You Were Supposed to Bring Her Good Luck, but You Made the Princess an Empress

【System】【Single Heroine】【Alternate History】【Live-In Son-in-Law】【Play the Pig to Eat the Tiger】 Everyone in the capital knows that Li Cangyue, the Princess of Beiliang, is a ruthless madwoman who kills without blinking. And I, Su Zhe, am the unlucky man sent to her as a good-luck groom, the last surviving remnant of the Su family. On our wedding night, she pointed her sword at my throat. I only smiled and told her, “You’re going to die soon. I’m the only person under heaven who can save you.” One of us is afflicted by a deadly poison, disguising herself as frail while plotting for ten years to overthrow the imperial throne. The other bears a blood debt, binds himself to a Villain System, and transforms from a frail scholar into a man-eating wolf. We are the most dangerous enemies and the most perfect allies. She gives me the power of life and death; I eliminate the threats within her ranks. She sees me as her sharpest blade, while I see her as a stepping stone to ruling the world. “Su Zhe, don’t fall in love with me. My husband could die a violent death at any moment.” “Rest assured, Princess. My blade never turns against one of our own.” Two mad souls join forces to stir up a storm and bathe the court in blood. Everyone thinks we’re using each other, never realizing that when two people who understand darkness best meet, they create the purest light!
