Substitute: Forced to Be the Heir

On the day the city fell, I realized that the prince fighting alongside me was actually a girl. She fled to the South, and I entered the capital for her and became a pawn of the powerful. They used the lives of all the elders in my village to force me to perform this scene well. They don't know that in this body of mine, it's difficult to die even if I want to. They don't even know that my only sister in Jingbian City... Died in the massacre. It's time for me, the "chess piece", to hold the chess game in this capital city and the world.
