The protagonist, a female emperor disguised as a man. She transmigrated from the 22nd century into the body of the original host eighteen years after birth. Originally a medical scientist from a family of practitioners, she died at twenty-five and her soul crossed over along with her medical laboratory. She can only open the space once a day and take out at most one item. The original host was born prematurely due to induced labor, leading to congenital underdevelopment. Consort Zhao fed her secret medicine since childhood to alter her pulse so imperial physicians could not detect she was female. She has no sense of smell, which is why she fell into the trap at the Palace of Benevolent Tranquility. At eighteen, she has never experienced a menstrual cycle due to hormonal disarray. She attempted to poison Shang Guanqi and later tranquilized a masked Shaman in the cold palace.
