Simon, heir to a family of agronomists, transmigrates into a fantasy medieval world and inherits a remote barony plagued by saline soil and home to fewer than three hundred people. Above him, enemies sever his spiritual meridians and seize his land. Below him, his vassals plot against him while beast hordes gather at the border. Everyone expects him to die.
No one could have guessed that his mind holds a lost volume of the Divine Farmer's Manual, sealed away for a thousand years.
The first chapter teaches spirit-seed selection and cultivation, coaxing seeds to sprout and bear grain in three days and yielding ten times more per acre. The second teaches ley-line irrigation, channeling spiritual energy into the fields and turning saline wasteland into fertile land. Then there are the master craftsman's skills he brought from his past life: refined steel that outclasses enchanted armor, distilled spirit-wheat liquor that conquers noble banquets, and dragon-kiln porcelain finer than elven crystalware.
Starting with five acres of spirit fields, he builds prosperity through farming, supports his army through trade, and expands his territory through conquest. While other lords are still chewing black bread in thatched huts, his lands already boast brick houses, paved roads, a clock tower that chimes the hour, copper-pipe running water, and rows of chimneys from twenty workshops. A visitor's first reaction on entering the city is, "This is more prosperous than the royal capital."
Others farm to survive. He farms his way to a super-city jointly recognized by three kingdoms. A lord? No, what he intends to build has never been just a territory. It's a city no one can shake.
