I'm an Immortal Emperor, Yet the Female Emperor Captured Me from the Start

[Female Emperor + Swordsmanship + System + Decisive and Ruthless + Flirtation] Ning Xuan, the Azure Cloud Immortal Emperor, was ambushed. Reborn with only a sliver of his divine consciousness, he hoped to return to the Immortal Realm and strike back, but found his entire body shackled and his cultivation destroyed. Then he awakened the Dotage System. With one sword, I, Ning Xuan, can destroy a city; with three, slay a Demon Venerable; with ten, trample the world! I, Ning Xuan, am the greatest husband in the world at upholding the rules of marriage! Ahem... Ling'er... Ning'er... Shuangshuang... There's no carriage here, so hold still and let this Immortal Emperor fleece you a little. (●'◡'●)
