The furious lightning struck straight down, its power so immense that even a high-grade immortal would not dare to face it directly.
But at this moment, a dense black mist surged upwards like a gale, then slammed head-on into the lightning!
The lightning could not penetrate the black mist and exploded violently in mid-air.
At the same time, Wu Tian also suffered a considerable impact.
His body trembled slightly, and he spat out a mouthful of fresh blood!
"Wu Tian!"
This sudden turn of events stunned everyone.
Lei Qianjiao instinctively cried out, intending to jump down to help.
"Don't come over!"
But at this moment, Wu Tian sharply stopped her.
Wu Tian wiped the blood from the corner of his mouth and looked forward.
In mid-air, black mist converged from all directions.
For a time, an extremely terrifying pressure enveloped the heavens and earth.
Everyone was horrified to discover that the immortal energy within their bodies was being strongly suppressed.
They could barely move their bodies!
The black mist gathered, eventually forming a figure.
The figure floated silently in the air, shrouded from head to toe in a black robe, appearing extremely mysterious.
It clearly looked quite gaunt, yet it exuded an aura of extreme, terrifying destruction.
It seemed as if with a mere wave of its hand, the entire world would be annihilated…
Everyone felt a genuine sense of fear.
For them, such a figure should only appear in their deepest nightmares.
Yet, it had appeared in reality…
What was going on?
Facing this indescribably terrifying figure, Wu Tian showed no fear.
His eyes were dark, yet a smile flickered across his face, and his voice was somewhat hoarse as he said:
"You're finally willing to come out, aren't you?"
Hearing Wu Tian's words, everyone was even more astonished.
What did he mean? Had Wu Tian discovered the existence of this figure from the beginning?
The black-robed figure turned, facing Wu Tian.
Its black robe billowed without wind, and its hood was pitch black, revealing nothing but two points of eerie green light, exuding a strange and mysterious aura.
It spoke in a deep voice, "Such keen perception. I didn't expect you to discover my existence."
"But it makes no difference whether you discover me or not. In the end, I will act, and you will only have the choice between dying quickly or dying slowly."
The black-robed figure's words made everyone feel as if their hearts were being fiercely gripped.
Two questions arose in their minds simultaneously.
Who was this person?
Why did it speak like this?
Wu Tian's expression remained solemn throughout.
It seemed that even he felt a profound sense of dread towards this black-robed figure.
He spoke, "What level of demonic creature are you?"
"After so many years, why are you still not dead?"
The black-robed figure let out a cold laugh and said, "Dead? What a joke!"
"I am the immortal and indestructible Corpse Heaven Demon Emperor, one of the Twelve Demon Emperors. How could I perish in a place like this?"
"Humans, you overestimate your abilities far too much."
The voice of the Corpse Heaven Demon Emperor struck those present who understood demonic creatures with immense shock.
For some with weaker wills, their legs turned to jelly, and they collapsed to the ground!
At this moment, Wu Tian's pupils also dilated sharply, and even half of his body felt numb.
A sense of impending doom churned violently above his head like a vortex.
For a moment, he felt dizzy, almost unable to stand steady.
He never dreamed that he would encounter a Demon Emperor here!
It was said that Demon Emperors possessed power comparable to Immortal Kings. Who could possibly contend with such an existence?
Wu Tian felt a tingling sensation on his scalp.
He stared with wide eyes, desperately controlling the trembling of his body, and said:
"No, you… how can you be here?"
"Weren't the demonic creatures almost wiped out? As a Demon Emperor, you shouldn't have been missed!"
He was truly panicking now.
After all, facing an opponent of a Demon Emperor's caliber, let alone self-detonation, even if everyone in the Sacred Lightning Hall detonated themselves, they wouldn't be able to harm it in the slightest.
His mind was now a complete blank, and he had no idea what to do.
The Corpse Heaven Demon Emperor sensed his nervousness and chuckled lightly, saying:
"Why am I here?"
"The reason is simple. It was I who led the demon army to attack this Thunder God Immortal Realm back then."
"Even the one you revere as the Thunder God perished by my hand."
"So, is it truly that strange for me to appear here?"
The Corpse Heaven Demon Emperor's words naturally stirred up a storm.
While not everyone here knew about demonic creatures, they certainly knew of the Thunder God.
Yet, the Corpse Heaven Demon Emperor claimed the Thunder God died by its hand.
The terrifying strength of the Corpse Heaven Demon Emperor was self-evident.
Wu Tian froze for a moment, unable to accept the Corpse Heaven Demon Emperor's words.
However, he soon sensed something was amiss, and stared at the Corpse Heaven Demon Emperor, saying:
"No, you're lying to me. This matter is definitely not as simple as you claim."
"Your current state is still very weak, which means you didn't gain any advantage from the Thunder God."
"Furthermore, if things were truly as you say, why would you still be lingering here after all these years?"
"As a dignified Demon Emperor, you wouldn't lack the ability to break through spatial restrictions, would you?"
The Corpse Heaven Demon Emperor was silent for a moment, then laughed again.
It nodded and said:
"Indeed, you are very clever. However, I do not like your cleverness."
With that, the Corpse Heaven Demon Emperor waved its hand, and a stream of black energy shot out like a ferocious python, directly towards Wu Tian.
Seeing this, Wu Tian's expression changed drastically!
He gathered almost all his immortal energy and used the Thunderclap Sword to forcefully block the attack!
However, even so, Wu Tian was sent flying back over a hundred meters. He barely managed to stabilize himself, his hands trembling uncontrollably.
This situation deepened his sense of horror.
With such casual ease, this Corpse Heaven Demon Emperor could unleash such terrifying energy.
Who could possibly resist it?
The Corpse Heaven Demon Emperor shook its head, saying with a hint of regret:
"It seems my power has indeed been greatly weakened."
"Otherwise, a minuscule insect like you would have long since turned to ash."
