"Boom!!!"
With the launch of hundreds of giant magic-guided cannons, the earth-shattering roar seemed to explode directly in everyone's ears, even from such a distance.
The entire Iron Curtain Wall shook violently, and an unimaginable explosion occurred within the breach.
Visible shockwaves erupted from the breach, instantly pulverizing everything nearby, whether defenders or slave creatures, into dust.
Massive clouds of smoke and fiery mushroom clouds rose into the sky, as if the gates of hell had opened on earth.
It wasn't over yet, as the main cannons of three destroyer-class battleships above the clouds completed their final charge.
Three thick, mountain-like azure energy beams descended from the sky with divine retribution, silent yet as fast as lightning, precisely hitting sections of the Iron Curtain Wall where defensive runes were most concentrated and where the command nodes of the defending forces might be located.
