My Brain Was Transplanted into Her Royal Highness the Princess

Li Yuming had meant to disguise herself as a girl, but her brain was transplanted into a princess of the dynasty instead. Then an unparalleled immortal maiden who looked exactly like her chose her as a double.

"While I am in seclusion, you will impersonate me and deter our sect's enemies. You absolutely may not leave, not even for a moment, without my permission."

The unparalleled immortal maiden tried to keep her precious beauty hidden away.

Who could have guessed that just a few days later, Li Yuming would seal the immortal maiden's cave dwelling shut, turning the tables and keeping her hidden away instead? Even worse, she captured more immortal maidens and demonesses and tossed them inside.
