I'm a monster in Demon King's Castle

"Got it? How do we do it?" Before leaving, Lee Read put on the Van Helsing skin, patted his belly, and asked Lulu and Feifei.

"Got it!" Lulu saluted Lee Read.

"If there are intruders, leave the lone ones to the instructor and his skeleton legion!" Feifei pointed to Galarick, who was sharpening his sword nearby.

"For the swarms, lure them into the Bloody Corridor and crush them into mincemeat!" Lulu pointed to the floor directly below the cave.

"If any slip through the net, use Piggy's Chaos Cuisine and mobilize the entire army! Total cleanup!" Feifei stretched out his arm and pulled out a large pig bone from the corner—it was Piggy's "Golden Oil Pig Bone," which was very stable and had some self-healing ability.

"At this time, we can use the electric towers! Protect the Evil Horn Beasts, one by one! Fry the intruders' brains!" Lulu pointed to the King's Electric Horn embedded in the wall; the electrified horn crackled with electricity.

Lee Read had tested it, and the arrangement of the electric horns had tried to cover every corner as much as possible. Even the small kitchen had two plugged in, which Piggy often used to experiment with electric shock cuisine, trying to recreate Dad's electric slug.

But there was only electric shock, no slug.

"If that still doesn't work, retreat with the entire army and tell the Lord of Brains to press this!" As she spoke, Lulu touched a bone card floating next to the altar.

That was the communication equipment Lee Read left for the left and right guardians.

"Call Brother back and kill the intruders!" Lulu and Feifei roared, wishing they could call Budibo Ge to try it out now.

That's right, once the skeleton legion, the Bloody Corridor, and the electric towers can't handle it… Lee Read's plan, of course, was to have Budibo Ge borrow the power of the library's authority to mobilize the Staff of Deception to ask him for help.

At that time, Lee Read would return to the library as soon as possible to personally carry out the elimination.

However, judging from the library's current record, adventurers below the seventh rank, or demons who have not yet reached the high-level demon rank, have almost no way to break through the bone house reception room placed at the entrance of the library, nor can they withstand the electric towers.

In other words, most of the adventurers who invade the library are here for the "Brain Spirit Pituitary Gland," and will not make corresponding preparations for the electric towers, skeleton legion, or even Mini Minnie warriors.

As long as he is low-key enough, there will be no mistakes, and Lee Read will have plenty of time to explore outside, without worrying about the library being in danger.

"Then Brother is leaving, bringing back a craftsman for you…" Lee Read touched the heads of the two little ones, then nodded to Galarick. His figure gradually faded and disappeared into the upper cave.

When leaving, he accidentally tripped over a protruding cable. Lee Read removed the color-changing effect of the photon pigment, turned around, and told Lulu and Feifei: "Tell the Mini Minnies! Study hard! Don't play with the cables anymore! It's very dangerous!"

Lulu and Feifei were quite aggrieved—it was clear that a Brain Spirit was very interested in electric shocks and accidentally pulled it out when passing by.

"Understood!" Lulu and Feifei decided to convey Lee Read's will and told him to go to the underground city with peace of mind. "Brother, have a good trip!"

Lee Read heard the two little ones' inner voices and thought that the library might have another Brain Spirit named "Dian Dian" in the future.

…

The underground city is a maze with no exit, mainly the activity area of dark elves and dwarves, and also a huge garbage dump under the Demon King's city.

Such as skeletons, corpse collectors, demon bats, freaks, and even evil horn beasts will haunt the underground city, enjoying the mud and death.

And because there are dark elves, in this filthy underground, countless strange things that can't even be named have been crossbred. Lee Read is not even sure whether they are demons or mysterious creatures.

No, a short freak with a beard is walking past Lee Read. Judging from its form, it should be a headless freak, but its chest hair is tied into a knot and it is short, so it should have some dwarf blood.

The big Van Helsing is not abrupt here at all. Lee Read casually picked up some rotten cloth from the corpses at the base of the underground city wall and wrapped it around himself, perfectly blending into the environment.

As for the headless freak and the dwarf hybrid, they seem to be a little interested in Lee Read, perhaps because of the kinship that arises on the freak puzzle—he slowly walked around Lee Read, his facial features on his chest facing Lee Read, the quiet on his pectoral muscles looked up and down, and then moved back to maintain basic vigilance.

Lee Read didn't let the headless freak run far. After the Demon Illustrated Handbook analyzed it, it included the 884th demon, the Headless Freak.

【Is he the child of humans and freaks? Why is he following me?】

Hearing the Headless Freak's inner voice, Lee Read felt confident and waved to him: "Hello?"

【Hello what? Does he think I'm good and want to eat me?】

The Headless Freak faced the wall and moved horizontally to the next passage.

At present, the two are in a square room—the entire underground city is almost entirely composed of square rooms and straight passages. Each room corresponds to four passages, which is an endless and endlessly growing maze.

Perhaps no one except the Lord of Authority of the Underground City can know the whole picture here.

Lee Read "swam" in from the ceiling by drilling through the soil, and also drilled through the earthen wall here. He didn't find any mechanism, but felt that the earth element here was very active, different from the one in the library.

Maybe this is why the underground city can continue to expand.

"Do you know dwarves?" Seeing the Headless Freak's inner drama was so rich, Lee Read thought it was a good time to ask about the location of Borgny Copper Spoon, because… he was lost.

The underground city is indeed difficult to navigate.

【My mother is a dwarf…】

The Headless Freak still stared at Lee Read warily, without saying a word.

"Are you a dwarf? Where do dwarves live? Where do your relatives live? Do you know the Copper Clan?" Before coming, Lee Read had compared the approximate location of Borgny Copper Spoon with Galarick, and learned that his workshop was located on the edge of the Copper Clan's gathering place, named "Copper Spoon Handywork."

Originally, Lee Read had dived down according to the location marked by Galarick, but he didn't expect to get lost immediately after arriving in the underground city, and didn't land in the Copper Clan's gathering place as Galarick said.

Perhaps the times are different, and the underground city has undergone new changes. Lee Read had to search again.

【I am from the Copper Clan… Not only wants to eat me, but also wants to eat my whole family?】

"What do you want to do?"

Hearing this sentence, the hairs on the back of the Headless Freak's neck stood on end, and his vigilance was raised to the highest level; at the same time, fine sand began to fall from his body, and small particles flowed out of his facial features.

Lee Read knew that this was the Headless Freak's ability "Sand Hell." When he was first promoted, Yingying had demonstrated it with the Freak Puzzle.

"You are from the Copper Clan? Very good…" Although Lee Read didn't care about the fine sand that the Headless Freak was shaking off, he also pulled the distance a little further—after the first successful promotion, he was already able to deal with a team of freaks attacking together. Now, when Lee Read saw this familiar technique again, he only felt like it was child's play.

However, the Headless Freak couldn't drop anything good. Now Lee Read just wanted to pry information out of his head.

"Do you know Borgny Copper Spoon?" Lee Read asked, leaning against the wall.

【Borgny Copper Spoon? Is he looking for Copper Spoon?】

The facial features on the Headless Freak's chest suddenly all squeezed together.

【Copper Spoon Handywork… should have been torn down, right?】

【Borgny Copper Spoon… should be dead, right?】

【The dark elf boss and the copper spoon leader have disliked him for a long time. These days… they are going to pry open his workshop and share the spoils…】
