Capítulo 648: The War Resumes!

In the Awareness, Merlin's Four-Elemental Wizard Heart was like a giant overlord, suspended in the middle. Only two Wizard Hearts were left. 

These two Wizard Hearts was the most difficult to fuse as well as the most unexposed, compared to the other four which had previously been components of the Four-Elemental Spell Fusion. For Merlin to fuse these two types of Wizard Hearts, he would have to run simulations for a very long time. 

"Phew…" 

Merlin exhaled deeply. A thought flashed through his mind. "With what I've achieved so far, I wonder, compared to the Seven-Elemental Wizard Nelar, who would be stronger?"

Merlin had a very deep impression of Nelar. Throughout the history of Spell Casters, only one Seven-Elemental Spell Caster had existed. Moreover, Nelar had thirty perfect-grade spells, only six less than Merlin.
