Fantasy Villain: the First Female Protagonist with a Calculative Gambit

Dongfang Heng traveled through the world of fantasy novels and became the legitimate son of the Duke of Yan, one of the top powerful families. As soon as he traveled through the world, he got a marriage contract. The fiancée is also the first heroine in the novel who was forced to get married. She tried every possible means to escape from her clutches. She also kidnapped the protagonist's junior sister and imprisoned her? Dongfang Heng felt a little panicked in his heart. Did he offend the protagonist to death at the beginning? What, the original protagonist Su Yu is also reincarnated, he can take advantage of every opportunity to seize all kinds of heaven-defying opportunities, and then he wants to seek sworn revenge from him? ! This is a devastating start, and it's the end of the world! Wait, it seems that my identity and background are not bad, a bit awesome. Bite! The destiny villain system is activated! Hear the voices in your head. Dongfang Heng expressed that he was a little confused. He had a strong identity and background at the beginning + familiarity with the plot + God's perspective + system binding. This is a direct buff bonus stack. It's not as simple as trampling to death the protagonist, the so-called son of fate. The villain system robs the fate of various protagonists and achieves their own invincibility.
