Roar!
The demon roared out incredibly loud as the death aura assaulted his body. Because the demon relied on its body for defense and did not have a protective coating of Qi surrounding it, the aura slammed against its body directly.
The flesh of the demon instantly began to wither and rot, becoming a decayed mess of flesh, before it's regeneration kicked in, healing the rotting wounds. The two opposite powers instantly began to fight against each other in a seemingly endless battle.
Bang!
A calamitous lightning strike struck against the demon, piercing through a spot of flesh that had just been withered and weakened. The lightning pierced into the demon's body and began to rampage from within.
Roar!
The demon roared out in anger and pain, but was unable to do anything to stop the rampaging lightning. Its regenerative powers were doing everything it could to stop the aura of death from destroying its body, and so none was left to combat Thunderzen's attacks.
The demon suddenly switched targets, and swatted its massive hand towards Lilian who hovered above its head. Thunderzen knew the demon would attempt this, and instantly appeared before Lilian.
His staff slammed down with absolute power as he sent out a powerful battle art.
Boom!
The battle art collided against the demon, overwhelming it and knocking it deep into the earth. A crater nearly a mile deep formed from the attack, as the battle art and demon's body rent the land asunder.
The aura of death parted around Thunderzen, as Lilian made sure to avoid Thunderzen at all costs. Thunderzen turned around to look at Lilian, whose breathing was starting to become haggard, and her energy wavering.
"How much longer can you last?" Thunderzen asked with concern in his voice.
"Long enough," Lilian replied through gritted teeth, as if using this power of hers took all her focus and might. "Just use your Heaven Suppressing Staff and Thunderfall Judgement already."
Thunderzen stared at Lilian for a moment before his gaze shifted over the lands below. The Bloodfiend sect was completely destroyed, and all the Elder's seemed to have finished their battles.
He had held back out of concern for the safety of his sect members, but it seemed as though they had all fled to a safe distance. Another reason Thunderzen had not unleashed this attack was that it was incredibly draining on his Qi, and so he could only unleash it once. If he used it and didn't kill the demon, the demon would be able to freely roam and destroy everything in its path while Thunderzen recuperated.
With Lilian's help, the best opportunity to kill the demon was now.
Thunderzen nodded his head, and put his one staff away while he took out another.
Even dozens of miles away, John could feel the incredible might of the new weapon Thunderzen had taken out, as it was the most powerful weapon he had ever seen. Not only that, but he could feel a dense soul aura radiate from the weapon, as if it had its own soul.
'An artifact spirit!'
The eyes of the Elder's widened as they saw Thunderzen take out his weapon.
"It's time to leave," the Elder's instructed as they wrapped John with their energy and began to flee at incredible speeds.
Lillian's death aura continued to assault the demon below, which was flying back up to them at incredible speeds from the bottom of the crater. Thunderzen readied his staff in front of him as he watched the demon approach.
An incredibly large and powerful staff image, made of pure lightning Qi, began to form above his head, as Thunderzen prepared to unleash his ultimate battle art, Thunderfall Judgement. It was his strongest weapon battle art, that combined his powerful staff with his incredible lightning prowess.
Just as the demon was about to reach him, Thunderzen slammed his staff down. He felt the artifact spirit draw out most of his Qi to use on this one attack.
"Thunderfall Judgement!"
The staff image made of pure lightning Qi slammed down towards the demon below with absolute power. The demon, who was still being assaulted by Lilian's death aura, slammed out its fist to meet the attack.
…
"Why are we running?" John cried out to the Elder's as they continued to speed off into the distance. He wanted to stay and watch the battle between Thunderzen, his master, and the demon.
Before the Elder's could respond, bright light, followed by a deafening sound boomed out behind John. He quickly turned his head around to look behind him, and his eyes nearly popped out of their sockets.
A massive explosion, over ten miles across, rocked the land where the battle had been taking place. The explosion continued to radiate outwards, upheaving the land and destroying anything in its path.
The Elders carrying John away finally stopped as they had gotten far enough away, and turned around to look at the results of Thunderzen's battle art. Debris rained down all around them, having been thrown dozens of miles away by the explosion.
After radiating outwards for over a dozen miles, the explosion eventually faded, revealing the aftermath for all to see. John's eyes nearly popped out his skull once again as a crater, over a dozen miles across and several miles deep, was carved into the land. Entire mountain ranges had been swallowed up by the attack, which had completely altered the landscape of the once glorious Bloodfiend Sect.
…
High up in the sky above the center of the explosion, a battered and bruised Thunderzen and Lilian floated. Thunderzen had used his power to shield his daughter from the attack, as even Lilian was not strong enough to survive that explosion.
Their eyes surveyed the destroyed land below, looking for any remnants of the demon they had been fighting. However, there were no signs of the demon anymore. Thunderzen breathed out a sigh of relief as he saw this.
"The demon's incarnation seems to have been destroyed."
Unless the summoning was of the highest quality, the creature being summoned was usually an incarnation of its true body, instead of its true body. When the incarnation was damaged enough, it would dissipate, as it had in this case.
Thunderzen's narrowed eyes glanced towards his daughter, who swayed slightly from fatigue. Using that ability of hers drained her considerably, as she had to push it to the very limits to have an impact on something as strong as the demon.
However, the cost had been worth it, as the demon's defenses were weakened by it, allowing for Thunderzen to land the final blow.
"You've done well today," Thunderzen said to Lilian. "Let us return."
Lilian nodded her head and began to fly off in a certain direction. Thunderzen glanced at the now decimated Bloodfiend Sect, and sighed slightly.
The peace he had enjoyed for so long was clearly coming to an end.
