"Where the fuck did we go to... The signal of my phone isn't working and I can't sense the outside world with my perception."
Sofia heard Fein's voice near her as they appeared in a strange place. She could feel the damped ground in their foot. The ground has small cracks like that of spider webs all over the place. In the gaps of the cracks, yellow mist ooze out from it that gave her skin a warm sensation. The yellow mist gave a kind of musty smell that she couldn't describe.
When she raised her head, her eyes couldn't help but widen. The speed of her heartbeat increased. Because bones are scattered around the vicinity. She couldn't quite make it out if it was bones from humans or monsters or both.
The ceiling was at least a hundred meters from them, and it was made of stone as dark as ink. There are thousands of orbs etched on the ceiling that gave the place light.
'They are just like a moonlight,' Sofia thought inwardly. She knew that without the orbs, the place would be nothing but darkness.
In this strange place, Sofia felt an indescribable beauty, solemnity, and hidden danger.
"What a strange place," Fein muttered. He took the sword from the sheath, ready for anything that would come their way.
In such an unknown place, even if he has the offensive power equivalent to SS rank. He doesn't plan to be careless because of overconfidence. After so many lessons in the past, Fein was already ingrained in his bone that he must exercise constant vigilance and awe of his enemies and dangerous places.
Now, they are not in their territory and are completely unfamiliar with the place. He didn't know what being was out here with them at the moment.
"Let's go." Fein started to walk.
With every step, he could hear the slight noise of the splash of water. As the group proceeded, they covered forty meters of their original place without encountering anything.
The only difference was, the orbs on the ceiling exudes yellow light and the cracks in the ground became bigger. Yellow mist also became thicker and it was already visible to the air, even if they didn't look at it intently.
"What a damned smell." Fein rummaged through his storage space and took out face masks for the four of them.
The other two face masks had different shapes, specifically customized for Voli and Aoi. Fein has already learned his lesson from his last mistake.
Aoi and Voli quickly wore the mask on their face. As a beast, their olfactory sense was like a curse in such an environment. The yellow mist was really unbearable for them and they have to lessen their number of breaths. Fortunately, as an S rank, they could hold their breath for hours.
Just like that, they covered another one hundred meters' distance after walking for twenty minutes. The passage of this time became a bit narrow that Voli have to shrink himself to the size of a human. The orbs on the ceiling changed to the color red, and hundred of holes replaced the original cracks.
Fein threw a random object into one of the holes and he couldn't even hear the sound of the impact. Due to this, he knew that the depth of the holes wasn't something he could imagine or it might even be bottomless.
Seeing this, Sofia and Voli were surprised. "It would be bad if one of us fall there, right?"
"Definitely, but don't worry. It's not as if we can't fly." Fein continued to walk while deliberately avoiding the holes. "Though, we should still exercise utmost caution since we don't really know the full details about these holes."
"The only good thing here is that the yellow mist was finally gone." Sofia removed the facemask from her face. She's not really used to wearing a facemask.
Sofia threaded carefully behind Fein. She was afraid that she would slip straight into the hole. The red light from the orbs gave her an uncomfortable feeling.
Aoi and Voli glanced at the holes with a wary expressions. In their heads, they couldn't help but imagine that something would suddenly pop out and scare them.
A few hours passed, and Fein and Sofia decided to rest first. They finally got out of the narrow passageway.
In the ceiling, they saw the familiar white orbs, little cracks in the ground, and the yellow mist it continued to release.
"Damn it, those yellow mist again." Fein couldn't help but complain.
Seeing this, Sofia sighed and put her white facemask again on her face.
"Fuck this!" Fein trotted on the way and increased his pace.
Sofia and the other did the same. They didn't want to deal with the yellow mist again, which has a disgusting smell.
"Huh? Same cracks? Same thick yellow mist?"
Sofia sighed as she saw the familiar cracks there were bigger and the yellow orbs on the ceiling. She couldn't help but wonder why the surroundings were the same. Then she noticed a violet flower on the wall. A minute later, they saw a similar passage from before.
"The architect of this place might be smoking weeds when he built this base."
Fein looked at the holes in the ground. This time, he took out a gold coin and brought it in the middle of his finger. With a powerful flick, the gold coin flew toward the hole at a speed faster than the bullet. Fein waited, but there was still no sound.
"It's really bottomless. He guessed this because there was no reaction at all. That flick is enough to kill A-rank. Because he actually infused degu energy and out 60% force with the flick that he had just made.
If the gold coin really hit the ground, the bottom floor of the hole would produce sound. But Fein didn't even hear the slightest sound.
"We're done here. Let's proceed."
Fein looked at his four companions and continued to act as the pathfinder of the group. A few minutes later, they saw the familiar scene again. White orbs in the ceiling.
