Heavens, Jing Shu had longed for a mobile villa for a very, very long time. She had thought about it when she first set up the Red Worm Factory.
She'd also chosen that location to establish the Red Worm Factory because of its geographical position. It had remained almost untouched by natural disasters for ten years during the apocalypse, and it was a place they were bound to return to a few years after relocating.
Of course, they did live comfortably for a while after relocating. However, in the apocalyptic world, not every place remained suitable for long-term habitation. Areas became uninhabitable, and for various reasons, they were forced to return.
By that time, Wu City was already devastated, with very few livable and suitable places remaining. The Red Worm Factory was one of those precious, habitable spots. Back then, even the villa she currently lived in wasn't as ideal.
