I Stride Through the Apocalypse, Stockpile a Hundred Billion, and Dig Into the Earth

[Stockpiling Supplies + Reborn + Space + Sweet Romance + Satisfying Read + One-on-One, Both Chaste + Dominant CEO Heroine + Female Pursues Male]

(My dream is to dig out the entire Earth. Mom and Dad were so heartbroken that they gave me the huge inheritance I love so much, worth tens of billions.)

My name is Ruoxi. My parents don't like me, and my grandparents don't love me.

When it was time to divide up the inheritance, my parents, whom I had only seen a few times in twenty years, brought home an adopted daughter and wanted her to inherit it.

The inheritance that should have been mine was stolen, and my idealized fiancé fell in love with the adopted daughter too.

The apocalypse came without warning. My family and the person closest to me shoved me into a horde of zombies, leaving no trace of my remains.

Reborn before the apocalypse, I forcefully claim my inheritance and gleefully stockpile supplies!

I hire a huge workforce to build an underground survival shelter that's impervious to bullets and guarded as tightly as a national network!

One day, while I savor a feast of delicacies cooked by my sweet young boyfriend, I watch my once-arrogant parents and grandparents fight over a bottle of water on the security monitors...

A friendly warning: There is a male lead. He's love-struck, a top researcher, and a sweet young man who pretends to be silly. He's also an excellent cook.
