Live Wilderness Adventure

Dolphin Bay is surrounded by mountains on three sides and faces the sea on one side, and it goes from gentle to deep. Before leaving the mountains on both sides, it looks like a small lake.

After leaving the mouth of the bay, the depth of Dolphin Bay will suddenly increase to hundreds of meters.

Although dolphins are good at diving, hundreds of meters are no problem, and their active range is mainly concentrated in the shallow sea between 30 meters and 50 meters.

Therefore, Bi Fang and Mandy's mission range is between ten meters and eighty meters. If they expand a circle, they can basically completely capture the behavior of dolphins.

It might sound like a lot to install more than twenty cameras, but it's not an easy job.

The radio has a huge loss in the medium, so the signal drops very quickly.

Dielectric loss in water, above 30KHz, 7500dB/km, 20 meters can attenuate 150dB, even if there is a base station on the water, there will be no signal below 20 meters.

The cameras used by Bi Fang and others this time are all automatic shooting, and they will be recycled after everything is over, and the shooting content will be taken out.

Therefore, the underwater installation is completely different from the previous mountain cameras. It is impossible to observe whether the position is right or not. The previous installation of the camera position can also be adjusted continuously through remote command, but now there is no such opportunity.

In view of the impending start of the dolphin fishing season, the difficulty of underwater installation will exponentially increase. It is impossible to repeatedly install and debug, and only one success can be pursued.

Among them, Bi Fang and Mandy must control the degree by themselves.

Fortunately, before that, both of them had a lot of shooting training with the help of camera assistant Mond, and they were barely half-professional photographers.

After installing the three cameras at a depth of ten meters in the shallow sea, Bi Fang, Bi Fang and Mandy continued to think about getting closer.

Twenty meters away, thirty meters away, the limit of active sinking has been reached, the world is pitch black and silent, and Bi Fang can clearly hear the beating of his heart.

Running to the animal sounds that automatically popped up in your mind, this may be the only signal that you can feel that you are still alive.

Bi Fangmo counted his heartbeat. When it was just like water, his heart rate was still 60-70 beats per minute, but now it has dropped to 30-40 beats per minute, more than doubled.

The special breathing method can fill Bi Fang's lungs with ten liters of air, bringing huge upward force, allowing him to float in the water without doing anything, reducing the amount of muscle movement against gravity.

The further down, the more the water pressure squeezed the lungs. At this time, Bi Fang and Mandy were both floating in the water relying on the air in their lungs.

At the same time, the diving reflex will cause the peripheral blood vessels to constrict, and the blood will leave the limbs and flow to the most important organs, the lungs, heart and brain.

And because of the huge amount of oxygen brought by the blood to the brain, as long as nitrogen intoxication does not occur, the diver's brain will be very clear at this time.

The more awake, the more I can feel that I have come to another world.

Silence, darkness.

Some people say that people don't know half as much about the ocean as they do about the moon.

This is not an exaggeration, because even in 1977, people had already sent astronauts to the moon, but it was naive to think that there were no active life forms in the ocean abyss below 6,000 meters.

There was an indescribable pressure in all directions, and every time I breathed through the breathing valve to expand my chest, it was like an oversized grip push.

As if he was firmly held by the giant and squeezed hard.

The equipment brought down by the first wave has been installed. Bi Fang and Mandy are separated by a distance of seven or eight meters. Press the flashlight switch and flash a few times. After confirming that everything is completed, prepare to go up and take the camera first.

Mandy nodded, stepped on the duck web, took a deep breath, and was about to float up when suddenly, a violent light flashed in front of Mandy.

That was Bi Fang pressing the flashlight, and it was very fast.

Emergency signal!

Mandy's mind was emptied of his thoughts. He was trained strictly without any hesitation. He only twisted the direction by instinct, but it was still a step too late!

The violently churning water stream was like a waterspout, and the volume slammed into Mandy's forehead with an irresistible impact.

In an instant, Mandy's eyes turned white, and water poured in from between his teeth and nostrils. The genuine seawater had a bitter and salty taste.

It's a pity that Mandy can't feel it anymore. Under the violent impact, his consciousness has been suddenly suspended, and he is directly drowning!

Before his consciousness died out, he could only see a huge ghost head, a sharp mouth full of fangs, a high bulging forehead, and protruding eyeballs!

No one expected the sudden change. Bi Fang took out the whaling fork from his waist and swam quickly towards Mandy.

A huge black shadow swam beside the two of them at an extremely fast speed, and the churning water could even roll up Mandy, who was drowning and fainted a few meters away.

Bi Fang's flashlight couldn't see its figure at all, it was like a ghost, wandering around the two of them.

Shark induction is indeed powerful, but it can only identify the basic size and existence of creatures, and cannot scan the shape of the creature accurately like a radar.

It was so fast that it almost hit Mandy before Bi Fang could react.

Bi Fang swam to Mandy's side, quickly put the breathing valve on him again, and it was stuck tightly.

At this time, Mandy's lungs had already been filled with sea water. Bi Fang came behind him and used the Heimlich maneuver, squeezing Mandy's lungs violently.

At this moment, the lingering ghost reappeared within Bi Fang's perception range, attacking rapidly!

It's a pity that Bi Fang is not Mandy. He can't see it in time. He can also clearly sense the arrival of the creature and respond in advance.

Bi Fang dragged Mandy, kicked on the rock wall, and quickly left the position.

The violent water flowed across his forehead, and the pressure formed almost pulled Bi Fang back to his original position. He wanted to swing a knife to attack, but the opponent's speed was so fast that he didn't stab him at all.

Bi Fang glanced down and took this opportunity to finally see part of the "ghost"!

GT!

Also called Niugang trevally!

An incomparably huge bullock trevally!

Bi Fang was slightly startled, and firmly held the whaling fork in his hand. Niugang trevally is the largest carnivorous fish in the trevally family, and can leap out of the water to prey on seabirds.

The guy in front of him is at least 1.6 meters long! Weighing over seventy kilograms!

A one-meter-six GT can prey on sharks!

Niugang trevally, the bison in the sea, is a powerful aquatic beast with a steep head and a powerful tail as its main features.

The habitat depth is between 2-80 meters. It is a large near-coastal migratory fish. It is distributed from the west of South Africa to the east of Hawaii, including northern Japan and southern Australia.

Often found in estuarine areas, feeding mainly at night.

It is greedy, strong, and no other creatures can threaten it except sharks and humans.

With a muscular torso and oversized paddle-shaped pectoral and caudal fins, he possesses real strength, explosive power, and incredible endurance.

The speed in the water can be as high as 60 kilometers per hour, and the human limit record can not even reach 40.

And the Niugang trevally is ferocious by nature, it will catch all the small fish it encounters in the sea area, and even catch the birds and hatchlings that stay on the sea surface.

When the Niugang trevally finds its prey, it will slam the prey violently to make it faint or swallow the prey in one bite.

The most terrifying thing is that the Niugang trevally often hunts in groups, so the predation is very fierce. It often happens that the adult Niugang trevally swallows the young Niugang trevally.

Is this guy crazy?

How dare you attack humans?

Niugang trevally has an extremely ferocious temperament, but not to this extent, right?

The 70-kilogram Niugang trevally is already at the same level as humans in terms of weight, and it is not common to attack animals of the same level. It is only possible when food is scarce.

and many more.

Is it because of the upcoming dolphin fishing season?

Bi Fang guessed this possibility. The arrival of the dolphins caused the nearby Niugang trevally to fall into a state of temporary food shortage.

So, is there really a lack of food?

Bi Fang calmed his heartbeat and tried his best to perceive the surrounding environment. Fortunately, there seemed to be this Niugang trevally nearby.

I don't know when I came to Dolphin Bay, bumped into Bi Fang and Mandy who were installing cameras, and even took the initiative to attack!

The huge impact force directly knocked the unexpected Mandy unconscious. This is because Bi Fang reminded him in time. If he hadn't subconsciously twisted his body, it might not have hit the hard forehead, but the fragile back of the head.

At that time, it will not be as simple as fainting, but it may be killed on the spot!

Not anymore.

Bi Fang took time to look at Mandy, who had fainted. A huge wound appeared on Mandy's forehead, with blood flowing out.

The bull terrier hovering nearby was ready to launch a deadly attack at any time. Bi Fang clung to Mandy with both hands, adjusted the oxygen pressure, drove it to the maximum, and squeezed his lungs again.

A large amount of seawater overflowed from Mandy's mouth, Bi Fang quickly tightened the breathing valve, and a large amount of oxygen escaped and poured into Mandy's lungs.

The second time, the third time.

I am afraid that Mandy never thought in his life that he, as a diving champion, would actually drown~www.readwn.com~ and was even rescued and drowning in the sea.

The fourth time, the long-awaited Niugang trevally attacked again!

Bi Fang quickly dodged, but holding the heavy Mandy, he was inconvenient to move at all. When he turned around briefly, he was hit by his arm.

In an instant, Bi Fang even had the illusion that his arm was broken, and the blood was instantly cut off in his arm.

Swelling, numbness, pain.

Wave after wave of strange feelings hit my heart.

Even the harpoon in his hand almost fell to the bottom of the sea.

Bi Fang could keenly feel that under the impact of his right arm, a large number of capillaries were broken, and the blood quickly accumulated under the skin.

He tried to clench the dagger again, but it was as if his arm was pressed in a nap, and when he woke up, it was painful and numb, and he couldn't hold it at all.

No wonder this guy is called the Water Bison.

Really powerful!

Keke on the shore was completely unaware of what was happening in the water. He hid in the dark, daring not to make the slightest sound and light, and carefully peeped around to make sure that no one came to find out what they did.

The lighthouse not far away still scans the sea monotonously.
