Abandoned by my team in the apocalypse, I grab all city treasures with scavenge radar

Mysterious dimensional rifts suddenly descended across the globe, dragging all of humanity into terrifying doomsday dungeons that shattered the peace of the modern world. Ordinary cities were transformed into zombie-infested death zones filled with hidden traps and endless dangers. Everyone was forced to embark on a cruel survival journey within these cursed dungeon realms. Lin Yu, a newly transmigrated penniless high school senior, found himself trapped in this deadly crisis with no background, no resources, and no special talents to rely on. While nearly all awakened unique superpowers to fight monsters and survive, he remained powerless, reduced to a worthless weakling deemed useless by everyone around him. The moment they entered the brutal dungeon world, his fate took an even crueler turn. His childhood sweetheart, a popular school beauty, along with his elite team members whom he had trusted for years, ruthlessly abandoned him without hesitation. They discarded him for his lack of superpowers, convinced he would only be a burden in the resource-scarce and perilous dungeons. Left alone, helpless, and plunged into utter despair amid hordes of wandering zombies, Lin Yu triggered his lifeline in this darkest hour and bound the powerful Survival Radar System. This exclusive system granted him an unparalleled scouting ability, capable of scanning every corner of a wide radius to mark hidden supplies, roaming zombie hordes, and potential danger zones with precise indicators. Equipped with a portable spatial backpack for unlimited item storage, Lin Yu began his unique scavenger journey. He wandered through ruined streets and abandoned buildings, collecting seemingly worthless discarded junk while uncovering well-concealed abandoned vaults that most survivors overlooked. Inside these hidden shelters, he retrieved rare medicine, powerful firearms, and even precious divine gear far beyond ordinary dungeon loot. While other desperate survivors fought and slaughtered each other fiercely over meager supplies and trivial resources, falling into endless internal strife, Lin Yu grew stronger quietly and steadily. He roamed freely across the zombie-infested city, avoiding pointless conflicts and harvesting top-tier resources unceasingly. Step by step, he accumulated formidable strength and rare equipment, breaking free from his identity as a powerless weakling. Eventually, he rose to unprecedented heights, evolving into the legendary King of Scavengers whose fame resounded across every corner of the wasteland dungeon realm.
