Beyond the city walls, a deep trench stretched like a grim chasm, separating the base from the threats beyond. The trench was dug to incredible depths, its steep walls plunging almost vertically, making it daunting to approach. The depths of the trench were dark and damp, filled with an unsettling atmosphere. Within the trench, densely packed with sharp spikes. These spikes were forged from solid metal, their blades gleaming coldly in the dim light. Some stood upright, some tilted, and their staggered arrangement formed a deadly jungle of thorns. Any creature that stumbled into them would be mercilessly impaled. Besides the spikes, the trench was also meticulously laid with a variety of insidious traps. Some were covered in a thin layer of camouflage, appearing to be ordinary ground, but under pressure, they would instantly collapse, sending zombies plummeting into bottomless pits. Others concealed razor-sharp blades that, when triggered, would suddenly spring forth, delivering a fatal slash. In certain areas of the trench, massive wooden spikes were placed. These stakes were firmly fixed to the trench floor, their tips pointed upward, as if waiting for prey to fall into their trap. To enhance the barrier, the trench was strewn with sharp stones and broken glass, making it difficult for the zombies to gain a foothold during their attack. When the zombie horde surged forward, the trench, studded with spikes and traps, became an impenetrable death zone, significantly slowing their attack and buying precious time for the base's defenses.

Inside the defensive zone, a vast area served as the resource gathering area. The terrain was diverse, with rolling hills, gentle slopes, and winding streams weaving through it. The first thing that caught the eye was a dense forest, with towering trees reaching up to the sky. Sunlight filtered through the leaves, casting dappled shadows. The trees varied greatly, from sturdy oak, useful for construction and crafting, to soft pine, an excellent source of fuel. Gatherers moved carefully through the wood, selecting suitable trees for felling and stacking them neatly. At the edge of the forest lay an open quarry. Huge blocks of stone lay exposed, and gatherers, using hammers and chisels, diligently hammered away usable pieces. These stones would be used to build fortifications and houses. Along the stream lay a fertile land, home to a variety of wild herbs and edible plants. Experienced gatherers could discern between valuable medicinal herbs and nutritious wild vegetables. They carefully plucked the trees with their tools, sparing their roots to ensure sustainable harvesting. In a corner of the resource collection area, there was a small mine. The entrance was narrow, but the interior revealed a hidden world. Miners, wearing mining lamps and armed with pickaxes, explored the darkness for precious ores such as iron and copper. To facilitate resource collection and transportation, simple roads and tracks were built, with carts and horse-drawn carriages bustling through them. The entire resource collection area was brimming with vitality, as the hard work of the people provided a steady supply of materials for the base's development.

In this resource-gathering zone, farmland resembles a emerald green, embedded in the earth. Ridges are neatly arranged, the soil rich and soft. Survivors arrive early in the morning, bent over, tools in hand, toiling diligently. They sow seeds of hope, meticulously watering, fertilizing, and weeding. Wheat waves sway gently in the breeze, and vegetables flourish in a vibrant scene. Not far away, a well, like the eye of the earth, its clear water shimmers in the sunlight. People busily gather around it, drawing water to irrigate the fields. Windlasses creak, buckets rise and fall, the well water nourishing every inch of the land and nurturing people's hopes for the future. The mine, like a silent giant, holds endless treasures. The mountainside is covered with traces of mining. Survivors, helmets on their heads and picks in hand, diligently dig within the mine. As ore was hauled out by truckload, their faces caked with dust, but their eyes shone with determination. To grow more food, the survivors meticulously selected high-quality seeds and continuously refined their planting techniques. They toiled under the scorching sun, sweating without complaint. In the fields, they could often be seen exchanging experiences and sharing the joy of planting. Mining ore was arduous and dangerous, but the survivors remained steadfast. They trudged through the narrow mine tunnels, ever vigilant for potential landslides.
