She is the most powerful female mercenary in the 21st century. She has strong close combat skills and training talent, but she was framed by her fellow junior sister and fell off a cliff! Once traveled to another world of time and space... The Kyushu Continent that has never been recorded in history. As the newly married wife of King Yan of the Canglang Kingdom of the Kyushu Continent, her man was snatched away by an oiran on their wedding night! Not to mention, when I returned to my parents' home, I was accused of not having the face! If this revenge is not avenged... Well... She wants revenge, but someone prevents her from practicing magic and helps her from time to time. What does this mysterious man want? She could only tease him first, use him... And then wait for an opportunity to kick him away... "Thank you Demon Lord, the matter is done. Demon Lord, please come back!" Dongfang Wanxin saluted happily. "Oh? I am in a good mood today. I would like to invite Xin'er to accompany me for a drink and a chat..." Di Xingfeng sat firmly.
