After programmer Lin Xiao dies suddenly, the BUG System tosses him into the chaotic primordial world. But due to a system malfunction, he is reborn as an earthworm. With his Chaos Compiler, he turns code-based cultivation into a series of absurd stunts: helping Pangu mod the Sky-Opening Axe with liquid cooling, driving the Time Demon God insane with an infinite loop, and turning the Great Stellar Array into a 5G base station. When his quantum pill furnace explodes into a mushroom cloud and the Book of Life and Death gets rewritten as a blockchain, this coder with a punk hairstyle somehow compiles the Ninth Heavenly Dao on his ridiculous cultivation path. When it comes to bugs, everyone here is a junior!
