Three Kingdoms: You Told Me to Take Up My Fief, So Why Did I Build a Steam Engine?

A mechanical engineer transmigrates into the body of Cao Zhi, who has just been banished to Linzi. Facing endless house arrest and surveillance, he unexpectedly activates the [Industrial Revolution Simulator]. As long as he has enough resources and craftsmen, he can unlock and build machines far ahead of their time! While officials sent by Cao Pi keep watch, his fiefdom quietly undergoes earth-shaking changes.

First, he improves the curved-shaft plow and waterwheel, increasing grain yields tenfold. Refugees flock to his lands, becoming his first loyal "workers."

Second, he builds a secret blast furnace, smelts high-quality steel, and forges revolutionary plate armor and crossbows made on an assembly line to equip his private guards.

Third, while Cao Pi is still congratulating himself over his cavalry, Cao Zhi's first "Heavenly Wolf" steam engine roars to life! Soon afterward, armored trains race across the wilderness, while "Dingyuan"-class river steam warships armed with breech-loading cannons patrol the Yellow River.

When drought ravages the north and corpses of the starving litter the land, Cao Zhi's fiefdom has grain piled as high as mountains. When Zhuge Liang makes his six northern campaigns and frets over the carrying capacity of his wooden oxen and gliding horses, Cao Zhi's steel army can transport a hundred thousand troops a thousand li in a single day. Cao Pi, Liu Bei, and Sun Quan stare in disbelief. "W-what kind of sorcery is this?" Standing atop a steam-powered mech, Cao Zhi smiles calmly. "This isn't sorcery. It's science."

Readers will be eager to find out which technology tree the protagonist will unlock next, and what world-shattering invention he will unveil to crush the champions of this age of cold weapons.
