The sea is becoming more and more unfriendly to humans, and fish stocks in the sea have been declining since the 19th century – a trend that has been difficult to reverse since the development of industrial fishing. The East China Sea, which was once considered a fertile sea and one of the largest fish farms, is now almost empty of fish, and the pollution that has been washed into the sea has increased due to industrialization, which has led to a further deterioration of fishery resources. Overfishing and pollution have left the entire river and the East China Sea almost depleted of fish.

That was years ago, though. Since the appearance of the sea dragon in the sea, strange heavy metal bacteria and other bacteria have appeared in the world, these strange bacteria can decompose most of the organic and inorganic pollution, decompose these pollutants and enrich them, and then aggregate into a mud ball to sink to the bottom of the water, the efficiency of these bacteria makes them the best cleaners, can quite eliminate the pollution of the water body, reverse the eutrophication situation. Moreover, fish also began to breed after the appearance of sea dragons, and the success rate of reproduction increased several times. Within a few years, after the oceans were much cleaner, fish also multiplied.

But even fewer fishermen are available......

The huge brachiopods and crabs with carapaces of more than one meter in diameter, as well as the large sharks and large carnivorous fish that came out of nowhere, have appeared, making fishing more dangerous than ever. In particular, the Sea Dragon, the Sea Demon Medal, and especially the Sea Demon Chapter, which feeds on humans, these notorious sea monsters have sunk many fishing boats, making going to sea an unprofitable and risky business.

Biologists, especially paleontologists, are the happiest people. Because there is no doubt that the megalodon has been spotted, and sightings have been recorded in almost every part of the ocean, from the Mediterranean to the Pacific Ocean, the king of this huge shark - the number of whales has increased several times over the years, and it is really unknown how these animals were born. Not only that, but off the coast of Africa, huge schools of tiger fish have also been found, swimming in deep waters at least no smaller than adult great white sharks, attacking any prey that can be caught on any occasion.

And in the Atlantic, schools of strange fish have been reported, these four or five meters long strange fish have a hideous and terrifying appearance, and of course paleontologists recognize them - they are schools of swordfish...... The most feared school of carnivorous fish in the ocean. Coupled with the Melville whale and the giant turtle in the Caribbean, this is the age of sea monsters, and it is also the era of "keeping humans away from the sea".

The offshore aquaculture industry is partially finished under the interference of those big crabs and nearly ten meters long Pacific octopus and big squid, but fortunately, the taste of the big crab is good, although its crab roe is obviously bitter and not delicious, but the crab meat and crab paste are more and fat, the only regret is that these crabs are not easy to mess with, the male crab back carapace is nearly two meters wide, not at all spider crab or king crab kind of long-legged goods, that pair of crab claws are thick enough to clip human arms, and even male crabs seem to be able to clip off individuals is no problem...... These crabs are still in groups, and they are not to be messed with at all - because they eat people too.

The sea dragon is still basking in the sun on the beach, and the time this guy uses to hunt has decreased a lot recently, and he doesn't know why he has a bad appetite for flesh and blood now. But the monster didn't feel much hungry, and its physical movement didn't seem to be restricted, but lately it had become more and more lazy and didn't want to move, and just wanted to lie on the beach and bask in the sun. Hong Long's forty-meter-long body was lying across the beach, and his five-meter-long head was looking at the sea.

A huge fish leapt up from under the water, exposing its pale golden body with green tiger stripes to the sunlight, and then smashed into the sea. "Oh, isn't this the little brother? found me again?" Hong Long saw a familiar figure, it was the little brother of the tiger fish who swam with him across the Pacific Ocean, this guy's size seems to be at the end, and the body length of about twelve meters and thirteen meters is estimated to be the limit of this mutated giant tiger fish. When the tiger fish jumped out of the water again, it was biting a large octopus in its mouth, which was at least seven meters long and had most of its head bitten off very easily, but the tentacles were still wrapped around the tigerfish's body.

The tiger fish swam around the uninhabited island where Hong Long was located, and this time it seemed that after finding the sea dragon, the little brother of the tiger fish would not leave again.

The search for the sea dragon finally dropped a lot. The pharmaceutical company has finally reached a breakthrough in the analysis and synthesis of the active ingredients on the body of the sea dragon, and a certain organic compound has been synthesized in the laboratory, and after experiments on rats, it has been found that this is very close to the effect of the extract from the sea dragon - after all, the chemical composition is the same. It has a good effect on most cancers, especially for some malignant cancer cells, but it is a little different from the active ingredients on the sea dragon, this compound is a little more harmful to normal cells, and it is not as harmless as the ingredients on the sea dragon.

Compounds that kill cancer cells are not uncommon, but there are not many that can kill cancer cells in a broad spectrum, and even if the side effects are a little bigger, I am afraid that it is a large market in the billions of dollars. But it's clear that this is not the only ingredient that can effectively kill cancer cells and repair organ damage in the sea dragon. In the current situation of this dangerous sea, these benefits are enough to make the company no longer rush to send search ships to find the sea dragon when the situation of the sea dragon is uncertain.

The South China Sea was supposed to have become a safe sea area, after the Sea Demon Chapter and the Sea Dragon "died together". But it didn't—after the Sea Demon Seal disappeared, many large predators chased the fish into the area. Ordinary fishermen still don't have the ability or courage to go out to sea to fish, but when the large industrial fishing boats come to fish after a few months of closure, they judge that the place is safe and come to fish......

This terrible monster looks more powerful than it used to be, and although it hasn't grown in size, its tentacles seem to have become more powerful - which is also normal, originally it had twelve tentacles, but after the battle with the sea dragon, this monster only had seven tentacles left, and the rest of the tentacles did not regenerate. These seven tentacles occupy the territory of the previous twelve tentacles, so they are thicker and more powerful than the original tentacles.
