A car crash throws him into an ancient battlefield strewn with corpses, but also stuffs an entire modern knowledge base into his backpack. When refugees fight iron cavalry with wooden spears, Lin Jian quietly lights the gunpowder. When plague devours villages, he distills alcohol. In five years, he claws his way from a pile of corpses to the rank of Imperial Preceptor, reshaping an era with science. When he opens his eyes again, he's back in a modern hospital room, and only three days have passed since he transmigrated. Now he has the ruthless decisiveness tempered in ancient times in one hand, and cutting-edge modern scholarship in the other. This time, he's determined to reclaim more than the life he once lost.
