Synopsis

Human beings are the very spirit of all life, while Gu embody the essence of heaven and earth.

When one’s worldview, values, and philosophy become twisted, they are no longer human but demon reborn.

The past fades into a fleeting dream, yet a name may echo anew in time.

This is the tale of a time traveler, reborn endlessly, forging his path through a world shaped by the mystical power of Gu (creatures of legends and malice).

Spring Autumn Cicada, Moonlight Gu, Liquor Worm, Great Qi Golden Light Worm, Slender Black Hair Gu, Hope Gu…

A world where these magical beings are nurtured, refined, and wielded.

At the heart of it all stands a villain of unparalleled ambition, Fang Yuan. Reborn 500 years into the past with the Spring Autumn Cicada he meticulously refined, he uses his profound wisdom and battle-hardened experience to outmaneuver his enemies. In a world of unrelenting cruelty, where power is cultivated through the mastery of Gu, Fang Yuan rises as a figure who bends the world to his will.

Unbound by morality, he acts with cold precision and ruthless intent, pursuing his ultimate goal without hesitation or restraint. In this realm of peril and opportunity, Fang Yuan seeks to ascend above all others, driven solely by his own strength and ambition.

Note:
Gu, legendary venomous creatures often tied to black magic, can manifest as various insects or snakes, bearing both mystical allure and deadly power.
The “three views” refer to one’s core worldview, values, and philosophy of life.

Editor's Note

💡 Forget the "anti-hero" half-measures. Fang Yuan isn't a misunderstood protagonist; he is a true demon. In a genre filled with hypocritical "righteous" heroes, Reverend Insanity offers a refreshing, cold-blooded perspective where morality is a tool and humans are just resources. If you can stomach a protagonist who would sacrifice a village for a minor cultivation boost without blinking, you are about to read the most logically consistent and brilliantly plotted Xianxia ever written.

Experience Curve

Vol. 1–2 (The Gu Yue / Shang Clan Arcs): ⭐⭐⭐⭐⭐ – The Perfect Foundation. Witnessing Fang Yuan restart his life with 500 years of experience is a masterclass in scheming. The "Gu" system is introduced with terrifying creativity.

Vol. 3–4 (The Northern Plains / Zombie Arc): ⭐⭐⭐ – The Endurance Test. The pace slows down significantly here. The "Zombie" phase is notoriously polarizing—some find it a brilliant low point for the MC, while others find it a repetitive slog. Stick with it.

Vol. 5–6 (The Fate War / Endgame): ⭐⭐⭐⭐⭐+ – Peak Fiction. The scale expands to the entire world. The "Fate War" is arguably the greatest arc in web novel history, where every scheme planted 1,000 chapters ago finally bears fruit.

WebNovelDB Review

10 /10
A cold, calculating epic that ruins 90% of other cultivation novels by comparison. The Good: The Logic of Benefits. Fang Yuan operates on a 100% rational "benefits" algorithm. He doesn't kill for fun; he kills because it's the most efficient path to his goal: Eternal Life. The world feels alive because every NPC (especially the Rank 8/9 Immortals) is just as smart and ruthless as he is. The Bad: The "Slog" Factor. The author loves detail. You will learn the history of every minor character and the biology of every insect. Volume 4, in particular, can feel like a grind. Also, be warned: the novel is currently indefinitely hiatus/banned, though the 2300+ chapters provide a substantial journey. For Fans Of: Warlock of the Magus World (Cold MC), Lord of the Mysteries (Deep lore), Reverend Insanity (The benchmark for the demonic path). Not For You If: You need a "moral compass," a romance subplot (there is none), or if you can't handle extreme, cold-blooded cruelty toward innocents.
