Alex's PoV:
The legendary rank 3-D printer was purposely built to have the exact model as the 3-D printer back on Earth but instead of using electricity, it used mana.
Moreover, the wires inside the 3-D printer were some mana veins that connected it to the mana core which was the energy source of the 3-D printer.
"Grace, how about you transfer some of your mana into the legendary rank 3-D printer and see what will happen?"
I suggested to Grace and she nodded in response.
Grace channeled her mana into both of her hands and touched the legendary rank 3-D printer.
After coming in contact with the legendary rank 3-D printer, Grace directed her mana into the 3-D printer which caused the mana core inside the 3-D printer to store the mana that Grace had imbued into the 3-D printer.
