[WHAT…?]
Isaak was surprised when he lost Runa, even though he was just running closely behind her a few seconds ago.
But his daughter suddenly disappeared.
And now, he was standing alone in front of the "maze."
It was a maze on the surface, but there was actually a secret garden inside that only the members of the royal family like him knew and had access to. However, when Empress Liane died, his brother Emperor Rino destroyed the secret garden because the emperor didn't want Empress Veronica to have access to it.
After all, the secret garden inside the maze was Empress Liane's favorite place.
[Did Runa enter the secret garden?]
There was one way to find out.
He put his hand on the maze's outer wall, then he hit it with a soft wave of his Mana. Every member of the Royal Family had a unique layer of Mana that the secret garden would recognize. Thus, he could open the maze using that.
