The Resounding Voice in the Soul

As soon as Meredith and Wanney started running towards a large rock that was near them, the giant dragon's eyes

followed them. 

The pair of horns on top of the dragon's head glowed for a brief instant as it opened its mouth. In the next second, a long blast of dark energy began to spew from the monster's mouth toward the fleeing duo. Dragons were too proud creatures to let victims escape unharmed.

Luke propelled himself forward with speed, and hit the dragon in the jaw with an explosive punch, in a move so fast that even the dragon could not predict it.

Luke's blow was so powerful that it stopped the dragon's attack.
