Building a Fortress in the Apocalypse

[No System, one heroine, a gradual pace, with an emphasis on plausibility and immersion] [Please bookmark and recommend the new book] Three years into the apocalypse, Lin Bei collapses at the edge of a disintegration zone. When he opens his eyes again, he's in an office, 365 days before the apocalypse. He can't tell anyone, because “Otherworld Resonance” has sealed his lips: the more people know, the sooner disaster will strike. All he can do is quit his job, raise money, and find an abandoned factory where he can build a wall to protect himself. There's no System from the start. His only advantage is what he remembers about the apocalypse. After it arrives, the secrets of the precepts become a true weapon. Combat isn't about whose strength is greater, but who understands the other's rules better. On the night the city's lights went out one by one, the supplies in his factory were neatly sorted and stacked. The wall still stood, and so did he. From a single wall to a fortress, every wall he built ultimately became a refuge where people could catch their breath, if only for a little while, in the apocalypse.
