Dragon roar?

Dragon roar? What the heck was she talking about?

Liam was already at his limits so he did not have the mental space to think about the random words of advice. 

He continued to push himself and used the full extent of his mana core and his soul to attack the frozen creature.

On the other side, the draconian princess did not let up. She continued to shout at him the same thing over and over.

"Don't hold back now. This is dangerous. Finish the fight quickly. The Ison King might have some other dormant ability. Use your draconic breath. NOW!"

"Foolish brat! Use your dragon breath!"

"Just let it rip! What are you waiting for?"

The woman was practically hissing in anger at this point and Liam continued to ignore her as he still had no idea what she was talking about.

And then it happened.

The two of them simultaneously realized something!

What if he did not know he even possessed this ability in the first place?
