The Ghost King Dotes on His Dark, Poison-Wielding Seventh Miss

In her past life, she was the seventh daughter born to a concubine in the Prime Minister’s residence, but her best friend stole her identity, leaving her an orphan whom everyone could bully. At their first meeting, she encountered a noble and formidable gentleman, then mastered both medicine and poison, all to ensnare his heart. Her heart was carved out, her bones corroded, and her soul scattered. Only on the verge of death did she learn the truth behind the ruin of her life. When the dream came to an end, she returned to ten years earlier and unexpectedly unlocked a mysterious pocket dimension. Returning in glory, she would kill every faithless traitor and turn the world upside down! But… why was this cold-faced Ghost King always following her? Why did he want to marry her? Because she was the one he had chosen.
