The Enemy Is at the Gates, and the Empress Finally Remembers I'm in Prison

But treacherous villains framed me, accusing me of building up my own forces and plotting rebellion. I was thrown into the imperial prison and ultimately died behind bars.

At last, she remembered me, still locked away in the imperial prison.
