Open a blind box and don't know how to write an introduction.
Serious and honest little swordsman×Ming Sao Bai Qie Hei's little apprentice
The background of the knight is written randomly, just to satisfy the xp. I can't write ancient style, so I can only do my best.
Point of difference: The Little Swordsman is controlled by a sister. The role of the sister in the early stage is a bit too much, but it is only about family affection, so the sister will not have a name. It's pure love, but it gets a little twisted later on.
Purpose: World peace
