In the era of the Interstellar Empire, Lin Wanzhao, the legitimate daughter of the Hou Mansion, was treated as an abandoned son and married to the bitterly cold Beiming Star Territory, becoming the princess of Xiao Jingheng, King of Dingbei. Although she is frail, sick and bullied, she actually hides the inheritance of the Galaxy Medical Sage and is proficient in the ancient and modern techniques of treating poisons.
Beiming Star is surrounded by dangers: conspiracy in the imperial capital, invasion by foreign enemies, internal rebellion, and even mysterious forces spying on it. Lin Wanzhao used the poison-quenching silver needle as his blade and the doctor's kindness as his shield to deal with all forces. From an abandoned woman in Leng Yuan to the actual leader of Beiming, she and the iron-blooded prince Xiao Jingheng in a wheelchair went from testing each other to working together to uncover the huge conspiracy behind the "Shura Core" and "Marrow Powder" that affects the survival of the empire.
This is a counterattack path from chess piece to chess player, and it is a blade tempered between stars and frost, which will eventually cut through the silent night sky of the empire.
