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. She died without a body left intact.

Reborn before the apocalypse, she awakens a portable space complete with a spirit spring and fertile black soil.

Armed with memories from her past life, she sells her house, stockpiles supplies, builds a safe house, and gives her awful relatives a taste of their own medicine.

She thinks she can live in peace, but then she accidentally picks up a zombie, and it insists on being adopted.

Fine. She can raise it.

Who knew this zombie would be ridiculously strong and even wield lightning powers? It's practically a must-have for surviving the apocalypse.

So while everyone else is busy running for their lives, she directs zombies in her space to till the soil, water crops, expand the grounds, and cook...

Her fields keep growing, and her harvest keeps piling up.

But why does she keep ending up with more and more zombies?
