Chapter 447 Killing Sunshine
With shadows, light can shine brighter.

Yu Fan's words made everyone feel curious and confused.

Yu Fan did not continue to play tricks, and said: "Actually, the chemical used by Xi Hongli is not phosgene, but chloroform!"

Guo Na seemed to understand, and said, "Chloroform?!"

Yu Fan: "That's right. Chloroform, generally refers to chloroform, a colorless and transparent liquid. It has a special smell. It tastes sweet. It has a high refractive index, is non-flammable, heavy, and volatile. The action of oxygen, gradually decomposes to generate highly toxic phosgene (carbonyl chloride) and hydrogen chloride. 0.6% to 1% ethanol can be added as a stabilizer. It can be used with ethanol, benzene, ether, petroleum ether, carbon tetrachloride, carbon disulfide Miscible with oils, 25ml is soluble in 1ml water at 200°C. Relative density is 1.4840. Freezing point is -63.5°C. Boiling point is 61-62°C. Refractive index is 1.4476. Low toxicity, half lethal dose (rat, oral) 1194mg/ kg. Anesthetic. Carcinogenic potential. On October 2017, 10, the list of carcinogens released by the International Agency for Research on Cancer of the World Health Organization was initially compiled for reference, and chloroform was included in the list of 27B carcinogens.”

Wen Xin: "Huh? Was Lei Radon killed by this 2B carcinogen?"

Yu Fan: "Exactly. And if I'm not wrong, Yixi was also stunned by chloroform."

Yixi: "So, it seems so. I mean, why did I feel a sweet smell in the room last night? I thought it was Yirui who knocked over Sprite and Coke for me again."

Yirui: "Grandpa, please remove the word 'again', when did I overturn Sprite and Coke?"

Yu Fan: "That's right. Chloroform has a strong anesthetic effect. That's how you unconsciously lost consciousness."

Cao Ben: "Then what happened to Lei Radon Wu there?"

Yu Fan: "It's very simple, all you need is this big cup." Yu Fan pointed to the transparent glass on the desk.

Yu Fan went on to say: "Xi Hongli just needs to go back to Lei Radon's room last night when the six gentlemen were drunk and drinking, put this transparent glass on the desk, and then pour high-purity chloroform into the glass. , Close the window. In this way, a timed chemical 'bomb' was made. Next, the sun was the killer who pressed the time switch. Lei Radon went back to the room in a daze without drinking until the early morning, and fell into bed. Just fell asleep without noticing anything weird. Gradually, the sun rose, and the sunlight just hit the glass on the desk. The chloroform and oxygen in the glass had a substitution reaction under the sunlight, and the oxygen Atom replaces one hydrogen and one chlorine to generate highly toxic phosgene (carbonyl chloride) and hydrogen chloride. As the reaction progresses, the density of phosgene in the room becomes larger and larger. In this way, Radon dies in the The real murderer, Xi Hongli, is climbing the mountain with us at this time, creating a perfect alibi."

Guo Na: "So that's the case."

Yu Fan: "Besides, if there is no accident, the time for Xi Hongli to take the chloroform was yesterday evening, before dinner. I went to look for Guo Na near the wolf pen, and accidentally found six wolves gathered on one side of the fence, heading towards the storage room. Look in the direction (Chapter 433 Foreshadowing). At that time, I was still a little curious, why the wolves were all focused on where to look. Now that I think about it, it should be that Xi Hongli happened to go to the collection room to get chloroform, so the wolf would stare in the direction of Xi Hongli. "

Guo Na asked: "He is really deliberate, but what is his motive?"

Yu Fan: "Yes, what is the motive? I just deduced his criminal trajectory. Next, I want to find his psychological trajectory!"

Yirui: "Psychological trajectory?"

Yu Fan: "Every person's every behavior must have its psychological logic behind it. These behaviors reveal people's own psychological state intentionally or unintentionally. Following these clues, perhaps we can touch the perpetrator's own psychological logic. mentality."

Cao Ben: "Uh, Lao Yu...can you see anything?"

Yu Fan: "The most obvious clues now are the two corpses. Observing the way the murderer treats the corpses, we can roughly figure out the murderer's mentality."

Yixi felt very suspicious and said: "As far as I know, Lao Xi doesn't know these six people at all. What kind of mentality would he have? Why would Lao Xi kill strangers? Lao Xi is not a pervert."

Yu Fan didn't answer, he stared at Lei Radon's body in a daze.

Wen Xin: "Old Yu, how about..."

"Hush..." Guo Na made a "whisper" gesture to Wen Xin.Guo Na knew that Yu Fan's brain at this time was like a chemical reactor. Yu Fan threw these unimaginable things into this reactor. No matter how complicated these chemical reactions were, he would eventually get a final chemical reaction from the reactor. Matter—that is, the ultimate answer.

"It's guilt." Yu Fan spoke.But his words were still elusive.

Chen Wanli: "Guilty? Xi Hongli expressed guilt for the deceased?"

Yu Fan: "No, on the contrary, the corpse is expressing guilt!"

Yixi was stunned, and asked: "Uh, Mr. Yu, can you explain in more detail? Why do I feel that I can't keep up with the rhythm?"

Yu Fan pointed to Lei Radon: "Look, Lei Radon put his hands together in front of his chest. This gesture is a gesture of repentance! Lu Krypton's body was stabbed to death with a stone knife, which in Greek mythology represents punishment and justice. Last night Yi Rui Mingming told Lu Krypton not to point at the moon, or his ears would be cut off. Lu Krypton refused to listen, and today Lu Krypton's ears were cut off. This is a symbol of retribution."

Yu Fan closed his eyes and entered the flow mode. He felt that he was in an empty and dark night sky, and there was a black shadow in front of him, and the black shadow was constantly squirming.Yu Fan knew that it was the devil hiding.To see the devil clearly, one must get close to the devil.Yu Fan cautiously floated towards the black shadow.Yu Fan's heart was beating very fast, he knew it was dangerous, but he wanted to see what the devil's purpose was!
Yu Fan seemed to see everything clearly, suddenly, the devil firmly grabbed Yu Fan's hand!It sucked Yu Fan like a black hole, no matter how hard Yu Fan tried, he couldn't get out.Yu Fan started to panic, damn it, this is my flow world, I am the master of my heart, why am I being controlled?Yu Fan felt that his body was being sucked towards the devil, and he couldn't help himself.

The devil even opened his mouth: "Hehe, in the black hole, even light can't escape. It's all involuntary. If you can't control your mind, how can you not control your body!"

what happened?The flow mode started to get out of control? !
"Brother Yu!" It was Guo Na who called Yu Fan.

Yu Fan suddenly opened his eyes, sweating profusely, what happened to him?
Yu Fan wiped his sweat.Guo Na asked with concern: "Brother Yu, what's wrong with you? Are you okay?"

Yu Fan: "Well, I'm fine, don't worry about me. I probably already know Xi Hongli's heart."

　There is no eternal hazy sky, as long as the sun of life rises from the heart - Chloroform
