Lin San, a temporary worker at a modern library, falls from a bookshelf and transmigrates to ancient times, where he becomes a notorious brute infamous across the surrounding villages. In a thatched hut, he finds his wife, Su Qingyao, covered in bruises and timidly forlorn, and their adorable daughter Yaoyao, huddled in a corner and trembling with fear. The original owner had gambled away his money and planned to sell his daughter to pay his debts, then died by smashing his head against a pillar, allowing Lin San to take over his body.
Then he discovers that his mind contains a complete modern library. From hunting traps in the Wilderness Survival Handbook to secret seasoning recipes in the Spice Guide, from glassmaking methods in Basic Chemistry to firearm blueprints in Principles of Military Engineering, the treasure trove of human knowledge becomes his personal cheat code.
While others dig pits and set snares to catch a single hare, he uses levers and knots to build efficient traps. While other households season their roast meat with nothing but coarse salt, his secret spices send their aroma drifting for miles. While the powerful show off their glass cups, his transparent glass has already taken over the market. And when the enemy cavalry comes thundering toward them, a row of dark cannon muzzles already stands behind him.
From earning his first fortune with a roast-meat stall to building his own industrial empire, from a hooligan despised by villagers to a warlord who makes the dynasty tremble, Lin San uses knowledge to crush his era and firepower to reshape its rules.
“Everyone says knowledge is power.” Standing atop the city wall, he looks down at the countless troops and smiles. “Then are you ready for a whole new level of warfare?”
