Chapter 334

Others didn't know why, but hearing Fang Yang's shout, they ran back without thinking.

This time they retreated for a full hundred meters before stopping.

After Fang Yang stopped, he breathed heavily in place, while touching his chest and turning to look at the cameraman: "How is it, is my face discolored?"

The cameraman was confused: "Brother? What's wrong with you, you look fine!"

Captain Wang also hurriedly asked with concern: "Fang Yang, what's wrong, are you okay?"

Fang Yang hurriedly took out his phone to take pictures of himself, looking left and right, saying nothing, making everyone else confused.

It wasn't until he was sure he was okay that he breathed a heavy sigh of relief: "Damn! That was close, I almost died here today!"

The cameraman hurriedly asked: "Brother, what did you see, do you want me to call an ambulance for you?"

Fang Yang waved his hand: "I'm fine, don't worry. By the way, Captain Wang, I suspect that the five people before should have entered the mine cave."

Captain Wang was stunned: "How do you know?"

"Because at the place where it collapsed just now, there are several corpses below. Some were covered by stones and mud, and I didn't have time to look at the specific number carefully, but looking at the figure, it feels a bit like it, all wearing protective clothing, gas masks, and oxygen tanks!"

"And I also roughly know why they appeared here."

Everyone was shocked when they heard this.

"Wearing gas masks and oxygen tanks?"

Cheng Liang hurriedly asked: "If it's really them, then the big bags they carried when they went up the mountain were all oxygen tanks?"

Captain Wang frowned: "You said wearing gas masks, just looking at the figure is definitely not enough to confirm, I have to check it."

After speaking, he prepared to walk towards the hole.

Fang Yang hurriedly pulled him: "Don't! Don't go over, haven't you thought about why they died!"

Captain Wang's hair stood up, a palpitation appeared in his heart, and he couldn't help but retreat.

The cameraman asked curiously: "Brother, how are you sure they are dead, what if they are not dead? Maybe they need emergency treatment!"

Fang Yang shook his head: "Impossible! I can be 100% sure they are dead!"

As soon as this was said, everyone was curious and wanted to get the answer from him.

"Do you know why I was so scared just now?"

Everyone shook their heads: "Don't know!"

"Because the moment I got close, I smelled a highly toxic gas, called hydrogen cyanide gas."

Now everyone was even more confused, they hadn't heard of this stuff.

It happened to be the afternoon, and it was the hottest time of the day.

Everyone was sweating profusely after the nervous running just now.

Fang Yang looked at the hole with lingering fear and continued to explain: "This kind of chemical substance is impossible to appear here for no reason. According to the situation at the scene, I roughly guessed what these people came up the mountain for!"

Cheng Liang had a quick temper and was the first to urge: "What for?"

"Mining gold!"

"Gold!"

"Although washing the cave is highly profitable, it carries a huge hidden danger, which is the safety issue. Mine shafts that have been washed often become deadly, man-eating caves."

"You have to know that cyanide is highly toxic. Sodium cyanide itself is a white, highly toxic substance. It reacts chemically with water to release hydrogen cyanide gas, which is highly toxic—the bitter, almond-like gas I smelled earlier."

Upon hearing this, Team Leader Wang asked with concern: "Then... are you alright after inhaling it just now?"

Fang Yang waved his hand: "I should be fine."

"No!" Team Leader Wang's expression was serious: "This is no laughing matter. Li, hurry and call 120, explain the situation, and have them rush over to take a look."

"Yes!"

Seeing Team Leader Wang like this, Fang Yang couldn't refuse, so he smiled awkwardly and continued to explain: "The toxicity of hydrogen cyanide gas is 200 times higher than that of sodium cyanide. Once the concentration of hydrogen cyanide in the air reaches 0.3 milligrams per liter, a person only needs to take one breath to be poisoned and die immediately."

"Even if you are wearing a gas mask and carrying an oxygen tank, once you encounter an accident, it is impossible to survive."

Hiss~~

This sentence scared them all.

Although they didn't understand exactly how much 0.3 milligrams per liter was, they felt it couldn't be much, but to die immediately from poisoning—that was too terrifying.

Even the world's most venomous snake couldn't kill a person instantly!

Cheng Liang asked nervously: "So, you mean they all came to wash the cave? This is too scary. Can they be poisoned to death even while wearing gas masks and oxygen tanks?"

Fang Yang nodded: "Poison gas is only one aspect. At the very least, they could have run, but they didn't escape. Have you thought about why?"

"Why? Could it be that the poison gas was too thick?" Cheng Liang asked curiously.

Fang Yang shook his head: "The thickness of the gas is one thing, but it shouldn't be enough to kill them inside while they were carrying oxygen tanks. My personal speculation is that yesterday's earthquake happened to collapse the cave, sealing them inside completely. After a long time, they were bound to die!"

"You have to know that it's at least a hundred meters from the entrance to here. In such an environment, air circulation is very poor, and the hydrogen cyanide gas produced by their cave washing simply couldn't get out. That's why I could smell it the moment I opened the cave; I estimate the smell is even stronger in there now."

After hearing the analysis, Team Leader Wang nodded with a solemn expression: "What you said is very likely. Otherwise, it's impossible for them all to have collapsed inside. With oxygen tanks, they could have at least run out one or two. Does this mean we can't go over there at all? It looks like we need to get the biochemical department to come and help!"

The police officer behind him understood and immediately took out his phone to call the biochemical department.

After all, ordinary people simply couldn't solve this kind of thing.

Cheng Liang was a bit anxious; this was his factory, after all, and there was a warehouse nearby.

Fortunately, when they evacuated just now, the workers had also scattered.

Now, they definitely couldn't go over there; who knows if they would be poisoned instantly.

However, just at this moment.

Pop~~

This abrupt sound of a firecracker attracted everyone's attention.

Cheng Liang and the others from the fireworks factory stared at each other, not knowing what had happened.

The factory manager hurriedly asked the worker who had just run over: "What's going on? Where did that firecracker sound come from? Did someone drop a cigarette butt when you left?"

"How is that possible? We are all experienced hands and know the rules of this place. Whoever dares to drop a cigarette butt is risking everyone's life; we'd strangle them."

"Exactly. The people who went to the warehouse didn't even dare to bring lighters, let alone smoke."

"Could this firecracker sound be from somewhere else..."

However, the words had barely left his mouth.

Suddenly, a hissing sound came from nearby.

The factory manager was shocked: "That sounds like a fuse is burning? What's going on? Think carefully about who might have brought an open flame."

The workers were a bit panicked and tried to recall.

But no matter how they thought about it, they couldn't figure out where the problem was. They believed it was impossible for them to have brought an open flame into the warehouse.

Just as they were thinking anxiously.

A sound of a firework launching came.

Chirp~~ Pop!!

Chirp~~ Pop!!

Now, let alone the factory manager, everyone panicked.

The fireworks had actually been lit!

You have to know that this was a fireworks warehouse!

Once someone committed arson, it definitely wouldn't be as simple as just setting off fireworks.

If tens of thousands of large fireworks all exploded, what kind of concept would that be? It would probably be the largest firework display in the world.

And that wasn't the most terrifying part; the warehouse next door contained thousands of tons of ammonium nitrate.

Novel group 856323613

If the ammonium nitrate were ignited by the fireworks, the consequences... he didn't dare to imagine.

Not to mention whether it would collapse the mountain next to it, at the very least, the town at the foot of the mountain would suffer.

This place was home to military families; once an accident happened, it would definitely alarm high-ranking officers.

Then, not a single one of them would be able to escape.

Cheng Liang lost his temper and immediately rushed toward the warehouse, shouting: "Damn it, who is starting a fire over there? I'll kill you today!"

The factory manager and others also rushed over like madmen.

Fang Yang immediately shouted to stop them: "Don't go! The cave is storing a large amount of hydrogen cyanide gas. Didn't you see that even with oxygen tanks, they couldn't survive?"
