Following the instructions, he arrived on the second floor.
There used to be a door here that couldn't be opened, but this time, when Roger arrived there, the original door had vanished, replaced by an iron door that was completely black and seemed to be embedded in the wall.
As soon as he touched the iron door with his hand, three scenes appeared before his eyes. He selected one with his thoughts, and his entire being sank into the door.
When he reappeared, he had arrived at another safe point.
"So that's how it is!"
"These four safe points, after being fully integrated, actually connect with each other!"
You could travel to any of the other three from any one of them.
A Cursed Land in a semi-finished state, such a place might not even be documented within the Hunters Guild.
For convenience, Roger assigned numbers to the four safe points.
From 1 to 4.
