Candle Dragon Era: My Civilization Restart Plan

The sun dies completely after seventy-two hours. This is not dusk, but a cosmic silence called "The Candle Dragon's Sleep." The star's output returns to zero, the geomagnetic field is completely violent, and all electronic intelligence instantly disintegrates. Humanity will freeze to death in the dark cradle of the mother planet. Lin Han was reborn on the eve of the disaster, carrying not superpowers, but all the memories of his previous life as a top space city engineer. She knew that escape was a luxury, and the fire must be rekindled in the ruins with her own hands. As the dignitaries compete for the final space on the ship, she signs the handover papers for an abandoned Planetary Defense Era underground complex. As the survivors gnawed on tree bark in the freezing cold, the first steady glow of geothermal power came on at her base. When the predators screamed that the weak would prey on the strong, she opened the warehouse and found a lathe, a seed bank, and three floors of physical scientific documents. "Welcome to the 'Candle Dragon' shelter. The currency here is knowledge, and the law is the "Technical Code of Civilization Survival". If you want to stay, use your brain or hands to vote for the next era of mankind." However, as the "Planetary Environment Monitoring Terminal" deep in the base that should have been silent forever suddenly started autonomously, a broken code message from the depths of the star sea was parsed out: "Warning...'Candle Dragon' is not naturally dormant... Repeat, the death of the sun is man-made..." Lin Han raised his head, his gaze seemed to penetrate the rock formations and look into the cold deep sky. It turns out that the polar night is just the prologue. The real crisis never leaves.
