I was originally a modern young man obsessed with history, but I accidentally traveled to the Wu Dynasty and possessed the son of a useless general. Here, after the death of the first emperor, the princess disguised herself as a man and inherited the throne. However, the court was controlled by treacherous ministers, and the new emperor struggled. And I, relying on modern ideas and scientific and technological knowledge, am determined to counterattack and make my way in this strange and crisis-filled era. In the process, I met the empress who was as beautiful as a fairy and dressed as a man. She had unique charm and wisdom. From the initial mutual testing, we later joined hands to fight against the treacherous ministers, and wrote a legendary story in the Wu Dynasty that was both funny, suspenseful, and full of pure love.
