Chapter 156 Who is it?
Chen frame Yang remembered what Guo Na said yesterday.

Guo Na said yesterday that solid Geshi’s (sodium hydroxide) will dissolve into the moisture of the air to form a liquid poison when placed in the air. If Geshi’s is placed in such a humid environment, it is still a closed space. It takes one night, and everyone in the room will be poisoned to death.

And now the lid of the barrel of geese in the room has been completely opened!
Chen Xingyang hurriedly held his breath and went over to cover the lid of Geshi's bucket.Then rushed to the door of the room and took a big breath.

Yu Fan was still standing in the room blankly, Chen Xingyang turned his head and pulled Yu Fan, and shouted: "Old Yu, be careful of poisoning! Come out quickly."

Yu Fan came back to his senses, shrugged his shoulders, smiled, and said, "Oh, there's no serious problem, no one can die."

Chen Xingyang still yelled: "I'm going, liquid poison! Boss, are you still scared by what happened last night?"

Yu Fan smiled lightly and said, "In fact, solid sodium hydroxide will not produce liquid poison when exposed to the air, let alone cause death. Sodium hydroxide will absorb water vapor in the air and turn into sodium hydroxide solution, and then absorb carbon dioxide in the air, a chemical reaction occurs to produce sodium carbonate and water. The final air environment is a safe environment, there are no free hydroxide ions, and there will be no such thing as strong alkaline air.”

Guo Na wondered: "Huh? I remember watching Conan when I was a child. There was an episode about killing people with solid sodium hydroxide in the air?"

Yu Fan smiled and said to Guo Na: "Conan lied to you."

Chen Xingyang just wiped the sweat off his head, exhaled and said, "Hey, it's a false alarm, a false alarm."

At this time, Yu Fan said seriously: "This is not a false alarm, we didn't open this bucket, right?"

Guo Na and Chen Frameyang shook their heads.

Yu Fan: "Yesterday afternoon, I had the impression that we put the lid on the bucket well, and the lid of the bucket was also well before going to bed. Why did the lid open in the morning?"

Guo Na recalled: "Yeah, who is it and when did it open? Last night we closed the door to sleep, and no one would come in. Wait! We got up in the middle of the night and went out to track it down. Didn't close the door, could it be That's when this guy slipped into the house and opened the lid?"

Yu Fan bowed his head in thought and did not speak.

Chen Xingyang cursed and said: "Which turtle did this good thing? It's deliberate. It's trying to poison us to death?"

Yu Fan's bad premonition seemed to have become a reality.But after experiencing some previous things, Yu Fan's heart has already become strong.

Yu Fan: "When we cleaned up the room yesterday, the villagers came to the house one after another to pick up their things. Someone must have heard us talking about the brother's turning into liquid poison. Invisibly, we seemed to 'teach' him One move to kill us, so..."

Chen Xiangyang seemed to understand something, and said: "So, the suspect is among the villagers? Let me go, why is the matter getting more and more complicated? Besides the short group, there are also villagers who want to kill us?"

Yu Fan looked blankly, and said: "I don't know, maybe. Let's go to the people in the village to find out." Yu Fan and the others discussed going to a few households to find out the situation first, and then go to the village head together .

The three of them packed up their things and started the visit according to the original plan.

Yu Fan stood on the stone steps and looked at the villagers coming and going in the village. No matter how you looked at them, they were all simple fellows.Who would deliberately set up such a situation to lure Yu Fan and the others out, and then enter the house and open the lid of the barrel?What is their purpose?How much hatred is there to kill, to kill and silence?What did Yu Fan and the others know or touch by accident, which caused big trouble?

An unknown amateur writer Yu Yiji once said: "If there is no clue in front of you, then go back to the starting point of the problem."

Yu Fan returned to the entrance of Ziwu Village and re-entered the border of Ziwu Village.Everything today is exactly the same as yesterday, everyone is doing their own things, but today no one looks at Yu Fan with strange eyes anymore.

At the door of the farmhouse on the side of the road, the young man was still playing with his mobile phone with his head down at the door, and next to him was the old man from yesterday, playing with his leaf tobacco.

Same as yesterday, Yu Fan walked over and chatted with the young man: "Young man, don't you work?"

While rubbing the screen hard, the young man said impatiently: "Don't you young man, who the hell is this young man? Don't I deserve a name?" Yu Fan saw that the young man's game today was different from yesterday's. It's the pesticide of the dead, and today I'm playing Clash of Clans.

Yu Fan said apologetically, "Ah, I'm sorry, may I ask..."

"My name is Shen Wei. I am the only respected Wei." The young man interrupted Yu Fan.

After finishing speaking, in Shen Wei's game, he successfully destroyed the opponent's main camp.

Shen Wei: "Finally, I succeeded in crossing the tribulation. It was too difficult to beat this level." Shen Wei was still addicted to the joy of the game.

Just as Yu Fan was about to ask questions, Shen Wei spoke up first: "I think you and I are destined, every time you come to me these two days, I can successfully overcome the catastrophe by playing games, you are my lucky star Ah. How long will you stay with us? Don’t worry, I still have Football Manager and Pippi Mahjong, and I need you to add a BUFF to help me survive. Brother, do you play games?”

What a young Internet addict, Yu Fan smiled and said: "I used to be obsessed with games, I played all kinds of games, and I played them well, but because of some reasons, I stopped playing."

Shen Wei: "What's the point of living without playing games?" Then he turned on Pippi Mahjong again.

Yu Fan continued the question just now: "Are you young and don't work?"

Shen Weiyi said while playing the game: "I used to run machine tools in a state-owned enterprise, but I resigned. It's the Chinese New Year, so I won't go out."

Yu Fan asked again: "Are you a native?"

Shen Wei raised his head to look at Yu Fan, and said, "Isn't this nonsense? If you're not a local, who would be in this poor place? Look at how many young people there are in this village besides me?"

Yu Fan thought about it, and said, "That's right, who would live in a place called a ghost village for nothing, how scary."

Shen Wei shook his head: "It's not because it's scary, but because the signal here is too bad, and the game lags too much."

In Yu Fan's heart, a group of mud horses ran past, okay, you won.

At this time, Yu Fan had an idea and asked Shen Wei: "Since you don't have a job now, are you interested in taking a part-time job?"

Shen Wei raised his head and said with a little interest, "What part-time job?"

Yu Fan said solemnly, "Guide."

　ah?It turns out that solid sodium hydroxide will not become liquid and poisonous when it is released into the air? — Conan
