Ruthless and mercurial, Fu Wanqing is hardly the type of woman anyone expected to be heir to the Jianghu’s preeminent righteous cultivation sect. Yet she's famous for more than just her attitude: her raw power and beauty are renowned, rivaled only by those of demonic sect leader Yu Shengyan. As such, Fu Wanqing is determined to face her in battle; after all, she must prove herself not just worthy of her station, but superior beyond the rest! Unfortunately, the ice cold Yu Shengyan couldn’t be less interested in her challenge.

Yet when Fu Wanqing offers the rare medicine Yu Shengyan needs to cure one of her comrades, she relents. The catch? Yu Shengyan must agree to stay by Fu Wanqing’s side for three months. Fu Wanqing is certain that by the end of their deal, she’ll get her duel, but will her fascination with Yu Shengyan come to encompass more than just her sword?
