As the man finished speaking, he pulled out a key from his pocket and tossed it toward Raven.
"You can use this key to open the sixth floor but only once. That is, if you reach there."
After handing over the key, Orien left in the opposite direction to the Tower of Skills, leaving Raven behind.
Raven watched Orien's retreating figure until he disappeared from sight. He gripped the key tightly, filled with curiosity as to what awaited him on the sixth floor.
He didn't know much about this city, other than the things he had heard from others. In those things, there was a mention of the tower of challenges but there was nothing more than that.
He didn't even know what kind of challenges he was going to face in the Tower or what he had to do to pass the test. Still, he was certain of one thing. One could receive great skills based on their performance inside the Tower.
