'Opening them won't be as easy as how I opened my disciple's...' Aimon thought as sweat flowed down his wrinkly face.
It seems that it was really something heavy and hard as Aimon was aware that the 10 golden needles were made with Aurus Gold.
In fact, Aimon specifically used these 10 golden needles in order to help him with the task of using the Divine Sharpness of the Ghost Needles.
The 10 golden needles, Divine, would be used with the qualities of the Aurus Gold.
Surely, something such as a magnificent metal as Aurus Gold would be able to lessen the burden of opening the locked doors in a human's Spiritual Vein.
However, even though Aimon knew that the Divine was literally divine, he knew that it would be hard.
He knew that not even the Aurus Gold would be able to help in opening Desire's locked doors.
