The square door opened slowly, revealing a small cabin. The cabin looked exceptionally delicate and contained a few expensive-looking glass cabinets.
Inside the transparent glass cabinet, there were treasures. Among them, Merlin could see a Runic Magic Disc the size of a washbasin. After all, the Great Wizard Fidel was a master of runes, and the Runic Tower had been built to nurture genius Spell Casters who excelled in runes.
This Runic Magic Disc was extremely invaluable as it was handcrafted by the Great Wizard Fidel himself. It would not be found even in the Resource Tower.
Besides the Runic Magic Disc, there were also some precious Runic Magic Circles that, if arranged correctly, were capable of killing even a Seventh-level Spell Caster!
