Countdown to Doomsday, I Plan to Build a Safe House

On August 1, 2035, an asteroid exploded in low-Earth orbit, and a ring of radiation dust enveloped the earth. Global communications were paralyzed, and ninety percent of humanity died from radiation sickness within seven days. The survivors face not only radiation storms and mutant beasts, but also the evil of human nature rampant in the wasteland. Lu Zheng is a retired engineer. In his previous life, he wandered in the wasteland for three years. In the end, he was pinned to the ground by a group of people, the fire ax fell, and everything returned to zero. Open your eyes again and go back to the nine days before Judgment Day. A deposit of 360,000 yuan, an abandoned air-raid shelter, and an old squad leader who can be trusted to support him. This time he doesn't want to be a stray wild dog - he wants to build a place in this wasteland where living people have the final say.
