The old woman was speechless and was dragged away by the police officer handling the case.

Although there are many people in the bureau, things are still going on in an orderly manner, and the trio of Yu Fan can't help much, so they discussed taking the train back to XA today, and they can rest at home for a Sunday. Guo Na booked tickets for three people, and the three of them went to say goodbye to Zi Yan.

Chen Jiaoyang: "Brother Ziyan, we can't help here, let's go back first, and then there will be someone to connect with this side for the next step." ”

Zi Yttrium: "Okay, we won't keep you any longer, even if we send the surrounding police to help, but the interrogation of so many people will still take a lot of time." I'll take you to the station. ”

Chen Jiaoyang: "No, no, let's just take a taxi back by ourselves." ”

Zi Yttrium: "It's okay, drop by." I just got the news in the morning that I found the staff dormitory of their LZ branch, and those low-level minions who didn't come to the meeting last night live there, and my colleagues have gone to arrest them early in the morning, and they have arrested those miscellaneous soldiers, and it is completely done. They live very close to the high-speed rail station, and I sent you off just in time to meet up with my colleagues. ”

Chen Jieyang said, "Okay then," he looked at his watch again, "Actually, it's still early, we can go to their dormitory with you and watch you clean up these miscellaneous soldiers, which can be regarded as a beginning and an end." After Chen Jieyang finished speaking, he looked at Yu Fan, and seemed to be asking for Yu Fan's opinion.

Yu Fan nodded. Let's go.

Along the way, the car radio also broadcast: "Last night, the police of our city and the XA police jointly cracked a large-scale pyramid scheme case...... "The sunlight outside the window also shone on Yu Fan's triumphant face through the car window.

When they arrived at the scene, there were already a lot of police cars parked downstairs, and many police officers came down from the upper floor with the people they had just captured. Zi Yan went up to inquire about the situation, only to learn that this building has a total of 5 floors, two households on each floor, almost all of them are rental houses, and they are all rented to this MLM organization, and there are people from the 150th MLM gang living in a small building! On average, there are about 10 people in a room!

This time it was really very lucky, although it was a night away, but miraculously there was no leakage, and none of the people who should be arrested ran away.

Guo Na said: "It's really ironic, the trees are falling and scattered, and these people who were arrested at the meeting didn't even bother to report to these people." “

Chen added: "Maybe they thought in their hearts: 'I've been arrested, why should you minions be so good?' ’”

Yu Fan said quietly: "I don't want to live well as my own people, a typical superior personality disorder." When I was in junior high school, there was a time when 20 boys in the class went to an Internet café to surf the Internet, and the teacher came to arrest people, and the teacher only arrested one classmate who was sitting outside, but this classmate took the initiative to confess that there were still 19 classmates in the Internet café. Annihilated. This is also the reason why when arresting corrupt officials, as long as one is caught, the entire chain of interests can be easily pulled out. ”

Just as a few people were chatting downstairs, an urgent voice came out of the police intercom: "There is a problem in room 501!" We knocked on the door and the door didn't open, there was a fight inside! ”

The commander downstairs said calmly: "Break the door!" ”

As soon as the words fell, clang! The door opened, but it was ......

The door opens from the inside! Three people rushed out of the room, and the three of them ran downstairs like crazy, muttering, "Damn, this person is crazy!" Of course, these three people naturally couldn't run far, and as soon as they went out, they were pressed down by the police guarding the door.

Another hurried voice came from the intercom: "Three people ran out of the house, subdued, but they said that there was another person in the house who lit the gas canister!" Now we can also smell a strong smell of gas at the door. ”

Everyone heard the news like a bolt from the blue!! Everyone understands the reality that the problem is serious!

Zi Yan didn't say a word, and strode upstairs. Yu Fan's brain was stunned, he thought it was just a small matter, but he didn't expect the situation to escalate without warning.

It is not terrible for the gas tank to be ignited, under normal circumstances, the gas tank will not explode even if it is ignited, as long as the valve is covered with a wet towel, and then the valve is turned off clockwise, the reason for using a wet towel is to prevent burning your hands. Some people on the Internet say that the fire should be extinguished first and then the valve closed, otherwise it will be negative pressure backfire, which is a lie. Remember, close the valve first! Close the valve first! Close the valve first!

There are four situations that can cause a gas tank to explode.

First, the cylinder is overfilled, which is the main reason for the explosion of the cylinder.

Second, the cylinder is burned upside down, which is another important reason for the explosion of the cylinder.

Third, the cylinder is sick to work. If it is used for a long time, there is a lack of inspection, maintenance and repair, the cylinder will be rusted, perforated, cracked, resulting in the loss of compressive strength, and it is easy to explode when it encounters high temperature, extrusion or collision.

Fourth, some users use hot water to pour, fire to bake cylinders and other methods to promote liquefied gas fire, which is also very dangerous! In particular, burning the cylinder with fire will make the cylinder lose its due strength, which can easily lead to the explosion of the cylinder.

The explosive power of a household gas canister is equivalent to 150 kilograms of TNT explosives. The explosion of a gas tank often brings two damages, the first is the physical explosion of the tank rupture, and the liquid LPG in the tank instantly expands 250-300 times into a gaseous state, producing a shock wave, like a landmine explosion. Then, the gaseous petroleum gas is quickly mixed with the air, and when its concentration in the air drops to 3%-11%, it will produce a chemical explosion when exposed to an open flame, producing a huge shock wave, and if a person inhales this explosive gas, the respiratory tract and lung tissues will be burned.

Before he could think about it, Zi Yan had already run up to the fifth floor and rushed into the door of the room, only to see a gas tank lying at the door of the room, and the body of the gas tank was also surrounded by flames, blocking the door of the room like a wall of fire, making it impossible for people to enter, and through the wall of fire, he could vaguely see someone in the corner of the room, Zi Yan picked up the walkie-talkie and shouted: "I saw the gas cylinder, how can this thing be turned off?" ”

Downstairs, Yu Fan rushed to the police officer next to him, grabbed the walkie-talkie, and shouted: "Is the bottle standing or lying down?" ”

"Lying down! Like a fireball," yttrium shouted.

This is the most dangerous situation, because the fuel leaking from the upside-down gas tank will ignite and burn the bottle and the ground, and the heating of the ground will heat the bottle, in which case the gas tank will explode after four minutes of burning!!

Yu Fan picked up the walkie-talkie and yelled: "Run!!!! ”

As soon as the words fell, a loud explosion sounded.

Bang!!!
