The asteroid "Death-7" brings disaster to the world. Crimson spores sweep across the world. Human beings are transformed into bloodthirsty bone eaters. Civilization collapses. In the wasteland, arms are king.
The hardware store owner, Marine Corps, has no invincible superpowers or special forces background. He only relies on his almost instinctive talent for controlling weapons and his business savvy to survive in the apocalypse.
He started from a small hardware store, built strongholds, manufactured arms, and fought powerful enemies. Joining hands with the iceberg gunman Leng Yue and a group of partners, he built an arms empire covering thousands of miles in the wasteland, and became the "King of Arms" that everyone revered in the apocalypse. He used the barrel of a gun to guard a way for living people to survive.
