In a world of muskets, monied nobles, and stagnant tradition, Tang Mo is a man out of time. Transmigrated from the 21st century into the body of a struggling workshop owner, he finds himself in an era where war is a "gentleman’s game" of slow flintlocks and rigid formations. But Tang Mo carries the blueprint of the future in his mind. When the local nobility scorns his revolutionary needle gun, preferring the ornate box to the lethal "pearl" inside, Tang Mo realizes that progress cannot be bought—it must be forged. From a single workshop to a sprawling industrial empire, he begins a relentless ascent. He isn’t just building weapons; he is building a new world order. As steam engines replace horses and steel hulls shatter wooden fleets, the kingdoms of the old world tremble. To secure the resources necessary for his vision—specifically the oil-rich Black Dragon Island—Tang Mo must navigate a landscape of military conquest and political intrigue. In the clash between feudal arrogance and industrial might, only one will survive. The age of the Dragon Knight has begun.
