Doomsday: I Raised a Nine-Tailed Fox

When the doomsday comes, Lin Yue, the social animal project manager, picks up a fox demon cub in the ruins. The demon sealing ring around her neck shows a countdown of 72 hours - that is the limit of her life. While the survivors were still frantically trying to survive, Lin Yue took out Excel to build a zombie behavior model, used a Gantt chart to plan defenses, and broke down the cultivation techniques into quantifiable KPIs. And the fox demon cub he picked up, Su Jiu'er, whined for milk while unconsciously leaking demon fire that could burn away the tide of corpses. From Wal-Mart supermarket to Taoyuan city-state, from F-level ants to the founder of the scientific cultivation school, Lin Yue took his "mobile natural disaster level" cute pet, caught between madmen with superpowers, ancient monks, and high-dimensional observers, using project management thinking to mass-produce foundation-building warriors, and concluded a civilized symbiosis agreement with the nine-tailed sky fox. When the countdown reaches zero, all nine children and nine tails are frozen thousands of miles away; when the High Dimension Council arrives, Lin Yue uses the 3 million words of "Taoyuan Diary" as evidence and uses data to prove to the gods that this civilization is worthy of independence.
