Zhang Xiaoshuai started to explain this topic in a stern manner, showing off his "profound" knowledge according to the script: "More than forty years ago, geologists accidentally discovered an underground cave while drilling for natural gas. They used all detection methods to
equipment, it is also impossible to detect the depth of the cave. Because the cave
It was filled with flammable gas and no one dared to go down, so the geologists lit it on fire and prepared to go down to explore after the flames burned out. Who knew that after the gas in the cave was ignited, it burned for a long time and has not been extinguished to this day. It looks like
It is the sea of fire, so it is called the Gate of Hell."
"Boss, don't you want to take a look? What's so interesting here? We still have to steal diamonds!" Shang Yang said quickly.
"Even if there are natural gas mines connected underground, how much natural gas can continue to burn for decades?" Ye Xuan asked.
"This... I have to do the math." Zhang Xiaoshuai started looking for Du Niang again.
"Don't forget it."
Ye Xuan rolled his eyes and said: "What I want to say is that it may not be as simple as natural gas. I always feel that there is something wrong."
Gongsun Ningfeng couldn't help but smile bitterly and said, "Ye Xuan, when did you become interested in this kind of thing?"
"No, this time is different, I always feel..."
When he saw the flames just now, he had an indescribable feeling, otherwise he wouldn't have asked the pilot to stop: "I don't know why, but I feel terrified, as if there is something bad here."
If Lucia said this, everyone would definitely be very nervous. People with powers of prophecy can sense very accurately, but Ye Xuan does not have prophecy. What could he foresee?
"Do you think you are a prophet?" Zhang Xiaoshuai mocked him angrily.
"I want to go down and take a look. It will be quick. Anyway, it won't delay the business. You can just wait for me here."
After speaking, Ye Xuan immediately activated the space transfer. In the blink of an eye, he was already standing on the edge of the huge cave from an altitude of 10,000 meters to the ground.
Huhuhu...
Red flames mixed with light blue rose dozens of meters from the cave. The entrance to the cave was roughly circular, with a diameter of an astonishing one hundred meters.
A cave with a diameter of 100 meters and a flame that has been burning for decades. Ye Xuan absolutely does not believe that what kind of natural gas mine has so much natural gas that can be used for such exaggerated consumption.
reason?
Right below!
In fact, even he himself didn't know why. Even though he didn't have the ability to predict, he felt a sense of danger when he passed by here.
This feeling is not fleeting, but becomes clearer as he gets closer to the crypt. Now he can even feel that this danger is not immediate. In other words, it does not mean that he will be in danger if he goes down now.
, but the crisis here will break out at some point in the future.
If it was just random thoughts, of course he wouldn't care, but that feeling that could only be imagined but not expressed in words was real.
He also felt strange, but he couldn't help but believe it because it really existed.
Although the burning temperature of natural gas is relatively high, especially for such large-scale combustion, the maximum temperature is even nearly 2,000 degrees Celsius, but it is not enough to pose a threat to high-level ancient warriors and those with defensive powers.
Sudden!
Just when Ye Xuan formed a light blade and was about to cross the void, several sword lights fell from the sky, and it turned out to be Zhang Xiaoshuai and others.
"What are you doing here?" Ye Xuan asked.
"Something's wrong!"
Zhang Xiaoshuai's face was ugly, and he said: "Brother Song used the instruments on Yinyou just now to try to detect the data in the cave, but even those high-end equipment couldn't detect it. He was interfered by some inexplicable energy. This energy has nothing to do with it.
What we know about interference is completely different."
"That is to say... what I feel is probably true..." Ye Xuan became a little nervous.
"Let's go! Let's go down together!"
"no!"
Grabbing Zhang Xiaoshuai who was about to go with him, Ye Xuan hurriedly said: "It's really because there is a problem that you can't go down. I can do it alone."
Zhang Xiaoshuai was stunned for a moment, then said displeasedly: "Holy crap! Are we still brothers?"
At this time, Gongsun Ningfeng also grabbed him and said seriously: "Ye Xuan is right, it has nothing to do with whether we are brothers or not. The key point is that the strength gap between us and him is too big. I don't believe that there is anyone on earth who can threaten him."
thing, besides, doesn’t he still have more than one million energy points? What about you? If there is really any danger and he can leave safely, if you go, you are seeking death, or you are just dragging him down."
"Am I a burden?"
With a helpless smile, Zhang Xiaoshuai had to admit the fact that there was a huge gap in strength between the two sides, and said instead: "Okay, be careful yourself, and run away immediately if there is any problem. If you don't come out within half an hour, no matter what, I will
Everyone, go down and don’t stop anyone."
Ye Xuan nodded, feeling a layer of cold air lingering all over his body, and his figure turned into a stream of light and threw himself down.
flame!
high temperature!
When he entered the cave for tens of meters, he immediately realized a problem: Why is there still a flame here? Natural gas bursts out from the cave entrance and burns. That is because there is oxygen outside. It should be impossible to ignite inside the cave. There is only natural gas here and there is no fire.
No oxygen.
But the fact is that as he continued to go deeper, the entire cave was filled with flames, just like purgatory in the movie.
The deeper he dived, the more frightened he felt. This was no longer a matter of natural gas still burning without oxygen.
At this moment, he estimated that the distance he had penetrated was at least two thousand meters!
Although the cave is slightly narrower here, it is still not at the end. In addition, the mental power is suppressed by a certain energy and has been shortened dozens of times. With his current late-level X-level realm, the distance explored by the mental power is definitely dozens
kilometers, but now there are only about a pitiful kilometer left.
As it goes deeper and deeper, the containment of that weird energy on mental power becomes stronger, and the scope of mental power exploration continues to shrink.
Originally there was only a layer of cold air to resist the flames, but now he used all his abilities to form layers of defense walls outside his body.
The most outrageous thing is that as the depth continues, not only is the mental power restrained and strengthened, but the temperature of the flames is also getting higher and higher.
When the depth of the cave reached about fifteen kilometers and the diameter of the cave was only about forty meters, the color of the flames changed to a pure deep blue.
According to preliminary estimates, the temperature is at least over 5,000 degrees!
Eighteen kilometers!
Twenty kilometers!
Damn it!
The crust in some relatively unstable areas is only 10 to 20 kilometers at its thinnest. Shouldn't this cave lead all the way to the mantle beneath the crust?
The junction of the earth's crust and mantle is the legendary asthenosphere, where there is only one thing - magma!
Bang!
Just when Ye Xuan felt a little guilty, his feet fell softly to the ground. Fortunately, the bottom of the cave was not connected to the asthenosphere. It was still a world of flames, and the temperature had risen to over 8,000 degrees, but there was ice control
The cold air blocked by the supernatural power, and the high temperature and scorching heat had no effect on Ye Xuan.
Thanks to the flames all around, the surroundings can be seen clearly through the light of the fire.
Otherwise, twenty kilometers deep into the earth, even if the vision of a person with superpowers is far better than that of ordinary people, the vision will be affected without any light source.
The bottom of the cave is about 234 meters in diameter, irregularly round, and does not seem to have many artificial traces.
But Ye Xuan noticed a problem!
These flames are not formed by the burning of natural gas. Even if there is natural gas at the entrance of the cave, it is only used to hide the fire from others.
The source of the flame was at the bottom of the cave. After being suppressed to the point where only his mental power was left, and the detection distance was less than three hundred meters, he noticed that the bottom seemed to be uneven, and the surface of the rock that had turned into a dark brown after years of melting was actually covered with
There are countless densely packed holes.
To put it bluntly, those flames erupted from small holes, but how could there be such dense holes in normal rocks with such uniform density?
The unknown sense of crisis worried him, and it also made him want to uncover and nip this future crisis in the cradle as much as possible.
boom!
The mace struck hard at the rock made of unknown material at his feet.
Obviously, ordinary rocks cannot exist in a solid state at a high temperature of 8,000 degrees, and have long since turned into flowing lava.
Accompanied by a loud noise, a large hole was opened in the rock beneath the feet, and then overwhelming flames roared from below.
really!
Ye Xuan's eyes lit up. It was exactly as he imagined. The source of the flames was not natural gas at all. There was another article below the bottom of the cave.
Carefully filling his body with supernatural powers and infuriating energy, if it weren't for not blocking his sight, he would have even put on super-solid armor. After making sure that his defense had been raised to the limit, he carefully stepped on the light blade and followed the quilt.
The big hole opened by the mace continued to penetrate deeper.
What happened next completely shocked him.
It is no longer a cave passage that continues to deepen, nor is it a small space of more than twenty meters directly. The traces of key artificial excavations here have become much more obvious than in the cave.
This is a large space. Although there are not many furnishings and displays, there are human traces everywhere.
Corresponding to the cave separated by a layer of rock, countless long sharp needles pierce into the rock. Through mental observation, you will find that these long needles are hollow. Every hundreds of dense long needles, there will be
Connected to a pipe as thick as a wrist, countless pipes penetrate deeper into the ground. How can Ye Xuan not understand after seeing these?
The so-called flame is actually connected to the magma layer through a pipeline, and the high temperature of the magma layer is converted through pipeline transmission and some kind of equipment.
Then the long needle is used to prick the rock at the bottom of the blood cave, and countless small holes invisible to the naked eye are opened on the rock corresponding to the position of the long needle.
In this way, if you don't have the mental power to observe carefully, it is impossible to find any clues, and naturally you will not think that the flames are actually spraying out from the rock.
The area corresponding to the bottom of the cave is only a small part of this space.
This place is much wider than the cave with a diameter of more than 20 meters at the bottom. It is also circular overall. However, in order to prevent people from discovering the traces of artificial excavation, the circular shape of the cave is not very regular. The shape here is extremely regular, and the diameter is even more
