Under the might of the heavenly lightning, the several arrays Zhang Ling had set up around the cave were instantly destroyed, and the adjacent cave collapsed.
The Xuan Turtle had already revealed its true form, transforming into a giant turtle over a hundred feet tall, now hissing towards the sky. Its massive body trembled, covered in a layer of dark blue icy mist.
The water beneath it was also utilized, turning into layers of thick, solid ice. From a distance, it resembled a giant ice turtle.
Hidden within the ice and mist, the Xuan Turtle stubbornly withstood the waves of lightning.
However, the lightning from the sky was no ordinary lightning, but heavenly lightning formed from spiritual power. The power of thunder and fire was rampant, instantly shattering the ice.
The heavenly lightning struck its body, transforming into tiny sparks of lightning, intertwined into a layer of azure lightning net, covering the entire body of the Xuan Turtle.
As the lightning flashed, wisps of blue smoke rose from the Xuan Turtle's body, which became somewhat charred. Its head, after being struck by several heavenly bolts, became a bloody mess.
The Xuan Turtle roared towards the sky, a layer of blue light shield appearing around its body, resisting the continuous lightning strikes.
At the same time, the wounds on its body healed rapidly at an astonishing rate. This was the power of physical regeneration; without this ability, it would have already been severely injured under the onslaught of heavenly lightning.
For a time, the sound of thunder reverberated around, and the giant roars shook the earth, causing the entire canyon to tremble. This kind of heavenly might inspired awe. Zhang Ling could do nothing but watch.
The demon beast's transformation tribulation was aimed at the demon beast itself; even if he wanted to assist, he couldn't. It could only rely on the Xuan Turtle's own resistance.
After an unknown amount of time, after countless lightning baptisms, the surroundings fell into a brief period of calm.
The ground was already full of scars, with huge crisscrossing cracks everywhere. The mountain walls on both sides had been shaved off, shortened by a third.
Deep in the canyon, the pool where the Xuan Turtle was located had long disappeared, replaced by a hundred-acre-sized pit. A mass of dark blue mist swirled within, like a giant vortex, vaguely revealing a hundred-foot-tall giant turtle hidden inside.
The thunderclouds in the sky also strangely formed concentric waves of lightning, like a dancing thunder dragon, but the heavenly lightning did not fall for a long time.
Zhang Ling was no longer in his original position, having retreated a great distance further, watching this scene with a solemn expression.
A quarter of an hour had passed since the first heavenly lightning strike. Although the time was not long, the Xuan Turtle had already endured countless lightning bolts.
Now that the heavenly lightning had not fallen for a long time, it was accumulating power, and the pressure of the heavenly lightning would become stronger with each wave.
Although there were records of transformation tribulations in some ancient books, they were only brief mentions. He didn't know much about it, nor did he know how long the tribulation would last.
He could clearly feel that the Xuan Turtle's aura was unstable, and it was obvious that both the second soul and the Xuan Turtle had suffered considerable injuries.
If this continued, with the power of the heavenly lightning constantly increasing, even if the Xuan Turtle possessed a regenerative body, it wouldn't be able to hold on for long.
Before long, another wave of heavenly lightning finally fell.
In the blink of an eye, the mist vortex in the deep pit was scattered, revealing the Xuan Turtle's body. A layer of dark blue spiritual light emerged, protecting its entire body.
Countless lightning strikes came, causing the Xuan Turtle's body to tremble, but the protective spiritual light did not break, stubbornly resisting these attacks.
However, the power of the heavenly lightning was naturally more than this. The sound of thunder roared, and the Xuan Turtle's body fluctuated, revealing bright lightning, quickly intertwining together, turning into huge lightning balls, and impacting like a storm.
The Xuan Turtle let out a long cry, opened its mouth wide, and spewed out a large mass of ice mist, forming another thick layer of ice outside its body. At the same time, it retracted its head, transforming into a giant ice ball, rapidly rotating, flying off the ground, and scurrying back and forth in the air.
It seemed to want to avoid the heavenly lightning.
But the dense lightning balls seemed to have eyes, constantly chasing after it and attacking. In a burst of crackling sounds, the ice layer on its body constantly broke and quickly regenerated, and for a time, they were at a stalemate.
If this continued, the Xuan Turtle could resist with its defense.
But at this moment, countless lightning bolts in the sky, like flowing water, converged into a huge lightning bolt a hundred feet wide, accurately hitting the Xuan Turtle. With a loud bang, the Xuan Turtle was directly pressed to the ground, smashing out a large pit.
Then, swaths of huge lightning bolts fell, and the Xuan Turtle was instantly submerged.
Seeing this scene from afar, Zhang Ling was also shocked, his back already covered in cold sweat, with a creepy feeling. Being hit by so many huge lightning bolts at the same time, the Xuan Turtle would definitely not feel good.
But after a glance, he breathed a slight sigh of relief.
The Xuan Turtle spat out its demon core, on which emerged a miniature turtle, which was its second soul. The demon core rotated rapidly, supporting a layer of condensed black light outside its body, which blocked many heavenly lightning bolts.
However, the spiritual light was rapidly dimming, and it wouldn't last long. Spitting out the demon core proved that the Xuan Turtle was also approaching its limit.
And the huge lightning bolts in the sky continued to fall, without the slightest sign of fading.
Zhang Ling licked his dry lips and sighed in his heart. It seemed that the Xuan Turtle might not be able to survive this transformation tribulation. He couldn't help but feel a little disappointed.
Just as he was feeling heavy-hearted, a long whistle flew over from afar.
Zhang Ling glanced in the direction of the sound, and his face changed slightly. He quickly flipped his hand and took out the Illusion Mud, about to activate this treasure, covering his whole body to hide his aura. Immediately, a divine sense swept over him.
Obviously, someone had discovered him, but the divine sense only swept over him and then ignored him, seemingly not caring about his existence.
Through the divine sense reaction, Zhang Ling immediately judged that the person who came must be an old monster at the Nascent Soul level. He had not thought that the Xuan Turtle would attract a transformation tribulation, so he had not made preparations in this regard.
However, he also knew in his heart that the transformation tribulation could not be hidden even if he set up a hidden array. It was expected that other cultivators would be attracted now.
Zhang Ling thought for a moment, then put away the Illusion Mud. Since he had been discovered by a Nascent Soul cultivator, it would be redundant for him to hide. It was better not to act rashly.
However, he secretly pinched a black spiritual talisman in his left hand, which was the Thousand Mile Escape Talisman. Once there was danger, he would immediately activate this talisman. Coupled with the Blood Burning Escape technique that he had recently successfully cultivated, he had some confidence that he could directly escape from this place.
Calculating the time, it had been more than five years since he came to this canyon. In addition to cultivating several secret techniques, his cultivation had also increased slightly.
Zhang Ling suppressed the unease in his heart and stayed calmly in place.
