Honestly, this situation held no benefits to the Demonic Cult. They hid in the Imperial Palace to get rid of all the spies. If only the Guardians had handed over one spy (Elder Khum) as Chun Yeowun asked, he would’ve let the Guardians take credit, while he gets the information.

Apparently, she was not satisfied with that, Yeongwol used tricks that were obvious to everyone’s eyes.

“Ar-aren’t you scared of the aftereffects of such behaviour? If His Highness is told of such unruliness, the non-aggression treaty will be broken.”
