RV System: My Wife and I Brave the Apocalypse

[Two female leads + post-apocalyptic world + supernatural powers + System + both leads are each other's only one + slow burn + ensemble cast + no romance right from the start + the two leads don't interact much early on; plot comes first]

I woke up one day. Had I transmigrated? Awesome!

What?! I'd transmigrated into a post-apocalyptic novel? The kind with zombies?!

Can I transmigrate back? I don't want to get bitten!

Yiqi looked at the original owner's already meager living conditions, and the fact that she had a dog, too. What was this? One person and one dog, just like I thought?! A disastrous start! Stocking up and reinforcing the house? Where was I supposed to get that much money?!

The System suddenly appeared and spoke to Yiqi in a rather boastful tone. “Host, not only have I provided you with a luxury RV that combines living space, a home, and transportation, but I also...” Halfway through its sentence, the System, a bundle of virtual data, suddenly felt a chill down its back.

Ruan Shuxian smiled warmly at the System. “You'd be better off keeping quiet about things you shouldn't say.”

“Wait, you look familiar. Are you the one the original, ” Uh, the girl the original owner had a secret crush on. But why did her smile seem so terrifying?

Never mind. The most important thing now was to get out of here, then drive the RV and explore the new world.
