During a surgical procedure, women undergo the removal of their ribs, which are then uniquely crafted into musical instruments. The smooth, polished surface of the bones is intricately carved and fitted with strings, producing a chilling and haunting sound, reminiscent of an ancient ritual. The eerie notes of these rib instruments can only be heard at night, when the women who had the surgery play them, creating a spine-tingling atmosphere. The sound echoes through the darkness, adding an air of mystery to the night. This unusual practice has been rumored to exist in some cultures throughout history, leaving a trail of intrigue and curiosity in its wake.
