The apocalypse arrived, and Irving was betrayed and killed by his own girlfriend.
After his rebirth, he was chosen by the Will of the Blue Star to be an internal beta tester of the Shelter Game, starting with a [Tenfold Drop Rate] and becoming a [Necromancer]!
Ferocious and brutal exotic beasts are all tamed by him, gradually forming a powerful "Exotic Beast Legion" under his command!
Building sanctuaries, hoarding supplies, upgrading outer walls, setting traps...
Constructing the most powerful fortress in the apocalypse!
"Since I have been given a second life, I will trample those who've betrayed me once under my feet!"
...
When the Dark Lord descended, Irving's shelter had become the strongest on the Blue Star!
"You evil creatures, dare to covet Blue Star?"
"Come on! Let me show you what true despair is..."
"Remember, from now on, Blue Star is under my protection! Got it?"
