When he woke up, a natural disaster struck and the city was reduced to ruins. Others were scrambling for water, food, and cans. Civil engineering engineers were praying, but they silently stared at the abandoned excavators and cement mixer trucks. Lu Qiyan: "..." I got it right professionally, but not completely. On the first day of surviving the apocalypse, he set a small goal for himself: to dig an underground shelter that was safe enough. Later, the shelter was ventilated, connected to electricity, and a groundwater circulation system was installed. The neighbors who picked it up looked at the underground fortress that was comparable to a five-star hotel, and collectively fell into deep thought: Boss, did you do this before? Lu Qiyan pushed up his glasses and held up the helmet on his head: "Ji Cao, don't 6." While other survivors were still beating their heads to pieces for a piece of moldy bread, Lu Qiyan's infrastructure team had already begun a grand reconstruction plan. Pit No. 1: Ecological farm, self-sufficiency, realizing the freedom of fruits and vegetables in the apocalypse! Pit No. 2: Energy Center, solar, wind and water energy, disco dancing at night without worrying about waste of electricity! Pit 3: Fortifications, high walls, trenches, watchtowers, maximum sense of security! ️… Pit No. N: Huh? There doesn't seem to be any remarkable pre-war relics? Lu Qiyan originally wanted to be a contractor quietly, but his strength did not allow it. Unknowingly, his refuge has become the utopia that everyone longs for in the apocalypse. One day, the leader of the largest survivor force came for a "friendly visit". Looking at the group of engineers behind Lu Qiyan who were holding guns in one hand and blueprints in the other, and who were capable of both civil and military skills, they fell into deep self-doubt. Leader: "... Are you still recruiting people here?
