As they walked further inside, visions constantly flickered in their minds, as though hundreds of Demon Beasts were lunging at them from every direction.
However, these low-level illusions had no effect on Nie Li whatsoever, as his mental fortitude was already incredibly resolute.
Beside him, Xiao Ning'er, struggling against the illusions, had turned slightly pale, her clothes nearly soaked through with sweat. Even past geniuses who had entered the Celestial Illusion Sanctuary had never dared to go this deep. The further in one went, the more perilous the sanctuary became.
Nie Li sensed a powerful wave of killing intent surging toward him from the distance.
It was the aura of the Heaven-Fallen Divine Thunder Sword!
This terrifying aura alone was enough to impose immense pressure!
The core of the Celestial Illusion Sanctuary was precisely this Heaven-Fallen Divine Thunder Sword! The entire sanctuary was structured around it!
Just as the onrushing killing intent was about to sweep over Xiao Ning'er, Nie Li suddenly let out a thunderous roar, which crashed into Xiao Ning'er’s Soul Sea like rolling thunder. Her expression tightened, and her mind instantly cleared.
“Are you alright?” Nie Li asked with a faint smile, looking at Xiao Ning'er.
“Mm, thank you, Nie Li!” Xiao Ning'er gave Nie Li a grateful glance. Without his help, she would have been consumed by that terrifying killing intent.
Her thin clothing, dampened by sweat, clung tightly to her delicate skin, accentuating her alluring figure. Her chest stood proudly, further highlighting her captivating charm.
Ning'er is becoming more and more fascinating. Nie Li was momentarily dazed, then awkwardly touched his nose and averted his gaze.
Sensing Nie Li’s intense stare, Xiao Ning'er’s pretty face flushed red, and she lowered her head. Although embarrassed, she felt a subtle hint of joy within.
“Ancestor Ye Yan, if I manage to subdue the Heaven-Fallen Divine Thunder Sword, will you truly submit to me?” Nie Li quickly changed the subject, addressing the ancestor.
“Of course,” Ancestor Ye Yan replied proudly. “I keep my word! If you truly subdue the Heaven-Fallen Divine Thunder Sword, I will have no reason to remain here in the Celestial Illusion Sanctuary, as my soul is bound to the sword and would dissipate otherwise. However, boy, let me give you a piece of advice—drawing the Heaven-Fallen Divine Thunder Sword is no simple task!”
“If it were simple, it would hardly be challenging!” Nie Li said dismissively with a light smile.
Ancestor Ye Yan was puzzled. How could Nie Li be so confident?
If Nie Li truly managed to draw the sword, leaving the Celestial Illusion Sanctuary and seeing the outside world wouldn’t be so bad!
As time passed, they gradually approached the heart of the sanctuary. In the distance, upon an ancient altar, a divine sword came into view. The sword was bathed in a radiance of lightning, and the sound of wind and thunder resonated around it.
A terrifying killing intent!
The divine sword possessed a spirit of its own. Even from a hundred meters away, it emanated a piercing cold that chilled one to the bone.
“That’s the Heaven-Fallen Divine Thunder Sword?” Xiao Ning'er couldn’t help but sigh. Even at such a distance, she could feel an overwhelming soul pressure, making even a single step forward extraordinarily difficult.
Though she sensed the immense pressure on her soul, Xiao Ning'er simultaneously felt her Soul Power rapidly evolving and growing. The Wind Thunder Wing Dragon Art circulated swiftly within her body, and within her Soul Sea, it seemed as though a winged dragon was soaring.
After a moment, her Soul Sea abruptly erupted, surging through every limb and meridian.
Boom, her mind became exceptionally clear.
A breakthrough!
Silver Five-Star!
The Wind Thunder Wing Dragon Art was a cultivation technique of bold advancement, its speed far exceeding that of Nie Li's Heavenly Dao Divine Art. Under the guidance of the Heaven-Fallen Divine Thunder Sword, and with Xiao Ning'er already having reached the level of Soul Power Manifestation, her advancement was astonishingly fast.
She was now only a hair's breadth away from the Gold rank!
Although her cultivation hadn't reached the Gold rank, Xiao Ning'er's technique was too powerful. Even an ordinary Gold One-Star or Two-Star expert might not necessarily be her match.
Watching Xiao Ning'er's cultivation surge forward, Nie Li couldn't help but smile faintly. Ning'er now possessed enough ability to break free from her fate in the past life.
"Merge with this Demon Spirit," Nie Li said, handing a Demon Spirit Stone to Ning'er.
"What is this?" Ning'er looked at the stone in confusion.
"It's a Wind Thunder element Spirit. A Wind Thunder Sky Sparrow, with divine-grade growth potential!" Nie Li said, pressing it into her hands.
"Nie Li, I... I..." Xiao Ning'er looked up, tears glistening in her eyes. Nie Li was so good to her; she didn't know how she could ever repay him.
Nie Li patted Xiao Ning'er's shoulder with a slight smile. "Hurry and merge with it. With your current strength, once you merge the Wind Thunder Sky Sparrow, I'm afraid I won't be your match anymore!"
In order to follow in Nie Li's footsteps, and to one day stand side-by-side with him!
Xiao Ning'er accepted the Wind Thunder Sky Sparrow's Demon Spirit Stone and began the merger.
