Marius confronts an enemy sent by William Ross to kill him inside a dungeon. Despite the opponent using a Null-Magic Scroll to disable active skills, Marius reveals he relies not on skills but on his S-rank Berserker Physique, making the scroll ineffective against his raw strength. Their brutal fight escalates as the enemy admits underestimating Marius and vows revenge. The enemy then threatens to destroy the entire dungeon to eliminate Marius. Suddenly, a critical warning announces the awakening of an Abyssal Dragon, escalating the dungeon’s difficulty to nightmare level and forcing Marius to face an even greater threat.
