A Land Immortal from the Start, Bound to a Reborn Empress

After transmigrating into a fantasy world, Ning Yi becomes the Ninth Prince of the Great Yu Divine Dynasty. From the start, Emperor Wu arranges his marriage to a reborn female emperor. The dynasty is on the verge of collapse, with forces on all sides eyeing it hungrily, and its downfall seems imminent... Fortunately, Ning Yi activates the System! “You have successfully started cultivating while idle. You are automatically practicing the God-Slaying Sword Art and have gained supreme sword intent!” “Your comprehension is heaven-defying. You have successfully deduced the Dao of Immortal-Slaying and gained the Supreme Dao Body!” When immortals invade and destroy the dynasty, Ning Yi steps forward alone and sweeps across the thirteen provinces with a single strike, slaying every immortal! “So-called immortals are nothing but a single sword stroke away!” … My name is Liu Luoli. I’ve been reborn! In my previous life, I was the female emperor, but I was betrayed. In this life, I swear to reclaim everything that belongs to me, yet I never expected to marry the Ninth Prince, Ning Yi, from the start! How infuriating! How could I, the great female emperor, possibly get married! I refuse to accept this. Luckily, I awakened a comparison System. As long as I can defeat Ning Yi, I’ll earn rewards! I’m full of confidence. How could Ning Yi possibly compare with me, the future female emperor?! And yet... When I reached the Earthly Immortal Realm and was about to challenge Ning Yi, I saw him slay immortals alone with his sword and open the path to immortality. Liu Luoli was stunned! “Wait, is this really my husband? How can he be this strong!” “How infuriating! Which one of us is actually the one who was reborn?!” “Waaah, Husband, stop hitting me! I admit defeat, okay!”
