In the heart of the chamber, the towering black dragon surged forward with an indomitable force, its immense form cutting through the hazy air. As it propelled itself with relentless power, a volley of wind bullets descended upon it, a futile attempt to halt its advance. However, the dragon's obsidian scales, impenetrable and resilient, repelled the projectiles effortlessly, rendering them ineffective against its mighty hide.
With a resounding roar that shook the very foundations of the chamber, the dragon's dark green flames roiled within its maw, gathering an intense and formidable energy. Its colossal neck expanded, a testament to the sheer might and power dwelling within the creature.
A surge of raw power surged forth from the dragon's jaws, a torrent of fierce dark green flames coalescing into a searing beam of destruction. The beam surged forward with unstoppable force, hurtling towards the imposing doors at the far end of the battlefield.
