I'm a monster in Demon King's Castle

The first electric tower test firing experiment was actually very crude in Li Yue's mind.

If the cable can transmit the electricity from the Thunder Pool and transfer it to the King's Electric Horn embedded in the wall, then how can the King's Electric Horn determine friend from foe... that is the most important problem to solve.

Li Yue pondered for a long time but couldn't find any scientific solution, so he remembered the old Evil Horned Beast he brought back from the Forbidden Forest—when they first met, the old Evil Horned Beast shocked him with electricity, and when he was inside the battery, the three Evil Horned Beast guards directly shot electric arcs at him. Did that mean that Evil Horned Beasts have this ability?

So, after signing the contract, Li Yue had the old Evil Horned Beast electrocute itself and then fire electric arcs at a fixed position, successfully charring several walls covered with bone spurs.

This led to the real test firing experiment, and the experimental target... was a Hero.

In recent days, there have been more and more Heroes in the Demon King's City, so Li Yue sent Budi Boge out to investigate, hoping to lure a guinea pig over; it can be said that the heavens reward those who work hard, just as the audience took their seats and the cable was energized, Budi Boge successfully fished one over.

Holy light approached outside the door, and the inner side of the bone room reception room was also full of onlookers...

For some reason, the old Evil Horned Beast was a little uneasy.

It never thought that one day it could control the lightning of the Thunder Pool, and there was some anticipation mixed with the unease.

When the holy light illuminated the bone room reception room, like the rising sun, a Hero jumped in and entered the library; and Li Yue directly tore down the ceiling, completely blocking the demons behind him, waiting for the holy light to dissipate.

As the holy light dissipated and the bone wall receded, the Hero saw countless demons behind the bone throne.

There were solemn-looking skeleton soldiers, curious Mini Minis, and brain spirits rubbing their brains together, all looking at the Hero like they were looking at an animal, with the Little Sweet Potatoes whispering to each other.

And beside the throne, facing the Hero, was an Evil Horned Beast, its horns a little withered, but still staring with its front legs, as if about to attack.

"What is all this?" The Hero couldn't understand what was happening in front of him, and then his vision was covered by a flash of lightning.

Snap!

The Hero's armor instantly melted, intertwined with charred flesh, becoming a lump of meat on the ground.

Like electrocuting a mosquito.

It was so fast that Li Yue didn't even remember what he looked like.

The scene was silent.

"Was I too hasty?" The old Evil Horned Beast felt a little embarrassed, unsure if it had done the right thing, or if it had completed the experiment.

"No, you did very well." Li Yue sensed the puddle of meat on the ground, his heart surging.

From now on, the library began to move towards the electric age, no longer completely relying on the magic power allocated by the Demon King.

In this way, Li Yue could have more time to hunt demons outside to collect materials, find a way to unseat Oogie Boogie, without always worrying too much about the safety of the library.

And this was the limit of what Li Yue could do at the moment.

If he wanted to evolve the library further, he would need a professional like Borgny Copper Spoon to help Li Yue build the Thunder Pool into a truly safe and operational power system; or find the Kingston family's relic, contact Jessie, and buy more magic cannons or magic cannon parts from her to assemble himself.

Perhaps inspiration for the power system could also be obtained from Jessie—Li Yue had already decided that after capturing the anticipated Borgny Copper Spoon from the underground city, he would go to the arena to find the mirror again.

So many days had passed, and more Heroes had entered the Demon King City, so the limelight should have passed.

By the way, he could also ask Copper Spoon what materials he needed during his next trip to the arena, and pay more attention—at least the Eye Demon's monitoring system was already very useful, and if it could be replicated in the library, a control room could be built in the upper cave, so the Mini Minis and brain spirits wouldn't need to directly contact the invaders, just flick a switch.

Thinking this, Li Yue glanced at Galarick, the library's garrison commander also understood, and separately arranged a team of skeleton soldiers to guard the safety of the old Evil Horned Beast—this was an important contributor to the electric tower's ability to function, and also a candidate to be the leader of more Evil Horned Beasts in the library in the future, so it needed to be well protected.

When Li Yue met Lulu's gaze and nodded slightly to her, his dear sister jumped up high and shouted to the entire library: "I declare! The first energized test firing of the library's electric tower is a complete success!"

Lulu and Feifei jumped very high, and the Mini Minis clapped their hands crackling.

The old Evil Horned Beast received the affirmation of the library's demons and never felt so powerful, and wanted to do more, so it continuously released lightning, striking the empty space in the center of the bone room reception room.

Bright electric lights began to light up constantly beside the throne, as if celebrating the library's technological progress.

And the skeleton soldiers on the wall were silent for a while, then suddenly rushed into the electric light, dancing under the electric light, and bouncing next to the Hero's corpse.

Li Yue almost forgot that skeletons had this hobby, and looking back at Galarick's itchy feet, decided to let them celebrate freely first, and tomorrow let the old Evil Horned Beast take the King's Electric Horn to collect its kind, to satisfy its desire to be a stud.

Of course, for the first time, Li Yue only planned to have it bring back three or four female Evil Horned Beasts for backup, no need to bring a whole bunch.

Because Li Yue hadn't arranged supporting living environments for them in the library, even the food was just hard lumps of meat and side dishes sent by the demon kitchen, plus some self-healing bones.

As for the trip to the underground city, Li Yue also scheduled it for tomorrow, still acting in the guise of Van Helsing with a cannon in his belly.

With a copy of each of the Six Styles Soul Contracts in his pocket, Li Yue prepared to sign Borgny Copper Spoon on the spot in the underground city.

The demon expeditionary force had set off, and the powerful enemies were not in the Demon King's City, so Li Yue's days were much more leisurely, with plenty of time to complete various preparations and reduce uncertainty.

At the same time, both in the arena and in the underground city, things that Li Yue could hardly predict were happening.

Oogie Boogie went on the expedition with the First Army, while the injured Beelzebub Von was left in the underground area, continuing to recuperate under the protection of high-level gladiators who had suffered more than half of their casualties.

The report letter that Li Yue instructed Menmen to send did not have any effect, Beelzebub Von's days were very good, his lower abdomen had almost healed, and he had already laid hundreds of poisonous fly demon eggs, rebuilding Oogie Boogie's private army, his recovery speed far exceeding expectations.

And the high-level gladiators' days were also relatively leisurely.

A batch died under the magic mirror's damage, another batch was taken away by the First Army, and the Slaughter Cup was suspended indefinitely, so those who were left idle, just waiting to entertain the invading Heroes.

In the underground city, a dwarf whose beard was tied into several small spoon shapes was focused on his scavenging business—the invading Heroes promoted the scavenging business in the Demon King's City better and better, and now, the corpse collectors brought back some scattered good things, clustering near the Dead River in the underground city to sell.

The dwarf picked and chose, bartering with the corpse collectors with his own made broken demon relics, and suddenly saw a piece of broken mirror stained with blood.

"This pile of junk is mine." The dwarf took out a modified silver gun from his beard, threw it to a silent corpse collector, and then swept away the messy objects around him.

Including that piece of broken mirror stained with blood.
