"What do you mean through a mysterious dimension, Aldred?" Saphira asked.
"When your father showed me his spatial spell, I saw something through the hole of the space. I was curious, so I studied at the school's library about space and dimension, and then tried to enter it."
"Then what happened?"
"I cannot exist in that dimension for long. If I stay there, I would be erased. But I found out that the distance is relative there. If I take one step forward in that dimension and return, I would be 10 kilometers away from my original spot."
"But, Aldred, teleportation spells can be blocked or be canceled," Stella said. "Diamond Ranks have a lot of treasures to do that."
Aldred smiled. "Not this time. The spell I used required high-level mana to execute, and this level of mana can only be found in mana crystal."
