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.
As the dagger came in contact with the shackles, there was no sound. It was as if something had struck a void where all noise was devoured. Eren didn't even feel any resistance as he struck, unlike what he felt when he used the previous dagger.
Despite no resistance, the shackles did take a massive impact. Cracks started spreading throughout the shackles before the shackles keeping her mouth restrained shattered into thousands of pieces.
With the shackles gone, the Sea Dragon Empress spat out the gag that was put in her mouth. Meanwhile, Eren continued striking the shackles around her hands, feet and legs.
He was extremely careful when striking as a little mistake and he might actually slice her limbs off.
Fortunately, in his caution, he did not miss even once. One after another, the shackles kept breaking their pieces disappearing into nothingness as they returned to their original form of holy essence.
....
As the shackles broke, the Holy Priestess felt slight pain in her head. The glass of wine in her hand fell to the ground as she looked back, her expressions darkening.
While a group of criminals were distracted by the beauty of the Holy Priestess, there were also others who were more interested in running away. They did not want to put their freedom on the line for a mere woman, no matter how beautiful she was.
"Tsk, what cowards. With so many of us here, do you still worry about a mere Archbishop? It's not as if he is the Holy Pri-" the man spoke arrogantly, but before he could finish his sentence, he felt a pain around his neck.
His head slid to the side as his head was sliced with the holy essence. He wasn't the only one. Even the ones who were running away faced the same as their bodies froze while their heads rolled on the ground.
This level of strength, there was no doubt in their mind about the woman's identity anymore.
"Priestess...?" The man who talked about tasting the Holy Priestess could not believe his bad luck even as his head fell on the ground with life sucked out of his eyes.
The Holy Priestess did not move but her emotional turbulence was evident. She had received one shock after another today, the freedom of the Sea Dragon Empress was the least of which.
More concerning was the fact that she had seen Devourer! She had only heard rumors about his appearance in the Southern Continent but he had thought that it was only an exaggerated rumor.
Now that she saw with her own eyes, there were no doubts about it. It was Devourer.
The most shocking was still the fact that he was holding the Overlord Killing Weapon that she has created to kill the other Overlords in the future.
When it disappeared, she was certain that it was the work of other Overlords. Without her, they couldn't complete it. Hence she didn't lose her sleep over it. But it was Devourer, then he actually didn't need her help to complete it if he knew the right way.
For the first time in a long while, she felt a throbbing headache.
"How could he enter the Holy Domain without me noticing? Until he was already inside?"
That was also a thought that appeared in her mind, her gaze turning towards Eren's room. They were the only outsiders that she had brought inside her Domain.
