After researching for a while, the Witch Demon Elder muttered to himself softly: "It seems like installing two identical arms isn't impossible, but they will definitely interfere with each other during movement, so it's better not to install them. The best method should be to install a more slender arm for auxiliary attacks from above or below.
To meet this requirement, the shoulder must have a protrusion as a connection point to install the new arm and connect the Energy Core. However, the internal energy transmission circuit, adjustments to the rest of the body, and the arm's shape are going to be quite troublesome..."
Scratching his head, the Witch Demon Elder spun around in place and stepped towards the main laboratory.
A short while later, he returned with papyrus, a quill, and an ink bottle in hand.
He placed the papyrus on the armchair, dipped the quill in ink, and began sketching.
