This was the sound of magic power trembling.
At this moment, the vast, seemingly endless magic power within Shien's body began to tremble and circulate at high speed.
It kept accelerating.
It kept burning.
As though an invisible force needed it to drive it into existence, it was being consumed at an accelerating rate, turning itself into fuel, into nourishment, and drawing that power forth.
The amount of magic power required to activate this power was astonishing.
Even activating it at its lowest threshold required an enormous expenditure of magic power.
Even Elves, who were naturally gifted with magic power, likely could not afford such consumption. Unless one possessed magic power on the scale of Roxie, the Kingdom's Treasure, or Sophie, the Elf Queen, one would ultimately be unable to bear it.
Even Shien discovered after trying it that his own magic power could not sustain the activation of this power for long.
This showed just how terrifyingly intense this power's consumption of magic power was.
Fortunately, the strength of this power was also determined by the amount of magic power consumed.
If he activated it at maximum output, the sheer amount of magic power it required meant that even Shien could only maintain it for around ten minutes.
But at that time, Shien's strength would increase tenfold. Other than his magic power, every other aspect of him would be raised to ten times its original level, which was exceedingly terrifying.
If he only doubled his strength, though it still consumed a tremendous amount of magic power, Shien's reserves were more than enough to sustain it for an hour.
Shien had already calculated it. Without taking the Holy Sword or this power into account, his combat strength in his normal state was roughly equivalent to the limit of mortal
