Chapter 379 Celluloid Smoke Bomb
Lied to you in front of all of you, that's the magic of magic.

Without warning, a murder occurred in the No. [-] box of the soft sleeper car.

After the hustle and bustle, there was calm, and the white smoke in the house gradually dissipated. Yu Fan and Chen Xingyang were discussing the case in the private room...

Chen Xingyang: "Lai Bushuang was fine yesterday, why did he die suddenly? By the way, Lao Yu, what happened to the bomb just now? You said it was a smoke bomb?"

Yu Fan nodded and said, "Well, just now I smelled a special smell of bitter almonds, which is exactly hydrogen cyanide."

Chen Xingyang: "Hydrogen cyanide? I seem to know this, it is..."

"Hydrogen cyanide is a liquid in the standard state. Hydrogen cyanide is easy to disperse evenly in the air and is flammable in the air. When the content of hydrogen cyanide in the air reaches 5.6% to 12.8%, it is explosive. Hydrogen cyanide is a violent Toxic. The clinical manifestations of acute hydrogen cyanide poisoning are obvious bitter almond smell in the patient’s exhaled breath. Mild poisoning mainly manifests as chest tightness, palpitations, rapid heart rate, headache, nausea, vomiting, and blurred vision. Severe poisoning mainly manifests In a state of deep coma, with shallow and fast breathing, paroxysmal convulsions, and even tonic convulsions. In World War II, Germany often used hydrogen cyanide as the murder gas in gas chambers." Yu Fan used his representative scientific style The speech interrupted Chen Frameyang.

Chen Xingyang said weakly: "Uh... well, you should explain in more detail. Then this smoke is hydrogen cyanide?"

Yu Fan shook his head. He opened the kettle, took out the ball of paper soaked in it just now, spread it on the table, and said, "Look, what is this?"

Chen Xingyang took a closer look, and it turned out to be some ping pong ball fragments.

Chen Xingyang: "So that's how it was. I was shocked. I thought it was a bomb. So, the white smoke from burning table tennis balls, that is, hydrogen cyanide, killed me?"

Yu Fan: "Of course not. The composition of table tennis is celluloid. The combustion of celluloid is a complicated process, and it will produce toxic gases such as nitrogen oxides. It will automatically decompose without oxygen to produce carbon monoxide, methane, hydrogen, nitrogen monoxide, and carbon dioxide. Inflammable, explosive and highly toxic gases such as nitrogen and hydrogen cyanide. The lethal dose of poisonous gas is 1mg/kg (body weight). We have also seen that this is not a closed room, and the concentration of poisonous gas cannot reach the lethal dose at all, otherwise we I wouldn’t stand and talk in the box. Even if the concentration was high at that time, such a high concentration would inevitably cause the gas to leak out, and it’s impossible for us in the entire compartment not to smell this strange smell. And to reach that concentration , the amount of white smoke is far more than that."

Chen Xingyang got up, approached Lai Bushuang's body, observed by himself, and muttered to himself: "Then how did this Lai Bushuang die? Also, who is going to release this smoke bomb? To deceive people's eyes and ears?"

Yu Fan said to Chen Xingyang: "Old Chen, there are still many doubts here. We can't solve the problem alone. We need the help of the ground police and forensic doctors. Please help me call the train conductor and conductor outside. There is the young man Moli who discovered the situation here for the first time just now. We have to consult them about some things."

Chen Xingyang opened the door, unexpectedly the person he was looking for was already waiting at the door.Guo Na, Zuo Zircon, Yi Xin, Mo Li, and a steady-looking middle-aged man. He is wearing a railway uniform, with a star and a stripe on his epaulets, and a red line on his cap. Judging from this, he should be the train conductor. up.

Chen Xingyang asked: "Where is the flight attendant in this carriage?"

Yixin: "Oh, he went down with the female thief and cooperated with the public security department. Now that I'm on duty, I'm the official steward of this carriage. In fact, the original plan was that I would replace him today. He's going to get off the train." Car back home."

Chen frame Yang thought, when the female thief got off the car, Lai Bushuang was still alive, so the flight attendant should not be the murderer.

The train conductor said: "Hello, Comrade Police, I am the conductor of this train. What is the situation now?"

Chen Xingyang: "There was a murder case here, and the other specific circumstances are not clear yet. So I would like to invite everyone to come over and ask you some information."

"Where is the next stop on the train?" Yu Fan came out of the box.

Train conductor: "The next stop? The next stop is XA station. This is a large part of the journey through the cave, so there are no stops. Now this train is a bit late, and it is moving at full speed. It will be around noon." It's XA."

Yu Fan rested his chin on his hand, bowed his head in thought.

Chen Xingyang asked Mo Li next to him: "Little brother, you were the first to find out, right? How did you find out?"

Mo Li rubbed his nose and said, "After I woke up in the morning, I stood in the aisle, but after a while, I smelled a strange smell. I sniffed it carefully and found that it seemed to be the room No. [-]." It came out, I thought the person inside accidentally set the plastic on fire, so I knocked on the door to ask what was going on inside. After knocking for a long time, there was no response, so I directly pulled the door with my hand, the door was unlocked, and I opened it directly. Yes. Then, I saw the man inside lying on the bed with wide-eyed eyes. I called him a few times, but there was no response. When I touched his face, it was cold! I knew something was wrong, and I was so scared that I quickly retreated. Come out, at the same time, I also found that there was smoke slowly coming out of a package on the table, I thought it was a bomb! You will see what happened next."

Yu Fan still bowed his head in thought.

Chen Xingyang sighed endlessly: "Damn it, how did you die when you are alone?"

Yu Fan slowly raised his head: "I think, I probably know the cause of his death."
