Yae, they're coming your way!
Yes!

　Using the crumbling city walls as a shield, that thing disappears from my sight.
　The sound of metal echoing through the walls. When I went around the wall, he was cutting into Yae.
　The jet-black knight armor and the devastating large sword. Its massive body exudes strength. The two legs supporting it caught the earth and did not let go, and not a shred of mercy could be found in the arms wielding the great sword.
　No, there may already be no such emotion as mercy. For that dark knight has no head.
　Dullahan. A demon who died a regrettable death on the decapitation table, the knight wanders around looking for a head that fits him and continues to hunt for human heads. The world he was from and the lore is different, but that's who he's going to defeat this time.
　He confronts Dullahan in a pincer movement with Yae. I send Yae a signal with my eyes, and when she confirms that the magic power of light is gathered in the index and middle fingers I held up, she quickly leaves the scene.

''Light, pierce me, shining holy spear, Shining Javelin.

　A spear that emitted a dazzling light flew straight from the fingertips pointed at Dullahan. The spear pierced the left shoulder without fail, and the black arm flew off in a thousand pieces.
　However, blood did not spatter from the wound like a human being. I'm sure you'll be able to find a way to make the most out of your time in the event that you're in a position to do so.
　At that moment, a shadow jumped in from the side and gouged out the side of the headless knight with its fist. As it was, the shadow exploded with a sharp spinning kick at the opponent who had lost his stance.

''Else!　What about the unicorn?
'It's all taken care of!　Jesus, there were almost 20 of them, for God's sake!

　Linse comes running in from afar. Alright, here's the real deal.
　Dullahan staggered for a moment at Else's unexpected attack, but he immediately calmed down sideways, aiming at the neck of the opponent who attacked him with that great sword. I'm sure you'll be able to find out more about this in the future.

''Flame, come on, fireball of purgatory, fireball!''

　The fireball released by Linze hits Durahan's back. The eight-fold sword flashes shimmer through the gap, but they are blocked by the great sword he swung at.

''Stubborn!　It's going to be bad if it becomes an endurance fight.

　Unlike the other side, one decent bite from that big sword here would probably result in instant death, or at best, the loss of an arm.
　Dullahan is already lifeless and mortal, the so-called undead. The undead are generally extremely vulnerable to light-attribute magic. The light attribute can be used by Linse, but she wasn't that good at it. I have no choice but to do it. .........Let's go with that one.

''Linse!　Use your ice magic to stop that guy. Just a few seconds.
'What?　Wow, I get it!

　Hearing this, Yae and Else start to move. To distract Dullahan and divert his attention away from Linse and I. I know, our teamwork is quite good. I know, our teamwork is pretty good.

"Ice tangle, freeze curse, ice bind.

　Linze's magic was activated and Durahan's feet instantly froze in place. In an attempt to escape from the spell, the ice cracked and began to peel away bit by bit as the headless knight put his strength into both legs. 'Not so fast.

''Multiple!''

　My non-attribute magic activates. Four magicians float in the air around me. Next, I cast a light attribute spell.

'Light, pierce me, shining holy spear, shining javelin.

　Immediately after, four spears of light shot out from the four magic circles with great force. The spears all headed towards Durahan in a straight line. A non-attribute magic that omits continuous chanting and enables simultaneous activation. That's 'Multiple'.
　The headless knight managed to escape from the attacking spear of light, but Linse's ice would not allow it.
　With all the light all over his body, Dullahan lost his right arm, his side, his left leg, and then his chest as he slowly collapsed.
　The pitch-black miasma poured out of his tattered armor and scattered in the wind.
　The headless knight was no longer moving.



''That's taken care of.''
I'm tired, that I am.

　Else lets out a murmur of relief and Yae sits flopped down on the ground. It's not unreasonable. She was the one who kept dodging most of the attacks and was the one who was dealing with Dullahan the whole time.

''It was a miscalculation to have a horde of unicorn wolves with us. It was a close call...''

　Linze seemed to be relieved as well.
　Our guild rank had turned green in the past few months. Black > Purple > Green > Blue > Red > Silver > Gold, changing to third from the bottom of the guild rank. When you reach this level, you'll be recognized as a full-fledged adventurer.
　I was going to accept the green request right away, but Else suggested that I should accept a request from a guild in a different town once in a while.
　So, from Green's request form at the guild headquarters in the royal capital, I chose to defeat the demons that lurked in this ruin.
　Originally, this ruin was the royal capital more than a thousand years ago. It is said that the king of that time chose to abandon this land and build a new royal capital. I guess it was called relocation of the capital.
　I don't know how it was back then, but now there is a castle wall full of holes covered with ivy, cobblestones and buildings that barely retain the shape of a town, and a completely collapsed royal castle, and rubble that looks like it was a complete ruin. Right now, it is truly a ruin.
　It seems that the cycle of monsters and monster beasts living in the ruins has been established, and those who receive requests like us will defeat them, but after a while the monsters will come back to live, and then we will defeat them again.
　It's true that if the demons settle in one after another, they may eventually form a swarm. It's probably best to defeat them regularly.

''But there's nothing to say about the old royal capital...''

　I look around and see crumbling walls, walls, walls. I heard that a royal castle once stood here on a hill with a great view. I wonder if this is where the Duke and Sue's ancestors lived.
　However, I don't know why this city has fallen into disrepair after it was moved. Was it because of the relocation of the capital by setting fire to the castles and houses, as in Tung-tung in "The Chronicles of the Three Kingdoms"?

It would be interesting to see the king's hidden treasure.
No, I don't think so. I don't care if they destroyed the country, but they just moved the capital, that they did.
I know, I know, I'm just saying.

　Else's mouth twitched at Yae's rebuttal. A treasure.
　In my world, there were Tokugawa reserves and Takeda reserves, but I knew these things existed over here as well. I'm not averse to them either. Treasure hunting is a man's romance, after all.
　I suddenly thought of something. I think I have a chance to use that magic.

Search: Treasure.

　I'll use my search magic. If there's something nearby that I can recognize as a treasure, this should tell us. Well, I guess not. I'm not surprised.

You used search?　So, how did it go?
At least there's no treasure in the vicinity.

　I chuckle at Else, who asks excitedly, and answer the search results.

'I see...too bad.'
''But if it's valuable, just because Fuyao-san can't recognize it as a treasure, it might be there, right?

　Oh, it seems that your sister was also in the camp that feels romantic about treasure hunting. As expected of twins.
　It's true that Linze was right, for example, there was a painting by an artist of great value. But if I look at it and think it looks like a doodle to me, then I won't be able to find it by searching for something of value. It's only a surgeon's sensation, a sketchy one, and that's the strength and weakness of this magic. You might react to it after you know the value of the picture.
　You certainly have a point. With "treasures", I had an image of jewels, crowns made of gold, treasured swords, and large small coins skimmed, that kind of thing. Hmmm.....

Search: historical relics.

　If it's "historically valuable," then it's going to catch on. Oh, but this would be useless if I didn't have that knowledge. It's useless if I don't have that knowledge.

I'm stuck.
""What?"

　There it is, something of historical value. The ruin itself is a reaction, but there's more nearby than that. It sharpened my senses. Yeah, I can definitely feel it.

"Which way, that is?
"I think it's this way. I can feel it from this side. It's big, what's this?
"'Big?'

　I continue on as I feel my way through the ruins. Everyone follows me, and eventually we come to the site of the crumbling rubble. Hmm?

From below?　Under this rubble?

　What to do with the debris of a building that seemed to weigh tons. As I was at a loss, Linse stepped forward.

''Flame, blast, Red Lotus Explosion, Explosion.

　With a tremendous explosion sound, the debris was blown to pieces. Wait, isn't that too much, Linse!

We're all done here.

　While I was dumbfounded, Lindsay quickly began to investigate the area where the debris was located. What is this enthusiasm?
　When I stand at the place where the debris was, I feel even stronger. Down here.........?
　Nothing on the cobblestones beneath my feet... hmm?　What is this?
　A part of the cobblestone pavement was missing and we could see something underneath. I called out to the others, and as I moved the stones one by one, I found that it was a double door made of iron, about the size of two tatami mats. What is this place...?
　We worked together to open the doors. For some reason, the doors were not rusted and opened easily. Maybe it's not iron.
　And underneath it, a stone staircase leading to the basement greeted us eerily....
