Underground sea...

In a deserted sea area...

Chu Xingyun pinched his fingers with both hands and shot a series of energy into the stone slab in front of him.

As the ninety-nine eighty-one seals penetrated into the stone slab, the next moment... a series of deep red lights gushed out from the huge stone slab.

The crimson light quickly condensed in the air and gradually condensed into a huge blood-light vortex that was as scattered as blood...

Looking at the huge spiral nest that was extremely shrill, as if it was gathered from dirty blood, Chu Xingyun knew that this was the entrance to the Netherworld Sea.

Chu Xingyun put away the stone slab with a sudden hand, then jumped into the blood-colored vortex.

As the light and shadow in front of him rotated, when Chu Xingyun recovered his vision again, he had already appeared in an extremely unfamiliar sea area.

Originally, in Chu Xingyun's imagination, since the so-called Netherworld Sea was within the center of the earth, it would have to be a narrow, low, and very dim underwater world.

But after truly entering the Netherworld Sea, everything here subverted all Chu Xingyun's cognition.

The area of ​​the Netherworld Sea is extremely huge, which is as much larger than any sea in the four seas.

Moreover, the Netherworld Sea is not only not dark, but also very bright.

Looking around, the sea water in the Netherworld is extremely pure and so clean that it makes people intoxicated by the purification of the earth.

Like the surface world, there is also a huge light source in the Netherworld.

The difference is that the light source in the surface world is an extremely huge sun hanging high in the sky.

The light source in the Netherworld Sea comes from the center of the earth, from a huge lava ball that emits infinite light and heat!

The ancient world, the overall shape is like an egg.

If the surface world is the shell of an egg.

Then the earthly world where the Nether Sea is located is the egg yolk!

Before entering the Netherworld Sea, Chu Xingyun thought that the so-called Netherworld Sea is just a deep water located underground.

But in fact, this is not the case.

If the four seas on the surface of the world are water traces hanging on the outer layer of egg shells.

Then the Nether Sea in the central world is a water mark hanging on the inner layer of the egg shell.

The huge Netherworld Sea is actually flowing against the inner wall of the earth's center world.

Standing on an island in the Netherworld Sea, Chu Xingyun's head was not facing the surface, but vertically facing the ground, towards the center of the earth.

And at the center of the earth is an extremely huge lava sphere.

Different from the surface world...

There is no alternation of day and night in the Netherworld.

Three hundred and sixty-five days a year, twelve hours a day.

In the Netherworld, there is daytime, but no night.

Looking around, the huge lava ball constantly radiates endless heat, evaporating a large amount of sea water in the Netherworld Sea, forming thick dark clouds, covering the entire Netherworld Sea.

There is never a sunny day in the dark sea during the heavy rain.

The most terrifying thing is that it is smoked by melt balls day and night, and the temperature in the Netherworld Sea is very high.

Especially the dark clouds in the air, after absorbing enough heat, the rain falling down was extremely hot.

If it were ordinary lives, they would not be able to survive here at all. I am afraid that they would be cooked as soon as they came in.

But of course Chu Xingyun didn't have this problem. Not to mention the water vapor of hundreds of degrees, even if it was thousands of degrees, it would not hurt him.

Looking at the extremely harsh environment in the Netherworld Sea, Chu Xingyun smiled bitterly in addition to laughing bitterly.

Originally, Chu Xingyun thought that the Netherworld Sea had never been opened, so... there should be many strange creatures here.

But reality tells Chu Xingyun that although such an environment is not impossible to survive, it is definitely not suitable for cubs of any organism to grow here.

Those extremely weak and fragile biological cubs may have been cooked by the high temperature here as soon as they were born, and there was no chance of growing.

Therefore, in the Netherworld Sea, there is a dead sea of ​​silence, and here... there is no sign of life.

However, despite knowing this, Chu Xingyun still began to patrol in the Netherworld Sea with a hint of luxury, trying to find a trace of life.

Unfortunately, Chu Xingyun never found any signs of life while searching along the way.

However, although there was no sign of life here, what excited Chu Xingyun was that he found a specialty in the Nether Sea - the Earth Center Railway!

This earth-centered iron is the most special. It is a strange metal formed by the lava spheres that fall into the netherworld sea when the earth-centered lava spheres erupt regularly.

Looking at the mountain-stacked earth-centered iron under the sea, Chu Xingyun suddenly felt energetic.

I didn't bother to find any signs of life, so I started to dig in large quantities and looted a large amount of earth-centered railway.

Some people may say, what is the difference between the so-called earth-centered iron and the specialty of the South China Sea, the red flame iron erupted by active volcanoes?

Is the so-called volcanic eruption not the eruption of the earth's center lava?

Of course not, in fact... what the volcano erupts is the magma in the lava layer in the mantle.

But this huge lava giant ball in the Nether Sea is the core of the earth!

After collecting a large amount of geocentric iron, the geocentric iron ore at the bottom of the sea was nowhere to be found.

Chu Xingyun had to stop temporarily and stopped collecting the so-called earth-centered iron.

Anyway, this Netherworld Sea belongs entirely to Chu Xingyun alone, so it doesn’t matter where these earth-centered irons are piled up.

In the following time, Chu Xingyun continued to travel around the Netherworld Sea and thoroughly explored the terrain here.

The Nether Sea is located between the mantle and the core, but it does not completely enclose the core.

The Nether Black Pole and the inner side of the mantle occupy one-third of the total area on the inner side of the mantle.

In other words, there are actually two-thirds of the areas between the mantle and the core, which are connected to each other.

Only one-third of the area has a mezzanine, and the so-called Netherworld Sea is within this mezzanine.

After more than three years, Chu Xingyun finally patrols the entire Nether Sea.

In the center of the Netherworld Sea, Chu Xingyun discovered a golden crystal mountain.

Seeing this crystal mountain, Chu Xingyun immediately burst into laughter.

At the foot of this crystal mountain, what suppresses the sea eye of the Netherworld Sea.

Through this sea eye, you can appear in the four sea eyes at any time, east, west, south, north, and four sea eyes.

As for the reverse direction, from the four majors in the east, west, south, north and north to enter the Netherworld Sea, it depends on whether Chu Xingyun opens this entrance.

Next, Chu Xingyun stayed at the foot of the golden crystal mountain and used the crystals on the mountain to refine the Netherworld Sea Dragon Palace!

These crystals are the best things to seal, and are the innate wonders condensed when the Great Dao seals the Netherworld Sea.

The Four Seas Dragon Palaces are also built with similar innate objects.

Billions of years ago, when the dragon clan had not yet become the supreme tribe of all races, in fact, the four seas were all sealed with a crystal mountain.

Among them, the East China Sea is blue, the North China Sea is black, the South China Sea is red, and the West China Sea is white.

As for the Netherworld Sea, it is naturally the golden crystal mountain located in the center.

The main force was in front of the golden crystal mountain. Chu Xingyun sacrificed his soul and hung it above his head, saying a loud voice: "In my name, establish the Dragon Palace in the Nether Sea - Qi!"

Accompanied by Chu Xingyun's voice, strange runes came out of Chu Xingyun's soul's mouth, falling into the golden crystal mountain.
