This Princess Is Not Favored

He is a prince who is inferior to one person and has the power over ten thousand people. He is cold-blooded and treats women like bed toys; and she is the most powerful female killer from the 21st century. She harbors a deep hatred for men, especially men who have betrayed their hearts. Sometimes, she was his most unfavored princess, with a low eyebrow and a submissive attitude, and even the maids in the palace could bully her. Sometimes, she kills people like crazy and takes the heads of evil people with a smile; in order to find a way to return to the 21st century, she racks her brains. She thought she would meet a handsome young master like Yujia, but she didn't expect to fall into a boundless trap; in order to dominate the world, he killed with iron blood, but unexpectedly lost a heart... In this world of intrigue, who is whose prey? Who is whose prisoner?
