After slowly adapting to the underwater world, Ding Hao felt that this place seemed to be not much different from the land world, the most intuitive feeling was as if the air had been replaced by seawater, the terrain on the undersea below was undulating, the pale black plants were floating back and forth, and some strange sea creatures were swimming and shuttling, and the stars were shining like stars.

Ding Hao's problem has flareed up again.

Fortunately, the surface of the seabed is going all the way down, and the general direction should not be wrong.

About an hour later.

"It's strange, according to my speed, at least I have penetrated nearly a million kilometers into the Seven Seas, and the depth is almost 20,000 meters, but why have I not encountered those powerful abyss demons along the way, nor have there been any signs of Sea Clan activities, is the Seven Seas really vast, and the area I have entered is only the periphery?"

Ding Hao was a little puzzled.

His divine sense had been radiating all the time, observing the surroundings and seeing everything within a radius of nearly a thousand miles, but he didn't even find the slightest thing.

If this continues, when will we find the Sea Clan?

Just when Ding Hao felt that his exploration was a bit reckless, should he change his approach, his divine sense fed back, and behind an imperceptible valley in front of him, a building similar to an undersea city suddenly appeared, and he was overjoyed in his heart, and immediately sped up.

In the next moment, Ding Hao came to this place.

"Sure enough, it's a sea tribe city......" Ding Hao glanced at it, and was immediately overjoyed.

But soon, he realized that something was wrong.

The city seems a little empty.

The divine sense swept carefully, and the expression on Ding Hao's face was a little weird.

This small city in front of you can probably be compared to the million-person settlement of the terrestrial human race, the shape of the building is a little strange, most of them are imitated by the appearance of some sea beasts and sea monsters, quite a little bit of the color of the underwater fairy tale world, a towering spiral stone tower is located in the center of the city, and it is also filled with a faint breath of the five elements of power elements, Ding Hao's pupil technique sweeped, and he knew that this stone tower was built by suppressing the terrain and sea water and some other environments within a radius of hundreds of miles, which can make the city not invaded by ocean currents and not destroyed by the movement of the earth's crust！

Compared to the Terrans, the cities of the Sea Tribes are still slightly different.

The division of some functional areas, Ding Hao couldn't figure it out for a while.

Of course, none of this is the point.

The key is that after Ding Hao entered this city, after some observation, it can be determined that this is not an ancient ruins or a decaying city, but a brand new city, from all signs and signs, less than a month or two ago, there were still millions of sea tribe creatures living here, but about dozens of days ago, they completely abandoned here, as if fleeing, leaving this city they don't know how long they have survived.

Judging from the layout of the city and other aspects, Ding Hao couldn't tell which line of the sea clan this city belonged to, but at least it wasn't the mermaid clan.

Why did they suddenly abandon their homeland?

It's like hiding from some kind of disaster!

The problem is that there is not the slightest sign of damage in the entire city, and there is no trace of fighting, which shows that it was not an invasion by a foreign enemy, and it was not a flight because of the war.

Ding Hao couldn't understand.

He searched the city and found little to no avail.

He originally wanted to find something similar to a book or a map, but who knew that the city had been completely emptied, leaving nothing useful, and the writing of the Sea Clan was obviously different from that of the mainland creatures, obscure, and even the two old monsters, Sword Ancestor and Sword Ancestor, could not do anything.

Ding Hao didn't stay in the city for too long and continued to move forward.

About an hour later, more than 100,000 nautical miles away, he came across another Sea Clan city.

This sea clan city is more magnificent than the previous one, surrounded by inscription formations to protect it, its buildings are continuous like deep forest mountains, the statues of gods are towering, magnificent and majestic to the extreme, you can see the existence of the sea clan army camp, but it is still empty, there is not even a sea clan creature in it, the core position of all formations has been removed, some dull low-level sea beasts and fish, swimming in the city!

"It seems to be hiding from something, it should be an orderly evacuation, not a deserted escape!"

Ding Hao rubbed his temples, such a discovery was a little incomprehensible.

He suddenly felt that the sea seemed to be enveloped by an invisible aura, and the atmosphere was a little weird.

With a flash of light, Ding Hao realized that it was not only the emptiness of the city, but also that he had not encountered any other ocean abyss monsters except for the octopus monster along the way—not even some slightly more ferocious sea beasts, which was a bit unreasonable.

The sea area that Ding Hao walked through was already extremely vast, but along the way, all he saw were weak low-level sea beasts and fish, these creatures were like ants and insects on land, and they didn't even have the most basic wisdom.

Could it be that some danger is coming here?

So the Sea Clan creatures who are a little stronger or have a certain amount of wisdom have already left here in advance?

Ding Hao was thoughtful.

He didn't stop and kept going.

In the next half a day, he successively encountered dozens of cities of the Sea Clan, of different sizes, several of which had excellent geographical locations, the terrain contained great opportunities, there were underground dragon veins gathering, and the aura in the sea water was much more abundant than other places, and from the perspective of architectural style and age, it is very likely that it has been inherited for thousands of years.

But these cities, without exception, have been abandoned in this way.

Ding Hao felt more and more solemn.

You must know that the power of the Sea Clan is not weaker than that of the land creatures, the Seven Seas are divided into seven royal clans, and the power of each clan can fight against the top land races such as the Divine Court and the Feather Clan, and the huge population base makes the Sea Clan strong come out in large numbers, and the number of strong people in the Divine Realm is not a few, this is a very powerful race, what kind of disaster is it, what kind of disaster actually makes them so willing to abandon the city where their ancestral home has lived for thousands of years, and retreat like this?

An invisible danger made Ding Hao feel depressed.

By the second day, he had traversed at least millions of miles, and still found no trace of the Sea Tribe—except for the cities that had been abandoned and abandoned.

What is going on among the Sea Clan?

I don't know if it's the mental effect, or the intuition of [Shengzi Jue] that made Ding Hao have some kind of premonition, and gradually he can also feel that between heaven and earth, there is an indescribable killing force.

This kind of killing power, this is not the crushing of some kind of power, nor is it the coercion brought by a certain strong person, but a real murderous aura of heaven and earth!

In the martial arts world, there are three types of murderous aura-

Kill!

Ground kill!

!

People kill the machine, the world repeats!

The ground is killed, and the dragon and snake are on the land!

Heaven kills, moving stars and changing houses!

If it was a real heaven and earth killing machine, then even the immortals would tremble.

According to the legend of the Endless Continent, since the chaos of heaven and earth first opened the world and the stars were nourished and nourished, the heaven and earth killing machine only appeared once, that was at the end of the immortal ancient era, the heaven and earth sent a killing machine, as a result, countless immortals fell, the gods died and fell asleep, the six realms collapsed, the reincarnation was not obvious, and the immortal ancient giants passed away one after another......

Not a catastrophe.

Countless earth-shattering existences could not escape this heaven and earth killing machine, and finally fell.

That heaven and earth killing machine changed the world.

The prosperity of the Immortal Gu Era was gone, and the Six Realms collapsed, and the order of this world was chaotic.

Just once, there were such horrific consequences.

If you do it again......

As long as Ding Hao thought about it, he shuddered a little.

But now, in this ocean, he faintly felt a hint of heaven and earth killing.

As soon as he thought of this, he seemed to understand a little bit why the Sea Clan would choose so much, and even did not hesitate to give up the ancient city of the ancestral era, in the face of the Heaven and Earth Killing Machine, they were indeed unable to resist - not to mention the Sea Clan, even if all the living beings in the Divine Grace Continent joined forces, they would not be able to fight against the power of this heaven and earth!

That's when —

Rumble!

Thundered!

A series of roars came from afar.

Then the ground trembled violently, and the calm water suddenly became chaotic and turbid, and about ten miles away, in the dark sea water, suddenly a crimson light rose to the sky, shining around like daylight, and the sea fish and low-level sea beasts seemed to feel the danger, and swam wildly, and some of them rushed directly into the flames in a panic, turning into ashes......

"That's magma...... An undersea volcano erupts!"

Ding Hao instantly distinguished.

The temperature of the surrounding sea water rose sharply, and it became hot in the blink of an eye, and a large number of low-level sea beasts and fish struggled to die screaming at this moment, they were used to the cold environment of the seabed, they could not survive in such high temperatures at all, and they were cooked in an instant.

"Meow, do you want to eat a few and try it?" The Evil Moon Great Demon King was a little hesitant, he hadn't eaten such natural boiled seafood yet.

Ding Hao ignored this cute thing, his mind moved, and the yin and yang Pisces Tuan behind him flashed, and the next moment he came to the release of the red flames, and at a glance, the whole person was suddenly taken aback.

Everywhere I looked, there was a sea of red magma, boiling magma erupted from under the surface, staining half of the seawater, and the temperature of the hesitating sea water was too high to cool the magma, and everywhere was like a sea of fire......

It's horrible!

Because less than a quarter of an hour ago, Ding Hao's divine sense had scanned this place, and at that time it was still a heavy rocky mountain range!

In an instant, it turned into a sea of magma and fire.

Ding Hao stood thousands of meters away from the ground, only to see the crimson magma sea expanding and spreading wildly, and within a few dozen breaths, there was no rock below that had not yet melted, and an abandoned city in the distance was swallowed up by this boundless sea of fire in an instant.
