Three Days

Unless they have extremely powerful people to protect them and had the means to rise in public… no one would be stupid enough to advance to rank 7 in the middle of the city. 

Aya thought about using the valley through her teleportation array that she had formed.

But when she came there, she found the ghost aura was extremely strong and the entire valley has been invested with ghosts.

So after taking one look, Aya immediately returned.

Unless she wanted to die, she would not go out and face so many ghosts.

As for how those ghosts come, Aya guessed that the world barrier in the area around the valley should be relatively weak. Even a ghost dimension space could appear there, what else could happen?

Well, Aya suspected that another dimension space had appeared.

But she didn't want to go there and deal with that mess.

It would take a long time and if she used a rank 7 magic… the cities nearby would definitely be alerted.
