Those years of engaging with the system for animal insurance

This fishing boat is not big, only seven people, the captain couple and five crew members.

These seven people are typical fishermen from the Thousand Islands, with darker skin tones.Just salvaged a net of fish, sorting under the sun.

Among them, the captain looked at several shark fins in his hand.

It is just cut from that shark, and it is the main raw material of shark fin.

"Boss, this time is considered a windfall. I hope there will be more." One of the crew members said to the captain.

The captain smiled and said: "You boy, what are you thinking? If you are caught, you will be fined. Besides, how can you have such good luck to let you catch sharks with a net. We can't sell high prices for our first-hand sources. "

Li Cixin marched against the bottom of the boat, so he could better hear the conversation.

Shark's fin, one of the Eight Treasures, occupies a place of high-end ingredients no matter how other food lists change.It can be seen that its status in people's minds.

I don't know when people discovered the food of shark's fin.In Huaxia Kingdom, shark fin has been widely eaten in the mid-Ming Dynasty.

Because of the coastal waters of China, there are few shark resources.Therefore, whether it is ancient times or modern times, most shark fins in China are imported.

Although Huaxia ranks lower in the world in terms of shark hunting, it is a big consumer of shark fins.

Therefore, many foreign media often grab people's attention by saying that China has caused sharks to become endangered.

But in fact, this is a kind of racial prejudice.

With the advent of the new era, various non-profit organizations are carrying out publicity in China, and the slogan "No sales, no killing" is also posted all over the streets and alleys.

Coupled with strict government control.

Huaxia's ivory, rhino horn, crane crest red, shark's fin...the trading volumes all fell precipitously.

Among them, the consumption of shark fin dropped by [-]% directly, and the total number of customers decreased by [-]%.

But even so, it still hasn't changed the total number of sharks caught in the world.

In the market where the shark fin trade is declining, relevant statistics show that shark meat is the main one, accounting for more than half of shark products.

In fact, because sharks survive in sea water, they adapt to salt water and maintain their lives.They accumulate urea under the skin to balance the osmotic pressure between the body and seawater.

Urea is one of the main components of urine, so there is a widely circulated saying that shark meat has a urine smell.

But even so, shark meat still accounts for the majority of shark products.

Because the saying that shark meat has a peculiar smell has convinced many people, but will human beings give up eating a piece of meat because it has a peculiar smell?

Like sharks, rays, manta rays and other fish also have a peculiar smell, but they are still served on the table.

Facts have proved that even if sharks have evolved their meat to smell like urine, they still can't hide from human mouths.

When the shark fin trade was very prosperous, fishing boats going out to sea would cut off the shark's fins and throw the sharks into the sea to reduce the load.

As for the family-run fishing boats encountered today, they are incapable of killing sharks in large numbers.Generally, it is a matter of fate, which is the so-called "by-catch".

Some videos are often circulated on the Internet, such as fishing boats netting sea lions and sharks, and finally released them.With the sharp shrinkage of the shark fin market, and the improvement of the government's animal protection laws.

Normally, fishermen release the sharks they catch.

Of course, where there is profit, there is slaughter.This fishing boat was not very big, and it was easy for Li Cixin to overturn it.

However, he did not lift the boat. After all, bycatch is a low-probability event, but the other party still did not let the shark go, and he still had to teach him a lesson.

The heavy tentacles emerged from the water, boarded the fishing boat, and forced it down by more than one meter.

The captain and the crew were shocked. They all knew octopus claws, but this was the first time they had seen such thick and sturdy ones.

Like two giant pythons clinging to the boat, forcing the boat to stop.

The captain's wife, who was preparing lunch in the cabin, even forgot to turn off the fire and came out with a spoon.

"My God, what is this thing?"

"Octopus! Big octopus!" The captain's voice trembled a little. Although it was the sun at noon, the seven people on board felt their hairs stand on end.

A few seconds later, Li Cixin's huge head appeared in front of them.

The captain's wife screamed in horror, and the husband on the side quickly covered her mouth!Afraid to provoke the monster in front of him.

For more than ten years, they have been fishing for more than ten years, and this is the first time they have encountered something more terrifying than a storm.

"I... thought my grandmother... told a false story..." One of the crew members said this with a trembling voice.

Li Cixin looked at him, this action completely frightened these people to open their mouths.

They realized that the monster seemed to understand what they were saying!

Seeing that several people were petrified, Li Cixin raised a tentacle and stretched it towards the captain.The captain hugged his screaming wife tightly, not knowing what the big octopus was going to do.

Seeing that the other party hadn't moved for a long time, Li Cixin pointed to the shark's fin on the board, and the captain quickly squatted down, holding the shark's fin in his palm.

The huge tentacle rolled the shark's fin, and the other tentacle pointed at the shark's fin in front of the seven people, shaking it to signal them:

'If you catch sharks again, I'll...'

Then the tentacles curled up into a fist shape.Although the threat was unexpected, Li Cixin was still not sure if the other party understood what he meant.

Obviously, they understood, and several of them nodded.said:

"Octopus... Oh no, Lord Seagod, we won't catch sharks anymore, and we don't want to hunt shark fins anymore. I beg you to be merciful and let us go."

The captain led the people to kneel on the boat, and bowed to Li Cixin on board.

Seeing this and getting the promise he wanted, Li Cixin released the restraint on the fishing boat and slipped into the ocean.Just when the people on board thought the danger had passed.

A tentacle quickly jumped out of the water, sweeping away all the fish that everyone had worked so hard to catch.This trip to sea was a waste of time.

"Almost forgot to teach you a lesson."

Li Cixin threw the fin at the place where the shark's body fell, and continued to swim away.Along the way, Li Cixin opened up his "kind and friendly" "communication" and "commitment" to the fishermen.

A week later, Li Cixin, who was wandering around, finally saw a professional shark hunting team.This boat not only catches sharks but also catches whales. Its equipment is even better than the previous family fishing boat by Everest.

On this boat, many sharks have been caught.Different from those ordinary fishermen who were for shark fins before, their techniques and steps are quite sophisticated.

They first poured blood mixed with fish meat into the sea to attract sharks.Sharks are known to be extremely sensitive to the smell of blood, and it didn't take long for many sharks to be attracted to the bait.At this time, the crew started fishing.

Sharks that are caught on board are quickly slaughtered and the crew will cut off their fins and put them together, although their main purpose is not shark fins.

The treasures of sharks are not only shark fins and meat, but also some places that many people have never known.

Among them, the huge liver on the shark is the biggest golden lump.

The liver owned by deep-sea sharks has another "wealth secret". A substance called squalene can be extracted from shark liver.

This squalene is a polyunsaturated hydrocarbon with a wide range of uses and has high moisturizing properties, so it is often used in daily chemical products.

Plants and humans also have squalene, but it is too difficult to extract, the cost is too high, and it is difficult to quantify it.

Shark liver is a perfect fit for this.

Not only that, the fish oil extracted from shark liver and the chondroitin in shark cartilage can be used in medicine or health care products.

While environmental organizers are decrying shark fin consumption, the real need is being ignored.

This multifaceted process continues to eat away at shark populations where people aren't looking.

The crew threw the sharks on the deck, then cut open their stomachs and took out the useful internal organs separately, leaving the useless ones thrown into the sea.The shark meat was quickly transported to the freezer in the cabin.

This is the difference between small fishing boats and big fishing boats. Shark meat is extremely perishable. Under normal circumstances, ordinary fishermen will not take them back, but such big fishing boats will make the best use of them.

Li Cixin rushed forward without any concealment.

Ten minutes later, watching the people struggling on the sea, Li Cixin, the instigator, drifted away.

As for whether the sharks attracted by humans with bait will attack them, let God think about it.

For the next few years he traveled to the Atlantic, to places like Fairyland and Forestland, which also had whaling traditions.

For this reason, he also left many terrifying legends. Some people say that he is the god of the sea, while others say that he is Satan.

However, the appearance of this elusive giant octopus has completely subverted people's perception of marine life.Too huge, never seen such a huge octopus.

Some countries even sent people to capture Li Cixin for research, but even nuclear submarines are not good for Li Cixin in the sea.

The ocean is wide and deep, as long as Li Ci plunges into it, there will be no trace.

For a while, in order to avoid being hunted by humans, Li Cixin dived into the deep sea. With the help of the system, he explored many world-famous trenches.

He was surprised to find that the life here can exist without sunlight, even in some places thousands of meters deep.

The seabed here is full of craters, and the temperature is extremely high. Under the huge pressure of deep water, it can even reach more than 300 degrees, but the life here can still survive.

All kinds of strange-looking arthropods, such as shrimps, crabs, crustacean clams, and big worms, as well as Li Cixin's current family, the octopus.

There is no light here, high temperature and high pressure, and there is actually a complete ecological chain.

After systematic popularization of science, Li Cixin finally knew that the reason why the organisms here can live without producers is because there is a kind of thiooxidans living near the submarine volcano.

The hydrogen sulfide continuously produced by the crater is their nourishment.The plankton feed on them, and the more advanced organisms feed on the plankton. In this way, a link is formed to form a living dark world.

Li Cixin also encountered a shark in some extreme depths, it was a sleeping shark.They have a Greenland sleeper shark, which is the longest-lived vertebrate found so far. It grows one centimeter a year, takes about 150 years to become photosexually mature, and can live up to 500 years.

Not only are there sharks in the cold, dark waters, but they are also found near undersea volcanoes.It is indeed a ruthless character who has existed on the earth for [-] million years and lived at the same time as the dinosaurs.

Dinosaurs have changed tack, evolved feathers and taken to the skies, while sharks remain among the ocean's top predators.

Of course, the system didn't help him to travel under the pressure of sea water for no reason.

It also came with the purpose of collecting genes. After all, the special genes of the creatures here are really of extremely high value.

Therefore, Li Cixin listened to the sound of the system beeping the whole time.

After avoiding the limelight for a while, Li Cixin acted more restrained.After wandering the ocean for several years, the mission was finally completed.

"Drip! The A-level task is completed, and the completion degree is C-level."

It's actually only a C-level completion degree, but thinking about it, the ocean is so huge, I have no skills to do it, and I have been hiding for a while, but the status quo has not changed much.

"Gene rewards are being sent now. Do you accept the transformation?"

Li Cixin learned about his genes this time, got out of bed, put on his clothes and walked out of the dormitory.

This time, I can't invite others.
