As the lightning from the Thunderclap Sword, transformed into a streak of lightning, flew towards him, Wu Tian's expression did not change much.
He suddenly strode forward, caught the lightning in his hand, flipped in the air, and then gripping the hilt with both hands, thrust it heavily towards Su Qiannai!
Purple spiritual energy formed a barrier above Su Qiannai's head.
Upon impact, the barrier immediately caved in.
For a moment, purple light and lightning intertwined, and the qi surged like a raging storm.
Such a confrontation had reached an extremely high level.
Let alone martial artists, even spiritual cultivators below level six would surely perish if caught in it!
Wu Tian gritted his teeth, his face contorted in ferocity.
Spiritual energy surged madly within his body, pouring into the Thunderclap Sword wave after wave.
Yet, even so, he was still unable to break through Su Qiannai's defense!
In contrast, Su Qiannai appeared remarkably calm.
She felt almost no pressure, and said with a light laugh, "If this is all you've got, it's probably not enough."
With that, the purple spiritual energy violently erupted outwards.
Wu Tian's expression changed, and he lost his balance, being sent flying back!
Thud, thud, thud…
Wu Tian's footsteps retreated a dozen paces on the ground before he managed to stabilize himself.
He looked up at Su Qiannai, only to hear her chuckle, "Young Master, although you have already reached the strength of an eighth-level spiritual cultivator."
"But to be honest, if this is your performance, then you are truly disappointing me."
This light laugh pierced Wu Tian's heart like a blade.
He grunted, and then charged towards Su Qiannai again!
He flipped up, and at this moment, lightning bloomed all over his body like a flower!
Immediately after, he transformed into five lightning shadows, pouncing down like a net!
Seeing these lightning shadows filling the sky, a hint of disdain flickered in Su Qiannai's beautiful eyes.
Then, her figure suddenly vanished, flashing past each lightning shadow!
The moment she returned to her original position, all the lightning shadows in the air froze for a moment, and then exploded!
"This kind of move is still not enough for me," Su Qiannai said with a smile, watching the brilliant and fierce lightning gradually dissipate in the air.
But she soon froze, because she realized a serious mistake.
Wu Tian... had disappeared!
"Where are you looking?"
A cold and low voice sounded from behind.
Su Qiannai instinctively turned her head, only to see Wu Tian raising the Thunderclap Sword high, about to cleave down at her!
"Heavenly Thunder Break!"
A roar, as if carrying the might of collapsing mountains and cracking earth, followed by fierce lightning instantly engulfing Su Qiannai!
This move, Heavenly Thunder Break, was the same one Wu Tian had used to break open the stone door earlier.
At that time, he was only a seventh-level spiritual cultivator, and now, with his spiritual power level, its power could only be stronger, not weaker!
Boom!
Another deafening sound, and the entire altar violently shook.
The floor tiles were blasted seven or eight meters high, and the thick dust rose like a dense fog.
A slender figure shot out from the dust and then landed steadily on the ground.
Soon, the dust dispersed, revealing Wu Tian's figure.
He held the Thunderclap Sword, his chest heaving violently, and his face was slightly pale.
But at this moment, Su Qiannai's familiar light laughter sounded again from ahead, "Not bad, this is more like it."
"This is interesting."
Wu Tian was startled and looked forward in shock.
He saw Su Qiannai standing gracefully, completely unharmed!
"How can this be..." Wu Tian couldn't believe such a thing.
He had not held back at all, and this Heavenly Thunder Break was the limit of what he could do.
An attack like this, even if it landed on an eighth-level spiritual cultivator, would surely kill them!
But why was Su Qiannai completely unharmed?
Could it be that the gap between an eighth-level spiritual cultivator and a ninth-level spiritual cultivator was truly this vast?
Thinking of this, Wu Tian felt unwilling no matter what.
His spiritual energy had been increasing at a sufficiently fast rate.
Even in history, he could probably rank among the best.
Yet, even in such a situation, he still couldn't change anything!
What was the point of such improvement then?
The more Wu Tian thought about it, the more unwilling he became.
He couldn't accept it, so even if he was outmatched, he would not give up easily!
He gritted his teeth and once again charged towards Su Qiannai with his sword.
Lightning flowed along the blade, as if it could cleave through gods and demons.
He swung his long sword with all his might, and with each swing, a streak of lightning flew out, pressing towards Su Qiannai.
Su Qiannai stood still, purple spiritual energy swirling around her, as if possessing sentience, blocking all of Wu Tian's attacks.
Wu Tian continued to slash, feeling as if his neural pathways were burning.
As the battle continued, the sound of fierce impacts was endless.
Every exchange between the two erupted with unimaginable energy, spiritual energy flying everywhere, causing wave after wave of explosions on the altar.
Wu Tian had almost exhausted himself, but no matter how much effort he put in, he still couldn't break through Su Qiannai's defense!
Seeing his almost berserk state, Su Qiannai shook her head and said, "Young Master, you should calm down a bit."
With that, the spiritual energy swirling around her immediately exploded.
And that powerful shockwave once again sent Wu Tian flying back.
This time, Wu Tian's condition was much worse than before.
Such frequent attacks were constantly increasing his consumption.
At this moment, he felt his body becoming weak.
When he landed just now, he almost couldn't stand steady.
His mind was in chaos; facing such an opponent, he felt so powerless, as if he could do nothing.
Just as he was wondering how to face her, suddenly, several streams of purple spiritual energy shot towards him, hitting him directly in the chest!
His pupils instantly dilated, and then he flipped several times in the air before finally crashing to the ground.
Su Qiannai smiled and said, "Do you see, Young Master? This is true offense."
"And your attacks, to be honest, are really not enough to see."
Wu Tian struggled to get up from the ground, blood trickling from the corner of his mouth.
His face turned from pale to green, and he suddenly roared up at the sky!
Instantly, purple spiritual energy flew out from his body and rushed towards Su Qiannai!
"Oh? It can be like this?" Seeing this, Su Qiannai couldn't help but raise her delicate eyebrows.
With a casual wave of her hand, that spiritual energy immediately dissipated.
Then, she looked at Wu Tian with interest and said,
"You transferred the damage using the Great Shift of Heaven and Earth?"
"It seems Young Master, you have narrowly escaped death."
