Overlord: Start from the Goblin Lair.

"Okay, now we know why those murals and words were erased," the goblin hunter crossed his shoulders, "this guy can pass through walls like a real ghost, and at the same time he can do odd jobs like an ordinary servant."

"How convenient..." Sylvia murmured. "The Yeshih hounds could never do these things - it can definitely do more than just wipe the wall."

So... everyone's attention naturally turned back to the pile of bones - if there had always been a group of arcane servants like this one, and even judging from their numbering, they might have been taking care of it, then why did this corpse die here?

Ron's mind flashed through various sci-fi movies, such as AI mutiny and self-awareness awakening leading to human extinction. But a work of art is a work of art after all. The fact that creatures like arcane servants can also have the characteristics of spirits is the result of the creator's great thought. They absolutely cannot be compatible with a set of advanced thinking patterns. If the creator can do this, then he or they will not be destroyed by their own creations.

Unlike the humans who create robots in those movies, these wizards are all talented in both literature and martial arts and have unique skills.

"Maybe you should clean this up," Ron said calmly to the 2308, "Or do you have a model specifically for cleaning floors and repairing equipment?"

2308 heard what Ron said, but it did not stop the work in its hands. The arcane light on its surface slowly flickered: "Sorry, Wanderer, we cannot understand your instructions. No similar items were detected in the 'Spiritual Service' working directory."

Sera stared, "What does it mean?"

"It only acts according to fixed instructions," Ron nodded slightly at the barbarian, "The setting of their spirit is really convenient, otherwise you would not be able to break open the door with one punch."

Sera was still confused: "Huh?"

"If they were physical entities," Ivy pointed at the door behind them, "they would be blocked by the door when they followed instructions, and then all crowded behind the door - do you think you could kill more than 2,000 of these physical entities with one punch?"

The chief lady thought about it seriously, shook her head and said, "That's impossible - there's not enough space in the corridor."

It turns out that she has actually started to think about the feasibility of this!
Ron patted his forehead to get his thoughts back: "Two-three-eight, you are the 'spiritual servant', right?"

"Yes, Drifter."

"Then let's search, what projects are you responsible for?"

2308 paused for a moment before resuming his actions: "Project one, keep the walls clean; Project two, receive visitors and returning wanderers. Project search completed."

Now it was Ron's turn to be dumbfounded: Are these two even close to each other?!
"It seems that we can't find any more clues from it," Victoria frowned, "Perhaps finding the rule maker behind these 'spiritual services' is the key to solving the problem."

According to her thinking, they should accept the guidance of the other party and then act accordingly. But now it seems that this arcane servant might be even more confused than them.

"Okay, keep working," Ron nodded. "Let's go down here - Driver, keep exploring."

The goblin raised his head and said, "I don't think it's necessary. Although this place is dusty, there are still people moving around. Who would bury a trap in their own home?" "Isn't this the nest where you and Kalade used to live?" Ron's words choked back the goblin who was deeply "corrupted" by the civilized world.

The ranger walked to the front again obediently, knocking the two short blades in his hands against the surrounding walls and floor tiles from time to time. He did this not only to confirm whether there were any traps around, but also to test whether the spirit servants had some kind of defense mechanism - after all, in their work, keeping the walls clean was even more important than receiving visitors.

However, when the walls on both sides were dirty, the crowd did not encounter any hostility or obstruction except for some spirit servants who came out of the walls one after another and started cleaning. It seemed that those spirit servants were really just responsible for cleaning and did not care about anything else.

Instead, the goblin hunters checked out many traps that were either inoperative or still operational.

There was another light "click" sound, and Driver with a serious expression slowly pulled out the knife from the gap between the bricks. With his other hand, he quickly grabbed a piece of rusty metal that was only half the thickness of a gold coin and pulled it out. A crossbow with only half a wooden pole left fell out of the wall with a clang.

"It's rotten, but not completely rotten." Driver stretched out two fingers and dug into the hole in the wall, but there was nothing but some mud-like paste. "It's similar to the previous ones. These are crude traps set a long time ago. Whoever set them up was definitely not the one who controlled those spirit servants."

He smeared the mud on the wall, and sure enough, another spirit servant came to clean it up. Ron couldn't help but look back at the road he came from. There was a trap marked or exposed by Driver almost every three or five steps in the corridor. If he went back ten minutes, the number of traps was less than half.

And there wasn't even a trap at the door.

"It's weird..."

"Yes, it's really strange," Driver clapped his hands and said, "No wonder those spirit servants are responsible for leading the way even though there is only one corridor. If there is no master like me, everyone who comes here will suffer."

"Do what you can," Sylvia rolled her eyes. "Almost 80% of these are broken traps, and the remaining half are like this one and can't function completely."

"But if you get one, you'll be in trouble," Driver laughed. "This is no joke. Even if these don't take full effect, can you guarantee that you'll be that lucky?"

This is actually a question of probability, but when it comes to life, no one wants to know what comes before the percent sign - as long as it's not 0 or 100.

Who hasn’t had bad luck sometimes?

Ron subconsciously grabbed the "lucky gold coin" in his pocket. He couldn't feel any blessing power, he just wanted to seek peace of mind.

The cold coins became warm, and his brain seemed to have rested: "Drivedo, you know more about this. What do you think is the reason why these traps are distributed like this? Generally speaking, we all hope to keep intruders out, right?"

But whether it is at the bottom of the rift or behind the gate, there are large areas of empty space. In fact, the deeper you go, the more traps there are. (End of this chapter)
