He saw a group of his colleagues inspecting an alleyway, so he went up to ask them.
"Has Liu Feihu passed by here?"
"His scent disappeared outside the alley, so logically, he must have entered this alleyway."
"Is it possible that he went over the rooftops?" Ma Lin pointed at a stone house nearby.
"I think it's more likely that he went through the alley. Look at that partition, I believe he might have removed his disguise there, then came back to eliminate any trace of his original scent."
Ma Lin examined the ground and said, "Can you identify his footprints?"
The lizard demon spoke, "He's dealt with the footprints as well. All the footprints on the ground are very blurred, which may be due to the rain, or it might be because someone deliberately used a spell."
Ma Lin went to the end of the alley to look around and concluded that tracking him this way would yield no results.
