I Exploited the Stone Age Until I Became a God

Ning Dapao, a socially anxious, chubby shut-in, finds himself transported to a high-magic Stone Age world. He discovers that the gamer slang he spouts can actually warp reality: when he shouts “Heal,” his wounds close; when he mutters about “pet-catching formulas,” the dinosaurs around him start mutating. So this hardcore gamer explains KPIs to mammoths while using exploit-level strategies to help primitive people build infrastructure and tame human-riding dinosaurs. In the end, with a band of brothers he has thoroughly conned and an elf girlfriend who earnestly studies him, he exploits bugs through a barrage of System errors and becomes the new world's God of Joy.
