The Hydra, the Undead, and the Magic Spells

Over the surface of the black lake, the incandescent Flame Blast fireball shot through the air in a long arc. It went past the black water droplets that formed after the Black Phlegm collapsed and the Firework released by the Hydra and hit right at the Hydra's body.

Boom!

It was another earth-shattering explosion. Regardless of its power, Flame Blast was one of the loudest spells among all the elemental spells.

The incandescent flame wreaked havoc to the part of Hydra's body where its six heads were connected. The explosion lasted for five seconds before it completely disappeared.

Under the explosive impact of Flame Blast, the Hydra's six heads looked confounded. The half-formed spells that they were about to unleash in their mouths were disrupted and then collapsed. Its colossal body also lost its balance for a while, and that caused it to wobble about for a few seconds before it could stabilize itself again.
