Fortunately, the water has eased.

This protective suit is completely waterproof for several people, and there is no threat to life for a while.

Even, a few people who were sent down by Zhou Long were happily diving into the water at this time.

Shen Chuan counted the number of people, and after making sure that his people were all right, he whispered: "Report the number, I'll come first, 1!" ”

“2、3、4……”

Shen Chuan's people have not decreased, but Yang Sen and the others are not comfortable.

The strong current, although it did not sweep them away, did not have the means to breathe underwater.

Even if you swim outside according to the tunnel you came down now.

You have to swim for a long time to get out.

The water that could fill the entire cave below is at least fifty meters deep.

Janssen did not have protective clothing, and the first wave of water had already injured them.

And the water pressure is also very high, let alone float up, even if they move their bodies, it is difficult for them.

"Mr. Shen, what about the following people?"

Lin Shuyao looked at a few people in the water and land.

Although she also knew that it was too virgin to say so.

But as a human being, seeing a few people die in front of him, with a little empathy, he still feels sorry in his heart.

"Zhou Long, you arrange a few people to send them up, during which let them take a few sips of the spare oxygen valve, after sending them up, it doesn't matter if they are dead or alive, Zhang Wei remembers to send someone down to escort the living people to the police station!"

After arranging those few wastes, Shen Chuan continued: "Lin Changsheng, you swim over a little!" ”

"Mr. Shen, what's the matter?"

"Come to me and see if there's a gap in the waterfall just now!"

I have to say that this current is really fierce.

The outer layer of Shen Chuan's helmet had some cracks due to the impact.

Fortunately, this helmet has two layers of protective glass, and even if the outer layer is broken, the inner layer can also play the same protective role.

You can think about it, if there is no protective clothing, it is estimated that the people will have to explain here.

However, the Feng Shui master may never have dreamed that a few hundred years later, he would meet a soft girl coin player, wearing a lot of top-notch equipment, and dug his grave!

Lin Changsheng swam over to take a closer look, and the flow of the waterfall had stopped, and the entire cave was submerged.

If you look closely, the location of the waterfall does have a crack more than ten meters wide.

It's just that the entire cave is filled.

Lin Changsheng wasn't sure if the waterfall was empty.

"Mr. Shen, there is indeed a gap!"

"Well, Lin Changsheng, look at the parchment roll, the shape of the line on it looks like an hourglass?"

If it is the same as Shen Chuan's guess, then the space in this mountain is in the shape of an hourglass.

Groundwater pools into the cavity above, due to tension, and probably the Feng Shui master has treated the mouth of the waterfall specially.

So, the water can only flow down a little slowly.

Once someone enters this underground cavity, they may be fine if they come in.

But if it causes too strong a vibration, such as a gunshot, moving, or jumping off the same way as before.

It is possible to break the tension of the waterfall gap.

As a result, all the water above poured down into the hollow below.

"That's right, Mr. Shen, the waterfall is the center point, and when this line converges, it is indeed like an hourglass!"

guessed correctly, Shen Chuan was also sure.

If the feng shui master really built a treasure place according to the treasure map, then the upper and lower spaces should be the same size.

Therefore, when the water above has completely flowed down, a cavity must form on the top.

Shen Chuan couldn't wait to swim over, followed by several other people.

The further upstream, the more oppressive the body felt lessened.

This is the feeling that comes from the change in water pressure.

Shen Chuan had learned to dive before, so he was still reminding a few people while swimming: "Our position just now is more than 50 meters underwater, don't be in a hurry upstream, swim slowly diagonally, otherwise there may be danger!" ”

The danger that Shen Chuan is talking about is hydrobarism.

The pressure at the bottom of the water is completely different from the outside.

Although, the body adapts to this pressure.

However, if the rate of rise is too fast and the pressure is decreasing, but the body does not adapt to it, an air embolism can form in the blood vessels and in the body.

For divers, an air embolism is even more dangerous than the absence of oxygen.

Countless divers die from air embolism every year.

With Shen Chuan's leadership, everyone slowly swam to the mouth of the waterfall.

Shen Chuan controlled his breathing, took two deep breaths, and after making sure that there was a problem, he grabbed the mouth of the waterfall and began to swim into the passage.

In the water, there is no way to distinguish between up and down and front and back.

You can only judge by experience.

Under the light of the flashlight, the crack in this waterfall is like a long abyss.

Since the flashlight does not shine brightly, and there is no luminous stone in this crack.

Therefore, the atmosphere of horror is much heavier than in the hollow below.

It's like a deepwater monster can appear at any moment.

Zhou Long didn't know if his brain was pumping, so he suddenly shook his wit and asked, "You say, with so much water, will there be a water monster?" ”

A few people only felt goosebumps all over their bodies.

In the dark waters, it is much more terrifying than a dark land.

I will unconsciously associate all kinds of terrifying pictures in my mind.

Coupled with Zhou Long's hint, everyone's heartbeat began to speed up.

Suddenly, it was as if a dark shadow had passed through the tunnel.

Shen Chuan hurriedly stopped, leaned on the stone next to him and said, "Don't swim forward, I really want to see something!" ”

Everyone can't tell the difference between up and down, left and right, so they can only stick on the stone next to them indiscriminately, look at Shen Chuan nervously, and ask, "Mr. Shen, what is this?" ”

"Zhang Wei, can you detect something on top of us?"

Shen Chuan shouted several times in a row, but did not get a reply from Zhang Wei.

I don't know if it's the water or the mountains.

Again, the situation is getting complicated.

Now, it is possible to swim more than 10 meters into the tunnel and swim out of the water.

It's also possible that you'll come across something you've never encountered before.

The choice was given to Shen Chuan.

Shen Chuan thought for a moment and made a decision in his heart.

"If you are afraid of danger, you can go back. Zhou Long, Xiaoyun, you come with me! ”

Except for Zhou Long Xiaoyun, Shen Chuan didn't want to order anyone and risked his life to follow him.

Not an order, to be precise.

He knew that even if he let Zhou Long Xiaoyun and the two go, these two would definitely not leave.

"Mr. Shen, don't be kidding, it's all here, no matter what it is, we have to go out together!" Lin Changsheng said with a smile.

A few of Zhou Long's subordinates next to him also chimed in: "Brother Shen Zonglong, no matter what, we will follow you!" ”
