"Boom!"
When everyone approached Shicheng, the door opened automatically.
What surprised Lu Xuan even more was that he originally thought there would be a city behind, but it turned out to be a dark passage.
The floor of this passage is paved with stone slabs, and the surrounding walls are also reinforced with stone slabs. The walls are also inlaid with some luminous stones.
Looking at the passage in front of them, Sylph, Ellie and the others looked at Lu Xuan, waiting for him to make a decision.
Lu Xuan's eyes narrowed, and his mind began to spin rapidly.
For some reason, when the passage appeared in front of him, he suddenly felt like he was being invited into a urn!
"This must be a trap!" Lu Xuan thought to himself.
Combined with the system's mission, he was almost certain that this was most likely a conspiracy against him.
However, even if he knew it was a trap, he seemed to have no other choice.
Sylph and the others searched here for a long time, but still couldn't find a way to leave the abyss.
Then, the way to leave this abyss area is probably here!
What's more, he didn't intend to just give up on the task assigned to him by the system this time.
"Let's go, there is no other choice now!" Lu Xuan said.
Then, he took the lead and walked towards the passage.
Naturally, everyone had no objections and followed Lu Xuan one after another.
The passage was very quiet, and a group of people walking in it could still hear the echo of footsteps.
The space was quite spacious, and there were more than 20 of them walking in it, and they didn't feel crowded at all.
At this time, Luo Tong subconsciously glanced at the stone on the wall as the light source of the passage, and soon showed a look of surprise.
"Lu Xuan, look at those stones, they seem to be night cloud stones!" Luo Tong said.
When Lu Xuan heard this, he also looked towards the light source on the wall.
Soon, he couldn't help but said in surprise: "I'll go, so extravagant?"
Having traveled to this world for so long, he naturally has some understanding of some of the special resources in this world.
Especially the more valuable ones!
Nocturnal stone is a rare and special mineral that can only be produced in some places with special geographical environments.
This kind of ore has a very good effect of calming the mind and recuperating the mind, and it also has the effect of restraining monsters. It is an essential material for many human weapons.
But because it is rare, it is also extremely valuable!
In layman's terms, a nocturnal stone as big as a thumb would have a market price of 100,000!
Each of the nocturnal stones embedded in the wall is as big as a football!
With such a light source, one can be seen every ten meters along the entire passage. What a luxury this is!
If we could bring these back, it would be an unimaginable wealth!
Even if they don't sell it, they can still make weapons for the students in their own martial arts school. Yan Lingxue and the others don't have weapons yet!
What's more, if this is really a trap by the man behind the scenes, then you won't get anything if you don't get it!
They took action as they said. They came to the night stone embedded in the wall and tried to dig out the night stone from the wall.
However, the material of the stones on the wall was unknown, and it took them a lot of effort to dig out the night cloud stone.
After the night cloud stone was dug out, there were no other changes in the passage, and Lu Xuan and the others could not help but breathe a sigh of relief.
The reason why we were digging so carefully just now was because we were afraid of touching any mechanism here.
Now it seems that they thought too much.
Sylph and the others couldn't help but become a little confused when they saw Lu Xuan and the others digging rocks.
Their tribe does not still have a complete economic system like the earth, so in their view, although night cloud stones are rare, they have no concept of value.
However, under Lu Xuan's instigation, they also dug some night cloud stones.
Lu Xuan believes that these may be used as start-up funds for the development of a base city after they relocate to Earth.
Although Sylph and Ellie didn't quite understand, since Lu Xuan said so, they had no choice but to do it.
Finally, the group all dug up some nocturnal stones.
For example, Luo Tong dug two of them and stuffed them into his tactical backpack. The weight was nothing to him.
The tactical backpack had limited space, and he was not a greedy person, so digging two was enough.
Sylph and the others also dug a lot, after all, they were more numerous.
Of course, the one who gained the most was Lu Xuan.
After all, he also had a space ring, and he almost filled the entire ring.
He did not plan to sell all these night cloud stones, but planned to give them to Xiao Yunyan to build new equipment for the students of the martial arts school!
In this way, a originally bright passage finally became filled with potholes on the walls.
Soon, everyone finally arrived at the end of the passage.
Passing through the passage, what came into their view was a wide stone hall with many collapsed stone pillars, which seemed to have been abandoned for a long time.
However, there are still several monsters with huge sizes and hideous and terrifying faces entrenched in the stone palace.
Their strength is all above the king level!
Among these monsters, the body is covered with tentacles and is extremely large, surrounded by other monsters!
It's an emperor-level monster!
"That's a sticky tentacle demon. It can split into countless tentacles. Each tentacle can extend nearly a kilometer. It has strong adhesive force. Once it is stuck, it is difficult to break free. It also has the ability to regenerate!" Luo Tong! said.
"In addition, the shells on their bodies are also very defensive. They are a very difficult monster to deal with. I didn't expect so many of them to appear here at once, and one of them is an emperor-level one!"
"Shall we go now?"
Ellie asked eagerly, holding the big ax in her hand.
This stone palace is very large. When Lu Xuan and the others walked in from the passage, the monsters over there didn't notice them for the time being!
Ellie seemed intent on taking the opportunity to launch an attack.
However, Lu Xuan stopped her.
The expression on his face has been weird since he entered here just now.
Because he just heard a few sounds, and then he listened carefully and it was a few monsters coming from over there.
"You said that the adults suddenly called us here. What are you planning to do?"
"How would I know? I always feel like something is going to happen!"
"Why are you talking so much nonsense? Our eldest brother is at the Beast King level. If you really want to meet a human, it's not a matter of tentacles!"
"I'm hungry and want to eat!"
"Eat, eat, eat, you know how to eat, it makes me want to eat humans too!"
…
Lu Xuan was stunned and felt shocked: "Damn it, I can actually understand it!"
A monster cannot speak human words until its strength reaches the emperor level.
But this does not mean that monsters do not have a language to communicate, and the intelligence of monsters with king-level and emperor-level strength is actually no worse than that of humans!
It's just that they can't speak human language.
But the problem is, now Lu Xuan can actually understand their communication!
