Lin Qi, the legitimate daughter of the Prime Minister's estate, was betrayed in her past life by the orphan Tan Susu and her fiancé Song Qi, resulting in her entire family being brutally executed at the vegetable market. Reborn back to the day of the adoption, she completely turns dark and plans every step meticulously. Appearing sickly and harmless, she is actually ruthless and cold-blooded, using her memories from the past life to hoard food supplies, destroy political rivals, and tear off the hypocritical masks of her enemies. She uses 'killing with kindness' on Song Qi and 'piercing the heart' on Tan Susu, turning the 'match made in heaven' of their past life into mad dogs tearing each other apart. With her great revenge fulfilled, she rejects the imperial throne and chooses to spend the rest of her life freely in her fiefdom—in this lifetime, she is only the master of herself.
