"Sign the papers, Serenity. I don't love you." Those were the last words Jackson said to me before he threw me out of his villa. He chose his first love over his pregnant wife. I left with a broken heart, hiding the secret of the twins growing in my belly. Five years later, I returned as a top jewelry designer. But why is my ex-husband blocking my way, looking at my children with red eyes? "Serenity, are they mine?" I smiled coldly. "No, Mr. Billionaire. They call another man Daddy now."

"You saved my life, little physician. That means it now belongs to me." Lin was the top forensic pathologist of 2026. Cold, brilliant, and untouchable. But after a bizarre accident, she wakes up in the brutal Great Yan Dynasty—kneeling in a pool of blood next to a freshly murdered corpse. Before she can even process her time-travel, the door is kicked open by Yan Guichen, the terrifying Prince Regent known across the empire as the 'Living Yama' (God of Death). He is ruthless, devastatingly handsome, and his bloody sword is instantly at her throat. To survive, Lin does the unthinkable. She uses her modern medical logic to prove her innocence, even daring to hold her silver scalpel to the deadly Prince's neck. Intrigued by her audacity, the Living Yama doesn't kill her. Instead, he forces her into a dangerous contract. She is dragged into his heavily guarded manor, forced to become his personal surgeon, his alibi, and his closely guarded secret. He is poison to her logic. She is the only cure for his cursed wounds. As deadly royal conspiracies close in, Lin finds herself sharing a carriage, a manor, and sometimes even a bed with the most dangerous man in the empire to keep him alive. She can dissect any corpse and solve any murder... but can she decipher the fiercely beating heart of the God of Death before it entirely consumes her?
