Man-Made Disaster, I Struggled to Survive in the Last Days

[Big male + zombies + no system + no time travel + no rebirth + no intelligence reduction + no invincibility] Red rainstorms swept across the world, followed by thick white fog. Three people and three axes cut out a way to survive in the apocalypse. College students, rich second generation, retired soldiers, and university teachers work together to survive. No background, no golden fingers, everything depends on your own efforts. The darkness of the apocalypse and the crazy human nature Gradually revealed without the constraints of the law. The law of the jungle is happening again in the apocalyptic society. There is no weird Madonna, no overflowing sympathy. There is only extreme self-interest and profit. If possible, I hope readers can read my works with a relaxed and tolerant attitude. Thank you all Yanzu Zhiling for your valuable opinions. I will seriously consider your suggestions.
