The extreme fluctuation of Fire Elements on the black-robed old man was getting out of control. Tiny flames appeared on his body from time to time.
This was Wizard Hill's most critical moment. The Spell Models in his body would collapse at the slightest distraction.
However, the black-robed old man's Mind Power greatly exceeded the limit of an Entrance-level Spell Caster. His nearly peaked Mind Power even surpassed some First-level spell Casters.
It was exactly because of such extraordinary Mind Power, the black-robed old man was able to suppress the Spell Models from collapsing and survived until now.
"Wizard Hill, do you need my help?"
Merlin took the initiative to ask the black-robed old man who appeared unwell. After all, Merlin would have been in a worse situation if the black-robed old man had not risked collapsing his own Spell Models to interrupt Merilung who was casting Dark Mist.
