From the description, it seemed that the sword had been gifted to the Earth Dragon by a skilled blacksmith, and its grade was at Peak-Level King Grade, capable of severing a Peak-Level Seventh Stage Expert with almost no difficulty.
Although the formation was still there, there wasn't anything that warranted it to be active because the sword there had already been taken. Only its projection was left there, maybe as a form of remembrance but who knew?
'Isabella has it... Huh?' Davis pondered as narrowed his eyes, 'Did she even tame it in the first place?'
He shook his head. It was unlikely for an expert who had just entered the Seventh Stage to subdue a weapon that was at the Peak of the Seventh Stage.
Or maybe, he was entirely wrong and someone before Isabella had taken it away, someone from the previous generations from the Ruth Family.
