My Lord, Don't Panic. Your Wife Is Just a Little Wild

[One true pairing + devoted to each other + equally powerful] Everyone said the current chancellor was blessed with good fortune: he had a beautiful daughter who dazzled the capital, and had secured her a fine match with the Ning Tai Marquis's household. No one knew that the chancellor's wife had given birth to twin daughters. One was hailed as a goddess of good fortune and kept in the capital, where she became a noblewoman, showered with favor. The other was branded a harbinger of disaster and cast out into the martial world, where she became a swordswoman who stood on her own.

She would make those who killed her sister pay! First on the list was Xiao Nanzhou, the Ning Tai Marquis: a man with eyes but no heart, who had spurned her sister's wholehearted love. The capital was in turmoil, with hidden currents churning beneath the surface. After Bai Qiao uncovered the truth, killed the villains, and brought the mastermind to justice, she turned to bid Xiao Nanzhou farewell. Xiao Nanzhou's eyes brimmed with bitter longing. “A Qiao, if I give you the entire martial world, will you stay by my side?” Bai Qiao: “This is bad, this is really bad. I've been ensnared by this menace!”
