Chapter 144 Highly Toxic Substances.

After a discussion, several people decided to go to the back mountain to see what the so-called ghosts look like.

Under the leadership of the little boy, everyone climbed for more than ten minutes to the halfway point of the mountain.

Through the moonlight, you can see the spirit rooms located around.

The land here has not been developed yet, so there are still many graves made of earth.

There are many water-soaked paper money scattered on the ground.

Walking on it is like coming to another world.

At this time, any slight movement would probably scare them half to death.

After everyone shuttled through the graves for a while.

Suddenly!

The oldest child pointed at it and shouted excitedly: "Look! The grave is open again, and there is light inside."

Hearing this, Lin Yuan and others immediately looked in the direction of the finger.

Sure enough!

A tomb that looks a bit old, a rectangular cement tomb, the coffin inside has been pulled out.

The tomb is now lit, and you can faintly see a hole in the tomb, and I don’t know where it leads to.

The photographer was so scared that his legs went weak when he saw this scene. He trembled with fear and said, "Isn't this the passage to the underworld?"

Lin Yuan rolled his eyes at him and said, "What are you thinking about!"

Director Yu nodded and said, "It should be tomb robbers. But I wonder, this tomb doesn't look very old, and the coffin hasn't even been opened, so I can't understand it."

"Who said tomb robbers robbed this tomb? Didn't you see a hole in the tomb? I guess it's just a hole they dug." Lin Yuan pondered for a moment and explained slowly.

Director Yu nodded thoughtfully and asked, "What should we do now? Go over and take a look or call the police directly?"

"Let's take a look first. If it's really tomb robbers, they dug a hole here. I can't think of any other reason except to cover up and scare people."

After a brief discussion, the two took the initiative to walk towards the tomb above, no matter how the photographer protested.

However, when Lin Yuan approached the tomb and looked down at the passage, he couldn't help but sniff with his nose.

His brows gradually wrinkled, and he seemed to smell a bitter almond.

This puzzled him.

Where did this smell come from in the tomb?

But the next second, he suddenly thought of something.

His pupils suddenly shrank, and his face changed drastically!

He retreated madly, shouting at the same time: "Don't get close, don't smell, retreat quickly!!"

Everyone retreated without thinking.

They retreated dozens of meters before stopping to breathe heavily with lingering fear.

Director Yu came to Lin Yuan and asked solemnly: "What's wrong?"

"Something's wrong!" Lin Yuan frowned and replied thoughtfully: "This shouldn't be a tomb robber!"

"No?" Everyone exclaimed in unison.

"Yes!" Lin Yuan explained slowly: "If the tomb robbers dig a hole, they either use gunpowder explosion or pure digging, but no matter which one, it smells like gunpowder or earth."

"But just now, I smelled a bitter almond smell!"

Hearing this, the photographer nodded like a rattle: "Yes, I smelled it too. I felt strange just now. It was so pungent and unpleasant, like a chemical smell."

"That's right!! This is the smell of chemical gas!"

"This" Director Yu was also confused.

The development of the plot is completely different from what he imagined.

I thought it was a tomb robber, but it turned out that it was probably not. Could it be a ghost?

"Even if there is a chemical smell, there is no need to run? Could it be poisonous?"

Lin Yuan nodded seriously: "This smell is very similar to a gas in my memory. It is called hydrogen cyanide gas and is highly toxic!!"

Hearing the word highly toxic, everyone's face changed instantly and turned pale.

The photographer's pupils suddenly dilated, and he quickly covered his mouth and nose, hesitatingly asking: "Then we just inhaled it, are we poisoned?"

"Not really!" Lin Yuan explained with a smile: "The smell we smelled is very thin, it should be coming from the cave."

"This gas has a very low boiling point, only 25 degrees Celsius. Once inhaled, it will cause mild poisoning, dizziness, nausea, chest tightness, etc. If the concentration is high enough, one breath can immediately cause poisoning and death. Even with a gas mask, you still can't survive!"

The photographer was stunned.

The first sentence instantly made him feel relieved, as long as he was fine.

As a result, the next sentence told him that the concentration was too high, and one breath would be enough? Wearing a gas mask is useless?

How terrible is this poison?

The netizens in the live broadcast room were also shocked.

——[Hydrogen cyanide gas, my God, this thing is not accessible to ordinary people at all, why is it here, fortunately those children were timid and didn't come to see it, otherwise they would probably all die. 】

——【Is it really that scary? Is it more poisonous than a cobra? Can a gas mask kill you? Anyway, I don’t believe it. 】

——【It can only be said that they are ignorant. The chemical toxins developed by humans are far beyond your imagination. This kind of poison is no match for the cobra, even the most poisonous snake in the sea. 】

——【I don’t understand. Aren’t you here to sell the house? Why do you feel like you are here to explore? 】

After listening to Lin Yuan’s explanation, everyone finally understood why his expression was so exaggerated and why he ran so fast.

Just kidding, if you are not afraid at this time, you are stupid!

But what puzzled everyone was why there was such a toxic gas in this cave. Could there be something special underneath?

In this regard, Lin Yuan slowly explained: "Originally I was not sure it was hydrogen cyanide gas, but when I thought of another special place on this mountain, I was immediately sure."

The photographer asked in surprise: "What special place?"

"Abandoned gold mine!!"

Lin Yuan continued to explain: "With an abandoned gold mine here, it is not difficult to understand the presence of this gas. I can now be sure that this hole was not dug by tomb robbers, but gold thieves!!"

"Gold thieves?" Director Yu and the photographer were both confused, and asked with a puzzled look: "Didn't you say abandoned gold mine? How to steal gold?"

Looking at the two people's expressions like curious babies, Lin Yuan smiled and asked back: "Abandoned gold mine, why is it abandoned? "Again," The photographer replied: "The gold mine is finished, so it is abandoned." Lin Yuan shook his head with a smile: "No!" "Once the large particle environment is collected, only the very small gold is left. They are mixed with soil stones. Not only are normal mining difficulty, but the cost is also high. At this time, it will be lost without the amount of mining. Granules, but you also said just now that artificial mining is difficult, the cost is high, and it is not cost -effective. What else is it necessary to steal it? "
