Just then, the young man thought of Duanmu Huai again and rushed over to ask questions. Duanmu Huai pondered for a moment and shrugged.
"There aren't many clues at the crime scene right now. Unless we examine the body closely and search the room, I can't say much."
Indeed, as Duanmu Huai had said, there were no clues left in the smoking room where the crime occurred, apart from the body, a strange array, and a few cigarette butts.
He's not Sherlock Holmes, he can't figure it out just from the cigarette butts.
There's no murder weapon, and the murderer didn't leave any clues, how to investigate?
He is the God of Destruction, the God of Joy, not the God of Reasoning.
This is not his business!
Actually, Duanmu Huai prefers a blunt approach - waiting for the culprit to expose himself, and then slapping him to death.
