Practicing for an unknown amount of time, Zen was about to give up trying since there was zero fluctuation of mana flowing in the chimera corpse.
When the tall figure cast the Hymn of Death, there was dark mana looming around the corpse before it manifested into a shadow. However, Zen could not produce the same type of dark mana surrounding the corpse.
'What am I missing?' Zen scratched his head and tried to recall the process that the tall figure did.
Suddenly, like a thunderstrike occurred into Zen's head, he finally realized what he had missed.
'The timing of the chant and the corpse type.' Zen exclaimed inwardly as he became agitated.
He was only focused on the chanting part of the tall figure but forgot about the time when it paused for a while before continuing to cause the shadow to manifest into being.
