Apocalypse: Ten Billion in Supplies

[Apocalypse + pocket dimension + reborn + pets + no CP + stockpiling + zombies + steadily growing invincible strength + far higher levels + lighthearted]

In her previous life, Bai Jing struggled to survive in the apocalypse, only to be betrayed by someone she trusted. In the end, they died together. Reborn, she returned to the days before the apocalypse began. Drawing on her memories of her previous life, she stocked up on supplies in advance and awakened an exceptionally powerful mutated ability. This time, no matter how zombies surround her or people scheme against her, she can handle it with ease and crush every obstacle with her strength, determined to make her mark in the apocalypse.

Mindless leveling!!!
