This sounds like the premise of an intense, action-packed story full of mystery and intrigue. The relationship between Dafeng and Li Huamei seems complex, with both of them being drawn into larger political and personal conflicts. The twist that Li Huamei’s senior sister is actually the Queen, and that the Queen is trying to kill her, adds a layer of betrayal and tension to the plot.
Dafeng’s connection to all of this being the key to solving the mysteries suggests a deep backstory for him, one that might reveal secrets about his identity, purpose, or skills. The idea of both characters navigating through betrayals, conspiracies, and threats in both the courts and the rivers and lakes makes the stakes incredibly high.
