It is important to know that the "inner sea" does not mean that the Earth's interior is completely hollow, it is actually an underground cavity located in the upper mantle layer.

If I have to describe it, it is like a newspaper crumpled into a ball, filled with a lot of wrinkles and gaps, which are filled with seawater.

This kind of folds and voids are layered on top of each other, and a large number of planes can be used by the "god-made race" to cultivate the underwater oasis, but this kind of underground cavity is huge and a little beyond imagination.

The place where they drove Sun Island into the inner sea was actually located at the junction of the earth's crust and the upper mantle layer, and had not really penetrated into the depths of the inner sea.

The merfolk were lucky enough to escape into the patio and successfully escape to the surface world.

Thanks to the underwater oasis where they live, it is not far from the patio.

It is estimated that the vast majority of the "god-made races" do not know where to connect to the patio, and the probability of finding the patio is similar to finding a well on the surface of the earth that does not know where it is located.

After all, the chaotic undercurrent and chaotic gravity environment near the patio are not suitable for living creatures, and they will be swept into it and crushed if they are not careful.

If it weren't for the fact that the mermaids were not chasing and killing the enemy, they rushed into the Tongtianjing in a panic, trying to take advantage of the harsh environment in the Tongtianjing to get rid of the pursuers.

Maybe you really don't dare to have the courage to take the initiative to find the ethereal "heaven" described in the prophecy of the ancestors, which is ethereal and does not know whether it exists.

Manipulating Sun Island slowly left the gravity chaos area of the Tongtianjing, and flew or floated towards the depths of the Eternal Sea, looking for a relatively calm body of water, and began to test whether human players were suitable for survival here.

The result is very surprising, it is clear that it is the location of the deep mantle layer, but the pressure is not as terrible as imagined.

If the body strength is equivalent to the average limit of the human body, if it is directly exposed to the seawater outside the sun island mask, although it is difficult to move freely, and staying too long can cause serious injury.

However, after wearing the [Aquaman's Forest] suit, this effect is directly eliminated, and it is no different from operating in the deep sea of the surface ocean.

This means that human players can be summoned to fight each other in the Sea of Eternal Sleep, thus avoiding damage to the Overworld.

To Eryi's surprise, on the way to reconnoiter the Eternal Sleeping Sea, he actually found piles of collapsed rock ruins on the "seabed", and from its regular section, it can be clearly seen that it has been artificially processed, rather than a naturally spalled rock mass.

After inquiry, I learned that those were all left over the remnants of the race that had died out in the war for living space over the years, or were destroyed by the attack of the giant beasts.

Although theoretically speaking, the ultimate goal of a war for living space is to seize the opponent's Sun Island, and generally will not be willing to ruthlessly destroy the opponent's Sun Island.

And with both sides having an amazingly defended Sun Island, it is difficult to really cause devastating damage to the Sun Island, otherwise the Sun Island would not be called a shelter.

Of course, there are no absolutes, once a real fire is started, if you use the energy weapons on Sun Island to carry out unlimited bombardment, it is still possible to completely exhaust the energy core of Sun Island, causing Sun Island to sink.

In the same way, some overly powerful giant beasts, once they launch a crazy collision with Sun Island, the impact force exceeds the upper limit of the protective light shield of Sun Island, and it is also possible to cause the light mask to disappear and be destroyed.

And these rocky ruins left on the bottom of the sea are obviously the ruins of Sun Island that have been damaged under various circumstances.

But after some "archaeological excavations" of these ruins, they found that the core of Sun Island, that is, the diamond-shaped pyramid called the Temple of the Sun, is often not destroyed, and most of them are very well preserved.

And not all of the scattered Sun Island regional modules collapsed, most of them were just scattered because they lost the traction of the core.

Interestingly, the size of the modules in the area that relies on the core traction is not static, if necessary, it can be put together piece by piece like building blocks, even if the carrying limit of the core is reached, it can also be connected by connecting more cores to improve the gravitational force!

So the question is, can the core that has been depleted and extinguished be repaired? The answer is: Yes!

After a period of research that completely controlled a floating prism tower, a total of thirteen floating prism towers were scattered in the surface ocean, that is, the cores of the thirteen sun islands, most of which were well preserved.

And the energy core itself has a variety of automatic charging functions,

Therefore, it only needs to be reactivated with a huge amount of energy, and the energy drain function of the energy core can be reactivated.

Once activated, the energy core itself will continue to draw energy from the void to recover.

Coincidentally, Er Yi had a lot of elemental jade brought back from the Endless Plane in his hands!

Either way, as long as you can continuously and steadily supply energy to the energy cores, you can activate these sleeping cores!

And when it comes to Eryi, even elemental jade is not used, and Sun Island itself is a huge energy source.

Just find those extinguished cores, splice them to Sun Island and inject half of the energy, and you can activate them in no time!

Once the core is activated, it will immediately automatically absorb those scattered area modules, even if it is incomplete, it can be pieced together like a puzzle, and then after appropriate adjustments, a complete new Sun Island is born!

As for the original Sun Island, there is no need to worry about the impact of losing half of its energy.

Because the energy core of Sun Island itself has an extremely large energy storage scale, the speed of drawing energy from the void is also extremely fast.

Otherwise, how do you think it can tow a huge island-like module, dive, float and lift up at will, and still maintain its own operation and protective shield all the time?

Therefore, after half of the energy is separated, it will not affect its own operation, and it will not even take long to fill up again.

The daily operation and the consumption of the protective shield are just the energy dissipation caused by its full energy, as long as the instantaneous consumption does not exceed its energy storage limit, its energy is almost unlimited!

As a result, after they entered the Sea of Eternal Sleep, the other "god-made races" had not yet encountered them, and the scale of the Sun Island under them became larger and larger, and finally it looked like a continent floating in the underground ocean!
