"This is… teleportation? When did you master Spatial Law? No, this wasn't your doing," Duna muttered with surprise and wonder.
"It's the realm spirit's ability. Though, I did feed it 10-thousand wisps of True Grandmist Energy to restore this ability," Leon explained before his gaze sharpened in the next instant.
"More importantly, we have company."
Their sudden appearance in the new sea region quickly attracted the nearby Low-rank Arch Demon-level sea monsters.
Swoosh—!
Leon and Duna could sense the large movements of water in the dark depths of the Bone Sea, which provided zero visibility to the eye.
However, neither of them had any trouble seeing the Low-rank Arch Demon-level sea monsters in their surroundings.
Duna could see the shape of their souls overlapping with their enormous bodies.
On the other hand, Leon sensed them with his all-encompassing divine sense, and if that isn't enough, he still had the realm spirit's omniscience to rely on.
The Low-rank Arch Demon-level sea monsters weren't as massive as the Peak-rank Arch Demon-level sea monsters at the bottom of Bone Sea.
Even so, their bodies were still massive, nonetheless, easily a hundredfold over humans.
However, with a single Banshee Scream, the Low-rank Arch Demon-level sea monsters squirmed and shook their heads with pain before swimming away.
"We came to kill them, not shoo them away," Leon reminded with a wry smile.
"Hmph, we can do the killing later. I wasn't done talking to you yet," Duna replied with a snort.
"How did you know the realm spirit is the Eternal Night Demon Empress's daughter? Why does she listen to you? Did you hook up with her?" she interrogated before adding with a grumpy tone, "I guess you do have a fetish for spirits."
Leon gaped, feeling at a loss for words.
Duna suddenly pulled him close and looked him directly in the eye before spouting domineeringly, "I may not be the only p*ssy you have, but I'll definitely be the only spirit you can have."
After hearing that, Leon gaped even more widely before Duna suddenly took the chance to press her lips against his.
Alas, he was forced to separate himself from her shortly while coughing after some seawater entered his system.
He summoned another Nihility Barrier and took the chance to recover.
"What an overbearing ghost you are," Leon spouted wryly while coughing up the seawater and gasping for air. "Are you trying to kill me?"
"Heh, not a bad idea. We can both be ghosts together," Duna snickered.
Leon could not help but shake his head helplessly before explaining with a sigh, "There are two realm spirits; the original and the Eternal Night Demon Emperor's daughter."
"The original realm spirit takes on a male form, and it was the one who reached out to me after I tore a hole in it—"
"You even swing that way?"
Duna gasped with an exaggerated look of disbelief, causing Leon's expression to stiffen with a dark look of distress.
"Hahaha, I'm joking. Loosen up, man," Duna patted him on the back from within his Nihility Barrier, completely amused with his distressed look.
Leon could only smile ruefully in response.
"Absorb the True Grandmist Energy while you still can," he said with a sigh.
He absorbed all the other types of energy in the refined seawater, leaving only the True Grandmist Energy for her to absorb.
At the same time, the Low-rank Arch Demon-level sea monsters returned in groups, attracted by the True Grandmist Energy's existence.
"From what I've discovered earlier, True Grandmist Energy attracts the sea monsters," he informed her.
"Of course," Duna affirmed with a look of certainty.
"Even if they are beings with low intelligence, they can still understand the extraordinariness of True Grandmist Energy with their basic instincts."
"Hmph, I've scared them off, yet they still have the gall to come for something that belongs to me!" she snorted.
Shortly after, Duna shot towards the Low-rank Arch Demon-level sea monsters after Leon created an opening in his Nihility Barrier to leave.
Just as she was about to get swallowed whole by a Red-horned Whale, her Banshee Cry made the Low-rank Arch Demon-level Red-horned Whale turn its head away.
Then, Duna took the opportunity to latch onto its giant head, bite at its flesh, and slowly devour its huge soul.
The Red-horned Whale squirmed in resistance, but it could not shake Duna off its head with its great strength—or rather, it couldn't make use of its great strength to shake her off.
It was considerably weakened after having its soul caught by Duna.
A short while later, the Red-horned Whale's soul was utterly devoured, stripped away from its body, which was left to float soullessly in the depth of the Bone Sea.
Duna quickly parted from it and shot to her next target.
At the same time, a group of Arch Demon-level sea monsters rushed over to devour the soulless Red-horn Whale's flesh while others targeted Duna and Leon's True Grandmist Energy.
However, Leon simply let Duna use her Banshee Scream to deal with them while he continued producing True Grandmist Energy and watching her fight.
Her soul-devouring art seemed powerful, overbearing, and somewhat evil, making him wonder where she learned it.
But considering her devil soul fragment was further awakened, it wouldn't be strange if it came from there.
As Duna devoured more souls, the Arch Demon-level sea monsters' corpses attracted more Arch Demon-level sea monsters to them.
"Hm?"
Leon narrowed his eyes on a sea monster's half-eaten corpse, which revealed its bones and inner organs, but more importantly, its red sea monster core.
"Artificial spirit energy?" Leon immediately determined the source of energy within the sea monster core.
Suddenly, many things about sea monsters became apparent to him.
For instance, their mutated appearance, level of intelligence, monstrous size, and powerful strength were all caused by artificial spirit energy.
"Does every sea monster in the Bone Sea have artificial spirit energy cores like this?" Leon furrowed his brows in wonder.
"I haven't discovered artificial spirit energy towers or power sources in the secret realm… so the sea monsters could only have formed these artificial spirit energy cores in the Boundless Sea…"
