When Luo Chong unexpectedly awakens in a primitive world, he finds himself in a fledgling tribe struggling to survive. Armed with modern knowledge and an unyielding determination, he embarks on a journey to transform a scattered group of hunters and gatherers into a thriving civilization.

From constructing wooden fortresses to implementing agriculture, from establishing administrative structures to fostering technological advancements, Luo Chong reshapes the fate of his people, one innovation at a time. But the path to civilization is fraught with dangers—rival tribes, wild beasts, and the ever-present threat of the unknown.

As he builds an empire from the ground up, can he navigate the challenges of leadership, warfare, and diplomacy? Will his vision of a powerful nation withstand the test of time?

Witness the rise of a primitive civilization, where survival evolves into conquest, and history is rewritten by a man out of time.

The Rise of a Primitive Civilization

As the temperature cooled slightly, Luo Chong eagerly smashed open the casting molds. Inside, a gleaming, pale golden axe emerged, slightly larger than a typical firefighter's axe, complete with a handle slot ready for fitting. The task of sharpening the axe blade was assigned to Cripple, while Luo Chong prepared for the next batch of castings.

He planned several tools with varying copper-to-tin ratios optimized for their specific uses: rulers and saws at a 4:1.5 ratio, engraving tools at 5:2, chisels at 4:1, planers at 3:1, hand drills at 4:1.5, and quadrangular spearheads at 4:1.

The hand drill was particularly innovative, cast as a 'T' shaped flat bronze piece, which was then heated and twisted into a spiral form while red-hot between two bricks, creating a helical drill bit. After cooling and refining the edges, a handle was attached for wood drilling.

As evening approached and the tribe members returned, Luo Chong ceased the smelting operations which had produced about 40 pounds of copper and tin plates using the limited ore he had brought back. The golden axe, now fitted with a handle made from a sapling and bonded with fish bladder glue, shone impressively.

Upon seeing the shiny new tools, especially the axes and saws, the tribe was fascinated but unsure how to use them. "What is this made from? Such a beautiful axe," Big Tree marveled, unable to take his eyes off it.

Luo Chong then presented a long spear with a bronze head and a handle smeared with fish bladder glue for reinforcement. The spear, measuring two and a half meters with a shiny metallic tip, looked formidable and majestic.

The tribe, especially the hunters like Beast Tooth and One Ear, who had grown accustomed to wooden spears, were visibly excited by the prospect of wielding such impressive weapons. "Chief, what are these made of? Do we all get one?" they asked eagerly, though they knew that if only a few were available, they might not receive any.

Luo Chong explained the materials were limited, showing a piece of copper ore. "It's made from this kind of stone. We didn't bring back much, but if we can gather more, everyone can have one." The tribe was stunned; they had seen the ore before but had never imagined it could be transformed into such fine tools.

Encouraged by Luo Chong's plans, the tribe agreed to focus on their current tasks until more resources could be gathered. That night, after a hearty meal, they gathered around as Cripple explained the smelting process, while Luo Chong set about creating standardized units of measurement, essential for their budding agricultural society.

Using a finely crafted copper ruler, Luo Chong established the basic unit of length as the centimeter, defined by the width of a fingernail, and marked out a meter on the ruler. He filled the etched marks with molten tin to make them visible, creating a durable measuring tool that would aid in all future construction and crafting within the tribe.

He then defined volume and mass based on this standard: one cubic decimeter was set as a liter, with weight directly correlated to water density—500 grams per half-liter, aligning with the metric system's ease of use and scientific applicability. He also introduced angular measurements, using simple geometric tools to establish a perfect right angle for reference.

As Luo Chong worked, he mused on the advantages of adopting a decimal-based measurement system over the traditional units used in his past life, appreciating the clarity and simplicity it brought to scientific and practical applications.

With these new tools and measurements, Luo Chong was not just crafting metal but laying the foundations for a revolution in how the tribe lived and worked. His efforts promised to significantly enhance their efficiency and capacity for future growth, setting a course towards a more structured and developed society.
