The Undying vs The Eternal Darkness

The crimson bolts of lightning were discharged and the power that ought to be wielded only by the strongest Gods was released at once.

Both Dilan and Kaeldur were burned to a crisp and the Devil, who had never voiced out his discomfort, let alone a sign that he was in pain, not even when his arms had been cut off, let out a soul-screeching scream that rang through the ears of the two Fate Changers. 

'How the hell is it possible for him to unleash such an attack?' Nial thought in shock while lifting his arm in response to the unbearable scream of his trusted companion. Currents of Chaos covered both of his arms and he released his chaos, ignoring the pain that spread through his body upon using powers he was not supposed to be able to wield yet.

'If you go all-out, I shouldn't hold back either!' He thought as the pain steadily increased, and he too let out a blood-curdling scream.
