Palace Killing! After Poisoning Me, She Became the Favorite Concubine of the Enemy Country

I was poisoned and silenced by my most trusted sister, "Jinlan", and was thrown out of the palace. Later, she became the favorite concubine of the enemy country, while I was picking up rags in the fishing village. No one knew that those peerless shell sculptures that noble people rushed to collect and that she couldn't put down were made by me, a "mute woman". She is using gold to buy the tomb I built for her with my own hands. Sister, we will "meet again" soon - on the scaffold.
