He was reborn and became a firefighter again?

Chapter 422 The first battle, successful!

Where is the direction of this suction?

When Fang Huai felt it carefully, his sense of direction disappeared again.

I took out the air pressure gauge and looked at it. It was already less than 6 MPa and was about to sound the alarm.

Gotta go up.

He was not in a hurry, but he was afraid that the people on the shore would be. In this moment, the people above sent him feedback signals several times through the safety rope.

His breathing rate is much lower than that of ordinary people. Now his air breathing is only 6 MPa. He Zhijun and Lian Xu must have been up there for a while.

Unable to figure out the depth and orientation of this place, Fang Huai could only float vertically and slowly as much as possible.

The time to get out of the water is very long.

It took nearly 6 minutes to reach the water.

When a person quickly moves from a high-pressure place to a low-pressure place, the body will be like a bottle of carbonated drink that has been shaken. The liquid-containing tissues release a large amount of air, forming bubbles.

Such as blood vessels, lymphatic system, muscles, especially the arterial system, rapid flow of bubbles will lead to tissue ischemia, hypoxia and necrosis.

This is decompression sickness.

Therefore, the ascent process should not exceed 10 meters in one minute, and you should stay five meters underwater for three minutes to allow your body to adapt before you can go ashore.

In fact, Fang Huai felt that with his physical strength, he didn't have to do these skills so seriously, but he didn't feel anything unusual about this thing, so he didn't dare to gamble.

"Come out, come out!"

"breathe…"

He shook his ears and balanced the ear pressure again to force the water out. The surrounding sounds, including his own breathing, became clearer.

His position was actually more than twenty meters away from the rubber boat.

He swam to the kayak and once on board, He Zhijun shouted from the other kayak.

"Fang Huai, what did you find?"

Fang Huai took off his respirator, raised his hand to block the dazzling sunlight, sorted out his thoughts, and asked:

"What did you find there?"

He Zhijun shook his head.

Lian Xu raised his hand, held something between his fingers, and shook it.

"I found two rings, and one seems to be gold."

Fang Huai:......

You are here on a treasure hunt.

"Did you feel the vortex?"

Fang Huai shouted, and now the two people shook their heads in unison.

He felt a little disappointed in his heart, wondering if it was just his misunderstanding.

However, seeing a group of people standing anxiously watching on the shore, and thinking that this was the squadron's first outing for reinforcements, Fang Huai decided to give it a try.

He stood up and said loudly:

"Change your oxygen and rest for five minutes. Come here, the three of us will go look for the place where I came out of the water just now! Mainly look for the whirlpool! I felt the suction just now!"

"swirl?"

"You mean, the person was sucked?"

The conversation on the water caused a lot of commotion and discussion on the shore above.

Captain Li reminded loudly again: "The whirlpool is very dangerous! Pay attention to safety!"

Such a large water area gives underwater vortices a very large space to grow. Once a large vortex is formed, the suction force is quite amazing.

Fang Huai looked at the vast water and sighed: "No matter what, let's try it first! If you can't find it, this area is enough for us today! This person is down there. Since we are here, we must find it." Stay!"

He Zhijun and Lian Xu looked at each other and understood what Fang Huai meant.

"it is good!"

...

That's what it says.

The three of them visited three times but found no trace.

The small area that Fang Huai randomly designated was about the size of a foundation, only a few hundred square meters.

But when multiplied by a depth of thirty to forty meters, it becomes a three-dimensional water area of ​​tens of thousands of square meters and a huge tall building.

Below fifteen meters, the visible range of the diving light was only two or three meters, and there was no reference. They were not even sure whether they had reached the space that Fang Huai had just reached.

However, after a few times, everyone has a clear understanding of Fang Huai's endurance. Others can take care of him for 40 minutes with a can of gas, but he can take care of it for an hour!

The sun is in the sky, and the sky is getting hotter and hotter.

The families of the victims also came, and the cries became louder and louder.

"Our old Zhong won't be here! He could swim! He was just drunk and dizzy by you, so he didn't swim up! He must have swam far away and was washed down by the water! You... need to be responsible!"

The police conducted a day-long review of several receptionists and now informed the family members that it was determined that the victim went to the lake to urinate and accidentally fell into the water. The family members heard this and it seemed that the unit here was not prepared to take responsibility, so they started to make a fuss again. They made a big fuss about why they were drunk.

"My old Zhong can't be found now. What should we do if we are orphans and widowed... He listened to his work unit and came to work. Now he has lost his life here and no one can be found. Now no one comes to say a word in the provincial capital. Well, what should we do?”

"Sister-in-law, our superiors have informed us that we are fully cooperating. People from our unit are here, as well as people from the Xingyi government, fire department, and public security. We will definitely try our best to find him. Don't worry!"

There was a lot of noise on the shore.

Under the water, Fang Huai changed his headlamp and dived to the bottom again. He held a thin piece of oily paper in his hand. While swimming, he tore the paper into pieces, threw them around, and then looked around.

Only these scraps of paper can most keenly reflect the attraction around them.

Paper scraps float with tiny particles in the water.

When the stack of paper was almost finished, there was finally something unusual.

On the right side, some scraps of paper slowly rotated and moved closer to one place. A small handful of scraps actually traced a path.

found it!

Fang Huai quickly swam in that direction.

Soon, a clear direction of water flow could be discovered based only on the particles in the water.

It's becoming more and more obvious.

A rocky mountain gradually appeared in front of us, just like Sun Wukong entering the East China Sea and gradually discovering the Dragon Palace.

No wonder I can't find it. This location is not underneath at all, but on a rocky mountain seven or eight meters away from the river bed!

Fang Huai's eyes grew wider and wider, and his swimming movements slowly stopped, but he felt that the current was pulling him into a half-human-sized hole in the rocky mountain.

This is not a simple whirlpool, but a cave with water!

Moreover, the surrounding water flow shows that this cave has already formed a passage, but it is not clear where it leads.

This is too scary. If there is something hundreds of meters long, if it goes in and gets stuck anywhere, wouldn't it be buried inside?

Fang Huai quickly tightened the safety rope and moved further away.

The tug on the hand sent a signal, and the people above began to drag him hard. This time, he was dragged away.

Feeling that the rope protection was completely effective, he felt a sense of security. He looked at the air pressure of the cylinder and saw that it was still 15 MPa. He then pulled the rope three times to release a safety signal, relaxed the rope again, and boldly approached. , scratching the edge of the hole, probed, and took a look inside.

Just this one sight made him tremble with fear, and at the same time, he was ecstatic.
