The Age of Gray Fog: 90 Days Before the End

In 2150, gray fog swept across the inner solar system, and 90% of humans mutated into semi-mechanical monsters "Gray Bodies" within 72 hours. Miner Lin Mo died in the disaster, but was reborn three months before the disaster. More importantly, he has a set of "civilization fire" technology tree blueprints from extinct alien civilizations in his mind - from water purification devices to controllable nuclear fusion, from traps to interstellar battleships, every technology is the key to rebuilding civilization. But the time is only 90 days. He must stock up on supplies, form a team, and establish a stronghold before the gray fog comes. When he led mankind to rebuild civilization in the ruins, he discovered that the gray fog was not a natural disaster - the "Evolution Protocol" project of the Mars Industrial Complex was out of control, and the technology tree in his hand was the testament of that extinct civilization to the next civilization. This time, the fate of mankind is up to him to choose.
