Lin San, a temporary worker in a modern library, fell off a bookshelf and traveled back to ancient times, becoming a notorious gangster from all over the country. In the thatched house, there is the scarred, timid and melancholy wife Su Qingyao, and the lovely daughter Yaoyao huddled in the corner, shivering. The original owner actually wanted to sell the daughter to pay off the debt because he lost a bet, so he hit a pillar and died, so he was allowed to occupy the magpie's nest.
Until he discovered that he actually had a complete modern library in his mind. From the hunting traps in the "Wild Survival Manual" to the seasoning secrets in the "Illustrated Spice Book", from the glass making methods in "Basic Chemistry" to the firearms sketches in "Principles of Military Industry" - the treasure trove of knowledge of human civilization has become his personal plug-in.
When others were still digging holes to snare a hare, he used levers and knots to design efficient traps; when other barbecues only had coarse salt, the aroma of his secret seasoning spread far and wide; when the powerful were still showing off their glass lamps, his transparent glass had monopolized the market; when the enemy's cavalry roared towards him, a row of black muzzles had been erected behind him.
From earning the first pot of gold from a barbecue stall to building his own industrial empire; from a gangster spurned by the villagers to a tycoon who makes the dynasty tremble. Lin San used knowledge to crush the times and used firepower to reconstruct the rules.
"They say knowledge is power." He stood on the city wall, overlooking the thousands of troops, and smiled slightly: "Then are you ready for the dimensionality reduction attack?"
