Building Weapons of War in Great Tang

I transmigrated as Huang Chao, and on the very day I wrote “Golden Armor Across the City” at the Chang'an examination hall, I landed at the top of the imperial court's wanted list. Imperial guards closing in? I snatched a halberd and took down four men in three breaths! Soldiers coming to suppress the bandits? I'd already returned to my hometown and used the profits from smuggling salt to build the first arms factory! Black powder, firearms, cast-iron cannons… The military engineering knowledge of a thousand years in the future was my strongest System. At fifty paces, my weapons pierced bright armor. One cannon blast brought down Luoyang's city wall! Li Shimin seized the realm with the support of the Guanlong faction. Wu Zetian controlled the court with her ruthless officials. But I, Huang Chao, would take a third path: Turn the smuggling network into an arms-trading empire spanning the Tang! Salt is no match for iron, and iron is no match for fire. Princes and nobles used my firearms to suppress rebellions, while regional military governors relied on my ammunition to fight one another. When the whole world depended on the weapons I supplied, the one who became emperor would be decided by my guns and cannons. (A story of crushing everyone in your path, packed with explosive thrills!)
