Opened a Portal to the Toxic Rain Wasteland? I Called the Cops and Handed It Over to the Nation

In the year 2025, an unprecedented supernatural anomaly shook the entire modern world. A mysterious dimensional gate materialized out of thin air, connecting the peaceful mortal realm to a terrifying doomsday wasteland beyond all imagination. Through the gate lay a hellish landscape corrupted by endless destruction, where ferocious zombie hordes roamed freely across barren lands, and corrosive black rain fell endlessly to erode all living things and man-made structures. The entire alternate world was desolate, fractured, and fraught with lethal dangers, yet it concealed enormous untapped value, holding countless relics of lost black technology that had vanished from the modern era. As news of the dimensional gate spread, panic swept through the public. Ordinary people were gripped by fear, terrified of the invasive doomsday creatures and unsure how to survive the potential cross-world crisis. Unlike the panicked crowd, the protagonist remained calm and rational. Fully aware of the mortal danger hidden within the wasteland and the immense potential of the lost technology, he chose the most righteous path. He took the initiative to report the bizarre dimensional anomaly to official authorities and completely surrendered control of the mysterious gate to the nation, refusing to covet the risky opportunity for personal gain. With the gate under national jurisdiction, the powerful and complete industrial system of the nation provided solid backing for all subsequent exploration and development. The protagonist was appointed to lead an official national expedition team, venturing into the perilous doomsday wasteland to launch large-scale resource development. The team exchanged abundant daily supplies and living materials for the wasteland’s precious cutting-edge black technologies, filling countless technological gaps in the modern world. During the development process, they fought relentlessly to crush surging zombie hordes that blocked their path, safely absorbed and integrated scattered survivor strongholds with humane policies, and eliminated various hidden dangers in the wasteland step by step. Through continuous exploration, construction and rectification, the protagonist and the national team gradually transformed the barren, lethal doomsday world into a stable, developable backyard territory, opening a brand-new chapter of cross-dimensional development and national technological advancement.
