[i]As a descendant of the ancient dragon, Dr. Gyy's body has super flexibility, with a spine structure of over 50 pieces that allows her to twist her waist freely. In order to support such a flexible body structure, her strong ligaments and muscles throughout the body require frequent stretching training. Don't worry about excessive flattening and twisting affecting her normal breathing. Her powerful ancient magic and excellent breath holding ability support her to engage in non-human twisting activities for a full five hours.[/i]
