"Why are all the bones with their mouths open?"

Haoyu muttered to himself.

A SWAT officer squeezed in.

"I took the 'Dynamics of Remains' in Forensic Medicine...... I think this is the state that caused all the bones to appear in the moment before they died...... There are generally two possibilities...... One is extreme fear, which is mentally stimulated and requires you to open your mouth...... On the other hand, there is having to open your mouth, as you instinctively do when you have trouble breathing. ”

These words made me feel like I was empowered.

"That's right! Do you think there will be a situation where these people can't help themselves before they die, they can't leave, they can't see the way clearly, and they ...... And in the end, before he died, he couldn't breathe. ”

Haoyu took a deep breath: "The situation you said may make the body appear in this state when the corpse dies - under what circumstances can everyone be unable to see or breathe?" ”

At this time, a special police officer who had never opened his mouth opened his mouth: "You say these people will not be murdered?" ”

"Murder?" Haoyu was obviously stunned for a moment, "Brother Fan, you ...... How do you think it all? ”

The SWAT looked in his thirties, with a little long hair, a sloppy look, and a little stuttering when he spoke.

"Look! Over here...... This pungent smell of cement was everywhere here, and it was ...... Could these people have been trapped by another group of people with this cement powder?

Suppose the people on the outside put on something like a disinfectant mask, and they keep spraying cement powder at the people inside, and then another group of people sprinkles water into the crowd...... Such...... In this way, the cement powder and the water are mixed together, and it becomes cement, because at that time there was cement powder with a pungent smell everywhere, and the people in it had to struggle to cover their mouths and noses, and at the same time they could not see anything......"

After saying this, everyone looked at him blankly.

This special police officer, known as "Brother Fan", obviously didn't expect that after he finished speaking, everyone would have such a reaction, and he was also stunned, looked around, and laughed: "What's wrong?" Small table...... Several? ”

"Brother Fan, what you said makes sense!"

Another SWAT officer then asked, "But why kill these people in this way?" ”

This stopped everyone again.

Haoyu thought for a while, and said slowly: "In fact, there are similar examples in modern times, for example, in the fifties and sixties of the last century, a large number of people in a mountainous area in southern China had leprosy, at that time this disease was very contagious, and there was no rule of law at all, so at that time, the higher authorities secretly sent a force to this village, and couldn't help but say, first shot with guns from a distance, and then everyone wore gas masks, sprinkled a large amount of white ash on the corpse, and then sprinkled water. ”

"What do you mean?"

Lao Kong's voice trembled a little.

"Imagine if these corpses sealed in cement also had some kind of highly contagious disease?"

"Contagion?"

I didn't think about it.

"Who do you mean, this entire underground Jinan City was sealed because of some kind of infectious disease?" I then asked.

Haoyu smiled slightly: "I'm just guessing this - but it's not a random guess, in addition to the evidence just now, there is another point - you smell these cements carefully, don't you think this smell is a little familiar?" ”

"I'll just say that the cement smell is a little pungent......"

Without waiting for me to finish, Haoyu frowned slightly: "Brother, you smell carefully, what is the smell of this pungent smell in the cement!" ”

Well?

I sniffed it carefully, not to mention it, it really felt a little familiar, but for a moment I couldn't remember what it was.

"It's sulfur dioxide! It's sulfur dioxide in a solid state! ”

I didn't notice which SWAT officer screamed, causing everyone to look at him.

I looked at Haoyu.

At this time, Haoyu nodded slightly: "Yes!" ”

Sulfur dioxide is the most common, simplest and irritating sulfur oxide, a colorless gas, and one of the main pollutants in the atmosphere. This gas is ejected when volcanoes erupt and sulfur dioxide is also produced in many industrial processes.

Since coal and oil usually contain sulfur, sulfur dioxide is formed when burned.

When sulphur dioxide is dissolved in water, sulphurous acid is formed. If sulfurous acid is further oxidized in the presence of PM2.5, sulfuric acid will be formed quickly and efficiently.

This is one of the reasons for concerns about the environmental effects of using these fuels as an energy source.

Sulfur dioxide is chemically complex, and different temperatures can be used as aprotic solvents, Lewy acids, reducing agents, oxidants, redox reagents, and other functions.

Liquid sulphur dioxide can also act as a free radical acceptor.

For example, in the presence of azodiisobutyronitrile radical initiator, polysulfone is obtained by reacting with ethylene compounds. Liquid sulfur dioxide can be chlorosulfonated with chlorine and alkanes under light to form sulfonic acid in the presence of oxygen.

To put it simply, sulfur dioxide has a strong anti-virus ability, but if it is inhaled into the body for a long time, it is harmful to the human body. ”

The SWAT took a deep breath and said slowly: "I actually chose to use the sulfur dioxide of the object to kill the virus...... What kind of poison is it? ”

Haoyu sneered: "Have you forgotten the zombie disease that is giving us a headache now?" It seems that the source is here! ”

One of the SWAT officers exclaimed, "Not good! In this way, Director Hu, wouldn't they be very dangerous, or...... Or already ......"
