Shikkakua Mon no Saikyou Kenja~ Sekai Saikyou no Kenja ga Sarani Tsuyoku Naru Tameni Tenseishimashita~

A completely wasted s.p.a.ce architecturally speaking .
Located around the center of a building .
And . . . All the areas surrounding this s.p.a.ce cannot be entered by anyone .

"It"s suspicious all right . . . So, think the sword is in there?"

"At the very least, I"m sure it"s hiding something . "

Ruli glared at the map .
Then she drew a line .

"Breaking walls on this line nets us the shortest route to this suspicious s.p.a.ce . . . But these walls seem to have been deliberately reinforced, don"t they?"

"Yeah . Good eyes . "

"Because they"re using some unusual building materials . . . "

Ruli is correct, the walls in the shortest route have been reinforced .
Advertis.e.m.e.ntThey"re made of an abundant amount of stuff like Mithril, rare in this era, and expensive building materials like steel .

The construction seems recent too, and we"ve even found traces of processing by way of magic .
There are also other miscellaneous marks of reconstructions in the mansion .

Since the [Coffin of Sealing] where the [Man-eating Blade] sleeps can"t be moved far, they must have no choice but to build a house that"s easy to protect to keep the Coffin hidden away .

"Mere st.u.r.dy walls can be destroyed any time . . . Our problem in this case is the demon itself . "

Even if we make Iris break the walls, it will still take us around 10 seconds to get to the hidden s.p.a.ce .
It would take less than 10 seconds for the demon lurking in the mansion to make its way to us .
We can"t avoid fighting either way .

" . . . We should cook up a plan while scouting the demon"s strength . Let"s go to the lord"s mansion once again . "

"Got it!"

"Yes!"

The girls stood up .

Then just as the three were about to leave the room I told them .

" . . . Also, careful not to use Comm magic until after we beat the demon . "

"Is it because it could be tapped, like when we fought Grevil-sensei?"

"Yeah . Comm magic transmits out mana . They"d suspect us . "

◇

A few minutes later .
I investigate mana reactions outside the lord"s mansion .

"It"s hiding really well . "

I murmured while looking at the surrounding mana .

"I don"t sense even a tiny bit of mana that fits the bill . . . Mathi-kun, can you tell?"

"I can . Of vestiges of magic used by demon rather than the demon itself though . "

I couldn"t see the demon"s mana itself even after getting this close to the mansion .
The only demonic things I could sense from here is vestiges of mana from when the demon used magic and stuff .

However, you can guess a demon"s strength by such vestiges .
But you"d need a proper a.n.a.lysis and enough amount of mana as sample . . .

"Oh found it . "

I"m paying attention on walls surrounding the town lord"s mansion .
There were traces of a recent repair on the corner of the walls .

I feel demonic mana from that repaired part .
The demon must have done the repair itself .
And . . . Magically repaired walls are a treasure trove of mana sample .

I put my hand on the wall . . . and a.n.a.lyze the mana .

" . . . No wonder it"s "Greater", this demon is pretty strong . "

I managed to guess the demon"s strength from the mana reaction .
It"s weaker than Zaridias . . . But it"s the second strongest demon I"ve encountered after reincarnating so far .

It"s not like I can"t fight it head-on . . . But winning would prove difficult .
It"ll most likely turn into a stalemate where we both attempt to exhaust each other"s mana .

If it comes to that, we"ll be in a huge disadvantage .
A demon has a far larger mana pool than human .
We need a plan to win .

As I was thinking that . . . I sensed one mana reaction among many in the town rapidly approaching .

This mana, it"s Giruas .
Looks like he found us out .

We could shake him off . . . But this is a good timing .
It might even be the breakthrough we need .
