This was important. He had to find the Crazed Swordsman to clear the Quest of this Floor.
The Crazed Swordsman wasn't a player. Instead, he was a native of the Tower of Demons. From Raven's perspective, he was something like an NPC, albeit not quite since this world wasn't a game. Instead, this world was a reality.
Everyone who went to the next floor had to fight the Crazed Swordsman and last at least one minute in the battle. That was the only requirement of the Quest of First Floor.
Even though this looked simple, thanks to the memories, Raven knew how hard it was. The reason most of the people here hadn't cleared the Trial of First Floor was because they were scared of the Crazed Swordsman.
It was said that only a fraction of the power who challenged him ever survived. Let alone lasting one limit, even surviving ten seconds was an almost impossible task for many.
