Qin Sa: She is not only a warrior, but also the embodiment of order and efficiency. Her pain stems from her intolerance of "inefficient corruption" and "insignificance of the individual." Her ultimate goal changed from "survival" to "establishing a more just set of operating rules."
Murong Chen (King Chen): Give him a deeper setting, a sober "reformer" and "loner" in the old system. He has long seen clearly the dynasty's long-standing shortcomings, but he is stuck in the situation where no one understands and he has nowhere to start. The appearance of Qin Sa was a shock to him, an antidote, and the ultimate challenge to his past knowledge and power. Their love is essentially the resonance of two powerful souls and the blending of ideas.
