The Dragon's Grand Design: A Stranger Saves the Crumbling Han Dynasty

Modern engineer Lin Fu transmigrates into the chaotic era of the Great Yong. Warlords carve up the realm, northern barbarians batter the passes, and refugees are everywhere. From the start, he has no golden finger, only a head full of math, physics, and chemistry. Purifying water, building walls, improving crossbows, reclaiming wasteland for farming: with one practical achievement after another, he goes from surviving in a refugee camp to making himself indispensable at the frontier army’s headquarters. But the greater his contributions, the more covert attacks he faces: framed by powerful ministers, betrayed by brothers-in-arms, and hunted down to silence him. At last, he sees the truth: in this chaotic age, skill can keep you alive, but it can’t win. Then he’ll find another way to live. A refugee army, an intelligence network, hard evidence, gunpowder: he puts everything he can use on the board, along with a mysterious map of the realm whose origins are unknown. The chancellor colludes with the enemy, the barbarians press at the borders, and the realm teeters on the brink of collapse. In this crumbling land, he intends to draw a new map.
