Chapter 50
Before challenging the 『Floor Master』, I investigated the monsters and the terrain here with 【Passive Detection】 .
It's normally not possible to defeat a 『Floor Master』 alone .
If it was the past me, I could just shoot some random magic to evaporate the monster along with the dungeon from where I stand, but the current me has lower magic capability than even an average magician in my past life . I can't use that kind of brute force method .
Even with all of my knowledge and experience, I still need to plan a way to defeat it .
I'm going to pick a place to fight based on the flow of mana and terrain .
The battlefield has to satisfy two conditions .
First of all, there should be as few passages as possible that connect to that place .
One of the basic in challenging a 『Floor Master』 is to exterminate the whole monsters that dwell on that particular floor to prevent them from barging in during the fight .
However, I can't use that method this time .
The need to exterminate other monsters on a floor is applicable when it's a raid subjugation .
For me, doing that alone would waste too much mana and time . It's impossible .
Therefore, I'm going to narrow down a place with few passages that connect to it to decrease the possibility of monsters intruding in .
Even if other monsters barge in, I can just cope with it if I just anticipate them with 【Passive Detection】 .
Secondly, it has to be spacious .
The Fourth Crest is normally better in a narrow space, but when you're fighting a 『Floor Master』, not having enough space to dodge its attack is out of question .
After all, the current me would die if even one of the 『Floor Master』's attacks hit me .
--Fortunately, I immediately found a place that meets those conditions .
It's a huge room 80 meters away from the place the 『Floor Master』 is lurking .
I went into that room while cutting down all monsters I met along the way to reduce the chance of them intruding in even a bit .
The ground is flat, the ceiling is high, there are only two passages that connect to it . It's perfect .
And since I've gotten closer to the 『Floor Master』, I've completely grasped the kind of monster it is .
It's a huge venomous snake monster called 『Arch Serpent』 in my past life .
It's hard to treat it as a source of material, but at least I've gotten ahold of its identity .
--And so .
"Now come!"
I invoked 【Compulsion Detection】 at the 『Floor Master』 while shouting out loud .
In order to make the Arch Serpent separated by several layers of walls, dozens of meter away notice me .
Then I heard roaring sounds from the direction of the Arch Serpent .
Using 【Passive Detection】, I see that it's coming straight at me through the shortest route while ignoring walls .
And about two seconds later .
The wall in front of me suddenly dissolve as the Arch Serpent showed itself along with purple liquid .
The purple liquid is an Arch Serpent's most peculiar characteristic, it's a strong acidic venom .
The venom isn't stopping at only dissolving the wall as it begins to gradually dissolve the floor which should have been far resistant to acid .
" . . . . Oy oy . There's a passage over there, use that instead of breaking things please . . . . "
Now a terrain I've especially prepared for the battle is ruined .
I can't rely on the ground at least .
My shoes will melt if I step on the ground where the venom fell, and even if I have acid-proof shoes on me, those hollowed grounds are useless as footings . Even if the surface looks fine, it's not unusual for the inside to be hollowed out .
I can fight by putting up barrier magic under my feet for an instant as my footings .
And since the venom is volatile, it will pollute the air if it takes too long .
The air will only be safe for battle for at most 10 minutes .
Now then . It's the first tough-looking battle since I've obtained this Disqualified Crest .
Short it may be, let me enjoy this fight to the fullest .
