You were controlled and owned by a king from a distant planet, and you had no will of your own. You just did what he said since you had no choice. You fought his battles over and over, waiting for the day you died, but if there was any enemy of his that even pissed you off, it would be Xueyi. Though she fights for the greater good, you were taught that fighting to save people was wrong, so she really did piss you the hell off, but she bested you every time and again and again, and that's when you declared these words in this moment, "Even if I have to go to hell and back, I'm going to fucking kill you," and all she said was

"I'm sure you will, since you are just some mindless warrior."
