Chapter 281 Hunting of R600A

It is often not people's stupidity that kills people, but their own cleverness.

Yu Fan found the strange Bi Mawen suit that he had taken off and piled it at the foot of the wall. Yu Fan was just about to rush to the foot of the wall to investigate this piece of clothing, but he stopped.

The prudent Yu Fan knew that the more he acted alone, the more he had to reserve the way for himself.Such scenes often appear in movies and novels. The protagonist finds the treasure in the secret room through untold hardships. When he is in a hurry to open the treasure chest, the bad guys come and close the door of the secret room, and the protagonist is trapped in the secret room to death.

In case of such a nonsense ending, Yu Fan was careful, and then left the room, looked around in the alley to see if anyone was following behind to make trouble.Then I went back to the room and moved an old washing machine on the ground to block the door, so that the back road would not be cut off.

Only at this time did Yu Fan alertly go to the corner of the wall and pick up the clothes. I really don't know where he got them, it must have been painstaking.

At this time, Yu Fan found a word on the inside of the collar of his clothes. It was the Arabic numeral "5" written with a red watercolor pen. The font was not too small. What does it mean?Such large characters have already affected the beauty of the clothes, especially for such "rare" clothes, such scribbles are really a pity.

Other than that, there seemed to be nothing strange about this room, it was just an ordinary electrical repair shop.

It's really a pity, this strange man must have been here just now, and he almost caught up with him, damn it!
Yu Fan looked at the door he had kicked down again. What's worse, when the strange man came back, he would know that he had been there. He would be more cautious next time and harass Yu Fan in a more subtle way.

The cold air from the air conditioner continues to blow...

etc!What did Yu Fan suddenly discover, sixteen degrees?sixteen?

This number has a unique meaning to this strange man, because the atomic number of the sulfur element in the "Sulfur Atom Electron Layer Map" that he keeps sending to Yu Fan is exactly sixteen!

There is something strange here!Yu Fan looked around again, and there were two washing machines, eight refrigerators with open doors, and six televisions on the ground.The number of electrons in the first shell of the sulfur atom is two, the number of electrons in the second shell is eight, and the number of electrons in the third shell is exactly six.Two, eight, and six just correspond to the sulfur atom! !

And the number on the collar of that weird dress! !Yu Fan went over and picked up the collar and looked at the number carefully.

ah? !This... This may not be the number "5" at all, but the letter "S"! , S exactly represents sulfur in the element symbol! ! ! !

sulfur?Why sulfur?What is so special about this element?The air at this moment was extremely quiet, only the hissing of electrical appliances in the room, and Yu Fan's own heartbeat.

Why is this room arranged like this?Is it so?or……

Specially arranged for Yu Fan? !

Is this inviting you into the urn and catching turtles in the urn?Yu Fan thought in horror.

A sound of "beep~" interrupted Yu Fan's thoughts.The sound was coming from inside an open refrigerator.

what sound?Yu Fan followed the sound and walked over.

The cabinet of this refrigerator is very clean, there are no sundries, only a small note inside.Yu Fan took out the small note from the refrigerator. There was a line of small words on the small note, which was very, very small, and the light in the room was very dim, so it was impossible to read clearly.

Yu Fan looked around for a while, then took out his mobile phone, turned on the flashlight mode, and took a closer look at the note, only to see that it was neatly written: "When you see this line clearly, you are not far from death Already..”

Yu Fan suddenly raised his head!With a snap of his fingers, Yu Fan suddenly realized the danger! !The hissing sound I heard just now is not the sound of electrical appliances at all!It's the sound of gas leaking!There are eight refrigerators in the room, and each refrigerator has its own refrigerant!That is R600A!

The introduction of R600A automatically appeared in Yu Fan's brain. R600A, generally refers to isobutane, which is a colorless flammable gas at normal temperature and pressure, with a slight odor.Melting point -159.4°C.The boiling point is -11.73°C.Slightly soluble in water, soluble in ethanol, ether, etc.It mainly exists in natural gas, refinery gas and cracking gas, and is the general refrigerant of refrigerators.Form explosive mixture with air, the explosion limit is 1.9%~8.4% (volume).

In the worst case, the refrigerants of the eight refrigerators in the room are maliciously leaked at this moment!The whole room is now full of isobutane!Yu Fan also remembered that the other substance besides rosin that he smelled just now was isobutane!So much isobutane only needs a small electric spark to detonate!The power of a refrigerator's refrigerant explosion is equivalent to half a grenade! (Not counting shrapnel damage), the temperature of the air conditioner is set so low, is it because of the fear that the electrical appliance will overheat and cause an explosion before Yu Fan arrives?

It took Yu Fan [-] seconds to figure out the above thinking.The "beep" just now, couldn't it be the detonator?

Damn!Oops!run!
Boom! ! ! ! !A loud noise came from Jixiang Village.

Yu Fan was thrown out of the door with a huge heat wave!
Yu Fan felt as if the whole world had gone silent. This was the second explosion he had encountered in the past few months (the first time was in Chapter 120).

Yu Fan's ears were ringing from the explosion, and his brain was buzzing continuously. If it wasn't for his quick escape just now, Yu Fan would have been buried in the sea of ​​flames.Yu Fan struggled to get up. Fortunately, he was wearing thick clothes, so he didn't seem to be seriously injured, but his clothes were already torn. Yu Fan panted heavily, looking at the raging fire in the house.

People in Jixiang Village were awakened by the loud noise and ran out to see what was going on.

Yu Fan blinked, and his hearing gradually recovered. He saw the weird eyes of the people next to him, and his first instinct told himself that now it was a scholar who met a soldier, and he couldn't explain why. He wanted to tell the police what happened. Clearly, it's too difficult, and now this person is so insane, if he is arrested and investigated, his family members may be in danger, no, we can't let the family members get involved now.

Yu Fan pulled up his collar, covered his face, lowered his head, and walked quickly to the outside of Jixiang Village...

In the past few months, Yu Fan encountered several dangers. From the initial panic to the current calmness, Yu Fan has grown tremendously mentally.Having just experienced another catastrophe of life and death, Yu Fan has even gotten used to it.Before I could relax, I thought about the next step.I thought the opponent was a weird and stupid freak, but now it seems that I am the fool who pretends to be smart.

After walking out of Jixiang Village, Yu Fan will definitely not be able to go home directly with his current disheveled appearance. He can only go back if he finds a safe and trustworthy place to tidy himself up again.

Yu Fan took out his mobile phone, and the protective film on the mobile phone screen had been broken. Yu Fan tore off the protective film, but the screen was still intact. If you want to play like this, then I will accompany you to the end!"

Yu Fan dialed Shi Yi's phone.
