Apocalyptic Power Exchange, I Will Win by Picking up Space and Hoarding Goods

Before the end of the world, my sister and I awakened our powers at the same time. Space or beauty, choose one from the two. My sister usually likes to read articles about hoarding goods in the apocalypse. Knowing that space is a good thing, and being the first to take it away, I can only choose beauty. The younger sister sneered, the end of the world is coming, what's the use of being beautiful, just wait and die. My sister used all her family's savings to stock up on goods like crazy. However, the zombie wave of the apocalypse is coming! The world order is in chaos. After having the space, my sister did not live the apocalyptic life she wanted. She hoards a large amount of supplies, causing the doomsday thugs to covet her. In the end, my sister's supplies were all divided up, and she became a mobile warehouse for the strong, suffering all the humiliation. And with my peerless appearance that confuses people, even the most powerful soldier king in the apocalypse fell under my skirt. No need to starve, no need to go out of the base to kill zombies, and you are extremely well protected. When I met my sister again, she was skin and bones, but I was rosy. She threw herself into my arms and cried bitterly, hoping that I could save her. Before I could react, she changed her face on the spot and tried her best to push me into the zombie wave, wanting to die with me. My sister asked frantically: "It's all your fault! If you hadn't robbed me of my beauty and my powers, I would have been the one protected by the King of Soldiers, and I wouldn't be living a life worse than death now!" In severe pain, my body was bitten mercilessly... When I opened my eyes again, I was reborn and returned to the time before the end of the world, when I chose my powers.
