Waking up in a primitive thatched hut, the newly reborn Sol is instantly overwhelmed by the raw, sensory overload of his environment and the presence of two breathtakingly beautiful women, his aunt Lyra and the tribal healer Eira. As his brain undergoes a brutal data download of the original Sol's memories, he learns of the Osari Tribe's tragic history, including a devastating raid by the rival Vorakh Tribe that left most of their warriors dead and his own parents slaughtered. The original Sol had died of exposure during a failed rite of passage, leaving his family on the brink of starvation on the outskirts of the village. Weak, malnourished, and facing the contempt of the tribal elite, Sol realizes he has no traditional system but possesses a mysterious, dormant warmth in his chest. When a venomous Corpse-Stalker centipede threatens to kill Lyra, Sol experiences a sudden eruption of heat and projects a violent mental command that instantly obliterates the beast from within. This shocking display of power confirms his potential, but the energy vanishes as quickly as it arrived, leaving him physically exhausted and desperate to find a way to permanently unlock this cosmic force. He soon discovers that his physical recovery is tied to carnal release after Lyra helps him relieve his pain, sparking a devious plan to exploit this primitive world's lack of sexual shame. His newfound strength allows him to easily lift heavy clay jars and walk through the village with a sharp, commanding presence that draws both admiration from the local women and intense jealousy from the younger hunters. As the village prepares for the return of the hunting party, Sol encounters his former tormentor, the arrogant bully Vurok, who attempts to humiliate him in front of the crowd. Refusing to play the victim, Sol uses his improved agility to dodge Vurok's wild swing and lands a brutal punch straight to his gut, warning him that his torment is just beginning. However, the celebration is interrupted by the opening of the massive wooden gates, revealing a colossal prehistoric carcass and the arrival of the majestic tribal chief, leaving Sol to face a deeper web of tribal politics and ancient rivalries.

The return of the hunters brings a massive beast carcass to the village, but the distribution of meat highlights the deep-seated corruption of the tribal hierarchy as the weak are left with nothing but scraps. When Vurok attempts to withhold Sol's share and hands him a piece of filthy, dung-filled intestine, Sol snaps and slams the wet bone directly into Vurok's face, force-feeding him the waste in front of the stunned onlookers. This violent retaliation cements Sol's reputation as a dangerous wild card, but he knows he must rapidly increase his strength to survive the inevitable backlash. He turns his attention to his aunt Lyra and the beautiful neighbor Evara, using his refined Ash Gray energy under the guise of an ancestral massage technique to manipulate their senses and indulge in intense, boundary-pushing encounters. He discovers that these intimate acts not only satisfy his desire but also accelerate his physical recovery and refine his raw cosmic energy, turning his partners into devoted followers who crave his touch. To secure a permanent food source for his family and establish a secure base, Sol introduces a culinary revolution to the tribe by using modern knowledge to smoke river-hog meat and create a delicious, spicy soup using wild garlic and fiery chilies. Setting up a barter stall in the village square, he trades this addictive, life-changing broth for offal, bones, and discarded ingredients, effectively running a highly profitable trade that elevates his status. The soup becomes an overnight sensation, drawing crowds of hungry villagers and allowing Sol to harvest both raw cooking materials and the submissive devotion of the tribal women. His success transforms his family from starving outcasts into prosperous merchants, but his booming business and rapid rise to prominence do not go unnoticed by the elite hunters, who view his sudden influence as a direct threat to their established authority. Just as Sol begins to consolidate his power, he realizes that the physical and mystical demands of his cheat require him to target even higher-status women in the tribe, setting his sights on the healer Eira and the chief's cold daughter.

As his influence grows, Sol's mystical abilities reach a terrifying breakthrough when he encounters Nia, a beautiful hunter's wife, being assaulted by a brute named Grak. Guided by a surge of primal dominance, Sol unleashes a commanding wave of energy that forces the hunter to walk away in fear and compels Nia to submit entirely to his will. After a series of intense, dominant encounters in the forest, Nia becomes completely devoted to him, viewing him not as a captor but as her savior from a brutal marriage. This success confirms the terrifying potential of his mind-controlling aura, but Sol remains cautious of its limits, realizing that strong-willed targets like Vurok cannot be easily broken when their adrenaline and ego act as a shield. His caution proves justified when Vurok and four of his lackeys ambush him in a dark alley, seeking to restore their pride through a brutal beating. Instead of fighting back and exposing his true strength to the entire village, Sol strategically endures the physical assault, using his Ash Gray energy to shield his vital organs while letting them believe they have won. He limps to the cold river to wash away his blood and nurse his bruises, his mind sharp with a calculated plan for absolute vengeance. Learning from his friend Taru that the upcoming hunting rite will take place in the treacherous Vorash forest, Sol realizes this is the perfect opportunity to eliminate his enemies without leaving any evidence. The dense canopy and dangerous ravines of the forest provide the ideal backdrop for a series of fatal accidents. Armed with his rapidly evolving physical strength, his refined Ash Gray energy, and a cold determination to survive, Sol prepares to enter the deep jungle, ready to turn the arrogant hunters into the hunted and cement his absolute rule over the Osari Tribe.

Entering the vast wilderness to prepare for the upcoming hunting rite, Sol is forced to confront the true scale and danger of the prehistoric jungle, which serves as a harsh reminder of his physical vulnerability. He is quickly targeted by a venomous, brightly colored snake, a lethal predator that tests his primitive reflexes and physical agility to the absolute limit. In a desperate struggle for survival, Sol manages to dodge the snake's toxic strike and kills it with his crude spear, but instead of merely discarding the carcass, he feels his Ash Gray energy react to the beast's dead remains. He discovers that he can actively absorb the raw vitality and essence of the creatures he kills, directly boosting his own physical attributes and expanding his energy pool. This monumental discovery frees him from the limitations of a traditional web novel system, proving that he can evolve endlessly by hunting and consuming the dangerous fauna of Ossuaria. He no longer needs a blue screen to tell him he leveled up, as his body physically transforms and grows stronger with every victory. As a distant, chilling howl echoes through the thick canopy, signaling the approach of even larger prehistoric monsters, Sol realizes he is no longer the prey but a rising apex predator. With Vurok's group waiting to ambush him in the shadows of the Vorash forest and the chief's cold daughter still looking down on him with disdain, Sol embraces his dark path. He will use the upcoming hunting rite as his personal slaughterhouse, harvesting the beasts to reach invincibility and returning to the tribe to claim absolute dominance over every soul, proving that the modern degenerate has become the ultimate master of this savage prehistoric world.
