The Black Dragon

Derek hovered on the battlement, a dark and imposing figure, the blood sea swirling around him like a malevolent dance. The crimson liquid twirled in macabre unison, responding to the Sin of Greed's silent commands. Alex and Lu Jin, undeterred, pursued him with unwavering determination.

Lu Jin, a flurry of motion, charged forward with six swords orbiting him like ethereal sentinels. The blades tore through the air, leaving behind dazzling trails of white light as they ruthlessly descended upon Derek. Each blade vibrated fiercely, resonating with a power that seemed to cut through the very fabric of reality.

Derek, seemingly unfazed, snorted disdainfully. The blood sea, moving on its own accord, answered his unspoken command. It surged forward, forming a formidable wall of blood to intercept the impending attacks. The clash was imminent, and the air quivered with the tension of their celestial confrontation.
