Evolution from the crocodile

Lu Chen fully understood that he had not bumped into a sunken ship on the bottom of the sea, but happened to stumble upon a large-scale counterfeiting site of salvaged porcelain? !

This kind of fraud had been exposed in previous lives, so Lu Chen naturally knew about it.

Hailo porcelain has been lying dormant on the seabed for hundreds or even thousands of years. The glaze of the artifacts is severely corroded by sea water, and a layer of calcium carbonate minerals will form to adhere to the precipitate.

In addition, many porcelains also have impurities such as shells and corals stuck to them.

Humans on fishing boats make fake products based on these characteristics: they soak the fake products in sea water and regularly sprinkle bait to attract fish, shrimps and shellfish to attach to and excrete on the vessels.

It is estimated that in a few months, these so-called porcelain from the sea will be available.

You can even take the buyer directly to this sea area and let the buyer witness the sea salvaged porcelain being salvaged from the water on the spot.

But knowing all this was of no use to Lu Chen now, and he didn't have much time to worry about.

He just noted down the specific location and quietly surfaced from a distance.

It's been a long time since I went to sea, and it's almost time to go back...

The sea water is vast and there are no obvious reference objects around.

With the help of the magnetic field induction and discrimination ability in the brain of the crocodile, he still easily determined the location of the nest.

Quack...quack...

Chirp chirp...

Just after swimming for more than ten miles, there was a sudden sound from the sea water.

The sound is very unique, deep and high-pitched, a bit like the squeaking sound made by children playing with deflated balloons in the past, and also like the croaking of frogs...

This is obviously an abnormal fluctuation caused by fish schools, and there must be big goods ahead!

I didn't expect that I would be able to have another hearty meal before returning to the shore.

GO, GO, GO!!

Lu Chen became excited and hurriedly waved his limbs, looking for the sound and rushing over.

After swimming hundreds of meters, the sound became clearer and clearer, with very strong penetrating power.

The hearing of the crocodile is very developed, with a frequency range of 20-6000Hz, which is much lower than that of humans. So you can easily hear the subtle and low sounds in the sea water.

But at this moment, Lu Chen felt extremely noisy, even flustered and irritable.

It was as if someone was making a sound with an electric drill nearby, making him subconsciously want to stay away.

What the hell? Lu Chen hurriedly raised his head high above the water. The noise finally weakened a lot and was barely bearable.

After swimming forward for several dozen meters, seven or eight rocks of different sizes appeared on the sea surface ahead.

A dazzling golden light suddenly appeared outside the reef area!

School of fish, such a big group of sea fish!

Big yellow croaker!

After seeing the appearance of these sea fish clearly, Lu Chen immediately became excited.

The large yellow croaker is a type of kingfish and is also called cucumber fish, sweet-scented osmanthus yellow croaker, and red melon fish.

In the eyes of many rich people, its status is equivalent to that of abalone and lobster.

Even people who don’t know much about seafood have probably heard the name of this fish.

Due to long-term fishing in previous lives, wild large yellow croaker has become very rare. The price has been rising all the way, and there is even a saying that yellow croaker is as expensive as gold.

Lu Chen once read a piece of news: A fisherman went out to sea to catch 60,000 kilograms of yellow croaker, and finally sold it for a high price of millions.

It's a pity that as a crocodile now, he can only watch his wealth slip away.

However, it is still possible to catch a few and try them out.

Lu Chen swam closer and discovered something unusual again.

This group of large yellow croakers kept running forward, as if something was chasing them.

Just as he was guessing, three gray-black figures suddenly appeared.

Dolphins, dolphins are hunting.

Their bodies are spindle-shaped, gray-black, smooth and smooth, with curved hook-like fins on their backs.

The largest one was more than three meters long. To Lu Chen, it was definitely a giant.

He completely understood the whole story. No wonder these big yellow croakers made such high-pitched calls to avoid being hunted by dolphins.

In addition to its relatively yellow color, the large yellow croaker is most famous for its cry.

Totoabas are the rare fish in the ocean that like to make sounds during mating and spawning, and the giant yellow croaker has this skill to its fullest. When the male fish is in love, he cries quack, which is extremely high-pitched and loud. The female fish calls out Gawu... Gawu..., which is low and tactful.

Male and female Pisces are like butt joint signals. If you find the right frequency, you can clap and play happily with each other.

Of course, their calls are not only used to court mates, but also serve to scare away powerful enemies.

Because a single large croaker can emit a sound of up to 177 decibels. In previous lives, it was determined that the maximum noise that humans can tolerate (without causing hearing loss, sleep disorders, anxiety, learning disabilities, etc.) is 70 decibels.

From this we can see how terrifying it is for countless large yellow croakers to make sounds at the same time, which is enough to disrupt the auditory system of natural enemies.

It can cause temporary deafness in mild cases, or permanent deafness in severe cases.

It's just that the group of dolphins in front of us are obviously smarter. They don't always come close to hunt the big yellow croaker.

Instead, it jumped out of the water intermittently and far away, as if flying a kite.

No wonder the Internet says that the IQ of dolphins is equivalent to that of a 4-6 year old human child. These guys are so smart and understand the essence of guerrilla warfare.

In a different environment, Lu Chen would definitely watch the dolphin show quietly.

Now, it's still important to grab food.

If you let these guys catch them, you probably won't get much benefit.

As for hunting dolphins, Lu Chen had no such extravagant hopes.

This guy is a proper sea swimmer. Under normal circumstances, they can swim 50 kilometers per hour, almost as fast as a bus.

If you run away from danger, your instantaneous speed can reach 15 meters per second.

Unless you choose to hide and ambush in a specific location, there is no possibility of hunting.

It's better to eat two more large yellow croakers to fill your stomach and save money.

After making up his mind, Lu Chen quickly swam to the school of fish and opened his mouth wide.

Schools of large yellow croakers gather together, and the density is too great.

Click!

Without much effort, a croaker was caught in the mouth and swallowed immediately.

However, the screams of the large yellow croakers were too noisy, and Lu Chen was also harassed while hunting. At this moment, my mind was getting more and more agitated, and I naturally ignored my surroundings.

Just as he was preparing to hunt again, an indescribable sense of crisis suddenly came into his consciousness.

Just like...that time I got diving sickness.

dangerous! ?

Lu Chen didn't care about intercepting the big yellow croaker anymore, and hurriedly opened his eyes and looked into the surrounding sea water. At the same time, the limbs paddle rapidly and rush towards the water surface.

A few seconds later, a terrifying figure appeared from the sea.

The back of the body is dark gray, with 2 dorsal fins, no ridge, and the ventral side is gray. The wide mouth opened slightly, revealing rows of sharp, fine serrations.

A pair of slightly protruding round eyes revealed a ferocious aura.

This is a shark!

Damn it, bull shark!

As a fan of Animal World in his previous life, Lu Chen quickly recognized the other party's real name - Bull Shark.

This is a large shark that lives in bays, estuaries, rivers or lakes. It is also the only shark that can penetrate deep into freshwater rivers and even live in lakes.

At the same time, it is also one of the three most dangerous shark species to humans (the other two are tiger shark and man-eating shark). It mainly feeds on bony fish, but also preys on other sharks, crustaceans, cephalopods, Sea urchins, sea snakes, turtles and more.
