Underwater, bubbles keep rising.

The bottom of the sea was pitch black, the light of the flashlight could only penetrate less than 6 meters in the seawater, and the silence was terrible, without any sound.

The sound of the wind, the sound of the water, all of them, the only thing that exists is the sound of their own heartbeat.

Bi Fang's teeth clenched the breathing valve, raising his perception to the highest level, spreading to fifteen meters, and the cow harbor trevally wandered and flickered in the circular field, occasionally breaking into the range of ten meters, which could make Bi Fang break out in a cold sweat.

Whenever Bi Fang dragged Mandy to the surface, the Ox Harbor Trevally would attack, knocking Bi Fang and Mandy to the bottom.

This is an extremely fierce hunter, but quite cunning.

Bi Fang exhaled slowly, slowly leaned back, leaned against the rock wall, and silently removed the flashlight above his and Mandy's heads.

He cut the fishing net used to hold the camera equipment and tied it to himself and Mandy to secure their bodies, then removed the oxygen cylinder from his body, took a deep breath of oxygen, tightened the valve of the oxygen cylinder, wound the two flashlights together, and tied the oxygen cylinder to the body with a snorkel.

The heart is pounding.

Bi Fang's body temperature was rising rapidly, and he could no longer feel the chill of the sea at this time.

He held his breath to make sure the flashlight was securely fastened, and then slowly unscrewed the valve port.

Slowly stepping on the rock wall, Bi Fang climbed up little by little with his strength, and seeing that he had a tendency to escape, the Niugang trevally really launched a charge again.

Bi Fang, who had been waiting for a long time, suddenly ripped open the valve in his hand and dragged Mandy up the wall!

Rocks were trampled onto rock walls, large swaths of fragile sandstone were crushed by trevally, and large clouds of sand and dust were stirred up in the sea.

In the midst of the chaos, the oxygen cylinder that was unscrewed quickly spewed out a stream of air, with a glowing flashlight, drawing a white wave mark in the depths of the ocean, and quickly shooting away into the distance.

What's even more incredible is that at the moment when the flashlight flew out, the Niugang trevally turned around and rushed in the direction of the flashlight!

Undoubtedly, this is a good time to escape!

Bi Fang pulled Mandy and went up with all his strength while the Niugang trevally chased after the flashlight.

A minute later, when the lighthouse's pillar of light swept across Dolphin Bay again, Bi Fang jerked out of the water, his strong arms splitting the waves and swimming towards the shore.

Keko, who was on the shore, noticed the movement and swam swiftly towards Bi Fang like water, and the two met in the water.

Keko was surprised by Mandy's coma: "What happened? ”

Bi Fang spat out a mouthful of seawater, panting, and his voice was hoarse: "Go ashore first." ”

With one more person to help, Bi Fang instantly felt much more relaxed, and the two of them worked together to drag Mandy towards the shore.

When he was able to step on the sand and gravel under his feet, Bi Fang was completely relieved, and fell on his back on the sand and coughed hard.

He also choked a lot of water when he was hit by the Cow Harbour trevally just underwater.

Mandy was dragged by Keko, leaving long trails in the sand.

He pulled Mandy's wetsuit open and began CPR.

They are all good divers, and they are all familiar with how to deal with drowning, and with Bi Fang's foundation, in less than half a minute, a large amount of seawater overflowed from Mandy's mouth and nose, and finally woke up suddenly.

Mandy sat up abruptly, coughing frantically after spitting out a mouthful of seawater.

Keko sat down on the beach, looked at Bi Fang, and said with difficulty: "What happened?" ”

Mandy coughed for a long time, and finally came to his senses, he looked around in confusion, his head ached, and suddenly remembered the scene before he fell unconscious, a grimace suddenly rushed towards him from the darkness, and the next moment, Mandy couldn't remember anything.

Bi Fang sat up from the ground and breathed a long sigh of relief: "A cow trevally." ”

"Cow trevally?"

Mandy and Queko were stunned at the same time.

The former corresponded to the image of the trevally with the grimace in his memory, and suddenly realized, reached out to touch his head, and quickly withdrew his fingers under the severe pain.

"Damn, it's a cow trevally! No wonder my head hurts so much! ”

If Mandy knew what an Antarctic Immortal was, he would definitely find that he was very similar to the Immortal at this time.

The trevally is not a rare fish, on the contrary, it is familiar to those who are familiar with diving and sea fishing.

Because it is so strong, powerful, and extremely ferocious, it often attacks the sea fish that are about to be caught.

Keko experienced it once, when a real sea bream was about to be caught, and he was about to reach out to catch it, but a huge cow harbour trevally suddenly rushed over and swallowed the real sea bream in one bite, startling him so much that he almost fell into the sea.

Even people dare to grab their prey, which shows how fierce the Niugang trevally is.

Because of its infinite strength, very flexible, and extremely fast swimming speed, and very strong combat effectiveness, the Niugang trevally is known as the bison in the water.

If you can catch a trevally, it will be a great honor and a sense of accomplishment.

So far, the cow harbor trevally has become famous in the sea fishing world, and has become the ultimate target fish of sea anglers, as a sea angler, a restless desire in the heart, wanting to conquer the huge, powerful monster.

It's just that there are not many people who succeed, and a lot of them are dragged into the water.

The same is true in the diving world, where many divers are sometimes more scared than sharks by sighting cow trevally.

Keko hurriedly asked, "And what about it now?" He's dead? Or what? By the way, what about your oxygen cylinder? ”

Bi Fang shook his head, just now under the water, on the one hand, he was carrying Mandy, who was unable to move, and secondly, no one could say for sure how long the grappling time was, in case the time was too long, Mandy was prone to burping.

At that time, the sound of the water was already more than 30 meters, and if you often dive, you will know that there is a critical point in the natural floating of diving, that is, between 30 and 40 meters underwater.

Under pressure, you no longer need to swim 30-40 meters underwater, and your body density will become very high, allowing your body to sink naturally and then enter the "free descent phase".

This is also the most wonderful stage of diving, where you don't have to do anything and you get pushed into the depths of the ocean.

But the situation was not rosy for Mandy, it was deadly.

Once Bi Fang lets go, this guy will naturally sink to the bottom of the water, and he is already in a state of drowning, and no one can guarantee what will happen, in case he fights with the Niugang trevally for too long, this guy may be gone.

Drowning and suffocation are completely different.

The relative time to death will be very fast, usually only about 2-3 minutes.

Large amounts of water enter the lungs and stomach in a short period of time.

Pulmonary edema, severe dilution of blood and tissue fluids, lack of oxygen exchange in the body, severe burden on the heart, and finally various symptoms are complicated, painful drowning.

This meant that there were less than two minutes left for Bi Fang at that time.

He was powerless to fight, and he couldn't fight.

So Bi Fang was in a hurry to use the method of striking the east and west, and it was impossible to throw things too far in the water, so he tied the flashlight with a breathing tube, and then opened the gas valve of the oxygen cylinder, and used the air pressure to drive the flashlight to form a swimming light column on the bottom of the sea.

It's not a one-size-fits-all trick, it depends on the fish.

Changing fish may not have such a good effect, or even be useless.

Mandy and Keko looked at each other, puzzled.

Bi Fang stood up and explained: "The Niugang trevally has a special preference for the plum snapper of the family Die snapper, as the next level of the food chain, the plum snapper fish have phototaxis and are very light-loving. ”

"The root cause of the trevally is that the creatures below the food chain they like light are fond of light, so they gather under the lamp to hunt."

"Maybe that's the reason why the Cow Harbor trevally attacked Mandy at the beginning, and when I saw a pillar of light, I mistakenly thought it was a plum bream, but I found out that it wasn't when I hit it."

Mandy was speechless when she listened, and she was unlucky when she co-authored?

The swimming flashlight sent a certain amount of misinformation to the trevally, mistakenly believing that there would be a more delicious plum snapper there.

With more delicious food, the Niugang trevally will naturally let go of attacking the two of them, which is thankless.

It's like Bi Fang hunting in the jungle, not eating for several days, and finally finding traces of animals, only to see that it was a wolf.

The wolf is the wolf, it's not that it can't be eaten, although the meat is firewood and fat, and it is still very dangerous, but it is not impossible.

But I wanted to fight the wolf, but a lame pheasant suddenly passed in front of you.

Even fools tend to be biologically instinctive to abandon wolf meat in favor of tastier and more accessible chicken.

Mandy and Keko suddenly realized, and looked at Bi Fang in astonishment.

From the time the incident happened to the landing, in less than two minutes, when normal people were scared and stupid, Bi Fang was able to find a way to break the situation from the attacker's diet.

What the fuck is this human doing?

Bi Fang took off the wetsuit on the upper half of his body, and found that the middle and upper part of his right arm were swollen a little, and the color was darker, obviously red and swollen from the impact.

Mandy and Keko were silent for a moment, although they were shocked and felt outrageous, but if they were placed on Bi Fang, it was normal.

The only problem is......

"And now? Now what? Will the trevally still be down there? ”

The two asked.

It's only eleven o'clock now, and most of the task is still unfinished, so what should I do next?

The meat of the cow harbor trevally is not delicious, the meat is rough, the fishy smell is very large, and it is generally used for animal feed.

The more this is the case, the more it proves the horror of the trevally.

"It's simple." Bi Fang put the wetsuit back on, "Just slaughter it." ”

"Zai...... Slaughtered? ”

The expressions of the two were wonderful.

Bi Fang picked up the spare oxygen cylinder on the side, ran to the woods on the side, and pulled out a wooden spear.

The whaling fork has been plated with an anti-corrosion metal layer and is not afraid of seawater, but Bailian Steel does not, so Bi Fang was initially reluctant to bring it into the water.

When fishing in the sea, the harpoon is the weapon.

Using the same manoeuvre, the whaling fork was attached to the wooden spear, and Bi Fang jumped into the sea again as Mandy and Keko watched, moving closer and closer to the depths.

"Wait, he didn't have a flashlight!" Keko exclaimed.

Mandy twitched the corners of her mouth and looked up at the moon in the sky.

"I don't think he needs that."

"What are you kidding?"

"yes, what a joke."
