He built fortified shelters and hoarded mountains of supplies. In this new life, he would make his ex-wife and her family pay—every last one of them. No more groveling. No more weakness. This time, Ray would rise above it all.

I get reborn, this time bound to a simp system. In my previous life, when the apocalypse happened during Christmas Eve, I gave Victoria Blake, a beautiful woman, shelter and respite, only for her to backstab me in the end. Apparently, she had revealed my home's location to a scion named Tristan Cole when I wasn't paying attention. Not only did those bastards take over my shelter, but they also tossed me to the zombie horde. When Tristan asked Victoria if she felt guilty, she just reclined in his arms while tittering daintily. "That's just one of the lapdogs I've reared. If he's dead, then so be it." Now that I'm given a second chance at life, I'll make sure to repay them for the pain and hurt they've caused me in my previous life.

In a drought-ravaged apocalypse, I kept our entire apartment block alive with my “watermaker” ability. But when I grew weak, my neighbors shattered my limbs and turned me into a living water source. Later, when raiders stormed in, they dragged me out to take the blade for them, only to realize that even my severed arms could still produce water. So, they shouted about “saving humanity,” then shoved me into the crowd and fled in the chaos. People rushed forward one after another, tearing at my flesh. But I didn’t die. What was left of me fell into the hands of a monster, and I was subjected to inhuman torment day after day. Ten years later, when the apocalypse finally ended, that monster tossed me into an incinerator. Only then did I die. When I opened my eyes again, I had returned to the moment I first awakened my ability, just as my neighbor knocked on the door, begging for water.
