Creating a Great World in a Cardboard Box

The day the natural disasters began,

I found a cardboard box.

To survive this catastrophe,

I secretly created a world inside the box.

It was larger than Blue Star.

I dropped in a single drop of water, and it became a vast ocean.

I placed an ant inside, and it grew into a world full of beasts and humans with all kinds of extraordinary skills.

They all called me "God."

The main story is told in third person; the blurb is in first person.

Apocalypse + world creation + Fourth Calamity + wish fulfillment + power progression + mastermind behind the scenes

The female lead is very strong and very reliable. Trust her.

The main plot takes center stage. Although many supporting characters have feelings for the female lead, this is still primarily a plot-driven story.

Theme: Strive tirelessly to improve yourself and uphold justice in your heart
