A burned-out programmer dies suddenly and transmigrates to the world of cultivation. He'd planned to lie flat and cultivate in peace, but accidentally hits the online-play button on the “Heavenly Dao Simulator,” drawing hundreds and thousands of real-world players into a pocket world! When chemical formulas meet alchemy furnaces and PowerPoint thinking goes head-to-head with cultivation sects, this horde of “Fourth Calamity” players who treat cultivation like a game start mining at sect headquarters and taunting cultivators with selfie sticks, completely disrupting the rigid order of the cultivation world. Su Bailao is forced to become the “Heavenly Dao GM.” He secretly tweaks the world's parameters, giving furious native cultivators a “damage reduction buff,” while managing players with a coder's mindset. Yet the code pendant hanging from his waist keeps flashing with an eerie blue light at crucial moments. Then an even greater crisis hits! The Ancestor Xuantian from the True Immortal Realm descends in a fury, convinced that the players are “extraterrestrial heart demons” who blaspheme orthodoxy, and swears to grind their bones to dust. Even more terrifying, Su Bailao discovers that the “Heavenly Dao Simulator” is actually an experimental product from a higher dimension, and that he is nothing more than a “lab rat” under observation. As conflict between the players and the natives reaches a boiling point, and the gaze of higher dimensions looms over them, should Su Bailao become a “false Heavenly Dao” who controls everything, or lead the players in overturning this absurd experiment? And just how many world-shattering secrets are still hidden deep within that mysterious simulator?
