At this time, Li Xiaofeng's eyes lit up, and he saw the guy hiding under the coral reef, comparable to the thickness of an adult's calf, with a dark brown body, and slowly squirming.

"Sea cucumber!" Li Xiaofeng happily stretched out a hand and grabbed it out from under the coral reef.

Speaking of which, this guy moves slowly, has a soft body, and has no lethal weapons on his body, so I really don't know how they survive in the fierce competition at the bottom of the sea.

Li Xiaofeng put the sea cucumber in his hand and played with it for a while, and then put it in the net pocket he was carrying.

This is not an ordinary wild sea cucumber, but a plum cucumber, one of the largest sea cucumbers among them! The average sea cucumber is not that big.

Speaking of sea cucumbers, they have not been one of the most valuable supplements in our country since ancient times, along with ginseng, bird's nest and shark fin!

In addition to this, sea cucumber is also considered one of the most valuable medicinal materials.

It is recorded in the "Compendium of Materia Medica": sea cucumber, sweet and salty, tonifying the kidney, benefiting the essence, taking urine, aphrodisiac and curing aphrodisiacs, its sexual temperature supplement, enough enemy ginseng, hence the name sea cucumber.

Modern medical research has also proved that sea cucumber has a variety of effects such as improving memory, delaying gonadal aging, preventing arteriosclerosis and anti-tumor.

There are more than 900 kinds of sea cucumbers in the world, and there are about 140 kinds in China, but only 20 kinds can reach the edible level, which is one of the reasons why the price of sea cucumbers has been very high.

Among the world's seas, the Indian Ocean and the western Pacific Ocean are the regions with the largest variety and the largest resources of sea cucumber in the world.

In China, sea cucumbers are mainly distributed in temperate and tropical regions, and the temperate zone is mainly in the Bohai Sea, especially in the coastal areas of Liaoning and Shandong, which are also one of the most concentrated areas of sea cucumber breeding in China.

The tropical region is mainly concentrated in Fujian, Liangguang and Hainan coasts, and its Dongsha Islands, Xisha Islands, Nansha Islands and Hainan Island are the main producing areas of plum ginseng, the main economic variety of tropical sea cucumber in China.

The tropical areas of the captive-cultured sea cucumber area are mainly concentrated in the coastal areas of Fujian and Guangdong.

Sea cucumber is not only one of the "Eight Treasures of the Sea", but also known as the "First of the Eight Treasures".

Wild sea cucumbers are expensive, but due to overfishing, such as some relatively large wild sea cucumbers, except for some remote sea areas, it is difficult to find them in China.

However, even if it is farmed sea cucumber, the price is not cheap.

The price of a pound of dried sea cucumbers that meet the standard can also reach thousands or even tens of thousands, and it is said that the sea cucumbers eaten by the national football team are as high as 120,000 catties, and I heard that a person has to eat several a day!

I don't know if it's because the sea cucumbers have eaten too much, and they can't do it too much, causing them to have soft feet.

There is also a saying in the industry that you can't buy any good sea cucumbers for less than 3,000 yuan.

Generally, the market price of sea cucumbers that reach the third level of the national standard can reach 3,000-4,000 yuan; If it can reach the national standard level, the market price will be as high as 6,000-8,000 yuan; If it can reach the national standard special grade, the market price has reached 15,000-20,000 per catty.

That's why sea cucumbers are also known as "diamonds on the table"!

Of course, some people will say that the price of the sea cucumber I buy is very cheap, you must know that the water is really deep in the sea cucumber industry.

These cheap sea cucumbers, maybe you eat them, will be more troublesome than not eating them.

It is precisely because the price of sea cucumbers is so high that Li Xiaofeng will specially arrange for Meng Guangming to drive the boat back.

This seabed, covered with reefs and corals, has not been disturbed by humans for I don't know how many years.

In other words, it seems that only Li Xiaofeng can see this calm seabed from the map, and there are so many sea cucumbers scattered all over the place.

Although there are a lot of these sea cucumbers, most of them are distributed in some hidden corners, and it is not easy for ordinary people to find them.

Then Li Xiaofeng took the net pocket and began to get busy under the seabed.

He is the only one here, and he can choose these sea cucumbers to his heart's content at the bottom of the sea.

Don't be too small, don't be incomplete, don't have too few spines......

Even so, the net pocket he carried with him would soon be filled with these thick sea cucumbers.

At this time, Li Xiaofeng found a sea cucumber on the map. Following the map's instructions, he came to a dense coral grove, leaned down, carefully avoided the sharp corals, and put a hand inside.

It didn't take long for his hand to reach for something soft and carefully take it out.

The moment he saw it, Li Xiaofeng's heart couldn't help but bloom, because in his hand it turned out to be a white sea cucumber.

There is a saying among the folk that "a thousand years are black, ten thousand years are white", which also shows the rarity of white sea cucumbers. In the past, some people even called white sea cucumbers "Samshen"!

In fact, this white sea cucumber, also known as white jade cucumber, is the product of genetic mutation of sea cucumber, which is extremely rare in nature, with an average of only one in 200,000 sea cucumbers.

In addition, white ginseng also has extremely strict requirements for the water quality of seawater, and they cannot survive if they are slightly polluted, so it can be said to be very precious!

At an international sea cucumber cultural festival in Jinan, China, there was a white jade sea cucumber, which was finally auctioned at a price of 330,000 yuan per kilogram, which was also a new record of "the most expensive sea cucumber in history" at that time.

That's why Li Xiaofeng was so ecstatic when he saw this white jade ginseng that was not quite large. You must know that the sea cucumber in his hand weighs at least five or six catties, where is this sea cucumber, this is clearly a piece of gold!

He was relieved when this precious white jade ginseng was carefully received by him in his net pocket.

In fact, in addition to the selenium content in the body is a little higher than that of ordinary sea cucumbers, the other nutrients of white jade cucumber are no different from ordinary sea cucumbers.

Of course, people are willing to spend such a large price to buy it, probably because of the rarity of white jade sea cucumbers.

After collecting the white jade ginseng, Li Xiaofeng continued to follow the map and fished the sea cucumbers everywhere.

I have to say that sea cucumbers, which can only crawl by muscle stretching and contracting, and move at a speed of up to 4 meters per hour, are really easy to catch. Coupled with the map detector that Li Xiaofeng also has, this is simply his home field!

In less than half an hour, the large net pocket he was carrying was already stuffed with sea cucumbers as small as an adult's arm.

Seeing that the sea cucumbers in the net pocket were really no longer stuffed, he looked at the map again, and found no danger, so Li Xiaofeng floated up with a large bag of sea cucumbers.

However, this time he ascended much slower than when he dived before, mainly because he was diving very deep this time.

In this deep dive of more than 80 meters, the ascent is a transition from a high-pressure environment to a low-pressure environment.
