What Challenges Does The Vault Dweller Face In The Story?

The world plunged into a new Ice Age. As the frozen apocalypse spread, 95% of humanity perished. In his first timeline, Cyrus Knovell's kindness cost him everything. The people he had helped betrayed him and left him for dead. Fate, however, granted him a second chance. He awakened one month before the world froze, gaining a dimensional ability that let him store anything without limit. Now he hoarded supplies by the billions and built a fortress no one could breach. While others shivered, starved, and traded their dignity for a morsel, Cyrus lived in comfort. The desperate came begging. The manipulative vixen: "Cyrus, let me into your shelter, and I'll be your girlfriend, okay?" The spoiled rich heir: "Cyrus, I'll give you all my money for just one meal!" The greedy neighbors: "Cyrus, you shouldn't be so selfish. You should share your supplies with us!" Cyrus remembered their betrayals. Lounging in his steel fortress and savoring his private paradise, he sneered, "Your survival has nothing to do with me. I'd rather feed the dogs than feed you."

After I was caught in a dockside explosion, I was bound to a Survival Program. It gave me twenty-five years and four designated targets. If even one target’s Love Score or bond score reached 100%, I could wake up in my real world. But I failed all four. Because every target I tried to reach eventually turned toward Sophia Lane, the heroine of this world. They called my pain a performance. They called my tears manipulation. They said I was only pretending to break down so they would choose me over Sophia. But if they never loved me, why did they lose control when my mission failed and I chose to leave this world for good?

On a stormy night during the apocalypse, my own mother threw me out of the house while I was burning with fever, along with my husky, so my little brother would have a better chance of surviving. She shouted through the crack in the door, “Take that useless mutt and go die somewhere. Stop wasting your brother’s food!” I huddled in a pile of trash with my dog in my arms, convinced I was going to die. Then my husky suddenly spoke. “Host’s vital signs critically low. Infinite Supply Search System activated.” “Supermarket warehouse one hundred meters ahead. Three thousand freeze-dried meals detected.” “Pharmacy five hundred meters to the left. Five hundred boxes of antibiotics detected.” Three days later, I’d built a fortress with packs of dogs and mountains of supplies. I sat inside eating steak and watching the show. Outside the barbed wire, my mother and brother were on their knees, fighting each other over half a piece of moldy bread. I smiled. “Mom, even dogs wouldn’t eat that. Better savor it.”

In October 2025, an explosion occurs at a remote lab. An unidentified substance is leaked, and the virus makes people go insane. Anyone who is bitten by these rabid creatures becomes one of them. It's like the zombies people see in movies and video games. On the first day of the explosion, my five-year-old, Joyce Fairfield, is still at kindergarten. I risk my life to hurry there, but I can't even find her corpse when I arrive. I can only look at the surveillance footage to see her face, which is ashen with fear. I also see her mouth, "Mommy!" 15 days after the explosion, I finally traverse the city and get to my mother's home. However, all that welcomes me is a destroyed apartment and blood everywhere. 20 days after the explosion, my husband, Emmett Fairfield, calls me one last time from his office, which zombies have surrounded. He tells me not to leave the house. Less than a month after the apocalypse arrives, I lose all my family. I'm alone as I struggle to survive in this dead world. The spread of the virus triggers chaos in mankind. I exchange all my supplies to save a neighboring couple from bandits, leading them to safety in a secure zone where they can live stable lives. However, my kindness is not repaid. Three years after the explosion, the secure zone is under siege by a wave of zombies. As we retreat, my neighbors shove me underneath a car so I'll distract the zombies. Then, they make a run for it and get away. Trusted neighbors betray me. As the zombies eat away at me, I can feel death looming. All I want is to see my family again. Now, I've been reborn. I have six hours before the zombie apocalypse breaks out.

The city was overrun by zombies. My girlfriend, Callie Bernson, the team leader, had taken my best friend, Dan Harrington, and fled in our only armored vehicle, leaving me behind in the shelter to die. Outside, the scratching of claws against metal echoed through the corridors. The defensive barricades were already starting to fail. My heart sank into despair. I raised my gun to my temple, ready to end it quickly, when a stream of floating text suddenly appeared in front of my eyes. [It’s hilarious. That cheating couple thinks they’re heading to Paradise, but that place has fallen. It’s packed with high-level zombies now.] [Don’t die, PC! The person in a coma in the shelter—the one your so-called best friend called dead weight and abandoned—is actually the only S-class ability user. Once she wakes up, she’ll wipe the floor with everything!] [Just you wait. When your buddy crawls back here in disgrace and finds the big boss awake, he will go to step in and steal the credit for saving her.] [Hurry up and die already, cannon fodder. I can’t wait for the tragic apocalypse romance between the best friend and the big boss.] I lowered the gun and sprinted toward the quarantine room. Inside, a woman lay on the bed, sleeping peacefully. I strode over and slapped her hard across the face. “Honey!” I shouted. “Time to get to work!”

On New Year’s Eve, my fiancee, Delilah Carrington, left me to freeze to death in subzero snow. As my body went numb, she was wrapped in the military coat I had found for her, curled up in Everett Kingsley’s arms while eating the holiday groceries I had paid for. When I opened my eyes again, I was back before everything fell apart. So when she called—cold, demanding, rattling off a shopping list like I owed her—I hung up, blocked her number, and made my move. I sealed off Blackridge Logistics Hub, the largest logistics hub in the country. Stockpiling supplies? Pointless. Because my coworkers and I had more packages than we could ever open: seafood delicacies, premium cigars, top-shelf liquor, and industrial generators. Hundreds of millions of shipments meant for the holidays were now all mine. Inside a warehouse kept at a steady 26°C, I ate wagyu steak and watched the world collapse through surveillance feeds. I witnessed Delilah’s entire family tear each other apart over half a moldy pack of crackers. I thought I could live like this forever. I was wrong. In the apocalypse, the most dangerous thing isn’t what’s waiting outside. It’s the people who refuse to stop playing the hero.
