"So-called immortals can be slain with a single sword strike!" … My name is Liu Luoli, and I have been reborn! In her past life, she was an empress, but she was betrayed. In this life, she vowed to take back everything that belonged to her, but she never expected that she would marry the Ninth Prince Ning Yi right from the start! How dare she!

As long as she could defeat Ning Yi, she could get a reward! She was brimming with confidence. What did Ning Yi have to compare with her, the future empress?! However…… When she broke through to the Land Immortal Realm and was preparing to challenge Ning Yi, she saw Ning Yi alone with his sword, slaying immortals and opening the path to immortality. Liu Luoli was stunned! "No, this is my husband? How can he be so strong!" "Damn it! Who was the one who was reborn?!" "Waaaaah, husband, please stop hitting me! I give up, okay?!"
