Rong Heng was born in a deep palace since childhood, and his life experience is shrouded in mystery. He is the royal family's secret pawn and silent witness. The empire is in turmoil, and the powerful ministers are undercurrents. A long-circulated edict pushes him into the whirlpool of power. Rong Heng was not moved by power, but due to an accident, he was involved in a secret case in the palace. The jade seal that was lost on the eve of the fall of the old dynasty reappeared, leading to a bloody past that had been sealed in dust. Loyalty and betrayal are intertwined, family affection and faith are torn apart. He discerns the truth among numerous doubts, not only to relieve the regrets of his father's generation, but also to break free from the shackles of fate. The palace walls are deep here, and everyone is in the game. With calmness and wisdom, Rong Heng traveled through the crisis-ridden court halls and deep palaces, vowing to exchange the truth for dawn and tell the world his true name that had been submerged by history.
