With the city on the verge of falling, the simple-minded apprentice Han Zheng inherits the last spark of the Shuofang Army: a recipe for a misfiring “thunderfire musket” and a dying young lord.
A brilliant engineering mind awakens in a badly wounded body, and scraps of knowledge are his only chance to survive. On the perilous northwestern frontier, he must use scrap metal to rebuild this city-burning weapon! He keeps a low profile, farms the land, secretly trains a militia armed with firearms, and ambushes powerful foes. When the “demon weapon of Shuofang” draws the attention of wolves across the realm, will the fire in his hands consume the age of chaos or set the world ablaze?
