On the eve of the end of the world, former special police officer Lu Zhong was reborn.
In his last life, he was betrayed by his most trusted captain and died due to the causal erasure of the Rules Gate. Before he died, he saw a figure wearing protective clothing and heard a sentence: "The door is not a disaster, it is a key."
After returning from rebirth, there are still thirty days before the "Great Rip". He knows that the Gate of Rules is coming, he knows which areas will become purgatory, he knows who can be trusted and who must stay away.
There is no system, no space ring, only memories and combat experiences from previous lives.
He hoards supplies, builds safe houses, and cuts through old enemies' paths to promotion. In the apocalypse with twisted rules, he is not a savior, he just wants to survive with trustworthy people.
When seven doors of rules open at the same time, when sound can kill, time can be traded, and morality becomes a shackle - only those who have insight into the rules can find the glimmer of light in the darkness.
No CP, kill in moderation, team symbiosis. This is a story about rebirth, trust and perseverance.
