A long novel! Over a million words, Western fantasy, one heroine, thoughtful character development, farming, and empire-building!
After transmigrating into the poorest baron in the Olayan Empire, Lin En Blackthorn faces hellish conditions from the start: barren, salty soil, a dilapidated village, usurious debts to the church, and a deadly winter wolf stampede arriving ahead of schedule!
At the brink of despair, his golden finger, the Eye of Rules, awakens, letting him see the loopholes in the rules governing all things! Flaws in battle aura? Defects in magic? Information about resources? Ways to optimize technology? Nothing is beyond it! But... why is the side effect so awful?! He suddenly confesses his love to the captain of the guards in the middle of directing a battle? Turns into a work-song conductor while optimizing production? Breaks into an awkward dance at the very moment his life is in danger?
Facing monster hordes, greedy nobles, the church's exploitation, and threats from other races, Lin En covers his face in embarrassment with one hand and grips his sword with the other. With his childhood-friend fiancée, a mage, by his side, he exploits loopholes, optimizes everything, and races up the tech tree with the Eye of Rules! Making gunpowder from saltpeter? Partnering to develop a magic crystal mine? Building up his territory? Recruiting talent? Watch this bankrupt lord start a spectacular farming-fueled comeback in another world, one mortifying mishap at a time!
