In a high-tech corporate world, a burned-out technician collapses from overwork, only to wake up in the body of a mysterious man inside an abandoned underground shelter. Confused and trapped, he soon discovers a system interface guiding him with blueprints, missions, and survival tasks. His first challenge? Restore power to the shelter—or remain in the dark, both literally and figuratively. With food rewards and the promise of uncovering the truth about his new reality, he embarks on a journey of survival, technology, and self-discovery in a post-apocalyptic wasteland.

The world of disaster: become the admin of the shelter

Cris sat at the admin desk, staring at the blueprints of the entire shelter displayed on the glowing screen in front of him.

With a tap, he selected the Storage Room, and suddenly, a 3D hologram of the room appeared above the table. It showed everything inside—food, tools, and random junk—along with upgrade options.

Cris smirked. "Damn, this is high-tech."

As he scrolled through the interface, his eyes landed on something strange.

At the bottom of the system menu, there was an option labeled "MS".

A robotic voice echoed in his mind:

[MS: Money System. You can use MS to upgrade the shelter.]

Cris raised an eyebrow. "So I need MS to make upgrades? How much do I have?"

With a shrug, he closed the menu and called out, "Trixie, guide me to the Training Ground."

Trixie appeared beside him, her usual bright self. "Of course, Master! This way."

They arrived at a large set of double doors. Rust covered the metal, and the air smelled of dust and old sweat.

Cris used the keys that's he get as a reward to open the door, revealing a massive underground facility. The training ground was huge, like an abandoned stadium, but it was a complete mess—broken dummies, shattered weapons, and dust covering everything.

As he stepped inside, the system popped up again:

[New Quest: Clean the Training Ground]

Reward: Food (transferred to Storage Room) + 5 MS

Cris clenched his fists. "Alright, it's cleaning time!"

He grabbed an old mop and broom from the corner and got to work.

As he swept the floors, he found something interesting—a strange training device half-buried under some debris.

Cris tilted his head. "Huh? What's this?"

He called out, "Trixie, what is this thing?"

Trixie floated over and scanned it. "Master, this is an automatic training dummy. Soldiers used it for combat practice."

Cris grinned. "So it still works?"

Trixie shook her head. "No, it needs repairs."

"Figures." He sighed, making a mental note to fix it later.

As he continued cleaning, something caught his eye—a huge cracked sword leaning against a wall.

The blade was covered in rust, but even in its damaged state, it looked incredible.

Cris walked over and ran his fingers along the blade.

It felt like the sword was calling to him.

"I… I don't know if this is love or what, but…" he muttered.

He stared at the weapon, completely mesmerized.
