Boundary Labyrinth and the Foreign Magician

We descended the Sirius and moored it in the courtyard. I'll get down to the Royal Castle of Nahalvia as soon as possible and see what happens to the Royal Castle again.

... were you talking about the upstairs being swallowed up by darkness and wiped out? The whole royal castle is gone until the part that hits the ceiling on the ground floor, and the stone floors that would once have been polished out are also covered with thick sand and dust.

There are no signs of any other attacks. It means the guy who did this just wiped the upper floors of the Royal Castle out of the middle with one blow.

And it won't be a simple explosion. This is exactly what we talked about. There are no signs of debris or fragments scattered around.

"I… will speak to the guards of the Old Capital"

Princess Elkham said. Although it has a rugged look, there is no weak impression. Leaving this place would also be more to do what you have to do than because you don't want to see the ruined royal castle.

"Okay."

"If you don't mind, we'll hit the escort."

"So long,"

The faces of Mercedia, Elmer and Lionel were attached to Princess Elkham's escort. Hmm. Shall I accompany Cadkeus for once? I've kept track of the other exchange.

"Okay, I'll be there"

Drop off Princess Elkham and the Knights of the Summons and find out more about whether there are any underground passages or other loopholes.

Hidden doors and more are specialties of Sheila and Serafina. Underground aisles are Corliss' specialty... but don't let the erased parts get too big. I wonder if the records, materials, etc. are also missing.

As we walked around the ruins and made 3D models out of dirt magic... traces of destruction became easier to understand.

"I knew it. The deeper the attack reached the center of the castle, the shallower the attack is going to the outer edge."

When I say that, everyone peeks into the 3D model. If you look at the walls, ceilings, columns, etc. left everywhere… you can see how much range was attacked by the burst of a spherical attack on the upper floor of the castle. He said the part covered in darkness was gone, and on the contrary, it can be seen that it would not be greatly affected if it were outside the scope of the attack.

If I could make a model of the sphere while adjusting its size and put it on top of the 3D model of the castle...... it fit perfectly in the trail of destruction.

"If an unknown king was coming to the royal castle... does that mean he was near the center of this sphere?

"... I see. It's easy to understand."

Mallane snorted as well, saying as Grace was impressed.

If you say anything about the blow that wiped out the castle... whatever the nature of it is, this will give you an exact range of attack. All you have to do is scale him out of the 3D model.

Given the damage that surrounds you if you become in battle with an unknown king, is that as good a reference as choosing a place to fight? He seems like an over-attack guy, and there's no harm in collecting even trivial information. I'm not talking about getting hit before I cut it off and put in place measures.

"Corliss has a space in the basement... no, maybe this is the aisle. Yeah. I think I found an underground passage."

says Princess Stephania. Corliss, who was tapping and exploring the ground with his fingertips, is waving and signaling. Claudia laughs bitterly at the sight.

"I guess I should. Though I thought the Imperial Castle would have one or so secret ways out."

"So did the Castle Fort tracks used by Kahal and the others."

A similar mechanism would not be strange to have in the royal castle.

"But the hidden passage itself will most likely have already been discovered."

And, Valentina.

"Considering that the top of the castle has been blown away"

Old Siegmund closes his eyes unfortunately.

"Do you mean the passageway leading to the underground passageway is completely visible?"

"Right. There will have been a search for the survivors after the incident, and I think we've found the entrance and exit."

Princess Adriana answers Ashley's question. Indeed. If it means that you are currently banned from entering the abandoned castle, then naturally the exit side of the hidden passage will also be blocked.

"I wonder if we should still explore it. I can't even investigate the top part of it that's gone, but I might be able to find an undiscovered hidden room."

"I agree. Hidden passageways are invisible, so if you were to hide something important, I'd choose it. That's what happened in Verdogal."

Rosemary says as she hides her mouth with a feather fan. Rosemary also discovered a forgotten hidden passage from which she obtained a magic potion and a magic trick. Does that conclude from experience?

Well... so was my mother's house.

"Sounds like you should wait for Princess Elkham to come back. Unless you're connected to the Royal House of Nahalvia, it's possible that it won't open."

After all, destroying the structure itself... is not a sneak idea. Sure, the royal castle has been destroyed, but I don't even think that's why I can break it any further.

If you look at Princess Elkham in Cadkeus - there was no particular big trouble, and it was an occasion when a few or fewer of the guard captains who received a letter from Fatima were dropping Princess Elkham off in salute. Apparently, he was the one who knew Princess Elkham. I think maybe he's a Nahalvian associate.

I don't know what the Old Capital is... it looks like a pretty lively place. There seems to be open-air merchants in pedestrians, even liquor stores in stalls, and there are quite a few street streets. It seemed like people were gathering for the business of adventurers like it was a trade in materials that could be picked in the woods. There's also water. Is it also natural that if people get together, it will be developed as a base? Originally, the house would have stayed the same.

Whatever's going on in the city...... we'll have Corliss follow us to the part that will be the entrance to the underground aisle by the time Princess Elkham gets back.

And - when I told Princess Elkham about it quickly back from all over the city, she nodded quietly.

"I don't know if I can help you."

… and that is why it is an underground passage exploration. As we went down the spiral stairs, we were able to descend straight into the underground passage.

The stone underground passage is dark and quiet. Let the magical light sphere shine ahead, followed by Sheila and Serafina going down the aisle.

It was when I checked every corner from the dark aisle ceiling to the floor and proceeded to the back there.

"Mmm. Wait."

Moving on, Sheila stopped moving. When I lift my arms and stop everyone from progressing, I look around the surrounding walls, floors and ceilings with a careful trick to make sure there are no traps, and then I look back here and say:

"I found something. This."

Below the wall Sheila shows, there was a carving like a small relief. In response, Princess Stephania closes her eyes and opens her mouth with a five-sense link.

"Now...... Corliss is checking the space around the other side of this wall from overhead...... I don't seem to know. He said he was shooting magic at me, but he didn't get back to me."

... If you say so, Sonar's reflexes won't come back. If you look closely with the monocular glasses, you can see that they are blurry and magical. Something... maybe even magic for cover up. Is this... a hit?

"There is no such thing as a physical trap... I think"

Sheila says as she checks around the relief.

"May I have a look?

So Princess Elkham came forward.

"Okay. If you see any signs of a magical trap activating, we will defend you."

Hold back right next to Princess Elkham and set up Uroboros, ready to deploy the shield immediately if there is a disturbing reaction.

"Thank you"

I'll give Princess Elkham a hand in relief... but that doesn't seem to make any difference. No... is the magic of the relief slightly shaken?

"May I have a moment?

"Go ahead."

I'll hold my hand... but I didn't have the same reaction as Princess Elkham did. After all, I'm pretty sure I'm responding to her magic.

Describing what she saw with her monocular glasses, Princess Elkham nodded and said.

"Would it be okay if I touched it?

"Right...... right. From the reaction, I don't think it's a trap."

It is the royal family of Nahalvia that uses this underground passage. So it's hard to think of a trap to fall the royal family of Nahalvia.

I'm pretty sure the reliever's magic is also responding to Princess Elkham's fingertips to touch... but there's no dramatic change.

"My time, though I reacted to the blood..."

And Rosemary said.

"Really? Okay, let's try it."

Princess Elkham slightly injures her fingertips when she pulls the knife out of her sheath that was sitting on her hips. I touched the relief intact with seeping blood.

At that moment. Light ran from relief to the wall. A flash of cut squarely runs onto the wall, and the stone on the wall that should have been there fades, and a staircase appears that leads further underground.

"Apparently, you were right."

Princess Elkham smiled happily with her short knife back in her sheath.

"His Highness Elkham. Hands."

"Thank you"

Ashley blocks Princess Elkham's fingertip wound.

"Well, shall we come?"

When I look at everyone and say, they snort, too. Well...... What's coming out of it?
