Travel to another world and become the husband of the empress.
What's going on with this ghost system of vying to be one's younger brother?
Also, I clearly don't understand martial arts in this world, but why am I still regarded as a martial arts master?
Empress: I'm so stupid. I really shouldn't have known that my husband was so strong until he led me out of thousands of troops with his sword alone!
Everyone: You two go to Versailles!
