Very Likely the Eternal Night Demon Emperor
The two of them used all sorts of methods before finally stabilizing themselves.
When they were finally able to catch their breath, they quickly looked at each other. For a moment, neither could find a word to say.
"What just happened?! It looked like a person!!"
"It really was a person! I didn't see what he looked like either! Too fast! He was far too fast!!"
The two cried out in astonishment.
Although they had only just broken through to the peak great emperor realm, they still possessed the strength of peak great emperor realm cultivators!
Even with their strength, they had to tread with the utmost care to move around at this depth!
Yet that person had just flown straight down at full speed!
And he didn't seem to be affected at all!
It was outrageous!!!
"Could it be one of those existences at the very top?!" the black-robed middle-aged man asked.
"Impossible! No matter how powerful they are, it would be impossible! Unless it was the demon emperor!" the white-robed middle-aged man said.
"The demon emperor? Isn't he in the Devil Palace? Did he come here?" the black-robed middle-aged man asked.
"That's not the demon emperor I mean! I heard that the deepest this demon emperor could reach was only twenty or thirty li down, so he couldn't possibly fly like that at this depth!" the white-robed middle-aged man said.
"You don't mean the previous demon emperor, the Eternal Night Demon Emperor, do you?!"
"That's right! Before the Eternal Night Demon Emperor even entered the great emperor realm, I heard he could already reach a depth of around twenty li in the Heavenfall Demon Cavern! Just think how deep he could go after breaking through to the great emperor realm and successfully cultivating to its peak?!"
"But hasn't the Eternal Night Demon Emperor been missing for over a thousand years?!"
"Maybe he was in seclusion all that time! And now he's come out?!"
"Could the Eternal Night Demon Emperor have been in seclusion in here this whole time?!!"
The two discussed it heatedly, but the shock in their hearts did not diminish in the slightest.
While the two were deep in their heated discussion, Lu Qing'an continued flying deeper at tremendous speed.
His expression was perfectly calm as he surveyed his surroundings while flying.
"Why are so few people cultivating in the Heavenfall Demon Cavern? And those two peak great emperor realm cultivators didn't look familiar. Did they just break through to the peak great emperor realm? They didn't seem like much either, struggling like that at a depth of only ten li."
Lu Qing'an shook his head.
He had no idea how much the Demon Domain had changed during the thousand years he had been away.
A lot of promising newcomers must have appeared, but they seemed rather ordinary.
A short while later, he reached a depth of twenty li in the Heavenfall Demon Cavern in the blink of an eye.
When he arrived there, he suddenly slowed down.
He had found a mark he had left here back then.
Looking at the mark, he raised the corners of his mouth slightly.
"The mark is still here."
Back then, he had entered this place solely to escape those hunting him down. He hadn't expected that something he possessed would grant him such strong protection against being devoured by the flames.
That was why he had been able to reach this depth without great emperor realm cultivation.
It had been the result of maxed-out luck.
After breaking through to the great emperor realm and cultivating to its peak, gaining the greatest combat strength in the history of the Demon Domain, he had come here once again.
It was on that visit that he had found the materials to forge two treasures.
That place was more than thirty li deep in the Heavenfall Demon Cavern.
That was right. Even at his strongest, he had only been able to reach a depth of thirty li.
Now that he had withdrawn cultivation twice as strong as before, it should be enough for him to reach the deepest part of the Heavenfall Demon Cavern.
If it still wasn't enough, he would withdraw some more cultivation to use.
Three times, four times, even five times!
As long as this world didn't collapse, he would keep withdrawing cultivation until he could reach the deepest part of the Heavenfall Demon Cavern!
"There should be enough Heavenfall Divine Metal at the deepest point. I hope there's at least twice as much as the Heavenfall Divine Metal I obtained on my last visit."
He looked at the mark he had left before for a while, then paid it no further attention and continued flying deeper.
Once again, he became a streak of black light, flying into the depths at tremendous speed.
In the blink of an eye, he had descended another five li.
But just then, he slowed down a little.
He had unexpectedly discovered that there was someone ahead!
Someone actually made it this deep?
He soon discovered how this person had managed to reach such a depth.
So it's formations. Still, this person's attainment in formations is rather astonishing. And it isn't that old fellow I know. A peak great emperor realm expert who rose to prominence during the past thousand-odd years?
He realized he didn't know this person.
After becoming the Eternal Night Demon Emperor and killing all his enemies, he had gone into seclusion to pursue a breakthrough for a period of about ten thousand years.
After making his breakthrough, he had remained active in the Demon Domain for nearly another ten thousand years. In the end, his outlook changed, and he decided to live a settled life, so he quietly left the Demon Domain.
Thus, he knew almost none of the peak great emperor realm experts who weren't from his own generation.
In his eyes, they were all rising talents of the Demon Domain.
There was another possibility: some experts might have entered seclusion or gone into hiding just as he rose to power, and not ventured out for tens of thousands of years.
That was less likely.
And as he remembered it, the strongest formation master in the Demon Domain was still an old friend of his.
Could this person have some connection to that old friend of mine?
He pondered for a moment, then gave the matter no further thought.
His task now was to obtain the Heavenfall Divine Metal quickly and return to his daughters.
So he passed straight by the person and flew rapidly deeper.
At that moment, a young woman stood amid a multitude of formation lights, her flame-red hair cascading down and her white dress fluttering, whiter than snow. She walked slowly through the air toward the deeper reaches of the Heavenfall Demon Cavern.
She kept counting her steps under her breath.
"All right, I've finally reached a depth of twenty-five li! I've surpassed my limits again! Now, I'll practice formations right here!"
Pride showed on her youthful face. She stopped and sat down cross-legged on the spot. Countless formation patterns flowed around her, golden and silver light weaving into a net like the Milky Way falling into the mortal world.
With a light tap of her fingertips, runes fluttered like a swarm of butterflies, every ray of formation light holding the might to shatter mountains and split seas.
But just as she was feeling pleased with herself for making another breakthrough, a flash of black light suddenly streaked past her!
"Hm?!"
She quickly looked ahead.
Because so many formations covered the area around her, she hadn't noticed anything approaching from behind. Only when that "thing" flashed past in front of her and caught her eye did she realize it was actually a person!
"A person?! Impossible!!"
She quickly focused her gaze on the back of the person who had swept past.
Yet in the blink of an eye, that person had vanished at the far edge of her vision!
The terrifying waves of flame had already limited her vision, preventing her from seeing the person clearly!
"It really was a person! But how could anyone fly down like that at this depth?!!"
"Is that even a person?!!!"
She had only been able to reach this depth by relying entirely on her terrifying mastery of formations. If she had relied on cultivation alone, she would have been forced to stop before reaching a depth of twenty li!
Yet the person she had just seen had only a thin layer of Demonic Qi around him, with no other protection whatsoever!!
It was utterly shocking beyond belief!!!
