Broken! I Slept with the Sickly Princess and Became a Taoist Couple!

YanderePrincessSingle Heroine I, Lin Yuan, am the tombkeeper of the imperial mausoleum, and I specialize in sleeping with the coffin board. In the middle of the night, the coffin board lifted up on its own, and a woman with fever all over got in. It's not a ghost, it's the murderous eldest princess of Dayu. She pinched my neck and said, "Cure my love-burning curse, or I will castrate you." I was about to say no, but the broken coffin in my dantian suddenly came to life. It crazily absorbed the power of the curse on the princess and fed me ten years of cultivation. What's even more terrible is that the system pops up: [Congratulations to the host and the Tianpin Furnace for completing dual cultivation, the cultivation level is +999. Warning: The other party's personality label: yandere/tsundere/severe possessiveness. You can't run away. The next day, notices were posted all over the city: a reward was offered for the flower picker who broke into the imperial mausoleum last night. Her Royal Highness the Princess personally supervised the trial. When she glanced at me, she sneered: "That tomb guard, why are you shaking?"
