Whether on Heavenly Nether Star or in other cultivation worlds, any living being that comes into contact with spiritual energy and immortality can develop intelligence. Heavenly Nether Star was once home to a hundred races, including humans, as well as other races such as Demon Clan and Winged Clan. However, most of those races were isolated from the continent where humans lived and did not live together.
However, the only race capable of rivaling the human race is the Demon Clan.
It is said that the progenitor of the Demon Clan was the demon beast, a race that emerged from the reproduction and evolution of the demon beast and possesses the same intelligence as humans. In the cultivation world, the Demon Clan is generally a mysterious existence because the continent they live on has scarce spiritual energy, and they always want to enter the human continent to plunder spiritual energy and resources, so humans and Demon Clan often go to war.
Gu Chen had entered the alternate-dimensional battlefield between the Demon Clan and the human race more than once, and fought and fought with them. Therefore, given his status and knowledge at the time, he had seen more than one or two different races!
Now, Gu Chen is looking at the corpses in the dungeon, his expression shifting.
He was certain that this was not Demon Clan, even though he had never seen Demon Clan in person before! Demon Clan were extremely tall, while this corpse was only about a meter tall. Even if it had shrunk due to being a corpse, it still couldn't be smaller than a human.
Moreover, the Demon Clan does not have such a fleshy tumor on their heads. This thing seems to be some kind of sensory object, which is very peculiar.
Lost in thought, Gu Chen's hand unconsciously rested on the iron bars of the dungeon. But the moment he touched them, he felt as if struck by lightning, his entire body trembling!
"Taiyi Crystal!"
Gu Chen let out a scream and quickly pulled his hand away, utterly horrified!
If he wasn't mistaken, the iron bars of the dungeon used to imprison the alien race were actually made of Taiyi Crystal!
The world's treasures are divided into nine grades!
Taiyi Crystal belongs to the eighth grade!
Legend has it that Taiyi Crystal can amplify spells and neutralize their effects.
In the world of cultivation, the outer wall of the Heavenly Pivot Sect's mountain-guarding formation, which Gu Chen forged back then, was made of Taiyi Crystal!
This stone is as black and shiny as obsidian. However, even if he is the sect leader, he does not have many Taiyi Crystal, because even on Heavenly Nether Star, the number of such rare treasures is too small, and it is not easy to collect them.
But now, he actually saw Taiyi Crystal in this Small Thousand World belonging to the Dharma-ending Age of Earth, and they were even being used to build dungeons! They were piled up like pillars, extremely extravagant!
Gu Chen refused to believe it and went to check out the other dungeons. They were all the same; all the materials were identical!
These dungeon bars, reflecting a chilling light, are all crafted from Taiyi Crystal!
What kind of monster could build a dungeon using such a thing? And what race are these strange people he imprisoned? Where do they come from? Are they the native inhabitants of the Land of Heaven and Earth?
Gu Chen walked forward. In each dungeon, there was a dead corpse lying on the ground. Without exception, they were all short and small, and each had a fleshy growth like a bean sprout protruding from their forehead.
The more Gu Chen looked, the more alarmed he became, his thoughts racing and in utter chaos. He counted over a hundred dungeons in the entire cave. That meant over a hundred alien races were imprisoned there!
Finally, Gu Chen reached the end. When the firelight illuminated the wall at the end of the cave, a huge beast head totem appeared in Gu Chen's field of vision.
The beast head that suddenly appeared was fierce and wild, with lifelike eyes that seemed to be devouring people. Gu Chen's chest trembled violently at the sight, and he couldn't help but take a few steps back.
How bizarre! So bizarre!
After regaining his composure, Gu Chen looked at the mural and felt as if the solitary beast head had come alive just a moment ago. The immense mental impact almost made him lose his footing.
Gu Chen didn't recognize what kind of monster was depicted in the painting, but just from the aura it exuded, he knew that this ferocious beast was no ordinary creature; it was at least a high-level demon beast comparable to dragons and phoenixes.
Unbeknownst to him, Gu Chen's vest was already soaked with cold sweat as he walked. He couldn't find anything in this dungeon, and with his abilities, he couldn't break through the iron bars forged from Taiyi Crystal for the time being.
Just as Gu Chen was about to walk back the way he came, he saw a line of small characters beneath the huge beast head.
"I have been hunting down the Ao Clan for over 10,600 years, but unexpectedly, I have lost my way back. It is fate and destiny; I have no one to blame but myself. This dungeon is sealed off; it is inhabited by the most heinous Ao Clan. Those who come after may leave on their own..."
Towards the end, the handwriting began to fade and became so blurry that it was no longer legible.
If he wasn't mistaken, Gu Chen immediately recognized that the image of himself in this picture and the image of himself on the stone tablet outside were written by the same person!
The Ao Clan, over 16,000 years old!
If this person isn't exaggerating, then he should at least be at the level of an immortal! He might even be more powerful than in his previous life! After all, Divine Emperor is just a title, and only at the Tribulation Transcendence Stage stage. Only by successfully transcending the tribulation can one become Earth Immortal on Heavenly Nether Star!
This person is clearly an immortal!
Given his status, it's no wonder he could use Taiyi Crystal as dungeon bars. A cultivator at this level wouldn't care about something as mere level eight!
However, this was the first time Gu Chen had heard of the term "Ao Clan." Why was this powerful being hunting down the Ao Clan? And instead of killing them, why was he imprisoning them?
Furthermore, given that powerful being's abilities, he couldn't have disappeared without a trace. Even if he couldn't find the way back to his previous world, where has he gone now?
Moreover, a thought arose in Gu Chen's mind: Could it be that his master Luo Yunxi, the Luo God, came to this place because of the Ao Clan?!
But why, after so many years on Heavenly Nether Star, has he rarely heard of the name "Ao Clan"?
"This is truly full of doubts." Gu Chen frowned, stroking the text beneath the beast head. Unlike the murderous aura on the stone tablet, it seemed as if he had casually scribbled it there, then stopped writing halfway through.
This senior is truly incredibly carefree.
Gu Chen gave a wry smile, but he was already certain that if the origin of this Land of Heaven and Earth was not created by this powerful being, then it must be related to him. Or perhaps, the so-called Ao Clan were the original inhabitants. In short, all of this was like a thick fog shrouding Gu Chen's eyes, and he would not get an answer unless the clouds parted and the sun shone through.
Gu Chen also understood why his Divine Sense couldn't probe too far. There were Taiyi Crystal Taiyi Crystal everywhere here, and with his cultivation and attainments, it would be too easy for him to be imprisoned by them.
"I never expected to see an immortal-level senior here, someone I'd never even seen on Heavenly Nether Star, after my tribulation," Gu Chen shook his head, his eyes resolute. "However, this must be inextricably linked to my master's guidance. I must investigate this thoroughly."
Just as Gu Chen was about to leave, a voice suddenly rang out.
"Help me... help me..."
Each cry, like those of the underworld, or more like the cawing of crows clinging to ghost trees in the dead of night, echoed throughout the dungeon.
