Picking up Trash in Another World, Bringing it Back to the Apocalypse for Construction

When Sang Chu was killed by people from her own Base during the Apocalypse, she unexpectedly boarded a strange Train.
When she woke up again, she had arrived in another world!
The Train Elf told her there was only one way to survive—earn money diligently!
And so—when someone asked if they could purchase the Trash on her.
Sang Chu: Hesitating for even a second is disrespecting money!
Monsters are very valuable?
Sang Chu: Decisively head out of the city to Hunt Monsters!
She didn’t awaken a Supernatural Ability in the Apocalypse, but she didn’t expect to awaken one in this otherworld!
However, the Train would forcibly send people back to the Apocalypse.
But it’s fine, she has money now!
Fruits and Vegetables, Clean Water Source, buy, buy, buy!
Hovercars, Optical Computers, high-Technology items, nothing is missing, arrange them all!
Returning to the Apocalypse, she wants to build her own Peach Blossom Spring Base!
The next time she boards the Train for a trip, she needs to purchase the Train Ticket at double the premium?
No worries, she found a Spirit Stone Mine in the Apocalypse, we don’t lack money!
