It's ridiculous to say that I worked undercover in Zhenbei Palace for three whole years. The most skilled job I did was not killing people, but cleaning swords. He showed up at the prince's practice room on time every day, dipped deer skin in special turpentine oil, and rubbed the broken sword over and over again from top to bottom, from left to right.
What's so good about this sword? It's not a magic weapon, it doesn't even have a decent scabbard. But Xiao Cijing, that dog prince, is very precious. Every time I finish practicing the sword, I have to clean it with my own hands, and no one else is allowed to touch it.
I was mechanically repeating the action of cleaning the sword when my fingertips suddenly touched an uneven spot.
