If the problem was the durability of the weapon, then Eren believed that this problem could easily be solved by using something that had extremely high durability.
Even if the Overlord Killing Dagger was incomplete, it was still a legendary tier weapon. Even more important was the fact that it could not be linked to his other identity.
The only people who knew that this dagger was in the hands of Ren Necroline were dead or slaving under him.
Even if it was incomplete, Eren could still feel how extraordinary this dagger was the moment he held it.
It truly made him wonder just what kind of weapon it could become if it was ever completed. Unfortunately, only the Holy Priestess knew the process to complete this dagger and she was not kind enough to tell this to outsiders.
Eren firmly held the Overlord Killing Dagger firmly and thrust it down, striking first at the shackles that were keeping the Sea Dragon Empress' mouth sealed.
