Immortal world orphan Li Muxue is reduced to a living medicine slave, suffering endless torture through blood extraction! Demon Emperor Ye Qingcang storms through the Nantian Gate, snatching her back from the abyss of suffering into the Demon Realm to become his sole personal disciple. Possessing peerless ethereal spiritual roots, she has long lived under the shadow. Demon palace veteran officials collectively object, hidden agents of the immortal world plot and poison her, and her family background and affections are ruthlessly weaponized against her. From trembling in fear to accept a bowl of milk porridge, to bloody battles in secret realms shattering divine demon fragments, the young girl undergoes a nirvana awakening with her nine-colored golden core. Facing the conspiracies and declarations of war from the immortal world, with a fiercely protective Demon Emperor backing her up and a sword ancestor senior holding down the fort, the former medicine slave will now stand upon the arena of the three realms and tear apart all those who ever bullied her!
