Zombie Apocalypse: Use the Delta System to Search for Supplies

[System + firearm development + searching for supplies + combat power without collapse + team growth + no holy mother + no sperm brain + multiple heroines but no harem] Don't worry about chasing books! Full-time writer, guaranteed completion! Wang Universe obtained the Delta system in the end of the world, and when opening the storage container, additional materials will be obtained through the system. Can even [Mai Xiaowen's detector] be searched? You can use the detector to know how many zombies are in the house, and you will no longer be afraid of rats among the zombies. Wang Yuzhou continued to lick the bag, and actually found [Red Wolf's Exoskeleton]? From now on, I no longer have to worry about being outrun by zombies.
