The sea here was very deep. After diving thousands of fathoms below, the surroundings were already enveloped in darkness. Apart from the background noise, there was no other sound in the ocean; even the roaring above the sea had been completely overshadowed by the sound of the waves.
The darkness and dead silence felt like a bloodthirsty maw below, waiting to devour everything above.
When they dove below ten thousand fathoms, the surface of the deep blue bubble enveloping them started to display layers of ripples. The bubble quivered, rotated, and diminished the overwhelming pressure.
"Not so fast, the Demon God Tomb is at least ten thousand fathoms below the seabed. At this depth, it can deter the vast majority of cultivators."
An accident here could mean instant death by crushing pressure.
Yu Ziqing could clearly sense that the Gui Water Qi outside was diminishing, while the Ren Water Qi was increasing. Drops of deep blue seawater gathered among the ordinary seawater. With just a gentle stir, the undercurrent was extremely evident.
"That is the most typical One Element Heavy Water. A single drop weighs a hundred pounds. Under the deep sea pressure, over time, the Ren Water Qi and Gui Water Qi converge to slowly form this treasure. It's rare outside, but here it is ubiquitous."
Yang explained, stressing and cautioning Yu Ziqing.
"Don't be reckless, don't take it. The balance here is fragile. If you cause a ripple in the One Element Heavy Water, my Deep Sea Water Avoidance Technique won't hold, and your Golden Water Yin Escape might not withstand it either. As for Lou Huai, he would be suppressed to death even without a physical body."
Yang maneuvered the water bubble, carefully evading the One Element Heavy Water along the way, continuing the descent.
Upon sensing the presence of the seabed and looking down, they even found a faint glow, seeing a layer of black water lying on the seabed, as if there was another ocean below, and this was only the surface.
"We're here. Let me remind you again, don't be reckless, especially with that layer of black seawater at the seabed. Don't touch it."
The bubble hovered ten fathoms above the seabed, slowly drifting laterally for several miles, until a dim, blue light lit up a small area ahead.
A grand group of sunken palaces quietly stood there.
Several anglerfish, each dozens of fathoms long, floated silently. The dim blue light that illuminated the area came from the lanterns on their heads.
The anglerfish seemed to sense something, slowly turning around, and the dim blue light gradually illuminated the area, a deep blue bubble quietly floating there.
"Don't move, don't bother, Lou Huai, let out a bit of your Devil's aura."
Lou Huai stood still, burped, and a wisp of black Qi slowly seeped out of the deep blue bubble.
As the trace of demonic Qi dispersed, the anglerfish, sensing the Qi, had their skin disintegrate silently, leaving behind a skeleton emitting Death Qi, quietly floating there.
They slowly turned back, maintaining their original position, illuminating the palace group and its surroundings.
The bubble drifted silently towards the palace group, without encountering any obstruction.
Yu Ziqing glanced back, shaking his head secretly. With the deeds of the infamous Evil Dragon, how could there still be living beings around its mausoleum?
Those deep-sea anglerfish no longer had any flesh or blood, seemingly dead but still being exploited by the Evil Dragon to serve as street lamps here.
The bubble, following the main hall entrance, drifted slowly into the dark space inside.
The next moment, the surrounding environment changed suddenly, as candlelight illuminated a wide road. On both sides stood skeletons of different sea demons, holding Ten Thousand Year Lamps and illuminating everything nearby.
There was no trace of seawater here. Ahead stood stone pillars like a forest, each towering into the sky, supporting the Sky Dome. Above the Sky Dome, it mirrored the ocean surface, flowing quietly in the sky.
"This is his mausoleum. He imitated the sages by forcibly refining a Deserted Cave Heaven into his palace to serve as a mausoleum, but it's only a superficial mimicry.
The ancient sages chose a Cave Heaven for a mausoleum to avoid affecting future generations, as some among them were too powerful.
So powerful that even when their life-force ceased, their consciousness wouldn't disperse. Some sages were so strong they couldn't even bury themselves, having to seal themselves in a Cave Heaven.
If they were buried outside, the Death Qi they produced after death could turn thousands of miles into a barren land."
Yang remarked at the sight before him.
Yu Ziqing naturally thought of Heavenly Monarch Luoge, even after so many years of death, he could still awaken.
Even in slumber, the Death Qi he exuded didn't lose control but danced around him, elevating his corpse, parading through the Mausoleum Cave Heaven.
Hearing Yang's words now, Yu Ziqing realized that Heavenly Monarch Luoge must have been immensely powerful in life.
So strong that the power dispersed from him after death remained under control, and his residual consciousness passively influenced the Death Qi.
Had Heavenly Monarch Luoge's Death Qi naturally dissipated, Sorrow Cave Heaven would have long become a pure death domain.
