I walked through the long dark corridor yet again. But, this time it was in the real world. I sighed as I looked back at the long path I had traveled. Currently, I was standing in the place several kilometers underground.

According to Lucio, the reincarnator she knew was located here, in this dungeon. The dungeon was said to be the safest path connected to the outside world. The oldest record in Roslet had mentioned that the prisoners a.k.a the ancestors of Roslet residents were brought to that desolate land by travelling through this dungeon.

I kept advancing. From times to times, I accidentally triggered some classic traps like a pitfalls, spikes, or arrows. The trap itself didn't pose any threat to me but the poisons and pathogen bacteria on the arrow tips and spikes is too troublesome.

"Goodness, I wonder how large is this dungeon?"

I muttered. I checked the locate system of my zodiac brave. I told Karina to stay in position so I could use her to pinpoint my location. I trusted this option than the mini map option as it only showed small part of the area and would only be useless against my sense of direction.

I looked upward. My current position was 100km under the city of Roslet. According to the record, this dungeon would reach the otherside of the mountain beyond the desert and yet so far the furthest boundaey of each floor i had travelled was no more than the outer wall of Roslet.

"Maybe I should descend one or two more levels. Any further than this will not allow me to return before sunset."

I muttered. Travelling alone indeed made me looked like a mentally disordered person as I often to talk to myself. Technically I wasn't alone but Garm doesn't want to chat a pointless talk aside from battle oriented one.

"Maybe I'll bring the whole party to explore next time."

I added. But, there was another strange point in this dungeon so far. Even I had descended more than 10 floors I had yet to meet any single living beings aside from the bacteria on the tip of the spikes.

I stopped for when I found the first large door in this dungeon. There was a mural of a bunch of monsters were rushing toward a single man holding a sword.

"It seems like this is either a monster house trap or a boss room."

I said.

"Finally it's my debut time!!"

Garm said from his sheath hanging on my waist. I gasped as the sword of mine suddenly shouted after staying silent the whole time.

"What? Aren't we going to go inside?"

Garm asked. Honestly I had some urge to do something to this sword but looking back at the situation, I guess I'll let it slide. I just hope that the monster inside was something nasty for cutting so that this guy can suffer even just a bit.

I unsheathed him from his scabbard. The dark blade gave a strong demonic aura. The black luster on the sharp edge gave a hint even to the most idiotic swordsman that this is no ordinary sword. 

I took a deep breath and opened the door. I was made to frown when an absurd scene was shown before me. Red carpet was spread across the room. White wall was furnished by red curtain with golden colored linings. The bright light was emitted by large golden lighting on the ceilings, furnished by diamonds. At both left and right ends of the room, there were two long tables filled with plates of dishes and beverages while at the end of the room across the door there was a large throne.

Simply put, it was that, a ballroom inside the castle. Finding this room in a dungeon was already weird. And the thing that made things even more bizarre was the residents of this room. Sitting on the throne was an undead wearing a bluish crown with shining red jewel and black robe. Then, standing across the room in dress and tuxedos were skeletons and zombies with putrid smell and there were even some ghouls and wraiths mixed in. Each of them were holding a glass or a plate of food while moving as if they were chatting. In other word, this was a party of undead.

The lord of the room stood up from his throne as if he was surprised from my entrance. In that instant, the other undead stopped their chatting act and looked toward my direction.

"...."

"...."

Neither Garm nor I could say anything at that time. I glanced at Garm in my hand and then looked at the undead hordes before me. Feeling awkward, I quickly hid him behind my back.

"Uh... I think I have opened a wrong door. Pardon my intrusion!!"

I bowed in apology. I quickly turned around in my attempt to leave but I don't know when they had stood there but before i realized it, there were four dullahan stood outside and there was even a large Headless Giant Zombie behind them equipped with a mace and 2 meters long butcher knife.

"I think... we need to fight against these guys."

Garm finally spoke.

"Yeah, I think so."

I agreed. At that moment, the undead lord shouted some cries while pointing at me. The horde of undead as well as the elite undead waiting for me outside the room rushed toward me which then started the long battles.
