"Zhao Yu, what are you doing?"
Miao Ying quickly ran to the balcony, only to find that Zhao Yu had already walked along the high courtyard wall in a tightrope-like posture as he walked out.
Zhao Yu's sudden action also attracted the attention of the other police officers, and they all turned their eyes to him.
However, Zhao Yu didn't care about the others "gazes. He walked a few steps along the courtyard wall, then took out his mobile phone and searched for the shoe prints that the technical team had found at the scene of the crime.
After that, he secretly activated a device called the footprint identifier. Zhao Yu had gotten this device a long time ago, and he had accumulated 15 of them.
As the name suggested, the function of the device was to identify and compare footprints, which was very useful for Zhao Yu's case-solving work.
