Yuan Shenzi woke naturally inside his blanket nest as the weak gray light of Day 2 filtered through the snow-covered windows. No alarm, no rush. Just perfect, enveloping warmth. The multi-layered thermal blankets had kept his body temperature stable throughout the night, eliminating the violent shivering that had nearly killed him on Day 0. There was only a faint stiffness in his back from the hard floor, nothing compared to the deadly cold waiting outside.
He sat up slowly and reached for one of the cardboard boxes nearby. Tearing open a vacuum-sealed pack, he bit into a high-calorie ration bar. The dense, slightly sweet-savory texture filled his mouth. Each bite delivered steady, reliable energy. No hunger pangs. No fear of running out.
Day 2. No hunger, no freezing. If this pattern continues, survival is no longer the question—sustainability is.
He ate deliberately, chewing each piece fully before swallowing. Afterward, he carefully folded the unused blankets from the night and stacked them neatly to one side. Even with an infinite supply, old habits of orderliness remained. Waste was inefficiency, and inefficiency could kill.
With his morning routine complete, Shenzi began the day's real work: turning the supermarket from a temporary refuge into a fortified shelter. He started at the main entrance. Using his gloved hands and the store's own heavy metal shelves, he dragged display cases and shelving units one by one to reinforce the existing barricade of shopping carts. Each piece locked into place with deliberate precision, creating a thicker, more solid wall against intrusion.
Next came the windows and broken glass doors. He pulled out dozens of thermal blankets, layering them into thick insulated curtains. He draped them carefully over every exposed glass surface, using duct tape and heavy cans of food to weigh down the edges and seal gaps. The blankets blocked the worst of the wind and drifting snow while still allowing faint gray light to seep through. The interior grew noticeably quieter and warmer as drafts disappeared.
The physical labor was demanding, but manageable. Sweat formed lightly on his skin beneath the winter coat, a strange, almost luxurious sensation in this frozen world. Every twenty minutes he paused, retreating to his camp to rest under the blankets and eat another ration bar. The contrast was stark: inside, controlled comfort; outside, lethal cold.
By mid-morning, Shenzi shifted to a more systematic inventory of the supermarket's existing stock. He moved methodically through the ground floor aisles, cataloging what was available. The food section held hundreds of canned soups, vegetables, meats, and preserved goods, many frozen solid, but potentially edible if thawed carefully. Bottled water sat in crates, some still liquid. The clothing aisle offered additional winter jackets, boots, and gloves, though the selection was limited since the apocalypse had struck before the winter season fully arrived. Basic tools, cleaning supplies, and a small selection of batteries (most dead) rounded out the useful items.
He calculated mentally. The store's finite supplies would last one person several months if rationed carefully. Combined with his infinite thermal blankets and high-calorie rations, the equation changed dramatically. Warmth and food were now permanent. Defense and lighting remained priorities. He noted the locations of the service stairs and elevator leading to the upper floors and underground storage. Those would come later, once he had better tools or light.
In the afternoon, Shenzi created a small observation slit in one of the insulated blanket curtains covering a higher window. He positioned himself carefully and watched the street for a long time.
The scene outside had worsened. Small groups of survivors, two to four people at most, moved desperately through the deepening snow. Some dragged furniture from nearby buildings, burning it in makeshift fires for a few precious minutes of warmth. Others scavenged abandoned cars, ripping out tires to feed the flames. In one alley, a man slipped while running from zombies and fell. Frost spread across his exposed skin with terrifying speed, stiffening his limbs before the slow-moving creatures even reached him. His body became another frozen corpse half-buried by fresh snow.
Zombies were increasing in number. Their frost-encrusted forms shuffled with relentless persistence, drawn to any sound or flicker of heat. A few displayed subtle changes—faint glowing blue veins visible beneath their icy skin, and ice seemed to spread unnaturally fast around fresh bodies, creeping like living frost.
Shenzi observed it all with clinical detachment.
They burn what little they have for minutes of warmth. I have infinite layers of it.
No guilt stirred in him. Only quiet calculation. Human desperation followed predictable patterns under pressure. Panic led to mistakes. Mistakes led to death. He had chosen differently.
As the weak gray light began fading into another long evening, Shenzi returned to his camp and improved his sleeping area further. He constructed a more enclosed "room" using additional blanket walls, creating better heat retention. He built the sleeping pad thicker with multiple layers, turning the simple nest into something closer to a proper insulated shelter.
For dinner, he ate another high-calorie ration and experimented. He pressed a thermal blanket against a can of soup taken from the shelves, using his own body heat and the blanket's gentle warmth. After some time, the contents thawed enough to become lukewarm. He opened it and drank directly from the can. The faint taste of vegetables and broth felt like a small victory.
Night fell completely. The blizzard howled louder, and the zombie moans outside intensified, echoing right against the reinforced walls. Shenzi lay back in his newly fortified blanket shelter, warm, fed, and surrounded by growing defenses. The soft, steady heat of the blankets wrapped around him like armor.
He had made real progress today. The supermarket was becoming something more than just shelter, it was starting to feel like a base.
Yet as he drifted toward sleep, one analytical thought lingered in his mind.
One man could fortify a building.
Holding it forever alone, however, might prove… inefficient.
