In an epoch where colossal beasts ruled the earth and the skies, humanity's existence dangled precariously on the edge of a knife. With no formidable claws, sharp teeth, or impenetrable hide, early humans found themselves at the mercy of these towering predators. They were close to being erased from the annals of history.

Enter Wu Xiaoming, a modern-day man betrayed in the cruelest of ways. His wife's treachery left him for dead, only for him to awaken in a time far removed from his own. Now inhabiting the body of a young primeval human aptly named 'Human', Wu grapples with the reality of his predicament. Though his body may belong to this ancient era, his mind, brimming with knowledge and experiences from the modern world, constantly battles to make sense of his surroundings.

Wu's initial thoughts revolve around vengeance and returning to his time. But witnessing the daily struggles and near-death experiences of his newfound tribesmen evokes a sense of responsibility in him. Armed with his unique knowledge, he offers them solutions to stave off the brutal winter and other natural adversities. But even with these advantages, one looming threat remains: the giant beasts that constantly terrorize humanity.

In a twist of fate, Wu stumbles upon the world of cultivation, a path that promises unparalleled power and might. Recognizing its potential, he embarks on a quest not just for personal strength, but to arm humanity in their battle against these titanic foes. Thus begins a riveting journey, where ancient traditions intertwine with modern wisdom, culminating in humanity's audacious bid for world domination.
