Public Restroom Lord: I Upgrade My Shelter with the System

After staying up all night gaming, Lin Ye dies suddenly and unexpectedly transmigrates into a zombie-infested apocalypse. From the start, his supposedly safe shelter turns out to be an abandoned public restroom, and he gets bound to a restroom-upgrade System. His beginner’s draw gives him only a seemingly useless chef skill. Using the System, he keeps upgrading the restroom, transforming it from a dilapidated latrine into the strongest fortress in the apocalypse. By surviving through sheer caution, he establishes himself in the wasteland and becomes a low-key powerhouse no one dares provoke.
