Natural Disasters: Siblings Start by Scavenging Vegetable Scraps and Become Beloved in Two Worlds

[Cataclysm + travel between worlds + space elevator + farming (golden finger appears later) + adorable child + one heroine + no awful relatives + no fighting] Acid rain destroys the world of Green Star, leaving eight-year-old Nalan Yue all alone and helpless! She wanted a sip of water to stave off her hunger, but tumbled headfirst into a water vat... The jade pendant activated a space elevator leading to a market on Blue Star. From picking up discarded vegetable leaves at first, to bartering the gold from Green Star, where it was practically worthless, for survival supplies with her older brother... The siblings became the whole village’s only hope. After the space elevator was handed over to the government, Xia Country used its gold to crush the world, and controlled nuclear fusion left everyone speechless... From then on, Xia Country entered the interstellar age, established a second homeworld, and saved hundreds of millions of migrant workers. As for the siblings, they joined forces with a few close friends to buy up huge quantities of soil, set up a super farm on Green Star, and began living like immortals.
