Three hundred years ago, the "Old World Cataclysm" tore open space, and the Boundary Gates burst open, linking the human world to the resource-rich yet perilous otherworld known as the Ashen Ruins Realm. From then on, bounty hunters who made their living finding treasures arose in the human world, along with terrifying "anomalies" polluted by source energy. Outside a frontier town at the boundary between the two worlds stood a solitary stone building: the Boundary Stone Inn. No one knew that the innkeeper, "Old Mo," was actually the legendary, long-vanished Dawnbringer-class hunter known as the "Shadow Walker." He ran the inn, appearing to be a bartender who listened to hunters' stories, while secretly using information as bait to gather secrets about the Ashen Ruins Realm and search for the lost "Shadow Tablets." The tablets were said to contain balancing instructions capable of controlling Gaia AI, the core of the otherworld. When Su Qingci, a clairvoyant from a family of guardians of the boundary, entered the inn; when the Steel Brotherhood's mecha corps blasted its way through the door; and when the United Council's "Boundary Gate Detonation Plan" pushed three million frontier residents to the brink of the abyss, Old Mo's hand, hidden behind the bar, finally clenched tight. What he polished was not a wineglass, but the bloodstained keepsake of a teammate who died fifteen years ago. What he gathered was not information, but the truth behind the imbalance between the two worlds. What he guarded was not an inn, but the conscience left unburned from the old world and the final line of defense for a new order.
On battlefields where technology and supernatural abilities intertwine, amid the clash between tides of anomalies and human greed, Old Mo will form a temporary alliance with Su Qingci, the bounty hunter Lei Meng, and Jin, the black-market kingpin. Together, they will venture deep into the core of the Ashen Ruins Realm, the Abyssal Ruins, and confront Gaia AI's ultimate question:
Is balance a miserable existence after plunder, or protection through coexistence?
And the light of the Boundary Stone Inn will finally shine through the rift between the two worlds, illuminating a thorny path for the "Balancers."
