The Petrified Turtle was diving silently and rapidly, leaving the storm raging above the sea behind. The images from the external monitors were converted into several large holographic projections, which formed an immersive scene, as if the heavy armor around the bridge had disappeared, and everyone could directly experience the feeling of being immersed in the deep sea.

The sea surface above gradually receded, and soon only some vague flashes could be seen coming from above, which was Ai'ou's endless lightning storm illuminating this storm-ridden planet: in the past, the sirens of this planet, after arriving in the "air world," first came into contact with lightning, and they didn't recognize "sunlight" until more than a thousand years after Ivinna observed the starry sky.

It's a pity that these historical details have been submerged in Ai'ou's turbulent waves, and it's probably difficult for anyone to know them again.

As the diving depth increased, the turbulence of the water flow began to calm down, and those raging waves seemed to be isolated in another world. The darkness pressed in more and more intensely from all directions, but along with the darkness came a strange sense of security. Lily hugged her shoulders and jumped around beside Hao Ren: "Awoo, my deep-sea phobia is being triggered..."

Vivian slapped her to the side: "Stop it, your brain can't get such a complicated disease."

"The deeper we dive, the calmer it becomes..." Shakira coiled at the front of the bridge, staring blankly at the deep darkness outside, "When did our ancestors first swim up from the deep sea? Why did they think of leaving the safe and peaceful seabed? What did they feel when they first saw the storm on the sea surface? Was it novelty and surprise? Or fear and anxiety?"

"Races with history can touch the trajectory of their ancestors from their own history books, but even if we return to our homeland, we can only rely on guesswork to imagine how we once lived here," the Siren Queen shook her head, "I have no joy in returning here, only emptiness."

"Perhaps you'll feel better after seeing the deep-sea ruins. I think those ruins should be similar to the scenery of Nasaton," Vivian looked at the Siren Queen, with some emotion in her eyes, "To be honest, you are stronger than other aliens on the surface, at least you still try to maintain your culture and think about where you came from. Those guys on the surface don't care about these things at all. For more than ten thousand years, everyone has lived like a bunch of wild animals."

Hao Ren looked at Vivian with a strange expression: "Vivian, is it really okay for you to always use a map cannon against your own compatriots?"

Vivian folded her arms: "Can't I, as an elder, hate those disappointing guys for not living up to expectations?"

Hao Ren was speechless and could only turn his head to order the terminal: "Leave a probe every kilometer we dive. We can't come for nothing. We need to do some ecological research on this planet."

A launch channel opened at the top of the Petrified Turtle, and a small probe rushed out of it, leaving a glimmer of light in the dark deep sea. At this time, the spaceship (perhaps it's more appropriate to call it a submarine?) had sunk into completely dark waters. Except for the lights on the ship, there was no trace of light here, but the ship's external monitors were not based on optics, so the darkness here did not affect everyone's observation of the outside. After continuing to sink for a distance, some strange-shaped animals began to appear in the water. Some were as slender as fish, while others resembled some kind of triangular insect covered with heavy armor. These native creatures had lived here quietly for many years, but now they were suddenly disturbed by a silver-white monster from outer space, and they all scattered in terror. However, some small aquatic animals with great courage approached and gently bumped against the armor of the Petrified Turtle, probably thinking it was edible?

Nangong Wuyue widened her eyes as she looked at the scenery outside, and her tail swayed unconsciously: "I want... to swim around for a while."

The Siren Queen and the other two were also piqued by her interest. Soma happily raised the tip of her tail: "Ooh, that's a good idea! Maybe soaking in the water of our hometown will feel different!"

Hao Ren tested the water quality here and confirmed that no toxic substances had been added here in the changes over the past ten thousand years, so he agreed to the four sirens' diving request. An auxiliary channel opened on the side of the Petrified Turtle, and four slender and graceful figures quickly rushed out of it.

Nangong Wuyue happily spun around in the water, dragging her long tail around in front of the spaceship. The other three sirens curiously chased the strange deep-sea creatures in the surrounding sea water. The faint light emitted by the Petrified Turtle illuminated the graceful figures of these water elves, creating a wonderful scene like something out of a fairy tale. Hao Ren turned on the communicator on the bridge, and Nangong Wuyue's cheerful voice came: "Hey! Landlord, landlord, these hard-shelled animals are gnawing on the numbers on the spaceship~~"

"Don't swim too far, be careful of getting lost and not being able to return," Hao Ren smiled, "Katrina, how do you feel now?"

The Siren Queen's voice then came: "This water... is incredible, with a wonderful sense of intimacy. I don't know how to describe it to you, but only sirens can feel that there is magic here, it's so good!"

Shakira darted down for a distance, then turned around and waved vigorously at the spaceship: "Light! There's light below! It looks like we're almost at the bottom of the sea!"

The Petrified Turtle made an extremely slight hum and began to accelerate its descent. A blurry halo quickly appeared below the spaceship.

What appeared in the halo was a vast expanse of artificial ruins.

On the flat and vast deep-sea beach, the endless siren buildings stretched to the end of the line of sight. They were of varying heights and distributed in an orderly manner. They were built of some kind of white and light green artificial material, and their shapes were like various shells and corals stacked in various forms, elegant, delicate, and full of inexplicable mystery. And the shimmering lights between these buildings were not lights, but a large number of luminous algae - these algae grew luxuriantly in the crevices of those buildings that had been abandoned for more than ten thousand years, emitting a soft and mysterious pale blue and pale pink glow, illuminating the entire city and even the entire seabed away from the darkness.

More than ten thousand years after the sirens' artificial lights went out, the primitive light from nature re-illuminated this deep sea.

This was an ancient kingdom hidden in the deep sea, and its endless territory almost covered the rocky outer layer of the entire planet, while above the kingdom was a thick layer of seawater with an average thickness of more than ten kilometers. The scale of this deep-sea kingdom far exceeded the descriptions in many fairy tales and myths, so that Hao Ren didn't know how to describe this place for a while.

He only knew that when looking at this planet from above Ai'ou, no one would have thought that such a lost kingdom was hidden beneath the endless storms and gray-blue ocean.

"According to the records in the Nasaton database, this should be the siren capital in those years," the data terminal compared the data, "Ivaduran. It looks like the portal opened in this place."

"The energy environment is very chaotic," Hao Ren turned on the radar and found that he could only vaguely sense a large energy vortex nearby, but all the details were interfered with by a strong background noise, "The two worlds should have interfered with each other. The radar's condition is very bad here. It's almost sleepwalking between two worlds."

The data terminal helped operate other equipment: "It should be nearby. Start the conventional feed wave radar, along with optical observation. The vortex is so big, it won't be too difficult to find."

"Let's go help find it too," the Siren Queen's voice came from the communicator, "Don't worry, we'll return immediately if we encounter any situation, and we won't be reckless."

The four sirens swam in four directions into the depths of Ivaduran (the ancient deep-sea capital), while the Petrified Turtle also began to search slowly. The portal seriously interfered with the natural laws of this place, and this distortion involved the origin of the world, so even if Hao Ren was driving a super-advanced spaceship, he didn't dare to mess around.

"Actually, I can also help explore..." Vivian muttered to herself.

Lily looked at her in surprise: "Wow, bat, can your little bats swim now?"

Hao Ren curled his lips: "Can't you two stay quietly in your chairs for a while?"

At this time, Nangong Sanba suddenly saw something on the holographic projection and shouted: "Wait a minute! Look ahead, what is that?!"

The holographic projection immediately zoomed in on the picture, and a huge, dark, strange creation appeared in front of everyone.

Hao Ren widened his eyes: "This is... a spaceship?"
