It's like that's the "point," and this is more average?"
"Your description is correct." Tang Ze nodded and said, "Because the damage caused by the dust explosion is exactly the same as this."
"Indeed, when I was doing my internship, I helped my teacher dissect victims of coal dust explosions. Their performance was very similar to the findings of this identification," said Ma Chengshi.
"Dust explosion? What is that?" Takagi asked puzzled.
This is not surprising. After all, the Internet is not particularly developed in this era. Common sense knowledge that is useless in later generations is still considered as niche professional knowledge.
As for why this piece of knowledge is so widely known in later generations, it is because many novels about time travel back to ancient times use this to show off their abilities when returning...
It's just like how time travelers memorize the formula for "black powder," but it's not as common...
"Take the coal dust explosion as an example."
Tang Ze said: "The working channel was filled with coal dust, which was ignited for some reason.
Coal, which is originally a solid substance, suddenly turns into gas due to combustion, and its volume expands a thousand times in an instant, and then an explosion occurs.
If there is a large amount of coal dust around the explosion site, it will be ignited continuously like firecrackers, causing a chain reaction of explosions."
"That's why, even though the explosion happened instantly and we only heard one explosion, there were actually multiple explosions that we couldn't see with our naked eyes."
Masashi nodded in agreement, "It is precisely because of this special explosion situation that the victim's body was hit multiple times in an instant."
"Are you saying there was a dust explosion in that kitchen?"
Gao Mu understood what they meant and said in disbelief, "But, that's the kitchen, right? There's no way there's something like coal powder there, right?"
"No, things like cakes can actually explode."
Tang Ze shook his head and said, "That's why it's called a dust explosion instead of a coal dust explosion.
Because coal dust explosion is just one type of dust explosion."
"Wow... I feel like I won't be able to look directly at snacks anymore." Takagi shrank his neck when he heard that.
"Don't worry, there's no chance that the cakes you bought will explode."
Masashi smiled and explained, "What Detective Karasawa said is that in the process of making pastries, if some powdered ingredients are not handled properly, there is a possibility of explosion."
"That makes it even scarier." Gao Mu said embarrassedly, "We have flour stored at home..."
"Don't be afraid. Dust explosions require harsh environments. Often, even if you deliberately conduct experiments, they won't succeed."
Tang Ze patted Gao Mu's shoulder and comforted him: "It is basically impossible to trigger it at home normally."
"Wait, if that's the case, then this case..."
After hearing what Tang Ze said, Gao Mu finally realized what was happening and said in a serious tone, "It's not an accident, but a deliberate murder?"
"Although we cannot be completely certain, at least in this case we cannot simply conclude that it was an accident and close the case."
Tang Ze stood up and looked at Masashi: "You've worked hard, you should have a good rest, the rest is our job."
"So what are we going to do now?" Gao Mu asked, "Are we going back to the crime scene to investigate further?"
"Let's go back today."
Tang Ze looked at Zuo Wan's watch and said, "It's already very late, and the crime scene is full of traces of the fire, so there is no way to find out a lot.
I'll give Saito Hiroshi a heads-up and ask him to send someone to go with us to the crime scene tomorrow to investigate further."
"Okay, I understand." Gao Mu nodded and said, "Then we will meet directly at the crime scene tomorrow."
"Um."
Tang Ze nodded, then took out his cell phone to contact Saito Hiroshi, and walked towards the underground parking lot.
When I got home, Ayako had already prepared dinner, and of course there was some complaints.
But after all, it was the other party's concern, so Tang Ze could only be lectured by the other party obediently.
But by the evening, Tang Ze found a way to get back at him, leaving Ayako without the energy to lecture him anymore.
The next morning, Tang Ze woke up early.
After getting up and washing up without waking Ayako, Tang Ze left a breakfast for Ayako and drove to the crime scene.
After arriving at the kitchen where the explosion occurred, Tang Ze discovered that in the empty room that had been emptied by the scientific research institute, Saito Hiroshi was busy doing something on the ground.
"What are you collecting?" Tang Ze looked at Saito Hiroshi curiously and asked, "Have you found anything?"
"Your judgment yesterday was correct."
Saito Hiroshi kept moving his hands while saying, "When I came here today, I felt some particles where I stepped. Considering the environment, I initially judged that it might be sugar.
If it was yesterday, the ground would be wet because water was used to put out the fire, so even if we came, we probably wouldn’t have found it.”
"It is because of the possibility after the fire is extinguished that the investigation was put on hold today."
Tang Ze smiled and said, "After all, I was at the scene yesterday. I know that the security personnel used fire hoses to put out the fire."
"Having a knowledgeable boss like you, I feel a lot more relaxed." Saito Hiroshi smiled and continued to collect the sugar that had solidified into pieces on the ground.
"Eh? Detective Tang Ze, are you all here already?"
