[The end of the world + superpower + upgrade + stocking up + vest + growth + easy direction] The end of the world is coming, global changes, whether it is disaster or hope. Mutated animals and plants are coming one after another, past advanced technology has regressed, and past laws and ethics are no longer bound. Where should mankind go from here? After waking up one day, Tang Guo recovered most of his lost memory. In a deserted valley, her sister, who was so close to her, was not around. Collect exotic pets, open up space, stock up on supplies... She showed off her skills and took advantage of the opportunity to stock up crazily. Adhering to the principle of taking as much as she could use, she vowed to pluck out the "wool". Mutated fruits that can be upgraded, supermarket department stores, livestock in the fields... Tang Guo waved his hand and took them all away! This time, it was her turn to protect her sister—— But when we finally met, my sister seemed to have "changed", and she seemed to have an ulterior secret hidden in herself... "Sister, who are you?"
