Besides, even if those four people were silenced, Ling Hua had already made clear moves in front of the Emperor. Even if she returned without success due to the dead soldiers being silenced, as long as the Crown Prince made a move, bribed Jingzhao Prefecture, and silenced those four people, the Emperor, because of her hint, would pay attention to the Crown Prince and every action of the Wen Family, knowing it was the Wen Family's doing.

The Emperor would hold a deep-seated grudge against the Wen Family and keep a harsh score on them.
