The moment Leon locked onto the glowing spirit herbs growing on the seafloor, his eyes beamed with wonder
'This quality… they're Tier-5 Spirit Herbs…!' he mentally exclaimed.
He brought himself closer and inspected each stalk of spirit herb before a blueish-green flower that glowed brighter than the others caught his attention.
'This is… a Tier-6 Divine Herb…!'
Leon wanted to suck in a deep breath after discovering a Tier-6 Divine Herb, but he couldn't breathe underwater, nor could he hold his breath for too long.
'I need some air,' his eyes flickered.
He summoned a Nihility Barrier around himself in the next moment and dispersed all the seawater into countless strands of energy for him to absorb, including air.
Swish!
However, Leon underestimated just how terrifying the water pressure could be.
With such a mass body of seawater pressing down on his Nihility Barrier, the quantity of seawater getting reduced into energy reached an unprecedented level!
Strands of True Grandmist Energy, among multiple other types of energy like dark, life, wood, water, earth, and spirit, flooded into his body.
Any average person would have immediately exploded from absorbing excessive amounts of energy, but his Black Vortex Space devoured everything with a bottomless appetite.
Within several moments, he had already accumulated hundreds of wisps of True Grandmist Energy!
His present speed of accumulating True Grandmist Energy was easily tens of times faster than when he was digging through the land in the western region!
"What a pleasant discovery. I didn't expect this at all," Leon exclaimed.
With this kind of accumulation speed, he had sharply cut down the required time for gathering the True Grandmist Energy he needed!
Nevertheless, Leon did not lose himself in the moment.
He connected himself to the realm spirit's omniscience and surveyed the sea level of the Bone Sea on the surface.
Even though the Bone Sea was losing large quantities of seawater to him right at that moment, there were hardly any changes in the sea level.
The Boundless Sea from outside quickly filled up missing bodies of water in the Bone Sea via the river channels!
After several dozens of breaths, Leon's accumulation of True Grandmist Energy had reached the thousands of wisps!
If he could, he wanted to keep going until his Black Vortex Space fattened up to the brim!
Alas, it didn't take long before the Peak Arch Demon-level Sea Monsters in the bottom region of the Bone Sea finally paid attention to his presence—or rather, it was the presence of True Grandmist Energy that caught their attention.
They didn't understand what it was, but they were subconsciously drawn to it—as if their instincts were telling them that the True Grandmist Energy could help them evolve into higher-level beings.
Nevertheless, Leon decisively dispersed his Nihility Barrier and absorbed every last wisp of True Grandmist Energy into his body.
When the only source of Peak Arch Demon-level Sea Monsters' attraction disappeared, they halted their advance and resumed their idle life in the depth of the Bone Sea.
'It looks like these sea monsters aren't very intelligent,' Leon assumed while studying a Peak Arch Demon-level octopus.
'Beasts and demons at this level would have already awakened their spiritual intelligence, but these sea monsters are different. Despite living for so long, it seemed their intelligence had degraded instead.'
At least, that was what he felt, but he couldn't be too sure.
It was as if the Peak Arch Demon-level Sea Monsters were no longer capable of thought and moved solely on its most basic instincts to live.
Another way of looking at it is that the Peak Arch Demon-level Sea Monsters were operating in power-saving modes to expend the least about of their energy.
'Are they nearing the ends of their lifespans?' Leon wondered.
If it was true, there might be chances for him to obtain their blood essences without fighting them for it.
However, he couldn't be so sure if the blood essences of a sea monster that died of natural causes would still be useful or not.
After all, there shouldn't be any lifeforce left if the sea monster's lifespan expires.
'What if these Peak Arch Demon-level Sea Monsters' lifespan has already expired, but the Black Turtle God Beast's vibrant lifeforce is keeping them alive, hence their zombie-like state?' Leon speculated.
He could see that traces of the Black Turtle God Beast's blood flowed out from the nine giant pillars impaled in the seafloor.
Thanks to the Black Turtle God Beast's blood, all the vegetation he sees on the seafloor flourished.
He swam over to the foot of a pillar and collected some samples of the bloodsoaked sand before extracting a few drops of the Black Turtle God Beast's blood from it and storing most of them in a glass bottle.
Given the Peak Arch Demon-level Sea Monsters' attraction to the True Grandmist Energy, he couldn't use the Black Turtle God Beast's blood to temper his flesh with it.
He would most likely end up in one of the Peak Arch Demon-level Sea Monster's bellies if he attempted to do so.
'I'll just refine this drop of Black Turtle God Beast blood for my Everlasting Blood Mantra,' he decided on the last drop of blood he didn't store away.
A few moments later, he finished infusing the refined product, the Black Turtle Origin Blood, into his bloodstream.
Leon's eyes flickered after sensing his body's changes.
It was just a single drop of Black Turtle Origin Blood, but he felt like his lifespan extended by a few hundred years.
At the same time, his regeneration ability improved further.
'How potent…' he was astonished by the result.
'However, I shouldn't just focus on the Black Turtle God Beast's blood; this entire place is a holy land of healing medicine.'
Leon shifted his attention back to the plethora of spirit herbs on the seafloor.
'Although these Tier-5 Spirit Herbs are mainly all spirit herbs with healing properties, if I can refine them into Tier-5 recovery pills, I will no longer have to worry about anyone losing their limbs,' he mused.
If he uses the Tier-6 Divine Herb, he could even help Mia regrow her missing organ.
