The traces covering the existing footprints at the scene are not a large surface cover, but simply footprints.
Lu Chuan lay on the ground, continuously observing. Did the suspect really float in?
Impossible.
The suspect made such a mess of the house, it's impossible not to leave a trace.
Lu Chuan left no detail unchecked from the living room to the bedroom, carefully observing every tiny difference on the ground.
"Brother Hui, I have a frequency-tuned laser spectrum analyzer in my car. Can you get it for me?"
Lu Chuan seemed to have made some discoveries but was uncertain, as many details were still unclear in natural light.
"Sure, give me a moment."
Ten minutes later, Lu Chuan received the spectrum analyzer, pulled the curtains in the room, and the light instantly dimmed.
After turning on the spectrum analyzer, Lu Chuan adjusted the laser frequency, illuminating the ground, and suddenly a dense pattern of footprints appeared faintly.
