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

As Cris admired his newly crafted grenades, a sudden notification appeared in front of him.

[Congratulations! You have created a new explosive: "Glue Bomb."]

[New Item Registered: Glue Bomb – A sticky explosive that immobilizes targets before detonation.]

Cris blinked. "Wait… the glue bomb actually counts as an invention?"

He glanced at the pile of hardened goo from his earlier failure.

"Hah! So my mistake turned out to be useful after all."** He smirked, grabbing one of the solidified glue samples.** "Guess I accidentally invented a non-lethal trap."

[Reward for creating a new bomb: A box of food (Transferred to Storage Room)]

[New Title Acquired: "Innovative Craftsman"]

Effects: Increased efficiency in crafting, reduced failure rate, and improved power.

Cris grinned. "Oh hell yeah, that's what I'm talking about, body enchantment!"

I can now go to that's little Zeezo with this body enchantment.

Then Suddenly, another notification flashed.

[New Quest: Eliminate the Zeezo Infestation]

Objective: Clear out the Zeezo near the Maintenance System.

Reward: Key to the Training Ground (Where soldiers were once trained).

Bonus Reward: ??? (If the Maintenance System is repaired after elimination.)

Cris crossed his arms. "A training ground, huh? That sounds useful."

Trixie tilted her head. "Master, the Training Ground was where the soldiers of the shelter trained in various combat techniques. If we gain access, it may provide valuable resources and even combat programs for learning."

Cris grinned. "So, if I finish this, I basically get an armory and training manuals? Sweet."

Then, his eyes landed on the bonus reward.

"And what's this mystery prize?" He rubbed his chin. "Now I'm even more curious."

Trixie hovered beside him. "Master, the Maintenance System controls power distribution, door access, and automated defenses. If you restore it, the shelter's functions may improve significantly."

Cris stretched his arms. "Sounds like I get a jackpot if I finish all of this."

He turned back to the table of grenades and smirked.

"Alright then… it's time to introduce these little guys to some Zeezos."
