"We found a total of three separate ignition points at the scene, and accelerant components were detected at each one."
Mr Li slowly put down the teacup in his hand, his expression suddenly turning solemn, his gaze sharp as a torch: "What accelerant was it?"
Jiang An answered immediately: "Rapeseed oil."
"Rapeseed oil?"
Mr Li was slightly taken aback, his fingers unconsciously tapping on the tabletop.
"Gasoline and alcohol are both under very strict control now, especially gasoline; it's extremely hard to obtain for non-vehicle use, and purchasing it requires real-name registration."
"Alcohol, as a flammable substance, is also a highly regulated material… The killer choosing rapeseed oil is actually quite logical."
He followed up at once, his tone carrying a professional caution: "Can the cooking oil at home really act as an accelerant?"
"Absolutely,"
