Doomsday Sign-In: Starting from Jie Hu, the School Beauty Goddess

When I woke up, civilization collapsed and the world became a bloody wasteland! Lin Feng, a social animal, was betrayed by his boss and his girlfriend, and was pushed into a group of zombies, but accidentally activated the [Doomsday Lord Sign-in System]! Check in at [Abandoned Police Station] and get the "Infinite Ammo Desert Eagle"! Check in at [Central Hospital] and get "Perfect T Virus Antibodies"! Make a special check-in at the [University Goddess Dormitory] to get a stunning school beauty and a super mutant pet! Those who bullied me, humiliated me, or betrayed me in the past life will definitely pay back a hundredfold in this life! While his former enemies were still struggling for a piece of bread, Lin Feng was already sitting on a mountain of supplies, living in an impregnable fortress, surrounded by beauties and loyal servants. This is a legendary story about a little man who relied on the heaven-defying system in the apocalypse to plunder resources step by step, subjugate the strong, suppress all dissenters, and finally became the sole ruler of this wasteland!
