Zombie Apocalypse: Scavenging for Supplies with the System

[System + firearm progression + scavenging for supplies + balanced power scaling + squad growth + no saintly heroine + no thinking with his dick + multiple heroines, but not a harem]

[Read with confidence! I'm a full-time author, and I guarantee a complete ending!]

In the apocalypse, Wang Yuzhou obtained the Delta Force System. Whenever he opened a storage container, the System would provide him with extra supplies. He could even find [Mai Xiaowen's Detector]? With it, he could tell how many zombies were inside a house, so he never had to worry about there being rats among them again. Wang Yuzhou kept looting, and somehow even found [Red Wolf's Exoskeleton]! Now he no longer had to worry about being too slow to outrun the zombies.
