Phoenix and Nine Heavens: the Night Emperor's Contracted Poisonous Concubine

Feng Qingyin, the chief poison doctor in the last days, once traveled through time and became the concubine who was bullied by the Duke of Jingguo and was selected to be the sick king Xuanyuan Ye Chongxi. On the wedding night, both of them took off their disguises - she locked her throat with a silver needle, and he resisted internally. After a confrontation, each party saw through the hidden edge of the other, and then settled on a contractual marriage of "she detoxifies, he protects", and started a "cooperative" life of competing in each other's acting skills in the palace.
