The Obsidian Mine, nominally a Mine, is actually no different from a city. Leaning on a huge hillside, there are layers of black stone houses built everywhere, which are now deserted, and the past glory can still be seen between the overgrown weeds and ruined walls.

At the highest point of this hillside city, there is a huge cave with a diameter of more than 30 meters, like a gate to hell, standing there as if it has not changed for hundreds of millions of years. Derpy on Impermanence's shoulder was terrified of this place, and when he saw a cave like a demon's bloody mouth, he was terrified and went straight into Impermanence's arms.

"Don't be afraid, this is the cave left by human mining and folding obsidian, there must have been a large number of automated machinery coming in and out of here back then, otherwise the cave would not have been carved so tall......" Impermanence held Derpy in one hand, standing on the edge of the black hole, and looked into the depths carefully.

The light can only penetrate a distance of three or four hundred meters here, and beyond everything is completely dark. There was a biting cold wind, which really blew directly into the marrow of people as if it had blown from hell.

"Don't you say it, this place is really evil? By the way, Derpy, I'm going to go into this cave to get something later, can you wait for me outside?"

Derpy looks back at a rocky mountain town, squeaks in fright, and gets into his impermanence jacket and can't get out. Impermanence knows that Derpy is still a young monkey after all, and his heart is still very fragile, especially when the panther is almost eaten, which hurts his young heart.

"Oh, you're just a monkey, if you're human, I'll really have to find you a psychiatrist to regulate ......"

The preparations before entering the mine have already been prepared, there is enough roast wolf meat in the backpack for three days, and there is always a stream flowing down the low-lying part of the mine because the underground water veins have been dug up in the mine, so there is no shortage of water.

On the holographic screen, a three-dimensional map is used to depict the complex passage map in the mine, and impermanence remembers every passage in his mind, and does not let go of any fork in the road. Now all communication on the giant blue star has been cut off, the terminal has no contact with the outside world, and now there is no new information on hand except for the previously copied information.

In this kind of black-eyed environment, there is no other way than to make meticulous preparations. At the bottom of the hologram, at the end of the confluence of the three corridors, there is a foggy area, where is the destination of impermanence.

Many sources show where there is a mining belt, which was abandoned halfway because the content was too scarce. But Impermanence knew that there had been a very serious accident in that area, where more than 600 miners died in three minutes, and that was the accident that abandoned the mine.

Impermanence turned off the screen and touched Derpy's head, "No matter how dangerous it is, don't run around......" Impermanence raised his head and drank two sips of water, striding towards the cave.

The obsidian mine is very large, occupying a large hillside, and the cave is located on the left side of the uppermost layer of the mine. And just as Impermanence entered the cave, on the right side of the lower level of the mine, four figures in a stone house were roasting meat on a small fire.

"It's a safe place, it's been fifteen or sixteen hours since I arrived here last night, and I haven't seen any animals, and it's as barren as a death star......," Benson sighed.

"This mining area is said to be haunted, there was a very tragic accident hundreds of years ago, more than 600 miners died in three minutes, and more than 400 subsequent injuries died, and the entire mining area was completely bankrupt after that accident...... "Odin has studied the history of the giant blue star, plus they are all from intelligence backgrounds, and they have some knowledge of some hidden history.

In front of Odin, a large holographic screen was flickering, and on it were images taken by nearly twenty spy probes, Odin hadn't seen them in days, and he was ready to scan them all while he was more relaxed.

Just as he was falling asleep, a very inconspicuous area in the lower left corner and a back suddenly flashed.

"Huh?" Odin snorted suddenly, and he subconsciously touched the area with his finger, and the image of the mouth of the obsidian mine took up the entire screen.

"Who is this? God, what the hell am I doing......" Odin was really frightened, his hair stood on end, and at this time the other three brothers also gathered around, and the eyes of the people who watched the replay were surprised and couldn't close their mouths.

"Impermanence? It's impermanence! Isn't he dead...... Or maybe he turned into a ghost and came to us for revenge...... "The Salamatan Snake is a native of the Source Fire Empire, and it is very sensitive to this kind of ghost thing.

"How can this be? Isn't impermanence entering the dark canopy? This has been confirmed by countless people? Why did it come out again?" Benson was a little mad, he really couldn't explain this strange phenomenon.

Odin's fingers dragged across the holographic screen, and the footage he hadn't had time to watch was replayed one by one, and half an hour later he discovered that Impermanence had revealed his identity in front of the three probes.

One is the place where the golden giant ape fights the coyote, and Impermanence is stealing wolf meat, and the other is a spring where Impermanence drinks with a monkey. And the third time was above their heads, at the top of the mist-shrouded hillside, at the mouth of the huge cave.

Odin jumped up at once, he grabbed the backpack beside him, pulled out piles of metal parts, and in less than ten seconds, an assault rifle was assembled, the shiny energy bullet belt was wrapped around his body, and the brass primers made a sharp sound as they collided with each other.

"Bring the weapon with you, impermanence must die, even if he is a ghost, he must die for me again......" Odin said Odin as he hung a high-explosive grenade around his waist.

The rest of the people were not ambiguous, and after a while, assault rifles, pistols, and grenades were already hanging all over their bodies. At this time, Ouyang Wan suddenly spoke, "We bring so many heavy weapons, will we be discovered by the satellites in the sky?" You know, every exam must be recorded throughout the whole process" "Don't be afraid, we walk through the stone house, try not to appear in the open space, and today is cloudy weather, after the clouds cover the entrance of the cave, we just rush in, and when we get underground, we will have nothing to fear......" As he spoke, Odin punched out the stone wall, and a big hole was punched, revealing the hall next door.

A group of four people carried the weapons secretly transported in by the Source Fire Empire, and they headed towards the cave house by house, and under the cover of countless clouds, they quickly rushed into the huge mine labyrinth.

At this time, Impermanence is experiencing a very strange underground exploration, there are some floating creatures in the dark mine cave are flashing with a faint blue light, ordinary people may not be able to see clearly, but for Impermanence Shili, these firefly-like lights are enough for him to observe the terrain.

After all, the cave was dug by man, and there were not only smooth passages for transportation machinery, but also stone steps that humans could easily climb, so there was no difficulty in walking here. At the lowest point, a stream flowed slowly, and the damp stone walls were covered with moss, but there was no sign of animals.

"There are no animals living in such a big cave? It is said that animals like to have cave protection...... Huh, Derpy, why are you shivering, isn't it cold here......" As he was talking, there was a sudden click under Impermanence's feet, and when he looked down, he saw that it was actually a pile of white bones.

Impermanence quickly shrank his feet, he thought he had stepped on human bones, but when he looked at this small skeleton, it seemed that it was either a feline or a canine corpse.

As Impermanence travels deeper into the mine, the skeletons become more and more numerous, and the types of animals become strange. And the deeper you go, the larger the scale of the skeleton. When I arrived at Zuihou Impermanence, I even saw the skeleton of a mammoth, which was quietly leaning against the rock wall, and the moss had covered part of the skeleton.

"Damn, this is really a cemetery, why are there more and more dead bodies?"

Impermanence could feel Derpy's fear, and the little monkey was afraid to look at it, his whole body curled up in Impermanence's jacket, not daring to show his head at all. Not to mention him, even Impermanence now felt a strong hair on his body, and he also found that the cold wind blowing from the ground was getting stronger and stronger.

Time passed minute by minute, and after four hours of impermanence entering the cave, he finally approached the gray mist area on the map, and this was the area where the cold wind was most ferocious, and it was also the area with the most bones.

Here, countless decayed machines lay on the ground, mixed with white bones covered the cavern, and at this time, impermanence ignited a miner's headlamp, and even summoned two bright fireballs, completely lighting up the entire cavern.

This is already the end of the mine, the huge mine with a diameter of 30 meters has stopped here, and on the surrounding stone walls, there are some black rocks that actually reflect a faint fluorescent green under the light, which is the famous folding obsidian in the universe.

Just as Impermanence was carefully observing the terrain, he suddenly found that in the corner at the end of the mine, there was a hole more than a man high, and that was the source of the cold wind, and the whirring cold wind came out of nowhere like a ghost crying.

"It's so cold, this should be the ghost gate that Lord Thief Tuo said, but why is the caretaker he said nowhere to be seen?" Before Impermanence could breathe a sigh of relief, a cold light suddenly flew out of the oncoming cold wind, and the sound of swishing through the air was like a feather arrow shot by the dark elves.

"Here ......" impermanence finger subconsciously clicked on the terminal, the identification software began to work, and the wireless signal filled the entire mine, and began to establish an active connection with the attacker.

It was only at this time that Impermanence saw clearly that it was thousands of magic shuttles, commonly known as ghost darts, that attacked him.

This fusiform dart has an unusually sharp serrated drill bit and is equipped with a very advanced miniature anti-gravity engine that can hover in mid-air and shoot at high speeds. Those serrated bits could easily penetrate sturdy armor, and even war armor could be destroyed by him if he had time.

It is said that in this universe, the ghost darts produced by the bayonet should be the best quality and most powerful, but Impermanence knows that the shuttle he is using today is definitely more advanced than the one produced by Tong Yan, because Master Thief Tuo said that these guards have existed for thousands of years. The fact that the magic shuttle produced thousands of years ago can still be used today is telling.

"Biedong hand, I'm my own person......" Impermanence himself didn't realize it, and the voice in his mouth even trembled a little. But this is also a helpless thing, and if the thief is here, surrounded by thousands of magic shuttles, he will also be afraid.
