The Holy Sword of the God King is protected by a barrier, and it's not just any barrier, but the highest-level Twelve-Ring Forbidden Curse—The Isolated Avalon.
To break this forbidden curse, there are two challenges: First, it is like finding a needle in a haystack to locate the world coordinates of Avalon in the endless Western Universe. Second, one must have the means to breach the world defense barrier in a single strike.
Previously, Dorothy did not have these two conditions, but now she barely has some clues.
First, regarding the problem of locating world coordinates, indeed, without a medium, it is difficult to find. However, Sophia and the Lord of Glory sealed within Avalon are mother and daughter, creating a certain blood connection between them.
Of course, having just a medium is not enough without a method of precise large-scale searching, but Sophia possesses a pair of top-level Magic Eyes that can see through fate.
