Is that a Wisp?

"Haah!" The Black Demon shouted, condensing a layer of fire around its body as it jumped up, intending to run away from Krune.

Instead, it gazed in shock as Krune kept pace with it, flying in the air as he condensed a gigantic ice hammer, swinging it towards the ground. The Black Demon then landed on the ground, creating a massive crater due to the impact.

Krune then aligned himself in the air using the air currents generated by the Cloud Whale's ability while being inside it. He then condensed the Cloud Whale to be one meter long, throwing it towards the Black Demon with all his might.

The Cloud Whale further accelerated by generating air currents, using its horn to pierce through the Black Demon's stomach right when it was about to get up.

"Argh!" The Black Demon screamed, pulling out the Cloud Whale as its stomach felt numb from all the Frozen Blood that was injected into it. But right at this moment, the Cloud Whale exploded, blasting a wave of cold energy onto it, causing a layer of ice to form on its body.

The moment the Cloud Whale burst, Krune condensed the active ability within him, accelerating towards the Black Demon while using the generated air currents. He took advantage of the moment when the Black Demon struggled to melt the layer of ice on its body and the Frozen Blood in its stomach that was numbing it.

The Black Demon was quick in its actions, burning itself up to thaw the ice. At the moment it freed itself, it looked in shock when it was unable to feel any miasma around itself. All it saw was ice, caging it in a dome.

Krune arrived behind it, punching its back, sending it flying a couple of meters. However, when the Black Demon landed on the ground, it was shocked to see that it was standing on ice. When Krune sent it flying in the air, he covered the ground with ice as well.

In any case, it seemed he had consumed a tremendous amount of energy to create this ice dome where the walls were more than 10 meters thick. Now, even the Black Demon would need a couple of seconds to break free from the ice dome.

Sadly, two seconds were a luxury it didn't have. After all, Krune continued to attack it nonstop, overwhelming it in close combat. Even though the Black Demon had lived for more than 2000 years, it hadn't fought much over this time.

All it had ever focused on was a method to obtain Spiritual Energy to break through its natural limits. But in contrast, Krune fought nonstop in the around 240 years he had been alive. The battles on Layer 3 only further improved his close combat abilities.

So, without any question, Krune overwhelmed it brutally. Without any miasma to heal itself, it was getting pummelled nonstop.

The Black Demon tried to pull in all the miasma it could but was unable to use it. The miasma landed on the ice dome, unable to enter. Even though it was melting through the ice, it would take some time before it could do so.

Moreover, Krune also continued to heal the damage to the ice dome while pummelling the Black Demon. Grabbing the palm-sized Cloud Whale, Krune plunged it into the Black Demon's neck, injecting some Frozen Blood into it, causing the Black Demon to flinch.

He then attacked its left shoulder, doing the same. Left shoulder, right shoulder, left wrist, right wrist, right thigh, right heel, left knee. And eventually, the forehead when the Black Demon was a step slower in reacting to his attack.

He injected Frozen Blood into its forehead, pulling it out as he evaded an attack, swerving to its back as he plunged the Cloud Whale into the back of its neck. Every time he plunged it, the Cloud Whale injected all the Frozen Blood into the Black Demon's body, unleashing it like an air needle.

Thus, the Frozen Blood penetrated deep into its body. Compared to the start when it was able to vaporize the Frozen Blood in its body using the miasma, the Black Demon was now slower than before as it was no longer able to do so.

Having never been attacked for around 2000 years, it hadn't prepared itself as the Red Demon Krune had fought before. Slowly, it was losing its ground, finally shouting in alarm, "Why are you killing me? All my life, I never attacked a city."

"Your existence is a danger to my wife," Krune muttered, plunging the Cloud Whale through its mouth, causing it to explode and freeze its internals. He quickly pierced the Black Demon numerous times, causing its internals to freeze up.

After that, he expanded the Cloud Whale's length a bit, piercing the Black Demon's neck many times, riddling it with enough holes that he was able to tear its head from its body. Upon killing the Black Demon, Krune grunted in exhaustion, slumping to the ground as he muttered, "That was a strong foe. Thankfully, I didn't try to fight it while I was at Tier 5. Even at the peak of Tier 6, I still faced so much difficulty."

Krune patted his stomach, realizing that he had expended all the ice spheres he had prepared. And now, there was just four crimson rings worth of energy in his Ocean Heart. Had he delayed any longer, then Krune would have expended all his energy and would have been the one to die.

"That was risky." He then condensed the Cloud Whale around himself, holding the Black Demon's corpse. He dared not expose it to the miasma in fear that it would revive instantly. With that, he used the Cloud Whale to act as a barrier against the miasma that tried to gush into it.

Black Demons were automatically able to attract the miasma, even if it was just a part of their body. He had understood that while in the city when he tried to use the horn.

The Cloud Whale soon arrived at the flight of stairs as Krune deactivated it and activated it, bringing Hazak and the travel items within it. Now summoned at its maximum length, the Cloud Whale took off to the skies as Krune gave the Black Demon corpse to Hazak. "It was even able to cultivate.. Ensure that you are able to absorb that trait."
