The battle between Marcus and the Forgotten King raged on, each clash of their weapons reverberating through the ancient ruins. The Forgotten King, with his colossal form and unyielding strength, was an embodiment of raw power, but Marcus refused to back down. Every ounce of his determination, fueled by the System's enhancements and his own resolve, kept him standing despite the odds.

Marcus gritted his teeth. "You think I don't know that? Just keep the advice coming." His breath came in sharp bursts as he dodged another crushing blow from the king's massive blade. He was beginning to understand the king's patterns—his strikes were slow but devastating, leaving brief openings Marcus could exploit.
The Heartstone glimmered faintly in the center of the king's chest, a beacon of hope amidst the chaos. If Marcus could just expose it further, he might stand a chance.
