Chapter 61


Chapter 61 Strongest Sage, Uses Up Mana


" . . . Keeping silent won"t help you . Even if you"re invisible with naked eyes, you"re plain as day with that much mana emitting . "


" . . . Mathias, could it be that there"s a demon inside this castle?"


The king sounded surprised when he heard me .


"No, it"s not the main body . It"s a spell art unleashed by the demon . "


"Spell art . . . Is that some kind of wiretapping?"


"Something like that . You cannot see it, however--"


I took out a wood chip as I said that and threw it at the corner of the room .


The chip drew a parabola and got repelled as if it hit something one meter before the wall .


"Looks like it has a substance . Though, the demon won"t suffer any damage even if that"s physically destroyed . "


Judging from the spell art, it"s most likely a variant of magic called 【Fixed-type Simple Mana Interference】 .


It"s a relatively simple spell art which can be used to monitor far-away places .


In addition to that, it can also be used to turn up doc.u.ments and send voices .

Furthermore, it doesn"t have enough power to kill but conversely, the user also won"t receive any damage even if the spell art is attacked .


In a way, it"s a magic with an extremely good cost/performance .


"I can"t believe it . . . . "


The other three beside me seem to be shocked .


And the demon ("s magic) doesn"t look like it"ll make a move either .


Well, that"s probably the correct answer for the demon . You can"t really tell it apart from simple barrier magic as long as it doesn"t let out a sound .


--That"s why I"ll make it speak .


This spell art has two weaknesses in exchange for its low mana consumption .


First, it needs time to set up, and the range is quite narrow .


It"s not very effective unless it"s set in a room where extremely important conversations are carried off .


As for the other weakness, I use up all my remaining mana and construct a very small-scale magic .


"Guh, what the heck is this . . . . "


Right after that, a perplexed voice resounded from the corner of the room .


You cannot damage the user of 【Fixed-type Simple Mana Interference】 through the spell art .


However, that only applies to physical damage and simple destruction through magic .


The information gotten from 【Fixed-type Simple Mana Interference】 is processed in the spell art user"s brain .


In other words, if you forcefully send harmful info for a demon mixed in the actual info, it"s possible to directly destroy the brain .


"GU, GUAAAAAAAAAAA!"


The spell art broke along with anguished voice, and the s.p.a.ce in the corner of the room warped . Apparently the spell art didn"t have emergency cut-off function incorporated, however the magic itself is disintegrating as the demon loses control over its own mana .


I supported the spell art for half a second using my remaining mana before I ran out of it .


The spell art that lost its support disappeared with a clank sound .


" . . . Did you kill it?"


"No . It"ll leave an aftereffect somewhat, but the demon probably hasn"t died . "


Even if I have my usual amount of mana, it probably won"t still be enough to kill the demon .


The user would have been killed if it was a human, but a demon"s brain is st.u.r.dier than that of a human .


" . . . I see . My grat.i.tude for your help . To think they even slipped into this room . . . . "


"About that matter, Your Majesty . Did the voice earlier sound familiar to you?"


"Now that you mention it, that voice was . . . . of the previous Magic Division Commander, Elhart!"


Thought so .


"Did Elhart ever come into this room?"


"Many times . He got us during those times huh . . . . "


Then we can safely a.s.sume that the culprit is Elhart .


He probably could set up as many similar spell art as he wanted since he was against humans who couldn"t even use 【Pa.s.sive Detection】 .


"For the time being, I will set up barrier that can intercept wiretapping magic on important rooms like this one . "


"You could do such a thing?"


"Some magic can"t be intercepted, but it"s better than nothing . "


That said, such magic are all complex magic, the present demons highly likely can"t use them .


If I just put a warning system for when the barrier is destroyed on it, I"m confident I can deal with it .


Ruli will be the one who does the augmenting though .


"By the way, 348 kilo to the west from here, and then 4425 kilo to the north . Do Your Majesty know what"s located there?"


" . . . Hold on . "


The king took out a map from a drawer .


"It"s still inside our kingdom, but there is only a remnant of an abandoned village destroyed by demons in the past around that area . . . . Don"t tell me, Mathias . . . "


"Yes . Looks like we"ve found the demon"s location . "


Using such a poor monitoring magic in front of me would only result in getting traced back instead .


Now then . It"s a bit far, wonder how should we go around to attack them .
