Under the spotlight of the stars, in a place where the camera cannot see it, is the stage for real emotions and competition.
Welcome to "Threshold".
[This is the initial safe area, limited to thirty minutes. Please read and understand the following rules carefully, which will determine whether you can see the next sunrise.
[Rule 1: Please make sure you are within a stable coverage area of the light source. There are unknown things in the darkness that abhor steady light but are attracted to violently flickering or moving light sources. The "initial light sources" you currently hold are the main light in the living room (in abnormal condition and questionable stability) and the book's own light source. Please find or confirm other stable light sources as soon as possible.
[Rule 2: Do not attempt to leave the enclosed space you are initially in until you confirm the appearance of the "portal". The symbol of the "portal" is a door with the same system as the original doors and windows, but the material is a combination of wood grain and blood vessel-like veins, and the door handle is bronze. If you force a breakthrough at a non-"gateway", you will be responsible for the consequences.
...
[Rule 6: You are not alone. But please be careful when identifying "companions". Reliable peers will proactively mention and follow the rules. If you encounter an individual who claims "the rules are a scam" or who tries to lead you into violating any of the above rules, keep your distance at all costs and seek shelter from a stable light source.
[Rule 7: This book has a limited number of pages and cannot be destroyed. The book will disappear when all pages are filled or when the thirty minutes of preparation time expires, whichever comes first. Make sure you remember all the rules before doing so.
Survive, then explore. Good luck to you.
