Deep in the palace of the new emperor Xiao Yan, an old sword without a blade hangs. Everyone said that the emperor was looking for a sharp weapon that could stabilize mountains and rivers. Only he himself knows that he is looking for a "dead" person. Seven years ago, the medical girl Shen Awu took the blame for him, and her body was not found. Seven years later, the top masterpiece "Princess Princess" presented by the enemy country sneaked into the palace. Her eyes were filled with unfamiliar coldness and calculation. He trapped her by his side, testing her day and night, watching her perfectly play another identity, but always inadvertently revealing little habits that only belonged to A Wu. He threw a cup as a sign at the palace banquet, surrounded the palace with iron armor, and tore off her mask with his own hands in front of all the civil and military officials. His voice was trembling: "This time, my kingdom is given to you first. Are you willing to... Save me again?" She looked at his red eyes and finally shed tears after seven years. The poisonous hairpin in her hand was pressed against his throat: "But the first lesson I have to learn when I come back is to learn not to trust you."
