The general was wronged and the Shen family was in danger.
The world only knows that there is a legitimate daughter Shen Wanning in the General's Mansion who has been frail since childhood, but they don't know that there is a twin sister Shen Linyue hiding in the dark who wears a silver mask and holds two swords.
The younger sister lives in a deep house, using her frail body to plot people's minds, and works every step of the way; the elder sister hides in the dark, holding a sword as a secret guard to protect her family, and breaks the situation before moving forward.
One light and one dark, the two girls are of the same mind.
But when they peeled off the cocoon, they discovered that King Zhao was just an abandoned piece, and the real chess player was still hiding in the dark.
