The zombie virus breaks out and the world falls into chaos. Zhu Ping'an, an ordinary young man who runs a canteen in an underground garage, accidentally obtained a mysterious system before the end of the world - the "Safe House Rules", which can transform any closed space into an absolutely safe refuge.
However, there are cruel rules hidden behind the system: "Law Points" are required to increase the level of the safe house, and Law Points can only be obtained by sheltering survivors, resolving crises, and revealing the truth. Each person taken in increases the power of the safe house, but it also attracts more powerful threats.
In the troubled times, Zhao Tiezhu, a local ruffian from the former community, took advantage of the fire and gathered a group of desperadoes with the intention of seizing Zhu Ping'an's safe house. Faced with the siege of zombies from the outside and the test of humanity within, Zhu Pingan appears to be withdrawn and indifferent, but in fact he takes in the old, weak, women and children again and again, and uses his wisdom to resolve the crisis. He discovered that the zombie virus was not a natural disaster, but a carefully planned conspiracy...
When Zhao Tiezhu colludes with foreign forces and attempts to destroy the safe house with a nuclear bomb, Zhu Pingan must choose between absolute defense and the redemption of humanity. What are the ultimate rules of safe houses?
