The convenience of the waterfall current can only last to a position of three or four thousand meters, and if you continue to follow, you will be strangled by the turbulent current!

And the biggest difference between the sea in this world and the sea in Ziggy's impression, in addition to the inexplicable sea building stone factor, is the difference in oxygen concentration in the deep sea.

The sea on the earth, because of the lack of sunlight and no plants in the deep sea, the oxygen concentration is extremely low, and it can only support some small creatures, but in the great channel of this world, the oxygen in the deep sea is more abundant, which makes the deep sea inhabited by many giant sea beasts and sea kings!

Compared with the sea kings, there are also some sea beasts that are very huge.

Especially in the deep sea, there are many giant sea beasts, but their IQs are generally much higher than those of the sea kings - of course, this refers to the ordinary sea kings outside of the seven.

After leaving the Great Falls Current, the Red was surrounded by many huge sea beasts, no less in size than ordinary sea kings.

When several cadres stood on the boats in all directions to escort the Red, Shanks walked up to the "bull's head" in the bow of the ship, sat down casually, and poured himself a bowl of wine with a gourd......

"Ladies and gentlemen, we are just passing by, please make a convenient ...... Please! Shanks said, and the overlord's domineering spirit completely dissipated, and at the same time drank the wine in the bowl, and then slammed it on the bow of the boat.

Suddenly, the surrounding sea beasts gradually dispersed and disappeared into darkness again.

And it didn't take long for hordes of sea kings to gather.

Compared with the two, the appearance of the deep-sea sea beast is more fierce and hideous, but it does not have the sense of disobedience of the sea kings - the sea kings are like ordinary land animals and birds, which have been extremely gigantic, and have more organs to survive in the water.

In addition, because the sea kings only "have a lot of food in the deep sea oxygen-rich environment and are suitable for survival", rather than "can only survive in the deep sea", their vision is generally normal, and they are not like giant sea beasts that can only survive in the deep sea, and most of them can only adapt to the pressure of the deep sea and their vision is degraded.

Of course, there are also sea beasts that can adapt to multi-level pressure, not only can go to shallow seas, but their eyesight has not deteriorated, but the number is scarce.

In the oxygen-rich environment of 4,000 meters deep in the sea, there are many giant sea beasts and sea kings, and even the survival density of sea kings alone is not smaller than that of the windless zone.

Of course, the average depth of the ocean is also four or five thousand meters, and the sea water in other places is not as deep as here, only the center of the Red Earth Continent, where Mary Joya is located, there is a 10,000-meter deep sea......

Ziggy called some sea kings to come over to escort him, and suddenly there were no more sea beasts to harass him.

At first, it looked like an orangutan, but it had light-emitting organs like "lanternfish" on the top of its head.

This made the crew see a lot of amazing scenes along the way.

"It's so convenient...... With Ziggy, not only will you never get lost in the sea, but also in the deep sea and in windless zones, you can have a sea king escort. Lachiru sighed from the side.

"Well, Ziggy should be the world's No. 1 'navigator'!" Gennosuke also said on the side.

"Nope." Ziegy shook his head at this point, and then grinned at his companion who looked at him in bewilderment: "It's not a navigator, it's a navigator...... Hahaha. ”

Seeing Ziggy start to boast, Morio and the others laughed again and began to sarcastic.

Ziggy's "Navigator" progresses, and the ascension rate at this time is also extremely fast......

In terms of the improvement of the progress of the role, it is much faster to sail in the great passages than in the four seas, which convinces Ziggy that navigators must face the vagaries of nature!

And when sailing in the windless zone, it is faster to ascend than when sailing in the great waterway, which makes Ziggy understand - navigators, and more importantly, to reach the destination!

From the G6 branch to the Chambord Islands, the difficulties and obstacles from nature are fixed along the way, and how to arrive safely is the mission of the "navigator".

Deliberately choosing a difficult route will not be more conducive to playing, spending months, going through all kinds of extreme weather, and spending more than a month, under the relay pull of the Sea King, from the windless belt, the two get no different progress, and the latter is more efficient.

From this, Ziggy can summarize the key points of the play: to confront nature, to revere nature, to control the fury of nature, and at the same time, there is no sense of banter.

Now diving 10,000 meters to the bottom of the sea, from the perspective of the difficulty of the route, I am afraid that it is comparable to walking around the first half of the entire great channel, and the progress of the play obtained is naturally amazing......

And for Ziggy, the efficiency of navigation is the most important thing, and in this world, especially in the great waterways, the last thing to worry about is the role of "navigator"!

The goal is to dive 10,000 meters, but even if there is a sea king escort, it is by no means as simple as "driving ten kilometers", and you still have to choose the route.

Submarine volcanoes, submarine stone forests, submarine whirlpools...... What should be avoided is still to be avoided, and because Fish-Man Island is the only gap under the Red Earth Continent, theoretically six or seven kilometers directly above Fish-Man Island is the Red Earth Continent, and it is necessary to present a certain angle to pass through the gap to Fish-Man Island.

After a full day, the light could be seen again in the distance.

"Here we are." Ziggy saw Fish-Man Island, which was not familiar but very impressive.

Ziggy had only been here once, and had only stayed for three days, most of which he was still unconscious.

The whole Fish-Man Island looks like a huge "bubble", the lower part of the bubble is also filled with seawater, and the upper part is the incredible air environment.

Although Ziggy is not a real fish-man, as a member of the Sun Pirates, he understands that this is the most comfortable environment for fish-people - they are usually in the air, and they can jump into the water at any time.

Even the underwater part of the building is wrapped in bubbles on the windows and doors, and the room is an ordinary air space, and the outside is seawater.

The Fish-People, and more importantly "people" rather than "fish", believe that the Fish-People should be soaked in water all day, and even should live at the bottom of the sea, is completely racially biased.

Living on Fish-Man Island now is not voluntary by the Fish-Man Clan......

On Fish-Man Island, there are also "tree roots" that stretch from the top, which are the root system of the sun tree Eve, which conducts sunlight into Fish-Man Island, so that the surrounding area can be "sunny" during the day.

It's just that......

In Ziggy's few memories of Fish-Man Island, the sun transmitted from the bottom of the sea is not very comfortable, far less than the real sun.

"It's amazing!"

"There is such a place at the bottom of the sea......"

"Is this the hometown of Fei Ge and the apprentice?"

"I haven't been here!" Jack looked like he was choking, and then added angrily: "What a small place, huh." ”

Ziggy had known for a long time that he was a half-fish man who was out there.

"I've only been here once, and I haven't done a good job." Ziggy shrugged his shoulders, calculating how long he had been on Fish-Man Island, Shanks who hadn't been here with the Roger Pirates before, stayed here for a long time!

In fact, if you think about it, you can analyze that Ziggy is a slave rescued by Tiger from Mary Joa, but now Ziggy, although he will not go around shouting that he was a slave before, he will not deliberately avoid it.

Around Fish-Man Island, there are many giant sea beasts living there, but even the brainless sea kings usually do not attack Fish-Man Island, but have become part of the geographical advantages of Fish-Man Island.
