Deep inside the palace, the seventh prince Ji Zhao shows himself to others with a sick and broken body, his life hangs on a thread, and he is an abandoned piece on the chessboard of power. No one knows that under the weak body of "Qian Ji Yin" wrapped in strange poisons, there is a demonic wisdom that can penetrate people's hearts and a sharp edge that has been withheld for ten years. The imperial power is in conflict, the prince dies violently, brothers kill each other, foreign enemies are knocking on the door... The Empire State Building is about to collapse. When everyone is trapped in the quagmire of desire for power, only the despised "sick man" plays chess in the dark, using his own strength to make every move. He used Can Zhu's body as bait, used the world as his tactic, and fought every step of the way in the bloody storm. From being abandoned in the palace to becoming a mainstay, sick bones can also hide a world-shaking edge, but this supreme position is always hanging on a thin thread of life. This is a huge gamble with life as a bargaining chip.
