Even though it was only to open the door, why did using a single attribute take so much time? No matter how many of those spells of that degree were to be casted, using a three-section chant for one is too impractical…
Suimei seemed to be the only person shocked by such flawed magic.
All that was needed, to open even that unusual door, was simple magic. By converting magic power into an optimal state, one would only need to construct the barest minimum of magic formulas, and by invoking it, the same result would have occurred.
Even though that was all that was required, the guard had even went so far as to forcibly apply the wind attribute, and thus Suimei did not understand. Not only would it increase the length of the incantation, it would also increase the required magic power.
In other words, it was completely impractical. It’s common sense that such a spell wouldn’t even require chanting. If it was Suimei, he would only need to move a finger, and the door would have opened “by itself” in the same manner it had done so before.
