any time under the water pressure of the deep sea, rapid lesions of various organs may occur.

That is, we have less than sixteen minutes to live, and we must reach the surface of the water in sixteen minutes.

That's just too difficult for the environment we're in right now. I lay on my stomach, feeling a little hopeless.

At this moment, due to the angle, my face is forward, so the diving searchlight above my head also hit straight to the front of the water hole, and at this moment, I suddenly found that the water hole is different from the outside, and the surrounding area is quite smooth, as if there is a flow of water washed out for many years, and it seems to have been carved by human hands.

But if it was from a human hand, it must have been many years ago, and at that time, people did not have the current diving equipment, how could they dive to such a depth? A few thoughts quickly swirled through my mind, and finally I gritted my teeth and began to crawl forward.

Anyway, there is so little time left, so I just fight.

Zhou Xuanye in the back saw me suddenly crawling forward, and grabbed my feet with some puzzlement, I raised my hand and made a posture to follow.

However, the more I crawled, the more I felt that something was wrong with my body, and my whole body seemed to suddenly relax, and the blood all over my body was pressed like a flood that opened the floodgates, and this rush brought not relaxation, but a series of abnormal conditions such as arrhythmia, numbness in my hands and feet, etc.

How so?

During the month we were on the ship, it was not a mess every day, and Ah Zi and others on the ship had explanations about our deep-sea diving, so I realized that my current situation was very similar to diving sickness.

The so-called diving disease, also known as water sickness, is generally a series of symptoms caused by the sudden difference between the water pressure in the sea and the sea surface pressure when the diver is out of the water. This symptom often varies from one person to another, some people feel uncomfortable, and some people may even die suddenly.

But in any case, this disease often appears suddenly when it comes out of the water, so how can I have this reaction now?

Could this waterway ......

Thinking about it like this, I couldn't help but pause in my crawling movements, but as soon as I stopped, Zhou Xuanye, who had stopped me, actually began to push me forward.

I turned my head and didn't understand what was going on, but he only gave me a gesture to keep going.

Listening to Zhou Xuanye's words, it is generally true, I can only start self-regulation according to the breathing method taught by Ah Zi, this method is quite effective, although the feeling has not disappeared, but at least it has not aggravated.

The further I climbed, the more I felt that I had made the right decision, so after about 20 meters of crawling, I realized that I had my head out of the water

Of course, it's not that I've climbed out of here, but that the inside of the hole is a T-shape, with the middle point being where I came out of the water, with the entrance to the strait where I climbed on one side and the same seawater that runs diagonally on the other.

The third longest passage near them is inclined upwards, so that the sea water forms a very peculiar scene here, and instead of filling the hole, it creates an additional channel that is completely devoid of water.

It's incredible.

Moreover, by the change in water pressure, it can be determined that there must be air in it

I tentatively turned off the oxygen supply, put down the hood, and tried to breathe, but there was a terrible smell, the air quality was not very good, but it was not at the level of poisonous gas. For a while, I didn't care about thinking about why, so I hurriedly climbed up, and at this time, Zhou Xuanye and others also climbed up this wet but no seawater channel.

The three of them just came out of the water, their bodies were a little uncomfortable, they all lay on the ground panting, and after more than ten minutes, Tan Jian took the lead in getting up, slapped me directly on the back of the head, and said, "Idiot, why don't you run if you let you run." ”

I said righteously: "Am I the kind of person who leaves my brother and runs for my life?" "After that, I feel great. But Tan Jian's next sentence immediately poured cold water on me, and he said, "Don't you know that you will go up and get a rope first and then come to save people?" If you hadn't lost your strength halfway, I would have been able to take him to support him in the sea for a while longer, and I could have waited for rescue. ”

I was stunned, thought about the situation, and was speechless.

Tan Jian looked at me with disgust, not to mention how disgusted, he said: "Why can't you learn from Tang Linlin, look at how shrewd she is." ”

I remembered that Tang Linlin was spinning around in place at that time, and then quickly swam away, and said no, could it be that the girl was planning to get the rope?

Zhou Xuanye persuaded at this time and said: "Senior brother, forget it, Tiangu is also a good intention, you don't know if he is stupid, so don't always mention it." They are young and have a lot of self-esteem. ”

"...... "I'm so angry that I almost vomit blood, is this persuasion, this is completely scolding me in a different way." Under the grievance, I said; "If I knew this, I wouldn't have gone back to save you at that time, and let you drown at the bottom of the sea. Don't forget who dragged you just now, without me, you would have gone to the eye of the sea. ”

Zhou Xuanye is still the same as the previous Zhou Xuanye, and now this one, with the personality of Zhou Laoer, there seems to be no change on the surface, but there is too much black water in the stomach.

Zhou Xuanye smiled when he heard this, with a look of ill will in his eyes, and he said, "Let's make a bet." ”

The conversation became a little quicker, I said; "Bet? What to bet on? ”

He said, "Just bet on where this road leads." ”

I was shocked, knowing that this girl couldn't casually make such a bet, and I couldn't help but wonder, didn't this fox guess something?

Curious, I said; "Don't gamble, I don't have the money to bet with you. What the hell do you see, say it quickly, don't sell it. ”

Zhou Xuanye showed emotion on his face when he heard this, and said: "People are really fickle, you didn't talk to me like this before, you have always been very respectful and polite to me, how did you become like this now." After speaking, he showed a sad look of his son growing up and not recognizing his father.

"I respect Zhou Xuanye, not you."

He was surprised: "Am I not Zhou Xuanye?" Do I want to show you my ID card? ”

I sneered, and just as I was about to speak, Tan Jian frowned and said, "You two are singing double reeds?" Then he turned his head and asked Zhou Xuanye, saying;" What the hell is going on? ”

Zhou Xuanye straightened his expression and said: "When I climbed here, I kept calculating the distance, we were crawling towards the west of the strait, this direction is very close to the ghost stone pillar, and there is air here, in this sea area, the only thing that has the opportunity to contact the air is the ghost island that surfaces to the sea every night." It's night, at low tide, so I can be sure that this waterway definitely leads to the ghost pillar, and besides, we can borrow this way to get out. ”

I immediately drew the surrounding charts in my mind, and found that Zhou Xuanye's brain was too fast, and the ghost stone pillar was indeed the only possibility.

In this way, it is not strange how those ancient ancestors dug such a water hole at a depth of more than 50 meters at the bottom of the sea, because they built it from above.

Q: What puzzled me was, what were they building this passage for?

Thinking so, I asked.

Zhou Xuanye smiled and said, "I'm not an immortal, how can I know everything, go forward and see if you understand?" ”

The position we are in at the moment is tilted, the arc of the slope is not high, but it is very wet, but the space is much larger, at least people can sit up in it. Zhou Xuanye's physical strength was still a little weak, so Tan Jian took the lead in opening the way in front, and the three of us got on all fours and began to climb up.

ps: The third is hotter, please continue to vote for Su Tiangu's adventure team.
