More than three hundred members of the Shen family died tragically, and the culprit was actually Li Chengze, the current prince of the East Palace.
Shen Qingyi entered the palace as a slave incognito, and relied on the Shen family's unique blood poison acupuncture method to become the prince's exclusive medicine guide.
Every day he cut his wrists to draw blood to prolong his life, and hid a poisonous needle in his sleeve, just waiting for the time to take his life.
But the more they got along, the more doubts surfaced: he drank poisoned wine for her at the palace banquet, he blocked deadly arrows for her during the hunt, and the secret files in the cold palace concealed the entire truth of the empress dowager's coercion.
When an edict was issued to exterminate his family, he traded his own shame and the life of his biological mother for a glimmer of hope. He lived in the torment of atonement every day for ten years.
Connected by blood, sharing life and death, with a family full of blood feuds on one side, and a life-saving love on the other, Shen Qingyi holds poison in his hand and cannot do it after all.
