Isaac Kai was a pretty normal dude living in the 21st century, having lived a rather unremarkable life until a few of his investments paid off big time and he volunteered for an experimental mind upload program during the First Singularity. He then went on to live for a few million years, and did fuck all with it.But for the Isaac running in a historical Ancestor Simulation set in 2023, his lack of fame is his downfall. He's the perfect pawn for a Cultivation Sim on the brink of bankruptcy, desperate to pay off its mounting debts.Chosen by an underpaid and overworked AI with a questionable sense of humor. Isaac is yanked from his comfortable, albeit boring, existence and thrust into a world that's as rich and complex as it is utterly bonkers.Welcome to "The Dao of Simulation", where game development has gone off the rails and the laws of physics are more like mild suggestions. Isaac must navigate this new reality, where death is a one-way ticket to oblivion and a million Ancestor Worshippers are watching his every move.It's Xianxia but the author is abusing his Ritalin script. Nobody knows if the aliens are supposed to be there or not, but it's intentional that you can just be Cultivating and minding your own business till a peasant finds a railgun. Buckle up!
