Returning to the End of the World, I Surrendered Myself to the Country

My sister picked up a lame and blind man, but she didn't have the patience to take care of him. After leaving the person to me, I chose to travel out of the province. But on the third day after she left, the end of the world suddenly came. But the man recovered under my care. Not only did he awaken powerful powers, but he also treated me like a treasure. We met again, my sister was disfigured and her hands were broken off, but I was pampered. My sister hates everything I have and will not hesitate to attract mutated zombies to destroy us all. When I opened my eyes again, my sister stuffed the packed gifts into my hands and pushed me out of the door. "Sister, it's your turn to travel this time, just leave it to me to take care of people!" I turned around and left without hesitation. Without my space and spiritual spring, I want to see how you can become the leader's wife?
