The most inconspicuous disfigured concubine in the prime minister's palace was treated as an abandoned child and sent to the palace to pave the way for her sister-in-law. He thought he would definitely die, but in the thin line between life and death, with his extraordinary intelligence and ruthless desire to survive, he attracted the attention of the 9,000-year-old Pei Xuan, the ceremonial eunuch, who was shocked by the news. He regarded me as a perfect chess piece, accepted me as his disciple, lifted me up from the mud with his own hands, and taught me tactics, poisonous techniques, and scheming. I used "ugliness" as my armor and "conspiracy" as my blade to clear the obstacles for him and avenge myself in the dragnet he set. From an ugly girl who was bullied by others, to a wise concubine who doted on the harem, to a powerful female prime minister, I worked step by step to tear up with my own hands all those who despised me and trampled on me. And the relationship between me and my master has evolved from the initial use of each other to a dangerous and fatal forbidden love. When he wanted the country, I planned for him; when the country wanted his life, I overturned the country.
