For a second, there was total silence on the battlefield as everyone came to terms with the horrifying sight before them. More than 3,500 level 50 Rank 1 NPCs had been turned into dust as they had been hit with an undefendable sound-based skill.
This baffled the onlooking players and the surviving NPCs greatly. They couldn't understand how such a skill could dare to exist in the material world.
Players belatedly noticed that they weren't affected the skill, but enemy monsters and NPCs who encountered it would be severely damaged if not outright killed. If the range of the Black Dragon's Roar hadn't been adjusted, Draco would have killed every NPC on the field.
Even though the shock was mind-numbing, the fighters of either army didn't stop the battle. The players who were part of the regiments that lost their NPCs were given quick and astute commands by the two guild leaders to join up with Regiments that still had NPCs to reinforce them.
