Heracles did not attempt to communicate, and he felt no need to do so.
In the simple mind of mortals like Chaos, creatures like the Nine-Headed Snake were nothing good to begin with.
They could not communicate with humans, and even if they could, it would only be for deceit and lies.
Thus, upon hearing the roar, the young hero leaped up and headed in the direction of the sound.
"Come—"
"Demon, meet your death!"
Picking up the iron club he carried, Heracles struck down with one blow.
A kilometer away in the swamp, Hydra suddenly raised its head, staring at the human rushing toward it.
It neither dodged nor hid, lifting its snake heads to ram forward.
"Thud—!"
"Roar—!"
A muffled sound echoed, accompanied by the hiss of the Nine-Headed Snake.
Under the tremendous strength of Heracles, Hydra was momentarily battered and beaten.
But a Nine-Headed Demon has more than one head; even if one were lost, it still had eight unscathed.
