Single female protagonist + decisive killing + cool writing + tsundere sword spirit
After three years of humiliation, I cleared my name with one sword.
Facing the enemy, I kill decisively.
I am Xu Shuangxing!
I have Tsundere Sword Spirit.
I have heaven-defying skills.
I am accompanied by Xuanyuan Xiaoxi, the most beautiful woman who protects my husband.
I, Xu Shuangxing, have all these.
Fellow Taoist? Do you have it?
No,
Just give in.
I, Xu Shuangxing, am invincible in the entire universe.
