The Frozen Man Wakes up and I Become a Doomsday Engineer

In 2062, the sun went crazy and a supernormal coronal mass ejection hit the earth head-on. The global power grid burned down, satellites fell, and the Internet, navigation, and long-distance communications were reduced to zero within a few days. Before they could recover from the blackout, mankind dropped all nuclear bombs again - a war that turned half of the planet into wasteland. Twenty-five years later, in 2087. An engineer who was forgotten in an underground freezing laboratory unexpectedly woke up from the freezing chamber. He has no powers, no system, not even a decent gun. He only has engineering drawings in his head, a set of disassembly and repair tools, and extremely low trust in "people" themselves. In the eyes of others, this world is: radiation zones, warlords, scavengers, pirates, and remaining governments. In his eyes, this was just a huge circuit board that had been burned through - the power grid was disconnected, the track layer turned into a debris field, the city's infrastructure was in shambles, and various forces were like a pile of garbage wires that were randomly plugged in and connected, and would explode again at any time. Therefore, the first thing he did was not to be a savior, but to repair his "machine" until it could run, and then start from a building, a street, or a market: finding water, pulling up a small power grid, repairing workshops, modifying weapons, drawing defense lines, treating scattered people and cities as engineering sub-modules that must be redesigned and rewired. From being a scavenger alone, to being the chief engineer of a small town, and then being targeted by all forces as a "doomsday engineer", this is the story of a man from science and engineering who uses wrenches, explosives and project management to "survive" in the wasteland and upgrade to "cultivating civilization".
