Reverend Insanity

The protagonist is Fang Yuan, an exceedingly ruthless and pragmatic cultivator who rebirths back into his youth after living for 500 years. Unlike typical heroic characters, Fang Yuan is driven entirely by self-interest and will commit heinous acts to achieve his goals of eternal life. His unapologetic, villainous nature is a major draw for fans of the series.

Instead of standard magical qi or pills, the novel's power system revolves around Gu, which are magical insects that grant specific abilities or powers. Cultivators must feed, refine, and combine these Gu insects to grow stronger, making resource management a core aspect of the plot. This system introduces highly strategic battles where intelligence and preparation often beat raw power.

Reverend Insanity faced strict censorship in China due to its dark themes, depictions of violence, and the protagonist's blatant disregard for traditional moral values. The official serialization on Qidian was permanently blocked in 2021 before the novel's official conclusion. This sudden halt left many plot threads unresolved, much to the frustration of its global fanbase.

The novel was written by the Chinese web novel author Gu Zhen Ren. It became one of the most popular and critically acclaimed titles in the dark xianxia genre before its abrupt cancellation. Fans primarily read it today via official platforms like Webnovel or through fan-maintained translation wikis.
