After Becoming the Emperor's Concubine, I Wanted to Kill the Emperor Every Night

The night before marrying Pei Lang. I was sent to the palace with a letter from my eldest sister and a bowl of poison from my eldest wife. I didn't become the head wife of the Pei family. She became a low-ranking concubine that everyone in the palace could step on. But I am different from those women who hold lamps every day and wait for the emperor's sincerity. What I want to wait for is the moment when his heart bursts and bleeds.
