With My Heart Sealed in Concrete, I Take Down the Girl Who Came Out of Nowhere

[Strong Female Lead × Super Satisfying × Mind-Bending] I was once a fallen princess of Yan, and a marriage contract gave me a foothold in Han. As the Third Prince's fiancée, I relied on that connection to hold back Yan's impending collapse. But then a goddess suddenly descended, stole my position, and tried to take my life. She conspired with the Third Prince to bring about the downfall of my country and the destruction of my family. The poisoned wine failed to kill me, but it closed my heart to love and showed me the ugliness of human nature. From then on, I stopped believing in romance. Hatred nurtured a poisonous seed, and a flower of revenge began to bloom. The bloodline secret of a foreign race, sealed away for years, awakened within me. I wielded alluring scents and bewitching arts to ensnare hearts. The once-elegant princess, Zhao Yuyan, now moved carefully at every turn, bent on killing her enemies with her own hands.
