Raina looked at the huge fortress in for of her with an intense stare. She was observing the headquarters of the Order of Purple Sun so that she could get her cannons to work and break down those fortified walls.
At her signal, the warship she was riding slowly turned to the left, exposing its side to the stronghold atop the Purple Sun Hill. With its sides also came the Hell Hammer cannons mounted on its deck. The warship she directly commanded was located at the front of the formation. Looking back, Raina also saw the other four flying warships at the back mirroring her warship's actions.
To be honest, the step by step of the process was a simple thing. Pointed the Hell Hammer cannons in the direction where you wanted things not to exist. Then, gave the order to fire and watched as the explosions destroyed the offending structures and reduced them to ash and debris.
