Is that a Wisp?

"How come none of the Yellow Demons have returned?" Grotak frowned as he asked, looking at a Red Demon that had returned.

"I'm not sure why. There was nothing there that could even pose a danger to even a Green Demon, not to mention them," the Red Demon expressed its confusion.

"Bring in a team of demons with you. Redirect part of the demons marching towards the cities to come here," Grotak commanded, watching the Red Demon follow it soon after.

Watching the Red Demon leave, Grotak muttered, "Had the instinct in the Demons not existed, this would have been many times easier. I could simply command them to do things. But now, I have to constantly remind them to come here. Otherwise, they instinctively forget the mission and start marching towards the cities once again."

"That's why this place sucks." Grotak shook its head as it let out a sigh. "Us demons don't have a freedom of will, self-preservation, and concern for fellow brethren."

It then muttered, "Maybe once we leave this place, that might change."

Soon, the Red Demon returned with a group of demons, entering a path before marching forth.

The Red Demon turned around, pointing at a chamber before them, saying to the other demons it had brought with it, "The moment we enter there, around 30 Monster Geckos would appear to kill us. Their strength is inferior to even a Violet Demon, so you don't have to worry. However, they'll try to swarm you. Their blood can numb you or even freeze you if the quantity is sufficient."

"Once they are killed, I'll devour their corpses and produce some miasma. Store it in your bodies so you can heal when you receive damage. Also, beware of the walls. They can absorb the miasma. On top of it all, they also give me a bad feeling." Once the Red Demon finished saying its piece, it began to walk towards the chamber.

The moment the group entered it, numerous Monster Geckos rushed out like usual, surrounding them. Immediately, a battle erupted as the demons annihilated all the enemies within a minute.

The Red Demon hurriedly began to devour the Monster Geckos, commanding the Yellow Demons to do the same. Once they began to produce the miasma, it shouted, "Hurry and absorb them."

Even though it had shouted, some of the miasma was still absorbed into the walls as all the demons were startled. After devouring all the Monster Geckos, the Red Demon muttered, watching the Monster Gecko blood on the floor be absorbed into it, "The deeper we head into, the stronger the walls suck in the miasma. Our blood will also get sucked if it spills."

Once they cleared up the area, they began to walk further, soon approaching a place where the floor, the walls, and the ceiling were riddled with holes. The Red Demon said in a hurry, "This trap spans a hundred meters. Cross it at your maximum speed."

Saying its piece, its figure shot forth, reaching the other side within a second. The Yellow Demons followed suit, doing the same. When the Green Demons tried to cross it, bone spikes exited the holes, intending to pierce them. Fortunately, the Green Demons swiftly evaded them all, reaching the other end.

There weren't any Blue or Violet Demons in the group. So, all the Demons had managed to evade the trap, having reached the other side. And right as they had done so, the floor underneath them caved in while the ceiling caved in on them.

The Red and Yellow Demons were fast enough to unfurl their wings and evade within that duration. But since they arrived with the objective of exploration, they hadn't done that. The Red Demon slowly descended through the tunnel as it thought to itself, 'This trap didn't activate before. Is it based on the number of demons exploring?'

It then arrived at the bottom, noticing large bone spikes protruding from the ground, ready to impale any unfortunate soul that had fallen. Some of the Green Demons were unable to stop themselves completely since they fell atop each other.

Some of them crashed into the bone spikes, breaking them while getting injured a bit. Thankfully, by consuming some of the miasma stored in their bodies, they swiftly healed the injuries. The Red Demon broke some of the bone spikes at the end, landing on the ground as it pointed at the path treading forward. "Let's get a move on now."

They threw all the broken bone spikes into the bone spikes protruding from the ground, beginning to march into the tunnel. For the next hundred meters, nothing happened. But out of nowhere, numerous walls began to come up behind them, catching all the demons unaware.

In any case, the walls had just fallen. So, by the time the demons reacted, the path behind them was already closed up. Moreover, at least 10 such walls had fallen one behind another. So, even for the Red Demon, it would take some time to punch through them all.

Right at this moment, a space opened up at the top as around fifty Mutant Monster Geckos dropped in, attacking the demons readily.

'They're somewhat stronger now,' the Red Demon thought as it punched and retracted its fist immediately, dodging the blood splash, shouting, "Avoid its blood! Don't let it splash on your body!"

"Guh!" Suddenly, while they were fighting, one of the Green Demons shouted as it crouched on the ground, trembling in pain. It was one of the Green Demons that had been mildly injured by the bone spikes before.

And right as it began to shout, the other Green Demons that had been injured also began to shout. Suddenly, they opened their mouths while screaming in pain as a vine sprouted out, soon growing in thickness before turning into a tree, killing the Green Demons in the process.

Moreover, thanks to absorbing the rich vitality and dense nutrients in the bodies of the Green Demons, the bone trees rapidly began to form the fruits that grew to the maximum within a minute, causing them to ripen before falling on the ground.

From each walked out a Mutant Monster Gecko, causing the Red Demon to frown.
