[You have made your choice. The Platinum Luxury Apartment is about to be promoted to "Demon King Castle"!]

The Dorm Survival Game sent out a notification, and Xu Lang waited quietly.

Dorms like Asura Home sank into the ground, but the Evolution Dormitory surprisingly didn't disappear.

"Hmm?"

Xu Lang raised an eyebrow.

This dormitory was supposed to be a special dorm that only appeared after using a Data Obelisk. Could there be a catch?

As it turned out, Xu Lang wasn't wrong. This Evolution Dormitory actually did have a special meaning!

Under his watchful gaze, it suddenly exploded into a sea of data, which surged into the Demon King Castle, as if enchanting it.

[Data anomaly... Evolution Dormitory and Demon King Castle have extremely high compatibility... Demon King Castle is mutating... Demon King Castle has evolved into True·Demon King Castle... "Alchemy Workshop" unlocked at level thirteen, "True Attribute Dimension Ascension Device" unlocked at level fifteen... Remaining source matter has been fused into True·Demon King Castle]

Before Xu Lang could figure out what this series of changes meant, he was already back in reality.

...

"Xu Lang, what's wrong with you!?"

"Lang Ge, are you okay?"

"Lang..."

The moment Xu Lang opened his eyes, he saw the women crowding around him, not a single one missing.

Their faces were full of anxiety, as if they thought something had happened to him.

Calming his mind, Xu Lang replied, "I'm fine. I just upgraded the dorm to level ten."

"Level ten? Lang, weren't we only able to upgrade to level nine at most?" Sherry said in surprise.

Xu Ruyan said thoughtfully, "It should be because Xu Lang used that Data Obelisk."

The Data Obelisk was dropped by the Apocalypse Fighter Jets. She thought Xu Lang would try to level up a bit more before using it, since this thing was very precious.

She didn't expect Xu Lang to be so decisive.

Then again, in the Dorm Survival Game, immediate benefits were important. Most people couldn't afford to save the chicken leg for last, because that was a good way to starve to death.

"Data Obelisk?" Cao Yaxuan had never heard of this thing before.

Xu Ruyan explained briefly, and everyone understood immediately.

And at this moment, the dorm had already begun to change.

This change had a kind of silent beauty. The walls faded, as if an old photo was being washed of its gray stains, or as if spring was speeding up ten thousand times, the meadows growing wildly.

Everyone waited calmly for the final transformation to arrive, and for a moment, no one made a sound.

Xu Lang was thinking. What exactly was that True Attribute Dimension Ascension Device? He could sort of understand the Alchemy Workshop, but the True Attribute Dimension Ascension Device was completely incomprehensible.

Later, when Golden Dawn had their meeting, he could ask the Lord of Dawn, or ask Brahman.

Radio players had a much higher survival rate than ordinary players, since they were all Top Players. So Rainy Night Blade and the others were still alive and well.

The dorm's transformation lasted over ten minutes. The change could be described as earth-shattering, evolving from the original Luxury Apartment into a small world of its own!

...

The internal layout of the Demon King Castle was very unique.

The oak door slowly closed, completely cutting off the noise of the outside world.

Those who stepped inside felt as if they had not entered a safe dormitory, but rather, they had entered the body of a "king."

The foyer's ceiling was towering, hidden in a deep purple gloom, with what seemed like a slowly rotating nebula above. The load-bearing pillars on both sides were like obsidian, engraved with mysterious patterns, luxurious and enigmatic.

Underfoot was a dark red fungal carpet that would automatically squirm with the steps of those who walked on it, soft and comfortable.

Here, there was a meeting table and high-backed chairs, and there were not just one seat. There were sofas, small tea tables for drinking tea—everything one could need.

The door leading to the main hall was on the right.

There was a thick patch of shadow there. Without the owner's granted permission, no one could enter.

The main hall of the Demon King Castle was similar to the foyer, also laid with a dark red carpet, but the more open spaces were a floor of black jade-like stone, giving it more of a homely feel.

It was like the heart of the Demon King himself.

The fireplace crackled, the flames within seeming like dark red energy.

Classic sofas and a coffee table were placed right in front of the fireplace. It would be just right for a family gathering here; it seemed like only a television was missing.

On the walls of the main hall were some cat's eye gems and black gemstones. Their meaning was unclear; they seemed to be purely decorative.

The door here was the Golden Fortune Auspicious Door. On the wall beside the door, a skeletal hand held a crystal ball, within which a fierce flame condensed, making it look somewhat special.

Next to the Golden Fortune Auspicious Door were, on the left, the Meteor Summoning Device, Cannon, Berserk Laser Ray Emitter, Angel Turret·Left; on the right, the Void Fissioner, Berserk Laser Ray Emitter, Angel Turret·Right.

It was worth mentioning that modern-looking core facilities like the Radio, Surveillance Camera, and Air Conditioner had also undergone slight changes in appearance, better fitting the noble and majestic tone of the place.

A spiral staircase led to the second floor.

The second floor had a full corridor overlooking the lower level, ten single rooms, twenty secondary bedrooms, and one master bedroom with its own private balcony.

The space within the dorm was folded. This corridor of about a hundred meters could hold over a hundred turrets, but from the outside, it didn't appear particularly wide.

Currently, the Demon King Castle only had these two floors.

And the built-in functional facilities totaled eleven!

First, the Living Carpet, which automatically cleaned and optimized the air.

Second, the Oak Door, which was right next to the Golden Fortune Auspicious Door, leading to the foyer. It didn't have the defensive properties of a facility door, but monsters couldn't break it down either. It was specifically used for receiving guests or for hiding ambush troops.

Third, the Annihilation Crystal Ball. If the main door was breached, the flames within the Annihilation Crystal Ball would be released, dealing a massive amount of true damage to the enemy.

Fourth, the Second-Floor Library. Players in the library could quickly understand the knowledge within books.

Fifth, the Second-Floor Observation Deck, which allowed a three-hundred-sixty-degree view of the surroundings of the Mad King Building. One turret could also be moved there to attack in all directions.

Fifth, the Back-Hall Plantation, where crops could grow quickly. There was also a continuous irrigation channel. Watering the Spirit Field with "Terror Force" could improve the quality of the field.

Sixth, the Demon Eye. The Demon King Castle's owner and all tenants could consume "Terror Force" to generate "Demon Eyes" on the body of the Mad King Building, used to observe every corner of the building. Demon Eyes could not be directly manifested inside other people's dorms.

Seventh, the Training Rooms, which were on both the first and second floors. They could enhance training efficiency.

Eighth, the Abyss Whisper Door, located in the basement. After each game cycle, a Nether Jaws Beast could be summoned from here, with 100% loyalty. It could also be enhanced using "Terror Force."

Ninth, the Terror Pedestal, which could generate "Terror Force." Terror Force was the second energy source of the Demon King Castle, distinct from Copper Coins. Currently, the Demon King Castle had only one Terror Pedestal. Each time the dorm was upgraded, an additional Terror Pedestal would be added. The terror that living beings felt towards the Demon King Castle would speed up the generation of Terror Force.

Tenth, turrets could be mounted at the secondary bedroom windows. The owner and tenants could also teleport between secondary bedrooms with zero frame delay.

Eleventh, each time the dorm was upgraded, a new ability would be unlocked, and an additional floor would be added.

Basic attributes—Tenant count: 20, Turret count: 12.

Basic upgrade attributes—Each upgrade, Tenant count +1, Turret count +2.

After all the women understood all the attributes of the Demon King Castle, they were all utterly shocked.

"This isn't a dorm at all. It's a super war fortress that can suppress an entire building!" Cao Yaxuan said, clutching her heart in awe, her words barely a whisper.
