In her previous life, she was a traitorous concubine who brought disaster to the country, but in this life she is transformed into a humble concubine in the prime minister's palace. She wanted to live a stable life, but she happened to be in the center of the iron-blooded tyrant's sight. He is a ruthless supreme emperor who kills people mercilessly and overturns his kingdom. But he treated her as a pet cat, letting her bite, indulging her to make noises, and even smilingly handed her a sharp knife that could destroy his empire - the empire was a cage, and the deep love was a rope; she wanted to turn the world upside down, but he was willing to surrender as a servant, using this prosperous world as bait to tame her. When the tyrant meets the little wild cat, the game of "taming" and "anti-taming" has just begun.
