Back Before the Apocalypse, I Handed Myself Over to the State

My cousin found a woman who was lame and blind, but had no patience to care for her. After dumping her on me, he went on a trip to another province. But on the third day after he left, the apocalypse suddenly arrived. Under my care, the woman not only awakened powerful abilities, but also protected me for ten years during the apocalypse. When we met again, my cousin was disfigured and missing a hand, while I had everything I needed. Jealous of everything I had, he even lured mutated zombies to wipe us out. When I opened my eyes again, my cousin shoved his packed luggage into my hands and pushed me out the door. "Cousin, this time you go on the trip. Leave taking care of her to me!"
