With Wu Tian's strength, condensing the Heaven-Shattering Demon-Slaying Sword was an extremely difficult feat.
However, since he had succeeded, the power of this peerless divine ability was enough to slay true Golden Immortals.
Shi Tian Demon Emperor was merely a wisp of consciousness at this moment.
Coupled with the suppression from the Thunder God Immortal Realm's energy, he had no ability to resist.
The lightning longsword pierced his brow, and a shrill scream echoed in the consciousness space.
The green flames in Shi Tian Demon Emperor's eyes suddenly blazed!
"Today is your death day! Die for me!"
Wu Tian roared again, then pushed with all his might, and the Heaven-Shattering Demon-Slaying Sword immediately pierced through Shi Tian Demon Emperor's head!
Instantly, a crack spread down from Shi Tian Demon Emperor's forehead, splitting him in two!
"To think that I, a dignified Demon Emperor, would die at your hands!"
"I am not reconciled! I am not reconciled!!!"
Shi Tian Demon Emperor's voice, filled with unwillingness, reverberated throughout the consciousness space.
Following that, with a violent explosion, Shi Tian Demon Emperor's head shattered!
Fragments of black bone rapidly dissipated.
This also signified that the supposedly immortal Shi Tian Demon Emperor had been completely annihilated by Wu Tian!
"Finally, I've dealt with him..."
Seeing this, Wu Tian couldn't help but breathe a sigh of relief.
He had never dreamed that a Demon Emperor would die at his hands.
If this were to spread, it would likely shock the Eight Divine Sects and the Demon Slaying Palace.
Next, Wu Tian no longer focused his attention on Shi Tian Demon Emperor.
With Shi Tian Demon Emperor dead, nothing could stop him from absorbing the demonic energy.
He returned to the sea of consciousness, suspended in the void in a cross-legged meditation, and began to absorb the demonic energy.
After losing Shi Tian Demon Emperor's control, the demonic energy transformed into pure energy.
Under Wu Tian's guidance, it all poured into his body.
The thunder patterns on his skin lit up again, alleviating much of his pressure.
Thus, Wu Tian forgot about time and diligently refined the demonic energy.
Quietly, his cultivation, which had been at the Lower Grade Immortal level, began to skyrocket at an incredible speed...
"It seems he's alright now."
In the outside world, seeing Wu Tian's skin return to normal, Thunder God finally breathed a sigh of relief.
Upon hearing Thunder God's words, Lei Qianjiao's hanging heart finally settled.
She asked Thunder God, "Lord Thunder God, how much longer will he need to absorb it?"
Thunder God shook his head and said, "I'm not sure either."
"However, although he possesses the Heavenly Thunder Body, his foundation is still shallow."
"Therefore, it's impossible for him to absorb all the demonic energy in one go."
"Now, we can only see how much he can absorb this time."
As he spoke, a faint sadness appeared in Thunder God's eyes:
"However, my time is running out. I truly hope he can show me results soon."
Hearing this, Lei Qianjiao was stunned, then her eyes widened as she exclaimed:
"Time is running out? Lord Thunder God, what do you mean by that?"
Thunder God gave a wry smile and said, "Little girl, haven't you noticed that my energy form is becoming weaker and weaker?"
Lei Qianjiao looked at Thunder God's body and suddenly realized.
Compared to before, Thunder God's body had become much more ethereal, almost transparent.
Thunder God continued, "As you know, the reason I can still stand here is that I merged my primordial spirit with the Thunder God Immortal Realm back then."
"In other words, I am sustained by the Thunder God Immortal Realm."
"But if something happens to the Thunder God Immortal Realm, I will also disappear."
"The energy of the Thunder God Immortal Realm has been almost completely drained."
"In at most half a month, it will completely collapse."
"So, I only have half a month left."
"How could this be..." Lei Qianjiao was shocked.
Regardless, Thunder God was her ancestor, and he had given her such great fortune. She naturally did not want Thunder God to disappear like this.
She hurriedly asked, "Is there any way to save you?"
"A way?" Thunder God was slightly taken aback, then he smiled wryly and shook his head, "Wu Tian also asked this question, but it's impossible now."
"I am merely a dead person. Seeing you all now, I am already very content."
"As for resurrection, I have never even thought about it."
"From now on, you just need to cultivate diligently. Don't worry about such trivial matters."
Lei Qianjiao fell silent.
As a girl, her emotions were naturally more sensitive.
Now that she heard Thunder God was about to disappear completely, she felt immense sadness.
Thunder God saw her mood, patted her head, and smiled, "Alright, alright, little girl, don't be sad for me."
"Before I disappear, to be able to make a final contribution to this world, I am already very satisfied."
"Instead of worrying about me, it's better to look at Wu Tian."
"A young man like him will eventually become someone who surpasses me."
Upon hearing this, Lei Qianjiao's eyes immediately flickered with surprise.
Thunder God actually said that Wu Tian would achieve such great things in the future?
Such an evaluation would likely not be given by anyone else.
Thinking of this, Lei Qianjiao couldn't help but look at Wu Tian.
She had already witnessed too many miracles from Wu Tian.
Perhaps, as Thunder God said, his power would be indispensable in this world in the future?
As Wu Tian's cultivation progressed, time slowly passed.
Wu Tian's aura became increasingly powerful. No one knew how much demonic energy he had absorbed.
And after half a month, the aura that had been condensed around Wu Tian suddenly erupted like steam!
Sensing this aura, Lei Qianjiao's beautiful eyes widened, and she couldn't help but exclaim:
"Golden Immortal?! He actually broke through to Golden Immortal?!"
Thunder God was not surprised by this at all, and said calmly:
"It seems he has finished absorbing, so the accumulated energy has erupted all at once."
"Just watch, little girl, this is only the beginning."
"His power should continue to surge."
Thunder God's words were not wrong.
For as soon as his voice fell, Wu Tian's aura immediately began to climb rapidly, like a rocket.
And under Lei Qianjiao's astonished gaze, Wu Tian's realm also surged.
First-turn Golden Immortal, second-turn Golden Immortal, third-turn Golden Immortal, fourth-turn Golden Immortal...
