As an assassin, Lan Jiwan was exceptional. Her real identity—a young and attractive university student—provided excellent cover for her assignments, as few would deliberately guard against her.
Initially, Lan Jiwan genuinely believed she was carrying out "justice's punishment," for those she killed were indeed no good people, but she gradually sensed something amiss…
The Bitter Tea Sect prohibited its disciples from discussing the tasks they performed on regular days, and also forbade them from probing into each other's real-life identities. Thus, at first, Lan Jiwan was unaware of who her companions were or what they did regularly.
The Bitter Tea Sect even gave Lan Jiwan a mask that could conceal her Divine Sense, a privilege not extended to other companions, leaving them ignorant of her true face, while she knew what her companions looked like.
