520 Monsters can be good

Eisen looked at the space in front of him and raised his brows. This seemed pretty interesting, really. The old man stepped inside of the storage space and could feel the texture of the floor changing to the wood that this space was made of.

Even when Eisen extended his hands toward the walls, they were really there, as if he had just placed this box somewhere in the open. It seemed a little bit unwieldy, though. Maybe Eisen could play around with this some more later.

For now, the old man grabbed a mana crystal out of his apron and placed it onto the ground before stepping back out of the storage space. He quickly made it close, and the 'Box' shrunk down until it disappeared from Eisen's sight within just a moment, taking the mana crystal with it.

When Eisen opened the material storage again, the mana crystal was in the same spot that it was when Eisen closed it.
