There was no cave behind the secret door, but the first thing that hit my face was a foul smell. Liu Kuo walked down the stairs and realized that this should be the underground structure of this stronghold.

Emergency lighting was installed on the wall, but the wires were just randomly pulled on both sides. There is no decoration on the walls on both sides, and the traces on them are staggered. Liu Kuo touched it with his hand, most of which were left by the blade.

It seems that in order to hide people's eyes, some cultivators have dug out this underground space with weapons.

Soon after, he found the source of the stench. There were many bones and bloody food residues scattered on the ground. Looking at the form, most of them are cattle and sheep. But there are some doubts, and Liu Kuo suspects that there are also human remains.

The miserable green emergency lights illuminated the deep underground space, and countless corpses emitted a foul smell, and the stench was terrible.

It seems that a large part of the meat in the kitchen above was delivered here. After something has been eaten, the garbage is piled up haphazardly in the passage, and no one cleans it.

Sure enough, on the rock wall next to it, there was a small black door. Liu Kuo groped carefully along the edge, and it turned out to be a spirit absorbing wood again.

Who is locked up here?

Liu Kuo opened the small door with the access control card, and was first dazzled by the dazzling white light. He hurriedly covered his eyes, leaving only a slit to prevent someone from sneaking up. After a while, his eyesight finally adjusted to the bright light, and he glanced into the strikingly bright room.

Inside, there were more than a hundred shadow claws, floating aimlessly in the air.

Bang!

Liu Kuo slammed the door shut.

Excuse me, farewell!

After making sure that the cell door was locked, Liu Kuo continued to explore downward. But there was only a straight road left, and there was nothing around. He walked for about twenty minutes, and at the end of the passage, there was only one trap.

Liu Kuo carefully pushed it away, and a burst of fresh air blew in. He poked his head out and saw a nondescript ruin, piled high with construction debris.

It was getting late, and the surroundings could not be distinguished, only the warning lights on the city wall of Wucheng in the distance could be seen.

It is about five kilometers away from Wucheng, which is already outside the city. So now it can be figured out, Lu Huaan and the others should be raising shadow claws in this secret stronghold, and most of those beef and mutton are blood food for feeding monsters.

Then they used this secret passage to enter and exit Wucheng.

After all, it is too troublesome to pass through the city gate with monsters and looted belongings, and it is easy to reveal flaws. Most of the cultivators on guard at the entrance of the city were equipped with mountain bronze swords, and if they suddenly sensed the demonic qi emitting blue light, it would be difficult to explain.

Liu Kuo returned along the same path, thinking along the way. Although there are many discoveries here, it still can't explain how Lu Huaan and the others got so many shadow claws and how they controlled these dangerous monsters.

As he passed through the cage where Shadow Claw was held again, he remembered the abnormal light inside, and his heart suddenly moved. According to Sun Xiang, Shadow Claw is afraid of light. Because in the bright light their shadows are exposed, which is their fragile body.

Did Lu Huaan and the others also discover this secret, so they used the strong light to tame this group of shadow claws?

Thinking of this, he opened the door again. But this time, because I was prepared, I was not dazzled by the bright light.

The cage was very spacious, but it was empty and empty. The source of the strong light is that the top of the room is inlaid with more than a dozen shadowless lamps used in hospitals for surgery, and the strong light illuminates every inch of the room, without dead ends.

Shadowpaw is a terrible place to live in this environment, they may be powerful and weird youkai, but now they are all floating listlessly. There is no danger of sneaking up on humans in the dark, but the big claws slowly open and close, which is a bit cute.

A shadow claw floated in front of Liu Kuo, trembling slightly, as if he wanted to communicate. Liu Kuo thought about it, and cautiously took out a piece of jerky and threw it over.

The shadow paw touched the jerky, then left disappointed. It seems that they only like fresh flesh and blood.

On the opposite side of the room, there is also a small door. Liu Kuo could see it, but he didn't dare to venture through so many monsters to check it out. Although Shadowpaw looks tame now, who can guarantee that when he reaches the middle, he will not be attacked by a group.

Then there is no escape.

Thinking left and right, he withdrew first, and then pushed a whole cart of fresh mutton from the kitchen above. Because of the fresh smell of blood, this group of shadow claws was obviously a little restless, and they floated towards Liu Kuo one after another.

He picked up two pieces of meat and threw them aside. The group of monsters was immediately attracted and flew over to nibble on them, pushing and pushing them like a flock of ducks. Liu Kuo threw out a few more pieces of meat, and finally simply pushed the cart out.

The shadow claws of the entire room gathered in a pile to grab food, and Liu Kuo took the opportunity to open the small door opposite from another direction.

It's still bright, and the overhead surgical lights are still the same. But it's not a room, it's a naturally formed cavern. The rock walls are covered with moss, and heavy water vapor seeps out of the rocks. Liu Kuo touched it, and there was a sticky feeling with.

In one corner of the cave, there is a pool of turbid water. A black crystal the size of a cart was half-submerged in the pool. It is worth noting that next to the pond water, there are many fragments of orichalite and ugin. Liu Kuo stepped forward and saw that in the turbid pool water, there were several pieces of mountain copper floating.

I don't know what kind of water this is, and the heavy orichalite can float on it.

The orichalcum ingots were in a semi-melted state, and they dissipated in the pool water, with silky bright threads spreading through the murky water, joining to strange black crystals.

Liu Kuo didn't dare to touch the pond water, so he had to observe from afar.

The huge black crystal seemed to be absorbing the metal spirit materials in the pool's water. It seems to be alive, with some strange branches growing from inside the crystal.

The tip of the twig bulges out in a large lump that appears to be a fruit. One of them seemed to be ripe when it suddenly fell off the crystal.

Liu Kuo was also worried that if it fell into the pond, it would melt like a mountain copper. Unexpectedly, this black fruit actually floated steadily in the air.

There was a soft click, and the fruit cracked on its own. It wasn't until this time that Liu Kuo recognized that this was a shadow claw!

Because of the surgical light shining on the top of his head, Liu Kuo was not worried about this shadow claw, but curiously continued to observe the crystal that gave birth to the shadow claw.

There are more than a dozen branches sticking out of it, and it seems that when they are ripe, they will turn into shadow claws like they are now.

In this way, Lu Huaan and the others should have stumbled upon this black crystal and built this secret stronghold around it. It's just that it's not clear what this crystal is, maybe Sun Xiang will know.

As he pondered, the shadow claw that had just been born slipped quietly behind him. When Liu Kuo had just raised his alertness, the shadow claws pounced.
