Looking at the pink Demon King's Castle in front of him, El felt a great sense of accomplishment.

Having no prior experience in trap construction, he used the knowledge he gained from the Demon King's Crown to complete the modification in just a few days.

The traps and mechanisms inside are all designed to provide unexpected surprises for future visitors!

Which mechanism is El's favorite?

Needless to say, it's the mobile aerial platform on the upper floors of the Demon King's castle.

In the upper third of the Demon King's Castle, there are no normal walkways or complete paths. With the anti-flying module that was recently installed in the Demon King's Castle, visitors can only move by jumping.

The floating platforms move back and forth, and the gaps between the platforms are obvious, making it difficult to complete a jump.

Moreover, by utilizing projection technology, the platform's boundaries were expanded, and the actual platform was not as large as one might imagine.

Imagine someone thinking they've jumped onto a platform, only to lose their footing and fall back to where they started...

El couldn't even imagine how excited and thrilled that lucky person would be at that moment.

What does it mean to be a design that inspires fighting spirit and unleashes potential? This experience is absolutely top-notch!

"I really am a good person..."

Al was already imagining what visitors would face if they looked at the pink exterior and let their guard down about the interior.

"The construction here has been completed. According to the records of other brave predecessors, I seem to have a few more places to check off my list."

"No rush back. The Demon King is finished anyway. Let's stay in the demon realm for a few more days."

Based on the testimony of the vampire duke who sought only death and not life, he could visit other high-ranking demons in the area.

"Let's go, let's go. I wonder if they're waiting for me?"

For the demons in the demon realm, especially the high-level demons, this period was absolutely the worst, darkest, and most tragic time in the demon race's history.

On the day you completely devour the Demon King's crown and gain the power of the demon race, whether it's the vampire prince who has been sleeping for many years, the great demon lord, or the dragon king of the demon dragon branch of the dragon race, everyone will have an ominous premonition.

A shadow, an unknown shadow, enveloped them. No demon knew what was happening, but they sensed impending doom.

They have also learned of your slaying of the Demon King, but none of the spies who went to investigate the Demon King's castle returned alive.

(Some of them were touched by El and turned into ingredients in the pot, while others were lucky enough to arrive after El left.)

Then, they entered the pink Demon King's castle, and not one of them came out alive.

[That's how it is. The demons are in a state of panic, and you come knocking at this time.]

"Help! I beg you, Demon King, please spare us!"

The strongest of the demon race kneels before you, attempting to beg for its life.

[With absolute power and the suppression of authority, this demon was already exerting all his strength just to remain standing.]

[To attack? To resist? The difference in strength is too great. Even without using your demonic authority to bully it, you can still easily crush it.]

"Let you go? How can I do that? I'm hungry now."

You have so much meat, and I have plenty of experience cooking demons. Tell me, how can such a coincidence happen in this world?

As you stated, in the end, amidst the wails of demons and the struggles of some, the Demon Realm—the Demon Capital—vanished into nothingness. The demon race still exists, but its core power has been annihilated.
