统合物品分类系统

物品编号：CO-1
位置：LEVEL CO-4
安全性：危险

用途：

生成理论层级

状态：

较难获取

描述：

Object CO-1

Object CO-1外观为一个灰色的立方体机器，其是无法被以任何物理手段破坏的，其结构通常包含一个按钮和一个显示屏幕，但是少数情况会出现多个按钮或屏幕的情况，这并不影响使用，该物品在一些角落里有极小概率突兀的出现，如果长时间没人尝试接触，会融化为纯净水。

用途：

按下Object CO-1的按钮会立刻创造并切入到一个暂命名为“理论层级”的层级中。

理论层级的外形

理论层级外观是类似Level 0的层级，绝大多数是非欧几里得空间，其在颜色，实体，灯，地板，地形……等方面会有差异，并且每个理论层级有唯一性。

理论层级的生存难度

其危险程度（生存难度）也是完全随机的，其内可能包含精神污染，篡改又或是成群的实体，但是大多数理论层级生成难度普遍在宜居到Class5，有少数的理论层级生存难度为其他，但是可以忽略不计。理论层级内所有实体，物品，现象都是该理论层级独有的，具有唯一性

理论层级的出入口

理论层级被创造之后，其会在部分层级随机出现0到6个入口，并且理论层级有1到6个出口通向随机的层级，这通常是不可控的。

理论层级的其他性质

理论层级在被创造后，准时间72小时后会立刻关闭所有出入口，然后开始“坍塌”，过程时间多于24小时，在此期间其中的流浪者以及所有实体将陆续被切出到破碎之地，“坍塌”结束后该层级将永久性的消失。

该物品可以“保存”理论层级，被保存的理论层级的寿命会被延长至720小时，每一个该物品最多只能“保存”3个理论层级，该物品24小时内最多只能使用12次，过多使用会导致该物品溶解成纯净水。

MEG提醒您，不要保存容易误入的死区理论层级。
