Liu Ji, an anti-narcotics police officer, dies while pursuing a criminal. When he opens his eyes, he finds himself in Liaodong at the end of the Ming Dynasty, in the first year of the Tianqi reign, reborn as a lowly foot soldier in the border army whom anyone can trample on. He has no system, no special advantages, only the instincts honed through three years of real-world anti-drug operations: observation, ambushes, and counterattacks. With the Later Jin cavalry bearing down on the border, he raids an outpost and captures the enemy commander, treating the traitorous general Li Yongfang as a living gold mine and extorting 200,000 taels of silver. After swearing a blood oath of brotherhood, he joins forces with four companions and carefully navigates the dangerous divide between the Ming and Qing. History provides the backdrop, but thrilling action is at the heart of the story. Watch a modern detective use modern thinking to dominate a seventeenth-century battlefield of cold weapons, rising from a disposable foot soldier to a mastermind who reshapes the entire strategic game in Liaodong.
