When he stood in the middle of the plateau, which was being lit by the sun coming from the surface through the tunnel that led to the surface.
Vali looked around and scanned the area because this was the place from where he sensed the biggest and strongest energy signature of the entire subterranean world.
'There is nothing here besides the unnatural magical density... but that doesn't make any sense...'
And just as Vali was lost in his thoughts because he couldn't find any source behind the energy in this place, suddenly an enormous presence descended onto the small plateau out of nowhere, as the devil dragonoid became wary of it...
However, he knew that it was only the lingering spirit of the deceased expert who was killed here and managed to preserve his consciousness and leave it behind.
"Interesting... visitor... most unexpected..."
Vali wasn't sure about the lingering spirit of whatever died here, but he could sense that this was one lingering spirit of the Tier 13 entities that perished here; though he was aware of only one, that didn't mean that there wasn't more of them...
Somewhere... in the end, this entire place was pretty massive and even with his senses, he couldn't convert it entirely in one go.
Vali looked at the lingering spirit with a certain amount of wariness because this could go very wrong if the lingering spirit had any capability to defend him, which was a big unknown for the devil dragonoid of the House Lucifer.
"So what are you? You smell like Fiend but, at the same time, vastly different..."
The lingering spirit was mainly talking to itself, which was neither a good nor bad sign from Vali's point of view... some people could change mood almost instantaneously.
"Devil, apparently we are artificially created species by someone at Tier 13 for the purpose of combining the best area of the Fiends of the Infinite Abyss, Magicians, Arcanists and Cultivators, to give birth to a perfect all-rounder."
Vali answered in the best initiation of his father while omitting some of the more unimportant matters into something that could be called a basic definition of what the devils were.
"I see..."
The lingering spirit stated neutrally as it continued staring at the devil.
"Are you the lingering spirit of one of the Elder Gods who were killed in this place?"
Vali proceeded to ask as he looked at the lingering spirit because it was highly unlikely that it was from the Void Leviathan because the Void Leviathans, despite their overwhelming power, were creatures of very low intelligence and were mostly acting on their instincts.
"Yes..."
This was a relatively expectable result; afterward, Vali was listening to the ramblings of the lingering spirit of the Elder God who was killed here, as that was something that wasn't pleasant for him.
Still, the chatty Elder God occasionally dropped some important information.
After one hour of listening to the annoying lingering spirit of the Elder God, it confirmed Vali's suspicion that this was something akin to an enormous graveyard that was created by some powerful Tier 14 entity that sealed this entire world in the Endless Void.
Normally speaking, it should be virtually impossible even to enter this world, so it was mind blogging how Vali managed to enter or, rather, how the cultists of the Baatorian Pantheon managed to enter this world two thousand years ago.
Considering all things, Vali decided to take everything that was in the subterranean world and that was a lot.
From the ramblings of the lingering spirit, evidently, there were hundreds if not thousands of corpses of Tier 10 entities at minimal and countless of Tier 11, not to mention there were at least 3 Tier 12.
So, that was a huge win for the Empire because these were invaluable resources that could be used for myriads of purposes. Especially the Divine Sparks of the Elder Gods...
Those ones were extremely precious because, from what Vali saw in them, they could be used by Baatorian Gods to advance in their Godhood Index by leaps and bounds.
Even Vali considered becoming a God because it would greatly enhance his strength and at the same time, with the amount of resources that were here, it would be just drop in the enormous see if he took some Divine Sparks or other materials that were from the remains of the Elder Gods.
'I could reach Paramount God in a century or so if I use Divine Spark of Tier 11 Elder God together with the collective resources of the Baator.'
Vali thought as he ignored the lingering spirit that was shouting all around and focused on collecting the corpses, valuables and other things in the enormous subterranean world while also calculating the shortest time to advance into the Paramount God with the available resources.
He knew that the Godhood Method that the Gods of the Baatorian Pantheon were using was, in truth, based on the Elder Gods, as it was imitating them to the last part.
It took Vali an entire one day to completely clear out the subterranean world because even though it wasn't that big compared to the standards of the Endless Void, it was still big enough and he needed to proceed carefully when in this place.
At some point, he was even forced to summon the power of his father when he was approaching the remains of then Tier 12 entities and even some of the stronger Tier 11 as the remnants of their power was still too strong and could hurt him severely if he was not careful.
"And with this, it should be done..."
He stated to himself while storing away the last corpse, which belonged to Tier 11 dwarf and with this, the entire place was cleared and he obtained a lot of his trip.
Now that this was done, he needed to check on the last place in which he couldn't see with his senses located in something known as the Bermuda Triangle.
