It is a mysterious stone room, the size of a basketball court, not paved with masonry, but the floor and walls are very smooth.

The top of the stone chamber is very high, and it is also very irregular, pitted, uneven, and even stalactites hang down, like bamboo shoots, more like spikes, as if they can fall down at any time and pierce the people below.

This stone chamber was supposed to be an underground cave, but it was later transformed into this.

It's hard to imagine who went to such great lengths to renovate such an underground stone chamber. The most incredible thing was the fire gushing out of the underground pit in the center of the stone chamber.

Draw out the earth fire, incinerate the furnace, how did the owner who built this place do it?

Also, what is the role of the nine square tripods around here?

Before, the second master and Yan Xiaoying said that this place was the ancient tomb of the demon general, but how do I think of this stone room, it seems to be the place where the ancients practiced alchemy? It doesn't look like an underground tomb at all.

Yan Xiaoying picked up an iron claw flying rope from the well, guessing that someone climbed up from the well before us, and this person was not the second master.

As far as I know, only the second master, the camel couple, Liu Xiaojiao and me, and Yan Xiaoying and others came here.

Liu Xiaojiao was taken away by the flying centipede before, and now I am afraid that she is more than lucky, and the second master did not bring an iron claw flying rope, so the only ones left are the camel couple and the two.

The second master said before that the purpose of the camel coming here was to find the elixir treasure left by the Demon General's tomb.

And judging from the current situation, this stone room may be the place where the demon general alchemy.

In other words, the camel couple may have gotten what they wanted.

Yan Xiaoying and I took a cursory glance around the stone room, but we didn't see any figures, let alone any traces of flying centipedes.

It's just that we followed the signal of the second master, and according to the self-speculation he left outside the stone crack before, he himself should have entered here......

There were a dozen stone pillars in the stone room, and there were several oil lamps embedded in the pillars, and because the light of the fire gushing out of the pit was too faint to be light, I went to one of the stone pillars and buckled down an oil lamp.

The oil lamp is green and yellow, resembling a bird, and is made of copper, which looks like the copper cups used by the ancients when drinking.

There was solidified and blackened grease inside the lamp, I don't know what kind of grease it was, and a wick extended out.

I stretched the wick and didn't dare to light it casually, because I remembered the ghost oil lamp I had lit when I was in Changqingguan, and lighting the oil lamp almost killed the old fat.

"Yan Xiaoying, do you think this bronze lamp can be used? The grease inside seems to be a little strange, why is it black? ”

Yan Xiaoying took the bronze lamp from my hand and sniffed it with her nose, shook her head after half a ring, and said, "I don't know what these solidified grease are made of, as for how it turned black, it may be because it has been stored for too long, right?" ”

"Is there any danger?" I asked.

"I don't know...... However, we don't have lighting tools in our hands, so this bronze lamp may still be useful, so let's try it......" Yan Xiaoying said as she took the oil lamp and walked towards the black ding in the center.

We didn't have any ignition tools, and the lighter that Lao Fei gave me before was also lost, but fortunately there was a fire gushing out of the ground here, which could be used to light a bronze lamp.

I followed closely behind Yan Xiaoying, this place was dangerous, the two of us didn't dare to leave too far, and besides, we still had corpse ropes tied to each other.

The stone room was quiet, so quiet that only the sound of our heavy breathing and footsteps as we walked.

The two of them walked towards Hei Ding, and on the way, I shrugged my nose and moved, and smelled a strange smell of meat wafting from Hei Ding's location.

Originally, I had been half-full from drinking spring water before, but when I smelled the smell of meat, my stomach suddenly croaked.

"Strange? How could the smell of meat waft from the black ding? ”

As I walked towards Heiding, I wondered: "If this is the alchemy room of the demon general, then what wafts out of Heiding should be Danxiang, how can it be meaty?" ”

"Isn't that demon general dead? Knowing that we were coming here, did you deliberately use Hei Ding to greet us with a pot of broth? ”

"Don't talk nonsense!"

Yan Xiaoying glanced at me and said, "Before, the second master said that there is a demon general tomb here, although we don't know the origin of the so-called demon general, but I think it is also an ancient figure who doesn't know how long ago it existed. It could have been a thousand years ago, or even thousands of years ago. Do you think there are people in this world who live for thousands or even thousands of years? ”

"Humans may not be able to, but didn't you say just now, the other party is a demon general!" I said.

"The demon general may not necessarily be a demon, and even if it is a demon, I have never seen anyone who can survive for such a long time. I suspect that this so-called demon general is actually a human, because of the layout of the stone chamber here, everything seems to be made by humans. ”

"The ancients were superstitious about feudalism, and when they encountered something that could not be explained by common sense, they attributed it to the gods or ghosts. In fact, where are there so many gods and demons in this world? Even if there is, they are just spirits that have survived for a long time, like the Flying Centipede King and the Golden Rooster and the snake that hibernated in the reservoir before, they are all flesh-and-blood creatures, but they have survived for a long time and become spirits! ”

"What is the explanation for the existence of the Yin Division?" I shook my head and asked noncommittally.

"Yin Si water is deep, its existence is not to mention us, I'm afraid even the ancient sages can't say it clearly, all in all, when you encounter people and things in Yin, try to stay away, otherwise you will get into trouble, and the consequences will be unpredictable."

"I ......"

"Don't talk so much nonsense, we say this black ding is strange, why did you get to the yin?" Yan Xiaoying glared at me and said, "Why didn't I realize that your person's phenomenal power was so rich before? The demon will stew a pot of broth to beckon us, do you think this is possible? ”

"Oh!"

I touched my head and sneered, "Don't I think the atmosphere here is too oppressive, just make a joke?" Don't take it seriously. ”

"I really don't know what's going on in your head, but you're still in the mood to joke at this time?"

Yan Xiaoying shook her head and seemed to be speechless to me, and the two of them quickly came to Heiding.

At close range, you can really feel the heat of the burning body, the flames under the black tripod are bright and extinguished, the pit is only the size of a palm, and if you look closely, you can find that there is a pitch-black copper pipe buried inside the pit.

In addition to the smell of meat emanating from inside the black ding, we also smelled a faint smell of sulfur, which gushed from the copper pipes in the pit.

Yan Xiaoying leaned down and handed the copper lamp to the flame, and at the high temperature, the wick was suddenly touched.

"The copper lamp can still be used!" Yan Xiaoying picked up the lit copper lamp and said in surprise.

Seeing that the copper lamp in Yan Xiaoying's hand could be lit, I was also happy in my heart, with the copper lamp lighting, at least I would no longer be like just now, like a blind man who couldn't see anything.

In other words, with light, our safety is also more guaranteed.

After calming down a little, looking at the flames gushing out of the copper pipe in the pit under the black ding, I became curious and asked Yan Xiaoying: "How did you say this earth fire was formed?" ”

Yan Xiaoying muttered, "It may be a magma fire drawn from the depths of the ground, or it may be a natural fire. ”

"Natural fire?"

Yan Xiaoying smiled bitterly: "You have read more than me, you should know that there is combustible natural gas stored underground in some places, and once it is ignited, it will not be extinguished even if it burns for hundreds of years." ”

"However, judging from the hot springs gushing out from under the spring pool just now, this may be magma fire, that is, real earth fire!"

Generally speaking, there are two reasons for the formation of hot springs.

One is formed by magmatism in the earth's crust, or accompanied by volcanic eruptions, and the extinct volcanic area where volcanic activity is uplifted, and there is uncooled magma underneath due to the movement of the earth's crust, which will release a large amount of heat energy. Due to the concentration of heat, as long as there are porous aquifer rock formations nearby, not only will they be heated into hot water, but most of them will boil into steam, and most of them will be sulfate springs.

The second is formed by the infiltration cycle of surface water, that is, when rainwater falls to the surface, it infiltrates downwards and penetrates deep into the aquifer deep in the earth's crust to form groundwater. Groundwater is heated by geothermal heat below to become hot water, and most of the deep hot water contains gases, mainly carbon dioxide, which rush up and out of the ground when cracked.

The legendary Kunlun Mountain Unfrozen Spring is actually formed by these two reasons.

Yan Xiaoying speculated that there should have been a volcanic eruption in the crust here, and although it has now become an extinct volcano, there is still magmatic activity deep underground.

And the people who built this place don't know how to use to guide the underground magma fire up with copper pipes to refine the elixir.

Yan Xiaoying's speculation is not unfounded, the terrain here, including the karst cave stone chamber where we are located, and even the huge space inside Centipede Ridge, are very similar to the terrain formed after the volcanic eruption.

I have to say that this so-called demon general is really whimsical, and he actually uses magma fire to refine pills, which is the first time I have heard of it.

"I don't know what is in the refining ground of this black ding?" Could it really be a panacea? Like the legendary Nine Turns Golden Pill, after eating it, it will turn mortals into a divine object of the Golden Immortal. ”

While muttering, I reached out to remove the lid of the Danding, but as soon as my hand touched the body of the Ding, it was scalded and immediately retracted.

This black tripod has been burned by the earth fire all year round, and it itself is like a soldering iron, which mortal flesh cannot touch at all.

"Leave it alone, even if there is a panacea in Heiding, I'm afraid it will be taken away by the camels who came first, and it won't be our turn. The most important thing now is to find the second master and the camel, where did they go after they came here? ”

Yan Xiaoying pulled me back, away from Danding, towards the depths of the stone chamber.

Because of the weak light and the size of the place, there are some places in the stone room that we didn't see clearly.

"Smack!"

However, just a few steps away from Heiding, we suddenly heard a strange noise from Heiding.

Yan Xiaoying and I suddenly turned to look at the black ding, but we listened with bated breath, and after half a ring, we didn't hear anything.

"Probably the sound of the copper pipe that drew the magma fire up......"

"Save ...... Destiny ......"

"Knock...... Knock ......"

However, before Yan Xiaoying finished speaking, a strange sound suddenly came from inside the black ding again, as if someone was beating inside, and there was an inaudible cry for help.

This time, I heard it clearly, and the voice was indeed coming from inside the Black Ding.

"It's not good, there are people in the black ding, the smell of meat we smelled just now is not ......"
