Chen Jianyang remembered what Guo Na said yesterday.

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

And now the lid of the bucket of gossiers in the room has been completely opened!

Chen Huanyang hurriedly held his breath and went over to close the lid of the gorg's bucket. Then rushed to the door of the room and took a big breath.

Yu Fan was still standing in the room in a daze, Chen Jieyang turned around and pulled Yu Fan, and called: "Old Yu, be careful of poisoning!" Come out quickly. ”

Yu Fan came back to his senses, shrugged his shoulders, smiled, and said, "Oh, it's no big deal, you can't die." ”

Chen Jieyang still shouted and said, "I'll go, 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 air, let alone make people die. Sodium hydroxide absorbs water vapor from the air to form a sodium hydroxide solution, which then absorbs carbon dioxide from the air and undergoes a chemical reaction to produce sodium carbonate and water. The final air environment is a safe environment, there are no free hydroxide ions, and there is no strong alkaline air. ”

Guo Na was puzzled: "Huh? I remember watching Conan when I was a kid, and there was an episode about using solid sodium hydroxide to put it in the air to kill people? ”

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

Chen Jiaoyang wiped the sweat on his head, exhaled and said, "Hey, a false alarm, a false alarm." ”

At this time, Yu Fan said solemnly: "This is not a false alarm, this bucket was not opened by us, right?" ”

Guo Na and Chen Frameyang shook their heads.

Yu Fan: "Yesterday afternoon, I still had the impression that we should cover the lid of this bucket well, and the lid of this bucket should also be well before going to sleep." Why is the lid open in the morning? ”

Guo Na recalled: "Yes, who is it and when did it open? We went to bed last night with the door closed, and no one will come in. Wait a minute! We got up in the middle of the night and went out to follow the door, didn't close the door, could it be that this person slipped into the house and opened the lid at that time? ”

Yu Fan lowered his head and pondered without speaking.

Chen Jiaoyang scolded and said: "Which turtle grandson did a good thing, he was scheming, this is trying to poison us?" ”

Yu Fan's bad premonition seems to have come true. But after experiencing some things before, Yu Fan's heart has already become strong.

Yu Fan: "Yesterday, when we were cleaning up the room, the villagers came to the house one after another to pick up their things, and someone must have heard us talking about the topic of turning into liquid poison. Invisibly we seem to have 'taught' him a trick to kill us, so ......"

Chen Jieyang seemed to understand something, and said, "So, the suspect is among the villagers?" I go, how is it getting more and more complicated? In addition to the short group, there are also villagers who want to kill us? ”

Yu Fan's eyes were empty and he said, "I don't know, maybe." Let's go find someone in the village and ask around. Yu Fan and the others discussed going to a few households to understand the situation first, and then they went to find the village chief together.

The three of them packed up their things and started the visit as originally planned.

Yu Fan stood on the stone steps, looking at the villagers going back and forth in the village, no matter how you look at it, they are all simple fellows. Who would deliberately set up such a situation to lure them out and then enter the house and open the lid of the barrel? What exactly is their purpose? How big is the hatred that wants to kill people? What did they know or touch by accident and get into 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 boundary 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.

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 still yesterday's uncle, fiddling with his leaf cigarettes.

Yu Fan, like yesterday, walked over and talked to the young man: "Young man, don't you work?" ”

The young man tried to rub the screen and said impatiently: "Don't be a young man, who is the young man?" Am I not worthy of a name? Yu Fan watched the young man play a game today that was different from yesterday, yesterday he played the dead pesticide, and today he played the clash of clans.

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

"My name is Shen Wei. The only one who is the only one. The guy interrupted Yu Fan.

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

Shen Wei: "Finally the tribulation was successful, and it was too difficult to knock over this level." Shen Wei is still indulging in the joy of the game.

As soon as Yu Fan wanted to ask, Shen Wei spoke first: "I think I have a good relationship with you, every time you come to me in the past two days, I can successfully play the game, you are simply my lucky star." How long will you stay with us? Don't be in a hurry, I still have the football manager and Pippi Mahjong who need you to add a buff to help me get through the disaster. Brother, do you play games? ”

What an Internet addicted teenager, Yu Fan smiled and said: "I used to be obsessed with games, I played all kinds of games, and I played them well, but then I stopped playing them for some reasons." ”

Shen Wei: "What's the point of living without playing games?" As he spoke, he opened the Phi Phi mahjong again.

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

Shen Weiwei said while playing the game: "I used to drive a machine tool in a state-owned enterprise, resigned, and it was about to be the New Year, so I didn't go out." ”

Yu Fan asked again: "Are you a native of the country?" ”

Shen Wei raised his head and glanced at Yu Fan, and said, "Isn't this nonsense?" If you're not a local, who's going to be in this place? Do you see how many young people in this village besides me? ”

Yu Fan thought about it and said, "It's okay, who has nothing to do to live in a place known as a ghost village, how scary." ”

Shen Wei shook his head: "It's not because it's scary, it's because the signal here is too poor and it's too stuck to play games." ”

A group of grass and mud horses ran over in Yu Fan's heart, 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 doing a part-time job?" ”

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

Yu Fan said solemnly: "Guide." ”
