Lin Mu, a product manager from a major internet company, lands in the Wanli era and binds to the [Industrial Revolution Progress Bar System]. Every time he unlocks a new technology, he receives a supply drop of modern goods. By day, he promises the Grand Secretary, “Small changes in three years, big changes in five.” By night, he leads the Embroidered Guard in “building a wolf-pack team,” uses KPIs to evaluate eunuchs and palace maids, and manages the Donglin Party with OKRs. When he slaps steam engine blueprints down in front of the Wanli Emperor, the Ming dynasty launches into a frantic race to go from “feudal empire” to “global hegemon.”
