Things have developed to the point that they're actually quite simple now. The deaths of the Little Princess, the Queen, and Commander Kalon are not that important; they are just the first link in the plan, at most counting as three relatively important chess pieces.
The content of the entire plan is as follows: First, a murder occurs in the Royal Palace, and the identity of the deceased must be sensitive to draw away the Iron Hand, the powerful combat force beside the Old King.
Once the Iron Hand is drawn away, the assassination plan formally begins. The detailed steps are still unclear because the assassination failed before it even started.
This task isn't a detective case but rather a long-conceived royal assassination. Thinking this way, the whole matter becomes much clearer.
