"To be precise, it was a nitro compound fire," Saito Hiroshi corrected.
"That kind of thing is fine anyway." Gao Mu said speechlessly: "Rather, just hearing the name, I feel it's too outrageous."
"But the facts are before our eyes." Tang Ze shook his head and said, "This is scientific evidence, and science does not lie."
"I didn't find it when I first analyzed it."
Saito Hiromichi: “Later on, I felt that there was something wrong with the fire point and the distribution of the lamp oil, so I collected it again.
It's no wonder that professionals like the Fire Department and Samejima missed it. This is something that cannot be detected by experience and intuition.
After all, even our latest color gas spectrometer cannot guarantee a 100% detection unless we collect a sample with a certain amount of sodium carbonate."
"You've done a great job this time." Tang Ze patted Saito Hiroshi and said, "Well done."

Tang Ze nodded to indicate that he understood, then looked at Gao Mu and said, "Let's go. The first step is to find out where to buy the nitroglycerin used at the crime scene."
Of course, before that, he did not forget to inform Inspector Gongchang of this discovery.
After hearing this news, the other party's tone on the phone gradually became serious. After all, a professional arsonist is much more lethal than a small gangster.
Currently, arson is only carried out based on knowledge. If more dangerous bomb-like items are produced, it will be a huge hidden danger.
At the same time, Tang Ze also received news about Yumaga's criminal investigation.
As he had judged before, Yamamura Ying did not lie. Although he was excited when he saw arson, he did not do it.
The lamp oil was not bought by him, but was already in the deceased's family.
At the time of the incident, he was playing games in the arcade, as testified by the store clerk and the store surveillance.
