Level M-1- “无常货栈”

---

注意

本层级的危险性无法被简单归类。威胁并非恒定存在，而是以完全随机、不可预测的方式显现与消失。经验、装备甚至运气都无法完全保证安全。上一秒的安全区，下一秒即可能成为绝地。在此，生存与死亡常系于一念之间，或纯粹的概率。

M.E.G. 监督者

描述

Level M-1 表现为一座无限延伸的、年代模糊的巨型仓储式建筑综合体。其内部结构高度一致且非线性，主要由以下要素构成：

• 无尽货架： 高耸至不可见天花板的金属货架网格，排列成近乎无限的狭窄通道。货架上堆放着尺寸、材质各异的板条箱、纸箱与木桶，其上标签的内容通常是无意义的字符、褪色的商品编码，或令人不安的模糊图案。
• 装卸区： 散布于货架迷宫之间，是相对开阔的区域。地面画有黄色标识线，偶尔可见闲置的叉车、托盘和集装箱。此区域光线稍好，但空旷感也更强。
• 管理区： 零星分布的办公室、配电房和工具间。门可能锁闭，也可能虚掩。内部可能有基本家具、老旧电脑或工具，同时也是“库存清点”事件的高发区。
• 环境： 空气弥漫着灰尘、陈旧纸板和微弱臭氧的混合气味。主要光源来自高处间隔遥远的荧光灯管，发出稳定但令人不快的嗡嗡声，并伴有频闪。背景中持续存在着低沉的、仿佛来自远方的机器轰鸣与管道通风声，其音源无法定位。

本层级的核心特性并非其静态环境，而在于其极端且不可预测的动态危险性——即“概率重构”现象。

“概率重构”现象

这是 Level M-1 的根本法则。整个层级的物理状态、实体存在、甚至物理定律的局部表现，都会以完全随机的方式在特定区域（范围从数平方米到整个区域）瞬间改变。变化无预警、无周期、无规律可循。其表现形式包括但不限于：

1. 环境剧变：

• 安全通道突变为绝路： 一条原本通畅的走廊，可能在踏入的瞬间被凭空出现的货架墙或深坑封死。
• 地面失稳： 坚固的水泥地可能突然化为流沙、粘稠的油污或炽热的金属网格。
• 大气异常： 某个区域空气被瞬间抽干、充满无毒但令人窒息的惰性气体、或温度在几秒内骤降至冰点或升至滚烫。

2. 实体概率性显现：

• 任何阴影、角落或集装箱内部，都可能毫无征兆地生成后室实体，包括但不限于笑魇、猎犬、窃皮者、悲尸，甚至更罕见或独有的形态。它们可能即刻攻击，也可能无视流浪者，或在几秒后自行消散。
• 实体也可能从原本无害的物品中“孵化”，例如板条箱突然爆开冲出实体，或墙上的污渍活化。

3. 物品与补给的不确定性：

• 一个标注“杏仁水”的纸箱，打开后可能是真正的杏仁水、污水、蜘蛛群、虚空，或是能短暂扭曲周围概率的奇珍异宝。
• 工具间的消防斧可能坚固可用，也可能在第一次挥动时像玻璃一样碎裂。

4. 局部物理定律扭曲：

• 小范围内重力方向突然改变。
• 声音传播失效或产生致命共鸣。
• 短暂的时间流速错乱。

关键点在于： 这些变化毫无规律。一个刚刚发生致命重构的区域，可能在下一秒恢复常态且长期稳定；而一个徘徊数小时都安全无恙的角落，也可能在你最放松的时刻变成陷阱。生存完全取决于你踏入特定坐标时，层级“掷”出的那枚“概率骰子”。

基地、前哨与社区

由于极端的不稳定性，在本层级建立长期据点被普遍认为是不可能的。仅有少数极度幸运或持有特殊物品的流浪者组成的小型、高度机动的“拾荒队”短暂存在，他们从不在一处停留超过一小时，目标通常是搜寻那些随重构现象偶然出现的珍贵物品。

发现与日志

• 初始发现： 最早关于 Level M-1 的记录来自一批从 Level 1 通过非标准门切入的流浪者。生还者仅有一人，其记录中反复提及“无法信任任何眼前的事物”。
• 流浪者日志片段：

“…货架上的编号自己在我眼前重组…我身后的通道不见了，变成了一堵贴满旧票据的墙。刚松了口气，就看见前面叉车的阴影里有什么在蠕动…我没看清，直接跑进了旁边的办公室。桌子上有半瓶水，我渴极了，但我不敢喝。谁知道喝下去的是水，还是液态的恐惧？”

入口与出口

入口

• 在 Level M-128 的墙壁上寻找一道生锈的金属卷帘门，有小概率切入此处。
• 在 Level M-37 的档案库中，偶然打开一个标有“库存总览（异常）”的文件夹可能将你带来。
• 在 Level M-167 的田野边缘，有时会出现一个孤立的仓库式建筑，进入即到达本层。
• 更多后室层级的非标准出口有小概率通向此处，通常与“仓储”、“物资”概念相关。

出口

• 不稳定性穿越： 遭遇某些特定类型的“概率重构”时，可能被抛入其他层级。例如，踏入一片突然变得像水面一样波动的地板，可能坠入 Level M-133；被一股凭空出现的强风卷入通风管道，可能最终掉落在 Level M-140。
• “安全区”门扉： 极罕见的情况下，在长时间（超过 12 小时）未发生任何重构的“稳定点”，可能会出现一扇标有“出口”的普通门。打开它可能通向 Level M-0、Level M-135 或 Level M-2，但也可能只是一个诱饵。
• 意识逃逸： 有未经证实的报告称，在面临极度恐惧和生死一线的重构事件时，少数流浪者通过强烈地“想象”一个安全层级，实现了“概率性切出”，但目标层级完全随机，且风险极高。

---

最后记录更新建议：

“如果你不幸踏入 M-1，记住：不要相信常态，不要依赖经验，不要留恋任何资源。移动，保持谨慎的移动，但不要以为移动就能避开厄运。在这里，生存不是技巧，而是一场……概率游戏。祝你好运，因为你最需要它。”
