Marius faces off against an enemy who believes his Null-Magic Scroll can disable all powers, but Marius reveals his S-rank Berserker Physique remains unaffected, allowing him to fight without magic. The enemy, sent by William Ross to kill Marius, grows frustrated as their tricks fail. As the confrontation escalates, the enemy threatens to destroy the entire dungeon to eliminate Marius. Suddenly, a critical warning announces the awakening of the Abyssal Dragon at Nightmare difficulty, intensifying the battle and forcing Marius to prepare for an unimaginable challenge ahead.
