This is a completely pointless esoteric novel. It talks about Taoism, Buddhism, Heavenly Scriptures and all sort of stuff. But it's completely aimless since the story doesn't go anywhere. The protagonist gains strength easily - his system rewards him for ever captive demon he kills. He doesn't ever mature as a person, but he sure does gain a lot of powers (invulnerable body, 100,000 years Taoist cultivation etc).This author achieved a record. He made the most boring repetition vaguely interesting (all that happens in this story is description of the protagonist waking up, executing a demon, harvesting its organs, recording events in his journal/blook [now rinse, repeat forever]) - but so what? The heart of this story is pointless, there's no development in narrative, or the protagonist. It's a well-written tragedy. Shame since this novel clearly puts a lot of effort into world building.
