After taking revenge, Cao De had always been following Lih Qingshu's traces, secretly protecting her. The embroidered piece he had obtained was placed in the main hall where the Emperor met with court officials, framed and hung up.
This was another way he protected her.
He knew she had no interest in fame or profit, but he wanted every court official who came to see it, to know that she was recognized by the Emperor. He intended for the officials to tread carefully around her, to caution their subordinates and keep their eyes peeled, not to cause her any trouble.
Under Yuchi Zhao's administration, the world was rather just and orderly, yet his sister wandered from place to place, from the far north to the deep south, never settling down, elusive as a mist, with only Qian Chen as her guard. He always feared that some reckless souls would provoke her, beyond his reach to protect.
