"This is the lab report from the forensics office," Miao Ying said, passing her phone to Zhao Yu. She opened the bag and broke off a piece of chocolate for him. "Apart from traces of alcohol in the fire, there was also potassium permanganate and oxyacid compounds. These two compounds cannot be burnt directly, but under high temperatures, they produce a large amount of oxygen, which would have made the fire stronger! Forensics said that during the 1970s and 1980s, people used this method in crematoriums, but it was phased out as technology advanced."
"Holy sh*t, crematoriums?!" Zhao Yu was shocked. "It's obvious someone wanted to burn everything to ashes! No wonder the fire was so strong!"
