Battle of Giants VI - What is that thing...?

I just watched in joy as the expression of the wyvern turned from relief to pride and right back down to immediate despair. 

The scene was so satisfying that I had almost forgotten about the mind crippling pain surging throughout my body, alongside the cracks that keep becoming wider the longer I did not use any mana.

However, right now I was currently pouring all my mana into the fire explosion spell that I had created a few years back that could probably create a hole 1000 meters in diameter, yet now this one was dyed white with the color of the light element. On the other hand, I held an unstable azure flame that circulated with the power of wind, fire, ice, and electricity constantly being pumped with an enormous amount of mana.

Simultaneously, the expression on my face softened from its stiff self while the cracks on my body finally started healing faster than they were being created.
