The Apocalypse Is Here, and I Rule My Corner of the World with Seeds

[Rebirth in the Apocalypse + Two Powerful Leads + Superpowers + Stockpiling Supplies + Love That Grows Over Time]

The apocalypse arrived, and Mu Mu fainted!

When she woke up, she found she had formed a bond with a flower! She had also suddenly gained a pocket dimension!

The place was nothing but barren wasteland, until one unintentional discovery: Mu Mu realized she could upgrade it using crystal cores...

One day, after taking out a big handful of crystal cores, Mu Mu looked at the still-barren space and complained helplessly, "It takes way too many crystal cores! How am I supposed to fill this place up?"

And that powerful person she met seems to have quite a story! Why are they so cold and aloof, and so hopeless at dealing with people? They're hardly even human! Could they be a zombie?
