Beneath the deep Arctic sea, an incomparably large eye continues to gush out undercurrents that are much hotter than the Arctic Ocean, which may be one of the main reasons for the rapid melting of the Arctic ice.

The requisitioned Sun Island, against the gushing undercurrent, is slowly sinking into the depths of the sea eye.

From time to time, you can see the fragmented corpses of huge sea beasts, driven by the crazy swirling and stirring water, squirting towards the surface ocean above, and I don't know how many of them will survive alive in the end.

A variety of ancient marine organisms that have long been extinct can enrich the diversity of marine life to a certain extent.

However, the emergence of these ancient sea overlords will inevitably cause chaos in the ecosystem and the extinction of various modern marine life.

At the same time, they themselves may not be able to adapt to the natural environment of the modern ocean for a long time, and they do not know what kind of changes they will eventually bring to the nature of the earth.

The sea eye leading to the ground is very deep, and the slow sinking of Sun Island gives people an endless sense of falling, as if they are falling into hell but they can't fall to the bottom, if you have deep sea phobia or claustrophobia, I am afraid that it will be very uncomfortable in this environment.

The process of passing through the "patio" of Sun Island is very slow.

It's not that it can only move so slowly, it's that there is a chaotic gravity environment and an undercurrent like a meat grinder in the patio.

The slightest mistake will cause Sun Island to directly crash into the surrounding rock walls, and even if it is protected by a protective light shield, the bumps caused will definitely be much worse than seasickness.

It's no wonder that the merfolk leaders say that their venture into the wells and their migration to the surface ocean is a matter of unknown dangers.

Because no one knows if it will succeed at all, if it weren't for the fact that the war in the Eternal Sea is too cruel, it is estimated that no one would choose to take this risk of death.

Fortunately, as the only means of transportation that can pass through the patio, Sun Island's multi-force structure can well offset the chaotic gravity environment in the patio, and at the same time, the strong and sturdy protective light shield isolates the damage of the undercurrent.

The only thing that makes people a little uncomfortable is that the annular shape of the atomic structure of Sun Island is attracted by gravity, like a crazy spinning Rubik's Cube, which makes people dare not look up at the surroundings at all, and it is estimated that they will be shaken by the picture of the sky spinning at a glance.

Even if it was as powerful as Eryi and the incarnation of consciousness, they couldn't help but feel nauseous, and when Sun Island finally passed through the patio safely and returned to a flat state, they still brewed for a long time before they eased up.

"This is the Inland Sea?"

Eryi pressed the stomach of the pantothenic acid water, and looked up at the "sky" top-heavy.

I was surprised to find that the dark "sky dome" was actually inlaid with shining "stars".

But soon he reacted, no, what they see now is not the "sky" but the underground!

If the Earth were to be seen as a ping-pong ball filled with water, they would now be hanging upside down on the inner wall of the sphere like bats.

But the strange gravity of the earth makes them not feel that they are facing down, just as people on the surface do not feel that they are hanging upside down because of the rotation of the earth.

And the shining "stars" in the "sky" are not galaxies in the universe, but sun islands floating in the inner sea!

The light mask shrouded in the outer layer of Sun Island shone like a small sun, illuminating a small area of pitch-black environment around it, although the brightness was not very strong, but it was definitely dazzling for the pitch-black and dull environment of the inner sea.

The most peculiar thing is that the existence of Sun Island seems to have become the source of life in the earth's inland sea, just as the sun is to the earth.

These sun islands are usually suspended near the inner wall of the earth, illuminating a large area below, and in this light-shrouded area, various seagrasses and seaweeds grow at an alarming rate, forming a dense underwater forest.

These undersea forests become oases that attract fish, creating a "pasture" for grazing fish.

However, this kind of underwater oasis overgrown with various seaweeds and seaweeds often attracts large groups of herbivorous fish, and the gathering of herbivorous fish often attracts carnivorous fish.

These "god-made races" have survived in the inland seas for countless years, and are physically and ecologically closer to fish...... Including mermaids, the breeding offspring are all spawning, and the scale of fish spawning can be imagined.

Therefore, although the area of Sun Island is not small, it is a complex frame structure with multiple layers.

But the "God-made race" with amazing reproductive ability is simply not something that a single sun island can accommodate.

Therefore, the lower classes and adult individuals in the group can only relocate from Sun Island to the underwater oasis attached to Sun Island to support themselves, and only use Sun Island as a breeding ground and refuge.

And a random attack by a giant beast is likely to cause the death of millions of individuals of the race.

This is also the reason why the fecundity is so amazing, and they have the wisdom to know how to protect their offspring, and there is a shelter like Sun Island that can protect the larvae, resulting in the "god-made race" with an amazing survival rate of the larvae, and the reason why the inner sea of the earth is completely filled with individual races.

And in order to avoid such large-scale casualties, and also to improve the reproduction ability of the race, it is inevitable that they will begin to covet the Sun Island of other races.

It is worth mentioning that the mermaid clan is already a "minority" among the "god-created races", which is difficult to breed and has a sparse population.

But this mermaid group, which was only subdued by Eryi, has a population of more than 10 million!

That's it, according to the merfolk leader, they were first attacked by giant beasts, and then attacked by another "god-made race".

had to give up the undersea oasis that the tribe had cultivated for many years, and abandoned all the clansmen who lived in the oasis, just the result of the high-level tribe taking the hatchlings that had not yet fully reached adulthood, starting the Sun Island adventure and escaping into the Tongtianjing, and almost being wiped out.

One can imagine how huge the merfolk were before this catastrophe!

When they learned about this situation, they couldn't imagine it!

The 7.5 billion people of the surface civilization already make them feel that the population has exploded.

So how many people can be nurtured in a three-dimensional ocean space that is several times larger than the surface ocean?
