Once her soul penetrated, she became Yan Zhi, the most useless concubine in the Yan Dynasty.
The original owner was originally the legitimate daughter of the Hou family, but because of her biological mother, she was demoted and became a "fake daughter" that everyone can bully. Her aunt is hypocritical and her sister is vicious. The person she is forced to marry is the rumored "Nine Thousand Years Old" who is bloodthirsty and murderous - Regent Zhan Beixiao.
What? The man who held so much power that even the princes had to avoid him, was he a "living king of hell" who was about to die of illness?
As it happens, she is even harder to mess with.
In her previous life, she was a forensic doctor and toxicologist who walked on the edge of life and death. Yan Zhi was best at dealing with the dead and using poison to turn living people into dead people. On the first night of her marriage, facing the groom who wanted to establish his authority, she turned backhand with a silver needle that had been softened and said: "My lord, if you are weak, don't force love, it will kill you."
I thought this was a casual game waiting for men to die, divide their property and run away. But who would have known that Zhan Beixiao's "disease" was not that simple - it was a series of fatalities involving the remnants of the previous dynasty and the struggle for military power. What's even more troublesome is that this sinister and ruthless man actually wears a face of abstinence and stays in her room every day doing acupuncture. As he does so, a green light appears in his eyes...
