The water column that reached a height of ten meters slowly disappeared, and then continued to absorb air in summer and autumn, storing it in the lungs.

This black shadow that shoots out a column of water is Xia Qiu.

Strictly speaking, he does not spray a column of water, but the exhaust gas after breathing, and this air jet from the nostrils above his head carries the surrounding seawater with him, forming a column of water.

And the reason why I can breathe is because Xia Qiu's body structure changes again.

He had lungs, and two nostrils on the top of his head.

Growing your lungs on your own doesn't happen overnight.

Evolution can be extrapolated to about four years ago, when he hunted dolphins, and then hunted dolphins many times, and also hunted his own blue whales, and then hunted fish people.

Ordinary fishmen have more enhancement energy and less evolution energy, but they will not be absent, especially strong people like Aaron, Kroobi, and Jiu, not to mention that they have also eaten a lot of fishmen.

And the evolutionary energy is more than the evolutionary information of the lungs.

Coupled with the fact that he had previously hunted marine mammals, he grew lungs.

In summer and autumn, they can breathe on the surface, absorb oxygen, store it in their lungs, and then dive to the bottom of the sea.

A dive can take up to 20 minutes.

Being able to breathe with the lungs means that summer and autumn are on the way to the marine mammals.

Viviparous lactation, lung breathing, constant body temperature.

There is no way to determine this point of viviparity in summer and autumn, because the difference between viviparity and oviparity is that the former is a fertilized egg that develops and grows in a certain uterus, while the latter is a fertilized egg that develops independently outside the mother's body.

Xia Qiu can feel that he has Dingding, but there is no way to determine the breeding method.

But lung respiration and constant body temperature can be done in summer and autumn.

But Xia Qiu can't be counted as a mammal, because he hasn't lost his gills.

Not only can he breathe through his nostrils, but he can also suck water through his mouth, which he then filters with his gills to absorb dissolved oxygen from the water.

This allows Xia and Autumn to have two ways of breathing.

But unlike traditional amphibians, most amphibians use gills in the water when they are young, and when they grow up, they breathe with their lungs and skin.

In summer and autumn, it breathes with both gills and lungs.

Xia Qiu guessed that the reason why he was like this was related to the fish-man, who had both gills and lungs, and could switch freely between water and underwater.

This means that you can get out of the water.

If you only have gills, you can't be exposed to the air for a long time, because the structure of the gills causes the gill filaments and gills to stick together after leaving the water, and the breathing area is greatly reduced, so you can't replenish enough oxygen.

But the gills can breathe in the air, but there is too little oxygen, and over time, after exposure to the air, the gill filaments dry and the water vapor evaporates, resulting in the destruction of the gill structure, and then it will completely lose the ability to breathe, and then die.

But unlike yourself, you can switch your breathing mode when you are exposed to water, and you don't need to open your gill cover and expose it to the air, which causes your gills to be destroyed and you can't use it in water.

Just like the Fish-Man, you can switch it yourself.

So if you grow limbs on your own, maybe you can go ashore.

Maybe give it a try.

Xia Qiu thought, slowly dived into the water, identified the direction, and swam into the distance, Moo followed closely.

In the past three months, Moo has become Xia Qiu's follower.

As long as you follow Xia Qiu, you don't have to worry about stronger sea fish appearing, and there is meat to eat, so why not.

On the contrary, as long as you flee, you will be beaten by it.

So Moo accepted this reality, recognized Xia Qiu as the boss, and followed him to sail in this sea area.

Xia Qiu took him to swim into the distance, constantly looking for something.

After swimming for a while, Xia Qiu's sound waves captured the appearance of a behemoth on the water.

It's the ship.

It is located in the northwest direction, 3 kilometers away.

I hope it's a pirate ship.

Xia Qiu rushed towards the target, and Moo Moo followed.

Xia Qiu approached the sea ship a hundred meters away, slowly floated, and looked at the sea ship.

What appeared in front of me was a ship about forty meters long, and on board, there was a pirate flag with fangs.

Is it a pirate ship?

Xia Qiu's eyes lit up and rushed to the warship.

The huge body, carrying great power, directly crashed into the pirate ship.

Click.

The keel of the ship broke, and a crack appeared in the hull, slowly sinking downward.

Plop, plop.

One pirate after another jumped into the sea.

Xia Qiu did not attack, but waited quietly.

When the pirates in the ship began to swim and converge, Xia Qiu made sure that there were no pirates on the ship.

So Xia Qiu began to attack.

"Don't, don't."

A pirate looked at Xia Qiu's huge mouth, his face was full of panic, and he shouted for help, but to no avail.

Click.

Xia Qiu bit it up and swallowed it in his stomach.

Then he pursued and killed and ate a famous pirate.

Moo was waiting, knowing that the boss would not let him eat people, and he could only be beaten in the past.

After a while, the twelve pirates were all turned into Xia Qiu's belly meal.

But Xia Qiu's eyes were full of disappointment.

Too little, too little of the enhanced energy provided by these pirates.

All the pirates combined, there is only one enhanced energy provided by Colonel Lido.

Compared with the huge body size and physical strength of Xia and Autumn now, such heat flow is so rare that it is impossible to feel the qualitative change.

And it was too troublesome, and he attacked four pirate ships this month and ate four boats of people.

But this is what I picked out of hundreds of boats, and I floated up again and again, and I was disappointed again and again.

The physical strength wasted is more than the pirates who eat.

The East China Sea is not without powerful pirates, the Black Cat Pirates, the Kree Pirates, although not as good as the Evil Dragon Pirates, but they can also provide some strengthening energy.

But the East China Sea is so big, where can I find them.

Other pirates, eating is equal to not eating.

Even if it's the Black Cat Pirates, the Kree Pirates, eating their enhanced energy is not satisfactory.

Attack on the Navy?

The navy of the East China Sea Division, the strongest commodore or colonel, can solve it when he is fifteen meters long.

There is no value.

This made Xia Qiu very dissatisfied, and at the same time, a certain thought in his heart became stronger and stronger.

Isn't it time to go to the Great Voyage?

In Xia Qiu's heart, the desire to explore and the idea of becoming stronger overrode the fear of the great voyage for the first time.

。。。

"Is this the Great Route?"

Upside Down Mountain, a pirate ship from the West Sea, overturned the Upside Down Mountain and rushed down the waterway.

Bang.

The pirate ship landed heavily on the sea, slowly steady, but small cracks appeared in the hull.

"Finally the Great Voyage, hahaha, let's conquer it." On the deck, a pirate wearing a captain's hat stood up and shouted, "We're going to start here and make the Black Horn Pirates famous." ”

"Roar, roar, roar." The other pirates shouted loudly.

At the stern of the ship, a hooded figure saw this scene, shook his head, and said softly: "You alone can't survive on this route." ”

"I'll help you get to the next town, and then I'll leave you."

"It's time to find the next partner to work with."

The owner of the figure slowly walked back to the cabin and closed the hatch.
