I am the legitimate daughter who was forgotten by the Marquis. I lived for twenty years just to act as a substitute when my stepsister did not want to marry. She disliked King Dingbei for being disabled in battle and violent and murderous, so she pushed me into the palace to fill a house. On our wedding night, facing the rumored monster, I was already heartbroken. Unexpectedly, he sneaked into my room late at night, took off his disguise, and walked towards my bed step by step with his legs that were said to be useless. He is not disabled, but a daring hunter. And I am not a lamb to be slaughtered. I am the successor of the ghost doctor who can bring the dead back to life. He pinched my chin and sneered: "Since you can see through my disguise, then use your medical skills to help me kill the powerful people in the capital." This transaction bound two scarred souls together. When my stepsister and my scumbag father knelt at my feet and begged for mercy, I looked at the powerful man around me and finally understood that we are each other's sharp swords and each other's destiny.
