One Injection Saved the Female CEO, but She Actually Used Me as the Antidote

With a sky-high price contract, I became the "antidote" for the female CEO of Bingshan to continue her life. During the day, she was aloof and bossing me around. At night, she was cold all over, curled up in my arms, greedily asking for my warmth, begging me over and over again: "Don't leave..." She doesn't know that every intimate contact that "extends" her life is consuming my life. She doesn't even know that my ancestral precept is to kill her with my own hands!
