Back in the Apocalypse, I Turned Myself Over to the State

My younger sister brought home a man who was lame and blind, but soon lost patience with caring for him. She dumped him on me and went traveling to another province. But on the third day after she left, the apocalypse suddenly arrived. Under my care, the man recovered. He not only awakened powerful abilities, but also treasured me above all else. When we met again, my sister was disfigured and missing a hand, while I lived in comfort. Jealous of everything I had, she went so far as to lure mutated zombies over to wipe us all out. When I opened my eyes again, my sister shoved a packed suitcase into my hands and pushed me out the door. “Big Sis, this time you go on vacation. Leave taking care of him to me!” I turned and left without hesitation. Without my storage space and spirit spring, let's see how you'll become the leader's wife.
