Zhizhizhizhizhi...

Li Heng glanced down at the remains of the old explorer and took off his camera without any expression.

He didn't have a good impression of this guy, but he wasn't as disgusted as Warner.

In the final analysis, this guy just has a good reputation and loves to brag about spectacles. In today's terms, he just creates topics to attract traffic.

But compared to those bandits who specialize in stealing cultural relics and destroying the cultural heritage of other countries, it is still much better.

At best, he is a candid photographer who likes to go into other people's homes to find big news.

It seems quite annoying to think like this?

So he squatted down and rummaged through this guy's remains, continuing to collect some "residual value."

Needless to say, he actually found something else.

A kraft paper package wrapped in layers. When you open it, you will find a small metal wine bottle, a lighter and a notepad inside.

Fluorite is also called fluorite, and in ancient times it was also called warm palace stone. There are many variations, most of which can emit light on their own, while some require external energy, such as sunlight or heating.

Because the last record was the last information he had during his lifetime. What Li Heng cared about was what he saw and knew before he died.

"A very regular sound, like the... pulse of the earth!"

But just as he was about to step over the steps to the other side of the abyss, he suddenly turned his head and looked to the other side. The distant dark area on the other side of the steps was not enveloped by this light source.

If nothing else goes wrong, it is most likely due to artificial intervention. Someone gathered a large amount of fluorspar in one place and created a light that can last forever underground.

The features belonging to the White Lotus Sect also continue to appear on stone pillars, rock walls and the ground, and some places have even been carved and polished into steps.

He immediately leaned to the side and put his ear against the stone wall, quietly waiting and searching, like a scanning sonic radar.

Then the sound lasted for about 1.5 seconds and then disappeared, followed by a long period of silence, and then appeared again after about half a minute.

Li Heng made such a conjecture immediately. The environment in front of him was filled with a dark red luster, which was very weak, but for people with sufficient eyesight, it could barely illuminate the way forward.

And behind one page, there is a large blank space with only one line of scrawled English - lets go China!

A cluster of richer red light not far away attracted Li Heng's attention. The brightness of this cluster of red light indicated that it was far different from the density of other rock formations in the underground space.

And the ambient temperature has been rising all the way from the tunnel to here, so it is more reasonable to guess that it is underground magma.

Li Heng's eyes gradually brightened, and his aura became calmer and deeper, like a big lake with no bottom.

However, the underground tunnel that Li Heng is passing through is vertically downward. It is a tunnel with a certain slope, and the slope is not large, so the feeling inside is still similar to flat ground.

The fluorspar here converts internal energy into light energy when heated.

Li Heng whispered to himself, although he was still in the cold darkness, he could feel the slight changes in heat.

Tick ​​tock—tick tock—

At this moment, he suddenly heard the sound of water dripping.

Li Heng frowned slightly and felt a little strange, something he didn't understand, and then he directly switched to "Coming to China?"

There was no hesitation in continuing to explore, but Li Heng was now concentrating on guarding against all possible hidden threats.

So he directly took the book away, opened the cover and turned directly to the last few pages with written records.

This was a natural alert caused by some subtle changes that he noticed.

The changes in ground temperature he now perceives are not purely caused by the relationship between ground temperature and depth.

And could this faint voice now be the reason why he was so panicked?

There is more than one such ball of thread, which shows that he wanted to draw a pattern that could simply describe this thing, but maybe after drawing it several times, he felt that it was not very good and difficult to describe, so he crossed it out again.

Maybe it's groundwater, but maybe it's something else...

“It’s getting hotter”

In other words, the prerequisite for light here is heat first, and the causal relationship between the two is sequential.

After these three words, there was a messy pattern, like a big ball of thread, which was the trace of him crossing out the original pattern.

Li Heng felt like he was standing on a large platform. It was similar to the feeling he had just entered the White Lotus Sect mine before, but it was different because the mine in the mountain was dark, but there was light here.

Until he had walked at least several hundred meters in the underground tunnel, his hand touching the rock wall shrank slightly.

Li Heng's eyes suddenly lit up. He didn't pay attention to anything else, but the things with written records were what he cared about the most.

But he believed that he heard it right. With his current hearing, he could catch the slightest movement.

This is a kind of stone crystal attached to the rock formations in large quantities, emitting a faint dark red light, illuminating this otherwise dark space, forming an extremely unique underground scene.

But this was not a big problem. As Li Heng continued to move forward, this superficial problem was quickly solved.

Appeared! This is the movement.

"Um?"

Some kind of heat source exists ahead!

As he continued to approach, the temperature continued to rise, and soon reached a level where ordinary humans could feel warmth on the body surface.

It was like a very elastic rubber expanding and contracting while rubbing against the rock.

"It seems that this is the so-called place where immortals are born, where the real forbidden place mentioned by the well is."

So he knew that his depth in the vertical direction had not increased much, so the temperature change would not be that drastic.

I probably couldn't figure it out for a while. Although the environment here is quiet, even quieter than the library, it is indeed not suitable for reading.

But now everything is calm again.

And when he saw the source of these dark red lusters clearly, the speculation of lava light source could be rejected.

Was there something further down here that frightened him?

Gu——chi——

He turned to the last few pages with text and looked at them briefly under the light. Then his first eye was attracted by a line of text on the third to last page.

These three characters are still written in traditional Chinese, and the strokes are quite complicated, but the hooks and strokes are perfect. It can be seen that this Alai Jones is actually very familiar with Chinese characters.

Even the possibility of an extinct volcano existing is very low.

"Fluorite crystal, or some kind of isomer"

As Li Heng slowly approached the dense red light, the artificial traces that once disappeared also appeared again.

He glanced back at the explorer's body on the ground. This final death posture meant that he was probably very nervous and excited when he came out of the passage, so that such an experienced adventurer was in a panic.

Such a simple routine killed me on the spot.

Li Heng thought so in his heart.

Or is this thing called [Pressure of the Dragon] the goal of his trip?

It was a line of Chinese in bold and black.

Maybe what he's looking for is there, deep inside.

Li Heng held his breath and concentrated. Just now he was sure that his eardrums had caught a trace of sound in this dark and closed underground space.

Just after he put the notebook in his pocket, his right ear suddenly perked up.

Most of the records in this notebook are written in English, using a blue ink, but on the last few pages, there is an unusual mark.

A series of steps appeared in front of him, leading directly to the place where the sound of water dripping came from, and everything here was shrouded in dark red light, giving it a dreamy and terrifying feeling like an abyss or prison.

This change is temperature.

Not only Li Heng also knew clearly that it is unlikely that there are volcanoes under the Qinling Mountains. The geology and landforms here are themselves formed by sedimentary rocks, which were later squeezed and stretched by plate movements to form a metamorphic rock mountain system.

What I said just now may need to be changed, it doesn't seem so quiet here.

This made him feel slightly uncomfortable, although from a geological point of view, at thirty meters underground, the temperature would rise by about one degree for every hundred meters dropped.

"Volcanic lava?"

"Suppressing the Dragon King"

In a place like this, even if the sun's rays can bend one hundred and eighty times, it cannot shine in, so the light here can only come from underground.

Yes, I don’t know how much deeper the underground is than the Bailian Mine, but there is still light!

He found that these dark red lusters came from very fixed areas, unlike magma, a fluid with certain fluidity.

Until he moved forward at least a thousand meters and completely left the cramped tunnel and came to a more spacious space.

But it's not completely dark there, there are pairs of red light spots crowded together densely there.

One pair, two pairs, three pairs... ten pairs, a hundred pairs, a thousand pairs... countless red dots, like pimples crowded on a dark face.

At the same time, along with the breath of life that had not been seen in many years, there was an incomparable mixture of noise and chaos——

Squeak squeaky and creak squeaky squeak !!!!!!!
