In the abyss of nearly a thousand meters, Su Mo looked at the pearl nautiluses not far away, and couldn't help but have a lot of thoughts in his heart.

I recall that the first pot of gold he earned was a snail, and now in search of the four sea snails, he unexpectedly discovered the pearl nautilus, one of the four sea snails.

Isn't this a kind of fate?

The pearl nautilus first appeared in ancient times 5 million years ago, but at that time, it was still an apex predator with a body length of more than 10 meters. After hundreds of millions of years of evolution, most of the creatures at the same time have become extinct, but the nautilus has thrived to this day with its unique body structure.

Speaking of its body structure, we have to mention an interesting thing, because the nautilus's shell has about 30 chambers separated by diaphragms, but its body is hidden in the deepest chamber. , the other chambers are filled with gas.

Nautilus can control its buoyancy with the help of the inflow and outflow of gas and seawater in these chambers, allowing it to move freely in the sea. Humanity also learned from the nautilus's principles of water drainage and water absorption, floating and sinking, to build the world's first submarine. In order to commemorate this magical ancient creature, the world's first nuclear submarine was named " Nautilus".

However, even though the evolution of the nautilus is legendary, because of its beautiful patterns and unique shape, it has inevitably become an "art piece" and is collected by dignitaries.

As the saying goes, when there is a transaction, there will be risks.

Due to intensive fishing, the nautilus that once existed in the world's seas has been almost extinct. Even Su Mo saw a living nautilus with his own eyes for the first time.

I counted casually and found that there were 6 nautiluses in the coral reef below, 4 of which were about 20 centimeters, and the remaining two were smaller, less than 10 centimeters. Although they looked small, Su Mo knew Nautilus grows extremely slowly, and it may take nearly 20 years to reach 20 centimeters.

Moreover, it is very rare that there are 6 such rare nautiluses here. They seem to be a small group, ranging from big to small. But thinking about it, they probably can only survive today by hiding in the inaccessible Mariana Trench.

After thinking about it for a long time, Su Mo finally decided not to take back these endangered nautiluses. First of all, nautiluses are now protected animals. Even if he had the means to sell them secretly, he could indeed make a lot of money. But now he is actually not very short of money, and there is no need to do this kind of risky and desperate business.

But Su Mo is a common man after all. Although his conscience is still there, he still can't do anything without taking the treasure when he encounters it.

Since we can’t take the alive ones back, what about the dead ones?

This is where their group gathers. Are there any dead nautilus shells?

Thinking of this, Su Mo immediately swam to the coral reef and started searching. But even though he had searched carefully enough, in the end he found that except for these nautiluses and the large leatherback turtle lying there motionless, there was nothing else of value.

"Forget it."

Su Mo smiled bitterly in his heart, no longer worrying about the baby, and prepared to leave here and continue looking for his white jade sea cucumber.

But just when he turned around, an idea suddenly came to his mind.

"I encountered that big sea turtle when I was searching just now, but it couldn't move. Although it is one of the largest sea turtles in the world, the leatherback sea turtle is also known as a 'swimming expert' because of its speed. If you are not slow, there is no way you will not react when you encounter outsiders."

Thinking of this, Su Mo immediately turned back and squatted in front of the leatherback sea turtle that was over two meters long.

Suddenly, one person and one turtle looked at each other, and Su Mo realized that this guy was a little abnormal. Not to mention that it was very weak now, and there was a small piece of transparent object twisted into a ball outside its mouth.

Su Mo stretched out his hand and pulled slightly, and the leatherback turtle shook its head feebly, as if in great pain.

"This......"

She already knew from the touch just now that it was a large ball of plastic film, which looked like it was used to cover supplies on freighters.

After a moment's thought, Su Mo guessed that the leatherback sea turtle must have eaten the plastic film as a jellyfish. The plastic film was so tough that the turtle's stomach couldn't digest it at all, so it was blocked. The intestines are occupied, lying here waiting for death.

"Brother Turtle, you are really lucky this time. If you hadn't met me, you would have been dead."

Su Mo immediately grasped the plastic film outside the corner of the leatherback sea turtle's mouth and pulled it hard. The plastic film was pulled out by more than ten centimeters.

In an instant, the leatherback sea turtle struggled in pain. After all, it was pulling something out of its intestines. This was the same as a human undergoing a gastroscopy. It felt really uncomfortable.

"do not move!"

Su Mo pressed hard with his left hand, immobilizing the turtle, which probably weighed several hundred kilograms, and then continued to pull on the plastic film.

It took him more than ten minutes to pull out a piece of plastic film that was nearly one meter long.

After a while, although the leatherback sea turtle was still very weak, the "illness" had been resolved and it was finally able to move.

But the first thing it did after recovering was to use its thick limbs to quickly pull the sand and gravel under it, until it made the surrounding sea water turbid, and even a few small stones hit Su Mo's body. .

"Damn it, you stupid turtle!"

Su Mo cursed in his heart and quickly retreated several meters away.

The leatherback turtle continued to pull for a while, until it was exhausted and then stopped, and then swam towards the sea above without looking back. The speed simply overturned Su Mo's understanding of turtles.

"Fuck, you said turtles are psychic. That's all a fucking lie. Look, this turtle is just repaying kindness with revenge!"

Su Mo was so angry that he wanted to catch up with the guy and beat him up. However, in the end, he was not as experienced as a turtle. After the turbid seawater around him settled, he was ready to continue diving to find sea cucumbers.

But at this moment, he suddenly discovered that a large pit had appeared where the leatherback turtle had been lying just now, and there were several strange-shaped stones in the pit, some resembling pagodas, some resembling bamboo shoots, and another The big thing that looks like a millstone is covered with beautiful patterns like nautilus!

Su Mo rubbed his eyes, opened his mouth in disbelief, and almost drank the seawater into his stomach.

"Let me go, are those Chinese Cathay Corner Stones?"

"Nima, is this big guy an ammonite?"

"Fuck, Brother Turtle, I admit that I was too loud just now. I apologize for my behavior just now. You are really psychic!"
