Yue Guang did not believe that Diao Deyi would do such a thing while in hiding, especially with the members of the Lin Family wearing night walking clothes.

"Just that... Lin Jie has placed too much trust in the source of the information."
"He even prepared night walking clothes in advance, as well as those masked cloths on the ground."
"He really planned to slaughter the entire Peony Workshop and those from the Foolish Underworld who came to investigate."
"The Peony Workshop can be understood, as it is indeed one of the territories of the Red Moon Demon; but what does he mean by killing the people from the Foolish Underworld?"
"Moreover, letting go of the most important members of the Mo Family in the Peony Workshop without any pursuit, yet ruthlessly exterminating those from the Foolish Underworld..."
"Something's not right... There must be something I've overlooked."
