Is that a Wisp?

'It's a shame for the Whale Tooth Sword and Daggers. But, I can't bring them with me, not in my current state at least.' Krune sighed, feeling that it was a waste. Then again, at the end of the day, they were just replaceable weapons. The most important goods were already in his possession.

'And now, I have to patiently wait for the right moment,' Krune thought as the Cloud Whale appeared beside his constrictions, freezing them first before using the air needle on them. Using Moving Ripple, Krune made the ice absorb all the sounds from the air needle drilling into the constrictions.

He made it as slow as possible, breaking through one constriction after another. He used the second Blood Essence Crystal, subsisting the energy to the Cloud Whale to aid in its activities. Soon, he managed to break free of the restrictions without alerting the guards.

His restrictions weren't too strong. It was because he was pretty weak when compared to the humans he had seen till now.. Secondly, his limbs were broken while his bones were crushed into pieces. In short, it wasn't possible for him to flee. That's why Krune was able to break free of the restrictions.

He was unable to move his body, though. So, all he could do was remain sitting, biding time for his escape. As for the lock on the door, it was just a handle. It could be moved using the Cloud Whale at any time.

With that, Krune awaited, observing through his Sonic Radar that the Red Demon was recovering rapidly. The Cloud Whale held two Frozen Cylinders in its body, lying in wait at the entrance to the Red Demon's cell.

After thinking it through, the Cloud Whale appeared before the Red Demon, making its presence known. It then arrived beside one of the constrictions of the Red Demon that prevented it from even applying power in its hands, beginning to drill through it as it turned invisible.

The Red Demon was confused about its identity, but upon seeing that its constrictions were getting removed one after another, it smiled insidiously, focusing on healing itself even further. Soon, it made a complete recovery, noticing the Cloud Whale gently place the restrictions on the ground.

After that, it turned invisible once again and arrived before the guards, destroying the two frozen cylinders within its body as it blasted out an air needle, but now using the Frozen Blood, aiming at the mouth of the soldier the moment he yawned.

"What?" The other guard was startled as his mouth was also filled with Frozen Blood that suffocated him, preventing him from uttering any sounds. While he twitched on the ground, the Red Demon exited the cell, swiftly twisted their heads and placed them within the cell.

It then smirked, its figure flickering as it appeared before two other guards, instantly twisting their necks as it entered the cell they were guarding, approaching the Yellow Demon within, telling it, "Get ready. Eat the humans to recover."

Saying so, it broke off all the restrictions binding the Yellow Demon, emitting miasma that seeped into the Yellow Demon's mouth, stopping after watching the other party heal rapidly. "Wait until my orders to move out."

As the Yellow Demon nodded, it exited the cell, flickering from the place as it killed two more guards, dragging them into the respective cell as it arrived before the second Yellow Demon bound there, freeing and feeding it some miasma as well.

In the same manner, it continued to kill the guards, soon killing everyone on the floor without causing a single commotion. 'Those red crystals…whatever they were, they're incredible. I'm still full of energy. I can release enough miasma to heal every demon locked in this cell.'

It was no longer able to see the Cloud Whale. But it didn't have the time to think about it now, intending to proceed into the upper floor when the Cloud Whale appeared before it once again, making circles in the air.

"Are you telling me to not head up?" As the Red Demon whispered, the Cloud Whale danced in the air, confirming it.

"How strong are they? And how many?" As it asked, the Cloud Whale pointed at the Yellow Demon that had arrived behind it and then made three lines in the air.

"So, there are three humans on the Yellow Demon's level above. What about below?" the Red Demon asked.

The Cloud Whale moved to indicate that there weren't any on the Yellow Demon's level below. Smiling, the Red Demon unleashed a bit of its miasma, summoning the ten Yellow Demons that it had rescued. As for the rest of the demons, they were weaker.

For a stealth operation, they wouldn't be suitable. So, it swiftly rushed with the Yellow Demons, cleaning out all the human guards one floor after another. After emptying the prison floors except the top three, the demons devoured all the slain humans to replenish themselves even further.

They then arrived at the floor just below the top three floors. The Red Demon looked at the group of Yellow Demons behind it, nodding once as they flashed to the upper floors, swiftly overwhelming their opponents with sheer numbers.

Brimming with energy, the Red Demon was too powerful for the three human powerhouses on the floor to face against. At the same pace, they cleared out all the guards in the top two floors as well. Starting from the top floor, the Red Demon healed the captive demons and freed them.

Eventually, it arrived on the third floor from the top, freeing the demons one after another before it noticed that one of the cells was vacant. It was odd because all the cells at the top were always filled with demons. Only the bottom floors had empty cells.

But upon seeing that it was empty, it didn't bother thinking about it further. The Cloud Whale no longer appeared before it. So, it swiftly appeared on the terrace once, glancing around to pick their route before returning into the building.

The Red Demon looked at the differently colored demons, telling them, "I won't tell you the way I was rescued in case you spill the secret to the humans lest you get captured. We are in the heart of the Human City. Escaping would be difficult. We might even get captured once again."

"If it feels like you'll get captured, you know what to do, right?" It then glared at the demons, watching them nod in response. The lot of them congregated on the ground floor, overcrowding the place to the extent some of the demons had to remain on the second floor.

Having eaten the guards, they were brimming with strength now. Following the Red Demon's lead, they broke through the prison entrance, spilling out like a tsunami as the humans that witnessed the scene were frightened.

"They're finally leaving." Krune heaved a sigh in relief as the Cloud Whale opened his cell door. It then manifested around him, bringing him out of the door before placing him on the corridor. It then brought his bag.

Upon seeing that the Red Demon had basically cleared out the prison cell, Krune was glad. But, just at this time, another thought struck him, 'Right, if the bag disappeared, then it would seem obvious that I had escaped. I don't want them to search for me later.'

Krune observed the state of the chairs in the other cells, making the Cloud Whale bigger as it did the same to his chair as well. This way, it would seem like he hadn't escaped, but had been devoured by the demons.

To make that, the Cloud Whale sucked in the blood on the corridor, splattering it on his chair exactly as how it would look if he was devoured there. And to make it seem real, it sucked in his blood and added it to the blood mixture.

The blood indeed froze up, but thanks to the temperature difference, it was thawing slowly. That level of detail was enough to make it apparent that he was indeed killed in the place. Krune didn't forget to do the same to the Red Demon's chair.

Now, there was no way for the investigations to conclude his hand in this. After all, he had displayed his abilities to countless people in the battlefield. So, it was easy to make deductions based on the extent of the damage.

Because of that, he had no choice but to leave his bag behind. As for the Frozen and Exploding Cylinders, he exploded them in the room, making it seem like they had exploded when the demons had fiddled around.

The heat from the exploding cylinders set the room aflame as the fire soon spread towards the other rooms as well.

'The perfect way to destroy all traces of me,' Krune thought as the Cloud Whale placed all his important items in a tiny bag he had stolen from the office room above. It seemed like a common bag, and there were countless such bags there, so it wouldn't be noticeable if one of them went missing.

Besides, there were bigger problems to worry about for the humans.

The Cloud Whale manifested around him as Krune lay within it in a sleeping pose, having closed his eyes. He relied on his Sonic Radar to navigate, using the third Blood Essence Crystal. The same as before, the Cloud Whale turned invisible.

As the prison entrance had been blasted wide open, it flew out stealthily. Krune was able to see the extent of damage the demons had wrecked around. Those imprisoned had been higher up in the food chain.

So, each demon was immensely strong. With that, the average human soldier was unable to face them as the demon horde massacred their way through, razing the place to fire as numerous sky scrappers collapsed to the ground.

It seemed the Red Demon had placed to wreck as much damage as possible to the human city while they were escaping. Moreover, all the demons constantly devoured the humans they had killed, digesting their spoils as they released their signature miasma, filling up the air slowly.

This miasma rejuvenated them, healing them immediately upon any injury. As the miasma spread, they became stronger, able to fight better and devour even more humans. Through that, they released even more miasma, causing a beneficial cycle to them and a vicious cycle to the humans.

As for the perpetrator, he was escaping using the Cloud Whale, unaffected by the death and chaos below, continuing to head far away from the chaos of the place.
