Su Mo, a dual PhD in chemistry and materials science, unexpectedly transmigrates to a savage prehistoric age and becomes the useless young chieftain of the near-extinct Azure Wolf Tribe. With giant beasts on the rampage, salt in short supply, and neighboring tribes invading, he draws on knowledge far beyond his time. Starting with pottery and refining pure salt, then moving on to blast furnaces, steelmaking, and synthesizing gunpowder, he leads the backward Stone Age tribe step by step to the heights of industrial civilization, building a materials technology empire that spans the continent.
