Seeing this, Bai Lu and Lao Feng immediately raised their arms to cover their mouths and noses.

I saw the liquid rolling back and forth in the plum petals, like dew drops on lotus leaves.

Seeing this, both of them recognized the origin of this thing.

Mercury!

Mercury is highly toxic, colorless and tasteless, and can evaporate at room temperature, which is harmful to the human body.

It is said that there was a large amount of mercury in the imperial tomb of the first emperor as one of the anti-theft measures.

"How can there be mercury in the mezzanine of mica? Could it be that someone did it on purpose? ”

Bai Lu looked at the surrounding mica wall with a puzzled face, puzzled.

Lao Feng poured the mercury particles on the ring on the ground, covered it with soil, approached the mica wall, and after carefully observing the structure of the mica wall, he leaned down and touched the trail under his feet with his hand.

A warm sensation came from his fingertips.

"Girl, let me ask you, where does this mercury come from?"

Bai Lu smiled wryly.

"Uncle Feng, you can stop me, aren't I also looking for the source of this mercury?"

Lao Feng waved his hand.

"I mean, where does this mercury come from?"

Only then did Bai Lu react.

"Oh, you say this, the scientific name of mercury is 'mercury', and its main mineral source is cinnabar."

"Cinnabar."

"Oh, this thing was called dansha, cinnabar, or stone cinnabar in ancient times."

Speaking of this, Lao Feng's eyes suddenly lit up.

"That's right, in this Helan Mountain, there is a cinnabar mine. Do you remember the 'little pony' who died before? ”

Bai Lu nodded.

"He has a cinnabar mining mine under his hands, and the business is very good, I also heard them talk about this at a wine party, saying that the cinnabar mine in Helan Mountain is better than the color of Sanxiang, but after so many years, the easy mining locations are almost mined, I didn't expect there to be here."

Hearing Lao Feng say this, Bai Lu suddenly realized.

Helan Mountain contains cinnabar ore, which is refined at high temperatures to produce mercury, that is, mercury.

Coincidentally, there are also countless coals in Helan Mountain, and they burn underground to form a fire that has not been extinguished for hundreds of years, which provides favorable conditions for cinnabar to turn into mercury.

The mercury in these mica crevices is not deliberate, but adapted to local conditions.

I have to admire the wisdom of the ancients and transform this ordinary mica mine cave into a "mirror city".

"Uncle Feng, your information is too crucial! Unfortunately, there is no way to tell anyone else right now. Broken! ”

Speaking of this, Bai Lu suddenly exclaimed.

"Oh, girl, something is shocking, I can't help but be scared now!"

Lao Feng stroked his chest, looking frightened.

"I'm sorry, Uncle Feng, I just remembered, in case Brother Qiang has been trapped here for a long time, according to his temper, why not pick up the axe and cut a hole in this mine?

If he goes down with this axe, the mercury in the inner layer of the mica will flow out, and the consequences will be unimaginable! ”

Lin Yi also thought of this question.

Moreover, he has now basically figured out the origin of these mercury, which is basically the same as what Lao Feng and Bai Lu speculated.

Cinnabar turns into mercury through the fire of the earth.

The gap of mica, like a thermometer, rises below, and the mercury continues to seep into it, all the way to the top of the mine.

Thanks to his long-term vision just now, he didn't cause a catastrophe.

However, Wang Qiang is definitely an unstable factor.

Now we must first pass the news to him as soon as possible, so that he will not pick up the axe and open the way on a whim.

Thinking of this, Lin Yi quickened his pace, continued to look back the way he came, and left marks at every intersection he passed.

Bai Lu and Lao Feng also followed the path they came, walking back, hoping to meet Wang Qiang at a certain intersection.

At this moment, Wang Qiang was already tired of jumping, so he couldn't move, sat cross-legged on the ground, took out a bottle of water from his bag, and drank it cleanly.

Holding the water bottle in his hand, he banged on the walls around him in a bored manner.

"Damn, if you come to a panting child, Lao Tzu can still handle it, this kind of place, like a labyrinth, brain-draining, thankless,, wait for Lao Tzu to relieve this breath, chop you all up!"

Cursing in his mouth, the water bottle in his hand immediately flew out, slammed into the mica wall, and bounced back.

The cap hit the wall right on, and the mercury inside changed.

It happened that Qian Sheng's shadow was projected on that wall, and the shadow was deformed, which attracted Wang Qiang's attention.

He immediately sat up, approached the wall, pressed the mica layer with his hand, and the mercury inside was torn apart, and when he let go, it gathered again.

"This thing looks like mercury?"

Wang Qiang was a mischievous master when he was a child, and he was curious about what was in the thermometer at home.

So, simply broke down and took a look.

After pouring it out, he found that it was a silver "little droplet", which was very funny, and he himself played with a small piece of mercury for an afternoon, until his parents came back from work.

He doesn't remember much of the joy he had been given to the mercury at the time, but that afternoon, almost all of his neighbors heard his heart-rending cries.

Later, some people said that the reason why Wang Qiang did not study well was probably because he inhaled too much mercury when he was a child.

Now, he is surrounded by mercury, which is nothing more than the so-called creation of people!

He had now completely dispelled the idea of using an axe to open a path on the wall, and began to regain his spirits, calm down, and go back little by little the way he came.

Judging by the shadows cast on the wall, several other people were on the move.

By this time, they should have realized that they had been separated from the army, and now they are all returning the same way, hoping to meet unexpectedly.

Lin Yi and Bai Lu were always paying attention to Wang Qiang's movements, judging from his projection, after a short stay, he also started to act, and did not make any surprising moves, and everyone's hanging hearts were finally put back in their stomachs.

But they all underestimated the power of this "City in the Mirror".

It was only a ten-minute walk just now, but now I have walked for almost twenty minutes, and I have not met anyone.

Everyone looked at the shadows projected in the surrounding mirrors, as if they were looking at several monitoring monitors with low definition, knowing the existence of the other party, but there was no way to communicate, and they didn't know where the other party was.

And that's not even the worst.

As they walked longer and longer in the "Mirror City", they could clearly feel the temperature under their feet gradually rising.

In addition, the surrounding mica mirror continuously reflects the heat, which accelerates the increase in temperature in the area.

The higher the temperature, the greater the mercury production, the faster the mercury in the mica crevices will climb, and the evaporation will increase.

If they can't find an exit from here anytime soon, all of them will be poisoned alive by the mercury here. (End of chapter)
