Prehistoric Civilization: The Blackstone Era

Aka, a worthless zero-ranker, is thrown into a death-trap mine, only to awaken Sera, an ancient consciousness that has slept inside him for six hundred years. She is the inheritance his mother bought with her life, and the perfect vessel the Obsidian Network has sought for 120,000 years. Three minutes to merge, god-tier power, at the cost of sharing one body and feeling everything the other feels: pain, hunger, and the urge to devour life. From Ashen Town to Gobekli, from the Bronze Council to the Abyssal Eye Church, Aka uses his mind to fight divine power and calculation to unravel reincarnation. And he gradually discovers that Sera is not the first to dwell within someone, and he is not the first Twin Zero. The 127 people before him all died. Some died to power, some to trust, and some because they chose to save everyone. Three hundred days remain. The node tide is about to arrive. This time, Aka will find a fourth path: Not breaking the cycle, not continuing it, but becoming the variable the cycle cannot predict.
