Humans are truly cunning; the world is a hive of schemes. In the world of Gu Masters, Gu — mystical creatures refined through relentless effort — are the source of every power, and to cultivate is to devour, scheme, and prevail.

Fang Yuan, a demonic cultivator who has already lived five hundred years, is sent back to his youth with all his memories intact. He is not a hero. He has no illusions about righteousness, gratitude, or love. He has a single goal: eternal life. And he will step over anyone, family, friend, or foe, to reach it.

Follow a protagonist who is unapologetically the villain of his own story as he claws his way up through a merciless world of clans, sects and ancient Immortals, one calculated move at a time.
