I recommend the two novels,"The Princess 'Cultivation" and "Young Master Fu's Ways of Courting His Wife". They both meet the requirements of the title. The female lead of "Princess Consort's Cultivation" had an indifferent personality and was an upgraded cultivator. The female lead of "Young Master Fu's Ways of Courting His Wife" was an ace assassin and a top hacker. They were equally indifferent and cold. Their styles were different, but they were all very exciting. I hope you like my recommendation. Muah ~
