At this time, if it rises too fast, it will cause the nitrogen dissolved in the blood and tissues to be unable to release and circulate normally, forming a large number of bubble blockages, which is also known as diver's decompression sickness, and even death in severe cases!

When Li Xiaofeng surfaced on the surface, he found that he had unknowingly left the fishing boat for a long distance just under the seabed.

At this time, he opened the thruster hanging on his body, swam quickly in the direction of the "Deep Blue" at full speed.

After a while, Li Xiaofeng was about to swim to a place not far from the fishing boat, when the sharp-eyed Li Xiaoliang suddenly saw him and waved to greet him: "Brother Feng, you're back!"

Li Xiaofeng also waved at him, and then continued to swim towards the fishing boat.

When he got to the side of the boat, Li Xiaofeng also shouted to him: "Xiaoliang, you go and get the rope to hang down, and then help me get a net again!"

"Okay, Brother Feng, then you can wait for me for a while!" After speaking, Li Xiaoliang trotted all the way and ran towards the cabin. Li Xiaofeng did not board the boat, so he continued to wait in the water.

It didn't take long for Li Xiaoliang to run back again, and then he took one end of the rope in his hand and threw the other end down.

Li Xiaofeng untied the net pocket on his body, put it on the rope hanging down, and then shouted to Li Xiaoliang: "Xiaoliang, after pulling the things up, help me put them in the water tank in the precious seafood storage area and raise them!"

"Okay, Brother Feng!" Li Xiaoliang replied with a smile, "I happened to see what valuable goods you have caught, Brother Feng."

When the net bag was pulled up to the deck and the contents of the net pocket were clearly seen, there was an exclamation from the deck!

Li Xiaoliang's voice was the loudest: "Oh my God, this bag is full of sea cucumbers, and an individual type is still like this, this is worth a lot of money!" Hey, why is there a white sea cucumber?"

Then he looked at Li Xiaofeng and asked, "Brother Feng, are there still white sea cucumbers?"

"Isn't that what you have in your hand?" Li Xiaofeng said with a smile, "Why don't you throw me another net bag quickly, and I'll tell you more carefully when I get back to the boat." Remember to put them in the tank and add the cleanest seawater!"

Sea cucumbers are amazing, you can say that they are tenacious or delicate.

It is said that its vitality is tenacious because when the sea cucumber encounters danger, it can directly spray out the internal organs through the contraction of its body to attract enemies, and then take the opportunity to escape by itself.

A sea cucumber that has lost its internal organs does not die, and after a few weeks of growth, new internal organs will grow back into its body.

There are also some sea cucumbers, which have been eaten half by some natural predators, and they can also regrow their bodies.

Even if a sea cucumber is cut into three pieces and thrown into the sea, each of them will grow into a whole sea cucumber.

If you say that it is fragile, sea cucumbers generally have to hibernate to avoid the heat in the summer when the temperature is relatively high, and this time can sometimes be as long as 100 days.

When the sea cucumber is hibernating, it looks like it is dead and has no reaction at all, and it is even as stiff as a stone.

If the temperature of the sea continues to rise at this time, after reaching a certain temperature, it will also trigger an autolytic enzyme in the sea cucumber. ….

Under the action of this autolytic enzyme, the sea cucumber will turn into a puddle of water and disappear without a trace in the water.

In addition to high temperatures, oil stains, the salinity of seawater, and even hair can pose a deadly threat to sea cucumbers, so sea cucumbers are sometimes really vulnerable.

Li Xiaoliang also grew up by the sea since he was a child, and he also knew a little bit about the characteristics of sea cucumbers, and when he heard Li Xiaofeng say this, he hurriedly agreed and said, "Brother Feng, don't worry, I will definitely take care of these sea cucumbers!"

Seeing that Li Xiaoliang understood what he meant, Li Xiaofeng nodded, and after taking the net bag thrown down by Li Xiaoliang, he dived to the bottom of the sea again.

After a while, Li Xiaofeng came to the bottom of the sea again and began to catch sea cucumbers everywhere in the coral.

I have to say that this sea area is really full of life

In the process of searching for sea cucumbers, Li Xiaofeng also found a lot of strange fish, various crabs and lobsters.

If this was a normal time, he would have done it to them, but this time he couldn't bear to do it because he needed to catch more valuable sea cucumbers.

It wasn't until he found a large blue grouper more than a meter long and weighing more than 30 pounds in a cluster of corals that his hands couldn't help but itch.

Li Xiaofeng hadn't seen such a big bluestone spot for a long time, and he hadn't touched the fishing gun for a while, so he hesitated, but couldn't help but pick up the fishing gun and aim at the big blue spot that was swimming.

Then taking advantage of the moment when the big grouper turned around, he decisively pulled the trigger of the fishing gun. Then the arrow attached to the fishing line flew out like a bolt of lightning, and instantly shot into the head of the big grouper, and pierced directly from the other side.

The large blue grouper that was shot dragged out with the fishing line, and then struggled in the water a few times before floating motionless in the water.

One shot kills!

Li Xiaofeng, who was overwhelmed, happily pulled the fishing line and pulled the big grouper back.

Then he looked at the map again and changed directions, and continued to search for the sea cucumber hiding at the bottom of the sea.

The water in this direction is still clear, beautiful corals are everywhere, and seaweed is flourishing.

In addition to these seaweeds, there are also strange "chrysanthemums" blooming in the corals.

Some of them are colorful and crystal clear, some are packed to be put away, and some are drooping gold threads, like a chrysanthemum exhibition, dressing the bottom of the sea into a colorful and flowery world.

These things, which look like colorful chrysanthemums, are not actually plants, but sea anemones, which belong to the coelenterates.

And don't look at their beauty, they look like colorful chrysanthemums, but in fact they are one of the most ruthless killers under the sea. Each of its tentacles that stretches out in the water has a lot of poisonous cells growing on it.

As soon as some fish swim close to them, they will mercilessly eject the stingers on their tentacles, causing the prey to be poisoned, anesthetized or killed, and become its food.

Even Li Xiaofeng, who was wearing a thick diving suit, had to carefully avoid these poisonous sea anemones and continued to search for sea cucumbers among the corals.

It didn't take long for the net pocket he carried with him to be filled with large and thick sea cucumbers, most of which were plum ginseng distributed more in the South China Sea, and a small amount of topaz ginseng and black cucumber.
