Global Empty-Room Survival: Winning Supplies Through a Lottery

[Saintly protagonist + no System + multiple worlds + one female lead (pure-hearted saint only; if you don't like that, don't read)]

At the start, players around the world appeared in blank rooms measuring just thirty square meters. They could win supplies through a daily lottery. Some people drew a Simmons bed right away and got to sleep in a spacious suite; others drew a whole box of instant noodles and were set from the start.

Some drew monsters and had to start over on the spot. Others got nothing in all ten draws and died of rage.

Our protagonist, meanwhile, accidentally drew a golden card one day. He thought using it would summon the beautiful older girl engraved on it, but due to a lack of magical power, he ended up summoning only a little girl in her child form!

Protagonist: Did I lose out, or did I come out ahead?

NPC: Looks like you're headed for prison!

Note: The main gameplay in the middle and later parts of this book is looting, shooting, and extracting, similar to Tarkov. The early game focuses on survival.
