Back to the End of the World, I Use My Pocket Dimension to Raise a Zombie King

In her previous life, He Sui'an took in her great-uncle's family, only for them to shove her into a horde of zombies, leaving not a single whole piece of her body.

Reborn before the apocalypse, she awakened a portable space complete with spiritual spring water and fertile black soil.

Relying on her memories from her past life, she sold her house, stockpiled supplies, built a safe house, and face-slapped her awful relatives.

She thought she could live in peace, but then she accidentally picked up a zombie, and it insisted on being adopted.

Fine, then. She'd raise it.

Who knew this zombie would not only have absurdly high combat strength, but also come with lightning abilities? It was practically an apocalypse essential for home and travel.

So while everyone else was busy fleeing for their lives in the apocalypse, she directed zombies in her space to hoe the fields, water the crops, expand the grounds, and cook...

The fields kept growing, and the harvest kept piling up.

But why were the zombies she raised multiplying, too?
