This is not a very big space!
There are many precision instruments operating in the space, with various meters on these instruments, and some sparkling bubbles continuously spewing from glass tubes.
And in the center of these instruments stands a tall machine!
At first glance, this machine seems to be a natural formation of metal, with no seams or screws visible at all, giving it a sci-fi feel that is currently difficult for many Earthly worlds to achieve.
Strangely enough, this machine is almost identical to the one in the underground world of China!
Several men and women in protective suits are busy near this machine.
They look at this machine, with countless tubes extending into the ground from the machine, and it's unclear where they lead.
One of the tubes is cut open, and then another tube is pulled out from inside, which is directly connected to the instruments operated by these researchers, and various data are constantly fluctuating!
These researchers don't know what they're studying and appear very busy!
Meanwhile, seven or eight kilometers away, on the peak of Mount Fuji.
Jia Yan drilled into the interior of a 3,000-meter-high cave!
The cave has a high temperature, and as Jia Yan delved deeper, he didn't feel much cold at all. His body temperature gradually rose, and even his agility gradually returned to its normal level.
This place may have been explored by humans before, but Jia Yan continued to crawl forward.
The cave is mostly composed of volcanic rocks, dark black stones with obvious traces of high-temperature burning. Jia Yan scrutinized these stones as he crawled forward. His compound eyes constantly flickered with a strange light!
Although the cave entrance is narrow, after crawling for some distance, the space becomes slightly larger, and as Jia Yan moves forward, he no longer feels hindered, able to crawl more smoothly!
"The temperature is getting higher and higher. Looking at the terrain, this space is also continuously descending. I'm afraid the cave leads underground."
Jia Yan is in a continuous downward slope in the cave. The gleam in his compound eyes intensifies, and he continues to move his six feet!
In this cave, the initial traces of human presence become increasingly sparse, but the temperature around him gets higher and higher.
Jia Yan sees that caves from all sides begin to connect, obviously this is no longer just one cave, but several caves merging into one.
Of course, the typical end of a volcanic cave is usually a dead end after a short distance, after all, these caves are formed by volcanic eruptions, with caves formed by the ejection of volcanic rocks in asymmetric crevices. These caves are not like those formed by external water flow, which tend to be longer. These volcanic caves are generally short-lived and often become dead ends after a short distance!
However, the cave Jia Yan descended into seems a bit different!
This cave continues straight ahead, and the temperature keeps rising along the way. By the time Jia Yan realizes it, the surrounding temperature is not low at all, but extremely high!
He entered the cave just to investigate, considering it as having no specific plan, just finding something that might be feasible to do!
But he really didn't expect to come all the way down to such a deep place!
The underground is very deep and hot.
When Jia Yan comes to a relatively open area to rest, there's no more road ahead!
The ground is covered with material melted from the surface, which has solidified. This material is absolutely extraordinary!
It's the substance hardened from magma!
"This place used to be magma!" Jia Yan sees these things, and then, through the infrared function of his compound eyes, he finds that their current temperature is also not low, probably above seventy to eighty degrees!
It's estimated that if he goes further down, the volcanic magma will be not far away.
Jia Yan suddenly feels terrified. Volcanoes are not to be trifled with. If it erupts now, he won't even have a place to run!
"There's no road ahead. Should I go back like this?"
Jia Yan estimates that he has descended more than four thousand meters, which means that this place is no longer above sea level, but below sea level!
Forget about sea level, just talking about the distance he has descended, the depth of this place exceeds the factory in the underground world of China!
The underground world is only a few kilometers deep, but here he has descended more than four thousand meters, which is four kilometers!
It's a very terrifying place.
The surrounding air temperature is extremely high, probably over forty degrees. Even though he hasn't felt much discomfort, it might not be the same for humans!
And Jia Yan, through his mutated 'respiratory organs', senses that the air here is also unusual. Although the oxygen content is not low, it is definitely mixed with unidentified toxic substances. He may not have felt much discomfort, but for humans, it's hard to say!
So either this place has never been explored by humans, or humans have been here but it's not a place they would frequent!
The entire flat lava area is roughly around three hundred square meters, but scattered throughout are some rocks that seem to have fallen from the ceiling of the cave!
Jia Yan thought for a moment, then lightly placed one of his front feet on the nearby molten lava ground.
The temperature, around sixty or seventy degrees Celsius, was extremely hot!
Despite being enveloped by the solidifying substance, the long-legged creature felt a slight sense of relief while stepping on the warm ground!
Compared to insulating against the cold, the solidifying substance seemed to provide even better insulation against high temperatures!
Or perhaps, contrary to fearing low temperatures, Jia Yan's body had an unexpectedly high tolerance for high temperatures, surprising indeed!
Jia Yan's feet on the ground did not make him feel uncomfortable at all.
His compound eyes gleamed.
Then Jia Yan continued walking forward, stepping on the ground.
He was surveying this flat lava surface!
There were many large rocks on the ground, and some places were dead ends that Jia Yan needed to observe carefully for any clues in the crevices.
Although it's certain that the large mechanical device under the factory of the country of Xia couldn't be hidden in such small spaces, who knows if this "divine object" of the Wa country is also so huge? If it's just a small thing, then he should be extra cautious!
Although Jia Yan didn't have much hope for this place, since he had come down here, he should at least make a little effort!
There were many narrow passages, and Jia Yan began searching for clues on the ground made of molten lava rocks.
However, there was no harvest. With an area of over three hundred square meters, it's not exactly large, but it's not small either. Jia Yan spent twenty minutes carefully examining almost every corner, and even in some places where he couldn't climb, he spread his wings and flew over to inspect.
After such a long time, there was no harvest at all.
Jia Yan couldn't help but feel a little discouraged!
"There's still one last part left, and it's also the most dead-end part. I guess if it weren't for my ability to fly, humans wouldn't be able to get through no matter what. Unless they can also fly over!"
Looking at a corner blocked by several large pieces of molten lava, there was a strong smell of sulfur rising from below!
To be honest, Jia Yan felt that the place might directly lead to magma, which was quite terrifying.
But since there was only this one place left, he couldn't just avoid exploring it because of fear, right?
Even if there was magma, it wouldn't erupt immediately. After all, this place had been quiet for hundreds of years. If it happened to erupt within the short period of time Jia Yan came down here, his luck would be unbelievable. Even buying a lottery ticket wouldn't be as unlikely as that!
After looking at that area, Jia Yan estimated the way to enter, and then spread his wings!
Relative to his wingspan, it wasn't that easy to get into that place.
Buzzing!
Jia Yan flapped his wings.
The sound was very clear in the bottom of the cave!
Jia Yan flew up.
Flapping his wings cautiously to avoid the molten lava.
After flying over one, two huge pieces of molten lava, the small corner at the bottom of the cave finally appeared completely in front of Jia Yan!
"What is this?"
The strange gleam in Jia Yan's compound eyes became even brighter!
Everything in front of him was within Jia Yan's expectations, but also beyond his expectations!
It was a small pool with a width of only about fifty centimeters.
There was no water in the pool.
Instead, there was a glowing red molten liquid!
Magma!
These liquids kept churning, and when they came into contact with the air, they quickly turned into black substance. But when this substance sank into the magma, it immediately turned back into bright red magma.
This was a magma pool!
The temperature in the entire magma pool was extremely high.
Jia Yan could feel the temperature filling the sky even when he was flying above, making his whole body and wings warm.
The air here was probably around forty or fifty degrees Celsius, and if it got any lower, it would probably reach seventy or eighty degrees or even higher!
As for the temperature inside the magma, let alone, this dark red magma should be at least over 600 degrees Celsius!
The parts that were churning might reach over a thousand degrees, which was extremely terrifying!
Jia Yan didn't dare to descend too much. Although the temperature in the air couldn't harm him, if he accidentally fell into the magma pool, even with his confidence in his temperature resistance, he wouldn't believe that he could survive!
"The appearance of magma was within my expectations, but also beyond them! But the appearance of another thing really surprised me. However, it's probably not strange for it to appear here. It's just that I never thought I would see it here."
"Maybe I should say it's expected but unexpected!"
Thinking of this, Jia Yan shifted his gaze to something near the magma.
To see such a thing here!
That would prove something...
The compound eyes of Jia Yan flickered with brilliance.
