Reborn Before the Apocalypse Began

This novel has no romance.

Shu Shu was reborn. In her previous life, she had no special abilities or pocket dimension. She struggled to survive for three years in the apocalypse, only to die in a zombie horde.

In this life, the house her parents left behind had yet to be seized by her uncle’s family, so Shu Shu decisively sold it and stocked up on a mountain of supplies.

When the apocalypse came, others fought over a packet of instant noodles while Shu Shu enjoyed a hot pot feast. While others cursed the heavens for cutting off their water and food, fresh vegetables overflowed from Shu Shu’s pocket dimension. While others fled from zombies pursuing them on all sides, Shu Shu swept through hordes of zombies with lightning in one hand and jets of water in the other. While others dared not sleep soundly at night and had to take turns keeping watch, not even a fly could get inside Shu Shu’s iron fortress...

(The protagonist is incredibly powerful and no pushover.)
