Chapter 446 The Evil of Phosgene
Those who swim in sin will surely sink in sorrow.

Yu Fan, Guo Na, Cao Ben, Wen Xin, Chen Wanli, Yi Rui, and Yi Xi walked out of the collection showroom and ran towards the ground wing where the six gentlemen were.

I don't know what Xi Hongli wants to do, but everyone has an extremely ominous premonition in their hearts.This is a long-planned conspiracy.

"Ah! Someone!" Guo Na exclaimed.

I saw a figure lying motionless by the roadside of the wolf pen in front of me.

The seven people stopped, and Yu Fan slowed down, moving towards the figure carefully.

hiss!This person is... Lu Krypton.

Yu Fan leaned over to observe, Lu Krypton had no signs of life.

I saw Lu Krypton lying in the middle of the road, with several bloodstains on his face, his eyes closed, his hands drooping naturally, a knife made of stone stuck in his chest, and his clothes were stained redder by the blood oozing from his chest.Lu Krypton's right ear was cut off by a sharp instrument...the death was tragic.

Yu Fan stood up, shook his head and said to everyone, "He is dead."

Yixi: "What's going on, what's going on? Did Xi Hongli do it? Why did he do this?"

Yu Fan: "..."

"Ah! Look, is there another one missing?" Wen Xin pointed to the wolf in the wolf pen.

Everyone looked at the wolf circle. There were originally six wolves, but now there are only four left!The remaining four wolves bared their fangs, looked fiercely at the humans outside, and seemed to say, "I've had enough of your humiliation. If there is no fence, I will tear you to pieces now!"

The situation is getting weirder and weirder!

Yu Fan also frowned, what... does this mean?
Guo Na: "Strange, why was Lu Krypton's ear cut off?"

Yirui: "Ah! Could it be the legend that came true?"

Cao Ben: "And what legend?"

Yirui: "That's right, if you point at the moon, your ears will be cut off! Last night when we had barbecue, he pointed at the moon. I told him, but he didn't listen. (Chapter 434 Foreshadowing)"

Chen Wanli: "I'll go, your villa is too evil!"

Yu Fan silently analyzed and reasoned, why did Lu Krypton have his ears cut off?Why choose stone knives?Why did another wolf disappear?All this looks like, how come there is a sense of ritual?

Yu Fan said to everyone: "Forget about here, the most urgent thing is, we have to rush to the ground wing, it seems that the killing has already started! Everyone, don't fall behind!"

Yu Fan led everyone to continue to the ground wing, walked through the garden, walked through two corners, and the ground wing was in front of us, but...

The door of the ground wing room has been opened...

Yu Fan and Guo Na stood carefully at the door, lowered their weight, and observed the movement inside.The ground wing was very quiet, there was no sound at all.

Yu Fan yelled at the room at the door: "Xi Hongli, we have already found you, don't get trapped further! Put your head in your hands and come out!"

Yi Rui also shouted: "Grandpa Xi, come out and stop messing around!"

Yixi: "Old Xi, come out and tell them what's going on? Is it a misunderstanding?"

There was still no movement in the house.

Yu Fan made a countdown gesture to everyone, three, two, one, go!Everyone rushed into the house together.The house is empty!
Neither Xi Hongli nor the Sixth Gentleman Duxing were in the room.Only Lei Radon's dead body was still lying quietly in the room.

Yu Fan gritted his teeth and said to himself: "Damn it, it's still a step too late!"

Cao Ben asked Yu Fan: "Old Yu, what should we do now? Let Xi Hongli run away."

Yu Fan didn't answer, and walked directly into Lei Radon's room, looked at Lei Radon again, then picked up the empty cup on the desk for a closer look, bowed his head and said to himself: "It's true, it's true!"

Guo Na: "Brother Yu, did you find anything?"

Yu Fan: "Track!"

Guo Na: "What trajectory?"

Yu Fan: "Xi Hongli's criminal trajectory! I know how he did it. I know how he killed Lei Radon from afar."

Cao Ben: "Old Yu said quickly, what's going on?"

Yu Fan: "It's phosgene! Phosgene, also known as carbonyl chloride, is highly toxic, non-flammable, highly reactive, and highly corrosive when exposed to water. It is slightly soluble in water, soluble in aromatic hydrocarbons, benzene, and carbon tetrachloride. , Chloroform, acetic acid and other organic solvents. Generally, it is made from a mixture of carbon monoxide and chlorine through activated carbon. Phosgene is a colorless gas at normal temperature, with a smell of rotten grass. It is a yellow-green liquid at low temperature. It is chemically unstable and quickly meets water It is hydrolyzed to produce hydrogen chloride. As soon as I entered this room, I smelled a smell of rotten grass, which is definitely phosgene.”

Wen Xin quickly covered his nose: "Damn it! It's poisonous here!"

Yu Fan smiled calmly: "The semi-lethal dose LD50 of phosgene inhalation poisoning is 3200 mg/kg, and the semi-incapacitating dose is 1600 mg·min/m3. As soon as we came in in the morning, we opened the window for convection, and the current concentration is already negligible. .”

Guo Na: "When I came in early in the morning, I also smelled a lot of rotten grass. I thought it was the smell of nature."

Chen Wanli: "If it is said that Lei Radon died of this highly toxic phosgene, then, did Xi Hongli inject phosgene into the room before we climbed the mountain with us in the morning, and then slowly poison Lei Radon to death? It’s not that easy to get so much phosgene into the room, right? Besides, there are so many rooms in the ground wing, so it’s easy for other people to find out. Besides, the time in the morning is too short, and he’s going to inject poison and do it for us. Breakfast, and then take us to climb the mountain, there is no time to commit crimes!"

Yu Fan pushed his glasses lightly, and said, "Who said Xi Hongli went to poison in the morning? In fact, all his work was done last night."

Cao Ben: "Last night? In other words, last night, Xi Hongli injected phosgene into the room in advance? And then waited for Lei Radon to go back to the room after drinking, and then died of poisoning?"

Guo Na: "Uh...Brother Yu, I think this explanation is a bit far-fetched. Such a high concentration of phosgene has a strong smell and makes people very uncomfortable. Ray Radon will definitely notice it and won't enter the house. And even if Lei Radon was drunk and didn't pay attention to the smell, the phosgene had already dissipated from midnight to early morning, and it couldn't reach the lethal concentration, how could Lei Radon be poisoned to death?"

Yu Fan smiled slightly: "Na Na, you are very right. If Xi Hongli only relies on phosgene, the success rate is too low and it is too troublesome."

Wen Xin: "What do you mean? Sometimes it's phosgene, and sometimes it's not."

Yu Fan walked to the desk in front of the window, picked up the empty cup again, smiled confidently, and said, "Lei Radon did indeed die from phosgene, but the phosgene was not released by Xi Hongli."

Yu Fan put the cup back on the table, looked at the sun outside the window, and said deeply: "For most people, the moment the sun rises symbolizes hope. For some people, the moment the sun rises symbolizes hope. , a symbol of death!"
