Heaven's Mandate [Xianxia, Progression Fantasy]

A detective from Earth is summoned by the Heavenly Dao into the Immortal Realm to solve strange conspiracies in a cultivation world before an entity capable of devouring Fate consumes reality itself. With every mystery he unravels and every breakthrough he achieves, he receives increasingly powerful, and increasingly demonic abilities. -- The Heavenly Dao was above all, existing before time itself. Until, an unknown anomaly that could consume Fate, latched itself into its crevices, manipulating the world to its own twisted designs. To fight an enemy that can foresee every move within its own world, the Heavenly Dao reached beyond it, bringing Mark, a detective from Earth, into a cultivation realm on the brink of change. After a close personal betrayal, Mark was expecting to fade into nothingness only to find himself awakening inside the body of a murdered city guard, surrounded by the corpses of his patrol team, with half the Guards' Office chasing after him as the culprit. To survive, he must solve the very conspiracy that killed him before his memories are searched and his impossible otherworldly existence is exposed. Yet, before even taking his first step into the world, he found a young mysterious Oracle already waiting for him, with knowledge of the secret he was trying to hide. As the two investigate into layer after layer of the city's corruption, they uncover a millennia-old plot threatening to consume not just Rivergate, but the very fabric of the world itself.  What to expect: Fast Cultivation. Weak to Very Strong. Fate and Demonic Abilities. Good Characters. Book 1 Done. Book 2 Almost there. Book 3 in progress.
