"Luminol!?"
Wang Chao suddenly exclaimed, looking at Xu Liang with a face full of surprise.
"Brother Liang, where did you get this from?"
What is Luminol?
It's a chemical reagent, certainly not considered rare.
It is an extremely important tool used by criminal investigators during homicide investigations.
What is its use?
It mainly has to do with blood.
When a person is killed, they bleed, and most murder cases involve bloodshed. The blood contains 'iron ions'.
The reagent in Luminol will turn blue upon contact with iron ions.
Therefore, at some crime scenes, if the perpetrator cleans up and the naked eye cannot see any blood spatter, Luminol can be used to reveal the spatter, further deducing the process of the crime.
"Found it in a forensic institution."
"They have plenty of this stuff there, so I bought some."
Xu Liang casually replied.
Wang Chao was quite impressed, occasionally glancing at Xu Liang's back.
