Surviving the Stone Age as a Modern Genius

Frodo transmigrated into the depths of 20,000 BC, a nightmare where mankind sits at the very bottom of the food chain. In this frozen hell, flint is the pinnacle of technology, and a single harsh winter spells extinction. Waking up in the starved body of a primitive boy, Frodo watches his tribe march to their slaughter. With nothing but fire-hardened sticks, they prepare to face an eight-ton titan: the Woolly Mammoth. While any other caveman would pray to the spirits for mercy, Frodo has the mind of a modern senior engineer. Instead of freezing in caves, Frodo invents underground heated floors, hot-brick ovens, and warm waterproof clothing. And the innovations only get more terrifying... Bronze Weapons; Ballista Crossbows; Stone Fortress Walls; Crushing Pit Traps; Secure Food Warehouses; Wheeled War Wagons. One by one, starving clans are absorbed, conquered tribes are united, and a unified banner rises across the lands to build humanity's very first kingdom. As stone fortresses replace fragile tents and smoke rises above the glacial tundra, neighboring chieftains and ferocious beasts look upon his borders in terror. Wait... how is a primitive kingdom hunting mammoths with modern siege warfare?! — Description from novelcodex.orgFull novel: Surviving the Stone Age as a Modern Genius — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
